Abstract
A water harvesting unit may include a chamber and a vessel. The chamber may include a first plenum space and a second plenum space located on either side of a partition member. The vessel may be supported for rotation within the chamber. The vessel may include a base and a plurality of sidewalls. The plurality of sidewalls may extend from the base to a vessel opening. The base may be substantially fluid impermeable and at least a portion of the plurality of sidewalls may be fluid permeable. The base and a majority of the plurality of sidewalls of the vessel may be disposed in the first plenum space. The vessel opening may open to the second plenum space via an opening in the partition member.

A water harvesting unit, comprising:
- a chamber including a first plenum space and a second plenum space located on either side of a partition member;
- a vessel supported for rotation within the chamber, the vessel including a base and a plurality of sidewalls;
- wherein the plurality of sidewalls extend from the base to a vessel opening;
- wherein the base is substantially fluid impermeable and at least a portion of the plurality of sidewalls are fluid permeable;
- wherein the base and a majority of the plurality of sidewalls of the vessel are disposed in the first plenum space;
- and
- wherein the vessel opening is open to the second plenum space via an opening in the partition member.
A method of harvesting water from atmospheric air, the method comprising:
- passing a flow of atmospheric air through a rotating vessel, the vessel including a base and a plurality of sidewalls, the plurality of sidewalls extending from the base to a vessel opening, wherein the base is substantially fluid impermeable and at least a portion of the plurality of sidewalls are fluid permeable, the vessel further including a charge of particulate desiccant material disposed therein, wherein passing the flow of atmospheric air through the rotating vessel includes passing the flow through the plurality of sidewalls of the rotating vessel from an exterior of the vessel to an interior of the vessel, wherein the flow of atmospheric air exits the vessel via the vessel opening;
- stopping the flow of atmospheric air through the rotating vessel;
- passing a flow of desorption air through the rotating vessel, wherein passing the flow of desorption air through the rotating vessel includes passing the flow through the plurality of sidewalls of the rotating vessel from the exterior of the vessel to the interior of the vessel, wherein the flow of desorption air exits the vessel via the vessel opening;
- and
- cooling the flow of desorption air exiting the vessel to recover liquid water from the flow of desorption air.
