An air conditioning system in a building space having side walls and a hollow horizontal partition or wall which provides a generally unobstructed chamber or plenum for preconditioned air at or close to atmospheric pressure, a hollow column extending from the horizontal partition at a selected location 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.

In the method of air conditioning a room space, the steps which comprise; providing a horizontally generally unobstructed plenum chamber vertically contiguous to and horizontally generally coextensive with the room space without duct work between the plenum chamber and room space, supplying substantially all necessary conditioned air to the plenum chamber at a pressure above atmospheric just sufficiently to overcome gravity and friction and fill the plenum chamber, selectively locating a vertical passageway in said room space and communicating at one end directly with the adjacent portion of said plenum chamber, the conditioned air being supplied to the plenum at not more than 0.1 inch of water which is insufficient pressure to move a selected rate of conditioned air through said passageway during air conditioning operation, and applying air moving force in said passageway for moving said substantially all necessary conditioned air at a selected rate from said plenum chamber through said passageway to the selected location in said room space for both cooling of a person proximate to the passageway and general cooling throughout the room.
