Description

Die Erfindung betrifft einen von einem Wärmeträgermedium durchströmten Heizkörper, insbesondere Unterflur-Konvektor, dem ein Ventilator zur Erzeugung einer Luftströmung durch die Heizfläche zugeordnet ist.The invention relates to a heating element through which a heat transfer medium flows, in particular an underfloor convector, which is assigned a fan for generating an air flow through the heating surface.

Aus der DE-OS 29 36 855 ist bereits ein Konvektor zur Anbringung in einem in den Boden eingelassenen Schacht bekannt, der mit einem Rost abgedeckt ist, wobei der Konvektor vorzugsweise thermostatgesteuert ist (siehe S. 5, zweiter Abs.) und in dem den Konvektor durchströmenden Luftstrom ein Ventilator angeordnet ist. Die dadurch gegebene Regelung ist aber erfahrungsgemäß nur ungenau.From DE-OS 29 36 855 a convector for attachment in a recessed in the ground Well known, which is covered with a grate, wherein the convector is preferably thermostat-controlled is (see p. 5, second paragraph) and a fan in the air flow flowing through the convector is arranged. However, experience has shown that the resulting regulation is only imprecise.

Es ist demgegenüber Aufgabe der Erfindung, einen Heizkörper der oben angegebenen Art zu schaffen, bei dem der durch die Heizfläche strömende Luftstrom in direkter Abhängigkeit von dem Wärmeträgerstrom bzw. der Leistung des Heizkörpers selbsttätig einstellbar ist.In contrast, it is the object of the invention to provide a radiator of the type specified above, in that of the air flow flowing through the heating surface as a direct function of the heat transfer medium flow or the output of the radiator is automatically adjustable.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der eingangs genannte Heizkörper dadurch gekennzeichnet ist, daß eine durch den Wärmeträger- so strom angetriebene Turbine vorgesehen ist, durch die der Ventilator antreibbar ist.According to the invention, this object is achieved in that the radiator mentioned at the outset thereby is characterized in that a turbine driven by the heat transfer medium is provided through which the fan can be driven.

Vorteilhaft zur Einstellung eines gleichmäßigen Luftstromes über die ganze Länge des Heizkörpers kann der Ventilator ein Querstromgebläse sein und seine Länge kann nahezu der des Heizkörpers entsprechen.Advantageous for setting a uniform air flow over the entire length of the radiator the fan can be a cross-flow fan and its length can be close to that of the radiator correspond.

Eine besonders einfache Ausführung besteht darin, daß die Turbine ein tangential angeströmtes Flügelrad sein kann und zur Einstellung einer wünschenswert hohen Drehzahl der Turbine kann der das Heizmedium dem Flügelrad zuführende Kanal im Bereich der Anströmung des Flügelrades eine Verengung aufweisen.A particularly simple embodiment is that the turbine is an impeller with a tangential flow can be and to set a desirable high speed of the turbine can be the heating medium the channel leading to the impeller have a constriction in the area of the flow towards the impeller.

Zur Einstellung der medizinisch günstigsten Luftfeuchtigkeit in dem überheizten Raum kann weiterhin unterhalb oder oberhalb des Ventilators im Bereich des Luftstroms ein Behälter für Befeuchtungswasser vorhanden sein.To set the medically most favorable air humidity in the overheated room can continue A container for humidifying water is provided below or above the fan in the area of the air flow be.

Erfindungsgemäß ist es also sichergestellt, daß die Leistung des Gebläses der Wärmeübertragung des Konvektors direkt angepaßt ist und angesichts der Einfachheit der erfindungsgemäßen Einrichtung kann von einer idealen Lösung der anstehenden Probleme gesprochen werden.According to the invention it is thus ensured that the performance of the fan of the heat transfer of the Convector is directly adapted and given the simplicity of the device according to the invention can speak of an ideal solution to the problems at hand.

Im folgenden wird ein Ausführungsbeispiel der Erfindung anhand von Zeichnungen naher beschrieben. Es zeigtIn the following an embodiment of the invention is described in more detail with reference to drawings. It shows

F i g. 1 einen Querschnitt durch einen Konvektor gemäß der Erfindung innerhalb eines Bodenschachtes,F i g. 1 shows a cross section through a convector according to the invention within a floor shaft,

F i g. 2 einen Schnitt durch die den Querstromlüfter antreibende Turbine undF i g. 2 shows a section through the turbine driving the cross-flow fan and

Fig.3 einen Schnitt durch die Turbine im rechten Winkel zu dem Schnitt gemäß F i g. 2.3 shows a section through the turbine at a right angle to the section according to FIG. 2.

Innerhalb eines mit einer Auskleidung 3 versehenen Schachtes ist ein Konvektor 1 angeordnet, neben dem ein Querstromgebläse 2 vorhanden ist. Die Luft wird jetzt von dem Querstromgebläse gemäß den eingezeichneten Pfeilen durch den nicht gezeigten Rost angesaugt, unter den Konverter geleitet und durchströmt diesen mit Unterstützung der Naturkonvektion von unten nach oben und tritt dann nach oben in den zu beheizenden Raum aus.Within a shaft provided with a lining 3, a convector 1 is arranged, next to the a cross-flow fan 2 is present. The air is now drawn from the cross-flow fan according to the Arrows sucked through the grate, not shown, passed under the converter and flowed through this with the support of natural convection from bottom to top and then enters the top heating room.

