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.

Provided is a condensation device capable of removing water vapor from a larger amount of gas without making a size larger than in related art. A condensation device 700 according to the present invention includes an outer cooling unit 720 including one or two or more inner tubes 722, an outer tube 724 located outside the one or two or more inner tubes 722, and a first flow path 726 through which a first cooling medium passes between the one or two or more inner tubes 722 and the outer tube 724.

A cooling system utilizes an organic ionic salt composition for dehumidification of an airflow. The organic ionic salt composition absorbs moisture from an inlet airflow to produce an outlet airflow with a reduce moisture from that of the inlet airflow. The organic ionic salt composition may be regenerated, wherein the absorbed moisture is expelled by heating with a heating device. The heating device may be an electrochemical heating device, such as a fuel cell, an electrochemical metal hydride heating device, an electrochemical heat pump or compressor, or a condenser of a refrigerant cycle, which may utilize an electrochemical pump or compressor. The efficiency of the cooling system may be increased by utilization of the waste heat the cooling system. The organic ionic salt composition may circulate back and forth or in a loop between a conditioner, where it absorbs moisture, to a regenerator, where moisture is desorbed by heating.

A scraped heat exchanger apparatus, including a vessel and a plurality of internally cooled plates disposed parallel to each other within the vessel. A rotating shaft is disposed at a central axis of the vessel. A rotating scraper arm, connected to the rotating shaft, moves between adjacent plates. The rotating scraper arm includes a scraper positioned to scrape solids from the outer surfaces of adjacent plates. A cooling fluid flows through an interior of each plate. The cooling fluid cools a gaseous process fluid flowing between adjacent plates. An opening in each of the plates permits the process fluid, and solids removed from the process fluid and scraped by the rotating scraper arm, to pass through the plates.

An atmospheric water harvesting generator includes an adsorbent with a nanopore structure and a moisture-condensing substrate with an amphiphilic structure such that water can be efficiently harvested from the atmosphere even in a dry climate, the generator is easy to operate with little power, and the flow of air can be controlled with a simple control to efficiently and continuously harvest water.

Cooling a first device and second device in a fashion to produce water. The method includes collecting environmental air from an environment. The environmental air is used to cool a first device. Cooling the first device generates first device exhaust air produced from the environmental air. The first device exhaust air is provided to a first device portion of a heat exchanger. At a second device portion of the heat exchanger, thermally coupled to the first device portion of the heat exchanger, second device exhaust air generated by cooling a second device is received. At the heat exchanger, the first device exhaust air is used to cool the second device exhaust air to a dew point, causing condensed water to be created from the second device exhaust air. The condensed water is collected.
