Patent ID: 8858684

Claim:
A method of recovering water vapor from ambient air, the method comprising: providing a water recovery device including (i) a desiccant stack having a chamber defining an airflow path therein, the desiccant stack including a plurality of desiccant trays, each desiccant tray including a desiccant media cartridge and an amount of liquid desiccant placed within the tray and absorbed by a media material of the media cartridge; (ii) a condenser communicating with the desiccant stack; and (iii) a heat exchanger communicating with the desiccant stack for providing heat to the desiccant stack; operating the water recovery device in a charge cycle, wherein the ambient air is circulated through the chamber to remove water vapor by the liquid desiccant and retaining water vapor in the chamber; further operating the water recovery device in an extraction cycle to remove the retained water vapor within the chamber; and condensing the water vapor by a cooling source within the condenser thereby producing an amount of water condensate.
