Title: The effect of selecting proper refrigeration cycle components on optimizing energy consumption of the household refrigerators
Abstract: This paper presents experimental results of hot-wall condenser removal, condenser air cooling increment, capillary tube diameter effect, compressor cooling capacity effect, changes of R134a charge amount and ambient temperature effect on a commercial bottom mounted freezer to decrease energy consumption and production cost. Experiments were carried out on a 418 L dual evaporator domestic bottom mounted freezer using 155 g R134a as the refrigerant. As a result, the improvement of refrigerator energy consumption was studied experimentally. Investigations made under controlled conditions have shown that the more the heat removed from the condenser, the higher the efficiency can be. Data were provided under the standard conditions for evaluating energy consumption and efficiency of refrigerators. Results showed that by hot-wall condenser removal, condenser air cooling increment and decreasing compressor cooling capacity, energy consumption and refrigerant charge amount reduced by 23.6% and 19.3%, respectively.
