Özet

In this study, a novel solar energy assisted multigeneration energy plant by using the solar radiation as a renewable energy resource is designed to produce some useful products, such as electricity, heating-cooling, and hydrogen, and modelled to increase the system performance. This designed multigeneration energy system consists of the solar power tower, steam Rankine cycles, absorption heating-cooling system, Cu-Cl thermochemical cycle, and hydrogen liquefaction unit. A thermodynamic assessment is developed by using the energetic and exergetic analyses to determine the irreversibilities of Cu-Cl thermochemical reaction-based integrated system at different working conditions. The energy and exergy performances of solar power assisted multigeneration system are computed as 22.21% and 14.02%. In the present study, the highest exergy destruction of this plant is determined for the solar power tower, and also, 5,738 and 4,812 kW of exergy destruction happens in the heliostat and central receiver, respectively. Moreover, the parametric works are carried out by changing the reference conditions and design indicators.
