Air Conditioning: Overview





Air Conditioning

OVERVIEW
The A/C (air conditioning) system transfers heat from the passenger compartment to the outside atmosphere to provide the heater assembly with dehumidified cold air. It is a sealed, closed loop system filled with a charge weight of R134a refrigerant as the heat transfer medium. Oil is added to the refrigerant to lubricate the internal components of the A/C (air conditioning) compressor.
