Theorotical Exergy Analysis of Actual Vapour Compression System with HFO-1234yf and HFO-1234ze as an Alternative Replacement of HFC-134a
Shobhit Mishra [3] | M. Emran Khan [4]
Abstract: This paper deals with the comparison of hydrofluoroolefins (HFO-1234yf & HFO-1234ze) and HFC-134a in a vapor compression system equipped with liquid vapour heat exchanger (LVHE). HFO-1234ze (trans-1, 3, 3, 3-tetrafluoroprop-1-ene) and HFO-1234yf (2, 3, 3, 3-Tetrafluoropropene) have ultra low Global Warming Potential (GWP) and zero Ozone Depletion Potential (ODP). For exergy analysis a mathematical computational model has been developed in Engineering Equation Solver (EES) for calculating different parameters. Results obtained indicates that hydrofluoroolefins (HFO-1234ze and HFO-1234yf) can be a good drop in replacement of R-134a. During the analysis, condenser temperature is 313K and evaporator temperature is taken in the range from 233K to 278K.
