| Popis: | The volumetric and thermodynamic properties of fluorinated ethers such as trifluoromethyl-1-H-pentafluoroethylether, F-oxetane, 2-H-heptafluoropropane, pentafluorodimethylether, F-methyl methyl ether, perfluorodoxolane, pentafluorodimethoxymethane and HFCs such as trifluoroethane, heptafluoropropane, difluoroethane, pentafluoropropane, ethyl fluoride as alternatives to replace R134a have been predicted using SRK equation of state over the temperature range from − 25 °C to + 55 °C. Theoretical analysis is carried out using ten-point vapour compression cycle for screening of candidate refrigerants. The results of analysis have been used to ascertain standard refrigeration parameters in respect of each of the candidate refrigerants. The analysis indicates that the performances of difluoroethane, ethyl fluoride, pentafluorodimethylether and F-oxetane are better than that of R134a. |
