摘要： A vehicle air conditioner is capable of selecting and changing an optimum operation mode so that a desirable air conditioning performance can be exerted on conditions such as an environment and a set temperature. A controller changes and executes at least one of a heating mode, a dehumidifying and heating mode, a dehumidifying and cooling mode, and a cooling mode. In the dehumidifying and heating mode, the controller shifts to the dehumidifying and cooling mode on the basis of a situation where heat absorption in a heat absorber (9) runs short or heat radiation in a radiator (4) becomes excessive, and also in this dehumidifying and cooling mode, the controller shifts to the dehumidifying and heating mode on the basis of a situation where the heat radiation in the radiator (4) runs short.

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 in a vehicle interior. The controller controls the compressor 2 on the basis of a radiator target pressure (a target high pressure), and corrects the radiator target pressure (the target high 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.

摘要： There is disclosed a vehicle air conditioner which can effectively eliminate occurrence of excess or lack of an amount of a refrigerant to be circulated in an internal cycle mode. A controller changes and executes a heating mode, a dehumidifying and heating mode, an internal cycle mode, a dehumidifying and cooling mode, and a cooling mode. When an amount of the refrigerant to be circulated is excessively large in the internal cycle mode, a controller executes a refrigerant sealing mode to seal a refrigerant in an outdoor heat exchanger 7, and when the amount of the refrigerant to be circulated is insufficient, the controller executes a refrigerant discharge mode to discharge the refrigerant from the outdoor heat exchanger 7.

摘要： 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.

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.
