Abstract
A refrigeration cycle apparatus includes refrigerant circuits in which a high pressure shell compressor, an outdoor heat exchanger, an expansion valve, and an indoor heat exchanger are connected; a mixed refrigerant made up of a mixture of 1,1,2-trifluoroethylene, difluoromethane, and 2,3,3,3-tetrafluoropropene and configured to circulate through the refrigerant circuits, the mixed refrigerant containing less than 50 wt % of 1,2,2-trifluoroetylene and a mixing ratio of difluoromethane being between 0.7 times and two times (both inclusive) that of 1,2,2-trifluoroetylene in terms of weight ratio, in a state before the mixed refrigerant is enclosed in the refrigerant circuits; and a refrigerating machine oil enclosed in the refrigerant circuits and prepared such that difluoromethane is least soluble in the refrigerating machine oil.
