The effect of different performance analysis paramaters (refrigeration capacity, COP, compressor power, pressure ratio) have been studied for various evaporation temperature and ambient temperature. The experimental results obtained show that the refrigerant R22 is better than R410A in case of COP, refrigeration capacity, but for pressure ratio and compressor power the R410A shows best performance than R22. This refrigerant was replaced at the end of 2015 due to their severe environmental impact.R22, R410a, Performance
