ABSTRACT:
An automotive air tempering apparatus for use in an automotive vehicle having a duct through which air is directed into a passenger compartment. The apparatus comprises an air chilling unit including an evaporator provided in the duct and a compressor having a displacement variable for supplying a controlled amount of refrigerant to the evaporator for chilling the air in the duct. A control unit controls the displacement of the compressor to bring the refrigerant temperature to a target value when air is introduced into the duct from the atmosphere. The control unit controls the displacement of the compressor to bring the chilled air temperature to a target value when air is introduced into the duct from the passenger compartment.
