Title:
VEHICLE AIR-CONDITIONING APPARATUS
Document Type and Number:
WIPO Patent Application WO/2018/110212
Kind Code:
A1
Abstract:
The present invention eliminates or suppresses temperature distribution (variation in temperature) generated in a heat absorber in a dehumidification cooling mode. The dehumidification cooling mode is executed in which the heat of a refrigerant discharged from a compressor 2 is dissipated at a heat dissipator 4 and an outdoor heat exchanger 7, the pressure of the heat-dissipated refrigerant is reduced by an indoor expansion valve 8, and then the heat is absorbed by a heat absorber 9. A control device controls the performance of the compressor on the basis of the temperature of the heat absorber, and controls the valve opening degree of an outdoor expansion valve on the basis of the temperature or pressure of the heat dissipator. The minimum opening degree of the outdoor expansion valve is changed so that no temperature distribution is generated in the heat absorber or the temperature distribution becomes small.
