Energy and exergy evaluation of the new cycle of cogeneration power, heating, cooling and seawater desalination system by multi-effect distillation and reverse osmosis methods

In this study, a new cycle of cogeneration power, heating and cooling integrated with fresh water production system by multi-effect desalination method and solar system has been evaluated. Energy and exergy analyzes have been used to evaluate system performance. In order to generate power, the gas cycle has been used as the main stimulus and the organic Rankin cycle has been used as the downstream cycle. The results of this study show that due to the addition of the solar system in the vicinity of the organic Rankin cycle, the increase of the organic Rankin cycle efficiency improves from 38.778% to 44.592% to 5.813%. In addition, at constant cooling rates, the cooling performance increased by 1.275 percent from 1,596 to 1,617. Also, due to the high production capacity of the gas turbine cycle compared to the production capacity of the Rankin cycle, the addition of the solar system to the base cycle (without the solar system) increases the thermal efficiency and exergy by 0.638 and 0.085%, respectively. Also, distillate flow rate increases 726.8 Ton/h by using reverse osmosis system.
