Definitions

  • the invention relates to a method for controlling the ventilation of rooms, wherein an air flow through an inlet into a duct system through which a plurality of air outlets, e.g. for a large room or a plurality of rooms to be supplied with air and is supplied to the rooms via air outlets and in the duct system is a plurality of volume control.
  • air conditioning systems which are supplied centrally by an air source with fresh air.
  • This fresh air is blown for example by a fan in a corresponding channel system and led from there to individual air outlets in the rooms. So that a control of the air flow can be made are Volume flow controller provided in the individual line.
  • the shows DE 197 10 404 C1 a method for adjusting an air duct system and in particular the amount of air flowing out of outlet devices of an air duct system.
  • an outlet device is adjusted so that a predetermined amount of air flows out of the outlet device, after which this setting is transmitted to the subsequent outlet devices.
  • This device has proved to be very useful for the regulation of airflow within a single room.
  • a system for controlling an air supply system for example, ceiling outlets with volume flow control is known, wherein in the air supply system operated by servo motors air flow control elements, such as butterfly valves, are arranged. In this case, several servo motors are to be connected to a central control unit.
  • the object of the present invention is to provide in a duct system over which a plurality of air outlets, e.g. for a large room or a plurality of rooms to be supplied with air, to improve the air flow and in particular to uniform.
  • At least part of the volume flow stabilizer or volume flow regulator is locked after a regulation.
  • volumetric flow regulators preferably as many as rooms to be supplied with air, in the duct system built-in.
  • the volume flow stabilizers or volume flow controllers can be controlled mechanically, electrically or pneumatically. For example, they can also regulate themselves automatically.
  • the regulation of the volumetric flow controller or volumetric flow stabilizer on the one hand is there to promote a certain volume of air through a particular channel strand. That means, the volumetric flow controllers or volumetric flow regulators regulate the air flow. Irregularities in the individual branch lines are compensated by different positions of the volume flow stabilizer or volume flow regulator and in particular the air flow control valves. With this adjustment, the flaps in each volume flow stabilizer or volumetric flow controller assume a specific position for a specific air flow.
  • the locked flap wings ensure that all rooms are evenly ventilated. Without this lock, the volumetric flow regulator would attempt to operate in a controlled manner, meaning that it opens much wider in the lower air. This would some volume flow stabilizer or volume flow controller, the are favorable in terms of flow, promote the full volume of air, while other flow regulators or flow regulators, which are unfavorable in terms of flow, are also fully open, but can not be supplied with sufficient air. This means that the individual rooms are supplied with different air. This is prevented by the present invention.
  • the damper blade position of the individual volume flow stabilizers can vary in a system, due to the pressure conditions, air volumes and duct sizes.
  • a channel system which consists of a main line 2 and five branching branch lines 5.1 to 5.5.
  • This duct system is connected via an inlet 3, in which a volume flow stabilizer or volumetric flow controller is located, with an air conveyor system, not shown in detail, through which air can be introduced into the duct system 1.
  • This air conveyor system may be, for example, a fan.
  • each branch line 5.1 to 5.5 is also again a volume flow stabilizer or volume flow controller 4.1 to 4.5, via which the current flowing through the respective branch line 5.1 to 5.5 air flow can be regulated.
  • a volume flow stabilizer or volumetric flow controller is for example from the EP 0 539 817 A2 known. He usually has a flap with which a cross section of the air duct tube can be reduced or increased, so that more or less air flows through this tube. The flap is then usually associated with a control device with which the position of the flap can be adjusted.
  • control devices for the volume flow of air are commercially available, which is why a further description is omitted.
  • Each branch line 5.1 to 5.5 ends in an air outlet 4.1 to 4.5, from which the air can then flow out into a space not shown in detail.
  • the control valve is pivoted under the action of the fluid flowing against the control valve against a restoring force from an open position to a closed position and swung back at decreasing flow of the flowing medium by the restoring force back into the open position.
  • the pivot position of the control valve so that the volume flow is automatically controlled in the air tube.
  • the same is also done by an electric or pneumatic drive.
  • the problem lies in the fact that the individual branch lines 5.1 to 5.5 with their air outlets 6.1 to 6.5 and the corresponding volume flow stabilizer or volume flow controllers 4.1 to 4.5 are relatively far apart, so that the corresponding flaps are exposed to a different strong air flow.
  • volumetric flow controllers 4.2, 4.3 and 4.4 allow so much air to pass through that there is no air left for the volumetric flow controllers 4,1 and 4,5, and these rooms will ultimately be at night setback do not flush with fresh air. Electric or pneumatic volumetric flow controllers can then be readjusted so that the regulators 4.2, 4.3, 4.4 continue to close the damper blade in order to ensure that sufficient air remains for 4.1 and 4.5.
  • volume flow stabilizers or volumetric flow controllers 4.3, 4.4 and 4.2 close more than the volume flow stabilizers or volumetric flow controllers 4.5 and 5.1, so that more air flows out of the corresponding air outlets 6.3, 6.4 and 6.2 as from the air outlets 6.5 and 6.1.
  • the volume flow regulator or volumetric flow controller and here in particular the corresponding flap is locked, so that with reduced air flow from each air outlet 6.1 to 6.5 the same amount of air flows out into the corresponding space.
