Abstract: Throughout present research, an optimization investigation of an irreversible refrigeration absorption system on the basis of a new thermo-ecological criterion. The objective functions which considered are the specific entropy generation rate and the ecological coefficient of performance (ECOP). Two objective functions of the ecological coefficient of performance and the specific entropy generation rate are optimized simultaneously using the multi-objective optimization algorithm NSGAII. ECOP has been maximized and specific entropy generation rate is minimized in order to get the best performance. Decision making has been done by means of two methods of LINAMP and TOPSIS. Finally, sensitivity analysis and error analysis was performed for the system.

Keywords: Refrigeration system; specific entropy generation rate; ecological coefficient of performance; optimization; NSGAII; Decision making
