Abstract: The invention concerns a ceiling air outlet, especially for air-conditioned areas, with a housing which can be connected to a supply air line and has a separating wall, two flow paths and an outlet grate, whereby an adjustment flap is located in at least one of the flow paths. In order to maintain a stable flow of areal air under a variable amount of supply air furnished by the air-conditioning system, the separating wall is positioned essentially parallel to the outlet grate and has at least one opening which can be closed by the adjustment flap. A series of jet openings or jet slits directed toward the outlet grate are located in the separating wall at least in the area of the free edge of the adjustment flap.

Abstract: An air conditioning system ceiling air outlet comprising a warm air duct for vertically downward direction of warm air, a cold air duct surrounding the warm air duct for outwardly directing cold air, the ducts terminating at their inlet ends in a common connecting stub, covering plates for the intake ends of each of the ducts and mounted in the connecting stub, the covering plates being mounted on a common axis of rotation and at an angle to each other so that when one of said ducts is closed by one of said plates, the other of said ducts is open.
