Energy performance of hydrocarbon refrigerant as a possible alternative refrigerant to R134A in domestic refrigerators

Abstract EN

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.
