Title:
VEHICULAR AIR CONDITIONER
Document Type and Number:
WIPO Patent Application WO/2018/198582
Kind Code:
A1
Abstract:
Provided is a vehicular air conditioner capable of expanding the executable range in a dehumidifying/cooling operation by preventing or suppressing the occurrence of temperature variation in a heat sink during the dehumidifying/cooling operation. After a refrigerant discharged from a compressor (2) dissipates heat in a radiator (4) and an outdoor heat exchanger (7), and the resultant heat-dissipated refrigerant is depressurized, a dehumidifying/cooling operation is executed in which heat is absorbed by a heat sink (9). In the dehumidifying/cooling operation, the compressor is controlled on the basis of the temperature of the heat sink and the valve opening of an outdoor expansion valve (6) is controlled on the basis of the pressure of the radiator. In a case where the heat radiation capability of the radiator is insufficient in the dehumidifying/cooling operation, a shutter (23) is closed.
