    摘要: A refrigerant composition. The composition has 25 to 35 mass % difluoromethane, 20 to 40 mass % pentafluoroethane, and 35 to 45 mass % tetrafluoroethane. The composition exhibits a positive superheat at an evaporation temperature of about −30° F. There is also a process for producing refrigeration and a refrigeration system.
