調装置。[Claims for Utility Model Registration] 1. A cooling cycle that is connected to an engine via an electromagnetic clutch and includes a compressor and an evaporator that evaporates refrigerant; a capacity variable device that changes the capacity of the compressor into at least two stages; It comprises an evaporation pressure adjustment device that adjusts the evaporation pressure of the evaporator in at least two stages, and a thermoswitch that controls the operation of the evaporation pressure adjustment device and the capacity variable device based on the output from the heat load detector. The thermoswitch switches the compressor to a small capacity when the heat load becomes equal to or less than a first set value, and switches the compressor to a small capacity when the heat load becomes equal to or less than a second set value, which is lower than the first set value. An air conditioner for an automobile, characterized in that the evaporation pressure of an evaporator is limited to a predetermined value or more. 2. The evaporation pressure regulating device is composed of a low pressure regulating valve inserted between the compressor and the evaporator of the cooling cycle, a bypass passage that bypasses this low pressure regulating valve, and a solenoid valve provided in this bypass passage. An air conditioner for an automobile according to claim 1, which is characterized in that:
