The aim of this work is to experimentally investigate the performance of a domestic refrigerator to minimise power with proper control of temperature. A small fan is placed behind the defreezer, so as to convert natural flow of cold air to forced flow of cold air which eventually would result into more efficient cooling. Different lengths of condenser were tested in order to obtain reduction in power consumption. Among different lengths of condenser better length of condenser is selected and calculations are performed.Data are collected in order to evaluate the refrigerator performance. Each data was collected for a cycle of operation for 1 hour, 2 hour, 3 hour and 24 hrs.Result and analysis of Normal Refrigerator were compared with new modified refrigerator on basis of power consumption and COP. Power consumption decreased from 218 watt/hr to 36 watt/hr with modified refrigerator.

Keywords : Refrigerator, R134a, Micro-Controller, Condenser, Refrigerator fan motor,Power Consumption, COP.
