Abstract: An air conditioning system comprises a room divider extending upwardly from a floor, the room divider having first and second sides for supplying conditioned air to an area. The room divider comprises a first panel integrally connected to a second panel to form the room divider. The first and second panels are spaced apart a predetermined distance to define an air flow area therebetween for allowing air to flow between the panels. The first and second panels include a bottom portion positioned proximate a first side of the floor, the bottom portion including a generally imperforate bottom member adjacent the second panel and sized to complement the air flow area such that air cannot flow directly through the bottom portion from or to the air flow area. At least one air outlet is integral with one of the first or second panels and is elevated a predetermined distance from the floor for allowing air within the air flow area to flow therethrough to an area surrounding the room divider.

Abstract: An air conditioning system in a building space having side walls and a hollow horizontal partition or wall which provides a plenum for preconditioned air at substantially atmospheric pressure, a hollow column extending from the horizontal partition for receiving conditioned air, air outlets in the column for distributing air to the immediate environs of the column, a fan in the column for moving air from the plenum into the column and through the air outlets, and a selectably variable fan control in the building space.
