Abstract
The paper briefly discusses the theory and applications of the conventional and advanced exergetic analyses. A conventional exergetic analysis identifies the magnitude, location, and causes of thermodynamic inefficiencies. An advanced exergetic analysis evaluates the interactions among components of the overall system and the real potential for improving a system component and the overall system. The information supplied by an advanced exergetic analysis is very useful in understanding the operation of energy conversion systems and in developing strategies for improving them.
