Abstract
This study presents a comparative analysis of thermodynamics performance of cascade refrigeration systems(CRSs) for refrigerants pairs R23/R404a and R41/R404a to discover whether R41is suitable substitute for R23.The discharge temperature,coefficient of performance(COP),exergy loss(x),and exergy efficiency are chosen as objective functions.The operating parameters considered in this paper include condensing temperature,evaporating temperature in both high-temperature cycle(HTC)and low temperature cycle(LTC).The results indicate that overall R41/R404a has a better performance than R23/R404a in cascade refrigeration system.
