Abstract
A vehicle air conditioner has a bypass pipe which passes a radiator, an outdoor expansion valve, and opening/closing valves. A controller is configured to execute a heating mode to open a first solenoid valve and close a second solenoid valve, and a dehumidifying and heating mode to close the first solenoid valve, open the second solenoid valve, let a refrigerant radiate heat in an outdoor heat exchanger, let the refrigerant absorb heat in a heat absorber, and generate heat in an auxiliary heater. When changing from the heating mode to the dehumidifying and heating mode, the controller sends the refrigerant to a receiver drier, controls a compressor to reduce a difference between pressures before and after the second solenoid valve, opens the second solenoid valve, closes the first solenoid valve, shuts off the outdoor expansion valve, and shifts the compressor to control in the dehumidifying and heating mode.
