What's the Average Cost for brand new Furnace-Ac?

Lots of people purchase their initial furnace-ac without knowing. Usually once they buy their house, the Air conditioning product is already installed. Even if people purchase their next Air conditioning system they frequently open the contact book and call the top Air conditioning contractor pointed out out there. This tactic will assist you to keep your house warm but can result in investing a sum that is a lot more than necessary.

You will find many different ways through which it's possible to minimize the price of purchasing and setting up a brand new furnace-ac. First contact several Air conditioning companies to request an offer. Bear in mind the decision a person makes shouldn't just rely on the price of the gear alone. Select a trustworthy contractor as it is crucial in determining the general cost and satisfaction. Various public and private organizations provides financing and rebate incentives for purchasing a brand new Air conditioning system.

Among the best methods to raise the need for a home is by improving the house with new furnace-ac. Among the great causes of upgrading would be to conserve energy. Protecting the power which is often used every month can substantially assistance to lower the bills. Assisting to save the homeowner cash on bills and improving the upfront market price of the home are simply two advantages of setting up a brand new Air conditioning system.

Many houses presently have older Air conditioning systems which use a refrigerant referred to as R22 refrigeration which is accustomed to relax the environment passing within the room. R22 is renowned for using up the ozone layer. To be able to prohibit all R22 chemicals from further using up the ozone, the federal government passed new laws and regulations that have been made mandatory for the new air conditioning units which were being installed to make use of merely a new refrigerant named R-410A. This R-410A refrigerant is more expensive but works well in not doing harm to the ozone.

Houses are usually operating around a 70-80% rate of efficiency which suggests that 70-80% from the energy can be used to operate the furnace in the home and also the relaxation 20-30% is wasted. At the moment occasions the majority of the furnaces which are being installed are 90% better or even more efficient which suggests that 90% from the energy is consumed, which can help to conserve great deal of money within the entire lifetime of the house furnace because of less waste.

Upgrading the gear is a great approach to improve a house however it does require upfront cost. First there's the price of the brand new Air conditioning system. This cost ranges between 0 -00 with respect to the brand, size and also the model. The typical cost for any new furnace is roughly ,400 for that unit and includes not one other elements costs which can be used for setting up the furnace. The cost of the new ac is between 0-,000 which is dependent upon the company, model and size. The typical cost for any new ac for any 2 bed room / 1 bath home is roughly ,200 that is only for the system and doesn't include any installation costs. The coil from the new furnace costs around 0- 0 which of the new ac costs roughly 0.

When you're ready to customize the Air conditioning system, cost is definitely an problem. You need to research your options, request plenty of questions and obtain a minimum of three quotes from trustworthy Air conditioning companies.

Greater SEER Alternative Ac and Electric Systems

It's not unusual to locate package and split system ac models within the Phoenix market which have been being used because the 1970's or 1980's. Since the average existence expectancy of this kind of Air conditioning devices are around twelve to 15 years, it's about time to retire a few of these tired old workhorses.

An additional benefit whenever you replace older ac systems could be a significant rise in energy-efficiency by having an associated reduction in energy costs. Considering the variety of discussion we've been hearing in news reports recently advocating many of us to become eco-friendly and save energy that's most likely not really an uncomfortable consequence.

Together with what's promising of one's savings you will find several factors the competent ac contractor could make you conscious of when it's time to replace older equipment. I must share a couple of of these along with you. First let us discuss split system warmth pumps after which briefly cover stuff that are typical to both package models and split systems.

As SEER (Periodic Energy-efficiency Ratio) rankings for brand new ac equipment have elevated, Air conditioning industry practices which have been marginal previously will no more be acceptable. Certainly one of individuals unacceptable practices happened whenever split system electric condensing models were changed. The most popular practice previously ended up being to switch the electric condensing unit without first verifying the new condensing unit was suitable for that old air handler. Several problems may arise whenever there's a mismatch between your condenser and also the indoor air handler.

The very first issue is the lower efficiency which will derive from changing a mature condensing unit without changing the environment handler simultaneously. The reason behind this really is that ac producers don't rate current model electric condensing models with "antique" air handlers which are two decades old. To offer the released SEER, a electric condensing unit should be matched up by having an indoor air handler or fan coil unit that it's been ranked with. Quite simply, should you use a new 13 SEER condensing unit by having an old 8 or 9 SEER air handler, the particular efficiency accomplished is going to be under 13 SEER.

Another problem is there might be a mismatch from the internal coil volumes between a mature air handler along with a more recent condensing unit. As minimum SEER mandates have needed elevated efficiencies through the years, producers make improvements to both indoor and outside coils to be able to increase warmth transfer efficiencies. More recent condensing models could have a different internal coil volume than a few of their antique alternatives. If your new electric condensing unit is a component of a classic air handler it may lead to improper operation either in the heating or even the cooling mode that will need periodic refrigerant charge changes and unnecessarily increase service costs. Additionally, it may lead to system reliability issues.

Another problem many of us are facing may be the improvement in the qualities from the chemicals and compressor lubrication that are used within the new systems. Since new ac equipment using R22 refrigerant can't be manufactured after 2010, the key producers have previously began making more recent high quality models utilizing R410a refrigerant and polyolester (POE) oils. The brand new refrigerant has qualities that are not the same compared to R22 that's been the main refrigerant for split system and package ac systems for many years. In a nutshell, R410a isn't suitable for the refrigerant flow control products within the older air handlers which were created for R22. Even when the flow device might be transformed, could also be problems that could develop with time when the original mineral oils aren't adequately washed in the system.

A 4th consideration may be the refrigerant line size. The brand new high quality R22 condensing models frequently require bigger diameter vapor lines than individuals which were initially installed using the old system. It might not be economically achievable to exchange the vapor lines, so you will see deficits in efficiency consequently from the elevated refrigerant pressure stop by the more compact than suggested vapor line. One possible means to fix resolve this problem is always to use a new R410a split system condensing unit along with a new R410a air handler. Since R410a generally requires more compact vapor lines than R22, it might permit the employment from the existing more compact vapor lines. Suggested methods for getting rid of residual mineral oil in the existing lines would need to be viewed when the conversion to R410a was implemented.

When the suggestions above factors are taken into account, it might be clearer that the most effective strategy would be to switch the indoor unit together with the electric condensing unit. Although this is more costly in advance, it can benefit avoid significant downstream issues later.

Now we have talked about issues unique to separate system substitutes, let us consider some factors which are present with both package models and split systems.

One problem that's present with both package models and split systems in greater SEER items is reduced cooling capacity at greater outside temps. This is often verified by checking manufacturer's rankings for that old ac system and also the new ac system at outside temps above 100 levels. The more recent high quality systems tend to get rid of sensible cooling capacity more rapidly compared to lower efficiency models which were manufactured previously. It is really an essential aspect when looking for a current system that's doing merely a marginal job of cooling the area it serves. A brand new system might have to be bigger in ability to make the preferred cooling effect in the greater outside temps we have seen in Arizona. There's a caveat with this particular also. You wouldn't want the alternative system to become grossly extra-large either or it won't perform as intended.

Another factor you will observe is that lots of the more recent systems have bigger cabinets compared to older style models. The bigger cabinet size may become an problem in limited areas. Since minimum clearances should be maintained, a brand new system might not fit in which the old system was installed. This consideration is going to be unique to every specific application, but you should know from it so you do not get an uncomfortable surprise.

One further item to understand regarding both package or split system substitutes may be the factor in equipment costs. Greater efficiency has a greater cost. According to one leading manufacturer's prices for any 5 ton package electric, the jump from 10 SEER to 13 SEER comes using more than a 30% differential in cost. If it's been some time because you have changed an aura conditioning system, you might have "sticker shock". Material cost increases together with using advanced technologies like variable speed compressors, dual compressors or unloading scroll compressors together with variable speed fan motors that has been enhanced control systems all lead to greater equipment costs. Keeping this in your mind when you're projecting future costs for Air conditioning equipment alternative will help you develop better alternative budgets.

