Summary

The present paper presents a numerical model to analyze the thermal and fluid dynamic behavior of a mechanical vapor compression MVC desalination system. The MVC desalination is a method to obtain distilled water using the evaporation and condensation processes at the same time, both occur at low pressure (values lower than atmospheric pressure). This method requires a compression work to increase the saturation temperature of the vapor mass flow obtained in the evaporator, which is used to feed the condenser. Then, the compressed vapor is condensed, and its latent heat is transferred to the feed seawater. The numerical modeling is applied to analyze the thermal and fluid dynamic behavior of a MVC desalination system, using renewable energy source (solar energy) to supply the electric requirements of the system. The electrical energy is used to feed the mechanical compressor, a heater, a group of pumps and the control panel of the system. The numerical model has been validated using experimental data obtained from the technical literature, presenting a good agreement. The performance system analysis has been carried out considering the variability of renewable sources, while the influence of the boundary conditions on the execution of the unit along the time is also analyzed, showing the capabilities of the present model.
