Abstract: A bi-surfaced raised access floor panel is provided. The panel is constructed with a cross-braced framework. A generally square plate is rigidly connected to an upper surface of the framework. The plate has four corner formations and is bisected symmetrically to define first and second halves. The first halve is substantially configured as a solid load bearing surface which is adapted to support a data processing server. The second halve includes a plurality of clear perforations capable of circulating an air flow as an element of a cold aisle forming installation in a data center.

Abstract: A precast under floor air delivery construction is provided which includes a plurality of precast concrete system having an upper base floor surface and a lower surface, a plurality of floor panel support means bearing directly to the upper base floor surface capable of an under floor air delivery between the floor panels and the upper surface, a plurality of access floor panels connected to the support means, and a fire protection barrier applied between the concrete slabs.

Abstract: A wind inlet and outlet case for a blower of an air conditioning system is connected to an inner machine, including a body and a faceplate. The body is separated into a wind inlet room and a wind outlet room with a lengthwise vertical wall, and the wind inlet room and the wind outlet room are respectively connected with the inner machine with a separate guide pipe. The faceplate is combined with the body, having a wind outlet provided with a movable leaf unit to change direction of wind blown out, and with a wind inlet provided with a filter. Thus plural sets of the wind inlet and outlet cases may be connected to the inner machine, wind blown out and wind sucked back are guided separately by guide pipes to keep good quality of air, lowering cost, and facilitating maintenance and repair.

Abstract: The invention relates to an aerated flooring system for use in athletic arenas or gymnasiums. The flooring system includes a top layer that provides a surface for the activities to be conducted on the floor. The system also includes at least one ventilation device. The ventilation device covers an air flow shaft within the flooring system, helping to prevent debris from falling in the air flow shaft, but allowing air to flow through the ventilation device. The ventilation device allows air to ventilate out of the flooring system. A support layer below the top layer provides support to the flooring system. A ventilation layer below the flooring is sized to allow air movement through the layer. The air flow shafts allow air to travel from the ventilation layer to the ventilation device. A base is below the ventilation layer and provides support for the flooring system above. A blowing device is controlled by a computer system that monitors the system using sensors.

Abstract: A work station for supplying conditioned air and electrical conductors to the vicinity of a worker, for withdrawing return air from the space near the worker and for seating the worker and positioning his/her equipment. The work station includes a services distributor with vertically extending but separated passageways dedicated exclusively to supply air, return air and electrical wiring. A portion of the structure contains adjustable support arms for positioning equipment to be used by the workers; the seat is positioned adjacent the service distributor. Communication spaces are provided at spaced apart points whereby the services may leave or enter their vertically extending spaces and travel generally horizontally to those areas in which the services needed or are to be used. The apparatus preferably, but not necessarily, includes a task lighting that illuminates the area surrounding the worker and/or the equipment positioned by the support arms.
