Abstract
This study focuses on energy performance investigation and environmental impact analysis of various single-refrigerants (R1234yf, R1234ze, R161 and R13I1) as possible alternatives to high global warming potential refrigerant R134a. To reach this objective, a numerical model is developed to evaluate and compare the cycle performance parameters of the single-refrigerants considered in this work with R134a, like cooling capacity, coefficient of performance, volumetric refrigerating capacity and the pressure ratio. The comparison was made at evaporating temperatures (Te) ranging from (-10 to 10 °C) and the constant condensation temperature (Tc) of 50 °C. The results proved that the application of R161 exhibited a higher of COP, cooling capacity, volumetric refrigerating capacity, as well as lower pressure ratio compared with R134a, which confirms that it could be a good suitable substitute for the R134a in terms of cycle performances and environmental protection.
