Compressor HVAC: Description and Operation

The compressor's function is to pump refrigerant and refrigerant oil through the A/C system and to compress high-temperature gaseous refrigerant to high-temperature/high-pressure liquid refrigerant. It is the heart of the A/C system and is essentially (with the exception of the condenser fan) its only moving part. The compressor used in this vehicle is a cycling, ten piston Swash plate-type, with a total piston displacement of 82 cc (5 cu. in.).
