Thermodynamic study of a trigeneration system based on solar energy

This thesis examines a solar-based multigeneration system comprising a PTC-collector, an ORC cycle, a single effect absorption refrigeration cycle, a PEM electrolyzer, and an RO desalination unit. The system produces power, cooling, hydrogen, and freshwater. The system undergoes thermodynamic analysis, which includes energy and exergy analysis. Various parameters' impacts are considered to study their effects on the system's efficiency. It is determined that the solar collector exhibits the highest exergy destruction rate among all the system's equipment. As the turbine inlet temperature rises, both the thermal and exergy efficiency of the system increase, along with the exergy destruction. When the turbine input pressure increases, the energy efficiency of the system declines, while the exergy efficiency of the system rises.
