Abstract

The ventilation device which may be fitted around the inside of a window frame, allows the inlet and outlet air flows to travel in counterflow through the interior giving both a heat and humidity interchange. The two channels for the two flows are separated by a sheet (1) across the middle, leaving a small gap for condensation. This dividing sheet forms two chambers inside a perforated sheet (2) enclosed by a felt material (3) with sealing foil which absorbs the moisture. These layers are enclosed in a sound deadening layer (4) enclosed by an outer casing (5). The whole is compact and unobtrusive and can form a frame around the window.

BESCHREIBUNGDESCRIPTION

Die Erfindung betrifft dezentrale Lüftungs-Wärmetauscher-Systeme, zur energiesparenden Raumlüftung, die in Normal- oder Lärmschutzfenster eingebaut bzw. integriert werden können.The invention relates to decentralized ventilation heat exchanger systems, for energy-saving room ventilation that can be installed or integrated in normal or noise-proof windows.

Diese Lüftungs-Wärmetauscher -Systeme bezwecken, die durch gesetzliche Verordnungen (Energieeinsparungsgesetz) und aus schallschutztechnischen Gründen erforderliche Fugendichtigkeit und damit Luftundurchlässigkeit der Fenster durch energiesparende Lüftungssysteme auszugleichen und damit deren Funktionsfähigkeit wiederherzustellen.The purpose of these ventilation heat exchanger systems is to comply with statutory regulations Ordinances (Energy Saving Act) and, for reasons of soundproofing, required joint tightness and thus airtightness to compensate the windows with energy-saving ventilation systems and thus restore their functionality.

Die bestehenden dezentralen (d.h. im Räume selbst angeordneten) Lüftungsanlagen sind aus energieökonomischer Sicht unbefriedigend, da diese in der Regel warme, feuchte und verbrauchte Luft abführen und kalte, trocknerere Frischluft zuführen. Dabei geht die Wärme und Feuchtigkeit der Abluft verloren und die Zuluft muß zusätzlich erwärmt und nachbefeuchtet werden.The existing decentralized (i.e. arranged in the room itself) Ventilation systems are unsatisfactory from an energy-economical point of view, as they usually dissipate warm, humid and stale air and supply cold, drier fresh air. The heat and moisture of the exhaust air is lost and the supply air has to be added be heated and re-moistened.

Aufgabe des Lüftungs-Wärmetauscher-Systems ist es, die in der Abluft eines Raumes enthaltene Wärme und Feuchtigkeit während der Heizperiode direkt auf die kalte Zuluft (im Sommer umgekehrt von der kühleren Abluft auf die wärmere Zuluft) zu übertragen, um dadurch die Lüftungswärmeverluste bei der Raumheizung und -kühlung erheblich zu reduzieren.The task of the ventilation heat exchanger system is to remove the air in the exhaust air heat and moisture contained in a room during the heating season directly on the cold supply air (in summer the opposite of the cooler exhaust air to the warmer supply air) in order to reduce the ventilation heat losses during room heating and cooling to reduce significantly.

Das wird durch das dezentrale Lüftungs-Wärmetauscher-System dadurch gelöst, daß die Zu- und Abluftströme in Kanälen gegenläufig an Wärmetauscherbleche aus gut wärmeleitendem Material vorbeigeführt werden, über die ein direkter Wärme- und Feuchtigkeitsaustausch erfolgen kann.This is made possible by the decentralized ventilation heat exchanger system solved that the incoming and outgoing air flows in channels in opposite directions past heat exchanger plates made of a material that conducts heat well through which a direct heat and moisture exchange can take place.

Die Vorteile des dezentralen, in das Fenster integrierten Lüftungs-Wärmetauscher-Systems liegen darin, daß gegenüber der natürlichen Lüftung durch öffnen der Fenster oder durch Fugenundichtigkeiten sowie gegenüber der künstlichen Lüftung durch getrennte Zu- und Abluftanlagen ein erheblicher Teil (50 bis 70 %) der Lüftungswärmeverluste eingespart werden können.The advantages of the decentralized ventilation heat exchanger system integrated into the window are that, compared to natural ventilation by opening the window or due to leakage in the joints, and compared to artificial ventilation by separate supply and exhaust air systems, a considerable part (50 to 70 %) of the Ventilation heat losses can be saved.

