Heat recovery, Electrolux refrigeration system.


Efficiency of diesel engine is about 35-40 % remaining energy go waste. Maximum energy wastes in exhaust. In diesel engine 30-32% energy go waste in exhaust. So it is important to recover energy from exhaust. Approximately 15% of all the electricity produced in the whole world is employed for refrigeration and air conditioning system. During recent years research aimed at the development of technologies that can offer reductions in energy consumption, peak electrical demand and energy costs without lowering the desired level of comfort conditions has intensified. By reason that absorption refrigeration technologies have the advantage that the peaks of requirements with the availability of the waste heat. A 15 kW internal combustion engine was analyzed experimentally to determine whether it was capable of driving the experimental refrigeration system via its exhaust heat. This required a study of heat distribution of the diesel engine under various load conditions. As far as the integrated system is concerned, the experiments were focused on the heat distribution of the diesel engine and effect on the performance of the absorption refrigeration system. At full load condition, performance of refrigeration system is higher because of higher exhaust gas temperature. If more heat recovered from the exhaust gas of the IC engine then more heat transferred to the generator and hence this caused an increase on the cooling capacity of the experimental refrigeration system. This is due to the fact that, in the refrigeration system, the cooling capacity is directly proportional to the heat input to the generator.