How You Can Eliminate Fruit Flies Having A Homemade Fruit Fly Trap

Anybody that has ever created a couple of bananas sitting out or forgotten to alter their garbage knows very well the issue with fruit flies. It appears that when they have penetrated your kitchen area, you cannot eliminate them. You are able to scrub, clean, remove tempting fruit and spray the garbage can with disinfectants, however they always return. You cannot help but cringe just searching their way.

We've always had issues with fruit flies, and among the primary reasons because we reside in a condo by law - must recycle. Due to where we live, we must keep our recycling containers inside until they may be discarded once per week. When the recyclables aren't washed good enough after getting used, they create an ideal breeding ground for fruit flies. They love items of decaying food remains and appear to thrive in the littlest amount. When fruit flies relocate, they just do not wish to leave and can lay eggs on and in anything possible - fruits &lifier veggies left around the counter, sink drains, garbage disposals, empty bottles &lifier cans, garbage bags, as well as mops and rags.

A Couple of Fun Details About Fruit Flies:

- Can lay as much as 500 eggs at any given time

- All of their lifecycle is finished within per week

- While considered mainly a pest, they have the possibility to contaminate food with harmful bacteria

Everyone knows that getting rid of the meals, eliminating the garbage &lifier cleaning plays a large role, but we understand what it's prefer to move a bit of fruit and also have a swarm of fruit flies fill the environment simply to escape your attempts at killing them. Where could they be gonna go? Clearly those floating can not be easily taken or wiped out, so they'll linger about until they have some other spot to lay eggs and also the whole cycle begins again.

In most my attempts, I discovered the easiest method to capture and take away those that escape is to produce a simple trap utilizing a jar, plastic wrap and a bit of food. Here's how it operates:

1. Obtain a small jar you do not intend on using again ( just like a baby food jar or something like that similar ) and clean it well. Make certain it's not a jar having a funky smell like a used pickle jar or something that use to possess strong spices or herbs. You'll need a clean, odor free jar.

2. Have a slice of blueberry and put within the jar. For this reason you'll need a clean, odor free jar - to ensure that the blueberry smell will not be overpowered by other not-so-tempting smells. Blueberry appears to operate the very best, however, you can experiment.

3. Fit a bit of plastic wrap over the top jar, ensuring they fit tight and well sealed round the edges. Then have a pen or pencil and poke four to five holes within the plastic, just large enough for any fruit fly to suit into. When a fruit fly crawls in, it cannot escape. What you know already they'd just fly out with the holes, however they will not!

4. Put the jar within an area where you've seen probably the most fruit flies. With respect to the quantity of fruit flies you've, you will probably start to see the jar fill in just a couple of hrs. After 24 hrs, you'll uncover precisely how bad your fruit fly issue is!

This straightforward, affordable &lifier safe method works perfectly and when you wouldn't want the jar on public display, you could slip it behind the garbage can, within the cupboard or perhaps underneath the sink (Just don't be done with it!). You will need to empty the jar every 3-4 days before any eggs are able to hatch. While adult fruit flies can't easily escape with the holes, their maggots can effortlessly, and on top of that - they're disgusting to determine moving around within the jar. You won't want to see this stuff moving in your counter!

Cleaning up the jar should not be considered a problem. For those who have a sort heart, you are able to decide to allow them to go outdoors. Personally, I spray the small buggers with bug spray, clean the jar and begin the entire process once again basically think you will find still some fruit flies left to capture.

For bad fruit fly problems, you will need to make use of this way of a great two days to make certain you've taken nearly all fruit flies. You may even desire to use a couple of jars in various places. Before lengthy, your kitchen area is going to be normal again.

Gas Machines Versus Gas Machines

Generator maintenance must be carried out regularly regardless of what fuel type you utilize. Many people are kids concerning the generator until it breaks. They do not care where they have it. They do not care the way they have it. They merely worry about the conclusion or just how much it is. What that thinking does is shorten their existence style. They do not look beyond then finish of the nose. What's occurring is, first, people don't know very well what their demands are. Next, they don't comprehend the distinction between their demands as well as their wants. Many people believe they are able to make use of a 15 KW generator having a 5 ton ac. Your whole load has to be calculated with a trained professional. Once he installed machines, he'd discover some issues that were occurring with certain machines or certain installations. The installer will normally get a concept of the abilities of individuals machines and also the producers. They tell you they are in keeping with the abilities of the items they are able to handle. But many of producers often overstate the capacity of the generator.

The maker can suggest a dealer in your town for those who have an issue. He'll come to where you are to visit your problem. First, if he's an authorized master electrical installer, he already knows what's essential to perform a set up and whether that installation is true and based on code. Second, he needs to be considered a factory trained repetition he recognizes that generator. They know the way it works around the house. Third, he needs to come to make certain it's not a hazard towards the person or people who reside in the home. I've come across many machines which were installed within vehicle port. It's illegal to achieve that due to deadly carbon monoxide buildup that may occur within vehicle port. Individuals are constantly saying that's OK. It's OK until somebody dies.

Can there be any distinction between gas and gas? There's a positive change. The BTU of warmth of gas allegedly burns warmer. The fuel burns warmer of computer does in gas. So, in gas, the fuel burns rather less or otherwise as hot. Therefore if this does not burn as hot it does not provide you with that engine horsepower that much cla of horsepower that you'll require within the engine.

An 18 KW in gas is equivalent to a 20 KW in gas. Really, gas isn't as effective as gas. Gas is much more effective. For those who have a 20 KW in gas, it'll stay 20 KW. In gas, it drops to 18 KW. It drops 2 KW. Some producers have permitted for your drop although not much. They aren't saying anything about this. They will not discuss it. They aren't allowing it to recognized to the general public or through their sellers or producers. They simply say that it's capable or even the same. It's not exactly the same. The fuel burns in a different way. Gas burns warmer than gas therefore it provides the engine less horsepower therefore it's less KW.

Some engines perform in a different way. Diesel works in a different way from gasoline. Gasoline burns warmer than diesel. However, you have greater performance engines in gasoline than you need to do in diesels. However in diesels you've got a much more torque engines. You've high compression torque engines. But you need to since the only factor capable of burning more diesel is ignition sources or high compression diesel engines.

The fuel you utilize to operate an electrical generator can have an affect on how efficient it runs to your requirements. Employ a professional before ordering and setting up an electrical generator.

Energy-efficiency And Air conditioning Technology

The following overview offers a quick reference to key considerations with some of the most effective technologies. As with lighting, trial installations are a good idea; so is working with manufacturers and distributors.

Getting the most from HVAC controls

Because a building's performance can be dramatically improved by installing and fully using HVAC controls, it is essential to understand and correctly use those controls. The place to start is with a close look at what is really transpiring in your building, 24 hours a day, seven days a week.

What is happening with each piece of equipment? On holidays? Weekends? As the seasons change, do your operations change? It is important to understand where and how energy is being consumed in order to identify where waste is occurring and where improvements can be implemented. Then it is imperative to ask, "What exactly do I want these controls to do?"

Energy management systems (EMS) are designed to run individual pieces of equipment more efficiently and to permit integration of equipment, enhancing performance of the system. In a typical EMS, sensors monitor parameters such as air and water temperatures, pressures, humidity levels, flow rates, and power consumption. From those performance points, electrical and mechanical equipment run times and setpoints are controlled.

Seven-day scheduling provides hour-to-hour and day-to-day control of HVAC and lighting systems and can account for holidays and seasonal changes. As the name implies, night temperature setback allows for less cooling in summer and less heating in winter during unoccupied hours.

Optimal start/stop enables the entire system to look ahead several hours and, relative to current conditions, make decisions about how to proceed; this allows the system to ramp up slowly, avoiding morning demand spikes or unnecessary run times.

Peak electrical demand can be controlled by sequencing fans and pumps to start up one by one rather than all at once and by shutting off pieces of HVAC equipment for short periods (up to 30 minutes), which should only minimally affect space temperature. Economizers reduce cooling costs by taking advantage of cool outdoor air. Supply-air temperature-reset can prevent excessive reheat and help reduce chiller load.

An EMS can provide an abundance of information about building performance, but someone has to figure out what they want the EMS to do and then give it directions. Calibrating controls, testing and balancing are key to any well-maintained HVAC system, but are especially critical to optimize control efforts.

