  • Patent number: 10823436
    Abstract: In a process and apparatus of conditioning an airstream, the airstream is contacted with a liquid desiccant absorber in each of at least two stages. The same apparatus used as an evaporator to reconcentrate the desiccant. The desiccant for each said stage is cooled or heated externally to the absorber or evaporator using an external source of cooling supplied with a common cooling or heating fluid at each stage. The desiccant flows between the stages counter-current to the flow of the airstream such that at each step the concentration of the desiccant is reduced or increased by contact with the airstream so that the concentration in each stage is distinct from the concentration of the desiccant in the previous stages.

  • Patent number: 10583389
    Abstract: 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.

  • Patent number: 9518784
    Abstract: An indirect evaporative cooler for cooling inlet supply air from a first temperature to a second, lower temperature using a stream of liquid coolant and a stream of exhaust or purge air. The cooler includes a first flow channel for inlet supply air and a second flow channel adjacent the first for exhaust air. The first and second flow channels are defined in part by sheets of a membrane permeable to water vapor such that mass is transferred as a vapor through the membrane from the inlet supply air to a contained liquid desiccant for dehumidification and also to the exhaust air as heat is transferred from the inlet supply air to the liquid coolant. A separation wall divides the liquid desiccant and the coolant but allows heat to be transferred from the supply air to the coolant which releases water vapor to the counter or cross flowing exhaust air.

  • Patent number: 9297544
    Abstract: There is provided a humidification device capable of performing humidification in as short a time as possible when an indoor humidity is low. A humidification device includes operation control means for selecting either a humidification priority mode or a normal operation mode based on a predetermined condition to operate the humidification device, and fans that can adjust airflow rates, and generates airflow passing through a condenser and an evaporator, wherein operation in the humidification priority mode is operation in which the airflow rates of the fans are decreased, as compared with operation in the normal operation mode, by which desorption of moisture from an adsorbent of the condenser and collection of moisture by an adsorbent of the evaporator are promoted, as compared with operation in the normal operation mode, so that humidification is given priority over ventilation.

  • Publication number: 20150107287
    Abstract: An air conditioning system includes a dehumidifier, a regenerator, and a refrigeration system. The dehumidifier removes water from a first airflow using a liquid desiccant. The regenerator transfers water from the dilute desiccant into a second airflow. The refrigeration system can be selectively used to provide heat to the desiccant in the regenerator to more effectively remove the water from the dilute desiccant. An external heat source can also be used to heat the desiccant in the regenerator to more effectively remove the water from the dilute desiccant. The refrigeration system and the external heat source can each be used separately to heat the desiccant, or the desiccant can be heated by both heat sources simultaneously.
