Beschreibung
Zusammenfassung:	The present invention provides a refrigerant-containing composition by using a refrigerant that has a refrigerating capacity equivalent to that of widely used R404A, and a low GWP. Specifically, the present invention provides a composition that contains a refrigerant containing difluoromethane (R32), pentafluoroethane (R125), 1,1,1-trifluoroethane (R143a), 2,3,3,3-tetrafluropropene (R1234yf), and 1,1,1,2-tetrafluoroethane (R134a) in specific concentrations.
