The principle of this project is to recovering waste heat from automobile vehicle and utilizes it for refrigeration affection. The waste heat from engine is recovered by using a copper tube wound around exhaust pipe of engine which contains water, which absorbs heat from flue gasses and supplies it to ammonia container through tubes. The ammonia container contains liquefied ammonia under pressure. The tubes containing hot water supplies heat to liquefied ammonia which evaporates and evaporated ammonia is supplied to chiller box. And hence refrigeration is created by vaporized ammonia in chiller box. Waste heat is heat, which is generated in a process by way of fuel combustion or chemical reaction, and then “dumped” into the environment even though it could still be reused for some useful and economic purpose. The essential quality of heat is not the amount but rather its “value”. The strategy of how to recover this heat depends in part on the temperature of the waste heat gases and the economics involved. Large quantity of hot flue gases is generated from Boilers, Kilns, Ovens and Furnaces. If some of this waste heat could be recovered, a considerable amount of primary fuel could be saved. The energy lost in waste gases cannot be fully recovered. However, much of the heat could be recovered and loss minimized by adopting following measures as outlined in this chapter. A waste heat recovery is an energy recovery system which recovers heat from hot streams containing high potential energy, such as hot flue gases from a diesel generator or steam from cooling towers or even waste water from different cooling processes such as in steel cooling or automobiles.
