Abstract

A single flow of incoming air through a closed sound-absorbent air-conditioned ceiling is used for air conditioning a room. The flow of incoming air can be temperature controlled. Part of the flow of heat associated with the flow of incoming air is conveyed into the room in the form of heat radiation emitted from the air-conditioned ceiling. The air-conditioned ceiling is manufactured from materials with a high level of heat conductivity for this purpose.

Description

Die Erfindung betrifft ein Verfahren zur Raumklimatisierung mittels einer Klimadecke aus von der Raumdecke beabstandet angeordneten Akustikplatten, die aus einem luftdurchlässigen Werkstoff bestehen, der mit einer porösen Abdeckung versehen ist.The invention relates to a method for room air conditioning spaced from the ceiling by means of a climate ceiling arranged acoustic panels made of an air-permeable Made of material with a porous cover is provided.

Aus der Patentanmeldung EP 0 756 138 A2 ist ein flächiges Kühl- und Heizelement bekannt, das zur Ausbildung einer Klimadecke dient, wobei oberhalb der Klimadecke ein Teilstrom der Zuluft erzeugt wird und durch die porösen Akustikplatten der Klimadecke hindurch in den Raum darunter gelangt. Ein weiterer Teilstrom wird aus der Außenluft angesaugt und durch eine Raumwand direkt in den Raum eingeblasen. Es ist deshalb nicht erforderlich, den Hohlraum über der Klimadecke gegenüber dem Raum darunter hermetisch abzudichten, zumal auch der Teilstrom durch die Klimadecke hindurch von einem weiteren Teilstrom ergänzt werden kann, der durch eine größere Öffnung in der Klimadecke ohne wesentlichen Druckabfall in den Raum gelangt. Die Temperie rung des Raumes erfolgt im wesentlichen durch Konvektion und erfordert einen beträchtlichen Steueraufwand.From the patent application EP 0 756 138 A2 is a flat Cooling and heating element known to form a Climatic ceiling serves, with a partial flow above the climate ceiling the supply air is generated and by the porous acoustic panels through the climate ceiling into the room below arrives. Another partial flow is drawn in from the outside air and blown directly into the room through a wall. It is therefore not necessary to use the cavity hermetically above the climatic ceiling opposite the room below to seal, especially since the partial flow through the climate ceiling can be supplemented by a further partial flow, the through a larger opening in the climate ceiling without essential Pressure drop enters the room. The temperament The room is essentially operated by convection and requires considerable tax expense.

Aus der Patentanmeldung NL 8502079 A ist auch bereits eine geschlossene, in einen Raum eingehängte Zwischendecke bekannt, die einen an der Raumdecke angesiedelten Hohlraum abteilt, über den die Zuluftzufuhr durch die Zwischendecke hindurch erfolgt, während die Abluft aus dem Raum durch Auslässe in dem Raumboden abgesaugt wird. Eine Temperierung des Raumes ist hierbei aber nicht vorgesehen, und die Zwischendecke besteht auch nicht aus lärm- und wärmedämmend wirkenden Akustikplatten, so daß die Nachrüstung mit einem Wärmetauscher nicht zu einer befriedigenden Raumtemperierung und -schalldämmung führen kann.From patent application NL 8502079 A there is already one closed suspended ceiling known in a room known the one cavity located on the ceiling compartment through which the supply air supply through the false ceiling takes place while the exhaust air from the room is through Outlets in the room floor is suctioned off. A tempering the space is not provided here, and the false ceiling also does not consist of noise and heat insulation acting acoustic panels, so that the retrofit with a Heat exchanger not to a satisfactory room temperature and sound insulation.

