Global warming and energy demand is the present scenario before us. Increasing demand of energy compelled us to take necessary steps to recover waste heat from several sources. To fulfil the energy crisis and global environment protection utilization of waste heat should be the prime focus. The main aim of this paper is to find the best possible way to recover the waste heat from condenser of a domestic refrigerator. We know that the condenser of refrigerators reject large heat inside room which make us uncomfortable in summer due to temperature rise. This waste heat can be utilized for number of household purposes such as keeping food hot, heating water, cloths and grain drying. This seems to be a most valuable optional approach to improve overall efficiency of refrigerator and utilize the waste heat. This research shows that such a system is possibly feasible and economically suitable.
