The goal of this research is to compare the performance of a vapour compression refrigeration system using R-600a to a similar system having R-134a as a refrigerant. Both refrigerants have no potential to deplete the ozone layer. However, because R-134a is an HCF, its global warming potential is rather strong, whereas R-600a's is nearly none. The two refrigerants' desirable properties are compared. R-600a is a better refrigerant for a vapour compression refrigeration system, according to this comparison. The average values of the required parameters are then presented once a number of trials have been completed. To compare the refrigerants, the coefficient of performance, refrigeration effect, Carnot COP, and second law efficiency were calculated. The findings show that R-600a is a superior refrigerant. The system's primary components' exergy destruction has also been calculated. It demonstrates that the compressor has depleted its maximal exergy. R-600a is a strong alternative to R-134a, which is currently utilized in household refrigerators, according to the analysis.