Variable speed drives and energy-efficient motors

Variable speed drives (VSDs) are nearly always recommended as a reliable and cost-effective upgrade.

VSDs are profitable where equipment is oversized or frequently operates at part-load conditions. Savings of up to 70 percent can be achieved by installing VSDs on fan motors operating at part-load conditions. They may be applied to compressor or pump motors and are generally used in variable air volume (VAV) systems. They are also cost effective in water-side applications. Backward-inclined and airfoiled fans are the best VSD candidates.

Air-handler configurations controlled by variable inlet vanes or outlet dampers squander energy at part-load conditions. Using throttle valves to reduce flow for smaller pumping loads is also inefficient. The efficiency of motors begins to drop off steeply when they run at less than 75 percent of full load; they can consume over twice as much power as the load requires. VSDs operate electronically and continually adjust motor speed to match load.

The power to run the VSD is proportional to the cube of the speed (or flow), which is why this technology is so efficient. If the speed is reduced by just 10 percent, a 27 percent drop in power consumption should result. A VSD pilot study performed by EPA found that VSD retrofits realized an annual average energy savings of 52 percent, an average demand savings of 27 percent and a 2.5-year simple payback.

Perform harmonic, power factor, electric load, and torsional analyses before selecting a VSD. Though harmonic and power factor problems are not common in VSD applications, VSDs should generally be equipped with integral harmonic filters (or a three-phase AC line reactor) and internal power factor correction capacitors (or a single capacitor on the VSDs' main power line). In general, this equipment is not standard and must be specified.

Improved design and better materials enhance the performance of energy-efficient motors, which use 3 to 8 percent less energy than standard motors; units with efficiencies of 95 percent are available.

To achieve maximum savings, the motor must also be properly matched with its load, increasing run time at peak efficiency. Motors operate best when running at 75 to 100 percent of their fully rated load; motors routinely operating below 60 percent of rated capacity are prime candidates for retrofit. For motors whose loads fluctuate, VSDs should also be considered.

Smaller, more efficient motors are integral to a system downsizing stratagem; downsizing a 75 horsepower standard motor to a 40 horsepower energy-efficient model will result in energy savings of 15 percent.

Some energy-efficient motors have less "slip" than standard-efficiency motors, causing energy-efficient motors to run at slightly higher speeds; consider a larger pulley to compensate for the higher speed and to maximize energy savings. Installing a new pulley or adjusting the existing one can also be an alternative to a VSD when the cost for the VSD is prohibitive or the load has been reduced.

Improving fan system performance

A common way to improve the efficiency of the air distribution system is to convert constant air volume (CAV) systems to VAV. One authority on energy issues, E-Source, reports that "typical (VAV) air flow requirements are only about 60 percent of full CAV flow."

VAVs respond to load requirements by varying the volume of the air through a combination of pressure controls and dampers rather than by varying the air's temperature. According to the air pressure, fan power and volume of conditioned air are reduced, thus increasing energy efficiency. Of course, it is crucial to maintain indoor air quality (IAQ) when altering air handling systems.

To maximize savings, VAV components such as VSDs, variable-pitch fan blades, diffusers, mixers, and VAV boxes must be operating properly; careful zoning is also required to achieve VAV optimization.

E-Source recommends considering the following VAV retrofit procedures:

• complete load reduction measures and calculate the maximum and minimum air flow requirements,
• measure existing fan performance; examine duct system for possible improvements,
• stage fans that are in parallel configurations,
• commission the system thoroughly,
• optimize static pressure setpoint and implement reset control, and
• possibly remove return air fans.

Energy-efficient and properly sized motors are also recommended along with careful control strategies. Installing a self-contained, thermally powered device to each diffuser can add greater control to VAV systems by controlling individual spaces, rather than entire zones, and eliminate the need for VAV boxes. Such a device also offers VAV-style capabilities to CAV systems.

VAV retrofit costs and paybacks can vary widely. Installation problems related to fan control, reduced supply air distribution, location of pressure sensors and their reliability, in addition to deficient design, can diminish a VAV retrofit's performance. Because VAV boxes are relatively expensive and one is required for each zone, it is generally not cost effective to partition the space into many zones. Careful zone designation -- according to occupancy, internal loads and solar gain -- will maximize efficiency, increase comfort and reduce reheat.

When reheat cannot be eliminated, consider these steps to minimize it: ensuring thermostat calibration; increasing supply air temperatures during the cooling season; and monitoring reheat year round and possibly employing reheat only during winter months. Where reheat is used primarily to control humidity, a desiccant wheel or a heat pipe might be considered.

Downsizing existing VAV fan systems is a relatively low-cost way to save energy when loads have been reduced or when the air distribution system was oversized to begin with. The following are means to downsize fans or airflow requirements:

• Reduce static pressure setpoint to meet actual temperature and airflow requirements.
• Rightsize motors and upgrade to energy-efficient models; install larger pulleys.
• Replace the existing fan pulley with a larger one; that will reduce the fan's power requirements by reducing its speed.
• Make sure the fan's speed corresponds to the load. Reducing a fan's speed by 20 percent reduces its energy consumption by approximately 50 percent.

There are several ways to determine if VAV fan systems are oversized. If a motor's measured amperage is 25 percent less than its nameplate rating, it is oversized. If a fan's inlet vanes or outlet dampers are closed more than 20 percent, it is oversized. If the static pressure reading is less than the static pressure setpoint when inlets or dampers are open and VAV boxes open 100 percent, as on a hot summer day, the system is oversized. Again, be sure to consider IAQ requirements when downsizing air handling systems.

Chillers and thermal storage

No one wants to replace a perfectly good chiller just because of the CFC phaseout. But once load-reducing efficiency upgrades have been completed, it may actually be profitable to replace an oversized chiller. That's especially true given rising prices and tightening supplies of CFC refrigerants.

Oversized units 10 years or older are good candidates for replacement. A high-efficiency chiller reduces energy costs throughout its lifetime; initial costs are reduced because the replacement chiller is smaller than the old one. Depending on the old unit's efficiency and load, a high-efficiency chiller's energy consumption can be.15 to.30 kW/ton less, decreasing energy consumption by as much as 85 percent if combined with downsizing.

An alternative to replacement is to retrofit chillers to accommodate a new refrigerant and to match reduced loads. That may involve orifice plate replacement, impeller replacement and possibly compressor replacement, depending on the chiller's specifics.

Retrofitting may entail gasket and seal replacement and motor rewinding. Depending on the refrigerant and the way the retrofit is performed, the chiller may lose either efficiency or capacity. To determine whether replacement or retrofit is a better option, consider both initial and life-cycle costs.

Retubing the condenser and evaporator yields sizable energy savings but whether it makes sense, given its high cost, depends on the condition of the chiller. Water-cooled condensers are generally more efficient than air-cooled units. Because condenser water flows through an open loop, it is susceptible to fouling. Scale build-up will inhibit heat transfer efficiency; maintenance is therefore required to keep the surfaces clean.

Absorption chillers are an alternative to centrifugal models. Absorption chillers cost up to 0 per ton more than vapor compression chillers like centrifugal units, but can be profitable in areas of high electrical demand charges or where steam or gas is available, depending on the local utility rate structures. Using a combination of the two chiller types can reduce electrical demand charges.

Thermal energy storage (TES) uses conventional chiller equipment to produce conditioned water or ice (or occasionally another phase-change material) in off-peak periods. Water is withdrawn from storage during the day or at peak hours and circulated through the cooling system.

TES systems can be incorporated into new and existing systems and can provide partial load leveling or full load shifting. TES helps decrease operating and maintenance costs; in some cases, a smaller chiller can be specified. Some systems provide lower supply air and water temperatures, so air and water flow requirements can be cut.

Water-side improvements

Fill material, size and fan configurations affect cooling tower efficiency. Cellular fill (aka film packing) increases efficiency over other fill types. Oversizing the tower to allow for closer approach to ambient wetbulb temperature can improve its efficiency. Generously sizing the tower and increasing its share of the chiller load can make economic sense because a cooling tower's initial cost and energy use per ton are less than a chiller's.

