Experimental investigation on the performance of air conditioner using R32 Refrigerant

This paper exhibits two approaches of refrigerant comparison for the retrofitting process in 1.5 ton capacity room air conditioning system. One is experimentation that was conducted for selected refrigerants using air conditioner test rig and calculate cycle performance analysis, another one is the simulation process by utilizing software like ASPENONE (aspen V8). With this software we can simulate the cyclic process of VCR system to work out the thermo physical properties of three refrigerants R22, R134a, and R32.The performance parameters includes the real coefficient of performance, mass flow rate, and power passed to the compressor. Under the class A2L ASHARE standers R32 has been accepted as safety group refrigerant because the atmospheric life for R22 is 15 years and for R32 is 4.9 years. By taking these performance results and simulation results the R32 is the efficient refrigerant for the retrofitting of an air conditioning system.
