Abstract: The present invention provides an induction unit having a primary air inlet area, a return air inlet area, and an outlet area. A baffle separates the housing of the induction unit into first and second air flow paths. A source of primary air is attached in fluid communication with the air inlet area and a bank of nozzles is positioned within the first air flow path and in fluid communication with the air inlet area. A return air vent is positioned in fluid communication with the return air inlet area. Heat exchange tubes are positioned adjacent the return air vent and within the return inlet area of the housing, and at least one fan is mounted within the housing and in the second air flow path, wherein the fan will accelerate return air passing over the heat exchange tubes, through the second air flow path, and out of the air exit vent.

Abstract: The present invention is directed to a 360 degree ventilation system with a single unitary plenum. The present invention is also directed to a 360 degree ventilation system with a single mixing chamber extending at least substantially entirely around the perimeter of the blow ventilation system. The present invention is also directed to a 360 degree ventilation system with a heating/cooling units that extend substantially all the way around the perimeter of the ventilation system. The present invention is also directed to a 360 degree ventilation system with a single return air chamber.

Abstract: The present invention provides an air handling system that receives air from a primary air source and distributes that air in a room defining an enclosed space. The system is mounted in the ceiling of the room and generally comprises first, second, third, and fourth inductor units interconnected downstream to the primary air supply and which define first, second, third, and fourth areas, respectively, wherein the induced air flows through each of the inductor units, through a series of converging nozzles, and into each units first, second, third, and fourth areas, respectively, and an air diffusing mechanism positioned adjacent to the first, second, third, and fourth areas which directs the induced air in first, second, third, and fourth directions, respectively. The inductors are generally arranged in a square configuration with the diffuser extending in the square space bound thereby.
