The exergetic analysis is a powerful tool for developing, evaluating and improving an energy conversion system.
The strengths and limitations of the so-called conventional exergetic analysis have already been discussed. An advanced exergetic analysis can significantly reduce some of the limitations of a conventional analysis by evaluating (a) the detailed interactions between components of the overall system, and (b) the real potential for improving a system component. The main objective of advanced exergy-based analyses is to provide engineers with additional useful information for better understanding and improving the design and operation of energy-conversion systems. This information cannot be supplied by any other approach. The weaknesses of an advanced exergetic analysis are associated with (a) the subjectivity that is associated with the calculation of avoidable exergy destruction and with the definition of both the ideal and the so-called hybrid processes, and (b) the large number of calculations that need to be conducted to obtain the avoidable endogenous and the avoidable exogenous values.
