Description

Die Erfindung betrifft eine Luftauslassvorrichtung zur Belüftung von Räumen mit einem an einen Zuluftkanal anschliessbaren Verteilkasten, mit einem von dem Verteilkasten zu dem Raum führenden Luftauslassrahmen, mit den Luftauslassrahmen in Längsrichtung unterteilenden Austrittsöffnungen, mit in Längsrichtung des Luftauslassrahmens verlaufenden, abschnittsweise verstellbaren Luftlenklamellen und mit einem Schieber, der verteilkastenseitig vom Luftauslassrahmen angeordnet ist, sich über die gesamte Länge des Luftauslassrahmens erstreckt, in Längsrichtung verschiebbar ist und Abdeckflächen aufweist, deren Grösse dem Austrittsquerschnitt der Austrittsöffnungen entspricht und dem Abstand der Austrittsöffnungen angepasst ist.The invention relates to an air outlet device for ventilation of rooms with a distribution box that can be connected to an air inlet duct, with an air outlet frame leading from the distribution box to the room, with outlet openings dividing the air outlet frames in the longitudinal direction, with sectionally adjustable air deflection slats running in the longitudinal direction of the air outlet frame, and with a slide , which is arranged on the distribution box side of the air outlet frame, extends over the entire length of the air outlet frame, can be displaced in the longitudinal direction and has cover surfaces whose size corresponds to the outlet cross section of the outlet openings and is adapted to the spacing of the outlet openings.

Eine solche Luftauslassvorrichtung ist aus der CH-A-594 179 bekannt. Bei dieser bekannten Luftauslassvorrichtung wird der Luftauslassrahmen von einem in Längsrichtung durchgehenden Hohlprofil gebildet, dessen Oberseite von Luftaustrittsöffnungen durchbrochen ist, so dass die aus dem Luftauslassrahmen austretende Luft in einzelne Luftstrahlen unterteilt wird. Die in dem Hohlprofil angeordneten Luftlenklamellen erstrecken sich in Längsrichtung über mehrere dieser Austrittsöffnungen, so dass sie die Luftstrahlen dieser Austrittsöffnungen ablenken. Die im Bereich dieser Luftlenklamellen angeordneten Austrittsöffnungen dienen zum Einblasen von Kaltluft zum Kühlen des Raumes. Durch die Luftlenklamellen kann die Kaltluft nämlich unter einem Winkel von weniger als 45° entlang der Raumdecke eingeblasen werden, so dass unangenehme Zuglufterscheinungen vermieden werden. Im Bereich der anderen Austrittsöffnungen sind keine Luftlenklamellen vorgesehen, so dass durch diese Austrittsöffnungen die Luft senkrecht in den Raum eingeblasen wird. Diese Austrittsöffnungen dienen zum Einblasen von Warmluft für das Heizen des Raumes. Die Warmluft soll nämlich möglichst senkrecht in den Raum eingeblasen werden, damit sie weit genug in die Aufenthaltszone des Raumes eindringt.Such an air outlet device is known from CH-A-594 179. In this known air outlet device, the air outlet frame is formed by a hollow profile which is continuous in the longitudinal direction, the upper side of which is penetrated by air outlet openings, so that the air emerging from the air outlet frame is divided into individual air jets. The air deflection lamellae arranged in the hollow profile extend in the longitudinal direction over a plurality of these outlet openings, so that they deflect the air jets of these outlet openings. The outlet openings arranged in the area of these air deflection lamellae serve to blow in cold air to cool the room. The air deflection blades allow the cold air to be blown in at an angle of less than 45 ° along the ceiling, so that unpleasant drafts are avoided. In the area of the other outlet openings there are no air deflection slats, so that the air is blown vertically into the room through these outlet openings. These outlet openings are used to blow in warm air for heating the room. The warm air should be blown into the room as vertically as possible so that it penetrates far enough into the room's lounge area.

Der gegenüber dem Hohlprofil des Luftauslassrahmens verschiebbare Schieber weist Schlitze und zwischen diesen liegende Abdeckflächen auf, die dem Austrittsquerschnitt der Austrittsöffnungen in Grösse und Abstand entsprechen. Diese Schlitze und Abdeckflächen sind entsprechend den Warmluft- bzw. Kaltluftabschnitten gruppenweise gegeneinander versetzt, so dass je nach Schiebereinstellung nur die Warmluftaustrittsöffnungen bzw. die Kaltluftaustrittsöffnungen freigegeben und die jeweils anderen Öffnungen abgedeckt werden. Durch Verschieben des Schiebers kann die Luftauslassvorrichtung auf diese Weise zwischen Sommerbetrieb zum Einblasen von Kaltluft und Winterbetrieb zum Einblasen von Warmluft umgeschaltet werden.The slide, which is displaceable with respect to the hollow profile of the air outlet frame, has slots and cover surfaces lying between them, which correspond in size and distance to the outlet cross section of the outlet openings. These slots and cover surfaces are offset from one another in groups in accordance with the hot air or cold air sections, so that, depending on the slide setting, only the hot air outlet openings or the cold air outlet openings are released and the respective other openings are covered. By moving the slide, the air outlet device can be switched between summer operation for blowing in cold air and winter operation for blowing in warm air.

Bei dieser bekannten Luftauslassvorrichtung sind sowohl beim Kaltluft- als auch beim Warmluftbetrieb jeweils nur Teilabschnitte ihrer Gesamtlängsausdehnung wirksam. Eine gleichmässige Verteilung der eingeblasenen Luft über die gesamte Länge der Luftauslassvorrichtung ist nicht möglich, was insbesondere im Kaltluftbetrieb störend ist, wo die Kaltluftstrahlen entlang der Raumdecke abwechselnd in entgegengesetzte Richtungen eingeblasen werden. Eine Verbesserung ist nicht möglich, da nur bei einer ausreichenden Längsausdehnung der Luftlenklamellen eine genügende Trennung zwischen der abgelenkten Einblasrichtung und der unabgelenkten Einblasrichtung möglich ist.In this known air outlet device, only partial sections of their total longitudinal expansion are effective in both cold air and hot air operation. A uniform distribution of the blown air over the entire length of the air outlet device is not possible, which is particularly troublesome in cold air operation, where the cold air jets are blown in alternately in opposite directions along the ceiling. An improvement is not possible, since a sufficient separation between the deflected direction of injection and the undeflected direction of injection is only possible with a sufficient longitudinal expansion of the air deflection blades.

