| Abstract | ||||
| The performance of a domestic refrigerator is theoretically assessed in this study. The refrigerator utilizes R1234yf as an alternative refrigerant for R134a. The performance is evaluated for three condensing temperatures, specifically, 30, 40, and 50°C at different evaporator temperatures, ranging −30 and 0°C. The performance of the refrigerator is compared in terms of volumetric cooling capacity, coefficient of performance, compressor power consumption and discharge temperature. The results of the study confirm that R1234yf is an efficient and environment-friendly substitute for R134a that can be used in domestic refrigerators. | ||||
