Abstract

An evaporation system and method having at least one fan operatively connected to drive means to effect fan rotation, at least one flow path to supply liquid to at least one nozzle to spray a mist of the liquid under centrifugal pressure. Velocity differential between the rotating nozzle(s) and airflow created by the at least one fan provides evaporation of the sprayed liquid. Inlet vanes direct airflow in a direction contra to fan rotation to increase velocity differential. The nozzles can be on fan blades and/or a central disc/hub. The method and system can be used for air conditioning, snow making, desalination or in industrial or commercial evaporators.
