| description | The increasing global demand for sustainable energy and potable water necessitates efficient energy conversion technologies. Co-generation systems, which simultaneously produce electricity and desalinated water, represent a promising solution for fulfilling the essential needs of urban areas and localized facilities, such as sports complexes. This study evaluates a co-generation system designed to provide energy and potable water for a specific sports complex. The thermodynamic cycle was simulated utilizing validated numerical methods, solving the governing equations governing the system's operation. Multi-objective optimization, based on the Pareto Front methodology, was implemented to enhance overall system performance and minimize environmental impact. A comprehensive life cycle environmental assessment was performed using exergo-environmental analysis. Baseline simulations indicated a power output of 1441 kW, alongside a desalinated water production rate of 1.392 m3/h. These values correspond to an initial energy efficiency of 71.8 % and an exergy efficiency of 41.64 %. Following the multi-objective optimization procedure, guided by the Pareto Front, the system performance was notably improved. The energy efficiency increased to 72.13 %, and the exergy efficiency reached 44.92 %. Furthermore, the exergo-environmental (Ɛes) exhibited a marked improvement, achieving a value of 0.964, signifying a reduced environmental burden. The results underscore the potential of optimized co-generation systems to enhance energy efficiency and sustainability. |
