    摘要: A novel ternary mixture of refrigerants that can be drop-in substituted for dichlorodifluoromethane (R-12), but that, unlike dichlorodifluoromethane, causes very little ozone damage, comprising aproximately 2 to 20% by weight isobutane (R-600a), approximately 41 to 71% by weight chlorodifluoromethane (R-22), and aproximately 21 to 51% by weight chlorodifluoroethane (R-142b), with the weight percentages being of the overall mixture.

    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-170, R-1270, R-1216, R-218, R-C318, R-C270), that may be combined in novel ways to produce several excellent nulldrop-innull substitutes for refrigerants R-12 or R-500. The performance of the preferred nulldrop-innull 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.
