ABSTRACT:
In the freezing cycle of an air conditioner for an automotive vehicle, first and second evaporators are connected to the inlet of a compressor. The first evaporator cools air to be blown into the passenger compartment of the vehicle, and the second evaporator, provided in the intake system of the vehicle engine, cools air to be taken into the engine. A pressure control valve is provided at the outlet of the second evaporator for controlling the boiling pressure of the refrigerant therein, or alternatively, the compresser may be of variable displacement type, to thereby prevent the compressor from consuming increased power during high speed operation of the engine.
