VAPOUR ABSORPTION SYSTEM USED IN AUTOMOBILE AIR CONDITIONING
[attachment=35329]
ABSTRACT
In this investigation; analysis and design of an automobile air conditioner was made by utilizing the available diesel engine exhaust waste energy to provide the required heat for the generator. Because automotive air conditioning is one of the most equipment that heavily uses CFC compounds, and the leakage of CFCs from such air conditioners affect the environment, the absorption cycle was found to be an ideal option. Cooling load for the automobile has been estimated and found to be within acceptable ranges which are about 1.37 TR. The reported results show that the COP values directly proportional with increasing generator and evaporator temperatures. Measured COP values of the proposed model varied between 0.85 and 1.04.
The generator was designed and fabricated for optimal performance and could be rapidly transfer to the industrial applications, The system was found to be applicable and ready to produce the required conditioning effect without any additional load to the engine The proposed system decreases vehicle operating costs and environmental pollution caused by the heating system as well as causing a lower global warming. Simple experiments were carried out to examine the performance of the generator heat shown the benefit of exhaust gases as an alternative heating source.
