ANALYSIS OF MIXTURES OF REFRIGERANT FOR VAPOUR COMPRESSION REFRIGERATION CYCLE USING MATLAB-SIMLINK

The goal of this work is to predict the performance of the compression cycle of different refrigerants. Incompression refrigeration system, the refrigerant such as R22, R290 & R407C are considered as a refrigerant bymixing of these at a different mass fraction as 40%+30%+30%, 30%+40%+30%, 30%+30%+40%, 40%+20%+40%,40%+40%+20% and 20%+40%+40% respectively. Experimental conditions for the condensing temperature wereselected as 40,45&50 °C and evaporating temperature were selected 1,5 & 10°C. Various performance measures likeCOP, Volumetric Efficiency, Mass Flow Rate, Isentropic Compressor Work, Refrigeration Capacity, Compressorpower, Compressor Outlet Temperature, Pressure Ratio & Overall Performance Index uses a several refrigerantmixture with the help of MATLAB-SIMLINK tool. Among these pure refrigerants and mixture of refrigerantsgroup, R290 and 40%+40%+20% has a better COP