At part-load conditions, applying a VSD to the fan (or pump) will improve the tower's efficiency. Systems with VSDs and several fans are more efficient when all tower cells are operating at reduced speed as opposed to one or two cells at full speed.

Because cooling towers contain large heat exchange surfaces, fouling -- scale or slime build-up -- can be a problem. The efficiency of improperly treated systems can be improved with effective water treatment. High-efficiency towers are available; induced-draft types are more popular and efficient than forced-draft towers. Performance can also be improved by increasing cooling surface area.

In traditional pumping systems, flow is generally constant volume; a throttle valve reduces flow at part-load conditions, inhibiting efficiency.

Installing VSDs on secondary pumps in variable flow systems, rightsizing pumps and motors to meet load requirements, and upgrading single loop systems to primary/secondary loop configurations can increase the performance and reliability of pumping systems. In upgrading chilled water pumps, it is important to meet maximum and minimum flow rates through the chiller.

Other cooling options

Desiccants are dehumidification materials which can be integrated into HVAC systems to reduce cooling loads and increase chiller efficiency while improving indoor air quality and comfort. Formerly found only in niche and industrial applications, desiccant cooling is extending throughout commercial markets.

Desiccants make sense when the cost to regenerate them is low compared to the cost to dehumidify below dewpoint and can reduce HVAC energy and peak demand by more than 50 percent in some cases.

Evaporative coolers provide one of the most economical and efficient means of cooling, using up to 75 percent less energy than vapor-compression systems. Though initial cost is typically higher, paybacks for evaporative coolers range between six months and five years. Though evaporative coolers are particularly prevalent in the arid West and Southwest, they can service most U.S. climates. E-Source states that, in combination with evaporative cooling, desiccant cooling can eliminate refrigerative air conditioning in many climates.

Hybrid systems that integrate evaporative cooling with conventional HVAC technologies offer additional opportunities. To improve performance consider lower air velocity; better fill materials; higher fan, pump and motor efficiencies, including VSDs; better belts or direct drive; improved housing; improved controls; and duct sealing. Proper maintenance is key to energy-efficiency.

Packaged air-conditioning units are typically found in buildings or building zones where the cooling load is less than 75 tons. Running these units at part load can severely reduce efficiency. They are generally not as efficient as chiller systems but can be upgraded and rightsized when replaced. Existing systems can be improved by using higher efficiency compressors, larger condensers and evaporators, and VSDs, though life expectancies of 10 to 12 years for these technologies may mean that retrofits are not cost-effective.

Heat pumps are among the most energy-efficient heating and cooling technologies available today. Low operating costs, increased reliability and long life expectancies improve their viability. They function best in moderate climates and proper sizing is critical.

Multi-unit configurations can service larger loads and provide zoning; large, modernized central units offering capacities of up to 1000 horsepower or 750 kilowatts are gaining popularity. Air-to-air type heat pumps are the most common because of low up-front costs; ground supply heat pumps are the most efficient but tend to have higher initial costs.

Boiler upgrades

Especially in colder climates, improved boiler performance -- with improved fuel and airflow controls over a range of load conditions and increased heat transfer surface areas -- can contribute substantially to energy savings. Smaller units arranged in modular systems increase efficiency up to 85 percent while small units replacing those with open-loop condensing systems shoot combustion efficiency up to 95 percent.

Boiler retrofits, combined with improved maintenance measures, can also increase efficiency -- up to 90 percent. New burners, baffle inserts, combustion controls, warm-weather controls, economizers, blowdown heat recovery and condensate return conversions provide increased efficiency opportunities. A smaller "summer" boiler might be a good option when a boiler is required year round though at reduced capacities in warmer conditions. The much smaller summer boiler is sized for reduced loads; the main boiler is shut down.

HVAC upgrades can provide tremendous economic benefits, improve occupant comfort and system reliability, and reduce operating costs. But to maximize benefits and minimize capital investment, load-reducing measures, such as lighting upgrades, should precede HVAC system upgrades.

Homemade Solar Power Panels - Where You Can Buy Solar Panels

If you have lately made the decision that you would like to construct a homemade cell, try not to know where you can buy solar panels continue reading. The correct answer is a typical problem that people ourselves had whenever we began searching for solar panels for the panel.

I'd initially began doing a bit of searches to find websites that offered solar panels. Although I discovered a number of the costs these were asking were quite steep! It might have require me to pay more to purchase individual cells of computer might have cost to purchase a completely new panel.

Since I Have wasn't going anywhere with my online searches I made the decision to in the manufacturer and find out basically could buy solar panels from them. They stated I possibly could, but each order would need to attend least 10,000. I had been pretty frustrated and so i requested them when they understood where you'll get cheap solar panels. I described what I used to be doing plus they offered me some golden nuggets of knowledge.

I used to be doing my search the wrong manner. Cells that I used to be searching at were what is known as Grade "A" cells. They described these cells are what's utilized in solar power panels because you will find simply no defects inside them however, you will find also Grade "B" cells which perform exactly like their Grade "A" alternatives but can be purchased for a small fraction of the price.

With a bit more information I refined my search and began approaching with many people who have been selling them at roughly /watt. I figured I possibly could most likely have them cheaper on my small favorite spot for alternative energy parts... eBay.

A fast explore eBay switched up a lot of people selling solar panels. The good thing was these were selling them for less than .50/watt (which has now dropped to under /watt). I had been excited to possess found a great affordable supply of cells to make use of in solar power panels.

If you have began your way to building the first homemade cell, try not to know where you can buy solar panels I suggest you take a look at eBay. They have got the very best prices I have seen and you will find always bargains available.

Air flow (CFM) Resolution of an aura-Source Electric (ASHP)

If you're a Air conditioning/R specialist, it is best to check any air-source electric (ASHP) for correct air flow over the coils when troubleshooting or throughout preventive maintenance.

Correct air flow is of crucial importance to the whole process of any ASHP. Area of the warmth transfer rate is dependent upon the air flow over the indoor and outside coils. When the air flow is wrong, then your warmth transfer rates are incorrect and may drastically modify the equipment's performance.

Accurate air flow measurement is important in troubleshooting any electric system. Actually, no refrigeration test applies when the ventilation volume isn't correct!

ASHP producers stick to the tenants from the Ac, Heating, and Refrigeration Institute (AHRI) with a "Test Stand Value" needing the measured air volume rate, when divided through the measured indoor air-side total capacity, mustn't exceed 37.5 SCFM per 1,000 Btu/h [this can be a more 450 cubic ft each minute (CFM) of air flow across an inside coil per 12,000 Btu/h of capacity]. Most producers make use of an acceptable selection of 350 to 450 CFM per 12,000 Btu/h of capacity, and also over 750 CFM per 12,000 Btu/h of capacity across outside coils (most outside fans move roughly 1,000 CFM, as much as 1,500 CFM, per 12,000 Btu/h of capacity). Within the Air conditioning/R industry, 12,000 Btu/h of capacity is known to like a "Ton" of refrigeration. Typically, most producers concentrate on around 400 CFM per "Ton" when rating their equipment.

Before carrying out any air flow determination, always make certain that registers and grilles are open filters and coils are clean, which blowers and fans are running correctly delivering air flow over the indoor coil and also the outside coil.

You will find various techniques which help determine the air flow amount across an inside coil. The indoor coil is usually checked because the air flow must mix this coil to permit the refrigerant either to absorb (ASHP cooling) or reject (ASHP heating) the warmth towards the appropriate "sink." In summer time, the "sink" may be the outdoors, and throughout winter, the "sink" is inside.

Probably the most broadly utilized techniques when checking ASHP air flow continues to be the "temperature rise" method over the auxiliary or emergency (support) heater(s). This process could be carried out no matter outside ambient temperature.

When carrying out this test, you should never forget that typically, most air source warmth pumps operate with similar air flow no matter mode of operation. In heating or cooling, or throughout emergency warmth or defrost, the electric simply provides the "same" air flow per ton over the indoor coil. The only real change can be done throughout the cooling mode, as water condensing around the indoor coil increases resistance slightly, lowering air flow amounts somewhat. Obviously, you may also change blower speeds and CFM amounts for either heating or cooling on some ASHPs.

