Document Type and Number:
WIPO Patent Application WO/2018/139342
Kind Code:
A8
Abstract:
Provided is a vehicle air-conditioning apparatus which can achieve comfortable air-conditioning of the passenger compartment by expanding the effective range of a dehumidifying heating mode. A controller executes a dehumidifying heating mode in which a refrigerant discharged from a compressor 2 radiates heat through a radiator 4, with some of the refrigerant flowing into an indoor expansion valve 8 from a bypass circuit (refrigerant pipe 13F) and the rest flowing to an outdoor expansion valve 6. In the dehumidifying heating mode, which has a state in which the operation of the compressor 2 is controlled on the basis of a heat sink temperature Te, a radiator temperature priority mode for increasing the capacity of the compressor is executed if radiation from the radiator is insufficient.
