“…The TOPSIS method is one of the best methods for selecting the optimum value from a number of optimum solutions. The optimum point is chosen by selecting the point farthest to the non-ideal point and the point that is closest to the ideal point (Nasruddin et al, 2017). Table 5 gives information about the optimum point selected by using the TOPSIS method.…”

Scientists have worked assiduously to find low GWP refrigerants for HVAC systems that specifically address the environmental problems of ozone depletion and global warming. R1234ze and R1234yf were considered as potential alternatives to conventional refrigerants such as R410A. Thermodynamic analysis of 4 kW air conditioning systems was conducted to assess system performance of R1234ze and R1234yf. Furthermore, exergy and exergo-environmental analysis were carried out for the heat pump system using selected environmentally friendly refrigerants. Finally, by using a multi-objective genetic algorithm, the optimum operating condition, including evaporation temperature, condensing temperature and mass flow refrigerant was determined. The result showed that the optimum operating condition of 20 o C evaporation temperature, 42.57 o C condensation temperature and 0.02 kg/s mass flow rate, led to exergy efficiency of 51.92% and an exergo-environmental value of 101.925 mPts/h. R1234ze has a comparable performance to R410A or performs even better.

“…One of the problems in heating, ventilation, and air conditioning (HVAC) systems is finding an alternative refrigerant that can provide high system performance but have low environmental effects (Nasruddin et al, 2017). The world's attention to environmental damage is known to continually increase; hence, efforts in finding alternative refrigerants continue to be conducted.…”

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%.

“…The used of low global warming potential (GWP) refrigerant could be an option to minimize the effect of the system on the environment (Nasruddin et al, 2017;Aisyah et al, 2018;. Mastrullo et al (2016) conducted a simple model for the thermal cabin system to compare the energy consumption and total equivalent warming impact (TEWI) value of R134a to the new environmentally friendly refrigerants R1234yf and R1234ze.…”

This paper investigates the use of two low global warming potential working fluids, HCFO-1224yd(Z) and HCFO-1233zd(E), in high-temperature heat pump systems. A simulation was performed at evaporating temperatures ranging from 50-70°C and a condensing temperature of 110°C. A solar thermal collector was used to supply the energy needs on the evaporator side. Energy, exergy, and environmental analyses were performed to evaluate both environmentally friendly refrigerants and compare them to HFC-245fa. The coefficient of performance (COP) and total exergy destruction represented the performance of the system, while the total equivalent warming impact was used to evaluate the environmental effect of each refrigerant. At an evaporation temperature of 50°C, HCFO-1224yd(Z) and HCFO-1233zd(E) showed comparable performance to R245fa, with COP values of about 2.74 and 2.69, respectively (R245fa had a COP value of about 2.66). The same results were also obtained at evaporation temperatures of 60°C and 70°C, at which R1224yd showed good performance compared to R1233zd and R245fa with COP values of 3.6 for 50 o C evaporation temperature and 4.75 for 70 o C evaporation temperature. Additionally, both suggested refrigerants had low direct emission compared to R245fa based on the results from the environmental analysis.
