    Abstract: Heat transfer compositions, methods, and systems including (a) HFC-32; (b) HFO-1234ze; and (c) either HFC-152a. In certain aspects, such compositions include (a) from about 33% to about 70% by weight of HFC-32; (b) from about 20% to about 66% by weight of HFO-1234ze; and (c) from greater than about 0% to about 30% by weight of HFC-152a. The amount of each of the components (a), (b) and (c) may be selected to ensure that the burning velocity of the composition is less than about 10, the global warming potential of the composition is less than about 500, wherein said composition exhibits a COP of within 5% of R22 in an air conditioning system operated at an ambient temperature of at least 35° C.

    Abstract translation: 传热组合物,方法和系统,包括(a)HFC-32; (b)HFO-1234ze; 和(c)HFC-152a。 在某些方面,这些组合物包括(a)按重量计约33%至约70%的HFC-32; (b)约20重量%至约66重量%的HFO-1234ze; 和(c)大于约0%至约30%重量的HFC-152a。 可以选择每种组分(a),(b)和(c)的量以确保组合物的燃烧速度小于约10,组合物的全球变暖潜能值小于约500,其中 所述组合物在至少35℃的环境温度下操作的空调系统中显示出R22的5%以内的COP。