Eine Luftmengeneinstellung ist ebenfalls nicht möglich. Der Schieber kann nur zwischen zwei Stellungen verschoben werden, in denen entweder die Kaltluftaustrittsöffnungen oder die Warmluftaustrittsöffnungen vollständig verschlossen sind. Bei einer Zwischenstellung werden sowohl die Warmluft- als auch die Kaltluftaustrittsöffnungen teilweise freigegeben, so dass der gesamte Austrittsquerschnitt nicht verringert wird, die Einblasrichtungen jedoch in unerwünschter Weise miteinander vermischt werden. Eine Anpassung der Luftmenge an den jeweiligen Bedarf ist bei dieser bekannten Luftauslassvorrichtung nur dadurch möglich, dass der Luftvolumenstrom bereits vor der Luftauslassvorrichtung gesteuert wird. Bei einer Reduzierung des Volumenstromes nimmt dabei allerdings die Ausblasgeschwindigkeit ab, da der gesamte Austrittsquerschnitt der Luftauslassvorrichtung nicht verändert werden kann. Die Verringerung der Ausblasgeschwindigkeit hat zur Folge, dass bei Einblasen kalter Luft diese in die Aufenthaltszone fällt und unangenehme Zugerscheinungen hervorruft. Beim Einblasen warmer Luft hat dagegen die verringerte Ausblasgeschwindigkeit zur Folge, dass die warme Luft nicht weit genug in die Aufenthaltszone des Raumes eindringt, so dass die Erwärmung des Raumes ungenügend bleibt.An air volume setting is also not possible. The slide can only be moved between two positions in which either the cold air outlet openings or the warm air outlet openings are completely closed. In an intermediate position, both the hot air and the cold air outlet openings are partially released, so that the entire outlet cross section is not reduced, but the blowing directions are mixed with one another in an undesirable manner. With this known air outlet device, an adjustment of the air quantity to the respective requirement is only possible in that the air volume flow is controlled before the air outlet device. When the volume flow is reduced, however, the blow-out speed decreases, since the entire outlet cross section of the air outlet device cannot be changed. The reduction in the blow-out speed means that when cold air is blown in, it falls into the occupied zone and causes unpleasant drafts. When blowing in warm air, on the other hand, the reduced blow-out speed means that the warm air does not penetrate far enough into the lounge area of the room, so that the heating of the room remains insufficient.

Diese bekannte Luftauslassvorrichtung eignet sich daher nur ungenügend für neuere Klimaanlagen, bei denen bevorzugt eine Temperaturregelung in den zu klimatisierenden Räumen durch Änderung des zugeführten Luftvolumens bei konstanter Zulufttemperatur und nicht eine Änderung der Zulufttemperatur bei konstantem Zuluftvolumen angestrebt wird, da auf diese Weise mit den geringsten Energieverlusten gearbeitet werden kann.This known air outlet device is therefore unsuitable for newer air conditioning systems, in which temperature control in the rooms to be air-conditioned is preferably sought by changing the air volume supplied at a constant supply air temperature and not a change in the supply air temperature at a constant supply air volume, since this results in the least energy losses can be worked.

Aus der DE-A-25 25 196 ist eine Luftauslassvorrichtung bekannt, bei welcher der Luftauslassrahmen durch Querstege in einzelne Austrittsöffnungen bildende Schächte unterteilt ist. In den Schächten sind einzeln verstellbare Luftlenklamellen angeordnet, wodurch ein den jeweiligen Betriebsbedingungen angepasstes gleichmässiges Einblasen der Zuluft in den Raum möglich ist. Eine Änderung des Austrittsquerschnitts und damit eineAnpassung an unterschiedlicheZuluftvolumenströme ist nicht möglich.An air outlet device is known from DE-A-25 25 196, in which the air outlet frame is divided into shafts forming individual outlet openings by transverse webs. Individually adjustable air deflection slats are arranged in the shafts, making it possible to blow the supply air evenly into the room to suit the respective operating conditions. A change in the outlet cross section and there with an adaptation to different supply air volume flows is not possible.

Aus der DE-19 29 015 ist eine Luftauslassvorrichtung bekannt, bei welcher der Luftauslassrahmen durch ein Hohlprofil gebildet ist, das an seiner Oberseite durch ein Von Luftaustrittsöffnungen durchbrochenes Blech abgedeckt ist. Gegen dieses mit den Luftauslassöffnungen versehene Blech ist ein mit entsprechenden Öffnungen versehener Schieber verschiebbar angeordnet, der eine in Längsrichtung durchgehende Luftlenklamelle trägt. Mittels des Schiebers ist der Austrittsquerschnitt der Luftaustrittsöffnungen verstellbar, während die Luftlenklamelle eine Verstellung der Ausblasrichtung erlaubt. Diese Luftauslassvorrichtung ermöglicht eine Anpassung des Austrittsquerschnitts an den erforderlichen Zuluftvolumenstrom. Aufgrund der durchgehenden Luftleitlamelle ist jedoch nur eine einzige Einblasrichtung für den gesamten Zuluftstrom möglich, so dass keine gleichmässige Verteilung der eingeblasenen Zuluft erreicht werden kann.From DE-19 29 015 an air outlet device is known, in which the air outlet frame is formed by a hollow profile which is covered on its upper side by a sheet metal perforated by air outlet openings. A slide provided with corresponding openings is displaceably arranged against this sheet metal provided with the air outlet openings and bears an air deflection lamella which is continuous in the longitudinal direction. The outlet cross-section of the air outlet openings can be adjusted by means of the slide, while the air-deflecting lamella allows the outlet direction to be adjusted. This air outlet device enables the outlet cross section to be adapted to the required supply air volume flow. Due to the continuous air guide lamella, however, only one blowing direction is possible for the entire supply air flow, so that a uniform distribution of the blown supply air cannot be achieved.

