## Abstract

Compositions are disclosed comprising: (a) 1,1,1,2,2-pentafluoropropane; (b) a compound selected from the group consisting of 2,3,3,3-tetrafluoropropene, E-1,3,3,3-tetrafluoropropene, and 1,1,1-trifluoropropene; and optionally (c) a compound selected from the group consisting of 1,1,1,2-tetrafluoroethane and difluoromethane. Such compositions are useful in methods to produce cooling, produce heat, transfer heat, form a foam, produce aerosol products, for recovering heat, and for replacing existing refrigerants. Additionally, these compositions are useful in refrigeration, air conditioning and heat pump apparatus.
