ENERGY PERFORMANCE OF HYDROCARBON REFRIGERANT AS A POSSIBLE ALTERNATIVE REFRIGERANT TO R134A IN DOMESTIC REFRIGERATORS [PDF]
Journal of Al-Azhar University Engineering Sector, 2019 The performance of a domestic refrigerator is theoretically assessed in this study. Therefrigerator utilizes R1234yf as an alternative refrigerant for R134a. The performance isevaluated for three condensing temperatures, specifically, 30, 40, and 50°C at differentevaporator temperatures, ranging −30 and 0°C.
