| Background and Objective Infrastructure services, e.g., industrial and domestic sectors, military, education, and agriculture, were highly impacted by the manner of energy management, its economics, and environmental impact. Nowadays, although conventional energy conversion-based systems are not appropriate to address energy management and meet the global energy demand, principal efforts have been made by researchers and active companies. Hence, with a variety of use, renewable energy-based high-temperature applications that introduce an alternative option to conventional fuels are currently available thanks to the newly created systems. Materials and Methods The framework of the simulation has been accomplished through writing code in the engineering equation solver (EES) software as the thermodynamic- and heat transfer-based tool. Also, the GWO method has been applied to the calculations through MATLAB software. Findings Considering the necessity of producing freshwater from seawater, especially in regions with high solar energy potential, this study proposes a novel system for tri-generation application using solar power through which high capability of freshwater production is available together with electricity and cooling. This system comprises a heliostat field and a phase change material storage unit for continuous production, a gas turbine cycle, a Kalina cycle, an absorption chiller, and a humidification the system has been accomplished utilizing a comprehensive parametric study and environmental analysis; afterward, the method of grey wolf optimization has been utilized to optimize the simulation in different multi-objective cases. Regarding obtained results, the net power generation is obtained of about 4137 kW and 41.28 kg/s freshwater with 30.63% exergetic efficiency and 57.55 $/GJ unit product cost. Also, applying the optimization declines the freshwater production rate, but it improves the other performance indexes. The optimization scenarios comparison reveals that the exergetic efficiency/unit product cost scenario has the best overall results where it provides 32.90% exergetic efficiency and 48.98 $/GJ unit product cost and results for environmental sustainable index and Exergoenvironmental impact index becomes 1.629 and 1.84 respectively. Conclusion Using this proposed system provides fresh water, power and cooling by the mean time improves energy and exergy efficiency and reduces negative environmental impacts. |
