Definitions

  • the invention relates to a system for regulating an air supply system, for example ceiling outlets with volume flow control, air flow control elements such as butterfly valves, slats or the like being arranged in the air supply system by means of servomotors or the like.
  • Air supply systems are known in many forms. In the present case, reference is made in particular to those air supply systems in which volume flow control takes place.
  • such plant parts are shown in P 39 17 360.7.
  • DE-PS 33 36 911 a volume flow control by means of a measuring cross is shown.
  • butterfly valves are usually actuated by means of a servomotor.
  • the actuation is usually carried out by an electric motor, but other actuators are also intended to be encompassed by the present inventive concept.
  • the present invention should not be limited to the butterfly valves and lamellae mentioned.
  • the object of the present invention is to develop a system of the type mentioned above, which is easy to install and operate. It is also intended to save energy.
  • Adjustment devices are preferably also connected between the control device and the servomotor, a corresponding setting potentiometer being provided for each servomotor here, for example.
  • This potentiometer and the control unit should be switchable from 0-10 V.
  • up to 25 adjustment devices can be connected to one control device. This in turn means that up to 25 different switching options are possible within an air supply system for a building or a production hall. If more switching options for different temperature requirements are desired, only one additional control unit needs to be installed.
  • This control unit is preferably located in a control center, while the individual motors and air flow control elements are arranged in the rooms at desired locations.
  • a caretaker or plant supervisor only needs to set the desired new air volume for the adjustment device in question from the control center, the further control is taken over by the control device.
  • Both the potentiometer and the control unit are connected to an energy source, possibly via a transformer. Then only one main line between the energy source and the control potentiometer is necessary, and furthermore only one control line per control potentiometer. As a result, the wiring, switching, isolation and operation are extremely simplified in practice.
  • Appropriate temperature sensors should be connected to the control unit, which control the control unit or the control potentiometers via the control unit. There is also the possibility of assigning a time switch to the control device, by means of which the control device is only switched on in certain time periods.
  • the system according to the invention can be used for all outlets on the market where air volume control takes place. These can be ceiling outlets, volume flow controllers or the like. With the use of the system, it is possible to create a well-functioning ventilation and air-conditioning system in which a lot of energy can be saved. This happens in particular through the quick response of the adjustment devices and thus the control of the servomotors.
  • the desired air volume and temperature can be precisely supplied with these devices via the peripheral zone. The same applies to outlets.
  • FIG. 1 In the present exemplary embodiment according to FIG. 1, three pipe sections 1, 1a and 1b of an air supply system are shown, in which there are, as an example, a measuring cross 2 and a flap (not shown) for volume flow control. Corresponding signal boxes 3 or servomotors are provided on the outside of the pipe sections 1.
  • a control potentiometer 4 is assigned to each servomotor 3, by means of which the motor 3 is regulated. These potentiometers 4 represent adjustment devices. They can be switched from 0-10 V.
  • Both the control motors 3 and the control potentiometer 4 are connected via a main line 5 to a control device 6, the structure of which is described below.
  • the control unit 6 is also assigned a timer 7, a room temperature sensor 8 and a transformer 9.
  • the incoming alternating current is transformed from 220 V to 24 V via this transformer 9, with the transformer 9 also being assigned a corresponding fuse 10 in accordance with the information provided by the transformer manufacturer.
  • the system can be switched on via a switch 11 (see FIG. 2).
  • the timer 7 then takes over a desired commissioning of the system at predetermined times.
  • the transformer 9 is connected, on the one hand, directly to the control unit and, on the other hand, via the two lines 12 and 13, which together form the main line 5, to each control potentiometer 4.
  • These potentiometers 4 receive their corresponding energy through these lines 12 and 13.
  • the control unit itself can also be switched from 0-10 V. It has a control line 14 or 15 to the individual setting potentiometers 4a or 4b. In the present case, only two such control lines 14 and 15 are shown, with only two control potentiometers 4a and 4b being provided for the corresponding control motors 3a and 3b. It is contemplated that up to 25 control potentiometers 4 can be switched on each control unit. This enables the potentiometer 4 to be actuated very quickly.
  • the adaptation to the desired temperatures is also carried out in accordance with the room temperature sensor 8, and several of these sensors could also be provided here.
