EXPERIMENTAL STUDY OF DOMESTIC REFRIGERATOR BY VARYING THE FINS SPACING OF THE CONDENSER

Abstract

An Experimental Analysis is done of the refrigerator condenser by varying the fins spacing of the condenser. Vapour compression refrigeration system is a cycle in which domestic refrigerator works. it consist of compressor, condenser expansion valve and evaporator . The performance of the system depends on the performance of all the components of the system. The main objective of the present work is to increase the performance of the condenser by increasing the heat transfer rate through the condenser. Heat transfer rate can be increased by the extended surfaces called fins. Heat transfer rate is also depends on the spacing between the fins of the condenser. In the present experimental work several condensers having different fins spacing are taken. By using this parameter experiments are conducted on a domestic refrigerator of capacity 165liters. The effect of varying the condenser fins spacing on the performance of refrigerator condenser is calculated experimentally. to do so 4mm, 6mm & 9mm condenser spacing are taken and behaviour of refrigerator was checked with help of parameters like pull down time, COP, compressor discharge pressure, energy consumption.
