Abstract: This article presents a novel Multiple Evaporation Desalination (MED) system, which uses water product to generate cooling through sudden expansion and condensation of cold vapor, due to the pressure increase caused by an ejector. The proposed system was simulated using Aspen Plus, proving its technical feasibility under different operating conditions. The desalination unit has 14 effects, is activated with a Top Brine Temperature (TBT) of 70 °C, generates 74,736.0 L/day of water, and 2043 kW (581 tons) of cooling. The proposed system has a Coefficient of Performance (COP) of 4.7, i.e. 6.53 times greater than a simple-effect absorption cooling system with a conventional COP of 0.72. Furthermore, it produces desalinated water with a Recovery Ratio (RR) of 0.53 and a Performance Ration (PR) of 11.96. For these reasons, the proposed system significantly increases the feasibility of MED technologies and generates large amounts of cooling, thus, having a great potential for use in all the coastal zones in the world.
