TECHNOECONOMIC ASSESSMENT OF ALUMINIUM SUCTION BASED DOMESTIC REFRIGERATOR

Abstract

The main objective of the present study is to enhance the performance of domestic refrigerator, working on vapor compression refrigeration cycle. Enhancement of domestic refrigerator performance with Copper suction and capillary has been reported by many of the researchers. This thesis shows the results of an experimental work based on the aluminium suction line. Conventionally copper was used for making capillary tube and suction line for the enhancement of overall performance, copper suction line is changed into aluminium suction line. Results show that some of the important factors which help in improving the overall performance of a domestic refrigerator involve energy consumption, ice making time and pull down time. These factors reduced to a significant margin as compared to conventional Copper suction and capillary tube. Low cost material of aluminium also helped in cost reduction without degrading the quality of product which also helps large manufacturing industries. Power consumption reduced by 7.24%, Ice making time reduced by 6.27%, Pull down time reduced by 6.39% by using aluminium based suction line and capillary tube. Total reduction observed in expenditure is 68.49% that helped project to save cost. This research work will be helpful for the researchers to develop a new low cost model of domestic refrigerator and will help in enhancing the overall performance.
