Abstract: Various embodiments are described for humidifying an air stream in a duct are described. In one form the duct is part of a humidification system in a building such as a residence or commercial structure while in another form the duct is part of a standalone unit. The described embodiments use ultrasonic elements for generating a mist composed of droplets and fog and the fog is drawn or pushed by an air stream towards a duct. The duct utilizes a dispersal structure formed of one or a plurality of tubes with openings and distributed at least partly across the duct so that the air stream in the duct can entrain the fog and distribute this in manner whereby the fog can quickly dissipate and evaporate for humidification of the air stream.

Abstract: An air humidification system for the humidification of a zone includes supply ducts and return ducts extending from a first air handler. A second air handler has an enclosure sized to form a fog absorption region with a cross-sectional area that is greater than the cross-sectional area of the air conditioning ducting coupled to the zone. The enclosure has an intake and a discharge through which air passes. A compressor associated with the second air handler provides pressurized air for the generation of the fog for humidification. A fogger has a water input coupled to the pressurized water supply, an air input coupled to the pressurized air supply from the compressor, and a discharge port from which fog is produced. A humidification control is interposed between the supplies of pressurized air from the compressor and water to the fogger in the enclosure to produce fog from the fogger inside the second air handier when the humidification in the zone is below a desired set point.

Abstract: A system for humidifying an air stream comprising an array of fogger nozzles supplied with air and water by a grid of supply tubes, feedback means connected to the grid of air supply tubes and coupled to the pressure regulating means for the air and water supply tubes, for establishing a predetermined pressure differential between the grids of air and water supply tubes.

Abstract: A fogging system and fogger bar assembly are disclosed wherein a plurality of foggers are mounted on an array and operatively connected to air and primary water lines. A second water line is introduced in parallel with the primary water lines to provide an equalization of pressure in the primary water lines and dampen vibrations from the foggers. Check valves are used near the foggers to reduce the feedback of undesirable shocks and noise from the foggers into the primary water lines. A system is described wherein a plurality of pressure regulators are used to supply the same pressure to primary water lines in a system where a plurality of fogger bar assemblies are used in a vertical orientation.

Abstract: A method and apparatus are described to evaporatively cool air leading to a gas turbine engine by injecting water fog into the inlet air in a controlled manner. A signal is generated representative of the capacity of the inlet air stream to absorb water vapor and used to regulate the amount of fog introduced into the inlet air stream.
