Title:
COMPRESSOR AND REFRIGERATION CYCLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/071028
Kind Code:
A1
Abstract:
With respect to a compressor and a refrigeration cycle device that use a refrigerant containing a hydrofluoroolefin, the problem to be solved by the present disclosure is to suppress corrosion of the compressor. A compressor (30) is the compressor (30) of a refrigeration cycle device (20) that uses a refrigerant containing a hydrofluoroolefin and that performs a refrigeration cycle using a freezer oil containing a polyol ester or a polyvinyl ether. The compressor (30) comprises a sliding section (79s). The sliding section (79s) is formed from an aluminum alloy that includes 5–25 wt% of silicon. The freezer oil includes an acid capture agent or an oxygen capture agent and fulfills the formula: Total content of acid capture agent and oxygen capture agent in freezer oil [wt%] ≥ 2.3 + 2.6 × (hydrofluoroolefin content in refrigerant [wt%]) − 1.6 × (silicon content in sliding section [wt%]).
