How many types of ducts in air conditioning system?
It varies for each home. A manual J, D, & S should be performed to determine the amount/size of ductwork that is needed.

Answer over simplified but very usable . Hi:. Here is a simplified breakdown for your question. I can get way more specific and into way more detail (but) if you ask someone what time it is,,, do you really want them to teach you how to build a clock?. 1... Assuming the application design crite…ria is for say ( an average home ) and you have pretty much . establish the type and tonnage of the system you require to be fairly accurate then we can go one step further. Homes, Businesses, Churches, and in general a multitude of applications basically have basic design rules that vary from one to another. A important factor would be the speed of the air flowing through the ducts, vents, and returns. Air can get pretty loud rushing through a pipe or into a pipe via some form of vent or return. In general Churches require a very quiet air flow design and homes also need to be quiet though not necessarily as quiet as a church. Of course, a bowling alley or bar with loud bands and such,,, ( well,,, not so quiet required ) Now you may be wondering ,,, hmmmmmmmmmmmm????? ,,,, soooooo,,, how do I get easy hands on and in general duct design sizes along with vent and return sizes for my application. The answer is fairly simple believe it or not. Use a factory design guide usually available from where you purchase your equipment. Kewl Huh !!! The return air grill or filter grill is basically like this,,, ( larger is better). Of course,,, within reason. Filters do a better job if the air flowing through them is at a slower rate of speed. ( Makes sense huh ! ) So, larger area will give you reduced air speed and not surprisingly quieter operation. So,,, look up the criteria that your unit has as to how many cubic feet a minute of air flow it is designed to work well at. Then take into account some area's or rooms simply will require % wise air flow than others to be comfy in for various factors usually refered to as heat load. common sense will tell you which areas will on average require more of your % of available systems abilities. If your still with me ( wow ) match all this up with your ductwork and grill supplier charts and recommendations for their products and viola!!!! ( Neat huh ? ) Remember,,,, this is a compacted answer,,,, so don't go puttin it under a microscope 10X on me. Honestly though,,, you'll be surprised how well things will work out though..

Exactly what I am doing now. My furnace is old and ineffiecient so I bought a new, ineffiecient furnace. (80%) natuaral gas. I also bought a cooling coil that fits on top (upflow furnace) of the furnace. I bought a condensing unit that will go outside and be wired to the furnace and thermostat and c…onnected to the coil with refriderant lines. All of this was less than half of what an installer quoted for just a new furnace!. The new furnace is the exact dimensions of the old, so it is a plug and play situation. However, I need to have a licensed plumber make the connections, which then need to be inspected by the town. I have an EPA 608 certification to make the AC connections, but that must be inspected as well. I have to run a whole new circuit (220V) to the wall where the outside unit will sit.. So for less than $2,000 I will replace my old junky furnace for a new split system furnace/AC system. I also replaced my old thermostat for a new digital programable thermostat for $49. This should save $ as you can program less heat or cool when everyone is at work. (MORE)
The only reason to flush the ac system is if you had a compressor burn out.. if this did not happen you just need to have the system recharged.. you might have air the the system pull a vaccum on the system this should remove. the air and the moisture.. . If you replace the compressor you should… replace the drier and expansion valve and. flush the system.. To flush it you need a flush solution and clean dry compressed air. Put the solution in. and force it out with the air one line at a time until the flush comes out clean. Install. the new parts with the proper amount of oil and recharge the system. (MORE)
Daikin is the best in air conditioning! I think that geothermal air conditioning is the best! The Department of Energy (DOE) and the Environmental Protection Agency (EPA) have both endorsed Geothermal Heat Pump systems as among the most energy efficient, environmentally clean, and cost effective …systems for temperature control. Plus you can receive a 30% tax credit for purchasing one. More info http://goeggsales.com In my opinion and that of the majority of technicians asked as well as consumer reports, Trane/American Standard is by far the best, the installation is 1/2 the result however, especially in non package units. (MORE)
Yes, this way the ac does not have to run your bill up to cool areas that do not need it.. However, if it is humid and wet in the basement, you should run the air conditioner periodically to recirculate the air and reduce the amount of humidity down there.
There is little the common person can do these days to fix an AC system in a car. With all the environmental regulations, the system must be hooked up to a recovery system, and recharged only by those who have the qualifications (and license sometimes) to do such kind of work.
Maybe you need to rewire the fan speed to the next highest setting on the cooling cycle.
An air conditioning system works in a cycle. One side of the system is considered the high pressure side and the other side is considered the low pressure side. The air condition compressor can be viewed as the center line between these "sides" of the system. Refrigerant R-12 or R-134a (the most com…mon types of refrigerant used in mobile A/C systems) remains at rest in the components an lines of the system until you turn on your A/C. At that point the electromagnetic clutch on the compressor engages and draws refrigerant (in a gas/liquid form) into it to be pumped throughout the system. Upon leaving the compressor the refrigerant has been compressed and thereby heated up resulting in it being transformed into a gaseous state. The refrigerant then travels into the condenser which removes heat from the refrigerant in an effort to return it to a liquid form. From the condenser the refrigerant will often pass through an expansion valve or an orifice (the other component in the system which divides the high an low pressure "sides") where it it "metered" to change it from High pressure on the compressor outlet side to low pressure. After the expansion valve the refrigerant moves into the evaporator. The evaporator is the component that actually removes heat from the air being forced through it by your vehicle's blower fan which pushes "cooled" or "conditioned" air through your vents. From the evaporator, the refrigerant (now mostly in gas form again) travels through a reciever-drier with removes moisture caused by condensation (which may have resulted from the heating and cooling of the refrigerant) before it returns once again to the compressor to repeat the cycle. *Note: . R-12 and R-134A have very low boiling points and can be utilized in a liquid for due to the internal pressure of the A/C system. . R-12 is no longer produced to the CFCs and their environmental impact. . The A/C compressor's electromagnetic clutch is also engaged when using a "defrost" function in most vehicles. . There are high and low pressure sides of the system, the condenser is on the high side and the evaporator is on the low side. Components include: . Compressor . Condenser . Expansion valve/ orifice . Evaporator/ blower motor . Reciever-drier (MORE)
a central air conditioning system contains an indoor unit and outdoor unit. the condenser extracts air from the indoors moves it out and brings cool air through the furnace which then distributes it through ducts in the house. in winter time the furnace works to provide your home with warm air. your… thermostat is the control center for your central A/C system. when the temperature rises passed the set temperature the thermostat tell the rest of the system to kick on and when the set temperature is reach the system shuts of so in simple terms a central air conditioning systems contains a group of components that distribute air through ducts in the home (MORE)

