Abstract
An object is to provide a novel low-GWP mixed refrigerant. Solution means is a composition comprising a refrigerant, wherein the refrigerant comprises trans-1,2-difluoroethylene (HFO-1132(E)) and difluoromethane (R32) in a total amount of 99.5 mass % or more based on the entire refrigerant, and comprises HFO-1132(E) in an amount of 63.0 mass % to 68.3 mass % based on the total amount of HFO-1132(E) and R32; comprises HFO-1132(E) in an amount of 70.5 mass % to 76.5 mass % based on the total amount of HFO-1132(E) and R32; or comprises HFO-1132(E) in an amount of 81.6 mass % to 83.7 mass % based on the total amount of HFO-1132(E) and R32.
Claims10
