Abstract

In order, in the case of exterior walls of heated and ventilated rooms, to recover not only the transmission heat, but also the ventilation heat, a ventilated facade is fastened in front of the house wall. A sheet separating the supply-airstream and discharge-airstream is located centrally in this air gap. Along this sheet, the discharged air transmits its heat to the supply air. In order that the heated supply air is not considerably cooled by the facade, the latter is heat-insulated. In order, however, to be able to make optimum use of the facade as a solar absorber, the actual facade is mounted such that it is separated from the insulating wall by an air gap. Before the supply air reaches the sheet, it flows through this air gap and absorbs the solar heat from the facade. The supply-airstream and discharge-airstream are produced in each case by a ventilator in the wall. In order that the wind pressure does not ventilate (cool down) the house in an uncontrolled manner when the ventilator is not in use, a double flap seals off both air ducts when the ventilator is not operating. The wind pressure does not produce any actuating force on the double flap.

In der Patentschrift 20 38 510, Aktenzeichen P 20 38 510.8-25 mit Ausgabetag vom 17.2.77jder Europäischen Patentanmeldung, Veröffentlichungsnummer 0131 £44, Anmeldetag 15.7.83 und der Patentanmeldung am "Deutschen Patentamt" vom 2.8.1985, Aktenzeichen P 3530 884.2, wird ein Verfahren beschrieben, wie bei einer Hauswand durch Anbringung einer Fassade die Transmissionswärme der Wand größtenteils zurückgenommen wird (Anspruch 1).In patent specification 20 38 510, file number P 20 38 510.8-25 with an issue date of February 17, 1977 of the European Patent application, publication number 0131 £ 44, Filing date 07/15/83 and the patent application at the "German Patent Office" dated 02/08/1985, file number P 3530 884.2 a procedure described as with a house wall through Attaching a facade to the transmission heat of the wall is largely withdrawn (claim 1).

Ferner soll ein Teil der Sonneneinstrahlung durch Erwärmung der Fassade genutzt werden (Anspruch 2). .Furthermore, some of the solar radiation should be caused by warming the facade can be used (claim 2). .

Dieses Verfahren hat 4 wesentliche NachteilesThis method has 4 major drawbacks

1. Die Wärme derjenigen Raumluftmenge, die durch Einblasen der warmen Zuluft zwangsweise aus dem Haus geblasen wird., kann nicht direkt durch rekuperative Wärmerückgewinnung über Wärmetauscher genutzt werden. Nur über eine Wärmepumpe im Keller ist diese Wärme zum kleinen Teil zu nutzen.1. The heat of that amount of room air that is blown in the warm supply air is forcibly blown out of the house., cannot directly through recuperative heat recovery can be used via heat exchangers. This heat is only available to a small extent via a heat pump in the basement to use.

2. Bei der Erwärmung der Zuluft durch die Transmissionswärme geht davon ein erheblicher Teil durch die Fassade an die Außenluft verloren, weil die Fassade zum Zwecke der Solarwärme-Nutzung eine gute Wärmeleitung haben muß.2. When the supply air is heated by the transmitted heat a considerable part of this is lost through the facade to the outside air, because the facade becomes For the purpose of solar heat use, good heat conduction must have.

3. Um die Rückgewinnung der Transmissionswärme nicht stark zu reduzieren, wird die Fassade gut wärmedämmend ausgeführt. Das verhindert aber eine gute Nutzung der Solarwärme, da diese die Fassadenoberfläche relativ stark erwärmen muß (dadurch starke Wärmeabgabe an die Außenluft), damit die Wärme an die hintere Fassaden-Oberfläche fließen kann, um die Zuluft zu erwärmen. Eine sehr gut wärmeleitende Fassade (z.B. Kupferblech) kann nicht errichtet werden.3. To the recovery of the transmission heat not strong to reduce, the facade is made with good thermal insulation. However, this prevents good use of the Solar heat, as this makes the facade surface relatively strong has to warm up (thereby giving off a lot of heat to the outside air) so that the heat is transferred to the rear facade surface can flow to heat the supply air. A facade that conducts heat very well (e.g. copper sheet) can not be erected.

