Energy and Exergy Analysis of Engine Exhaust Driven Vapour Absorption Refrigeration System 2012-28-0026
Lot of waste heat in the temperature range 350-400°C is available from I.C. engine exhaust. The same can be utilized for the operation of a triple effect absorption system which requires heat from a high temperature heat source. In this paper, the energy and exergy analysis of series flow triple effect water-lithium bromide absorption systems is presented assuming engine exhaust as a heat source. A computational model has been developed for the parametric investigation of the system. The analysis involves the determination of effects of generator and absorber temperatures on the energetic and exergetic performance of the system. The performance parameters computed are coefficient of performance, exergetic efficiency and the cooling capacity.
