調装置。 In a vehicle air conditioner, there is a compressor that compresses working gas, a condenser that receives the working gas compressed by the compressor and liquefies the working gas, and adiabatically expands the gas liquefied by the condenser through an expansion valve. an evaporator, a flow path for circulating the working gas expanded in the evaporator to the compressor, and a control circuit for stopping the compressor in response to low temperature information from a thermistor provided in the evaporator,
In order to prevent the backflow of high-temperature fluid from the compressor to the evaporator via the flow path when the compressor is stopped, a solenoid valve is provided that can be closed by a signal from the control circuit to prevent the backflow. A backflow prevention type air conditioner for vehicles featuring:
