Claim 17:
18. A system to extract water from ambient air, the system comprising:
a thermal unit configured to heat a regeneration fluid in a regeneration fluid pathway;
a first desiccant unit configured to: receive ambient air in a process air pathway, and to receive the regeneration fluid from the regeneration fluid pathway;
a second desiccant unit configured to: receive ambient air during a load time, and, receive at least a portion of the regeneration fluid from the regeneration fluid pathway during a release time;
a vacuum pump configured to increase a partial pressure of water during the release time;
a valve configured to be actuated to increase a partial pressure of water during the release time;
a condenser unit configured to produce liquid water from the regeneration fluid; and,
a controller configured to control production rate of liquid water from air based on an operational parameter for water production, an ambient environmental condition, or combinations thereof.
