To provide a refrigeration cycle apparatus capable of improving lubricity in the refrigeration cycle apparatus when the refrigeration cycle is performed using a refrigerant with a sufficiently small GWP. Provided is a refrigeration cycle device comprising a refrigerant composition and a refrigerating machine oil, the refrigerant composition comprising: trans-1,2-difluoroethylene (HFO-1132(E)), trifluoroethylene (HFO ‑1123) and 2,3,3,3‑tetrafluoro‑1‑propene (R1234yf). |
