Configurable manifolds for water recovery device

摘要

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; and wherein 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.
