ABSTRACT

 

The conventional approach followed for the evaluation of a coupled power-refrigeration cycle using the first law of thermodynamics is proposed to be substituted by analyzing it from the viewpoint of second law of thermodynamics. This paper describes that exergy clearly identifies efficiency improvements and reductions in thermodynamic losses paving the way for the adoption of green technologies. Exergy can be used to assess and improve energy systems by providing more useful and meaningful information than energy analysis. This article focuses on the development and state-of-the art of exergy analysis by leveraging conventional concepts. The thermodynamic models for energy and exergy analysis for computing performance parameters are presented in this paper.

 

Keywords : Energy, Exergy, Exergetic efficiency, Exergy destruction, Performance, Efficiency.
