Title:
REFRIGERATION CYCLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/224418
Kind Code:
A1
Abstract:
A refrigeration cycle device (100) comprises: a compressor (1); a first heat exchanger (3); a second heat exchanger (6); a third heat exchanger (7); a flow passage switching valve (2); a first expansion valve (4A); a second expansion valve (4B); a third expansion valve (4C); a refrigerant container (5); a first check valve (8A); and a second check valve (8B). The flow passage switching valve (2) switches the circulation direction of non‐azeotropic refrigerant mixture between a first circulation direction and a second circulation direction. A first port (Pt1) of the third expansion valve (4C) is connected to the refrigerant container (5) via the third heat exchanger (7). A second port (Pt2) of the third expansion valve (4C) is connected, via the first check valve (8A), to a first flow passage (FP1) between the first heat exchanger (3) and the first expansion valve (4A), and is connected, via the second check valve (8B), a second flow passage (FP2) between the second heat exchanger (6) and the second expansion valve (4B).