Aus der DE-A-26 08 053 ist eine Luftauslassvorrichtung bekannt, deren Luftauslassrahmen abwechselnd nach rechts und nach links unter 45° zur Raumdecke gerichtete Auslassöffnungen aufweist. DerAustrittsquerschnittdieserAuslass- öffnungen kann durch einen Schieber entsprechend dem Zuluftvolumenstrom geändert werden. Diese Luftauslassvorrichtung eignet sich nur zum Einblasen von Kaltluft mit einem der Kühllast angepassten Zuluftvolumenstrom und konstanter Einblasgeschwindigkeit. Ein Einblasen von Warmluft zum Beheizen des Raumes im Winterbetrieb ist nicht möglich.An air outlet device is known from DE-A-26 08 053, the air outlet frame of which alternately has outlet openings directed to the right and to the left at 45 ° to the ceiling. The outlet cross-section of these outlet openings can be changed by a slide according to the supply air volume flow. This air outlet device is only suitable for blowing in cold air with a supply air volume flow adapted to the cooling load and constant blowing speed. It is not possible to blow in warm air to heat the room in winter operation.

Der Erfindung liegt die Aufgabe zugrunde, eine Luftauslassvorrichtung zu schaffen, die Warmluft und Kaltluft mit einem der jeweiligen momentanen Wärmelast bzw. Kühllast angepassten Volumenstrom einzublasen ermöglicht, ohne dass sich die optimale Austrittsgeschwindigkeit und die gleichmässige Verteilung der eingeblasenen Zuluft ändert.The invention has for its object to provide an air outlet device which allows hot air and cold air to be blown in with a volume flow adapted to the respective instantaneous heat load or cooling load, without the optimal exit velocity and the uniform distribution of the blown supply air changing.

Diese Aufgabe wird bei einer Luftauslassvorrichtung der eingangs genannten Gattung erfindungsgemäss dadurch gelöst, dass der Luftauslassrahmen durch Querstege in die Austrittsöffnungen bildende Schächte unterteilt ist, dass die Luftlenklamellen in den Schächten einzeln verstellbar angeordnet sind, dass ein zweiter und dritter Schieber vorgesehen sind, die in Längsrichtung verschiebbar gelagert sind, mit dem ersten Schieber gegen diesen verschiebbar in Verbindung stehen und Abdeckflächen aufweisen, deren Grösse dem Austrittsquerschnitt der Schächte entspricht, und dass der Abstand der Abdeckflächen der drei Schieber jeweils dem vierfachen Abstand der Schächte entspricht.This object is achieved according to the invention in an air outlet device of the type mentioned at the outset in that the air outlet frame is divided by transverse webs into the shafts forming the outlet openings, the air deflection lamellae are arranged individually adjustable in the shafts, and a second and third slide are provided in the longitudinal direction are slidably mounted, are slidably connected to the first slide against it and have cover surfaces whose size corresponds to the outlet cross section of the shafts, and that the distance between the cover surfaces of the three slides corresponds to four times the distance between the shafts.

Durch die drei Schieber und die Zuordnung ihrer Abdeckflächen zu den Schächten des Luftauslassrahmens ist es nicht nur möglich, den Austrittsquerschnitt des Luftauslassrahmens dem jeweiligen Zuluftvolumenstrom anzupassen, so dass die Austrittsgeschwindigkeit der eingeblasenen Luft konstant bleibt. Es ist ausserdem möglich, die gleichmässige Verteilung der eingeblasenen Zuluft auch bei einer Änderung des Volumenstromes aufrechtzuerhalten. Dazu sind die Luftlenklamellen in entsprechender Anordnung so eingestellt, dass sie abwechselnd in entgegengesetzter Richtung entlang der Raumdecke bzw. senkrecht zur Raumdecke einblasen. Durch Verschieben der Schieber können dann kontinuierlich jeweils Schächte mit den verschieden eingestellten Luftlenklamellen in gleicher Anzahl und in gleichmässiger Verteilung über die Gesamtlängsausdehnung des Luftauslassrahmens abgedeckt werden. Die verbleibenden offenen Schächte weisen dann noch immer das gleiche Verhältnis von in die verschiedenen Richtungen eingestellten Luftlenklamellen auf.The three sliders and the assignment of their cover surfaces to the shafts of the air outlet frame not only make it possible to adapt the outlet cross section of the air outlet frame to the respective supply air volume flow, so that the outlet velocity of the air blown in remains constant. It is also possible to maintain the uniform distribution of the injected supply air even when the volume flow changes. For this purpose, the air deflection slats are set in such a way that they blow in alternately in the opposite direction along the ceiling or perpendicular to the ceiling. By moving the slide, shafts with the differently adjusted air deflection blades in the same number and in an even distribution over the entire longitudinal extent of the air outlet frame can then be covered continuously. The remaining open shafts then still have the same ratio of air deflection blades set in the different directions.

Vorzugsweise ist der erste Schieber an einer ersten in Längsrichtung bewegbaren Schiebeplatte befestigt und der dritte Schieber steht mit dieser ersten Schiebeplatte in Verbindung und ist gegen diese in Längsrichtung beschränkt verschiebbar. Mittels der ersten Schiebeplatte kann dabei die gesamte Schieberanordnung zwischen den dem Warmluft- bzw. Winterbetrieb und dem Kaltluft- bzw. Sommerbetrieb entsprechenden Grundeinstellungen verschoben werden.The first slide is preferably fastened to a first sliding plate that can be moved in the longitudinal direction, and the third slide is connected to this first sliding plate and can be displaced in the longitudinal direction to a limited extent. By means of the first sliding plate, the entire slide arrangement can be shifted between the basic settings corresponding to warm air or winter operation and cold air or summer operation.

