Abstract
An atmospheric water generation system comprises water vapor consolidation systems configured to increase the relative humidity of a controlled air stream prior to condensing water from the controlled air stream. The water vapor consolidation system comprises a fluid-desiccant flow system configured to decrease the temperature of the desiccant to encourage water vapor to be absorbed by the desiccant from an atmospheric air flow. The desiccant flow is then heated to encourage water vapor evaporation from the desiccant flow into a controlled air stream that circulates within the system. The humidity of the controlled air stream is thereby increased above the relative humidity of the atmospheric air to facilitate condensation of the water vapor into usable liquid water.

A method for extracting water from air, the method comprising:
- flowing an air stream across a desiccant within an absorption chamber to extract water vapor from the air stream into the desiccant to form a water-rich desiccant;
- supplying the water-rich desiccant and a closed air stream to an evaporation chamber to extract water from the water-rich desiccant forming water-depleted desiccant and captured water vapor, wherein the captured water vapor is carried by the closed air stream to a condenser;
- and
- condensing the captured water vapor at the condenser into liquid water.
A method for extracting water from air comprising:
- pumping a water-depleted desiccant into an absorption chamber;
- flowing air into the absorption chamber;
- absorbing water into the water-depleted desiccant from the air to form water-rich desiccant;
- pumping the water-rich desiccant into an evaporation chamber;
- extracting water from the water-rich desiccant in the evaporation chamber in as water vapor;
- and
- condensing the water vapor into liquid water.
A system for extracting water from air comprising:
- an absorption chamber to extract water vapor from an air stream received at the absorption chamber into a desiccant to form a water-rich desiccant and water-depleted air;
- a carbon dioxide capture system, wherein the carbon dioxide capture system extracts carbon dioxide from the water-depleted air;
- an evaporation chamber to extract water from the water-rich desiccant to form water-depleted desiccant and captured water vapor;
- and
- a condenser to condense the captured water vapor into liquid water.
