Abstract:
The present invention provides a compressor for refrigeration and air conditioning and a refrigeration and air conditioning device, which are capable of achieving both good environmental performance and good refrigeration cycle efficiency. This compressor for refrigeration and air conditioning has a refrigerating machine oil made from polyolester and a difluoromethane-containing refrigerant which are sealed therein. The polyolester has, as a structural unit, poly[2,2-di(alkanoiloxymethyl)oxytrimethylene] having two or more repeating units. Furthermore, the polyolester comprises one or both of a cyclic polyolester obtained by cyclopolymerizing molecular chains having said structural unit and a crosslinked polyolester obtained by crosslinking molecular chains having said structural unit through a structural unit to be crosslinked that is polymerized with said structural unit.
