ABSTRACT:
An air conditioner has a controller that controls the operation of a refrigerant circuit that has a compressor, a condenser, an expansion valve or orifice tube, and an evaporator. The condenser receives a compressed refrigerant from the compressor and condenses the refrigerant to either a liquid phase or a saturated liquid-vapor phase. The condensed refrigerant is then passed through the expansion valve or orifice tube to expand the refrigerant and to delivery the refrigerant to the evaporator. The controller is operatively coupled to the compressor to operate the compressor to change an average condenser temperature of the condenser from a first temperature to a second temperature that is lower than the first temperature based on at least one control signal indicative of thermal requirements of a vehicle component influenced by the average condenser temperature of the condenser.
