4 MAIN COMPONENTS OF AN AIR CONDITIONER

The vapor compression refrigeration system is made of:the compressorthe condenserthe metering device (the expansion device)the evaporator

TheCompressoris the heart of the system. It is responsible for pumping the refrigerant into the system. Refrigerant enters the compressor as a low pressure/low temperature vapor, and leaves the compressor as a high pressure/high temperature vapor. Then it goes to the condenser.

TheCondenseris the system component responsible for rejecting heat from the system. It's actually a heat exchange in which the refrigerant condenses/turns into a liquid. Condensers are always fed through the top. It rejects heat by removing it from the system and displacing it outside (or away from a desired area). The refrigerant then travels to a metering device as a high temperature/high pressure liquid.

TheMetering Devicecontrols the flow of refrigerant to the evaporator, and changes the pressure of the refrigerant fromHIGHtoLOW. Then the low pressure/low temperature refrigerant (liquid) goes to the evaporator.

TheEvaporatorabsorbs heat from the space that's being cooled, and is always fed through the bottom. As the refrigerant flows through the evaporator, the refrigerant changes from a liquid to a vapor as it absorbs heat from the space. As the refrigerant vaporizes, it becomes a low temperature/low pressure vapor that is carried back to the compressor to start the cycle over and it continues to repeat.
