Exergoeconomic Performance Assessment of a Trigeneration System Based on Solid Oxide Fuel Cell
In this study, a hybrid system including of a solid oxide fuel cell cycle, a domestic hot water heat exchanger and a single-stage water-ammonia absorption chiller are simulated for the simultaneous generation of power, cooling and hot water. , and it is examined from the perspective of energy, exergy and exergy-economic. After evaluating the results in the base input mode, the effect of changing the fuel cell flow density and fuel consumption coefficient on the system performance is investigated. The basic shows that overall work is 4,418 kW, the total irreversibility is 1,650 kW and the overall exergy efficiency is 378/0. Also, the air heat exchanger, water heat exchanger and fuel cell are introduced as components that should be considered more than other components from the exergy-economic point of view, since they are almost the largest amount of cost pertaining to these components