In einer vorteilhaften Ausführungsform ist der dritte Schieber an einer zweiten Schiebeplatte befestigt, die auf dieser ersten Schiebeplatte in Längsrichtung verschiebbar gelagert ist, und der zweite Schieber weist Mitnehmerlaschen auf, die mit einer an eine seiner Abdeckflächen angrenzenden Kante und mit einer gegen diese Kante um zwei Schachtabstände versetzten Kante in den dritten Schieber und mit gegen diese zwei Kanten jeweils um eine Schachtbreite versetzten zwei weiteren Kanten in den ersten Schieber eingreifen. In dieser Ausführungsform ist zur Veränderung des Austrittsquerschnitts nur eine Betätigung des dritten Schiebers mittels der zweiten Schiebeplatte erforderlich, während der zweite Schieber durch die zwei anderen Schieber jeweils zwangsläufig mitgenommen wird.In an advantageous embodiment, the third slide is fastened to a second sliding plate, which is mounted on this first sliding plate so that it can be moved in the longitudinal direction, and the second slide has driver tabs, which have an edge adjoining one of its cover surfaces and one against this edge by two Shaft distances offset edge engage in the third slide and with two further edges offset against these two edges by one shaft width each engage in the first slide. In this embodiment, only an actuation of the third slide by means of the second slide plate is required to change the outlet cross section, while the second slide is inevitably taken along by the two other slides.

Eine konstruktiv besonders einfache Ausführung der Luftauslassvorrichtung ergibt sich, wenn die Schiebeplatten in dem Verteilkasten angeordnet sind, wobei der erste Schieber mittels einer Lasche an der ersten Schiebeplatte und der dritte Schieber mittels einer Lasche an der zweiten Schiebeplatte befestigt sein können.A structurally particularly simple design of the air outlet device is obtained if the sliding plates are arranged in the distribution box, the first slide being able to be fastened to the first sliding plate by means of a strap and the third slider can be fastened to the second sliding plate by means of a strap.

Die Luftauslassvorrichtung eignet sich hervorragend für den automatischen Betrieb. Dazu sind die Schieber vorzugsweise mittels thermostatisch gesteuerter Stellmotoren verschiebbar. Ein erster am Verteilkasten angebrachter Stellmotor greift an der ersten Schiebeplatte an, um die gesamte Luftauslassvorrichtung zwischen Warmluft- und Kaltluftbetrieb umzuschalten, und ein zweiter an der ersten Schiebeplatte angebrachter Stellmotor greift an der zweiten Schiebeplatte an, um den Austrittsquerschnitt mittels des zweiten und des dritten Schiebers der jeweiligen Volumenstromänderung anzupassen.The air outlet device is ideal for automatic operation. For this purpose, the slides are preferably displaceable by means of thermostatically controlled servomotors. A first servomotor attached to the distribution box engages the first sliding plate to switch the entire air outlet device between hot air and cold air operation, and a second servomotor attached to the first sliding plate engages the second sliding plate to adjust the outlet cross section by means of the second and third sliders to adapt to the respective volume flow change.

Die Anordnung der Stellmotoren in dem Verteilkasten führt ausserdem zu einem kompakten Aufbau der gesamten Luftauslassvorrichtung, was eine einfache Montage und einen platzsparenden Einbau in die Raumdecke gewährleistet.The arrangement of the servomotors in the Ver Sub-box also leads to a compact structure of the entire air outlet device, which ensures simple assembly and space-saving installation in the ceiling.

Im folgenden wird die Erfindung anhand eines in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert. Es zeigen:

  • Fig. 1 einen Längsschnitt durch die Luftauslassvorrichtung dieses Ausführungsbeispiels gemäss der Linie B-B der Fig. 2,
  • Fig. 2 einen Querschnitt durch die Luftauslassvorrichtung gemäss der Linie A-A der Fig. 1,
  • Fig. 3 einen vergrösserten Ausschnitt der Fig. 1,
  • Fig. 4 schematisch verschiedene Stellungen der Luftauslassvorrichtung in Draufsicht und
  • Fig. 5 verschiedene Stellungen der Luftauslassvorrichtung in Seitenansicht.

Wie die Fig. 1 und 2 zeigen, besteht die Luftauslassvorrichtung aus einem langgestreckten quaderförmigen Verteilkasten 10, der über einen Stutzen 12 an einem nicht dargestellten Zuluftkanal der Klimaanlage angeschlossen wird. Eine im Inneren des Verteilkastens 10 angebrachte Klappe 14, die als Lochplatte ausgebildet ist, dient zur besseren Verteilung der durch den Stutzen 12 in den Verteilkasten einströmenden Zuluftmenge.The invention is explained in more detail below with reference to an embodiment shown in the drawing. Show it:
  • 1 shows a longitudinal section through the air outlet device of this embodiment according to line BB of FIG. 2,
  • 2 shows a cross section through the air outlet device according to line AA of FIG. 1,
  • 3 shows an enlarged section of FIG. 1,
  • Fig. 4 shows schematically different positions of the air outlet device in plan view and
  • Fig. 5 different positions of the air outlet device in side view.

1 and 2 show, the air outlet device consists of an elongated cuboid-shaped distribution box 10 which is connected via a connecting piece 12 to a supply air duct (not shown) of the air conditioning system. A flap 14 attached in the interior of the distribution box 10, which is designed as a perforated plate, serves for better distribution of the amount of supply air flowing through the nozzle 12 into the distribution box.

