Abstract

Refrigerator has become an essential commodity rather than luxury item. The heat absorbed from space to be refrigerated (Evaporator) and the heat from the compressor is added to refrigerant is rejected to the surrounding through a condenser. This heat can be recovered and used for the various purposes. Paper represents research work on a design of compact condenser (shell and tube type) for effective heat recovery in minimum possible time and cop enhancement of the domestic refrigerator. The modified condenser can mounted in the vacant space just above the compressor. Therefore vacant space is utilized and handling problems due to bare copper tube is also reduced. Natural circulation of water eliminates use of pump. Cad modeling and matlab programming are performed for ease in manufacturing and to determine the dimensions of the proposed condenser. By the experimental investigation it is found that this modification in existing system increases the performance of system to 28.61%. It is observed that temperature of cold water rises to 500c just within 20 minutes. This hot water can be used for various purposes like dish washing, bath, laundry etc. Therefore the proposed system makes the household refrigerator to be work as both refrigerator and water heater.
