Abstract: There is disclosed a vehicle air-conditioning device in which a heating qualification by gas injection can sufficiently be obtained. The vehicle air-conditioning device comprises a compressor 2 which compresses a refrigerant, an air flow passage 3 through which air to be supplied into a vehicle interior flows, a radiator 4 disposed in the air flow passage to let the refrigerant radiate heat, a heat absorber 9 disposed in the air flow passage to let the refrigerant absorb heat, an outdoor heat exchanger 7 disposed outside the vehicle interior to let the refrigerant radiate or absorb heat, and a controller. The controller executes a heating mode in which the refrigerant discharged from the compressor 2 radiates heat in the radiator 4 and the refrigerant by which heat has been radiated is decompressed and then absorbs heat in the outdoor heat exchanger 7. The vehicle air-conditioning device comprises an injection circuit 40 which distributes a part of the refrigerant flowing out from the radiator 4 to return the refrigerant to the middle of compression by the compressor 2, and the injection circuit 40 has an expansion valve 30, and a discharge side heat exchanger 35 which performs heat exchange between the refrigerant decompressed by the expansion valve 30 and the refrigerant discharged from the compressor 2 before flowing into the radiator 4.

Abstract: There is provided a vehicle air conditioning apparatus that can prevent the amount of the refrigerant discharged from the compressor from reducing when an outside air temperature is low to achieve a heating performance required for a heating operation, and also can dehumidify the vehicle interior without deteriorating the heating performance during a heating and dehumidifying operation. The vehicle air conditioning apparatus includes: a heat released refrigerant expansion valve that decompresses the refrigerant discharged from the radiator during the heating operation and the first heating and dehumidifying operation; a gas-liquid separator that separates the refrigerant decompressed by the heat released refrigerant expansion valve into a gaseous refrigerant and a liquid refrigerant; and a bypass circuit that allows part of at least the gaseous refrigerant separated in the gas-liquid separator to flow into a section of the compressor through which the refrigerant being decompressed passes.

Abstract: There is disclosed a vehicular air conditioner in which in a dehumidifying and cooling mode, a heating capability of a radiator can be acquired without increasing a flow rate of a refrigerant into a heat absorber. The dehumidifying and cooling mode is executed to let the refrigerant discharged from a compressor 2 radiate heat in a radiator 4 and an outdoor heat exchanger 7, decompress the refrigerant by which heat has been radiated and then let the refrigerant absorb heat in a heat absorber 9. The vehicular air conditioner includes an injection circuit 40 which distributes a part of the refrigerant flowing out from the radiator 4 to return the part of the refrigerant to the compressor 2, and in the dehumidifying and cooling mode, the injection circuit 40 is operated to return the refrigerant to the compressor 2, in a case where there is established predetermined radiator capability shortage condition on which a heating capability of the radiator 4 runs short and/or predetermined low outdoor air temperature startup condition on which startup is performed at a low outdoor air temperature.

Abstract: There is disclosed a vehicle air conditioner device which is capable of continuing air conditioning of a vehicle interior also in a case where a failure occurs in a solenoid valve to change a flow of a refrigerant in each operation mode. A vehicle air conditioner device 1 includes a solenoid valve 17 for cooling, a solenoid valve 21 for heating and a solenoid valve 22 for dehumidifying to switch respective operation modes of the vehicle air conditioner device. A controller changes and executes the respective operation modes of a heating mode, a dehumidifying mode, and a cooling mode. The controller has a predetermined air conditioning mode during failure, and failure detecting means for detecting failure of the solenoid valve. In a case where the failure detecting means detects that the solenoid valves fail in the respective operation modes, the controller selects the air conditioning mode during failure in which vehicle interior air conditioning by the operation mode is achievable, to continue the air conditioning of the vehicle interior.
