Abstract

This study presents a comprehensive simulation study focusing on the thermodynamic design and exergoeconomic analysis of a solar-powered tri-generation system, which uses energy to produce electricity, heating, and cooling (CCHP) in Antalya, Turkey. The system integrates parabolic trough collectors in which Therminol 66 is the heat transfer fluid to power an organic Rankine cycle engine and an absorption refrigeration unit. The analysis used an EES model based on the Engineering Equation Solver under steady-state conditions. Energy, exergy, and exergoeconomic evaluations were carried out to assess the system's performance that has R245fa and butane within the organic Rankine cycle as working fluids. A parametric analysis examined the effects of superheating degree, turbine pressure, and level of solar beam irradiation on different outputs, including power generation, heating and cooling outputs, thermal and exergy efficiency, and total cost rates. Results showed that the R245fa-based system achieved an electrical output of 232.5 kW, a cooling capacity of 716.7 kW, a heating capacity of 2225 kW, a thermal efficiency of 86.89%, an exergy efficiency of 16.26%, a total cost rate of 66.12 $/h, and a carbon footprint of 0.195 kg CO_2/kWh. Additionally, the exergoeconomic factor for this system was 72.12%. On the other hand, the butane-based system produced 221.8 kW of electricity, 745.4 kW of cooling, and 2197 kW of heating, with a thermal efficiency of 86.44%, an exergy efficiency of 15.73%, a total cost rate of 63.06 $/hour, and a carbon footprint of 0.223 kg CO_2/kWh. The exergoeconomic factor for the butane-powered system was calculated at 70.86%.