To check on air flow (CFM) of the ASHP, you need to perform several dimensions and employ some math. The most popular formula for calculating CFM is:

Emergency Warmth Output(Btu/h)

CFM= -----------------------------

Temperature Rise x 1.08

You have to discover the CFM per Ton traveling with the indoor coil throughout heating or cooling modes. To do this, you need to put the system within the emergency warmth mode and put thermometers within the supply air and return air pathways as near to the air handler as you possibly can without struggling with the radiant effect from the heating units.

In the earlier formula, CFM equals the emergency warmth output in Btu/h. Since you'll be checking heating units, you'll be calculating electrical data. When finding Btu/h creation of the heater, you'll appraise the current and also the amperage in the disconnect for that heater(s) and record the. This can require utilization of a voltmeter as well as an ammeter.

Supply current increased by amperage equals wattage. Wattage increased by 3.413 (Btus per Watt) equals Btu/h and you'll then possess the value for that CFM formula numerator.

Within the CFM formula denominator, temperature rise originates from the main difference within the return air and offer air temperature following the heater(s) has/have stable along with a difference has happened. This difference (sometimes known as TR or &DeltaT) will be increased with a constant of just one.08 to obtain the modified temperature difference. Always seriously consider temperature change when locating the improvement in temperature.

This modified temperature difference may be the denominator for that CFM formula.

Once the formula is finished using the necessary inputs, the reply is the entire shipped air flow (CFM) traveling over the heater in emergency warmth mode. After this you simply divide this value through the tonnage from the installed outside coil to obtain the CFM per ton. The cooling air flow (CFM) is going to be close to this value or slightly lower because of elevated pressure drop from water condensing around the indoor coil throughout cooling. The ASHP compressor heating air flow (CFM) per ton is a similar value to that particular found from emergency warmth. The CFM per ton ought to be within the AHRI range to become acceptable.

If inaccurate ventilation (CFM volume) over the indoor coil (evaporator in cooling, condenser in heating) is decided, this case should be remedied just before further research into the refrigeration cycle.

Identifying ASHP indoor coil air flow (CFM) throughout emergency warmth example:

Two (2) Ton Unit

240 Volts at disconnect

20 Amplifiers at disconnect

Return air = 70ºF

Supply air = 88ºF
CFM = (240 x 20 x 3.413) ÷ (1.08 x 18ºF) = 843
843 CFM ÷ 2 Tons = 421.5 CFM per Ton

(This amount is suitable per AHRI)

It's also wise to look into the outside coil for minimal clearance per manufacturer round the unit from bushes, trees, and decks to permit proper warmth rejection within the summer time and absorption during the cold months. You may also determine the air flow over the outside coil using the product specifications in the manufacturer as proven below. Most ASHP outside coils will typically deliver near to this amount when the coil is installed properly and clear.

Top Ten Exercises Without Weights

Should you hate to visit a fitness center, you're not alone. The good thing is - you will get leads to enhanced comfort of your home with a few simple home exercises.

Body weight training Could be effective. It's really a replacement for weights, if required. Training making use of your own bodyweight like a supply of resistance is really a well established method to get results fast.

Listed here are 10 best body weight training exercises that provide you excellent workout routines and achievement - with no gym.

1. Supine Pull-Ups (works major muscles at the spine, shoulders, and biceps) Use two chairs along with a pole - huge broom handle is effective. WARNING: make certain the chairs are stable which the broom handle is powerful enough to consider unwanted weight. You may be Seriously hurt when the pole would break or even the chairs to slide. Lie lying on your back underneath a minimal bar. Grab the bar having a wide overhand grip. Pull-up. Lower and repeat for six-8 reps.

2. Supine Biceps Pull-Ups (biceps, some back) Make use of the same chairs-and-pole arrangement from #1. Sit underneath a minimal bar. Grab the bar having a reverse grip (palms facing you), hands about shoulder-width apart. Keeping the body upright, pull-up until your face just clears the bar. Concentrate on the tension inside your biceps, attempting to relax the relaxation of the body. 6-8 reps.

3. Push-Ups (chest, triceps, shoulders) The important thing when focusing on the chest area with Push-Ups may be the direction by which your elbows travel. Just like bench presses, the elbows must escape from Your Body to focus on your chest, and become stored Near To The BODY to focus on the triceps. Place each hands just outdoors shoulders, slightly behind the road of the shoulders. Hands pointing straight ahead, torso rigid like a board. 6-15 reps.

4. Tent Push-Ups (mainly upper chest) Assume the positioning in #3, but walk your ft forward so that your is bent in the waist, as well as your sides are at any height in mid-air. Bending in the elbows, lower yourself until onto your nose touches the ground. Push-up. Repeat. 6-8 reps.

5. Push-Ups, Triceps Position (you suspected it - triceps, plus some chest) Start with fingers facing forward set up from #3, hands slightly Under shoulder width apart. Decrease your body towards the floor keeping arms in upon your body. Push-up. 6-8 reps.

6. Triceps Dips With Chairs Together with your hands behind your back, support your self on your palms close to a chair. Both hands ought to be touching your elbows should position outward. Sinking within this position relieves lots of force on the elbow and shoulder joints. Lower yourself, keeping the back near to the chair. Bend your elbows back and slightly towards the sides. Keep yourself tilted slightly forward through the motion. Press yourself up to your arms are straight. 6-15 reps.

7. One-Legged Squats (front upper thighs, butt, hamstrings) Stand verticle with respect to some wall, about arm's length from it. Extend your arm to along side it and put your palm from the wall just under shoulder-height. Position the feet farthest in the wall at 45 levels. Bend another leg back. Keeping the body upright, lower yourself before the non-weight-bearing knee is near to (although not touching) the floor. Support yourself by leaning from the wall. Press yourself look out onto beginning position. Repeat 6-8 reps.

8. One-Legged Hamstring Bridges Lie lying on your back with one leg extended, heel on the floor. Contain the other advantage started. Pushing using your heel, flex your hamstrings to raise your body. Lower and repeat for 8-10 reps. Repeat along with other leg. You are able to control the resistance and also the degree that the butt lead by altering the length you set your heel in accordance with the sofa.

9. Runs Begin the lunge if you take a sizable advance, keeping the mind up and torso erect. Decrease your sides and permit your trailing knee to decrease to some extent right before it touches the ground - never allow the knee touch the ground. Revisit the beginning, push served by your forward leg after which take a step back once the knee is totally straight. Repeat along with other leg, 10-15 reps both legs.

10. Stair Running Stair running is not usually considered a resistance exercise, and actually, it can make hefty demands in your heart. However, additionally, it does an amazing job of conditioning the low body. In case your knees are who is fit, try doing 10-20 one-story sprints, ideally two stairs at any given time. As you become more powerful, build up the amount gradually, keep one hands around the stair rail to trap yourself should you lose balance. Have a larger challenge by putting on a backpack full of nice heavy books.

Leather Repair - How You Can Repair Torn Leather Chair

You will find so various sorts of automotive leather chair repair, with different situations and programs. You will find holes, scratches, gouges, cuts, scrapes, worn or cracked, and merely lower right grubby searching leather seats. I believe I acquired all of them covered, well in the following paragraphs we are likely to discuss how you can repair a little hole inside a leather chair lean back, for individuals individuals that do not understand what a lean back is well it is the upper area of the chair.

Now when I only say small this could obtain a tear as much as 1 1/2" to twoInch, most likely might go just a little bigger, but allows not push it, if it must visit the upholstery look for an place then that might be better a crappy searching leather repair on something which most likely wouldn't hold anyways. Much more doubt, place it.