Aus der US-A-4487794 ist eine poröse Aktustikplatte aus Metall, z.B. aus Edelstahl mit einer porösen Abdeckung aus Metall, z.B. Aluminium bekannt. Aufgrund seiner porösen Eigenschaften wäre diese bekannte Produkt zur Anwendung bei einer Klimadecke geeignet. Allerdings eignet sich dieses Material, da es sich um ein schallhartes Material handelt, für Klimadecken nur dann, wenn auf die akustischen Eigenschaften dieser Decken wenig Wert gelegt wird.From US-A-4487794 is a porous acoustic panel made of metal, e.g. made of stainless steel with a porous cover Metal, e.g. Known aluminum. Because of its porous properties would be to apply this well-known product suitable for a climate ceiling. However, this is suitable Material because it's a reverberant material, for climatic ceilings only if the acoustic properties little value is placed on these blankets.

Die Erfindung hat sich deshalb die Aufgabe gestellt, eine Verfahren zur Raumklimatisierung mittels einer Klimadecke so auszubilden, daß sie mit geringem Aufwand für die Steuerung und Regelung erfolgen kann und dabei aber trotzdem ein angenehmes, zugfreies Raumklima schafft und dabei die Vorteile einer schall- und wärmedämmenden Ausführung beibehält.The invention has therefore set itself the task Process for air conditioning by means of a climate ceiling to be trained so that they can be operated with little effort and regulation can take place and still a creates a pleasant, draft-free indoor climate and the advantages maintains a sound and heat insulating version.

Ausgehend vom Oberbegriff des Anspruchs 1 wird die Aufgabe dadurch gelöst, daß die Akustikplatten so angeordnet werden, daß zwischen der Klimadecke und der Raumdecke ein Hohlraum ausgebildet wird, der mit dem Raum durch die Klimadecke strömungsverbunden und im übrigen zu dem Raum hin abgedichtet ist, daß dem Raum die Zuluft vollständig oder zumindest überwiegend über die Klimadecke zugeführt wird, daß weiterhin der Hohlraum mit temperierter Druckluft beaufschlagt und deren Druck so gewählt wird, daß durch die Akustikplatten zum Raum hin eine laminare Luftströmung ohne eine in dem Raum auftretende Zugerscheinung erzeugt wird, daß ferner der Werkstoff der Akustikplatte und ihrer Abdeckung so gewählt werden, daß der Anteil der Wärmestrahlung an dem Wärmetransport in den Raum zwischen 20 und 80 % betragen, so daß ein Teil des über die Akustikplatte verlaufenden Wärmetransportes in den Raum als Wärmestrahlung erfolgt, und daß schließlich die Abluft aus einem von der Klimadecke beabstandeten und/oder gegen die von dieser ausgehenden Wärmestrahlung abgeschotteten Raumbereich abgeführt wird.Starting from the preamble of claim 1, the object is achieved in that the Acoustic panels should be arranged so that between the climate ceiling and a cavity is formed in the ceiling, which is fluidly connected to the room through the climate ceiling and otherwise sealed to the room that the Clear the supply air completely or at least predominantly the climatic ceiling is fed in that the cavity continues pressurized with compressed air and their pressure like this is chosen that through the acoustic panels to the room a laminar flow of air without one occurring in the room Drafts are generated that the material the acoustic panel and its cover are chosen so that the proportion of heat radiation in the heat transport in the space between 20 and 80%, so that a Part of the heat transfer via the acoustic panel takes place in the room as heat radiation, and that finally the exhaust air from a room that is spaced from the climate ceiling and / or against those emanating from it Thermal radiation is removed from the partitioned area.

Bei einem auf diese Weise klimatisierten Raum besteht nicht die Gefahr, daß durch direkt eingeleitete Außenluft Zugerscheinungen oder eine Taupunkt-Unterschreitung eintreten; andererseits kann eine von der Wärmestrahlung abgeschirmte Abführung der Raumluft für einen steten Luftwechsel ohne wesentliche Wärmeverluste sorgen. Ganz wesentlich ist es, daß die Zuluft vor ihrem Eintritt in den Raum in Wärmeaustausch mit den Akustikplatten tritt, so daß diese eine Wärmestrahlung abgeben und der Raum in kurzer Zeit temperierbar ist.A room that is air-conditioned in this way does not exist the risk of drafts from directly introduced outside air or a drop below the dew point; on the other hand, one that is shielded from heat radiation Exhaustion of the room air for a constant air change without cause significant heat losses. It is very important that the supply air exchanges heat before entering the room occurs with the acoustic panels, so that this is heat radiation deliver and the room can be tempered in a short time is.

