Process and apparatus for controlling the flow of ventilating-tempering air in a room to cause the flow to remain primarily along the walls, ceiling and floor, thereby to achieve better distribution of incoming air and more uniform room temperatures without uncomfortable drafts in the main body of the room. To accomplish this, the ventilating-tempering air is initially launched into the room along a boundary surface such as a wall or ceiling, and nozzles below the ceiling form air screens or jets below the ventilating-tempering air stream to guide it along the ceiling and down the walls. An intermediate grate-like ceiling of crossed lamellae is also preferably used to aid in separating ventilating-tempering air stream from the main center of the room.