An den Verteilkasten 10 schliesst sich ein Luftauslassrahmen 16 an, der sich über die gesamte Länge des Verteilkastens 10 erstreckt und in den zu belüftenden Raum mündet. Der Auslassrahmen 16 ist durch Querstege 18 in seiner Längsrichtung in einzelne Schächte 20 unterteilt. Auf einer über die gesamte Länge des Auslassrahmens 16 durchgehenden Achse sitzen in den Schächten 20 jeweils Luftlenklamellen 22, die sich unmittelbar vor der Austrittsöffnung der Schächte 20 befinden und auf der Achse unabhängig voneinander verschwenkbar sind, so dass die aus den Schächten 20 austretenden Luftstrahlen unabhängig voneinander durch die Lamellen 22 gerichtet werden können.An air outlet frame 16 connects to the distribution box 10 and extends over the entire length of the distribution box 10 and opens into the space to be ventilated. The outlet frame 16 is divided by longitudinal webs 18 into individual shafts 20 in its longitudinal direction. On an axis extending over the entire length of the outlet frame 16, in the shafts 20 there are in each case air-deflecting fins 22 which are located directly in front of the outlet opening of the shafts 20 and can be pivoted independently of one another on the axis, so that the air jets emerging from the shafts 20 are independent of one another can be directed through the slats 22.

Auf der dem Verteilkasten 10 zugewandten Seite des Auslassrahmens 16 sind übereinander drei Schieber 24, 26 und 28 angeordnet. Die Schieber sind an den Längsseiten des Auslassrahmens 16 gleitend geführt, so dass sie in Längsrichtung des Auslassrahmens gegen diesen und gegeneinander verschiebbar sind. Die Schieber 24, 26 und 28 erstrecken sich über die gesamte Länge des Auslassrahmens 16 und weisen jeweils im vierfachen Abstand der Schächte 20 Abdeckflächen 30,32 bzw. 34 auf. Die Abdeckflächen 30, 32 und 34 entsprechen in ihrer Grösse jeweils dem Austrittsquerschnitt der Schächte 20. Jeder Schieber 24, 26 bzw. 28 kann also mit seinen Abdeckflächen 30, 32 bzw. 34 jeweils jeden vierten Schacht 20 verschliessen, während er die drei dazwischen liegenden Schächte 20 offen lässt.On the side of the outlet frame 16 facing the distribution box 10, three slides 24, 26 and 28 are arranged one above the other. The slides are slidably guided on the longitudinal sides of the outlet frame 16 so that they can be displaced in the longitudinal direction of the outlet frame against and against one another. The slides 24, 26 and 28 extend over the entire length of the outlet frame 16 and each have 20 cover surfaces 30, 32 and 34 at four times the spacing of the shafts. The size of the cover surfaces 30, 32 and 34 corresponds in each case to the outlet cross section of the shafts 20. Each slide 24, 26 and 28 can therefore close every fourth shaft 20 with its cover surfaces 30, 32 and 34, respectively, while holding the three in between Shafts 20 leaves open.

Der erste Schieber 24 ist mittels einer Lasche 36 an einer ersten Schiebeplatte 38 befestigt, die in Längsrichtung verschiebbar in dem Verteilkasten 10 gelagert ist.The first slide 24 is fastened by means of a tab 36 to a first sliding plate 38 which is mounted in the distribution box 10 so as to be displaceable in the longitudinal direction.

Mittels eines ebenfalls in dem Verteilkasten 10 angeordneten, thermostatisch gesteuerten Stellmotors 40 ist die Schiebeplatte 38 und mit dieser der erste Schieber 24 um einen Schachtabstand verschiebbar.By means of a thermostatically controlled servomotor 40 likewise arranged in the distribution box 10, the sliding plate 38 and with it the first slide 24 can be displaced by a shaft distance.

Auf der ersten Schiebeplatte 38 ist eine zweite Schiebeplatte 42 angebracht und mittels einer Schlitzführung 44 in Längsrichtung gegen die erste Schiebeplatte 38 um zwei Schachtabstände verschiebbar. Die Verschiebung der zweiten Schiebeplatte 42 erfolgt durch einen zweiten thermostatisch gesteuerten Stellmotor 46, der an der ersten Schiebeplatte 38 befestigt ist.A second sliding plate 42 is attached to the first sliding plate 38 and can be displaced in the longitudinal direction against the first sliding plate 38 by two slot distances by means of a slot guide 44. The second sliding plate 42 is displaced by a second thermostatically controlled servomotor 46, which is fastened to the first sliding plate 38.

Der dritte Schieber 28 ist mittels einer Lasche 48 an der zweiten Schiebeplatte 42 befestigt. Der dritte Schieber ist somit mittels des Stellmotors 46 und der zweiten Schiebeplatte 42 gegenüber dem mit der ersten Schiebeplatte 38 verbundenen ersten Schieber 24 um zwei Schachtabstände verschiebbar.The third slide 28 is fastened to the second slide plate 42 by means of a tab 48. The third slide can thus be displaced by two shaft distances by means of the servomotor 46 and the second slide plate 42 in relation to the first slide 24 connected to the first slide plate 38.

Wie Figur 3 zeigt, weist der zweite Schieber 26 zwei Paare von Mitnehmerlaschen 50 und 52 auf. Die zwei Mitnehmerlaschen 50 erstrecken sich jeweils in Längsrichtung über eine Schachtbreite und sind in Längsrichtung um zwei Schachtabstände gegeneinander versetzt. Die linke Mitnehmerlasche 50 greift nach unten in den ersten Schieber 24, während die rechte Mitnehmerlasche 50 nach oben in den dritten Schieber 28 eingreift. Die zwei Mitnehmerlaschen 52 sind zwischen den Mitnehmerlaschen 50 angeordnet und erstrecken sich in Längsrichtung jeweils über eine halbe Schachtbreite. Die linke Mitnehmerlasche 52 greift nach oben in den dritten Schieber 28 ein, während die rechte Mitnehmerlasche 52 nach unten in den ersten Schieber 24 eingreift.As FIG. 3 shows, the second slide 26 has two pairs of driver plates 50 and 52. The two driver plates 50 each extend in the longitudinal direction over a shaft width and are offset from one another in the longitudinal direction by two shaft distances. The left driver tab 50 engages downward in the first slide 24, while the right driver tab 50 engages upward in the third slide 28. The two driver plates 52 are arranged between the driver plates 50 and each extend in the longitudinal direction over half a shaft width. The left driver tab 52 engages upward in the third slide 28, while the right driver tab 52 engages downward in the first slide 24.

