Air Conditioner Parts
The three main parts of an air conditioner are the condenser, evaporator and compressor.
Refrigerant enters an air conditioner compressor as a low-pressure gas and decreases in size so the fluid molecules will compact and increase in energy and temperature. The refrigerant then leaves the compressor and enters the condenser, which cools it and changes it to a high-pressure liquid to cool the air that enters your home or car.
There are pistons inside a compressor motor, which move up and down. Refrigerant is drawn into the compressor on the down strokes and compresses on the up strokes.
Compressing a gas causes its temperature to rise. The refrigerant enters an air conditioner compressor at a low temperature and moves to the exiting side of the compressor at a higher temperature before it enters the condenser.
A compressor removes vapor from the evaporator, which will draw the humidity out of the air before it blows into your home or car.
