Abstract

A simulation approach to heat pump systems is proposed in this paper. The evaluation of working fluids is conducted. Some alternative refrigerants, including R245fa, R32, R1234ze, and R1224yd are investigated. Moreover, the selected refrigerants are used in the simulation. The simulation is conducted using MATLAB software. Subsequently, the system is analyzed in terms of the coefficient of performance (COP) and exergy efficiency. The results indicate that R1224yd is the best refrigerant with regards to safety, environmental impact, and physical properties. Based on the energy and exergy analysis, R1224yd can attain a COP of 6.5 and exergy efficiency of 29.8%.
