Thermodynamic analysis of solar tower collector integrated with steam Rankine cycle, organic Rankine cycle and absorption refrigeration cycles for cogeneration of power and cooling

A configuration of solar tower collector is developed to drive the proposed system integrated with steam Rankine cycle (SRC), organic Rankine cycle (ORC), and two absorption refrigeration cycles (ARCs) for power and cooling, and a thermodynamic analysis is performed. A detailed assessment of energy and exergy issues has been conducted in this paper. Results show that this study found the thermal efficiency of the system to be 70.87% for R123, 70.79% for R245fa, and 72.57% for toluene. Additionally, the exergy efficiency was obtained at 21.82% for R123, 21.51% for R245fa, and 28.79% when toluene is used as a working fluid.
