Low temperature Cascade Refrigeration Systems (CRS) are used when the temperature that has to be maintained by the refrigeration system is very low. When a single stage vapour compression system or a vapour absorption system are unable to achieve very low temperatures, a low temperature CRS is utilized. Successful design of CRS mainly depends upon the selection of refrigerants for both temperature circuits: high temperature circuit &low temperature circuit. The main objective of my research work is to compare different CRS using refrigerant pairs R12-R13, R290-R23, & R404A-R23. Thermal performance analysis is carried out by developing computational model in Engineering Equation solver (EES). The impact of different operational factors, such as evaporator and condenser temperatures on performance measures such as COP, exergetic efficiency, as well as refrigerant mass flow ratio has been investigated. Thermodynamic research reveals that the R290-R23 refrigerant pair has the greatest COP among the three refrigerant pairings R12-R13, R290-R23, & R404A-R23.
