装置。 It is possible to switch between a compression cooling cycle in which refrigerant passes through the compressor, condenser, expansion valve, and evaporator in that order, and a compression heat pump cycle in which the refrigerant passes through the compressor, evaporator, expansion valve, and condenser in that order. In an automotive air conditioner, the cooler cycle is used during normal operation, and a means is provided to detect when the compressor has stopped.
An air conditioner for an automobile, comprising a control means for switching the cooler cycle to a heat pump cycle before stopping the compressor based on a signal from the device, heating the evaporator, and then stopping the compressor.
