HVAC: Heating & Air-conditioning: Air-conditioning components

Air-conditioning compressors	The compressor circulates refrigerant through the air-conditioning system. Axial piston compressors are one of the most common types used.
Condensers & evaporators	The condenser transfers heat from the refrigerant to the outside air. The evaporator draws heat from air in the passenger compartment.
Receiver drier	The receiver drier acts as a storage volume for liquid refrigerant. It also contains filters and desiccants.
Lines & hoses	Hoses and pipes must be capable of withstanding the high pressures and temperatures that are found in the air-conditioning system.
TX valve construction	The thermal expansion valve controls the amount of refrigerant entering the evaporator coils. It also causes a drop in pressure without causing a change of state.
Temperature monitoring thermostat	The thermostat monitors the temperature of the evaporator fins and controls system operation within set limits.
Refrigerants	The refrigerant is used to absorb, transfer and release heat in the air-conditioning circuit.
Pressure switches	Pressure switches protect the system from excessively high or low pressures.
Heating elements	Most vehicles contain a heated rear window When the rear demister switch is turned on, electrical current flows through the wire causing it to heat.
