Description

Einrichtung zur TemperaturregelungTemperature control device
Technisches GebietTechnical field
Die Erfindung betrifft eine Einrichtung zur Temperaturregelung für eine elektrische Fußbodenheizung mit im Boden verlegten Heizleitern.The invention relates to a device for temperature control for an electric floor heating system with heating conductors installed in the floor.
Stand der TechnikState of the art
Die Temperatur eines Raumes wird häufig mit Hilfe eines Raumthermostaten geregelt, der meist durch einen Bimetallsensor gesteuert ist. Oft sind solche Regelungen mit einem Zeitschalter kombiniert. Nach der Einführung von Fußbodenheizungen - sei es mit elektrischen Heizleitern oder mit armwasserleitungen aus Plastik- oder Kupferrohren - ist es bekannt, den Temperaturanstieg im Boden zu begrenzen, insbesondere um eine unzulässig hohe Bodentemperatur zu verhindern, die gesundheitliche Schäden für die Bewohner verursachen kann. Zur Begrenzung der Bodentemperatur können Sensoren innerhalb des Bodens nahe der elektrischen Heizleiter installiert werden. Damit sind jedoch verschiedene Probleme verbunden. Wenn einmal ein Sensor in dem Boden eingebaut ist und nicht mehr funktioniert, kann er nicht mehr die Temperatur im Boden kontrollieren, was umständliche Reparaturarbeiten zum Austausch des Sensors erfordert . Zur Lösung dieses Problems kann bei Neubauten zwar ein Leerrohr zur Aufnahme des Sensors in den Boden eingebracht werden. Eine nachträgliche Installation in bestehende Böden ist jedoch sehr teuer.The temperature of a room is often controlled with the help of a room thermostat, which is usually controlled by a bimetal sensor. Such regulations are often combined with a timer. After the introduction of underfloor heating - be it with electrical heating conductors or with arm water pipes made of plastic or copper pipes - it is known to limit the temperature rise in the floor, in particular to prevent an inadmissibly high floor temperature, which can cause health damage to the residents. To limit the floor temperature, sensors can be installed inside the floor near the electrical heating conductors. However, there are various problems associated with this. Once a sensor is installed in the floor and no longer works, it can no longer control the temperature in the floor, which requires laborious repair work to replace the sensor. To solve this problem, an empty pipe can be installed in the floor to accommodate the sensor in new buildings. Subsequent installation in existing floors is very expensive.
Darstellung der ErfindungPresentation of the invention
Aufgabe der vorliegenden Erfindung ist es, eine Einrichtung zur Temperaturregelung für eine elektrische Fußbodenheizung anzugeben, welche die obengenannten Nachteile nicht aufweist .The object of the present invention is to provide a device for temperature control for an electric floor heating which does not have the disadvantages mentioned above.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß in einem Rohr, das die elektrischen Zuleitungen zu den Heizleitern enthält und oberhalb des Bodens angeordnet ist, ein Temperatursensor angeordnet ist und daß mindestens eine Zuleitung mindestens auf einem Teil ihrer Länge als weiterer Heizleiter ausgebildet ist. Dabei kann aus Sicherheitsgründen vorgesehen sein, daß der weitere Heizleiter Teil einer spannungführenden Leitung (Phase) ist.This object is achieved in that a temperature sensor is arranged in a tube which contains the electrical leads to the heating conductors and is arranged above the floor, and that at least one supply line is designed as an additional heating conductor over at least part of its length. For safety reasons, it can be provided that the further heat conductor is part of a live line (phase).
Der Erfindung liegt die Erkenntnis zugrunde, daß auch eine Temperaturmessung in der Nähe eines Heizleiters außerhalb des Bodens eine gute Regelung ermöglicht . Um eine Anpassung des weiteren Heizleiters an die Anzahl von im Boden verlegten Heizleitern zu ersparen, kann gemäß einer Weiterbildung vorgesehen sein, daß beim Anschluß mehrerer Heizleiter nur einer der Heizleiter über den weiteren Heizleiter angeschlossen ist und daß die anderen Heizleiter über Kupferleitungen angeschlossen sind.The invention is based on the finding that a temperature measurement in the vicinity of a heating conductor outside the floor also enables good control. In order to save an adaptation of the further heating conductor to the number of heating conductors laid in the floor, it can be provided according to a further development that when connecting several heating conductors only one of the heating conductors is connected via the further heating conductor and that the other heating conductors are connected via copper lines.
Eine vorteilhafte Ausgestaltung der Erfindung besteht darin, daß das Rohr zwischen einem an den Temperatursensor angeschlossenen Regelgerät und einem in Fußbodennähe vorgesehenen Anschlußkasten für die Heizleiter angeordnet ist .An advantageous embodiment of the invention is that the pipe between a control device connected to the temperature sensor and one near the floor provided connection box for the heating conductor is arranged.
Zur Erzielung eines besonders günstigen Regelverhaltens dient eine weitere vorteilhafte Ausgestaltung dadurch, daß der weitere Heizleiter im wesentlichen die gleiche elektrische Leistung pro Längeneinheit aufnimmt wie der über ihn versorgte Heizleiter.A further advantageous embodiment is used to achieve a particularly favorable control behavior in that the further heating conductor consumes essentially the same electrical power per unit length as the heating conductor supplied via it.
Vorzugsweise ist bei der Erfindung vorgesehen, daß die Länge des weiteren Heizleiters kleiner als die Länge des Rohres ist und daß der weitere Heizleiter über Kupferleitungen an das Regelgerät und an den Anschlußkasten angeschlossen ist. Dabei kann der Temperatursensor am oberen Ende des weiteren Heizleiters angeordnet sein, was eine Anordnung an anderer Stelle nicht ausschließt.It is preferably provided in the invention that the length of the further heating conductor is less than the length of the tube and that the further heating conductor is connected to the control device and to the connection box via copper lines. The temperature sensor can be arranged at the upper end of the further heating conductor, which does not rule out an arrangement at another point.
Eine ausreichende Erwärmung des Temperatursensors ergibt sich insbesondere dann, wenn der Heizleiter etwa die Hälfte des Abstandes zwischen Regelgerät und Anschlußkasten einnimmt .Adequate heating of the temperature sensor results in particular when the heating conductor takes up about half the distance between the control device and the connection box.
Ferner kann bei der Erfindung vorgesehen sein, daß das Regelgerät etwa 1,5m und der Anschlußkasten etwa 30cm über dem Boden angeordnet sind.Furthermore, it can be provided in the invention that the control device is arranged approximately 1.5 m above the floor and the junction box approximately 30 cm.
Die Erfindung bewirkt außer einer guten Regelung der Bodentemperatur auch eine Regelung der Raumtemperatur. Sollte dies im Einzelfall nicht genügen, kann gemäß einer Weiterbildung vorgesehen werden, daß an das Regelgerät ein weiterer Temperatursensor zur Messung der Raumtemperatur angeschlossen ist. Kurze Beschreibung der ZeichnungenIn addition to a good regulation of the floor temperature, the invention also regulates the room temperature. If this is not sufficient in individual cases, it can be provided according to a further development that a further temperature sensor for measuring the room temperature is connected to the control device.
