A system and method to recover water from an ambient airstream. Dehumidification of the airstream is also achieved by removal of the water. A device of the system includes a chamber having a group of trays that hold respective amounts of liquid desiccant in each tray. Fans, valves, and manifolds are used to control airflow through the device. A charge cycle circulates air through the device to remove water vapor from the airstream. A subsequent extraction cycle removes water collected in the liquid desiccant by a condenser communicating with the chamber. The airflow within the chamber and/or each tray is altered depending upon the settings of configurable airflow manifolds. An integral heat exchanger adds heat to the chamber during the extraction cycle. A controller is used to integrate and manage all system functions and input variables to achieve a high efficiency of operational energy use for water collection.

1. A water recovery device comprising: a desiccant stack including a stack chamber, the desiccant stack further including one or more desiccant containers, each desiccant container having a container chamber and a desiccant media cartridge disposed within the container chamber, wherein an amount of liquid desiccant is at least partially absorbed by a media material of the media cartridge, each desiccant container including a manifold with a plurality of openings that direct and define an airflow path within the stack chamber; andwherein the airflow path within the stack chamber is configurable by controlling an airflow communication between each desiccant container in the desiccant stack via the plurality of openings. 2. The water recovery device, as claimed in claim 1, wherein the desiccant container is a desiccant tray, and one or more desiccant trays are stacked on a first desiccant tray. 3. The water recovery device, as claimed in claim 2, wherein: the first desiccant tray has a first plurality of openings of a first size and a second desiccant tray has a second plurality of openings of a second different size. 4. The water recovery device, as claimed in claim 2, wherein: at least one of the plurality of openings is a configurable opening, and said configurable opening is positioned at least at one of an open, closed, partially open, and partially closed position. 5. The water recovery device, as claimed in claim 4 further including: a controller operatively connected to said at least one configurable opening, wherein said controller directs said at least one configurable opening to said at least one of the open, closed, partially open and partially closed position. 6. The water recovery device, as claimed in claim 5, wherein: at least one setting of the at least one configurable opening is received at the controller. 7. The water recovery device, as claimed in claim 2, wherein: the airflow path within the stack chamber is defined by orienting the desiccant tray with respect to another desiccant tray within the desiccant stack. 8. The water recovery device, as claimed in claim 7, wherein: the airflow path through the stack chamber is substantially tortuous. 9. The water recovery device, as claimed in claim 2, wherein: an airstream is circulated through the stack chamber, the airstream taking a directed flow path through the stack chamber that includes at least one of a serial flow path, and a parallel flow path. 10. The water recovery device, as claimed in claim 2, wherein: each desiccant tray includes a plurality of sidewalls, a base, and a plurality of configurable openings, the plurality of configurable openings being disposed in at least one of the plurality of sidewalls. 11. The water recovery device, as claimed in claim 10, wherein: one or more of the plurality of configurable openings are operable to direct a flow path of an airstream through the stack chamber and away from the desiccant media cartridge in at least one desiccant tray. 12. The water recovery device, as claimed in claim 10, wherein: in response to a change in at least one of the plurality of configurable openings, an airstream circulated through the stack chamber in a substantially serial flow path changes to an airstream circulated through the stack chamber in a substantially parallel flow path. 13. The water recovery device, as claimed in claim 12, wherein: the at least one of the plurality of configurable openings is configured to change in response to receiving an instruction from a controller. 14. A water recovery device comprising: a desiccant stack including a chamber defining an airflow path therein, the stack including a plurality of desiccant trays, each tray including a plurality of openings that direct and define a flow path within the chamber, each desiccant tray further including a desiccant media cartridge and an amount of liquid desiccant placed within the tray and being absorbed by a media material of the media cartridge;a condenser communicating with the desiccant stack;a heat exchanger communicating with the desiccant stack for providing heat to the desiccant stack;wherein the water recovery device is operated in a charge cycle for circulating ambient air through the chamber to remove water vapor by the liquid desiccant and retaining water vapor in the chamber, the device being further operated in an extraction cycle to remove the retained water vapor within the chamber, the condenser providing a cooling source to condense the water vapor and thereby producing an amount of water condensate. 15. The water recovery system, as claimed in claim 14, wherein: a first desiccant tray has a plurality of openings of a first size and a second desiccant tray has a plurality of openings of a second different size. 16. The water recovery device, as claimed in claim 14, wherein: at least one of the plurality of openings is a configurable opening, said configurable opening is positioned at least at one of open, closed, partially open, and partially closed positions. 17. The water recovery device, as claimed in claim 14, wherein: an airflow path within the chamber is defined by orienting a desiccant tray with respect to another desiccant tray within a stack of desiccant trays. 18. The water recovery device, as claimed in claim 14, wherein: each desiccant tray includes a plurality of sidewalls, a base, and a plurality of configurable openings, the plurality of openings being disposed in a plurality of sidewalls; andone or more of the plurality of configurable openings are operable to direct a flow path of an airstream through the chamber away from flowing past a desiccant media in at least one desiccant tray. 19. A water recovery system comprising: (a) a water recovery device including: (1) a desiccant stack including a chamber defining an airflow path therein, the stack including a plurality of desiccant trays, each tray including a plurality of openings that direct and define a flow path within the chamber, each desiccant tray further including a desiccant media cartridge and an amount of liquid desiccant placed within the tray and being absorbed by a media material of the media cartridge;(2) a condenser communicating with the desiccant stack;(3) a heat exchange communicating with the desiccant stack for providing heat to the desiccant stack;wherein the water recovery device is operated in a charge cycle for circulating ambient air through the chamber to remove water vapor by the liquid desiccant and retaining water vapor in the chamber, the device being further operated in an extraction cycle to remove the retained water vapor within the chamber, the condenser providing a cooling source to condense the water vapor and thereby producing an amount of water condensate;(b) a controller incorporated in the device for controlling functioning of the device to include the charge cycle and the extraction cycle, the device further including a plurality of sensors as inputs to the controller, and a plurality of valves and fans as outputs of the controller, the valves and fans being located within air transport lines of the device; and(c) said water recovery device further including a communications node incorporated within a communication system enabling the water recovery device to communicate within the communications system. 20.