Preparing a chair is paramount to success in almost any leather repair, along with a lasting leather dye job. So, prep the entire lean back, even though your in internet marketing just clean the entire chair, why don't you, but it's not necessary to, together with your preparing solution getting rid of all grease, grime, and muck. You'll need a clean surface along with a well prepared area to utilize. After I prep, I personally use an answer of rubbing alcohol, acetone, ammonia, and a tiny bit of Teaspoon substitute, with water inside a bottle of spray. Spray the chair using the solution and scrub having a scotch brite pad to scuff the leather chair for leather dye adhesion and take away any muck that's around the chair, then wipe clean having a clean lint free towel. When your clean, use a grip base primer towards the chair, It's my job to generally will dye the whole lean when I perform a repair or even the entire chair, but may you no longer need, to not require to prime the entire chair, but do clean the chair good this decreases on the quantity of leather dye used and also the ending result is a premium leather repair.

How to the opening. Allows say it's inside a V shape, just for instance. Like where you've gott'n from the chair with something inside your back pocket, ouch! I understand the sensation, in college I'd a 1986 Mustang SVO, unusual and nice vehicle (guy I miss that vehicle) and that i got to visit class having a pen within my back pocket and ripped in regards to a 2" V shape within the chair, I about puked immediately, not to mention at that time I did not know anything about leather repair. However I actually do and here you go.

Sand the region round the tear having a 240 grit sandpaper, this provides a bit more for that low warmth compound to grip to. Take a bit of underpatch material and slide the under patch underneath the tear with a set of forceps, permitting in regards to a 1/2" inside completely around. It's my job to cut my patches inside a circular shape, it causes it to be just a little simpler to slip under. You should use various kinds of under patches, I love the type that's covered on one for reds having a warmth triggered glue.

Now take a small amount of leather glue and spread a skinny coat around the patch around the bottom from the leather repair area. When the leather will lay lower easily and complement then great, but may it simply will not. Within this situation we'll use combo from the glue as well as your low cure leather repair compound and smooth a little amount within the patch then lay the leather lower. Spread a tiny bit of low warmth compound within the area and smooth it together with your pallet knife, recalling to keeping the area no more than possible, the more compact the greater. Now warmth the region together with your warmth gun, contain the warmth gun out from the leather repair and gradually move it in to the repair area, this gives you somewhat with additional control from the warmth, you won't want to burn and shrink the leather. The concept would be to cure the compound and obtain it to stick before you decide to prepare the leather, it is a skill factor, practicing to achieve perfection. When the compound is healed immediately press the grain pad inside your palm to the repair, don't press to hard, but firm.

At this time around utilizing a wet paper towel apply a tiny bit of grip base towards the repair area and dye together with your color matched up water leather dye. Dry thin jackets of dye, not wet. Then re-apply and lessen another thin coat of compound. Warmth again and grain then dye, obtain the idea, your work is building the repair up. Thin jackets of compound applied and healed then reapplied, tend to be better the other thick coat. After you have it developed and searching nice, blend the repair in to the relaxation from the chair as needed, by using thin jackets of leather dye to finish it. Drying out between jackets of dye having a hair dryer, and something great tip is rubbing the leather dye together with your hands to pressure the dye in to the creases from the leather helps a lot, you shouldn't be afraid to obtain your hands dirty. I only say that but I am allergic to rubber mitts, it bites, and so i get home every single day with dye throughout my hands, it is a discomfort, however i love the job and also the job looks better with some love applied on individuals leather chair repairs. Following the dye is healed, use a top coat of satin or dull leather obvious top coat combined with a little of slip additive added for that soft feel. Dry the chair completely, then apply your leather conditioner to complete and provide the chair the juice it requires along with a great feel and search for you.

Now you will find a lot of other versions for this fix, sometimes I will need to make use of an air dry leather repair compound over the top low warmth compound to lessen the leather repair. Sanding it having a 400 grit sandpaper until it appears right. You may also turn your air lower in your fresh paint gun until little tiny droplets are being released allow it a textured look, drying out between jackets. Texture films, may be used, but when you're doing so right the gun effect is effective. After I perform a leather repair I will not quit until it appears perfect.

Building a Recording Studio

Studio Considerations

The magic of the recording studio has often mystified even the most seasoned professionals. With all the knobs, switches and buttons on various gear and large format consoles, no wonder confusion sets in to most non-techies. Many people, especially artists, composers, producers, and engineers, will end up putting together their own studio for writing and pre-production, with some eventually deciding to take the plunge and create a full-fledged recording complex that is capable of recording major albums. This article will try to shed some light on the considerations to take into account when making a studio, be it a small home studio or a professional recording studio.

Is size important? Some may say it is so but this is not always the case. The dimensions of the studio are very important. A room too large may become over-reverberant or full of unwanted echoes. A room too small may sound tight and unnatural. It is important that the room size and room sound is relevant to the type of music you are recording. You don't want to go into a very small tight room to record BIG rock drums. Although, big room sounds can be achieved by adding external reverb effects to simulate rooms at a later time when necessary.

It is best to find the room that suits the sound you are trying to achieve from the beginning of the recording process. The smaller the room, the smaller and tighter the sound will be; this is not necessarily a bad thing. Small tight rooms can be good for vocals, guitars and percussion if you are going for a tight clean sound. Larger rooms have more air for the sound to travel in, so it will be in fact a bigger more open sound. The sound has a longer travel time for the sound wave to move, therefore the reflection from the walls will take longer to bounce back creating a bigger more spacious sound. The decision of size and sound has to be made early on before the recording starts. One advantage that a larger room will have is the ability to be scaled down by closing up the room using modular baffles or gobos (go betweens). Gobos are structures that are partitions, that help to block sound by placing them in between the musicians, instruments, and microphones. Placing the gobos around the microphone at a close distance will help a large room with too much ambiance sound smaller. This will eliminate the reflections coming off of the walls that are further away.

Small rooms can produce big heavy tight sounds with the absence of the decay from the reverb that is caused from big rooms. Sometimes a large room can sound like it's washed out, or far away. With a good engineer any room can sound amazing with a little adjusting. A poor sounding room can be manipulated to sound good, although it requires much more work and time. Deciding on the proper room size for your needs is critical to the sounds that get re-produced. This will highly dictate the type of sound the microphones will pick up.

Clapping your hands in a room can give a good representation of what a room will sound like. The reflection coming off the walls will be picked up by a simple hand clap. The true test is to try out some instruments or vocals and position them in various sections of the room until reaching the optimum sound quality. If one side of the room sounds bad try a different spot or move around into a corner until the sound is improved.

Experimenting with different sections of the room also keeps the sound fresh when recording many instruments. If the acoustic guitars are recorded in the center of the room, when the time comes to record the electric guitars you may try recording them in a corner of the room for a different room sound. This gives clarity on the final mix creating separation and providing more distinction on various sounds.

If you are starting your own studio, remember that the bigger the studio the higher amount the bills will be. The benefit is that larger studios can charge more for their studio rates.

Getting the Necessities

If you happen to reach that elite 2% and become that million dollar, hit selling, famous producer or artist (or if you just win the lotto), then you might eventually think about buying serious studio gear and setting up your own producer paradise.

Acquiring the proper equipment and labor is key to a great studio and successful recordings. Studio gear is expensive and the knowledge of those who use the gear does not come cheap. Hiring the right people can save money and time in the long run. Studio designers also are specialty breeds that can make or break your studio. Your buddy Joe the carpenter may be able to help build it for less, yet if the studio is not properly isolated for sound it is a great waste of time, energy and finances.

The studio engineer is also the focal point of the sound that is created. Having an experienced engineer involved in the process will make your sound have a character of its own. He is the extra set of ears that gives another dimension to your productions. He is also a critical consulting partner when building or choosing to rent a studio. Let the experts help you with advice, it will create less of a headache in the long run. The experienced engineer can fill you in on all the equipment needed for recording the music that is relevant to your world. He can also give some guidelines on how the studio should be setup before having to consult a designer. There is no room for guessing or assumption on these issues.

Check List: Part 1

When purchasing studio gear it is wise to research only what is absolutely essential for your style of music. If you're not recording live drums in your studio, there is no need to buy a plethora of microphones for them. By being patient and shopping around for the best prices, a mass amount of money can be saved in the end. When you save to 0 bucks on each piece of gear it really adds up in the end, and there is a ton of gear needed to put a proper studio together.

