Title:
HEAT PUMP CYCLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/157716
Kind Code:
A1
Abstract:
This heat pump cycle device comprises: a compressor (11); a branch portion (12a); a heating unit (13, 30, 131) that heats an object to be heated using one of the refrigerants branched off at the branch portion as a heat source; a heating-side decompression unit (14a, 14b, 14c) that decompresses the refrigerant flowing out of the heating unit; a bypass passage (21c) through which the other refrigerant branched off at the branch portion flows; a bypass-side flow rate adjustment unit (14d); and a merging portion (12f). The inlet-side flow path length L1 is equal to or longer than the relaxation distance Lv, where the inlet-side flow path length L1 is defined as the length of an inlet-side flow path (21d) from the outlet of the merging portion (12f) to the inlet of the compressor (11). The relaxation distance Lv is the flow path length required to bring the refrigerant mixed in the merging portion (12f) into a homogeneous state.
