摘要： Hydrofluorocarbon compositions which consist of more than 50 to less than 60% wt of HFO-1234yf, and of more than (40) to less than 50 wt % HFC-134a are useful as drop-in substitutes for R-404A, R-507 and R-22. The invention also concerns azeotropic hydrofluorocarbon compositions consisting equal to or more than 56.3 to equal to or less than 58.0 wt of HFO-1234yf, and equal to or more than 42.0 to equal to or less than 43.7% wt of HFC-134a.
