Zusammenfassung:Disclosed are compositions containing pentafluoroethane, 1,1,1,2-tetrafluoroethane and at least two hydrocarbons each having eight or fewer carbon atoms. Disclosed herein are compositions containing about 13 weight percent to about 20 weight percent pentafluoroethane; about 70 weight percent to about 80 weight percent 1,1,1,2-tetrafluoroethane; about 1 weight percent to about 6 weight total of at combination of hydrocarbons consisting of n-butane and n-pentane. Also disclosed herein are compositions further comprising 1,1,1,2,3,3,3-heptafluoropropane. Also disclosed are azeotrope-like compositions comprising pentafluoroethane, 1,1,1,2-tetrafluoroethane, n-butane and n-pentane and azeotrope like compositions comprising pentafluoroethane, 1,1,1,2-tetrafluoroethane, n-butane, n-pentane, and 1,1,1,2,3,3,3-heptafluoropropane.
