COMPOSITION CONTAINING REFRIGERANT INCLUDING R32, R125, R143a, AND R134a AND REFRIGERATION METHOD USING SAID COMPOSITION, METHOD FOR OPERATING REFRIGERATOR, AND REFRIGERATOR

摘要

Provided is a refrigerant-containing composition that uses a refrigerant having a refrigeration capacity equivalent to that of the currently used R404A and a small GWP. Provided is a refrigerant-containing composition, wherein the composition is characterized in that the refrigerant includes difluoromethane (R32), pentafluoroethane (R125), 1,1,1-trifluoroethane (R143a), and 1,1,1,2-tetrafluoroethane (R134a) in specific concentrations.