Es ist zweckmäßig, wenn der Druck der Druckluft und die Akustikplatten so gewählt werden, daß zwischen dem Hohlraum und dem Raum eine Druckdifferenz von höchstens 20 Pa auftritt. Damit ist gewährleistet, daß einesteils eine ausreichende Luftwechselzahl erreicht wird, ohne daß andererseits Zugerscheinungen auftreten, wobei Verwirbelungen unmittelbar an der Klimadecke vermieden werden können, wenn die laminare Luftströmung mit höchstens 0,1 m/s aus der Klimadecke austritt. In dem Raum selbst soll die Luftströmung 0,25 m/s nicht überschreiten.It is useful if the pressure of the compressed air and the Acoustic panels are chosen so that between the cavity and a pressure difference of at most 20 Pa occurs in the room. This ensures that one part is sufficient Air exchange rate is achieved without, on the other hand Drafts appear, with swirling immediately on the climatic ceiling can be avoided if the laminar Air flow with a maximum of 0.1 m / s from the climate ceiling exit. In the room itself, the air flow should Do not exceed 0.25 m / s.

Insgesamt erfüllt eine solche Klimadecke hohe Anforderungen an Behaglichkeit und Gesundheit in dem klimatisierten Raum bei geringen Anforderungen an den baulichen Aufwand und die Unterhaltung der Anlage, wozu besonders beiträgt, daß der Hohlraum frei von Einbauten ist und keine Taupunktunterschreitung durch Außenluftzufuhr zu befürchten ist. Das Verfahren schafft eine Anordnung, bei der die Aufgaben einer Klimadecke und eines Luftsystems gleichzeitig wahrgenommen werden, so daß auch die Anfertigung und der Einbau außerordentlich wirtschaftlich erfolgen können.Overall, such a climate ceiling meets high requirements of comfort and health in the air-conditioned room with low demands on the structural effort and the Maintenance of the system, to which the The cavity is free of internals and is not below the dew point from outside air supply is to be feared. The Procedure creates an arrangement in which the tasks of a Climate ceiling and an air system perceived at the same time be, so that the preparation and installation can be done extremely economically.

Die Erfindung wird nachstehend an Hand der Zeichnung an einem Ausführungsbeispiel näher erläutert. Die einzige Figur zeigt einen schematischen Schnitt durch einen Raum mit einer nach dem erfindungsgemäßen Verfahren arbeitenden Klimatisierung.The invention is described below with the aid of a drawing Embodiment explained in more detail. The only figure shows a schematic section through a room with a Air conditioning working according to the inventive method.

In einen zu klimatisierenden Raum 1 ist mit Abstand zu seiner Raumdecke 2 eine Klimadecke 3 in geeigneter fachüblicher, hier nicht näher angedeuteter Weise eingehängt. Die Klimadecke 3 besteht aus einzelnen, porösen Akustikplatten 4, die mit schmalen und abgedichteten Stoßfugen 5 aneinander und an den umgebenden Raumwänden 6 liegen. Zumindest auf ihren dem Raum 1 zugewandten Seiten sind die Akustikplatten 4 jeweils mit einer Abdeckung 7 belegt, die ebenfalls porös ausgebildet ist, so daß Schallwellen in die Akustikplatten 4 eindringen und hier absorbiert werden können. Zwischen der Klimadecke 3 und der Raumdecke 2 ist demzufolge ein Hohlraum 8 gebildet und von dem Raum 1 relativ hermetisch abgeteilt. In a room 1 to be air-conditioned is at a distance from it Ceiling 2 a climate ceiling 3 in a suitable, customary, not shown here. The Climate ceiling 3 consists of individual, porous acoustic panels 4, with narrow and sealed butt joints 5 to each other and lie on the surrounding room walls 6. At least on their sides facing room 1 are the acoustic panels 4 each covered with a cover 7, which also is porous, so that sound waves in the Acoustic panels 4 penetrate and can be absorbed here. There is therefore between the air conditioning ceiling 3 and the ceiling 2 a cavity 8 is formed and relative to the space 1 hermetically partitioned.

