Experimental study of a new hydrocarbon mixture for domestic re-frigerator to replace R134A
Abstract
In a domestic refrigerator with 4.49cc displacement compressors, the performance of R290 (48 by mass percent) and R600a (52 by mass percent) was examined experimentally. In our research, we employed a 210-litre refrigerator designed to run on R12 with a longer capillary. The amount of energy utilized and the pressure and temperature at crucial locations on the various refrigerated compartments and refrigerator circuits are all monitored. With R290/R600a, we performed a scroll-down test and ice-making test. According to our findings, R290/R600a are the best contenders for replacing R134a in terms of energy conservation. Because the amount of refrigerant utilized is so small, the flammability factor can be overlooked.
