Abstract
A vehicle air conditioning device which is capable of inhibiting liquid return to a compressor and generation of noise due to bumping in an accumulator. There are executed a heating mode to close a solenoid valve, open a solenoid valve, let a refrigerant from a compressorradiate heat in a radiator, decompress the refrigerant through an outdoor expansion valve, let the refrigerant absorb heat in an outdoor heat exchanger, and send the refrigerant to an accumulator, and a dehumidifying and cooling mode to open the solenoid valve, close the solenoid valve, decompress the refrigerant through an indoor expansion valve, let the refrigerant absorb heat in a heat absorber, and send the refrigerant to the accumulator. When shifting from the heating mode to the dehumidifying and cooling mode, the solenoid valveis opened for a predetermined period of time.
