Comparative Evaluation of Energy and Exergy Performances of R22 and its Alternative R407C, R410A and R448A Refrigerants in Vapor Compression Refrigeration Systems

Öz

One of the important parameters for cooling systems is the choice of refrigerant. Refrigerants used in cooling systems damage the atmosphere and cause global warming. For these reasons, alternative refrigerants which are not harmful to the environment and atmosphere have been used. In this study, the performance and exergy efficiency of R407C, R410A and R448A refrigerants which are alternative to R22 refrigerant in vapor compression refrigeration system were theoretically calculated. Engineering equation solver (EES) has been used for the thermodynamic analysis. The highest COP and exergy efficiency values were achieved in the system operating with refrigerant R22. The highest COP and exergy efficiency values after R22 fluid were determined in the system operating with R448A refrigerant. For different evaporator temperatures, the COP values of the R22 system vary between 2.7 and 2.81. The COP values of the R448A system vary between 2.5 and 2.63. The exergy efficiency of the system operating with R22 varies between %39.4 and %52.2. The exergy efficiency of the system operating with R448A varies between %36.6 and %48.8. R448A instead of R22 are found to be replacement refrigerants among other alternatives refrigerants as a result of the analysis.
