Title:
VEHICLE AIR-CONDITIONING DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/140210
Kind Code:
A1
Abstract:
The present invention carries out heating of the inside of a cabin and heating of a battery at the same time while also carrying out optimal temperature control of the temperature of the inside of the cabin and the temperature of the battery. Provided is a vehicle air-conditioning device comprising: a refrigerant circuit R including a compressor 2 that compresses a refrigerant, an indoor heat exchanger 4 that exchanges heat between the refrigerant and air to be supplied to the inside of the cabin, an outdoor heat exchanger 7 that exchanges heat between the refrigerant and outside air, and a temperature-control-object heat exchanger 64; a heat medium circuit 60 through which a heat medium that passes through the temperature-control-object heat exchanger to exchange heat with the refrigerant circulates and which uses the heat medium flowing through the temperature-control-object heat exchanger to adjust the temperature of a temperature control object mounted to the vehicle; and a control device 100 that controls the refrigerant circuit and the heat medium circuit, the refrigerant circuit includes a hot gas circuit that causes the refrigerant discharged from the compressor to bypass the outdoor heat exchanger and to flow to a suction side of the compressor through the indoor heat exchanger and the temperature-control-object heat exchanger, and the control device is capable of executing a hot gas mode in which the refrigerant is communicated to the hot gas circuit to heat the inside of the cabin and to heat the temperature control object with the heat of the refrigerant compressed by the compressor.
