Energy, Exergy, and Economic Analysis and Optimization of Novel Multi-generation System with Combination of Heat Recovery Exchanger and Absorption Transformer

This evaluation presents a new multi-generation system that incorporates a gas turbine, an appropriate transformer, a cogeneration system, and a heat exchanger for generating electricity along with heating and cooling capabilities. A comprehensive analysis of the system's thermodynamic and economic performance has been conducted. The waste heat from the gas turbine is captured and utilized to generate additional electricity within the turbine, while cooling capacity is achieved by recovering heat from the absorption transformer. Among the assessment techniques used, the application of cutting-edge technology enhances cost efficiency, resulting in improved economic effectiveness across various production systems. A sensitivity analysis was also performed to assess how the system responds to different conditions. Additionally, a two-objective genetic optimization algorithm was employed to identify the optimal solutions. The thermodynamic assessment indicates that the proposed system achieves an energy efficiency of ۲۱.۲۹% and an exergy efficiency of ۲۰.۶۸%. The analysis reveals that the system's cooling capacity is ۲,۷۴۶ kW, while the total exergy destruction within the system is ۲,۴۰۹ kW. The system is expected to produce a heating load of ۲,۹۲۱ kW and an output power of ۳,۸۷۴ kW. The economic analysis shows that with a total cost of ۹۳.۵۶ /s and a combined investment and maintenance cost of ۱,۷۳۲ /s, the proposed system is highly cost-effective.
