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.

A dialysis system (e.g., a hemodialysis (HD) system) can be designed to operate in alternative environments, such as disaster relief settings or underdeveloped regions. The dialysis system can include a solar panel for generating electricity to power the dialysis machine and an atmospheric water generator for extracting water from ambient air. The extracted water can be used to generate dialysate and saline on-site. One or more of the components of the dialysis machine can be discrete components that are configured to facilitate fast shipping and simple on-site assembly (e.g., at a remote location). In some implementations, the discrete components may be configured to be attached to an existing dialysis system (e.g., a dialysis system designed for operation in a traditional environment) to permit the dialysis system to operate in an alternative environment.

A fluid dynamic rain-making apparatus includes a first tubular member (10) and a thermal conductor (20). The first tubular member (10) includes a fluid channel having a first opening (12) and a second opening (13). An axial cross section of the fluid channel (11) decreases from the first opening (12) toward the second opening (13). The thermal conductor (20) includes a second tubular member (21) attached to the second opening (13) of the first tubular member (10) and heat sinks (22) circumferentially arranged on an outer surface thereof. A fluid (A) enters the fluid channel (11) from the first opening (11) and forms a cooled fluid (A1) through flowing through the fluid channel (11) for cooling the second tubular member (21), thus the heat sinks (22) are cooler than the external fluid (A). Accordingly, moist air is cooled to reach the dew point to form water drop for rainfall.

Apparatus for producing liquid water from the condensation of atmospheric water vapor includes a transportable housing defining a first air inlet, a second air inlet, and an air outlet; first and second doors operable selectively to open and close the first and second air inlets, respectively; and at least one water condensation unit located in the housing between the first air inlet and the air outlet, and between the second air inlet and the air outlet. The housing is configured so that, when at least one of the first and second air inlets is open, at least a portion of an air flow into the at least one open air inlet is passed through the at least one condensation unit and out the air outlet.

Atmospheric moisture harvester systems include two beds with water capture material, such as metal-organic framework (MOF), a heater, two fans, and a condenser having two sides, operatively configured into adsorption and desorption modes, wherein the MOF beds are interchangeable to cycle between the desorption and water adsorption modes. The systems may further include a photovoltaic panel powering the fans and condenser.

An atmospheric water generation system comprises water vapor consolidation systems configured to increase the relative humidity of a controlled air stream prior to condensing water from the controlled air stream. The water vapor consolidation system comprises a fluid-desiccant flow system configured to decrease the temperature of the desiccant to encourage water vapor to be absorbed by the desiccant from an atmospheric air flow. The desiccant flow is then heated to encourage water vapor evaporation from the desiccant flow into a controlled air stream that circulates within the system. The humidity of the controlled air stream is thereby increased above the relative humidity of the atmospheric air to facilitate condensation of the water vapor into usable liquid water.
