Abstract:
1. Apparatus for extracting potable water from air comprising: a) a closed loop air passage duct; b) air movement apparatus disposed within said air passage duct for circulating air in a predetermined direction through said duct thereby creating a continuous flow of circulating air within said air passage duct; c) means for introducing water into said continuously circulating air flow to form water vapor so that upon evaporation of said introduced water, adiabatic cooling and an increase in absolute humidity of said air flow occurs downstream of said water introducing means; d) a first cooling element having a surface disposed within said duct down stream of said water introducing means, said first cooling element operating at a temperature at or below the dew point of said adiabatic cooled air flow, thereby causing collectible liquid water to form on said surface of said first cooling element as said continuous flow of air passes over said surface of said first cooling element; and e) first heating means disposed within said continuous air passage duct downstream of said first cooling element for increasing the temperature of said flow of air previously cooled by contact with the surface of said cooling element, thereby decreasing the relative humidity of said air flow as it is returned to said air movement apparatus.