Die Funktionsweise der Luftauslassvorrichtung wird am folgenden anhand der Figuren 4 und 5 erläutert:

  • In Fig. 4 ist eine Draufsicht auf den Auslassrahmen 16 schematisch dargestellt. Die Luftlenklamellen 22 der einzelnen Schächte 20 sind dabei in der Darstellung der Fig. 4 von links beginnend folgendermassen eingestellt:
    • 1. Schacht: Luftstrom wird senkrecht nach unten eingeblasen (in Fig. 4 durch s gekennzeichnet)
    • 2. Schacht: Die Luft wird flach unter der Decke nach links eingeblasen (in Fig. 4 durch einen Pfeil dargestellt)
    • 3. Schacht: Die Luft wird flach unter der Decke nach rechts eingeblasen
    • 4. Schacht: Die Luft wird flach unter der Decke nach links eingeblasen
    • 5. Schacht: Die Luft wird senkrecht nach unten eingeblasen
    • 6. Schacht: Die Luft wird flach unter der Decke nach rechts eingeblasen usw.
The operation of the air outlet device is explained below with reference to FIGS. 4 and 5:
  • FIG. 4 schematically shows a top view of the outlet frame 16. The air deflection slats 22 of the individual shafts 20 are set as follows in the illustration in FIG. 4, starting from the left:
    • 1st duct: air flow is blown vertically downwards (marked by s in Fig. 4)
    • 2. Shaft: The air is blown in flat under the ceiling to the left (shown by an arrow in Fig. 4)
    • 3rd shaft: The air is blown flat under the ceiling to the right
    • 4. Shaft: The air is blown in flat under the ceiling to the left
    • 5. Shaft: The air is blown in vertically downwards
    • 6th shaft: The air is blown flat under the ceiling to the right, etc.

Die oberste Darstellung der Fig. 4 zeigt die Luftauslassvorrichtung im Sommerbetrieb bei voller Wärmebelastung. Die erste Schiebeplatte 38 ist durch den Stellmotor 40 nach links geschoben, so dass der erste Schieber 24 mit seinen Abdeckflächen 30 sämtliche Schächte 20 verschliesst, deren Luftlenklamelle 22 senkrecht nach unten blasend eingestellt ist. Diese Stellung der ersten Schiebeplatte 38 bzw. des ersten Schiebers 24 entspricht dem Sommerbetrieb, da nur Warmluft zur Heizung senkrecht nach unten in den Raum eingeblasen wird, während die Kaltluft zur Kühlung unter einem Winkel von weniger als 45° flach an der Decke eingeblasen wird.The uppermost representation of FIG. 4 shows the air outlet device in summer operation with full heat load. The first sliding plate 38 is pushed to the left by the servomotor 40, so that the first slide 24 closes all shafts 20 with its cover surfaces 30, the air deflection lamella 22 of which is set to blow vertically downwards. This position of the first sliding plate 38 or the first Slider 24 corresponds to summer operation, since only warm air for heating is blown vertically down into the room, while the cold air for cooling is blown flat at an angle of less than 45 ° on the ceiling.

In der obersten Darstellung der Figur 4 sind ausserdem auch der zweite und dritte Schieber 26 und 28 vollständig nach links geschoben, so dass deren Abdeckflächen 32 bzw. 34 mit den Abdeckflächen 30 des ersten Schiebers 24 zur Dekkung kommen. Durch alle drei Schieber 24, 26 und 28 werden somit nur die senkrecht nach unten blasenden Schächte verschlossen. Die zwischen diesen liegenden Schächte 20, die aufgrund der Einstellung ihrer Luftlenklamellen 22 flach unter der Decke ausblasen, sind vollständig offen. Es kann somit mit max. Austrittsquerschnitt kalte Zuluft in den Raum eingeblasen werden. Bei diesem Zustand mit max. Kaltluft-Volumenstrom wird somit die Luftauslassvorrichtung mit ihrer vollen Kühlleistung von 100% betrieben.In the uppermost illustration in FIG. 4, the second and third slides 26 and 28 are also pushed completely to the left, so that their cover surfaces 32 and 34 come to cover with the cover surfaces 30 of the first slide 24. With all three slides 24, 26 and 28, only the shafts blowing vertically downwards are closed. The shafts 20 lying between them, which blow out flat under the ceiling due to the setting of their air deflection blades 22, are completely open. It can therefore be operated with a max. Outlet cross-section of cold supply air can be blown into the room. In this condition with max. Cold air volume flow thus operates the air outlet device with its full cooling capacity of 100%.

Das Verschieben des zweiten und dritten Schiebers 26 bzw. 28 nach links erfolgt mittels des zweiten Stellmotors 46, der die zweite Schiebeplatte 42 nach links verschiebt. Dabei wird zunächst der dritte Schieber 28 nach links verschoben, bis seine Abdeckfläche 34 an der rechten Mitnehmerlasche 50 anschlägt, worauf bei der Weiterbewegung nach links auch der zweite Schieber 26 mitgenommen wird.The second and third sliders 26 and 28 are moved to the left by means of the second servomotor 46, which moves the second sliding plate 42 to the left. First, the third slider 28 is shifted to the left until its cover surface 34 abuts the right driving tab 50, whereupon the second slider 26 is also carried along when moving further to the left.

