Abstract
The present work reports the experimental performance evaluation of aluminum suction line-based domestic refrigerators. Furthermore, it compared domestic refrigerators with conventional copper capillary tubes and suction lines using R600a as a refrigerant. Performance parameters: energy consumption, ice-making time, and pull-down time was reduced significantly compared to conventional copper suction and capillary tube. Refrigerants having Ambient temperature for ice making test and pull down were initially set at 43°C and that for rated energy consumption test was at 32°C. For ice making test, the test thermostat was set in such a manner that stable operating conditions were obtained in the coldest position before starting the test. For the rated power consumption test, the refrigerator has to run on no load condition and the temperature of the evaporator does not exceed 5 ± 0.5°C at the geometric center. Power consumption was reduced by 7.24%, Ice making time was reduced by 6.27%, and Pull downtime was reduced by 6.39% using an aluminum-based suction line and capillary tube. 68.49% reduction in the cost of aluminum-based capillary tubes and suction lines was observed. All the performance tests were done in a testing chamber at particular conditions. This research work will be helpful to the researchers in developing a new low-cost model of the domestic refrigerator without degrading the quality.
