| 20110121087 | UNDER-FLOOR TROUGH WITH HEATING ELEMENT - An under-floor trough is provided for use with a raised-floor system. The under-floor trough includes an air-delivery assembly, one or more plurality of dampers, a support system, and a heating element. A control unit, removable from above the raised-floor system, and a baffle are disposed within the air-delivery assembly. The dampers include vanes that are actuated between open and closed positions according to a time modulated duty cycle to control the flow of conditioned air to a room. The support system provides a plurality of legs disposed between the bottom of the air-delivery assembly and a sub-floor. A bracket is mounted to a wall and the under-floor trough is supported thereby. The heating element is disposed within the air-delivery assembly. Conditioned air is provided to a room at high flow rates for short durations based on the duty cycle, thereby increasing the uniformity of cooling provided to the room. | 05-26-2011 |
