Comparative Energetic, Exergetic, Environmental and Enviroeconomic Analysis of Vapour Compression Refrigeration Systems Using R515B as Substitute for R134a

Abstract

In this study, hydrofluoroolefin R515B was used rather than hydrofluorocarbon R134a to perform energetic, exergetic, environmental and enviroeconomic analyses on vapor-compression refrigeration systems with internal heat exchangers. The exergy efficiency, exergy destruction, and coefficient of performance for cooling mode (COP) were studied. EES (Engineering Equation Solver) program was employed for thermodynamic analysis. The impact on the COP, exergy destruction, and exergy efficiency of the system was investigated at various evaporator and condenser temperatures. Performance analysis shows that the COP of R515B refrigerant is like that of R134a. It has been found that the exergetic efficiency of R515B was slightly lower (about 1.40%) than that of R134a. It has also been found that at higher evaporation temperatures, the total exergy destruction increases. The most important exergy destruction occurs in the compressor. The environmental and enviroeconomic indexes of R515B refrigerant were like those of R134a. The results demonstrated that R515B may be a good alternative to R134a in the vapour-compression refrigeration systems with internal heat exchangers.
