Refrigeration plays a significant role across various aspects of human life and consumes substantial amounts of electrical *** rapid advancement of green cooling technology presents numerous solar-powered refrigeration systems as viable alternatives to traditional refrigeration *** analysis is a key in identifying actual thermodynamic losses and improving the environmental and economic efficiency of refrigeration *** this study exergy analyze has been conducted for a solar-powered vapor compression refrigeration(SP-VCR)system in the region of Gharda颽(Southern Algeria)utilizing R1234ze(E)fluid as an eco-friendly substitute for R134a refrigerant.A mATLAB-based numerical model was developed to evaluate losses in different system components and the exergy efficiency of the SP-VCR ***,a parametric study was carriedout to analyze the impact of various operating conditions on the system’s exergy destruction and *** obtained results revealed that,for both refrigerants,the compressor exhibited the highest exergy destruction,followed by the condenser,expansion valve,and ***,the system using R1234ze(E)demonstrated lower irreversibility compared to that using R134a *** improvements made with R1234ze are 71.95%for the compressor,39.13%for the condenser,15.38%for the expansion valve,5%for the evaporator,and 54.76%for the overall system,which confirm the potential of R1234ze(E)as a promising alternative to R134a for cooling applications.
