Exergy Analysis of a Trigeneration System Driven by an Internal Combustion Engine with a Steam Ejector Refrigeration System

The present study analyzes a trigeneration system based on an internal combustion engine and a steam ejector refrigeration system from an exergy point of view. the present system is to produce cooling energy, heating energy and to supply power simultaneously. the analyses include a thorough implementation of the first law of thermodynamics and exergy formulations on each and every component of the designed cycle. having computed the system exergy, the system exergy destruction sources are determined for both the summer and winter seasons. based on the exergy analyses, about 360 kw by the internal combustion engine and about 70 kw by the steam generator are found to be the main exergy destruction sources in the cycle. furthermore the heat generator and heat exchanger within the proposed cycle show to produce the maximum and minimum amount of exergy, respectively.
