    摘要: A group of known refrigerants, (R-227ea, R-124, R-134a, R-143a, R-125, R-E125, R-E143a, R-E227ca2, R-254cb, R-600a, R-142b, R-22, R-290, R-E170, R-1270, R-1216, R-218, R-C318, R-C270), that may be combined in novel ways to produce several excellent “drop-in” substitutes for refrigerants R-12 or R-500. The performance of the preferred “drop-in” substitutes for R-12 or R-500 of the present invention often exceeds that of the refrigerant being replaced, while maintaining acceptable oil circulation with existing mineral oils used in R-12 or R-500 refrigeration and air conditioning systems.

    摘要: A refrigerant composition for use in a vapour-compression refrigeration apparatus as a replacement for currently used refrigerants R22 and R12 comprises a mixture of pentafluoroethane (R125), tetrafluoroethane (R134a), a hydrocarbon selected from isobutane (R600a) and propane (R290), and optionally octafluoroethane (R218). The composition contains no chlorine atoms and is non-depleting to atmospheric ozone; but specific compositions have pressure-temperature relations substantially the same as R22 and R12 thereby allowing their use as direct replacements therefor in existing refrigeration apparatus.

    摘要: The present invention relates to a refrigerant mixture for substituting R502, R22 or R12 used in a vapor compression refrigerator or air conditioner and a refrigeration system using the same. More specifically, the present invention relates to a refrigerant mixture comprising a combination of two or three components, which is capable of being used without causing ozone layer destruction and global warming and at the same time, without replacement of the existing refrigeration system, wherein the components are selected from the group consisting of propylene, propane, 1,1,1,2-tetrafluoroethane, pentafluoroe thane, 1,1,1-trifluoroethane, 1,1-difluoroethane, dimethylether and isobutane; and a refrigeration system using the same.