Below is a basic studio checklist that will be discussed in further detail in later articles. These are the essentials of modern day recordings and the tools that are most commonly used in the best studios around the world.

The Studio Gear Checklist:

Recording / Mixing Console

The engineer or producer operates the console that controls all of the levels for recording, playback and mixing.

This is the big board that has all the buttons, switches, knobs, faders which control the levels and signal routing for each instrument. This could be referred to as a board, console or mixer. The most common consoles in major studios are SSL (Solid State Logic) or Neve. The console is the most important piece of gear in the studio. It controls the overall operations of signal flow and sound manipulation. The console allows for each instrument to be on its own channel on the board. Each channel may then have effects inserted into its signal path to enhance the sound. A signal may also be routed to external gear for further manipulation. Anything that can be imagined, can be done. There are no rules for experimenting with sound. A signal can be sent to reverbs, delays, compressors, guitar amps, speakers in hallways for re-recording

Each channel strip on a decent console will contain: Faders, Preamps, Panning, Equalization, Filters, a Routing Matrix, AUX Sends and Returns, Dynamics, Muting, & Solo.

Other Features Of The Console: Inserts, Outputs, Monitoring, Automation, Fader Grouping, Bussing, Splitting...

Patchbay

Allows the studio to combine interconnectivity with all the equipment by using patch cables. The patchbay can be configured for each studio's specific equipment requirements. All of the outboard gear, console and recording devices inputs and outputs are hard wired to the patchbay. The Patchbays can be be analog or digital. The most common is the bantam TT cable configurations.

Check List Part 2:

Microphones Microphones pickup the initial sound source. The mic is the first source in the recording process receiving and converting the sound wave into electrical energy to be amplified, transmitted and recorded.

Preamps Amplifies the original signal coming from the mic or instrument. Gives initial control of the recording levels. Preamps are located on the console or as external outboard gear.

DI Boxes The Direct box is used mainly for instruments such as keys and bass to be compatible with mic inputs. The DI box transforms line levels of instruments to mic level for console and preamp inputs.

Compressors Helps to further control levels and dynamics coming from the preamp or console. Usually comes in rack mounted outboard gear or software plugins for DAWs. Compressors keep levels from peaking into distortion levels and help to bring lower levels louder.

FX Processors For special effects like adding space, dimension, pitch and time delays on signals and recorded tracks. Usually comes in rack mounted outboard gear or software plugins for DAWs. Multi-FX processors may have reverb, delay, flangers, EQ, compression and more all in one unit.

FX Pedals Small floor foot pedals originally designed for guitar FX processing. These pedals are created for distortion and special effects, which add space, dimension, pitch and time on guitars mainly, but are an inexpensive alternative used as outboard gear for other instruments.

DAW The Digital Audio Workstation is like an entire studio inside of a computer. Protools, Logic and Nuendo are just a few DAWs that provide a digital multi-track recorder, a virtual console, a wide variety of effects, editing, and sequencing(musical programming) possibilities. The DAW uses software, hardware and computers in combination to operate.

Check List: Part 3

Control Surface The control surface acts as a console that controls a DAW or external machine. The control surface usually has faders, knobs and buttons that are controlled by the computer connected to a DAW. This makes operating the DAW similar to analog operations by being able to put your hands on faders instead of clicking a mouse. Some control surfaces have all the same features as a console. The most common control surfaces are made by Digidesign.

Clocking Digital recorders use different clocking formats to operate properly. Digital units sample the sound to be replicated. Clocking refers to the amount of time in between samples taken for reproduction. If the digital clocking is off it will sound jittery or add noise to the sound in the analog to digital conversion. A quality clock will improve the sound. Some common digital clock sources can be found in products made by Prism, Rosendahl, DCS, and Aardsync to name a few. Some clocks have sync generators built in to lock up with other machines.

Sync Generator Generates tones to allow communication between machines so that several recording devices can be synchronized together and operate at the same speed. Clocking works with synchronization (sync) when analog and digital equipment is combined. Sync uses SMPTE, MTC (midi time code), Midi Clock, MMC (midi machine control) to allow recording on several DAWs and tape machines to be linked up together.

CD Recorder Records and plays back compact discs. Gives the ability to record stereo mixes and playback these mixes on other CD players. CD standard for consumer playback is a sample rate of 16 bit and a sampling rate of 44.1kHz. Sony, Tascam, Alesis, and Yamaha all make good studio CD recorders.

Tape Machines Recording machines that use analog or digital tape for recording and playback of music. Some purists in sound recording prefer the sound of analog tape. There are many digital tape machines used for recording both music and video.

Cabling Literally miles of various cabling could be needed for a single studio. Common cables in sound reproduction are XLR balanced mic cables and Unbalanced 1/4 inch instrument cables.

Monitors / Amps Speakers in the studio are referred to as Monitors. Powerful clean amps are needed to run monitors. Many monitors are self powered, which means that they have built in amplifiers. Monitors usually consist of high frequency tweeters, low frequency woofers and cabinets that contain the speakers and components.

Headphones / Distribution By using a set of earphones this allows communication between the control room and the studio, also allows pre-recorded tracks to be heard during the overdubbing process. Headphones are also referred to as cans.

Instruments / Keyboards / Drums / Guitars These are more of the tools of the craft. You may have all the best studio gear in the world, but if the instruments sound bad you are starting in the wrong place. Anything could be considered an instrument if it makes noise that could possibly be recorded on a record.

Amplifiers This is often referred to as an amp. Amps increase the amplitude or volume of electrical signals from sound waves. These are used in powering speakers. Guitar and Bass amps can be used for many other applications such as running a vocal or snare drum through them.

Microphone Stands A wide variety of sizes and styles are needed for a proper studio. The mic stand helps to get the microphone placed properly for the best sound quality possible.

Studio Furniture There are many types of racks and furniture designed to hold consoles and outboard gear. The interior decoration of the studio completely sets the vibe of the working environment.

Electricity

Nothing will work without electricity unless you're jamming at the local drum circles down on the beach. Electrical installation studio power is often overlooked. Studios will setup a "clean feed" that is a separate breaker from the rest of the general power that is being used for air conditioning, lighting and the basic necessities of the rest of the building. Have you ever plugged something in and heard that horrific buzzing sound coming from the speakers or guitar amp? This is usually due to bad electrical wiring, which causes ground noise. This is the first thing to listen for when going in to a studio session. A simple solution to the problem would be to use a simple ground lifter on the gear or lift the ground from a direct box which can also solve the problems. We will go into details later.

Isolated electrical circuits for each individual room are a must in a recording studio. The proper amount of amperage is also a must. Not enough amperage will surely cause your breakers to blow. Consult with an Electrician who is familiar with studio setups to insure that wiring and voltage is regulated and conforming with local codes.

Unregulated Power Supplies (UPS) should also be in place just in case there is a power failure. This will insure that valuable equipment will not blow up or cause a fire. If there is a case of a power outage the UPS will provide enough time to backup important computer files and safely turn off your equipment. Some studios will have complete generator systems in place to keep the studio running for the remainder of the session.

Improper lighting can also cause buzzing ground issues, especially fluorescent bulbs. Avoid using these in any studio. Dimmers can also cause many problems. The average household dimmers will surely put a damper into a clean sound. Make sure that professional grade dimmers are installed to avoid ground noise. Always listen carefully to signals being recorded before committing to a final take. There are a countless number of accounts that the engineer discovers electrical noise on takes during the mix process.

If you are serious about your studio, may I suggest balance power or a separated panel with neutral power conditioning. The evil problems of ground issues are a direct reflection of sources returning or looking for a different ground. Voltage potential between neutral and ground will certainly change your way of looking at things... for example, .5 volts between neutral and ground is the maximum allowance by UL code that electronics will operate optimally without potential induction issues. I would suggest having a meter installed to rate this. Logging this information and having a good rapport with the local electric company would not hurt at all.

Air Conditioning/HVAC

This is another very important area that is often not considered. Studio gear gets very hot. The lack of adequate cooling could result in equipment failure or damage. Blowing up equipment is no fun and it gets very expensive. Some recording studios have a separate Machine Room for computers, tape machines and power amps that is highly air-conditioned to keep everything cool. This also cuts down on the noise from the fans on such units, which can distract concentration from listening in detail in the control room. Having too much air conditioning could also result in moisture or condensation build-up that may also damage the gear. Water in general is bad for electronic gear.