There are three main types of air ducts: sheet metal,pre-insulated, and flexible duct work. Sheet metal air ducts can be made of galvanized steel or aluminum,and may be insulated inside or outside with fiberglass. There are pre-insulated air ducts, which are relatively inexpensiveto install, made o…f fiberglass duct board, polyurethane foampanels, or phenolic foam panels. Air ducts can also be flexible ducts, made of flexible plastic overa wire coil. (MORE)
Could someone supply feedback that has purchased a trane XV95 gas furnace with a XL16i central air conditioning system. about the pros and cons and if they had to change the sizes of their duct work.?
I purchased the XV95 and XL16i with heatpump in early June 2009. So my experience is very limited. The old system's AC had needed a charge for the past 3 years running and this year the service company said that the system had leaked so low that they could put $400 of freon into it and it could all …be gone the next day... so I figured it was toast. While I can't yet speak to the heating... before the new system was installed the old system ran constantly and barely kept up. The new plant (mind you this summer has been one of the coolest ever in Ohio) cycles off and frequently I observe that it's cooling on "stage 1". The house is 19 years old and the duct work did not need to be changed. (MORE)
In the textile industry, AC has a positive effect on both the yarns used in the textile machine, and the machine itself. It reduces humidity levels so the yarns don't absorb the very moisture out of the air as the yarns are dry. Yarns may also absorb the oils from the skin making the workers hands v…ery dry. As for temperature, the machine will run more efficiently in cooler temps as heat will cause the moving parts to expand and friction will result. Too much expansion of certain parts will throw these parts "off" causing imperfections in the fabric. (MORE)
It is a violation of Federal law to do this yourself if you have not taken and passed EPA CFR 40 certification for the handling of CFC refrigerants.
Have them cleaned if you are so inclined, but otherwise nothing other than checking to make sure there are no air leaks and that if any ducts are located in an unconditioned space such as an attic that the insulation is sound with no tears or loose seams so as to prevent condensation from forming on… the exposed surface of the duct and dripping water into your home. Also check that the units condensate drain is clear and that the pump (if you have one) works properly, (MORE)
You should have that done by a technician. It is illegal to charge a system without repairing leaks, and it is clear that you don't know how to do that.
Because there is a transfer of heat through the evaporator coils inside the conditioned air box inside the vehicle, there is a tendency to create condensation on the coils. This condensation is usually channeled off to the out side of the car via a drain path or hose. If the drain path is blocked, t…he moisture could build up inside the conditioned air box and leak. Also if a drain hose has been disconnected, this could also lead to a leak inside the vehicle.. BTW, I have also seen interior fluid (radiator) leaks from the heater coil due to failed coil assy.

