Abstract

The invention relates to a method for controlling the adjustment angle phi of lamellae or flaps of an air guide device of a decentralised apparatus or installation for heating air, cooling air or ventilation, which has a fan, in particular according to the difference between room temperature TR and blow-out temperature TZ, the speed n being taken for a fan motor which is variable in its speed and the adjustment angle phi being controlled in accordance with this speed n alone or in addition with respect to the temperature difference and/or other measured quantities.

Description

Die Erfindung betrifft ein Verfahren zum Steuern des Stellwinkels von Lamellen oder Klappen einer Luftleiteinrichtung eines einen Lüfter aufweisenden dezentralen Luftheiz-, Luftkühl- oder Belüftungsgerätes oder -anlage, insbesondere nach der Differenz zwischen Raumtemperatur und Ausblastemperatur.The invention relates to a method for controlling the Setting angle of slats or flaps one Air guiding device of a fan decentralized air heating, air cooling or ventilation device or plant, especially according to the difference between Room temperature and blow-out temperature.

Es ist bekannt, den Winkel von Klappen oder Lamellen eines Luftheizgerätes nach der Differenz zwischen Raumtemperatur und Ausblastemperatur zu regeln. Die Funktion dieser Regeleinrichtung ist ausreichend bei gleichbleibender Ausblasgeschwindigkeit bzw. unveränderlicher Lüfterdrehzahl. Wird aber die Drehzahl verändert, ändern sich die Volumenströme und damit auch die Ausblasgeschwindigkeit und die Eindringtiefe des Luftstrahls und die Regelvorrichtung stellt sich nicht mehr auf die unterschiedlichen Strömungsbedingungen innerhalb des Raumes ein. Es kommt zu unerwünschten Temperaturschichtungen und Zugerscheinungen.It is known the angle of flaps or lamellae Air heater according to the difference between room temperature and regulate blow-out temperature. The function of this Control device is sufficient with the same Blow-out speed or unchangeable Fan speed. But if the speed is changed, change it the volume flows and thus also the Blow out speed and depth of penetration of the Air jet and the control device no longer turns to the different flow conditions within of the room. There are unwanted ones Temperature stratification and drafts.

Aufgabe der Erfindung ist es, eine Vorrichtung der eingangs genannten Art so zu verbessern, daß die gewünschten Luftdurchmischungen und Behaglichkeitskriterien auch bei unterschiedlichen Ausblasgeschwindigkeiten beibehalten bleiben.The object of the invention is a device of the beginning to improve the type mentioned so that the desired  Air mixing and comfort criteria also with maintain different blowing speeds stay.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß für einen in seiner Drehzahl veränderlichen Lüftermotor die Drehzahl und/oder der Druck bzw. die Druckdifferenz erfaßt und entsprechend dieser Eingangssignale allein oder zusätzlich zur Temperaturdifferenz und/oder anderen Meßgrößen der Stellwinkel gesteuert wird.This object is achieved in that for a fan motor with variable speed Speed and / or the pressure or the pressure difference detected and according to these input signals alone or in addition to the temperature difference and / or others Measured variables of the control angle is controlled.

Damit kann die Vorrichtung auf die verschiedenen Ausblasgeschwindigkeiten eingehen, d.h. die Klappen bzw. Lamellen werden so verstellt, daß auch bei veränderter Ausblasgeschwindigkeit eine optimale Luftbewegung innerhalb des Raumes erzeugt wird. So können z.B. bei einer geringeren Ausblasgeschwindigkeit die Klappen oder Lamellen so gestellt werden, daß der Luftstrom steiler in den Raum gelangt und die gleiche Eindringtiefe erreicht wird, wie bei der höheren Ausblasgeschwindigkeit. Unabhängig davon, ob die Drehzahl des Lüfters stufenlos oder in Stufen verändert wird, stets wird die Luft so in den Raum geführt, daß die Behaglichkeits- und Energieeinsparungskriterien beibehalten werden, d.h. es entsteht weder Zug noch entstehen erhebliche Temperaturdifferenzen.So that the device can be used on the different Blow out speeds, i.e. the flaps or Slats are adjusted so that even when changed Blow out speed an optimal air movement within of the room is generated. For example, at a lower blowing speed the flaps or lamellas be placed so that the airflow into the room is steeper arrives and the same depth of penetration is reached as at the higher blowing speed. Independently of, whether the speed of the fan is infinitely variable or in stages is changed, the air is always led into the room that the comfort and energy saving criteria be maintained, i.e. there is neither train nor considerable temperature differences arise.

Ein Ausführungsbeispiel der Erfindung ist in der Abbildung dargestellt und wird im folgenden näher beschrieben. Es zeigenAn embodiment of the invention is in the figure shown and is described in more detail below. Show it

Fig. 1 ein erstes Ausführungsbeispiel und Fig. 1 shows a first embodiment and

Fig. 2 ein zweites Ausführungsbeispiel. Fig. 2 shows a second embodiment.

