    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.

    摘要: An absorptive refrigeration method and refrigerant/absorbant pairs comprising fluorinated organic compounds, such as fluorinated organic compounds having from one to eight carbon atoms (C1-C8), including hydrofluoroolefin and/or hydrochlorofluoroolefin compounds. In certain embodiments, a fluorinated organic compound, including certain hydrofluoroolefin and/or hydrochlorofluoroolefin compounds (e.g. C2-C4 hydrofluoroolefin and/or hydrochlorofluoroolefin compounds) is/are utilized as the refrigerant, with the absorbant portion either being a fluorinated organic compound or a non-fluorinated oil.
