Multi-production is a practical approach to boost the efficiency of energy conversion sys-
tems by utilizing waste energy to producing more commodities in comparison to con-
ventional single output plants. Solar energy is a vast source of energy that has the potential
to be employed for different purposes. Therefore, in this research, a solar-driven multi-
production system of power, cooling, and hydrogen generation is proposed and evaluated
for being implemented in the city of Bandar-Abbas. The overall system is evaluated by
calculating the exergy efficiency and exergy destruction rate of each equipment of the
multi-production system. Based on the obtained results, heat exchangers, valves and
drums, and splitters monitor to be the most exergy destructive equipment compared to
other equipment in the multi-production system. In overall, the designed multi-production
system reaches the overall energy efficiency of 90.77% and the overall exergy efficiency of
92.19%. In addition, the coefficient of performance is 0.39 for the absorption refrigeration
cycle of the designed multi-production system. In overall, the designed system is able to
produce 4.36 MW of electricity, 1.65 MW of cooling load, and 2026 kg/h of hydrogen gen-
eration at 80.86C and 2068 kPa.
