摘要

To replace chlorofluorocarbons as refrigerant fluids, the invention proposes to employ mixtures containing, on a mass basis, approximately 25 to 65 % of 1,1,1-trifluoroethane, 1 to 70% of perfluoropropane, and 5 to 34 % of propane. The mixtures according to the invention can also be employed as aerosol propellants or as blowing agents for plastic foams.
