Experimental Investigation of Performance of R134a/R152a Refrigerant Mixture in Heat Pump
Abstract :
In this study, the performance of mixture R134a and R152a at different mass ratio was experimentally investigated in heat pumps. Vapour temperature, condenser pressure and ratio of mixture were considered as experiment parameters. Thermodynamic values of refrigerant mixtures based on the temperature and pressure values measured in experimental unit were obtained from REFPROP 7.0 software. The performance values were calculated using equations that are derived from the first law of thermodynamics. The results obtained in this study indicated that the coefficients of performance (COP) were improving from %5 to %23 in heating and, from %6 to %28 in cooling by the increasing rate of R152a refrigerant fluid in mixture.
