A Performance of a Window Air Conditioner Using Alternative Refrigerants R22 AND R410A

This paper presents the experimental performance analysis of a window air conditioner using two refrigerants R22 and R410A.The effect of the different parameters of performance analysis (refrigeration capacity, COP, compressor power ,pressure ratio ) were investigated for various evaporating temperature and ambient temperature. .The result shows that refrigerant R22 is better than R410A in case of COP, refrigeration capacity but for pressure ratio and compressor power R410A shows better performance than R22.Since R22 refrigerant has better performance than also this refrigerant is replaced by the end of 2015.Due to their severe environmental impact.
