چکیده مقاله :
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 components of the cycle. The efficiency of the cycle is studied by changing parameters such as the pinch point temperature, evaporator temperature, heat generator temperature, and temperature of condenser to simulate summer and winter seasons. The results show an increase in the fuel efficiency up to 88% in winter and 71% in summer, and also a 28% fuel savings in winter and 18% in summer.
