چکیده

The research focuses on evaluating the energetic and exergetic sights of a newly developed multigeneration system utilizing geothermal energy and PVT solar collectors to create electricity, cooling, heat, hydrogen, and fresh water. This setup includes an organic Rankine cycle, a single-effect absorption chiller, a heat pump, a RO desalination unit and a PEM electrolyzer. The EES software was utilized to analyze thermodynamic and various parameters. Findings indicate that the system achieves energetic and exergetic outcomes of 10.29% and 36.77%, respectively. The net power output of the system totals 2004.86 kW, primarily driven by the ORC turbine. In addition, the cooling system realizes energetic and exergetic COPs of 0.54 and 0.22 based on the specified hypothesis. The system generates hydrogen at a daily rate of 796.8 kg and freshwater at a rate of 5.52 kg/s. Exergy destruction rate analysis reveals that the organic Rankine cycle suffers the most significant exergy loss.