An dem über einem Raumboden 9 aufgebauten Raum 1 mit seinen Raumwänden 6 sind symbolisch Öffnungen - je ein Fenster 11 und eine Tür 12 - angedeutet, die, auch in geschlossenem Zustand, zu einem Luftwechsel des Raumes 1 herangezogen werden können. Mindestens ein Durchlaß 13 für die Abluft 14 kann darüberhinaus vorgesehen sein in einer weiter unten beschriebenen speziellen Anordnung.On the room 1 built over a room floor 9 with his Room walls 6 are symbolically openings - each a window 11 and a door 12 - indicated, which, even when closed Condition, used for an air change in room 1 can be. At least one passage 13 for the exhaust air 14 can also be provided in a further below described special arrangement.

Der Hohlraum 8 steht über mindestens einen Durchlaß 15 mit einer Druckluftquelle in Verbindung, die für die Bereitstellung der erforderlichen Zuluft 16 sorgt, welche durch die Akustikplatten 4 und deren Abdeckung 7 als homogene laminare Luftströmung 17 in den Raum 1 gespült wird. Die Druckdifferenz über die Klimadecke 3 - maximal 20 Pa - wird so gewählt, daß die Luftströmung 17 mit höchstens 0,1 m/s aus den Abdeckungen 7 austritt.The cavity 8 is provided with at least one passage 15 a compressed air source connected for deployment the necessary supply air 16, which ensures the acoustic panels 4 and their cover 7 as homogeneous laminar Air flow 17 is flushed into room 1. The Pressure difference across the air conditioning ceiling 3 - maximum 20 Pa chosen so that the air flow 17 at a maximum of 0.1 m / s emerges from the covers 7.

Die mit der Luftströmung 17 verbundene Wärmeströmung bleibt nur teilweise an die Luftströmung 17 gekoppelt. Wegen der speziellen Ausführung der Akustikplatten 4 und deren Abdeckung 7 jeweils aus einem Werkstoff hoher Wärmeleitfähigkeit wird ein Teil der Wärmeströmung aus der Luftströmung ausgeschieden und über die Akustikplatten 4 und deren Abdeckungen 7 teilweise durch Wärmeübergang, zumeist aber durch (trägheitslose) Wärmestrahlung an den Raum 1 abgegeben, der auf diese Weise rasch temperierbar ist. Der Durchlaß 13 für die Abluft 14 ist deshalb weit entfernt von der Klimadecke 3 angelegt; gegebenenfalls ist der den Durchlaß 13 enthaltende Raumbereich 10 gegen die aus der Klimadecke 3 austretende Wärmestrahlung abgeschirmt. The heat flow associated with the air flow 17 remains only partially coupled to the air flow 17. Because of the special version of the acoustic panels 4 and their Cover 7 each made of a material with high thermal conductivity becomes part of the heat flow from the air flow excreted and on the acoustic panels 4 and their Covers 7 partly through heat transfer, but mostly emitted to room 1 by (inertia) heat radiation, which can be quickly tempered in this way. The passage 13 for the exhaust air 14 is therefore far from the Climate cover 3 created; if necessary, this is the culvert 13 containing room area 10 against that from the climate ceiling 3 escaping heat radiation shielded.