Nimmt im Sommerbetrieb die Wärmelast des zu belüftenden Raumes ab, so wird thermostatisch durch die Raumtemperatur gesteuert der zweite Stellmotor 46 betätigt und zieht die zweite Schiebeplatte 42 nach rechts. Dadurch wird zunächst der dritte Schieber 28 nach rechts bewegt, wobei er zunächst fortschreitend den Austrittsquerschnitt der Schächte verschliesst, die sich rechts an die senkrecht nach unten ausblasenden Schächte anschliessen. Ist der dritte Schieber 28 um eine Schachtweite nach rechts verschoben, so kommt seine Abdeckfläche 34 an der linken Mitnehmerlasche 52 zum Anschlag, so dass bei der weiteren Bewegung der zweiten Schiebeplatte 42 nach rechts auch der zweite Schieber 26 mitgenommen wird.If the heat load of the room to be ventilated decreases in summer operation, the second servomotor 46 is actuated thermostatically by the room temperature and pulls the second sliding plate 42 to the right. As a result, the third slide 28 is first moved to the right, initially progressively closing the outlet cross section of the shafts which adjoin the shafts which blow out vertically downward on the right. If the third slide 28 is shifted to the right by a shaft width, its cover surface 34 comes to a stop on the left driver plate 52, so that the second slide 26 is also carried along when the second slide plate 42 moves to the right.

Ist die zweite Schiebeplatte 42 durch den Stellmotor 46 vollständig um zwei Schachtabstände nach rechts verschoben, so wird die Stellung eingenommen, die in Figur 4 in der zweiten Zeile von oben schematisch gezeigt ist und die auch in Figur 1 dargestellt ist. Der erste Schieber 24 verschliesst die senkrecht nach unten blasenden Schächte, während der zweite Schieber 26 die rechts daran anschliessenden nächsten und der dritte Schieber 28 die rechts daran anschliessenden übernächsten seitlich ausblasenden Schächte verschliessen. Es bleibt somit nur jeder vierte seitlich ausblasende Schacht offen. Der Austrittsquerschnitt des gesamten Auslassrahmens ist somit entsprechend dem reduzierten Volumenstrom verringert. Die Kaltluft wird in reduzierter Menge, jedoch mit unveränderter Austrittsgeschwindigkeit eingeblasen. Die Kühlleistung ist dabei auf 40% reduziert.If the second sliding plate 42 is completely shifted to the right by two shaft distances by the servomotor 46, the position is assumed which is shown schematically in the second line from above in FIG. 4 and which is also shown in FIG. 1. The first slide 24 closes the vertically downwardly blowing ducts, while the second slider 26 closes the next ducts which blow out to the right and the third slider 28 closes the blowers which blow out next to it on the right. Only every fourth side-venting shaft remains open. The outlet cross section of the entire outlet frame is thus reduced in accordance with the reduced volume flow. The cold air is blown in in a reduced quantity, but with the outlet speed unchanged. The cooling capacity is reduced to 40%.

In Figur 5 ist in der oberen Darstellung die Einblasrichtung der Luftstrahlen im Sommerbetrieb dargestellt. Die Luftstrahlen verlaufen abwechselnd nach beiden Seiten flach an der Raumdekke. Senkrecht nach unten wird keine Luft eingeblasen, um unangenehme Zugerscheinungen zu vermeiden, da die Zuluft im Sommerbetrieb eine niedrigere Temperatur als die Raumluft aufweist.In Figure 5, the blowing direction of the air jets in summer operation is shown in the upper representation. The air jets run alternately flat on both sides of the ceiling. No air is blown vertically downwards to avoid unpleasant drafts, since the supply air in summer is at a lower temperature than the room air.

Im Winterbetrieb, d.h. wenn die Temperatur der Zuluft über der Raumluft liegt, wird die erste Schiebeplatte 38 durch den ersten Stellmotor 40 um einen Schachtabstand nach rechts verschoben. Dadurch gibt der erste Schieber 24 die senkrecht nach unten blasenden Schächte 20 frei. Bei dieser Verschiebung wird der dritte Schieber 28 durch die auf der ersten Schiebeplatte 38 angebrachte zweite Schiebeplatte 42 mitgenommen.In winter operation, i.e. if the temperature of the supply air is above the room air, the first slide plate 38 is shifted to the right by a shaft distance by the first servomotor 40. As a result, the first slide 24 releases the shafts 20 which blow vertically downwards. During this displacement, the third slide 28 is carried along by the second slide plate 42 attached to the first slide plate 38.

Der zweite Schieber 26 wird, falls sich die Schieber in der in Figur 3 dargestellten Stellung befinden, dadurch mitgenommen, dass die Abdeckfläche 34 des dritten Schiebers 28 an der linken Mitnehmerlasche 52 anschlägt. Falls sich die Schieber dagegen in der Stellung befinden, in welcher ihre Abdeckflächen 30, 32, 34 zusammenfallen, so wird der zweite Schieber 26 dadurch mitgenommen, dass die Abdeckfläche 30 des ersten Schiebers 24 gegen die linke Mitnehmerlasche 50 anschlägt.If the slides are in the position shown in FIG. 3, the second slider 26 is carried along in that the cover surface 34 of the third slider 28 strikes the left driver plate 52. If, on the other hand, the slides are in the position in which their cover surfaces 30, 32, 34 coincide, then the second slide 26 is carried along in that the cover surface 30 of the first slider 24 strikes against the left driving plate 50.

Je nach der Wärmelast des zu belüftenden Raumes wird nun die zweite Schiebeplatte 42 durch den zweiten Stellmotor 46 verschoben, so dass sich die Stellung des zweiten Schiebers 26 und des dritten Schiebers 28 in der oben für den Sommerbetrieb beschriebenen Weise stufenlos ändert zwischen der in Figur 4 und in der dritten Zeile von oben dargestellten und der in Figur 4 in der untersten Zeile dargestellten Stellung.Depending on the heat load of the room to be ventilated, the second slide plate 42 is now displaced by the second servomotor 46, so that the position of the second slide 26 and the third slide 28 changes continuously in the manner described above for summer operation between that in FIG. 4 and in the third line from the top and the position shown in Figure 4 in the bottom line.

