Abstract
Provided herein are water harvesting systems, as well as methods using such systems, for capturing water from surrounding air. The systems and methods use water capture materials to adsorb water from the air. For example, the water capture materials may be metal-organic-frameworks. The systems and methods desorb this water in the form of water vapor, and the water vapor is condensed into liquid water and collected. The liquid water is suitable for use as drinking water.
Claims19
A water harvesting system for capturing water from surrounding air, comprising:
- a chamber, comprising:
- a plurality of plates,
- wherein each plate is independently coated on one or both sides with at least one water capture material,
- wherein the plates are arranged parallel to each other and a gap exists between adjacent plates, and
- wherein the at least one water capture material adsorbs water from surrounding air during an adsorption phase, and desorbs water in the form of water vapor during a desorption phase;
- at least one condenser positioned adjacent to one end of the plurality of plates, configured to condense water vapor into liquid water during a condensation phase;
- at least one gate valve configured to open during adsorption and close after adsorption;
- and
- at least one heat exchange manifold connected to, or positioned around, the plurality of plates, configured to heat up at least a portion of the plates, thereby causing desorption of at least a portion of water sequestered in the water capture material;
- at least one fan positioned adjacent to the plurality of plates at an end opposite to the at least one condenser, configured to blow air through the gap between adjacent plates towards the at least one condenser, thereby causing the at least one water capture material to adsorb water from surrounding air during adsorption;
- at least one vacuum pump connected to the chamber, configured to evacuate at least a portion of air out of the chamber when the at least one gate valve is closed;
- and
- a water storage tank, configured to receive the liquid water from the at least one condenser in the chamber.
