The present disclosure addresses the problem of providing a refrigerant composition that has a low GWP and a refrigerating capacity equivalent to that of R4 04A, which is currently widely used. As a solution to the problem, the present disclosure provides a composition containing carbon dioxide and a mixture of fluorinated hydrocarbons, the mixture containing difluoromethane (R32), pentafluoroethane (R1 25) , 2,3,3,3-tetrafluoropropene (R1 234yf), 1,1,1,2-tetrafluoroethane (R1 34a), and carbon dioxide (CO<sub>2</sub>) in specific concentrations. |
