Title:
REFRIGERATION CYCLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/198611
Kind Code:
A1
Abstract:
A refrigeration cycle device comprises a compressor (11), an outdoor heat exchanger (12), a branching unit (14), a pressure reducing unit (15) for cooling air, a heat exchanger (16) for cooling air, a pressure reducing unit (18) for cooling batteries, a heat exchanger (19) for cooling batteries, a pressure regulating unit (20), and a merging unit (21). The outdoor heat exchanger causes refrigerant discharged from the compressor to undergo heat exchange with outdoor air. The branching unit divides the flow of refrigerant that has undergone heat exchange in the outdoor heat exchanger. One division of the refrigerant resulting from division by the branching unit is cooled by the heat exchanger for cooling air after the pressure thereof has been reduced with the pressure reducing unit for cooling air. The heat exchanger for cooling batteries is in contact with a battery (1) so as to be able to conduct heat and cools the battery by causing the other division of the refrigerant, which has had the pressure reduced by the pressure reducing unit for cooling batteries after division by the branching unit, to undergo heat exchange with the battery. The pressure regulating unit reduces the pressure of the refrigerant that has undergone heat exchange with at least a portion of the heat exchanger for cooling batteries. The merging unit merges the refrigerant that has undergone heat exchange in the heat exchanger for cooling air and the refrigerant that has had the pressure reduced by the pressure regulating unit.
