Title:
REFRIGERATION CYCLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/026532
Kind Code:
A1
Abstract:
This refrigeration cycle device has a compressor (11), a heat dissipator (12) for heating, a heat dissipator (13) for a heat medium, a decompressor (14), an evaporator (15, 73), and a dissipated heat amount adjuster (44, 18). The heat dissipator for heating causes the heat of a high-pressure refrigerant to be dissipated to a heat-exchanging fluid. The heat dissipator for a heat medium causes the heat of the high-pressure refrigerant to be dissipated to a high-temperature-side heat medium. The decompressor decompresses refrigerant that is downstream from the heat dissipator for heating and the heat dissipator for a heat medium. The evaporator causes the refrigerant decompressed in the decompressor to evaporate by absorbing the heat of the heat-exchanging fluid. The dissipated heat amount adjuster adjusts the amount of heat dissipated from the high-pressure refrigerant to the heat-exchanging fluid in the heat dissipator for heating. In a heating mode for heating the heat-exchanging fluid, the dissipated heat amount adjuster increases the dissipated heat amount in the heat dissipator for heating so as to be greater than in the dissipated heat amount in the heat dissipator for a heat medium. In a cooling mode for cooling the heat-exchanging fluid, the dissipated heat amount adjuster reduces the dissipated heat amount in the heat dissipator for heating so as to be less than that of the heating mode.