The return air system is used to pull heat out of needed areas and also provides an air intake for the AC units. These are placed in key areas where there is a build-up of heat from the gear, for example near the console or in the machine room.

Separate Rooms: Control Room

Most studios have several isolated areas for recording, mixing, and production. Soundproofing is the main agenda when creating multiple rooms in a studio. To achieve this, the main objective is to make the rooms airtight. If air cannot leak in or out of a room, there will be less chance of sound leaking in or out as well.

Most pro studios have double doors that create a sound lock to help prevent noise leakage. They also have very thick double walls with interior air gaps to also help trap unwanted sound. The floors in the studio should also be floated which means they are lifted from the ground to help further prevent extra vibrations and leakage.

The first focus would be the Control Room where the mixing console and outboard gear are contained. This is where all of the recording and mixing is controlled, hence control room. The acoustics in this room should be designed for hearing the exact sound that is being recorded or mixed. The sound of the room should be as natural as possible for accurate representation of the original sound translated to the speakers in the room.

The first rule for an appropriate acoustically treated room is that there should be no parallel walls .If you were to clap your hands in a room with hard parallel walls you would here the sound bouncing back and forth, this is known as a flutter echo. This is neither good for recording or mixing. The trapping of unwanted bass is important for a room to sound great as well. Twenty five percent of the room should be assigned for bass traps for an adequate mixing room.

Separate Rooms: Live Rooms

The next focus of equal importance would be the Live Room where the music is recorded. This is where the musicians and vocalists perform on the microphones. Live rooms should have more versatility to be able to adapt to different recording situations. Wood floors for example are great for reflection of sound, which creates a brighter tone. If a warmer tone is wanted, one could simply place a rug on the floor. Many live rooms also have a great deal of glass to see between rooms for communication. This is also very reflective. Many studios use curtains to control the amount of reflections coming off glass or hard walls. Non-parallel walls are again needed to eliminate any flutter echoes.

Some studios also contain a vocal booth within the live room. This would be a smaller room designed for vocals. They may also be used for guitar amps and other instruments. There are no rules for what this can be used for; its main purpose is for additional isolation during the recording process. Glass doors or windows are used for visibility of the artists and those working in the control room.

Many elaborate studios may have multiple control rooms and production suites. Lounges and proper bathroom facilities are important in keeping the creativity flowing. A dining area and kitchen are also a consideration if budgets permit. Many hours are spent in the studio when working on projects. It is important to have all the comforts of home to keep everyone happy.

A few proper offices are necessary for the client to be able to have private internet access and to handle business without any distractions. All studios are designed differently. Whatever can be imagined can be created. There are no rules, only guidelines.

Acoustics

Sound is a wave, much like the ripples on a still body of water when a rock is dropped into it. The larger the wave, the lower the tone. Lower tones, known as bass frequencies, travel in wide long waves while higher tones known as treble frequencies travel in a tighter, shorter wave. Frequencies heard by the human ear range from 20Hz to 20K. Just as an indication, a piano's range, probably the widest range of any instrument, is from 39Hz on the low note and 3Khz on the high note.

Sound is measured in decibels also represented as dB. An average concert is about 95-100 dB while a heavy rock concert or hip hop concert could reach levels of 130dB. This is above the threshold of pain; so don't forget to wear your earplugs which are designed to protect your hearing when in extreme sound levels. Interestingly enough, whales can actually produce levels of up to 180dB. It should be remembered that taking care of your ears is the most important thing you can do to prevent damage and have a sustained career. So don't hang out with any whales and put some protection in your ears when exposed to loud volumes.

Absorption is the act of a sound wave being soaked up by a particular material. This is measured by co-efficient ratings. The higher the sound absorption co-efficient rating, the more sound that is being eliminated from troubled spots in your room. Different section of the room may require different co-efficient ratings. Remember that studios start off as an empty shell. Hard surfaces and walls need treatment to provide for a great sounding room. For example, 20 gauge theater curtains are commonly used in studios. They consist of a thick velvet material, which is excellent for absorbing high-end frequencies. The thinner materials soak up higher frequencies.

The thicker materials soak up lower frequencies. This is why thick bass traps are very large and contain ports or holes to trap low-end frequencies. The larger the port, the lower the frequency absorption.

There are endless amounts of products and designs that are used in the industry. Wall panels are also commonly used to absorb sound. These are made from a fiberglass product wrapped in a cloth material. Various sizes and thickness are used for problem frequencies. Again the thin materials eliminate high end and thicker materials absorb low end.

Reflection is the opposite of absorption. Think of the sound as a wave hitting a mirror and bouncing back. This can be used as an advantage for a brighter tone. If a room has too much absorption causing the room to sound too dead, hard surfaces such as wood panels can be placed in strategic locations to add a more live sound to the room.

Some studios have reversible hanging panels that can be flipped between reflective and absorptive to change the room sound at will. For vocals the room may need a more dead sounding absorptive room. Drums may require a more live sounding room. John Bonham, from Led Zeppelin had an amazingly huge live reflective drum sound. This became the goal for the big Rock drum sound.

Prince is underestimated as a drummer. He has a great tight drum sound on his first record where he played all of the instruments as well as the drums. The drums have just the opposite effect using absorption in a small tight room creating a very in your face heavy Pop drum sound.

These are not rules, only guidelines. Using your ears is always the key to getting the best sound.

Designing a studio is quite an undertaking to do professionally. Each room is completely separated and isolated from one another. The most common method is to actually build a room inside of a room. The inner walls do not touch the outer walls, which creates an air gap that traps sound. Each wall can be many feet thick and multiple layers of thick glass and doors divide the rooms.

The floors in each room are floated from the ground with spacers that also create an air space to lower vibrations and help to trap unwanted sound leakage. All floors have different characteristics in the way sound waves bounce off from their surfaces. While wood floors have a warm tone, concrete and tile have a brighter tone. This also holds true for walls.

A solid plan is needed to run cabling between rooms so that each room can be interconnected with each other for microphone signal lines and headphone communication systems. Custom made cable troughs or PVC tubing is used to send groups of microphone cables from a panel to the control room. From the control room the Headphone lines would be run through the walls for communication between all of the rooms.

Materials and Tools

Drywall is needed for walls. The more layers of drywall added will increase the thickness of the studio walls. By using varying thicknesses of drywall stacked and shifted, alternating at the seams will help minimize sound transmission between rooms. Many drywall screws and a good electric drill will definitely come in handy if you are building a studio.

Fabric is used for making wall panels and ceiling clouds that control the absorption in the studio. There are specific fabrics that are designed for different frequency absorption. Each thickness and texture has varying co-efficient ratings at multiple frequency bands.

AC Duct Board and other fiberglass products are wrapped in fabric with spray glue to create absorbing panels called Wall Boxes and Bass Traps. Thermal Fiber or Fiberglass Insulation is inserted in between two sets of walls and ceiling to create an additional thickness providing an alternate texture, containing fiberglass, which is superb for capturing sound.

Sand is also an excellent alternative choice for filling walls to prevent sound wave transmission. Wood provides the skeleton for frames that hold the panels and boxes. Larger Bass Traps with large ports could be made from wood or fiberglass. RPG panels are a series of wooden slats mathematically designed to absorb and refract, or soak up and scatter sound inside a room. Wood can also be used to create custom racks to hold the outboard gear, console and patchbay. Custom studios can be designed for any situation and style.

Doors, Walls and Windows

Doors and walls are the single most important item where recording studio sound bleed is concerned. A small 1/4inch air gap at the bottom threshold of a door will release 30% of the sound. Creating airtight rooms are the first step in sealing all the gaps for optimum sound proofing. The transitions between where the rooms are connected have more possibilities for sound leakage. All corners, gaps and frames for door and window cutaways must be sealed with a silicon or caulking material. Keep in mind that if air can escape through any passage then sound will surely go through as well.
