Abstract – Most of the household refrigerators work on the Vapor compression refrigeration system which has high coefficient of performance. The system consists of components like compressor, condenser, expansion valve and evaporator. The system performance depends on the performance of all the components of the system. The main objective of the paper is to find coefficient of performance of refrigeration system using conventional condenser (MS with Cu coating) and then verifying effect of performance using conventional condenser made of copper material on Kelvinator refrigerator of refrigeration capacity 165 lts, hermitic sealed compressor unit with R134a as refrigerant. Further an attempt is made in modifying the conventional shaped condenser to spiral shaped condenser and with varying pitch the performance of system is evaluated. Finally it is noticed that spiral shaped condenser has given the maximum COP among all observations.
