Title:
VEHICLE AIR CONDITIONING DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/137236
Kind Code:
A1
Abstract:
[Problem] To provide a vehicle air conditioning device that reliably cools a device which needs to be cooled and that can ensure a required heat absorption amount in a refrigerant circuit during a heating operation. [Solution] An accumulator 26 includes a heat exchanger 26f that exchanges heat between a refrigerant that circulates through a refrigerant circuit and a heat medium that circulates through a heat medium circuit. This configuration makes it possible to cool a battery connected to the heat medium circuit and to increase the heat absorption amount in the refrigerant circuit during the heating operation. Thus, a battery that requires cooling can be reliably cooled and a heat absorption amount required in the refrigerant circuit during the heat operation can be secured.