In der in der dritten Zeile dargestellten Stellung kommen die Abdeckflächen 30, 32 und 34 der drei Schieber zur Deckung, so dass jeweils nur jeder vierte Schacht geschlossen ist. In diesem Fall wird Warmluft senkrecht nach unten und nach beiden Seiten entlang der Raumdecke eingeblasen, wie die mittlere Darstellung der Fig. 5 zeigt. Die max. Heizleistung von 100% wird somit erreicht. In der in der untersten Zeile der Fig. 4 dargestellten Stellung werden durch die drei Schieber 24, 26 und 28 alle entlang der Raumdecke ausblasenden Schächte 20 verschlossen und nur die senkrecht nach unten ausblasenden Schächte bleiben offen. Warmluft wird daher nur senkrecht nach unten geblasen, wie in der unteren Darstellung der Fig. 5 gezeigt ist. Die Heizleistung ist auf 40% reduziert.In the position shown in the third line, the cover surfaces 30, 32 and 34 of the three slides come to coincide, so that only every fourth shaft is closed. In this case, warm air is blown vertically downwards and on both sides along the ceiling, as the middle illustration in FIG. 5 shows. The max. Heating output of 100% is thus achieved. In the position shown in the bottom line of FIG. 4, the three slides 24, 26 and 28 close all the ducts 20 which blow out along the ceiling and only the ducts which blow out vertically downwards remain open. Warm air is therefore only blown vertically downwards, as shown in the lower illustration in FIG. 5. The heating output is reduced to 40%.

Zum Umschalten vom Winterbetrieb auf den Sommerbetrieb wird die erste Schiebeplatte 38 durch den ersten Stellmotor 40 wieder in die in Fig. 1 dargestellte Stellung um einen Schachtabstand nach links verschoben. Der erste Schieber 24 wird dabei durch die erste Schiebeplatte 38 und der dritte Schieber 28 durch die zweite Schiebeplatte 42 mitgenommen. Der zweite Schieber 26 wird, falls sich die Schieber in der Stellung mit zusammenfallenden Abdeckflächen 30, 32, 34 befinden, dadurch nach links mitgenommen, dass die Abdeckfläche 34 des dritten Schiebers 28 gegen die rechte Mitnehmerlasche 50 anschlägt. Befinden sich die Schieber dagegen in der Stellung mit gegeneinander versetzten Abdeckflächen, so wird der zweite Schieber 26 dadurch mitgenommen, dass die Abdeckfläche 30 des ersten Schiebers 24 gegen die rechte Mitnehmerlasche 52 anschlägt.To switch from winter mode to summer mode, the first sliding plate 38 is shifted back to the position shown in FIG. 1 by a shaft distance to the left by the first servomotor 40. The first slide 24 is entrained by the first slide plate 38 and the third slide 28 by the second slide plate 42. The second slide 26 is, if the slide is in the position with coincident cover surfaces 30, 32, 34, thereby mitge to the left take that the cover surface 34 of the third slide 28 abuts against the right driving tab 50. If, on the other hand, the slides are in the position with mutually offset covering surfaces, then the second slider 26 is carried along in that the covering surface 30 of the first slider 24 abuts against the right driving plate 52.

Aus den Darstellungen der Fig. 4 und 5 gehen die Vorteile der erfindungsgemässen Luftauslassvorrichtung deutlich hervor. Im Sommerbetrieb, wenn Kaltluft eingeblasen wird, wird diese unabhängig von der Mengeneinstellung und dem Volumenstrom stets ausschliesslich entlang der Decke eingeblasen, um unangenehme Zugerscheinungen zu vermeiden. Das Einblasen erfolgt stets mit der gleichen Austrittsgeschwindigkeit, so dass ein Ablösen der Luftstrahlen von der Decke nicht auftritt. Der Austrittsquerschnitt des Auslassrahmens kann stufenlos entsprechend dem Volumenstrom geändert werden, wobei von der Luftauslassvorrichtung unabhängig von der Schieberstellung stets gleiche Luftmengen nach beiden Seiten eingeblasen werden, wie Fig. 4 zeigt. Die gleichmässige Luftverteilung bleibt also erhalten.The advantages of the air outlet device according to the invention are clearly evident from the illustrations in FIGS. 4 and 5. In summer operation, when cold air is blown in, it is always blown in exclusively along the ceiling, regardless of the quantity setting and the volume flow, in order to avoid unpleasant drafts. The blowing is always carried out at the same exit speed so that the air jets do not detach from the ceiling. The outlet cross section of the outlet frame can be changed continuously in accordance with the volume flow, the same amount of air being blown in from both sides by the air outlet device regardless of the slide position, as shown in FIG. 4. The even air distribution is therefore retained.

Im Winterbetrieb wird stets Warmluft senkrecht nach unten eingeblasen, während die Änderung des Volumenstroms zur Anpassung an die Wärmelast des Raumes sich nur auf die entlang der Raumdecke eingeblasenen Luftstrahlen auswirkt, wie aus Fig. 5 ersichtlich ist. Die Austrittsgeschwindigkeit der senkrecht nach unten eingeblasenen Warmluft und damit ihre Eindringtiefe in die Aufenthaltszone des Raumes bleibt stets konstant. Auch im Winterbetrieb ist bei stufenloser Verstellbarkeit der zugeführten Warmluftmenge stets gewährleistet, dass die Warmluft von der Luftauslassvorrichtung nach beiden Seiten gleichmässig verteilt eingeblasen wird.In winter operation, warm air is always blown vertically downwards, while the change in the volume flow to adapt to the heat load of the room only affects the air jets blown in along the ceiling, as can be seen in FIG. 5. The exit velocity of the warm air blown in vertically downwards and thus its depth of penetration into the occupied zone of the room always remains constant. Even in winter operation, with the infinitely variable adjustment of the amount of hot air supplied, it is always ensured that the hot air is blown in evenly distributed on both sides by the air outlet device.
