Abstract
This disclosure includes systems and methods for extracting water vapor from atmospheric air and, more particularly, but not by way of limitation, systems and methods for optimizing liquid water production from air, in some instances, taking into account diurnal variations. The systems comprise an adsorption zone and a desorption zone, an actuator to move a desiccant between the adsorption zone and the desorption zone. The liquid water production is optimized based, at least in part, on measurements of one or more of: an ambient air temperature, ambient air relative humidity, and a level of solar insolation.
Claims1
A system for generating water from air comprising:
- a hygroscopic material configured to be exposed to process air and a regeneration fluid;
- wherein the hygroscopic material captures water from process air and releases water to the regeneration fluid;
- a thermal unit configured to provide thermal energy to the regeneration fluid;
- a condenser configured to receive the regeneration fluid to produce liquid water from the regeneration fluid;
- a controller configured to control a liquid water production rate.
Dependencies are inferred from the claim text.
