    Abstract: A group of refrigerant fluids that may be combined in novel ways to produce several excellent "drop-in" substitutes for R-134a refrigerant. Performance is increased by constructing a zeotropic mixture of refrigrants, such that a single boiling point (of R-134a) is replaced by a "temperature glide" between the mixture's "bubble point" and "dew point". The temperature glide causes the phase change area in the condenser to be larger than with a single component refrigerant such as R-134a, thereby increasing heat rejection of the condenser, which lowers head pressures, and increases capacities and efficiencies compared to R-134a. Components are also selected to attempt to reduce the overall critical temperature of the mixture of refrigerants, also increasing performance and lowering head pressures under hot conditions with undersized condensers. Finally, a small amount of a mineral oil miscibility improver may be added, not to return mineral oil from the evaporator as in R-12 systems, but to keep waxes, tars, and other contaminates in the system that may have arisen from the manufacturing process (such as wax coatings on the motor windings in a hermetic compressor, or "tar" from valve packing) soluble.

    Abstract translation: 一组制冷剂流体可以以新颖的方式组合,以产生几种优异的“滴入”替代R-134a制冷剂。 通过构建反渗透剂的非共沸混合物来提高性能,使得单一沸点(R-134a)被混合物的“起泡点”和“露点”之间的“温度滑移”代替。 温度滑行导致冷凝器中的相变面积大于单一组分制冷剂如R-134a,从而增加冷凝器的排热,降低了头部压力,并提高了与R-134a相比的容量和效率。 还选择组分来试图降低制冷剂混合物的总体临界温度,同时在较小的冷凝器的热条件下也提高了性能并降低了头部压力。 最后,可以添加少量的矿物油混溶性改进剂,而不像R-12系统那样从蒸发器返回矿物油,而是将蜡,焦油和其他污染物保留在制造中可能产生的蜡,焦油和其他污染物 过程(如密封式压缩机中电机绕组上的蜡涂层,或阀芯填料的“焦油”)可溶。
