Humidity control unit and method having bypass for process air
In conditioning air for an enclosure, a first ambient airstream is cooled by the cooling coil of a refrigerant cooling system to reduce its temperature and humidity content. The thus cooled and dehumidified air is then passed through a segment of a rotating desiccant wheel to reduce moisture content and increase temperature and is then supplied to the enclosure. The desiccant wheel is regenerated by the use of a second ambient airstream which is first heated with the condenser coil of the refrigerant system and then passed through the regeneration segment of the desiccant wheel. A bypass plenum is provided in the apparatus that selectively allows a third ambient airstream to be cooled in the plenum independent of the evaporator coil and desiccant wheel in the first plenum. That airstream is then supplied with the air treated in the first plenum to the enclosure.

A water extraction method and moisture extraction system are disclosed. Water is removed from the water vapor laden exhaust of a gas turbine electrical generator by first increasing the concentration of water vapor in that exhaust stream while passing it through a desiccant means to regenerate the desiccant and remove water from the desiccant. The exhaust stream exits the desiccant at a lower temperature and higher vapor content level, and is then passed through one or more heat exchangers to further lower the temperature of the exhaust stream and condense water vapor out of the stream. The condensed water from the heat exchanger is collected and used for other purposes. The turbine exhaust leaving the heat exchanger is then passed through the adsorption region of the desiccant device to transfer water vapor remaining therein to the desiccant to dry the exhaust air stream before exhausting it to the atmosphere.
