Abstract: There is disclosed a vehicle air conditioner device which is capable of continuing an air conditioning operation also in a case where a disconnection failure occurs in a solenoid valve to change a flow of a refrigerant in each operation mode. Respective solenoid valves 17, 20, 21 and 22 to change the respective operation modes of a vehicle air conditioner device 1 are constituted so that the flow of the refrigerant changes to a cooling mode when all the solenoid valves 17, 20, 21 and 22 are non-energized. The vehicle air conditioner device executes a cooling mode during failure in which a controller adjusts all the solenoid valves 17, 20, 21 and 22 to be non-energized and operates a compressor 2, in a case where the disconnection failure occurs in one of the solenoid valves 17, 20, 21 and 22.

Abstract: In a vehicle air conditioning apparatus, during a cooling operation, and a cooling and dehumidifying operation, a refrigerant flows through an outdoor heat exchanger, flows through a supercooling radiator, and then flows into a radiator to absorb heat. During a heating operation, the refrigerant flows through a heat exchanger and then is sucked into a compressor without passing through the supercooling radiator. During a first heating and dehumidifying operation, the refrigerant flows through another radiator, flows through the supercooling radiator, and then flows into another heat exchanger to absorb heat.
