Title:
REFRIGERATION CYCLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/245789
Kind Code:
A1
Abstract:
In a refrigeration cycle device (1), a refrigerant pipe (31) is connected to a compressor (3), a first heat exchanger (5), an expansion valve (9), a second heat exchanger (11), a heat absorbing section (17), and the compressor (3), in this order. R290 is used as the refrigerant flowing in the refrigerant pipe (31). The heat absorbing section (17) is provided in a portion of the refrigerant pipe (31) between the first heat exchanger (5) or the second heat exchanger (11) as an evaporator, and the compressor (3). The heat absorbing section (17) is arranged so as to contact an electric component (19a). A branching pipe (33) is connected so as to be in parallel with the portion of the refrigerant pipe (31) in which the heat absorbing section (17) is provided. A flow rate adjusting valve (21) is provided in the branching pipe (33).
