Abstract

This study thermodynamically analyze the minimum temperature difference (D_T) of a cascade condenser of cascade refrigeration system using R134a- R23 in order to get maximum COP of the system, by considering different operating parameters. The operating parameters includes: (1) the condensing (T_C) and evaporating temperature (T_me) of R134a, (2) the condensing (T_mc) and evaporating temperature (T_E) of R23. This analysis was also done experimentally on a cascade refrigeration system using R134a-R23 as refrigerant pairs. The experimental results are validated with the theoretical results and the results were in good agreement with each other.
