Document Type and Number:
WIPO Patent Application WO/2020/050022
Kind Code:
A1
Abstract:
The purpose of the present invention is to suppress the degradation of a refrigerator oil when using trifluoroiodomethane (CF3I) as a refrigerant. This electric compressor 3 is provided with a compression mechanism part 33 for compressing a refrigerant; an electric motor 24 that drives the compression mechanism part 33 via a crankshaft 23; and a main bearing 31 and a sub-bearing 32 that pivotally support the crankshaft 23. A refrigerator oil 29 is stored in the bottom part of a sealed container 25. Trifluoroiodomethane (CF3I) by itself, or a refrigerant mixture of trifluoroiodomethane (CF3I) and another refrigerant is used as the refrigerant. The refrigerator oil 29 is mixed with an acid capturing agent. The saturated moisture content of the refrigerator oil 29 mixed with the acid capturing agent is higher than the saturated moisture content of the refrigerant.
