Design and Experimental Analysis of Waste Heat of Condenser in VCR System

Increasing demand of energy and global warming is the current issue before us. Substantial increase of energy demand compelled us to think on waste heat utilization perspective. To mitigate the energy crisis and to save our environment recovery of waste heat is utmost necessary. Our main objective to present this paper is to show the percentage of waste heat utilization possible from condenser of a household refrigerator. The condenser of refrigerator acts as a heat pump and discharge heat inside room hence increases the room temperature. This discarded waste heat can be reutilized for number of domestic purposes such as heating water, maintaining food hot, cloths and grain drying. Experimentally we have shown that with waste heat recovery the overall COP of the system increases. By installing the waste heat recovery unit with domestic refrigerator it has become a multipurpose refrigerator fulfills both cooling and heating requirements.