ANLAGE 2 -2-APPENDIX 2 -2-

Im Gegensatz zu konventionellen Lüftungsanlagen ist das Lüftungs-Wärmetauscher-System in der Regel infolge der thermischen Auftriebskräfte auch ohne mechanische Hilfe voll funktionsfähig. Wegen der guten schalldämpfenden Eigenschaften ist die vorgeschlagene Lösung besonders für den Einbau in Lärmschutzfenster für alle Lärmschutzklassen geeignet.In contrast to conventional ventilation systems, the ventilation heat exchanger system usually fully functional even without mechanical help due to the thermal buoyancy forces. Because of the good sound-absorbing properties, the proposed solution is particularly suitable for installation in soundproof windows suitable for all noise protection classes.

In Figur 1 ist die Zu- und Abluftführung während der Heizperiode anhand eines Funktionsschemas dargestellt.In Figure 1, the supply and exhaust air flow during the heating period is shown using a functional diagram.

Figur 2 und 3 stellen Ausführungsbeispiele für Zwei- und Mehrkammersysteme dar: /-,\Figures 2 and 3 represent embodiments for two- and multi-chamber systems dar: / -, \

Das mittlere, geschlossene Wärmeleitblech trennt die gegenläufigen Zu- und Abluftströme luftmäßig, läßt jedoch in bestimmten Abständen an den Überlappungsstellen der Bleche die Kondensatfeuchtigkeit durch die so gebildete Haarfuge auf die Gegenseite übertreten. Das äußere Wärmeleitblech (2) ist gelocht, mit einem Saugvlies (3) und einer Dichtungsfolie umgeben, sodaß auch hier die Wärme und das Kondensat durch die Kapillarwirkung des Vlieses auf die Gegenseite übertragen wird und dort abgegeben werden kann.The middle, closed heat conducting plate separates the opposing ones Incoming and outgoing air streams air-wise, but leaves the condensate moisture at certain intervals at the overlapping points of the sheets step over to the opposite side through the hairline joint formed in this way. The outer heat conducting plate (2) is perforated with a suction fleece (3) and surrounded by a sealing film, so that here too the heat and condensate due to the capillary effect of the fleece on the opposite side is transferred and can be handed in there.

Das Lochblech (2) hat in Verbindung mit dem Saugvlies (3) und der Dämmschicht auch noch die Funktion eines Schalldämpfers. Je nach Erfordernis kann durch Zwei- oder Mehrkammersysteme und unterschiedliche Schicht- und Kanalstärken dem Wärmeaustausch oder dem Schallschutz bevorzugt Rechnung getragen werden.The perforated plate (2), in conjunction with the absorbent fleece (3) and the insulation layer, also has the function of a silencer. Depending on Two- or multi-chamber systems and different layer and channel thicknesses can be required for heat exchange or sound insulation preferred to be taken into account.

Das Lüftungs-Wärmetauscher-System kann in alle herkömmlichen Fensterarten aus Holz, Metall oder Kunststoff eingebaut oder direkt in die Fensterkonstruktion (Kastenfenster) integriert werden. Es erfordert einen vergleichsweise geringen seitlichen Platzbedarf von je 2 bis 3 cm zusätzlich, sodaß das äußere und innere Erscheinungsbild des Fensters nicht beeinträchtig wird. Kann bei der Altbauerneuerung der alte Fensterstock belassen werden, wird die lichte Fenstergröße überhaupt nicht beeintächtigt, da das Lüftungs-Wärmetauscher-System im alten Stockbereich untergebracht werden kann.The ventilation heat exchanger system can be installed in all conventional window types made of wood, metal or plastic or integrated directly into the window construction (box window). It requires a comparatively small side space requirement of 2 to 3 cm each, so that the external and internal appearance of the Window is not affected. If the old window frame can be left when renovating the old building, the clear window size will be Not at all bothered, as the ventilation heat exchanger system can be accommodated in the old floor area.
