Title:
冷凍サイクル装置
Document Type and Number:
Japanese Patent JP6733625
Kind Code:
B2
Abstract:
A refrigeration cycle device (10) includes: a first heat exchange unit (20) that heats a fluid for heat exchange using a high-pressure refrigerant discharged from a compressor (11) as a heat source; a decompression valve (13) that decompresses the refrigerant; a heat medium vaporizer (15) that vaporizes the decompressed refrigerant by causing heat exchange with a low-stage-side heat medium; a heat generation device (34) that is disposed in a low-stage-side heat medium circulation circuit (30) and heats the low-stage-side heat medium; a second heat exchanger (39) that heats the fluid for heat exchange using the low-stage-side heat medium heated by the heat generation device (34) as a heat source; a flow rate adjustment valve (35) that adjusts the flow rate of the low-stage-side heat medium flowing into the heat medium vaporizer (15) and the flow rate of the low-stage-side heat medium flowing into the second heat exchanger (39); and a flow rate control unit (50c) that controls the operation of the flow rate adjustment valve (35).
