Definitions

  • the invention relates to an air outlet, in particular Slot outlet or swirl outlet, with a housing, the at least one with an air outlet opening provided air baffle preferably adjustable records.
  • Such air outlets are at the end of a frequently long Path of an air treatment; they are ultimately for direction and momentum of the air flow in one Space or the like.
  • air outlets with cover panels provided to optically in wall or ceiling openings to be able to install properly.
  • Operational such air outlets have been found that very often on the wall or ceiling and also on Air outlet itself (especially on the end panels) Soiling occurs. This Soiling is mostly limited by sharp Streaks of dirt formed by those entrained Indoor air.
  • the one coming out of the air outlet Airflow leads to a lateral inflow of indoor air, with the particles contained therein (for example tobacco smoke) on the ceiling or wall directly in the area of the air outlet or on Store the air outlet yourself.
  • This induced space airflow flows laterally towards the air outlet and is in the immediate vicinity of the air outlet opening then from that emerging from the air outlet opening prepared and therefore clean supply air flow entrained. Forming from the air outlet opening after prolonged operation mostly in a pollution area from about 8 to 15 cm Streaks of dirt.
  • An air outlet emerges from DE-B-2 804 670, whose housing is rotationally symmetrical is. Inside the case is a relocatable Valve body arranged. Located in the area of the estuary a relocatable nozzle plate. Depending on Position of the nozzle plate and the valve body is a radial and / or a vertical air outlet possible in the room to be ventilated.
  • the invention is therefore based on the object to create an air outlet that said Avoids contamination.
  • the sealing air flow according to the invention forms one air curtains consisting of primary air supplied, because of its contact with the housing itself (especially on the installation opening cover) or the adjacent built-in wall or ceiling area and thereby preventing sideways, especially by induction inflowing with dirt particles provided room air in contact with the air curtain covered areas comes up, so none Pollution can occur.
  • the sealing air flow thus forms a wedge of separation air in the side Area next to the air outlet opening of the air outlet. If slot outlets are used, is a slit-shaped sealing air outlet opening on both sides of the emerging from the air outlet opening Main air flow is provided so that there is bilateral of the slot outlet and the adjacent one Wall or ceiling areas not the mentioned Can form streaks of dirt.
  • the air outlet referred to as the main air outlet opening in case of an Swirl outlet is the air outlet opening for the main air flow from an annular sealing air outlet opening surrounded so that around the swirl outlet around the sealing air flow emerges and the deposit of dirt and room air particles prevented. Result due to the mentioned air curtain optimal flow conditions, so that the use of the air outlet according to the invention brings an acoustic improvement.
  • the Air outlet opening and the sealing air outlet opening are assigned to each other in such a way that between the main air stream emerging from the air outlet opening and the barrier air flow a stable jet separation consists. This means that even when different large supply air flows always a separation between sealing air flow and main air flow, therefore no or only little intermingling, is present.