What do you do if central air conditioning ducts are not blowing out strong enough to cool upstairs?
There could be a number of problems. Dirty ducts or heat exchanger. Wrong speed on the fan, or turning the wrong way. Plugged filters or vents.
It can, but it's not usually a good idea. It is hard to protect from the weather, and it will heat up from the sun and reduce the efficiency of the installation. Putting it in an attic or crawl space and ventilating the space with a small fan or cross-ventilation is far more efficient.
i dont believe they have one but dont take my word I don't know if it is called an evaporator, but somewhere in the part of the unit that is inside the house are some coils full of coolant and a fan that blows air over the coils . This is where the coolant evaporates and cools the air. The coolant… is then carried outside and compressed to make it give up the heat . (MORE)

Air conditioning can make someone's power bill become higher andthe units can be costly. Though they keep the house cool and thosein it comfortable.
Using a set of a/c gauges put the blue hose on the low side (suction side) and the red hose on the high side (discharge side) and start out by reading the a/c pressures. If system shows to be low then add freon and oil and remember to keep the low side readings between 30 to 40psi and the high …side between 200 to 250psi depending on the outside temperatureâ¦â¦â¦â¦â¦.

The "duct" in an air conditioning and/or heating system is the sheet metal conduit that carries the conditioned air to the perimeter of a structure and back to the HVAC unit. Typically in a residential application it appears as a square or rectangular metal trunk line centrally located on the ceilin…g of a basement, with round metal run outs coming off the top of the trunk line and running towards the perimeter of the house.

The air conditioning system is behind the dash like all other cars. The compressor, however is mounted on the engine, in the rear of the car, with refrigerant lines running up to the evaporator/condensor up front.
It's the little stem inside the spots where you hook on your gauge hoses to. It's just like the little valve inside the valve stems of your tires. They screw in with a special wrench. It's purpose is to keep the refrigerant inside the system until pressed in usually by your gauge hose.
Aside from circulating the refrigerant and PAG oil, it also changesthe refrigerant from a low pressure vapor to a high pressure vapor,thus allowing the superheat to occur, and the heat exchange vitalto the function of the AC system.
It passes heat out of the high pressure high temp vaporized refrigerant so the it becomes a high pressure lower temperature liquid. It passes heat out of the high pressure high temp vaporized refrigerant so the it becomes a high pressure lower temperature liquid.
Air conditioning systems aren't measure in horsepower - they're measured either in BTUs or in tons. To determine this, a specific model of AC system would be needed.
a number of options are available: 1) surface mounted under the roof with them either being visible or boxed in 2) fan-assisted and floor fixed 3) fixed and insulated well to exterior of the roof construction 4) externally to the walls Alternatively, build the roof higher and hide the… ducts that way (MORE)
That depends on what exactly the air conditioning system is. 1995 and newer model year automobiles use R-134a. Most vehicles older than the 1995 model year use R-12 (CFC-12). Household air conditioning units often use R-22.
first have a look at the manufacturer label and record how many Btu per hour is your A/C capacity then devide this number by 12000 Btu per ton the result will give you the tonage per hour of your unit. if on the other hand label is not available or is missing, take the amps drawn by the compressor a…t full load and normal operating conditions devide by 6 and you will get the approximate tonage for your unit ( you should note that this way is only valid for a 220v ,50Hz single phase supply only) (MORE)
Standard A standard air conditioner filter is made of spun fiberglass and have cardboard frames. It is only capable of removing 10 percent of airborne pollutants. Standard air conditioner filters only remove larger particles and do not filter harmful allergens and contaminants very well. You have t…o change these filters every month. Pleated The next type of air conditioner filter is pleated. They are manufactured by folding filter material back and forth and have a larger surface area than standard filters. They are capable of removing 35 to 40 percent of harmful particles in the air. Pleated air conditioner filters are slightly more expensive than standard air conditioner filters and you need to replace them once every three months. Electrostatic An electrostatic air conditioner filter uses filter media that has an electric charge that attracts contaminants. They can have a built-in electrostatic charge, or else create a charge from the air moving through the system. Electrostatic air conditioner filters can remove around 90 percent of particles and cost anywhere from $30 to $100. You only need to replace them once every three months. HEPA Another type of air conditioner filter is HEPA, or High Efficiency Particulate Arresting filter. They are able to trap 99.97% of contaminants including fibers, dust, smoke, and pet dander. They can effectively trap particles 1/300th the width of a human hair. Electronic You can also use an electronic air cleaner in your air conditioner. Although these air cleaners function much like electrostatic filters, they are more effective. They use a fan to trap up to 95 percent of particles in an electrostatic precipitator. These devices are usually recommended if you have allergies. (MORE)

