Thermodynamic Analysis of a Trigeneration System Driven by an Internal Combustion Engine and a Steam Ejector Refrigeration System

This paper aims at studying a trigeneration system, based on an internal combustion engine and a steam ejector refrigeration system. The designed cycle is to generate cooling and heating energies, and supply power simultaneously. The cycle is studied from thermodynamics point of view and for this purpose, the first law of thermodynamics is applied to all the components of the cycle. The efficiency of the cycle is studied by changing a number of parameters such as the pinch point temperature, evaporator temperature, heat generator temperature, and condenser temperature to simulate summer and winter seasons. The results show an increase in the fuel efficiency up to 88% for the winter and 71% for the summer, and also a 28% fuel savings for the winter and 18% for the summer seasons.
