The main productions of this system is power, hot water, cooling,  hydrogen and freshwater. The introduced system included the Rankine cycle, the double effect organic refrigeration system, the PEM electrolyzer and the RO desalination unit. The EES software was used to analyse energy, exergy, thermoeconomics and a range of parameters. As the results show, the highest amount of exergy destruction is associated with the PTC collector, ORC cycle and PEM electrolyzer, according to the exergy destruction analysis of the main cycles. The rise in the collector area, solar radiation and ORC turbine inlet temperature leads to higher levels of hydrogen and freshwater production. Moreover, investigating different working fluids in the ORC cycle proves that R141b shows the best performance from point of view of hydrogen and freshwater production rates. Furthermore, 33.49% and 13.31% are found for the energetic and the exergetic performance of the system, respectively. https://hfe.irost.ir/article_1435_1f3202d820180a39f736f20fce790de8.pdf
