Definitions

  • the invention relates to a method for controlling the setting angle of lamellae or flaps of an air guiding device of a decentralized air heating, air cooling or ventilation device or system having a fan, in particular according to the difference between room temperature and blow-out temperature.
  • the object of the invention is to improve a device of the type mentioned so that the desired Air mixing and comfort criteria are maintained even at different blowing speeds.
  • This object is achieved in that the speed and / or the pressure or the pressure difference is detected for a variable-speed fan motor and is controlled in accordance with these input signals alone or in addition to the temperature difference and / or other measured variables of the actuating angle.
  • the device to respond to the different blowing speeds, i.e. the flaps or lamellae are adjusted in such a way that optimal air movement within the room is generated even when the blow-out speed changes. For example, at a lower blowout speed, the flaps or louvres are set so that the airflow enters the room more steeply and the same depth of penetration is achieved as at the higher blowout speed. Regardless of whether the fan speed is changed continuously or in steps, the air is always led into the room in such a way that the comfort and energy saving criteria are maintained, i.e. there is neither draft nor significant temperature differences.
  • the device 1 for heating, cooling and / or ventilating a room has an axial fan 2 which is driven by an electric motor 3.
  • the device 1 is mounted below the ceiling of a room or hall so that the fan 2 blows vertically downwards.
  • a heating register 4 for heating the air flowing through.
  • a cooling register can also be arranged there.
  • a plurality of flaps or lamellae 5 guiding the air flow are fastened parallel to one another and adjustable in rotation about a longitudinal axis in each case.
  • the slats 5 are rotatably adjustable by means of a linkage which is driven by a servomotor 6.
  • the type of arrangement of the slats and the linkage is known from German Offenlegungsschriften 36 38 614 and 36 38 616. Reference is made to these constructions.
  • the motor 6, which adjusts the slats 5, is controlled by a control part 7, to which the motor 6 is electrically connected.
  • the speed of the motor can be changed by an electrical device 8.
  • the speed is specified in particular by a manual switch or another conventional actuator 9.
  • the control part 7 includes both the target speed 11 of the motor 3, measured by a suitable sensor 10 or specified by the device 8, and the room temperature and blow-out temperature detected by the measuring devices 12, 13.
  • a characteristic curve is provided for each speed of the motor 3, which is different from the other characteristic curves, so that the fins 5 are adjustable not only according to the room temperature, but also according to the speed of the motor 3. Regardless of whether the speed is changed in steps or continuously, this change always corresponds to a characteristic curve, in particular one Characteristic family of curves or a range of characteristic curves, the position of the slats 5 changes in order to meet the specified comfort criteria regardless of the speed.
  • FIG. 2 A modified exemplary embodiment is shown in FIG. 2, instead of the devices for speed detection, the pressure or a pressure difference is shown here by a pressure sensor 14 arranged between the heating register 4 and flaps or fins 5.
  • This arrangement also makes it possible to take changes in the blow-out speed into account with changing speeds of the fan motor 3 by means of a control unit 7 and to adjust the flaps or fins 5 in accordance with a characteristic curve stored in the control unit.
  • changing blowing speeds are now also possible, e.g. due to gradual contamination of the register 4 or possibly still existing air filter lead to a reduced pressure detected by the pressure sensor 14.
  • Varying pressure losses in upstream air routing devices e.g. Mixed air devices, the amount of air conveyed and thus the blowing speed.
  • Such influencing variables are thus automatically taken into account in the control of the flaps and lamellae 5 by the control part 7, in that a steeper flap angle is set at a lower pressure and the air jet is steered downwards to the hall or room floor.
