Abstract

This study proposes the parameter study and multi-objective optimization of a vapor compression heat pump system using environmentally friendly refrigerant, R1224yd(Z). The effect of three design parameters including refrigerant mass flow rate, evaporation temperature, and condensation temperature on compressor work, cooling load in the evaporator, heat rejected by the condenser, and exergy of the system are investigated through parameter studies. A multi-objective optimization was then performed. Exergy efficiency and exergoenvironmental value are the objectives of this optimization scenario. The purpose of the optimization is to obtain the optimum value of three design parameters in terms of exergy and environmental point of views so that the heat pump system has maximum exergy efficiency and minimum effect to the environment. The result showed that the system will be in the optimum condition at Te = 287.98 K, Tc= 315.56 K and refrigerant mass flow rate = 0.0321 kg/s with the exergy efficiency of 38.48% and exergoenvironmental value of 200.98 mPts/h.
