|There has been plenty of research work carried out related to Comparison of Thermodynamic Analysis of Cascade Refrigeration System. However, very few
studies are done on different refrigerant pairs to improve the performance of Cascade Refrigeration System. The following research is based on systematic
literature review of A.D.Parekh,P.R. Tailor, Thermodynamic Analysis of Cascade Refrigeration System Using R12-R13, R290-R23 and R404A-R23, International Journal of Mechanical Engineering. The published authors have researched Thermodynamic analysis shows that out of three refrigerant pairsR12- R13, R290-R23 and R404A-R23 the COP of R290- R23refrigerant pair is highest. The authors have reviewed various journal papers and suggested to blend various pairs of refrigerant to obtain maximum COP of Cascade Refrigeration System. The review covers working principle, performance of desert cooler with respect to various position. The study focusing on to choose various pairs which has no ozone depletion potential (ODP=0) and no direct global warming potential (GWP=0) & all improve the performance of Cascade Refrigeration System. In addition, certain refrigerants pair are identified that would help researchers in future.
