Energy, exergy, and economic performance analysis of integrated parabolic trough collector with organic rankine cycle and ejector refrigeration cycle

This study presents a detailed energy, exergy, and economic analysis of an integrated solar power system combining a Parabolic Trough Collector, an Organic Rankine Cycle, and a Supercritical Carbon Dioxide Ejector Refrigeration Cycle. The goal is to assess the system's thermodynamic performance and economic viability, with an emphasis on optimizing efficiency and minimizing costs. A comprehensive thermodynamic model was used to evaluate the performance of key components, including the Parabolic Trough Collector, Organic Rankine Cycle turbine, Heat Recovery Vapor Generators, Recuperator, and Ejector. The findings reveal an energy efficiency of 25.1 % and an exergy efficiency of 12.67 %. The system's net power output is 258.9 kW, with a total exergy destruction of 2333 kW. The operational cost is 3.752 USD per hour, underscoring the economic considerations of the system. These results offer valuable insights that can guide the development of more sustainable and costeffective power generation technologies.
