摘要： There is disclosed a vehicle air conditioner in which a refrigerant subcool degree of a radiator to satisfy both a high pressure and a refrigerant flow rate during heating can appropriately be controlled to achieve improvement of a heating capability. The vehicle air conditioner comprises a compressor 2 which compresses a refrigerant, a radiator 4 which lets the refrigerant radiate 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 to let the refrigerant discharged from the compressor 2 radiate heat in the radiator 4, decompress the refrigerant by which heat has been radiated and then absorb heat in the outdoor heat exchanger 7. The controller 32 has a high pressure priority mode to increase a target radiator subcool degree TGSC of the radiator 4 in a direction in which the high pressure is set to a predetermined high value, and a revolution number priority mode to decrease the target radiator subcool degree of the radiator in a direction in which the revolution number of the compressor 2 is set to a predetermined high value.

摘要： There is disclosed a vehicle air conditioner capable of preventing or inhibiting deterioration of a vehicle interior heating capability which is caused by frost formation to an outdoor heat exchanger. The vehicle air conditioner includes a compressor 2, an air flow passage 3, a radiator 4, a heat absorber 9, and an outdoor heat exchanger 7, and executes a heating mode in which a refrigerant discharged from the compressor radiates heat in the radiator, is decompressed and then absorbs heat in the outdoor heat exchanger. The vehicle air conditioner includes an accumulator 12 disposed on a suction side of the compressor, and a bypass circuit 24B disposed from a refrigerant outlet side of the radiator to an inlet side of the accumulator. A controller has a mode in which the refrigerant flowing out from the radiator is passed through the bypass circuit, does not flow through the outdoor heat exchanger, but flows into the accumulator.

摘要： There is disclosed a vehicle air conditioner which can realize a desirable outlet temperature even when a refrigerant subcool degree of a radiator varies. A controller executes a heating mode to let a refrigerant discharged from a compressor 2 radiate heat in a radiator 4, decompress the refrigerant by which heat has been radiated, and then let the refrigerant absorb heat in an outdoor heat exchanger 7, thereby heating the vehicle interior. The controller controls the compressor 2 on the basis of a radiator target pressure, and corrects the radiator target pressure in such a direction as to heighten when a target subcool degree enlarges, on the basis of the target subcool degree (the refrigerant subcool degree) of the radiator 4.
