Abstract

1. Radiator for space heating with convectors supplied from different energy sources. The upper convector (2) is operated by means of a heating medium of a higher temperature and the lower convector (1) is operated by means of a heating medium of a lower temperature. The convectors are equipped with heatconducting lamellae (3, 4) - arranged one after the other in flow direction - that divide an air duct into a number of continuously ascending open flues (14). The radiator is characterized by the fact that the lamellae (4) of the higher temperature convector are connected with the lamellae (3) of the lower temperature convector by means of heat insulating bridges (11) made of a material of minor heat conductivity, such that the open flues (14) are kept free.

Description

OBERBEGRIFFSUMMARY

Die Erfindung bezieht sich auf einen multivalenten Heizkörper zur Raumluftbeheizung mit aus verschiedenen Energiequellen durch Heizmedien verschieden hoher Temperaturstufen beaufschlagten Konvektoren, welche wärmeleitende Lamellen tragen, die, untereinanderliegend, den Luftschacht, in Strömungsrichtung gesehen, in viele, durchlaufend aufsteigende, unten und oben offene Züge unterteilen.The invention relates to a multivalent radiator for room air heating with convectors acted on from different energy sources by heating media at different temperature levels, which carry heat-conducting fins, which, lying one below the other, divide the air shaft, seen in the direction of flow, into many, continuously ascending, open at the top and bottom .

STAND DER TECHNIKSTATE OF THE ART

In den bekannten multivalenten Heizkörpern der vorbezeichneten Art wird der Gesamtwirkungsgrad durch das vorgeschaltete, z.B. aus Sonnenenergie betriebene Heizsystem nur in unbefriedigendem Maße verbessert.In the known multivalent radiators of the aforementioned type, the overall efficiency is determined by the upstream, e.g. Heating system operated from solar energy only improved to an unsatisfactory degree.

WESEN DER ERFINDUNGEssence of the Invention

Der Erfindung liegt die Erkenntnis zugrunde, daß der Unterstützungseffekt des mit Sonnenenergie betriebenen Heizsystems in den herkömmlichen multivalenten Heizkörpern in hohem Maße durch thermische Rückkopplungen, sei es durch Turbulenzen der Luftströmung oder durch Wärmeleitung vom Konvektorsystem höherer zum Konvektorsystem niederer Temperatur, beeinträchtigt wird.The invention is based on the finding that the support effect of the heating system operated with solar energy in the conventional multivalent radiators is largely impaired by thermal feedback, be it by turbulence of the air flow or by heat conduction from the convector system to the convector system at a lower temperature.

Ausgehend von dieser Erkenntnis sind in die Wärmeleitwege von dem oder den Konvektoren höherer Temperatur zu den Konvektoren niederer Temperatur Wärmedämmzonen eingeschaltet, und es sind die Lamellen der Konvektoren und die sie umschließende Wandung des Luftschachtes so angeordnet, daß sie getrennt aufsteigende glatte Züge bilden.Based on this knowledge, the heat conduction path from the convector or convectors to the higher temperature Low-temperature convectors thermal insulation zones switched on, and the lamellae of the convectors and the wall of the duct surrounding them are arranged in such a way that they form separately ascending smooth trains.

Durch die Lamellen der Heizkörper wird bei dieser Gestaltung eine ungestörte laminare Strömung der zu erwärmenden Luft erzwungen, und es wird gleichzeitig durch die Wärmedämmzonen eine thermische Rückkopplung über metallische Verbindungen im System vermieden, so daß sich ein multivalentes Heizsystem mit praktisch rückuirkungsfreiem Wärmeaustausch in mehreren, räumlich und thermisch übereinanderliegenden Stufen ergibt.With this design, the fins of the radiators force an undisturbed laminar flow of the air to be heated, and at the same time thermal feedback via metallic connections in the system is avoided through the thermal insulation zones, so that a multivalent heating system with practically non-reactive heat exchange in several, spatially and thermally superimposed stages.

Weitere Merkmale der Erfindung sind den Unteransprüchen und der folgenden Beispielsbeschreibung zu entnehmen.Further features of the invention can be found in the subclaims and the following example description.

