In this paper, a trigeneration system is analyzed using an advanced exergy analysis. The trigenerationsystem is located in the Eskisehir Industry Estate Zone in Turkey. The exergy efficiency of the system wasfound to be 0.354, while the total exergy destruction rate of the system was 16.695 MW. The purpose ofthis study is to determine the improvement potential of the system. The exergy destruction within thecomponents of the facility is divided into four parts: endogenous, exogenous, avoidable and unavoidableexergy destruction. The components of the trigeneration system have strong relationships with eachother since the endogenous exergy destruction of the components is smaller than the exogenous exergydestruction. The avoidable exergy destruction rates are generally greater than the unavoidable ones.Thus, the trigeneration system possesses a high potential for improvement. This analysis indicates thatfrom a thermodynamic perspective, the turbo air compressor is the most important component in thesystem. Through the advanced exergy analysis, information about the relationships among the systemcomponents as well as the potential for further improvements may be provided in more detail
