摘要
Compositions, methods and systems for the transfer of heat, including (a) HFC - 32; (b) HFO - 1234ze; and (c) or 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 HFP - 1234ze / and (c) of more than about 0% to about 30% by weight of HFCS.- 152A.The amount of each of the components (a), (b) and (c) can be selected to ensure that the speed of the burning of the composition is less than about 10.The global warming potential of the composition is less than about 500.Where the composition has a cop of within 5% of R22 in the air conditioning system operated in an ambient temperature of at least 35 u00b0 C.