Die in der Zeichnung dargestellten Beispiele eines multivalenten Heizkörpers dienen zur Raumluftbeheizung mit aus verschiedenen Energiequellen beaufschlagten Konvektoren, einem unteren Konvektor 1/3 und einem oberen Konvektor 2/4. Die Konvektoren 1/3 und 2/4 sind in einem gemeinsamen, unten und oben offenen Luftschacht 5 angeordnet. Sie uerden durch Heizmedien M1 und M2 aus verschiedenen Heizquellen betrieben, der obere Konvektor 2 aus einer herkömmlichen Heizquelle, z.B. durch heißes Wasser aus einem ölbeheizten Kessel, der untere Konvektor 1 durch warmes Wasser aus einer Hilfsheizquelle, insbesondere zur Ausnutzung von Sonnenenergie.The examples of a multivalent radiator shown in the drawing are used for room air heating with convectors charged with various energy sources, a lower convector 1/3 and an upper convector 2/4. The convectors 1/3 and 2/4 are arranged in a common air shaft 5 which is open at the top and bottom. They are operated by heating media M 1 and M 2 from different heating sources, the upper convector 2 from a conventional heating source, e.g. by hot water from an oil-fired boiler, the lower convector 1 by warm water from an auxiliary heating source, especially for the use of solar energy.

Die Rohre 1 und 2 der Konvektoren sind mit rechteckigen Lamellen 3 und 4 besetzt.The tubes 1 and 2 of the convectors are covered with rectangular fins 3 and 4.

Zwischen dem Konvektorsystem a der niederen Temperatur und dem Konvektorsystem c der höheren Temperatur befindet sich eine Übergangszone, b, in welcher die miteinander fluchtenden, vertikale Züge 14 bildenden Lamellen 3 und 4 voneinander getrennt sind, entweder durch einen Spalt 8 oder durch Dämmbrücken 11 aus schlecht wärmeleitendem Material, beispielsweise Kunststoff (vgl. Fig. 2, 6 und 7 ).Between the convector system a of the lower temperature and the convector system c of the higher temperature there is a transition zone, b, in which the mutually aligned, vertical trains 14 forming lamellae 3 and 4 are separated from one another, either by a gap 8 or by insulating bridges 11 from bad thermally conductive material, for example plastic (see. Fig. 2, 6 and 7).

In den Ausführungsformen nach Fig. 1, 2 und 3 wird der Schacht durch eine von oben bis unten durchlaufende metallische Schachtuandung 5 begrenzt.In the embodiments according to FIGS. 1, 2 and 3, the shaft is delimited by a metallic shaft wall 5 running from top to bottom.

In allen Ausführungsformen ist in den Wärmeleitweg von dem Konvektorsystem 2/4 zum Konvektorsystem 1/3 eine Wärmedämmzone eingeschaltet, um eine thermische Rückkopplung über Wärmeleitwege zu unterbinden.In all embodiments, a heat insulation zone is switched on in the heat conduction path from the convector system 2/4 to the convector system 1/3 in order to prevent thermal feedback via heat conduction paths.

In der Ausführungsform nach Fig. 1 und 2 ist zur Bildung der Wärmedämmzone die äußere metallene Schachtwandung 5 insgesamt durch eine innere Dämmwandung 6 aus Kunststoff oder sonstigem, schlecht wärmeleitendem Material ausgekleidet. Diese Auskleidung kann, wie Fig. 3 zeigt, in der Übergangszone b unterbrochen sein.In the embodiment according to FIGS. 1 and 2, the outer metallic shaft wall 5 is lined overall by an inner insulating wall 6 made of plastic or other, poorly heat-conducting material to form the thermal insulation zone. 3, this lining can be interrupted in the transition zone b.

In Fig. 4 ist die Auskleidung durch Dämmleisten 7 ersetzt, mit denen die Lamellen 3,4 an die metallene Schachtuandung 5 angeschlossen sind.In Fig. 4 the lining is replaced by insulation strips 7 with which the slats 3, 4 are connected to the metal shaft opening 5.

