Importance of exergy for analysis, improvement, design, and assessment


Correspondence to: E-mail:


This study discusses what exergy analysis brings new to the system design, analysis, assessment, and improvement of energy systems. It also presents how efficiencies are defined for performance assessment. Case studies are given to explain how system exergy analysis is performed, and its efficiencies are evaluated for comparison. Exergy destruction rates for each component of the systems are also studied and presented to investigate the possibilities for determining the magnitudes and improving the performance.