Vorteilhaft auf der verlängerten Welle des Querstromgebläses 2 sitzt eine Turbine in Form eines Flügelrades 5, welches sich in einem wasserdichten Gehäuse 6 dreht. Die Welle 8 ist mittels Lager 7 gelagert und ein Austritt des Heizmediums wird durch Dichtringe 9 (O-Ringe) sicher vermieden, wobei diese Dichtringe nur einseitig an der aus dem Gehäuse herausführenden Welle angeordnet zu sein brauchen. Die Lager 7 können Nadellager sein, da sie aber durch das Heizmedium laufend flüssigkeits-geschmiert sind, können sie auch aus geeignetem Kunststoff, Buntmetall oder ähnlichem bestehen. Das Heizmedium wird über ein Anschlußrohr 10 zugeführt, welches sich vor dem Flügelrad 5 verengt (bei 11) und dadurch kann die Strömung des Heizmediums so weit erhöht werden, daß die benötigte Umdrehungszahl der Turbine bzw. des Flügelrades 5 eingestellt wird. Bei Verwendung einer einstellbaren Drossel kann weiterhin eine Regelung der gewünschten Drehzahl erfolgen.A turbine in the form of a is advantageously seated on the extended shaft of the cross-flow fan 2 Impeller 5, which rotates in a waterproof housing 6. The shaft 8 is supported by bearings 7 and leakage of the heating medium is reliably prevented by sealing rings 9 (O-rings), these Sealing rings only need to be arranged on one side of the shaft leading out of the housing. The bearings 7 can be needle bearings, but since they are continuously liquid-lubricated by the heating medium, they can also consist of suitable plastic, non-ferrous metal or the like. The heating medium is over a connecting pipe 10 supplied, which narrows in front of the impeller 5 (at 11) and thereby the Flow of the heating medium can be increased so that the required number of revolutions of the turbine or the Impeller 5 is set. If an adjustable throttle is used, it is still possible to regulate the desired speed.

Das Heizmedium fließt jetzt durch das Rohr 10 zu der Turbine bzw. dem Flügelrad 5 und dann durch einen nicht gezeigten, weiteren Anschluß zu dem Konvektor 1. Dadurch wird, wie beschrieben, gewährleistet, daß die Stärke des Luftstroms direkt von der Heizleistung des Konvektors abhängig ist.The heating medium now flows through the pipe 10 to the turbine or the impeller 5 and then through a not shown, further connection to the convector 1. This ensures, as described, that the Strength of the air flow is directly dependent on the heating output of the convector.

Bei Radiatoren ist das beschriebene Prinzip ebenfalls verwendbar; es wird die Temperatur in dem Bodenschacht verringert und dadurch unter Umständen eine unnötige Wärmeabfuhr vermieden. Die Leistung des Radiators kann erhöht werden, die Oberflächentemperatur gesenkt werden und dadurch können Radiatoren auch mit gegebenenfalls wünschenswerten geringeren Temperaturen des Heizmediums betrieben werden. Im übrigen eignet sich die Erfindung aber für Konvektoren im besonderen Maße.The principle described can also be used for radiators; it becomes the temperature in the bottom shaft and thus possibly avoided unnecessary heat dissipation. The performance of the Radiators can be increased, the surface temperature can be reduced and this allows radiators can also be operated with possibly desirable lower temperatures of the heating medium. in the Otherwise, however, the invention is particularly suitable for convectors.

Der Zufluß des Heizmediums kann thermostatgesteuert werden, bei einem Absperren des Zuflusses läuft selbstverständlich der Querstromlüfter oder Ventilator 2 nicht.The inflow of the heating medium can be controlled by a thermostat, when the inflow is shut off of course the cross-flow fan or fan 2 not.

Falls eine Thermostatsteuerung des Konvektors aber nicht erfolgt, ist selbstverständlich durch die beschriebene Verbindung gewährleistet, daß bei höheren Heizmitteldurchflüssen eine genügend große Luftumwälzung erfolgt.If there is no thermostat control of the convector, it is of course possible to use the one described Connection ensures that with higher heating medium flows a sufficiently large air circulation he follows.

Die beschriebene Einrichtung ist nicht nur auf Konvektoren oder dergleichen beschränkt, sondern läßt sich in Verbindung mit wärmeabgebenden Flächen aller Art, also auch Plattenkonvektoren und dergleichen, verwenden. Besonders wichtig ist dabei, daß die wärmeabgebende Fläche eine niedrige Temperatur aufweisen kann, sonst also nicht nutzbare Wärme zur Raumheizung verwendet werden kann. Der beschriebene Heizkörper eignet sich also besonders gut zur Verwertung von aus Wärmepumpen stammenden Heizströmen geringer Temperatur.The device described is not limited to convectors or the like, but leaves in connection with heat-emitting surfaces of all kinds, including plate convectors and the like, use. It is particularly important that the heat-emitting surface has a low temperature can have, so otherwise unusable heat can be used for space heating. The one described Radiators are therefore particularly suitable for the recovery of heat pumps Low temperature heating currents.

Bei Anordnung eines wasserenthaltenden Gefäßes im Bereich des Luftstroms läßt sich weiterhin besonders einfach und wirtschaftlich die für Wohnräume günstigste Luftfeuchtigkeit einstellen, wobei gewährleistet wird, daß die Verdunstung bzw. Wasserabgabe proportional der Leistung der Heizung eingestellt wird. Erstmalig kann also bei hoher Heizleistung auch eine hohe Verdunstungsleistung eingestellt werden, die bei geringer Heizleistung entsprechend automatisch verringert wird.If a water-containing vessel is arranged in the area of the air flow, it is also particularly possible to Easily and economically set the air humidity that is most favorable for living spaces, whereby this is guaranteed is that the evaporation or water output is adjusted proportionally to the power of the heater. For the first time, a high evaporation output can also be set with a high heating output, which at low heating power is automatically reduced accordingly.
