Abstract: A system for a room with a ceiling is provided. Air supply equipment forms a laminar flow of clean air around a target by supplying the clean air downward from an outlet provided in a first area of the ceiling located directly above the target. Operating light equipment illuminates a working area on the target in a shadowless manner by multiple light sources provided in a second area around the first area. Surface light emitting equipment controls a surface light emitting member provided in a third area around the second area.

Abstract: A climate control system includes a fluid delivery module. The fluid delivery module includes a housing defining a fluid flow path between an inlet and an outlet with the outlet having an elongated, slit-like shape and is not visible within a sight line of a user. The fluid delivery module further includes a fluidic control device disposed within the housing between the inlet and the outlet and movable to vary a direction of the fluid flow path within the housing.

Abstract: A ceiling mounted ventilation fan comprises a main housing including a first opening communicating with a duct and a second opening communicating with inside of a room, and a fan unit including a fan casing having an air inlet opened in the main housing, and the fan casing includes a first engagement part releasably engaged with the first opening of the main housing, and a second engagement part releasably engaged with an inner wall of the main housing, positioning of the fan casing in an installation position is achieved in a state that the first engagement part is engaged with the first opening and the second engagement part is engaged with the inner wall of the main housing, and a state of the engagement can visually be confirmed through the second opening in a state that the positioning is achieved.

Abstract: An air vent is provided having a housing, an air inlet opening located in the axial direction with respect to the housing and an air discharge opening opposite the air inlet opening, an air-conveying element located in the housing having a first air-conveying surface and a second air-conveying surface, which is opposite the first air-conveying surface, wherein a first air channel is formed by the housing and the first air-conveying surface and a second air channel is formed by the housing and the second air-conveying surface, wherein the first air channel is configured to transport to the air discharge opening a first volume flow of air that can flow into the housing through the air inlet opening, wherein the second air channel is configured to transport to the air discharge opening a second volume flow of air that can flow into the housing through the air inlet opening, and a first wing, wherein the first wing is arranged movably on the end of the air-conveying element facing the air inlet opening, wherein t

Abstract: The invention relates to an air vent comprising a housing, an air inlet opening, which is located in the axial direction of the housing, and an air outlet opening, which is disposed opposite the air inlet opening, a first air guide surface, which has a first bulge and is disposed in the housing, and a second air guide surface, which has a second bulge and is disposed in the housing, wherein the first bulge points in a first direction and the second bulge points in a second direction, wherein the first direction and the second direction oppose one another and extend perpendicularly to the axial direction, wherein the first air guide surface and the second air guide surface are disposed at a distance from the housing, wherein a first air duct is formed by the housing and the first air guide surface, and wherein a second air duct is formed by the housing and the second air guide surface, wherein the first air duct is designed to convey a first volumetric flow of air—which can flow into the housing through the ai

Abstract: A boom assembly is configured to movably secure equipment to a ceiling or plenum extending from the ceiling. The assembly may include an arm sub-assembly secured to the ceiling, equipment secured to an end of the arm sub-assembly, and an air delivery member extending through the arm sub-assembly. The air delivery member may include a first end in communication with an air delivery chamber within the ceiling or plenum, and a second end in communication with air passages formed through the equipment. Airflow is directed from the air delivery chamber out through the air passages formed through the equipment towards a target location.

Abstract: A system for distributing air through an opening in a ceiling into a room, the ceiling being supported by spaced apart joists or other ceiling structural members, the air being supplied by a duct located above the ceiling, including a plenum having an open top connected to the duct and an open bottom in communication with the ceiling opening. A support bar extends through the plenum and secured at its opposed ends to ceiling structural member. A motor hanger is secured to the support bar. An air diffuser is positioned in communication with the plenum open bottom. A fan motor is supported to the lower end of the motor hanger. A plurality of generally horizontally extending fan blades are attached to and rotated by the motor. Air is passed from the duct through the plenum and diffuser into the room, distribution of the air being augmented by the fan blades as rotated by the motor.

Abstract: A ceiling structure within a cleanroom, including an array of cleanroom filters supported in openings of a grid support structure, wherein the ceiling structure includes a gel track coupled either at the top of the grid support channel. The cleanroom filters including a peripheral flange are suspended in the ceiling structure by having a ceiling edge of the peripheral flange either immersed in the gel track at the top of the grid support structure or using a cleanroom filter having gel or the lower knife edge seal thereof engaging a portion of the top of the grid support channel. Filtered air passes through the channel structure into the vortex region to reduce the vortex region or dead air space below the channel as well as prevent the accumulation of particulate material in the interior of the channel. A damper may be provided with the grid support structure to control the flow of filtered air into the interior of the grid support structure.
