Systems and methods for generating water from air

A method for generating water comprising:

• directing a regeneration fluid in a closed-loop regeneration flow path 140 through a recuperative heat exchanger including:
• directing a first regeneration fluid flow through a hot-side layer located on a first side of a heat exchange plate;
• and,
• directing a second regeneration fluid flow through a cooling layer located on an opposing side of the heat exchange plate, the second regeneration fluid flow direction being generally counter to the first regeneration fluid flow direction;
• directing a cooling fluid through at least one pass in a cooling flow path located on the opposing side of the heat exchange plate;
• transferring heat through the heat exchange plate between the first regeneration fluid flow in the hot-side layer of the regeneration flow path and the second regeneration fluid flow in the cooling layer of the regeneration flow path;
• transferring heat through the heat exchange plate between the first regeneration fluid flow in the hot-side layer of the regeneration flow path and the cooling fluid in the at least one cooling layer;
• and,
• condensing water vapor from the first regeneration fluid flow.

A system for generating water from air comprising:

• a hygroscopic material configured to capture water vapor from air flowing in a process flow path during a loading operational mode;
• a thermal unit configured to heat the hygroscopic material and transfer water vapor released therefrom to a regeneration fluid flowing in a regeneration flow path during a release operational mode;
• a heat exchange assembly;
• a valve assembly comprising:
• a housing defining one or more flow channels having a flow channel axis;
• a slide plate movable transversely to the flow channel axis between a first position and a second position;
• an actuator configured to reciprocate the slide plate between the first position and the second position;
• wherein ambient air flowing in the process flow path is allowed to pass through the one or more flow channels in the first position, and the slide plate seals the flow channel in the second position.
