Abstract

In order that the hot-air underfloor heating responds more quickly and the required change of air can be kept to a minimum, a portative air-permeable layer (3) is provided in the floor of the living space and above this layer a subfloor (4). In the layer (3), there is embedded close to one wall (5) a hot-air distribution channel (6). The opposite wall (8) has air gaps (9) so that the hot air from the distribution channel (6) travels through the layer (3) to these air gaps (9), where it flows out into the living space. In the wall (5) close to the distribution channel (6), air draw-off channels (10) are provided above the subfloor (4). <IMAGE>

Description

Die Erfindung betrifft eine Warmluftbodenheizung, mit Kanälen für die Warmluftzufuhr sowie für die Absaugung der Raumluft, und mit einer Wärmeisolationsschicht über der Betondecke.The invention relates to a warm air underfloor heating, with channels for the supply of warm air and for the extraction of the room air, and with a heat insulation layer over the concrete ceiling.

In der CH-PS 487.376 ist ein Verfahren zur Temperaturbeeinflussung von Räumen mit Luft beschrieben, bei welchem ein Teil der Luft im Kreislauf zirkuliert, wobei der Förderweg der Luft über die gesamte Fläche der Dek- ken"Wände und Böden der Räume sich erstreckende Kanäle verläuft.CH-PS 487.376 describes a method for influencing the temperature of rooms with air, in which part of the air circulates, the air conveying path running through the entire surface of the ceiling, walls and floors of the rooms .

Die US-PS 4,051,999 betrifft ein Gebäude mit Lufterwärmung im Dachgeschoss durch Sonneneinstrahlung. Die Luft strömt vom Dach nach unten durch einen Ventilator zu einem Wärmespeicher, der sich unter den ganzen Fussboden erstreckt. Die zur Heizung oder Kühlung des Hauses konditionierte Luft wird durch Klappen gesteuert.The US-PS 4,051,999 relates to a building with air heating in the attic by solar radiation. The air flows down from the roof through a fan to a heat accumulator that extends under the entire floor. The air conditioned for heating or cooling the house is controlled by flaps.

Die CH-PS 626.716 zeigt einen Flächen-Wärmeaustauscher. Dieser besteht aus profilierten Blechen mit Rippen, in welchen, je nach Verwendungszweck, auch Rohre angeordnet sind. Anwendungs gebiete sind: Fussboden-Heizungen mit Luft und/oder Flüssigkeit als Wärmeträger; als Wand-Heizkörper und als Solarkollektor für Dächer, Fassaden oder begehbare Flächen.CH-PS 626.716 shows a surface heat exchanger. This consists of profiled sheets with ribs, in which, depending on the intended use, tubes are arranged. Areas of application are: underfloor heating with air and / or liquid as a heat carrier; as a wall-mounted radiator and as a solar collector for roofs, facades or accessible surfaces.

In der OS-DE 31.09.419 Al ist eine Heissluftanordnung bekanntgegeben, die mit Warmluft arbeitet und einen Lufterhitzer sowie Warmluft- und Abluftkanäle mit Ventilatoren und Filtern aufweist, wobei die Warmluftkanäle die Warmluft zu einem Warmluftverteilerkanal leiten, der in der Ebene der Fussbodenkonstruktion eines zu beheizenden Raumes angeordnet ist und Oeffnungen für den Austritt der Warmluft aufweist, wobei im Fussboden Oeffnungen vorgesehen sind, aus denen Warmluft in den zu beheizenden Raum geleitet wird, und wobei auf Abstandhaltern, die auf einer Wärmeisolationsschicht einer Deckenunterkonstruktion angeordnet sind, eine Trockenestrichkonstruktion ruht und aus den Oeffnungen des Warmluftverteilerkanals die Luft frei in den Hohlraum, der sich unterhalb der Trockenestrichkonstruktion und oberhalb der Isolationsschicht befindet, einströmt.In OS-DE 31.09.419 Al a hot air arrangement is announced which works with warm air and an air heater as well as warm air and exhaust air ducts with Ven tilators and filters, the warm air ducts direct the warm air to a warm air distribution duct which is arranged in the level of the floor construction of a room to be heated and has openings for the escape of warm air, openings being provided in the floor from which warm air is to be heated Space is directed, and where a dry screed construction rests on spacers, which are arranged on a thermal insulation layer of a ceiling substructure, and the air flows freely from the openings of the warm air distribution duct into the cavity, which is located below the dry screed construction and above the insulation layer.

Die FR-PS 2.514.868 bezieht sich auf einen auf einem Wärmespeicher liegenden Fussboden, wobei Luft als Wärmeträger in einem geschlossenen Kreislauf vom Wärmespeicher zu den Luftkanälen im Fussboden geführt wird. Als Heizenergie dient Sonnenwärme. Die erwärmte Luft wird 'im Kreislauf von einem Ventilator vom Dach durch den Wärmespeicher geblasen. Der Wärmespeicher kann kiesigen Sand oder Betonelemente enthalten.FR-PS 2.514.868 relates to a floor lying on a heat store, air being conducted as a heat carrier in a closed circuit from the heat store to the air channels in the floor. Solar heat is used as heating energy. The heated air is blown in a circuit by a fan from the roof through the heat accumulator. The heat accumulator can contain gravelly sand or concrete elements.