Das Gerät 1 zum Heizen, Kühlen und/oder Lüften eines Raumes weist einen Axiallüfter 2 auf, der von einem Elektromotor 3 angetrieben wird. Im Ausführungsbeispiel ist das Gerät 1 so unterhalb der Decke eines Raumes oder einer Halle montiert, daß der Lüfter 2 senkrecht nach unten bläst.The device 1 for heating, cooling and / or ventilating a room has an axial fan 2 which is driven by an electric motor 3 . In the exemplary embodiment, the device 1 is mounted below the ceiling of a room or hall so that the fan 2 blows vertically downwards.

Unterhalb des Lüfters 2 befindet sich ein Heizregister 4 zur Erwärmung der durchströmenden Luft. Alternativ oder zusätzlich kann aber auch ein Kühlregister dort angeordnet sein. Unterhalb des Registers 4 sind in diesem Ausführungsbeispiel mehrere die Luftströmung lenkende Klappen oder Lamellen 5 parallel zueinander und um jeweils eine Längsachse drehverstellbar befestigt. Die Lamellen 5 sind durch ein Gestänge drehverstellbar, das durch einen Stellmotor 6 angetrieben wird. Die Art der Anordnung der Lamellen und des Gestänges ist aus den Deutschen Offenlegungsschriften 36 38 614 und 36 38 616 bekannt. Es wird auf diese Konstruktionen Bezug genommen. Der Motor 6, der die Lamellen 5 verstellt, wird durch ein Regelteil 7 gesteuert, an das der Motor 6 elektrisch angeschlossen ist. Durch eine elektrische Vorrichtung 8 ist die Drehzahl des Motors veränderbar. Die Drehzahl wird insbesondere durch einen manuellen Schalter oder ein anderes übliches Stellorgan 9 vorgegeben. In das Regelteil 7 geht sowohl die durch einen geeigneten Sensor 10 gemessene oder durch die Vorrichtung 8 vorgegebene Solldrehzahl 11 des Motors 3 als auch die über die Meßgeräte 12, 13 erfaßte Raumtemperatur und Ausblastemperatur ein. Im Regelteil 7 ist für jede Drehzahl des Motors 3 eine Kennlinie vorgesehen, die von übrigen Kennlinien unterschiedlich ist, so daß nicht nur entsprechend der Raumtemperatur, sondern auch entsprechend der Drehzahl des Motors 3 die Lamellen 5 verstellbar sind. Gleichgültig, ob die Drehzahl in Stufen oder stufenlos verändert wird, stets wird durch diese Veränderung entsprechend einer Kennlinie, insbesondere einer Kennlinienschar oder eines Kennlinienbereichs, die Stellung der Lamellen 5 verändert, um die vorgegebenen Behaglichkeitskriterien unabhängig von der Drehzahl zu erfüllen.Below the fan 2 there is a heating register 4 for heating the air flowing through. Alternatively or additionally, a cooling register can also be arranged there. In this exemplary embodiment, below the register 4 , 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 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 . In the control section 7 , a characteristic curve is provided for each speed of the motor 3 , which is different from 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 changes the position of the slats 5 in accordance with a characteristic curve, in particular a family of characteristic curves or a range of characteristic curves, in order to meet the specified comfort criteria independently of the speed.

Ein modifiziertes Ausführungsbeispiel ist in Abbildung 2 dargestellt, statt der Vorrichtungen zur Drehzahlerfassung ist hier die Erfassung des Drucks bzw. einer Druckdifferenz durch ein zwischen Heizregister 4 und Klappen oder Lamellen 5 angeordneten Drucksensor 14 dargestellt. Diese Anordnung ermöglicht es ebenfalls, Änderungen der Ausblasgeschwindigkeit bei sich ändernden Drehzahlen des Lüftermotors 3 durch eine Regeleinheit 7 zu berücksichtigen und die Klappen oder Lamellen 5 entsprechend einer in der Regeleinheit hinterlegten Kennlinie zu verstellen. Hinzu kommt, daß jetzt gleichzeitig auch sich ändernde Ausblasgeschwindigkeiten z.B. infolge allmählicher Verschmutzung des Registers 4 oder eventuell noch vorhandener Luftfilter zu einem reduzierten, vom Drucksensor 14 erfaßten Druck führen. Desgleichen beeinflussen varriierende Druckverluste in vorgeschalteten Luftführungeinrichtungen, wie z.B. Mischlufteinrichtungen, die geförderte Luftmenge und damit die Ausblasgeschwindigkeit. Derartige Einflußgrößen werden somit automatisch bei der Steuerung der Klappen und Lamellen 5 durch das Regelteil 7 berücksichtigt, indem bei geringerem Druck ein steilerer Klappenwinkel eingestellt wird und der Luftstrahl steiler nach unten zum Hallen- oder Raumboden gelenkt wird.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. In addition, changing blow-out speeds, for example as a result of gradual contamination of register 4 or possibly still existing air filters, now lead to a reduced pressure detected by pressure sensor 14 . Varying pressure losses in upstream air routing devices, such as mixed air devices, also influence the amount of air delivered and thus the blow-out 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.
