摘要：

The invention provides a heat transfer composition consisting essentially of from about 82 to about 88 % by weight of -1,3,3,3-tetrafluoropropene (R-1234ze(E)) and from about 12 to about 18 % by weight of 1,1-difluoroethane (R-152a). The invention also provides a heat transfer composition comprising from about 5 to about 85 % by weight R- 1234ze(E), from about 2 to about 20 % by weight R-152a, and from about 5 to about 60 by weight 1,1,1,2-tetrafluoroethane (R-134a).
