Abstract: Systems and methods for operating a water recovery system and include activating a plurality of dampers, a fan, and a refrigeration system of the water recovery system. The method includes measuring an ambient air temperature of the water recovery system based on data obtained from an ambient air temperature sensor. The method includes measuring one or more evaporator temperatures associated with an evaporator of the water recovery system based on data obtained from one or more evaporator temperature sensors. The method includes determining an optimal evaporator air temperature of the water recovery system based on the one or more evaporator temperatures and the ambient air temperature. The method includes setting a speed of the fan of the water recovery system based on the optimal evaporator air temperature.

Abstract: Systems and methods are disclosed and include a controller and a water recovery device. The water recovery device includes a desiccant stack including a chamber defining an airflow path therein. The water recovery device includes an evaporator in communication with the desiccant stack and one or more condensers in communication with the desiccant stack. The controller is configured to set the water recovery system to one of an absorption mode and an extraction mode. The water recovery device is configured to receive ambient air in the chamber to remove water vapor using the liquid desiccant and retain the water vapor in the chamber when the water recovery system is in the absorption mode. The water recovery device is configured to remove the water vapor within the chamber when the water recovery system is in the extraction mode.

Abstract: Systems and methods for operating a water recovery system are described and include activating a condenser of the water recovery system. The method includes measuring a temperature associated with the condenser based on data obtained from a condenser temperature sensor. The method includes comparing the temperature associated with the condenser to a maximum threshold temperature. The method includes activating an auxiliary condenser of the water recovery system in response to the temperature associated with the condenser being greater than the maximum threshold temperature.
