What is the role/use of compressor in the working of air conditioners?

the compressor is used to compress cold air to be used in the cooling process of a/c. you lose very little coolant in the production of a/c.it takes the humidity out of the surrounding air and that is why we see the outside of the a/c drip water. that is the water or humidity that has been taken out of our environment

Wow some of these answers are scary.  The air conditioner works by taking heat from inside the room and blowing it outside.  If the air conditioner is completely in the room, then all the heat that it blows outside stays in the room, therefore the temperature stays the same.\nBut...\nAll machines create heat just by running.  Think computers, light bulbs, etc.  Therefore, the temperature will get a little higher.

compressor: compresses things\nevaporator: evaporates things\ncondensor: condenses things\nmetering device: meters things\n\ngood luck

<>You have to be more specific.  Are you talking about an electrical condenser, a refrigeration condenser, an air conditioning condenser, or some other kind?

I have a heat pump system for my shop and my wife's craft room. My shop is on the first floor and her room is on the second floor. The HVAC contractor installed one outdoor compressor and one air handler. There are electrically controlled dampers in the supply and return air from each room. There are two thermostats and a microprocessor. The microprocessor controls the dampers and directs the heating (or cooling) to which ever room is calling for it.

Its bound into a CloroFloroCarbons used in the "Freons"\n\nThe Freons are special molicules that are realitivly safe (Unless your an Ozone layer) and have BOILING points below the temprature you want to achieve.  Basicly There is a pump inside a air conditioner that compresses the gas until it becomes liquid where it gives off its heat *feel the back side of an air conditioner* then it goes through a tiny little tube and boils inside the tubes on the front side of the air conditioner *the one on the back is called a condenser, the one on the Front is called a evaporator based on if the freon is condensing or evaporating in it*

The compressor of your Refrigerator is not designed to keep cool a large space such as your room. So once you keep it open, the compressor will get overloaded and it will be spoiled. Take care.

http://en.wikipedia.org/wiki/Air_conditioner#Air_Conditioning_System_Equipment\nAs for the water in the air, you have to remember, that this water is taken out of all the air that is passing through the air conditioner for all the hours it is running.  That's a LOT of air.  Air can hold more water than you think.

For a rotary compressor,air passes through two meshing gears. As the gears rotate, the air passing to it is being compressed.\nFor a reciprocating compressor, the air is compressed in the cylinder by a piston.

I guess you didn't like the answers you got before but that doesn't make them less accurate.\n\nHere is my answer again. It comes from many years of designing, installing and operating compressors of all kinds. Remember, an engineer wants a simple system if possible. A single stage compressor is more desireable if it will do the job but as some point multistate compressors become necessary.\n\nOne of the primary problems that positive displacement air compressors face is high discharge temperatures. The high temperatures can cause or accelerate lubrication problems and valve failures. \n\nIf the compressor is a non lubed version the high temperatures can also contribute to piston ring problems.\n\nBy having multistages, you can intercool the air and reduce the discharge temperature on each stage. In addition to helping with valve, lubrication and piston problems, the required horsepower for a give capacity is reduced.\n\nThe other limit that comes into play for positive displacement piston type compressors is rod load. That is the limiting force that can be placed on a given cylinder on a compressor frame. If the compression ratio is too great, the force exerted by the compressor rod can exceed the capability of the compressor frame and some component will fail. It might be the actual rod or it could be the crank bearings or other components. Typically it is the rod so any failure will not wreck the whole compressor.\n\nThere are many positive displacement air compressors that are multistage. This is specially true in small size units.

I presume you're asking about an air conditioner.\n\nAir conditioners are rated in terms of the equivalent cooling capacity of tons of ice.   So, a one ton air conditioner can cool as much as a ton (2000 lbs) of ice melting in a 24 hour period.   A home air conditioning unit is typically in the range of 1-3 tons of capacity.  One ton is also equivalent to about 12000 BTUs (British Thermal Units) per hour of cooling.

Mechanical engineers research, design and develop machinery and systems for heating, ventilating and air conditioning, power generation, transportation, processing and manufacturing. They also perform duties related to the evaluation, installation, operation and maintenance of mechanical systems. Mechanical engineers are employed by consulting firms, by power-generating utilities and in a wide range of manufacturing, processing and transportation industries, or they may be self-employed

In a rotary air compressor, there is a spinner and the air comes into the middle and gets spun to the outside.  It builds up a velocity as it moves faster and faster toward the circumference of the spinner assembly, until it hits the outer housing and gets squashed as it hits until it escapes thru an outlet tube.  When it squashes, the pressure rises, giving an outlet pressure higher than the inlet pressure, i.e. compressed air.

Theoretically the two answers above are correct, but the actual watts that the aircons consume depends on the temperature settings and the room itself. The aircon (compressor) will stop working after reaching the desired temp.If the room has many things that generate heat (kitchen equipment, lighting, people), then the aircons may have to work overtime. In this case "maybe" the 2.5 hp actually consume less energy because it can cool the room faster, or have to work only every 5 minutes.

Outside the house you have a condenser unit with a compressor.  The compressor compresses freon gas and that makes it hot.  The condensor then removes the heat and turns the freon into liquid.  That is why the outside unit blows out hot air.  The liquid freon then goes to the evaporator inside the house.  In the evaporator, there is a thing called the thermostatic expansion valve or some capillary tubes (very small).  The liquid freon discharges through the TEV or capillary tubes and when it does, it expands in the presence of the suction from the compressor to form a gas.  As it forms a gas it draws heat from its surroundings to do that.  That is why the evaporator gets cold.  The cold freon gas is then sucked through the coils in the evaporator where it draws heat from the air coming across them back into the compressor, where the compressor compresses the cold gas and it gets hot again, and the cycle repeats itself over and over as the unit runs!
