The choice of refrigerants for the High Temperature Circuit and the Low Temperature Circuit is the most important part of the design of a Cascade Refrigeration System (CRS). My research project's goal is to look at two different Cascade Refrigeration Systems that use two different sets of refrigerant, R41/R290 and R41/R404A. Thermodynamic analysis is done on the performance of Cascade Refrigeration System with R41/R290 refrigerant pair and R41/R404A refrigerant pair. This is done with the help of a mathematical model. Mathematical modeling is done with the help of the EES-Engineering Equation Solver software. Under different operating conditions like TEVA, TCON, and TCASLTC, the performance of a Cascade Refrigeration System was looked at in terms of Coefficient of Performance, total exergy destruction, total work and exergetic efficiency. The results indicate that the Coefficient of Performance of the refrigerant pair R41/R290 used in a Cascade Refrigeration System is higher than the Coefficient of Performance of the refrigerant pair R41/R404A used in the same operating conditions.
