Analysis of heat pumps with zeotropic refrigerant mixtures by taguchi method

The goal of this work is to determine the optimum set of parameters by using the taguchi method in vapour compression heat pump systems. the experimental apparatus consist of an air-to-liquid vapor compression heat pump,a water cooled condenser,a forced air evaporator,an electrical air and water heaters,and various measuring elements and other auxiliary equipments. refrigerants r22,r407c,and five of their binary mixtures which contain about 0%,25%,50%,75%,and 100% mass fractions of r407c were tested. to determine the effect of the chosen parameters on the system and optimum working conditions,an experimental design method suggested by genichi taguchi was used. the most effective parameters are found to be the condenser water mass flow rate for the coefficient of performance and to be condenser water inlet temperature for the exergetic efficiency. ©2008 tibtd printed in turkey.