4. Bei abgestelltem Ventilator bläst der Winddruck auf der Luv-Seite des Hauses z.B. auch im Winter die ganze Nacht hindurch kalte Zuluft in die Wohnung, die dann in den Räumen auf der Wind-Lee-Seite durch die Kanäle in der Wand wieder ins Freie strömt.4. When the fan is switched off, the wind pressure blows on the Windward side of the house, e.g. cold supply air into the apartment all night long, even in winter, which then flows into the Vacate on the wind-leeward side through the channels in the Wall flows back into the open.

1.3 Verbesserung des technischen Standes.1.3 Improvement of the technical standard.

1.3. 1 Verbesserung zu Nachteil nach Abschnitt 1.2 Pkt.l.1.3. 1 Improvement to disadvantage according to Section 1.2 Pkt.l.

Eine übliche Hauswand bekommt eine Fassade vorgesetzt, die in einem bestimmten Abstand an die Außenwand aufgesetzt wird.A normal house wall is given a facade, which are placed on the outer wall at a certain distance will.

In der Mitte zwischen vorgesetzter Fassade und eigentlicher Hauswand wird eine dünne Folie gespannt (Abbildung 1 ). Ein Ventilator bläst kalte Frischluft (Zuluft) in den Spalt zwischen Fassade und Folie. Diese kalte Luft streicht an der Folie entlang und nimmt Wärme aus der Folienoberfläche auf.A thin film is stretched in the middle between the front facade and the actual house wall (Figure 1 ). A fan blows cold fresh air (supply air) into the gap between the facade and the membrane. This cold air strokes along the foil and absorbs heat from the foil surface.

Die vorgewärmte Frischluft wandert durch einen Mauer-, durchbruch auf die Innenseite der Wand. Hier tritt sie unter einem Heizkörper (Konvektor) aus. Sie wird in einen Verteilerkasten unter den wandseitigen Teil des Heizkörpers geleitet. Hier erwärmt sich die Frischluft und tritt in den Raum ein.The preheated fresh air wanders through a wall, breakthrough on the inside of the wall. Here she kicks under a radiator (convector). She will turn into a Distribution box under the wall-side part of the radiator directed. This is where the fresh air heats up and enters the room.

Der vordere Tei1 des Heizkörpers dient der Beheizung des Raumes durch Erwärmung der Umluft.The front part of the radiator is used to heat the By heating the circulating air.

Die zugeführte Frischluftmenge ist regelbar und kann (je nach Raum) z.B. bei einem Wohnraum von einer Luftungsrate 0,5/h auf 5/h variiert werden.The amount of fresh air supplied is adjustable and can (depending depending on the room) e.g. in a living room, the ventilation rate can be varied from 0.5 / h to 5 / h.

Entsprechend der Frischluftmenge saugt der Fortluft-Ventilator die gleiche Menge verbrauchter Raumluft als Fort.luft durch die Wand ins Freie. Sie streicht an der Folie entlang und gibt über sie die Wärme an die einströmende Frischluft ab (rekuperativer Wärmerückgewinn aus der Raum—Fortluft).Depending on the amount of fresh air, the exhaust air fan sucks in the same amount of used room air as Exhaust air through the wall into the open air. She strokes the Along the foil and transfers the heat to the incoming fresh air via it (recuperative heat recovery from the room exhaust air).

Der Fortluft-Ventilator hat immer die gleiche Drehzahl wie der Zuluft-Ventilator, damit im Raum kein über- bzw. Unterdruck entstehen kann.The exhaust air fan always has the same speed like the supply air fan, so that there is no overflow or overflow in the room. Negative pressure can arise.

1.3.2 Verbesserung zu Nachteil nach Abschnitt 1.2, Pkt. 2.1.3.2 Improvement to disadvantage according to Section 1.2, Point 2.

