Description
Regelung der Heizleistung eines Elektrokessels Elektrokessel werden immer häufiger in Heizungsanlagen eingesetzt. Ihre Anwendung erfolgt besonders in Nachtstrom-Wärmespeicher-Anlagen, bei denen das Umlaufwasser nachts erwärmt. Control of the heating output of an electric boiler can be an electric boiler used more and more in heating systems. They are used especially in Night electricity heat storage systems in which the circulating water is heated at night.
und in Behältern gespeichert wird. EinetDirektheizung ist ebenfalls möglich.and stored in containers. One direct heating is also available possible.
Der Elektrokessel kann in Ein-Aus-Schaltung betriebenwerden, d.h. bei Bedarf wird die volle Heizleistung eingeschaltet und bei Erreichen der gewünschten Temperatur wird die Stromzufuhr unterbrochen. Eine solche Schaltung ist nicht vorteilhaft, da bereits bei geringer Wärmeanforderung die volle Heizleistung zugeführt werden muß. Es entsteht ein häufiges Schalten.The electric boiler can be operated in an on-off circuit, i.e. If necessary, the full heating output is switched on and when the desired one is reached Temperature, the power supply is interrupted. Such a circuit is not advantageous, because the full heating output is supplied even with a low heat requirement got to. Frequent switching occurs.
Umgekehrt wäre es möglich, die Heizleistung in Abhängigkeit von der jeweils angeforderten Wärmemenge stetig zu regeln. Auf diese Weise wäre eine einwandfreie anpassung an die tatsächlichen Gegebenheiten möglich. Solche Regelvorrichtungen sind jedoch sehr teuer und aufwendig, so daß sie in Heizungsanlagen nicht eingesetzt werden.Conversely, it would be possible to adjust the heating power as a function of the to regulate the required amount of heat continuously. That way it would be flawless adaptation to the actual circumstances possible. Such regulating devices however, they are very expensive and complex, so that they are not used in heating systems will.
Eine bekannte Zwischenlösung besteht darin, die Heizleistung in Stufen zu schalten. Je nach der benötigten Wärmemenge werden die einzelnen Stufen in Abhängigkeit von einem Außen-, Raum-und/oder Vorlaufthermostaten zu bzw. abgeschaltet. Auf diese Weise ist eine weitgehende Anpassung an die geforderte fleizleistung des Elektrokessels möglich. Man nimmt dabei die Ungenauigkeit infolge der Stufenschaltung bewußt in Kauf. Die Regelung erfolgt also nicht stetig, sondern nur in Stufen.A well-known interim solution is to increase the heating power in stages to switch. The individual stages are dependent on the amount of heat required switched on or off by an outdoor, room and / or flow thermostat. To this Way is an extensive adjustment to the required performance of the electric boiler possible. The inaccuracy due to the step switching is consciously taken into account Purchase. the Regulation does not take place continuously, but only in stages.
Durch die vorliegende Erfindung soll auch diese Ungenauigkeit vermieden werden. Die Regelung soll stetig erfolgen, ohne jedoch eine aufwendige Regelvorrichtung anzuwenden. -Es wird vorgeschlagen, die Regelung sier Heizleistung eines Elektrokessels in' bekannter Weise in mehreren Stufen vorzunehmen und eine dieser Stufen stetig regelbar zu gestalten Die Regelung erfolgt dabei so, daß die Anzahl der jeweils eingeschalteten nicht stetig geregelten Stufen in Abhängigkeit-von der geforderten Heizleistung verändert wird und daß die genaue Regelung in jedem Fall durch die stetig geregelte Stufe vorgenommen wird.The present invention is also intended to avoid this inaccuracy will. The regulation should take place continuously, but without an expensive regulating device apply. -It is proposed to regulate the heating output of an electric boiler to make in 'a known manner in several stages and one of these stages steadily to be controllable The regulation takes place in such a way that the number of each Switched on, not continuously regulated stages depending on the required Heating power is changed and that the exact regulation in each case by the continuously regulated level is carried out.
Zur Erläuterung der Erfindung sei angenommen, daß 3 Leistungsstufen mit jeweils 1/5 der gesamten Heizleistung vorhanden sind. Im oberen Leistungsbereich sind alle Stufen eingeschaltet. Die gleitende Regelung zwischen 2/3 der Leistung und der vollen Leistung erfolgt durch die stetig regelbare Stufe. Im mittleren Leistungsbereich erfolgt die Energie zufuhr durch eine nicht regelbare Stufe und durch die stetig regelbare Stufe. Im unteren Leistungsbereich ist nur die stetig regelbare Stufe eingeschaltet.To explain the invention, it is assumed that 3 power levels with 1/5 of the total heating output. In the upper performance range all stages are switched on. The sliding regulation between 2/3 of the power and full power is achieved through the continuously adjustable level. In the medium performance range the energy is supplied through a non-controllable level and through the steady adjustable level. Only the continuously adjustable level is in the lower performance range switched on.
Eine andere Aufteilung der Leistungsstufen ist ebenfalls möglich.Another division of the performance levels is also possible.
Durch diese Erfindung kann die Heizleistung des Elektrokessels über den gesamten Leistungsbereich stetig geregelt werden. Die Vorrichtung für- -die st-etig regelbare Leistungsstufe ist weit preisgünstiger herzustellen als die Vorrichtung für die stufenlose Regelung der Gesamtleistung.With this invention, the heating power of the electric boiler can be over the entire range of services are continuously regulated. The device for- -the Constantly controllable power level is far cheaper to manufacture than the device for the stepless regulation of the total output.
Bei genauer Einstellung der Vorlauf temperatur, die mit der erfindungsgemäßen Regelvorrichtung einzuhalten ist, kann auf eine separate Heizkreisregelung verzichtet werden.With a more precise setting of the flow temperature with the inventive Control device must be observed, a separate heating circuit control can be dispensed with will.
Die beigefügte Zeichnung zeigt ein Ausführungsbeispiel der Erfindung.The attached drawing shows an embodiment of the invention.
Im Elektrokessel 1 sind die Helzelemente 2 , 5, 4 angeordnet, welche über das Schaltgerät 5 mit dem Stromnetz verbunden sind. In Abhängigkeit von der Außentemperatur werden die einzelnen Heizelemente eingeschaltet. Dem stetig regelbaren Heizelement 4 ist ein-Zentralgerät 6 vorgeschaltet, welches -die zugeführte Heizleistung in Abhängigkeit von dem Außenthermostat 7 und dem Vorlaufthermostat 8 regelt.In the electric boiler 1, the heating elements 2, 5, 4 are arranged, which are connected to the power grid via the switching device 5. Depending on the Outside temperature, the individual heating elements are switched on. The continuously adjustable Heating element 4 is preceded by a central device 6, which - the supplied heating power depending on the external thermostat 7 and the flow thermostat 8 regulates.
Die nicht regelbaren Heizelemente 2 , 5 werden nur mit voller Heizleistung ein- bzw. ausgeschaltet. Über die Umwälzpumpe 9 wird das aufgeheizte Wasser bei Bedarf den Heizkörpern 10 zugeführt.The non-adjustable heating elements 2, 5 are only at full heating power switched on or off. About the circulation pump 9, the heated water is at The radiators 10 are supplied as required.
