Abstract
Compositions containing 2,3,3,3-tetrafluoropropene and to the uses thereof as heat transfer fluid, expansion agents, solvents and aerosol. Compositions essentially containing between 10 and 90 wt. % of 2,3,3,3-tetrafluoropropene, between 5 and 80 wt. % of HFC-134a and between 5 and 10 wt. % of HFC-32. Compositions essentially containing from 10 to 45% by weight of 2,3,3,3-tetrafluoropropene, from 50 to 80% by weight of HFC-134a and from 5 to 10% by weight of HFC-32.
