Abstract:
1. An apparatus for producing, purifying and storing potable water from air comprising: a closed air passageway containing purified air; a heating unit in fluid contact with said purified air comprising a heating element, a temperature sensing unit and a controller, said controller having at least two temperature setpoints and a timing mechanism, at least one said temperature setpoint and time for normal operations and at least another said temperature setpoint and time for sterilization of said closed air passageway; an open air passageway containing filtered ambient air; a condensing unit comprising one or more condensing coils with inside surfaces and outside surfaces, said inside surfaces in fluid contact with said purified air, said outside surfaces in fluid contact with said ambient air; a water collecting unit comprising a tank in fluid contact with said inside surfaces of said condensing coils and a source of ultraviolet electromagnetic radiation immersed in condensate collected in said tank; a disposable water reservoir in fluid contact with said water collecting unit; a rotating mass of hygroscopic material comprising a hydrated portion and a dehydrated portion, said hydrated portion in fluid contact with said closed air passageway, said dehydrated portion in fluid contact with said open air passageway, adapted to periodically move each portion of said mass through both passageways wherein all portions will alternately pass from one said air passageway into another said air passageway, each portion alternating between a hydrated state and a dehydrated state and; a water purification unit comprising a refillable chamber, an input opening and an output opening, said input opening in fluid contact with said water collecting unit and said output opening in fluid contact with said disposable water reservoir, said chamber containing filter material suitable for use with potable water.