Die Dämmzonen können auch, wie Fig. 9 zeigt, als Dämmkragen ausgebildet sein, welche sich von Lamelle zu Lamelle dicht aneinander anschließen und ebenfalls eine durchgehende Auskleidung bilden. In Fig. 5 und 1o sind die Lamellen von Konvektor zu Konvektor durch einen einfachen Luftspalt 8 voneinander getrennt, in Fig. 6 und 7 Festkörper-Dämmbrücken 11 (vgl. auch Fig. 2). Diese Ausführungsform zeichnet sich insbesondere dadurch aus, daß über die Konvektorsysteme durchgehende, d.h. ununterbrochene Züge 14 gebildet werden, welche eine ungestörte aufsteigende laminare Luftströmung gewährleisten, welche nur der Thermik unterworfen ist. Damit werden Rückkopplungen sowohl durch Wärmeleitung als auch durch Luftströmung infolge von Wirbelbildungen ausgeschlossen. Die Dämmkörper sind zweckmäßig so ausgeführt, daß Kanten, die zu Turbulenzen führen können, vermieden werden.As shown in FIG. 9, the insulation zones can also be designed as insulation collars, which adjoin one another from lamella to lamella and also form a continuous lining. 5 and 10, the lamellae are separated from one another by convector by a simple air gap 8, in FIGS. 6 and 7 solid-state insulating bridges 11 (cf. also FIG. 2). This embodiment is characterized in particular by the fact that continuous, i.e. continuous trains 14 are formed, which ensure an undisturbed ascending laminar air flow, which is only subjected to the thermals. This prevents feedback from both heat conduction and air flow due to eddy formation. The insulating bodies are appropriately designed so that edges that can lead to turbulence are avoided.

In der Ausführungsform nach Fig. 3 ergibt sich in der Übergangszone b eine Wärmeübertragung aus der Heizenergie des unteren Konvektorsystems auf die metallene Behälterwandung 5. Fig. 5 zeigt eine Ausführungsform, in welcher die Lamellen 4 des oberen Konvektors unmittelbar mit der metallischen Behälterwandung 5 verbunden sind. Die Rückkopplung durch Wärmeleitung zum unteren Konvektor wird durch Einschaltung einer Dämmschranke 9 zwischen der metallischen Wandung oben und unten vermieden. Soll dabei eine Wärmestrahlung im Bereich des oberen Konvektors erfolgen, so können die Lamellen 4 dieses Konvektors wärmeleitend an die obere Schachtwandung 5" angeschlossen werden, während die Lamellen 3 des unteren Konvektors gegen die untere metallene Schachtwandung 5' durch eine Dämmwandung, durch Dämmleisten 6 bzw. 7 oder einen Luftspalt thermisch isoliert sind. Dadurch wird erreicht, daß die Wärmeenergie des unteren Konvektors weitgehendst zur Unterstützung des oberen Konvektors herangezogen wird. An der oberen Austrittsseite des Schachtes kann eine Klappe 15 vorgesehen sein, durch welche eine Prallfläche zur Ablenkung der warmen Luft, beispielsweise zur Fensterfront hin, erfolgt. Diese Klappe kann auch umsetzbar angeordnet sein, so daß im Bedarfsfall eine Umlenkung des Warmluftstromes von der Fensterfront weg in den Raum erreicht wird.In the embodiment according to FIG. 3, in the transition zone b there is heat transfer from the heating energy of the lower convector system to the metal container wall 5. FIG. 5 shows an embodiment in which the lamellae 4 of the upper convector are connected directly to the metallic container wall 5 . The feedback by heat conduction to the lower convector is avoided by switching on an insulating barrier 9 between the metallic wall above and below. If heat radiation is to take place in the area of the upper convector, the slats 4 of this convector can be connected in a heat-conducting manner to the upper shaft wall 5 ", while the slats 3 of the lower convector against the lower metal shaft wall 5 'through an insulating wall, through insulating strips 6 or 7 or an air gap are thermally insulated so that the thermal energy of the lower convector is largely used to support the upper convector. On the upper exit side of the shaft a flap 15 can be provided through which a baffle surface for deflecting the warm air This flap can also be arranged so that it can be deflected so that, if necessary, the warm air flow is deflected away from the window front into the room.

Im Rahmen der Erfindung sind noch mancherlei Abänderungen und andere Ausführungen möglich, insbesondere können auch mehr als zwei Konvektoren in einem gemeinsamen Schacht übereinander angeordnet werden.Various modifications and other designs are possible within the scope of the invention, in particular more than two convectors can also be arranged one above the other in a common shaft.

Ein Heizsystem der Ausführungsform nach Fig. 1 und 2 wurde in Langzeitversuchen getestet. Dabei ergaben sich erhebliche Verbesserungen des Gesamtwirkungsgrades.A heating system of the embodiment according to FIGS. 1 and 2 has been tested in long-term tests. This resulted in significant improvements in overall efficiency.
