Systems for water extraction from air

Abstract

A system for water extraction from air is provided. The system includes a housing having a plurality of openings allowing an air flow to enter into an inner space defined by the housing, a sponge disposed within the inner space defined by the housing, the sponge including a water absorbing/adsorbing material for absorbing/adsorbing water vapor from the air flow, and a water filter disposed below the sponge for filtering water discharged from the sponge.

         17 . A system for water extraction from air, comprising:
 a housing having a plurality of openings to allow an air flow to enter and exit an inner space defined by the housing;   a sponge disposed within the inner space defined by the housing, the sponge comprising at least one of a water absorbing material or a water adsorbing material; and   a presser disposed adjacent to the sponge, the presser being configured to move toward the sponge and compress the sponge to discharge water from the sponge during a water extraction process.   
     
     
         18 . The system of  claim 17 , wherein the housing comprises a heat insulation material. 
     
     
         19 . The system of  claim 18 , wherein the heat insulation material is disposed between an inner surface of the housing and an outer surface of the housing. 
     
     
         20 . The system of  claim 17 , wherein the housing includes an outer surface comprising a heat reflective material. 
     
     
         21 . The system of  claim 20 , wherein the heat reflective material comprises at least one of ceramic or aluminum. 
     
     
         22 . The system of  claim 17 , wherein the sponge comprises at least one of a tertiary amine, a polyethylene glycol, or hydrophobic activated carbon. 
     
     
         23 . The system of  claim 17 , wherein the presser is configured to compress the sponge without the sponge contacting the housing. 
     
     
         24 . The system of  claim 17 , further comprising a presser driver configured to move the presser. 
     
     
         25 . The system of  claim 24 , wherein the presser driver is configured to use human power to move the presser. 
     
     
         26 . The system of  claim 24 , wherein the presser driver is configured to use electrical power to move the presser. 
     
     
         27 . The system of  claim 24 , wherein the presser driver is configured to slide along a guiderail when the presser compresses the sponge. 
     
     
         28 . The system of  claim 17 , further comprising a water tank disposed to collect the water discharged from the sponge. 
     
     
         29 . The system of  claim 28 , further comprising a water filter disposed to filter the water prior to collection by the water tank. 
     
     
         30 . The system of  claim 17 , wherein the sponge comprises at least one of polymer, paper, or cotton fabric. 
     
     
         31 . The system of  claim 17 , the housing comprising:
 an inner wall;   an outer wall; and   flanges extending inwardly toward the inner wall from upper edges of openings on the outer wall.   
     
     
         32 . The system of  claim 17 , further comprising a fan configured to cause at least a portion of the air flow by rotating. 
     
     
         33 . A system for water extraction from air, comprising:
 a housing having a plurality of openings to allow an air flow to enter and exit an inner space defined by the housing;   a sponge disposed within the inner space defined by the housing, the sponge comprising at least one of a water absorbing material or a water adsorbing material; and   a fan configured to cause at least a portion of the air flow by rotating.   
     
     
         34 . The system of  claim 33 , wherein the housing comprises at least a heat insulation material or a heat reflective material. 
     
     
         35 . A system for water extraction from air, comprising:
 a housing having a plurality of openings to allow an air flow to enter and exit an inner space defined by the housing, the housing comprising:
 an inner wall; 
 an outer wall; and 
 flanges extending inwardly toward the inner wall from upper edges of openings on the outer wall; and 
   a sponge disposed within the inner space defined by the housing, the sponge comprising at least one of a water absorbing material or a water adsorbing material.   
     
     
         36 . The system of  claim 35 , wherein the housing comprises at least of a heat insulation material or a heat reflective material.
