Claim Text:
1. A high temperature heat pump system comprising a compressor, an evaporator, and a condenser operating at a condenser temperature of greater than 100° C., wherein a heat transfer composition flows through the system, the heat transfer composition comprising a refrigerant having a global warming potential (GWP) of not greater than about 150 and comprising: from about 60% to about 85% by weight of HFO-1233zd, wherein said HFO-1233zd consists essentially of HFO-1233zd(E); and from about 10% to about 40% by weight of HFO-1234ze, wherein said HFO-1234ze consists essentially of HFO-1234ze(E); provided the refrigerant has: (1) a capacity of at least about 90% relative to CFC-114 in said high temperature heat pump system; (2) a COP of at least about 95% relative to CFC-114 in said high temperature heat pump system; and (3) a glide of less than about 3° C. in said high temperature heat pump system.
