Improving the Performance of Household Refrigerator by Recovering Heat from the Condenser

Y.A.Patil | H.M.Dange

Abstract: Refrigerator has become an essential commodity rather than luxury item. The heat absorbed in refrigerated space and the compressor work added to refrigerant is too rejected to ambient through a condenser. Our aim is to recover waste heat from condenser unit of a household refrigerator to improve the performance of the system. The heat recovery from the household refrigerator is by thermo siphon. From the experimentation it was found that after recovering heat from the condenser of the conventional refrigerator its performance get improved than conventional refrigerator. The maximum temperature achieved in water tank with 100 liter of water is 45C at the full load condition. If the water tank contains 50 liter water then it gets heated to 45 C in just 5 to 6 hrs. After that performance of the system gets decreased. So it needs regular use of that hot water
