Title:
REFRIGERATION CYCLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/240729
Kind Code:
A1
Abstract:
This refrigeration cycle device is provided with: a compressor for compressing refrigerant; a first heat exchanger for cooling, with outdoor air, refrigerant that has been compressed by the compressor; a depressurization device for reducing the pressure of the refrigerant; a second heat exchanger for cooling heat medium with refrigerant that has been depressurized by the depressurization device; a third heat exchanger for cooling heat medium with outdoor air; a first heat medium passage for linking a heat medium outlet of the third heat exchanger to a heat medium inlet of the second heat exchanger; a first bypass valve for causing heat medium to flow into a first load device from the first heat medium passage; a second heat medium passage for causing heat medium that has flowed out from the second heat exchanger to flow into a second load device; a second bypass valve for causing heat medium that has flowed out from the second heat exchanger to flow into the first load device; a return passage through which heat medium that has returned from the first load device and heat medium that has returned from the second load device pass; and a flow path switch valve for switching between a first mode whereby heat medium flows into the first heat medium passage from the return passage without passing through the third heat exchanger, and a second mode whereby heat medium flows into the third heat exchanger from the return passage.
