Title:
AIR-CONDITIONING DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/162864
Kind Code:
A1
Abstract:
This air-conditioning device comprises: a refrigerant circuit that has a compressor, a flow path switching device, a heat source side heat exchanger, at least one intermediate heat exchanger, and an expansion device corresponding to each of the intermediate heat exchangers, and circulates a refrigerant between the compressor, the heat source side heat exchanger and the at least one intermediate heat exchanger; a heat medium circuit that has at least one intermediate heat exchanger, a pump corresponding to each of the intermediate heat exchangers, and a plurality of user-side heat exchangers, and circulates a heat medium between the at least one intermediate heat exchanger and at least one of the plurality of user-side heat exchangers; and an auxiliary circuit that is connected to the heat medium circuit and has an auxiliary heat exchanger. The auxiliary heat exchanger heats or cools the heat medium flowing into the auxiliary circuit, by heat exchange with a secondary heat medium.
