An air containment system (22) is configured to span an aisle (12) formed by two rows of racks (14,16) or by one row of racks (14) and a wall (56) to form a ceiling. The air containment system (22) includes a frame structure (24) configured to be supported by the two rows of racks (14,16) or by the one row of racks (14) and the wall (56). The air containment system (22) further includes at least one ceiling panel (30) releasably supported by the frame structure (24), and a lock assembly (64) coupled to the frame structure (24) and configured to release the at least one ceiling panel (30) upon detecting a predetermined condition. Embodiments of the air containment system (22) and methods for releasing ceiling panels (30) are further disclosed.
摘要:
A dynamic responsive acoustic tuning envelope system that includes a movably connected set of cells, each possessing sound reflecting, sound absorbing, and/or electro-acoustic properties, and which are assembled according to the principles of rigid origami. So configured, the system is capable of both localized surficial deformation to alter the material surface exposure, transform its textural profile, and alter the enclosed volume of space in a single material envelope, thereby tuning the acoustics of the environment in which the system resides.
摘要:
The present invention is a ceiling-mountable enclosure comprising a support frame, a lightweight inner enclosure, and a back box configured for installation in a suspended ceiling. The apparatus of the present invention includes a removable device door configured to be mounted to the support frame. Electrical and signal wires are routed through conduit access plates provided at the back box. Electrical or other equipment is mounted to a removable device door. The removable device door with mounted equipment is attached to the support frame, then rotated upwards to fit flush with the ceiling and fastened to the support frame. A variety of power receptacles are provided that are configured to be mounted to either the back box, the inner enclosure, or the removable device door. The enclosure includes a cooling system comprising an electrically powered fan and air ducts integrated into the inner enclosure.
摘要:
Closable inspection opening (1) for dry construction, comprising a plate (3) which is provided with holes (2) and has an opening (4), and a cover (5) which is provided with holes (2) and is intended for covering the opening (4), wherein the plate (3) has an opening edge (6) bounding the opening (4), and the cover (5) has a cover edge (7). The inspection opening is characterized in that the holes (2) provided in the plate (3) and in the cover (5) are arranged in such a way that they are situated at a distance from the opening edge (6) and the cover edge (7).
摘要:
An overhead arrangement, for use in a suspended ceiling system having a grid framework of frame elements lying in a ceiling plane and bounding a plurality of openings for supporting a corresponding plurality of ceiling members, includes an electrical apparatus, such as a DC power supply, a support for supporting the electrical apparatus on the framework at an elevation above one of the ceiling members supported in one of the openings, and a slanted control panel on the housing and having manually accessible controls and visually accessible displays. The slanted control panel is obliquely and downwardly inclined relative to the ceiling plane to enable manual access to the controls and visual access to the displays through the opening to the slanted control panel from below the framework after the ceiling member is at least partially removed from its opening without mechanical interference between the ceiling tile and the electrical apparatus.
