Sound attenuation layers extend along at least a portion of the interior surface of the corresponding chambers. The sound attenuation layers are positioned between at least some of the adjacent chambers.

Abstract: A fan array is provided having a frame including a plurality of frame members. The frame members are joined to define a plurality of chambers. Each of a plurality of fan units is configured to be positioned in one of the plurality of chambers. Each fan unit has a motor. A plurality of local motor controllers are joined to corresponding motors. The local motor controllers are configured to control an operation of the corresponding fan unit. A master controller is configured to communicate with the local motor controllers. The master controller is configured to provide the local motor controllers with target operating parameters for the corresponding fan units.

Abstract: A fan array fan section in an air-handling system includes a plurality of fan units arranged in a fan array and positioned within an air-handling compartment. One preferred embodiment may include an array controller programmed to operate the plurality of fan units at peak efficiency. The plurality of fan units may be arranged in a true array configuration, a spaced pattern array configuration, a checker board array configuration, rows slightly offset array configuration, columns slightly offset array configuration, or a staggered array configuration.

Abstract: A modular air-handling plenum for capable of supporting surgical apparatus or other objects is disclosed. The plenum is usually rectangular, may be formed of sheet metal, and features a truss spanning the width of the plenum to carry the weight of the apparatus. The plenum itself is attached to the ceiling of a room. An air handling component may be included to provide filtered and/or conditioned air in the vicinity of the suspended apparatus, or the plenum may be used strictly as an apparatus support, with no air-conditioning function. An ordinary suspended ceiling may also be mounted in the plenum for continuity with the remainder of the room.

Abstract: A fan array fan section in an air-handling system includes a plurality of fan units arranged in a fan array and positioned within an air-handling compartment. One preferred embodiment may include an array controller programmed to operate the plurality of fan units at peak efficiency by computing the power consumed in various configurations and selecting the configuration requiring minimum power to operate.

Abstract: A system and method for controlling noise produced by an air handling system, for example, is provided. The system includes a source microphone to collect sound measurements from the air handling system and a processor to define a cancellation signal that at least partially cancels out the sound measurements. The system also includes a speaker to generate the cancellation signal. The sound measurements are at least partially canceled out within a region of cancellation. Accordingly, the system further includes a response microphone to collect response sound measurements at the region of cancellation. The processor tunes the cancellation signal based on the response sound measurements.

Abstract: An air filter assembly is configured to deliver filtered air to a room. The assembly may include a main housing having at least first and second surfaces, wherein the first surface differs from the second surface, one or more first air filters proximate to the first surface, wherein the one or more first air filters is configured to discharge a first portion of filtered air through the first surface in a direct direction, and one or more second air filters proximate to the second surface. The one or more second air filters is configured to discharge a second portion of filtered air through the second surface in a second direction that differs from the first direction.

Abstract: An illuminating airflow panel assembly is configured to provide illumination and allow air to flow therethrough. The illuminating airflow panel assembly may include a mounting bracket configured to secure the illuminating airflow panel assembly to a structure, and a main body connected to the mounting bracket. The main body may include opposed first and second planar surfaces and an outer peripheral edge. The main body may also include a plurality of airflow passages that extend from the first planar surface to the second planar surface. The airflow passages are configured to allow air to pass therethrough toward a target site. An illuminating member may be positioned around the outer peripheral edge of the main body. The illuminating member is configured to direct light toward the target site.

Abstract: An overhead support system is configured to be positioned within a room. The system may include a main housing that includes at least a portion of an air-delivery sub-system, a plurality of lighting elements secured to the main housing, a light control unit in communication with each of the plurality of lighting elements, and a light operation interface in communication with the light control unit.
