調和装置の制御回路。An air conditioner for a vehicle that has a refrigerant circuit consisting of a compressor, a condenser, an expansion valve, an evaporator, etc., and performs pump-down operation by disposing a liquid receiver and a solenoid valve between the condenser and the expansion valve. The device includes: a pressure detection switch that operates by sensing the pressure on the low pressure side of the refrigerant circuit; a thermoswitch that operates by sensing the temperature of a predetermined detection portion; and a solenoid valve that is energized when the thermoswitch is closed. A control circuit for a vehicle air conditioner, comprising an electromagnetic clutch connected to the thermoswitch and the pressure detection switch, and a diode that interrupts energization of the solenoid valve when the pressure detection switch is closed.