If your referring to balancing the pressure in a central heating/ cooling system, commercial or residential, it just means balancing the pressure so that the air flow coming out of all air ducts is the same. If you look on the condenser, which is the unit that's outside and has a couple of PVC pipes… and an electrical disconnect box, you'll see somewhere on the unit it will have a nameplate rating telling you how much power it needs, what types of gas to charge the system with, etc. on that plate or in the manual, it will say 2400 BTU''s, or whatever BTU's your unit is capable of. BTU stands for British Thermal Unit which is basically a Measurement that gives the energy content of a certain fuel. The BTU's will tell how powerful the unit is, and whoever the HVAC technician is will be familiar with this measurement; the larger the area the more power (BTU) you need. To balance the air duct system, mathematical formulas are used to determine the diameter of certain parts of the system that are to be used, reason for having different diameters of ducts is for the pressure. The biggest size ducts are found at the systems intake ( a hole, big or small, that a big fan motor pushes air into the system, and the smallest ducts are found at the end of the run. Does that give you a rough idea? If something's unclear let me know. Hope this helps Will (MORE)
"Freon" is a trademark of DuPont for their CFC and HFC refrigerants. Thus, if you actually have Freon as manufactured by DuPont, then the replacement would be the same type of refrigerant manufactured by any other manufacturer. For example, if you had a car with an R-12 (CFC-12) air conditioning sys…tem, then you would only replace it with R-12. Same thing if you have a car with an R-134a (HFC-134) system - you can only replace it with R-134a. Never mix refrigerants and never use a refrigerant other than the type specified for your system.

Not to be condescending, but if you're asking this question on Wikianswers, then you're probably in way over your head trying to do this. You haven't specified how in-depth you want to get, either. Are you just trying to replace a component, are you trying to replace the whole electrical system, are… you trying to replace the whole system under the hood, trying to replace both, are you trying to repair something which may not require the entire system to be replaced, etc? There's a whole lot more to it than simply a couple bolts and washers here and there. I'd recommend you seek a professional for this. (MORE)
The evaporator transforms the refrigerant from a liquid state to a gaseous state, and also causes it to absorb heat drawn from the vehicle's passenger compartment and transfer that heat to the outside air.
The compressor will not kick on or if it does, the low pressure return line ices up. Some refill cans come with an attached pressure gauge. They are usually under $20, and if you are undercharged, you can fill it. Get one and it will take the guessing out of the troubleshooting.
You can install ducted air conditioning in your home by firstly installing the ductal air systems in your home. After that, you can install the conditioning units on the outside, in order for your environment to be fully conditioned.
In an Air conditioning unit, the evaporator is what is used to cool the air before it is blown out into the surrounding environment. It uses liquid refrigerant which is at a much lower pressure then the surrounding air and sucks the heat out of the air, thereby cooling it ready to be blown out.
In order to make the choice between ducted air conditioning and a split system air-conditioning, one would need to do some research and read up reviews form the sides to make a decision that is best for them, their pocket and their location.
A manual air conditioning system is one where you can turn it off and on when you want and control the temperature at which it is set.
You will want to use the low pressure side, cap is marked with an L
If you want a full, in-depth answer explaining the variouscomponents, how pressure switches work, various compressor types,etc., I'd recommend you take either some HVAC courses or anautomotive air conditioning course.. your local community collegemight offer them, plus they can give you what you nee…d to take thetests and get certified to where you can buy the 30 lb. cylinders,rather than those dinky little 12 oz. cans... what I'm going togive you is a very basic nickel tour. The compressor pushes the refrigerant through the system. At thesame time, heat and humidity is drawn out of the compartment beingcooled.. could be the passenger compartment of a car or piece ofmachinery, could be a room in a building, could be the inside of arefrigerator... it all works the same way. When the refrigerantreaches the evaporator, that heat from the compartment being cooledis drawn to the refrigerant, as heat flows to a colder object. Therefrigerant absorbs that heat, then gets cycled back to thecompressor. It becomes pressurized, undergoes a superheat, thenundergoes an extremely rapid cooling cycle when it gets to thecondenser, and that superheated refrigerant transfers its heat tothe much cooler ambient air flowing through the condenser fins.Then the now much cooler refrigerant cycles back through to theevaporator, and a fan blows across it, delivering cool air throughthe HVAC system.