Anstelle der Fassade befindet sich dort eine Wärme-Dämmwand (Abbildung 2). Die kalte Zuluft kann voll die Wärme über die Folie aus der Fortluft übernehmen und sich dabei erwärmen.Instead of the facade there is a thermal insulation wall (Figure 2). The cold supply air can fully absorb the heat take over the film from the exhaust air and thereby heat.

Durch die Warme-Dämmwand fließt nur ein sehr kleiner Teil der zurückgewonnenen Lüftungs- und Hauswand—Transmiss!ons-Wärme. Diese wird dann von der kühlen Luft zwischen Dämmwand und Fassade wieder zurückgeführt. Only a very small part flows through the thermal insulation wall the recovered ventilation and house wall - transmission heat. This is then returned by the cool air between the insulating wall and the facade.

1.3.3 Verbesserung zu Nachteil nach Abschnitt 1.2 Pkt. 3.1.3.3 Improvement to the disadvantage according to section 1.2, point 3.

Die Fassade kann bei der Ausführung mit Wärme- Dämmwand (Abbildung 2) die notwendig gute Wärmeleitung (z.B. Kupferfassade) erhalten. Die Solarstrahlung erwärmt das Kupferblech sofort (geringe Wärmespeicherung). Praktisch gleichseitig nimmt die hintere Oberfläche der Kupferfassade auch diese höhere Temperatur an. Dadurch kann die kühle Zuluft sofort die Solarwärme übernehmen und in die Wohnung tragen. Damit erwärmt sich die Fassade weniger, wodurch an ihrer Außenaberfläche auch geringere Wärmeverluste entstehen.The facade can be designed with a thermal insulation wall (Figure 2) obtain the necessary good heat conduction (e.g. copper facade). The solar radiation heats it up Copper sheet immediately (low heat storage). The rear surface of the Copper facade also shows this higher temperature. Through this the cool supply air can immediately take over the solar heat and carry it into the apartment. This heats up the facade less, which means that there are also fewer on their outer surface Heat losses occur.

1.3.4 Verbesserung zu Nachteil nach Abschnitt 1.2 Pkt. 4.1.3.4 Improvement to disadvantage according to section 1.2, point 4.

IffIff

An den Kanalenden wird eine gewichts-(feder-)bei astete Doppel klappe angebracht. Das Gewicht 'hat die Klappe bei abgestelltem Ventilator zugedrückt. Von der waagerechten Lage des Gewichts her erzeugt es jetzt das größte Schiießmoment.A weight (spring) tab is attached to the ends of the duct Double flap attached. The weight pressed the flap shut when the fan was switched off. From the horizontal Due to the position of the weight, it now generates the greatest shooting moment.

Beide Ventilatoren drücken die Doppelklappe auf, wobei das Gewicht in eine fast senkrechte Lage kommt und damit das Schließmoment sehr gering wird, was dem geringeren Luftdruck bei Durchströmung entspricht.Both fans push the double flap open, whereby the weight comes in an almost vertical position and thus the closing torque is very low, which is the lower Corresponds to the air pressure when the air flows through.

Bei einer Feder verhält sich das genau umgekehrt, was sehr negativ ist.In the case of a spring, this is exactly the opposite, which is very negative.

Selbstverständlich kann die Doppel klappe auch über einen Stellmotor betätigt werden, der mit den Ventilatoren synchron geregelt wird.Of course, the double flap can also have one Servomotor can be operated, which is controlled synchronously with the fans.

Der Winddruck ist nicht in der Lage die Doppel klappe zu öffnen, da er auf beide Flügel der Klappe wirkt und sich damit kein Drehmoment ergibt. Eine kleine Rückstellkraft kann die Klappe geschlossen halten.The wind pressure is not able to close the double flap open, because it acts on both wings of the flap and there is no torque. A small restoring force can keep the flap closed.

Wenn die Doppel klappe geschlossen ist, gibt der obere Flügel den hinteren Teil des Konvektors frei und die Raumluft kann hier zusätzlich durchströmen.When the double flap is closed, the upper wing releases the rear part of the convector and the Room air can also flow through here.
