Abstract: In this paper, a thermodynamic examination of novel solar-thermochemical assisted integrated system is designed for multigeneration purpose. This multigeneration system consists of six sub-systems that are the solar dish collector (SDC) system, double stage-organic Rankine cycle (DS_ORC), organic Rankine cycle (ORC), single effect absorption cooling (SEAC), hybrid magnesium chlorine (Mg-Cl) thermochemical system, and hydrogen liquefaction system. In this regard, the parametric study is given to examine how the whole thermodynamic performance integrated system are affected by way of various factors, such as reference temperature, solar irradiation, thermochemical reaction temperature, compression pressure. Furthermore, the overall energetic, exergetic performance and overall exergy destruction rate of multigeneration system are investigated. The exergy destruction rate and exergetic performance of Mg-Cl cycle are computed as 12,400 kW and 43.85%. Furthermore, the energetic and exergetic efficiency of overall multigeneration system are computed as 54.17% and 50.46%.
