The present invention addresses a problem of providing a mixed refrigerant that combines three kinds of performances of having a refrigeration capacity (this may also be referred to as a cooling capacity) and of having a coefficient of performance (COP) equivalent to those of R410A, and of having a sufficiently small GWP. As a means for solving the problem, provided is a refrigerant-containing composition, wherein the refrigerant contains trans-1,2-difluoroethylene (HFO-1132 (E)), trifluoroethylene (HFO-1123) and 2,3,3,3-tetrafluoro-1-propene (R1234yf), and R32. |
