Patent ID: 8425660

Claim:
An apparatus for carrying out a method for extracting water from air, comprising: a rotatably mounted hygroscopic moisture-absorbing rotor having one region through which air can pass in the direction of thickness of said moisture-absorbing rotor; a passage for regeneration through which air for regeneration is circulated by heating with sunlight and which has openings at the opposing two surfaces of a regeneration region of said moisture-absorbing rotor, said regeneration region hung a part of said moisture-absorbing rotor, at which said moisture-absorbing rotor that absorbed moisture is regenerated; and a drain hole for taking out condensed water from said passage for regeneration, which is formed at a lower portion of said passage for regeneration, wherein said apparatus is useful in a method for extracting water from air comprising the steps of: directly and/or indirectly heating, with sunlight, said air for regeneration to be supplied to said regeneration region of said moisture-absorbing rotor so that said air for regeneration is circulated through said passage for regeneration and regeneration of said moisture-absorbing rotor occurs; cooling the air for regeneration after regenerating said moisture-absorbing rotor to condense moisture; and collecting the generated condensed water from said drain hole; said moisture-absorbing rotor being rotated so that said part of said moisture-absorbing rotor, which serves as said regeneration region, is changed.