Der Nachteil der üblichen Warmluftheizungen besteht darin, dass die Warmluft relativ warm eingeblasen werden muss und dadurch ein Temperaturgefälle im Raum entsteht (oben warm - unten kalt) während der Fussboden kühl bleibt.The disadvantage of the usual warm air heating is that the warm air has to be blown in relatively warm and this creates a temperature gradient in the room (warm above - cold below) while the floor remains cool.

Bei der Erfindung wird ein Teil-der Wärmeenergie vom gesamten Fussboden abgegeben, dadurch wird der Fussboden leicht temperiert und die eingeblasene Zuluft relativ kühler.In the invention, a part of the thermal energy is given off from the entire floor, as a result of which the floor is heated slightly and the incoming air blown in relatively cooler.

Vorliegender Erfindung liegt nun die Aufgabe zugrunde, eine Warmluftbodenheizung zu schaffen, die rascher reagiert, d.h. dass die Wärmekapazität des Wärmespeichers den Anforderungen besser angepasst ist, dass die Luftzirkulation einen minimalen Luftwechsel gestattet, und wobei eine relativ einfache, kostengünstige Konstruktion angestrebt wird.The present invention is based on the object of creating a warm air underfloor heating which responds more quickly, i.e. that the heat capacity of the heat accumulator is better adapted to the requirements, that the air circulation permits minimal air exchange, and that a relatively simple, inexpensive construction is sought.

Die erfindungsgemässe Warmluftunterbodenheizung ist dadurch gekennzeichnet, dass sie eine tragfähige, luftdurchlässige Schicht mit einem Warmluftverteilerkanal und darauf einen Unterlagsboden besitzt und dass auf der dem Warmluftverteilerkanal gegenüberliegende Seite des Unterlagsbodens, längs der Wand, wenigstens ein Luftaustrittsschlitz vorgesehen ist.The hot air underfloor heating according to the invention is characterized in that it has a load-bearing, air-permeable layer with a warm air distribution channel and a sub-floor thereon and that at least one air outlet slot is provided on the side of the sub-floor opposite the warm air distribution channel, along the wall.

In der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes dargestellt. Es zeigen:

  • Fig. 1 einen Vertikalschnitt nach Linie I-I der Fig. 2 einer Warmluftbodenheizung, und
  • Fig. 2 einen Grundriss zu Fig. 1.
In the drawing, an embodiment of the subject of the invention is shown. Show it:
  • Fig. 1 is a vertical section along line II of Fig. 2 of a warm air floor heating, and
  • 2 is a plan view of FIG. 1st

Bei der dargestellten Warmluftbodenheizung weist der Boden des Wohnraumes unten eine Betonschicht 1, darüber eine Wärmeisolationsschicht 2 und über dieser eine tragfähige, luftdurchlässige Schicht 3 auf, welche durch einen Unterlagsboden 4 zugedeckt ist (Fig. 1).In the warm air floor heating system shown, the floor of the living room has a concrete layer 1 below, a heat insulation layer 2 above and a load-bearing, air-permeable layer 3, which is covered by a sub-floor 4 (FIG. 1).

In der Schicht 3 ist, nahe einer Wand 5, ein Wärmeluftverteilerkanal 6 eingebettet, der mit einem Warmluftzufuhrkanal 7 verbunden ist. An der gegenüberliegenden Wand 8 sind zwei Warmluftaustrittschlitze 9 vorgesehen (Fig. 1 und 2), so dass die Warmluft vom Verteilerkanal 6 durch die Schicht 3 zu den Schlitzen 9 gelangt, aus denen sie in den Wohnraum strömt. Die dem Verteilerkanal 6 naheliegende Wand 5 weist zwei Luftabsaugkanäle 10 auf.In the layer 3, near a wall 5, a heat air distribution duct 6 is embedded, which is connected to a warm air supply duct 7. On the opposite wall 8 there are two hot air outlet slots 9 seen (Fig. 1 and 2), so that the warm air from the distribution channel 6 passes through the layer 3 to the slots 9, from which it flows into the living room. The wall 5 close to the distribution channel 6 has two air extraction channels 10.

Die Schicht 3 kann aus Tonkugeln, Granulat, grobem Kies, profilierten Kunststoffbahnen oder Kunststoffbahnen mit Noppen bestehen.Layer 3 can consist of clay balls, granules, coarse gravel, profiled plastic sheets or plastic sheets with knobs.

Eine den Anforderungen angepasste Höhe der Schicht 3 und die relativ einfache Luftführung bewirken, dass die Warmluftbodenheizung rasch reagiert, wobei auch nur ein zweifacher statt ein fünffacher Luftwechsel pro Stunde erforderlich ist.A height of layer 3 adapted to the requirements and the relatively simple air flow ensure that the warm air underfloor heating reacts quickly, with only two instead of five air changes per hour being required.

Bei der beschriebenen Warmluftbodenheizung wird der Fussboden leicht temperiert und ein Teil der Wärmeenergie vom gesamten Fussboden abgegeben. Die eingeblasene Zuluft ist relativ kühler als bei den üblichen Warmluftheizungen, bei welchen die Luft relativ warm eingebla- sen werden muss und dadurch ein Temperaturgefälle im Raum verursacht (oben warm, unten kalt), während der Fussboden kühl bleibt.In the hot air floor heating system described, the floor is heated slightly and part of the thermal energy is emitted from the entire floor. The injected supply air is relatively cooler than with conventional warm air heating systems, in which the air must be blown in relatively warm, causing a temperature gradient in the room (warm at the top, cold at the bottom), while the floor remains cool.
