The present work deals with thermodynamic analysis of a R-134a/R-23 cascade refrigeration system to evaluate the maximum COP and the minimum temperature difference (DT) corresponding to , by considering different operating parameters. The operating parameters includes: the condensing () and evaporating temperature () of R-134a and the condensing () and evaporating temperature () of R-23. A computational model has been developed for the considered system to evaluate the and DT corresponding to based on the thermodynamic principles. A mutilinear regression analysis has been carried out to evaluate two correlations for calculating and minimum DT considering the above operating parameters. The exergy analysis of the system is also performed to determine the irreversibility losses of the system as well as for the components. It has been found that the total exergy destruction rate of the system is lower at minimum .
