Abstract


Fundamentals of exergy analysis in energy systems are reviewed and presented in a cohesive and general manner for the study of energy systems. The exergy analysis is applied to several engineering systems and processes, namely fuel cells, latent heat thermal energy storage, heat exchangers and thermal desalination systems to obtain insight on the best optimization strategies as well as the theoretical limits of performance. The various sources of irreversibility and optimal operating conditions are presented for relevant applications. It is also shown that for some systems the exergy efficiency as a function of a given parameter may have opposite trend than the first law efficiency.
