Beschreibung
Zusammenfassung:	A refrigeration cycle apparatus including, a compressor, a condenser, a pressure reducer, and an evaporator that evaporates the refrigerant. The refrigerant is a mixed refrigerant which contains refrigerant components of difluoromethane, pentafluoroethane and trifluoroiodomethane and which has a global warming potential and a specific vapor pressure. The compressor is a sealed electric compressor which includes a compression mechanism and a motor to drive this compression mechanism, and which is charged with a refrigerator oil to lubricate a sliding portion, and the refrigerator oil is polyvinyl ether oil, and contains 0.1% by mass to 2.0% by mass of a stabilizer constituted by at least one of an alicyclic epoxy compound and a monoterpene compound, 0.1% by mass to 2.0% by mass of an acid scavenger constituted by an aliphatic epoxy compound, and 0.1% by mass to 2.0% by mass of an extreme pressure agent constituted by tertiary phosphate.
