The Study of Solar Desalination System with Falling Film Evaporation and Its Operation

The seawater desalination system with falling film evaporation was set up, which was driven by solar-wind energy. In addition, the basic principles of system operation were expounded, and the main factors affecting the system performance were discussed. The results showed that the latent heat of vapor and the heat of brine were utilized repeatedly in the system. In addition, the system had a higher performance coefficient, which had good transient and steady-state performance of producing freshwater.
