Title:
VEHICULAR AIR CONDITIONER
Document Type and Number:
WIPO Patent Application WO/2019/021710
Kind Code:
A1
Abstract:
Provided is a vehicular air conditioner capable of heating a passenger compartment with heat of a battery and preventing deterioration of heating performance due to a decrease in circulating refrigerant. The air conditioner comprises a battery temperature adjusting device 61 for adjusting the temperature of a battery 55 mounted on the vehicle by circulating a heat medium. The battery temperature adjusting device 61 has a refrigerant-heat medium heat exchanger 64 for exchanging heat between the refrigerant and the heat medium, and includes a check valve 30 that returns the refrigerant discharged from the refrigerant-heat medium heat exchanger 64 to the suction side of a compressor 2 and that blocks the flow of the refrigerant from the refrigerant-heat medium heat exchanger 64 toward an outdoor heat exchanger 7 and a heat absorber 9.
