Parametric evaluation of a new multigeneration based on advanced exergy

This paper deals with an advanced exergy analysis andoptimization of a multi-generation cycle. Theendogenous/exogenous exergy destruction parts of eachcomponent as well as their combinations withavoidable/unavoidable parts are determined. A parametricstudy is carried out to assess the sensitivity of totalavoidable exergy destruction. Parametric results reveal thatthe increment of upper m and P4 have a positive effect on theoverall system because the total real exergy destruction andunavoidable part reduce. It is concluded that the incrementof pressure has a negative effect on the components owingto the increase of real and unavoidable part of exergydestruction rate. In addition, the increase of TL3 has apositive effect on the avoidable part which provides thepossibility of improvement by reducing the irreversibilities.
