An air delivery assembly having a baffle and an ionizer. The baffle is constructed to affect air flow such that air flowing through the air delivery assembly has an air velocity and a direct flow to the ionizer that is effective to deliver ions through a diffuser of the air delivery assembly and up into a room. The air delivery assembly may be included with a damper and/or an upper diffuser to form an air terminal, which may be used in a raised floor air distribution system.

An elongate air delivery assembly having a housing extending between two end caps. The housing includes a plurality of exit vents from which airflow is provided in a consistent sheet at a uniform velocity, and the housing is rotatable about a central longitudinal axis to change a direction of the airflow. A method of improving plant cultivation includes positioning one or more elongate air delivery systems adjacent rows of plants such that the sheet of air generated by the elongate air delivery system is directed horizontally across the plants underneath their plant canopy.

A mechanism for opening and closing a damper valve of a diffuser mechanism is provided. Embodiments of the invention include a damper construction that selectively alters the amount of air flow through a diffuser grille using a three-plate damper valve. The three-plate damper valve includes a manual plate, a fixed plate, and a motorized plate. The manual plate is manually rotatable around a central axis, while the motorized plate is mechanically rotatable about the same axis. The motorized plate is mechanically and/or remotely controlled using a stepper motor coupled to the motorized plate. Further, the diffuser mechanism includes a sensor for determining the location of the motorized plate with respect to a starting position. As such, multiple configurations of the manual plate and the motorized plate may be used to alter the air flow through the resulting channels of the damper mechanism.

A damper having a housing includes a rotatable damper vane therein constructed to minimize the passage of air between the vane and the housing when the vane is in a closed position. The housing includes a pair of opposed walls having a channel or flute therein adjacent outer edges of the vane when the vane is in the closed position. The outer edges of the vane terminate in domed or arcuate shaped surfaces that generally correspond with the channel. The arcuate shaped surfaces are a distance apart that is greater than a distance between the opposed walls such that the arcuate shaped surfaces are received in the channels when the vane is in the closed position. The housing also includes a pair of opposed sidewalls having a ridge therein at a location that aligns with an edge of the vane when the vane is in the closed position.

Variable volume floor diffuser with attachment means
A diffuser for positioning in an opening of a passageway having conditioned air, the diffuser including a grate assembly, a pan assembly, and a retention assembly. The grate assembly includes an upper portion and a lower portion. The upper portion contains an aperture, a plurality of slotted sections, and a flange. The lower portion includes downwardly depending sidewalls and a stop. The pan assembly includes a tray with an aperture and a plurality of upwardly depending legs. The retention assembly couples the grate assembly with the pan assembly and contains a first member that is movable from a first position to a second position for selectively engaging the stop.
A floor terminal for positioning in a passageway in a raised floor system having conditioned air. The floor terminal includes an air delivery system, a damper coupled to the air delivery system, and a grate assembly coupled to the air delivery system. The air delivery system includes a pair of sidewalls, a back, a bottom, a bracket and a baffle, wherein the baffle is selectively coupled between the pair of sidewalls. The damper is selectively coupled to the air delivery system. The damper includes a vane positioned between a frame and a motor in a housing, wherein the motor moves the vane between a first position and a second position to selectively vary the flow of air through the damper. The grate assembly fits within the bracket to couple the grate assembly with the air delivery system to mount the air delivery system and the damper within the passageway and to position the air delivery system within the hole in the floor.
