Title:
REFRIGERATION CYCLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/009565
Kind Code:
A1
Abstract:
This refrigeration cycle device comprises a refrigeration cycle formed by connecting, with refrigerant piping, a compressor (10), a first heat exchanger (12), a throttling device (16), and a second heat exchanger (15). Filling the refrigeration cycle is a refrigerant containing a substance which is susceptible to a disproportionation reaction, and either the first heat exchanger (12) and/or the second heat exchanger (15) is provided with a heat transfer pipe (43) having a plurality of flow paths and path-number changing sections (45) that split each of the plurality of multiple flow paths midway from one flow path into multiple flow paths when either the first heat exchanger (12) or the second heat exchanger (15) acts as an evaporator. Each path-number changing section (45) has a face (T) against which inflowing refrigerant impacts and flow paths (X1, X2) whereto the refrigerant impacting the face (T) is distributed, and the face (T) is formed into a predetermined curvature.
