Abstract
Description
Es ist heute Stand der Technik die Heizungsvorlauftemperatur, insbesonders bei Zentralheizungen, in Abhängigkeit von der Außentemperatur zu regeln. Die gewünschte Vorlauftemperatur wird mit Hilfe der sogenannten Heizungskennlinie und der gemessenen Außenlufttemperatur berechnet, und als Sollwert auf den Kesseltemperaturregler gegeben.The state of the art today is the heating flow temperature, especially at Central heating to regulate depending on the outside temperature. The desired The flow temperature is measured using the so-called heating curve and the measured Outside air temperature calculated and given as setpoint to the boiler temperature controller.
Der im Patentanspruch 1 angegebenen Erfindung liegt das Problem zugrunde, daß bei diesem Verfahren die tatsächlich über die installierten Heizkörper abgegebene Wärmemenge unberücksichtigt gelassen wird.The invention specified in claim 1 is based on the problem that with this Processes the amount of heat actually emitted via the installed radiators is ignored.
Im Extremfall kann es vorkommen, daß der gesamte Heizkreislauf auf der Solltemperatur gehalten wird, obwohl alle angeschlossenen Heizungsventile abgesperrt sind. Dies kommt insbesonders bei älteren Anlagen häufig vor, da die installierten Heizkörper erfahrungsgemäß überdimensioniert sind.In extreme cases it can happen that the entire heating circuit is at the set temperature is held, although all connected heating valves are shut off. This is coming especially in older systems, because experience shows that the installed radiators are oversized.
Dieses Problem wird mit denen im Patentanspruch 1 aufgeführten Merkmalen gelöst.This problem is solved with the features listed in claim 1.
- - Abschaltung des Heizungsbrenners bei Überschreiten einer eingestellten Rücklauftemperatur.- The heating burner is switched off when a set one is exceeded Return temperature.
- - Abschalten des Heizungsbrenners bei Unterschreiten einer eingestellten Differenztemperatur zwischen Vor.- u. Rücklauf.- The heating burner is switched off when the temperature falls below a set value Difference temperature between Vor.- u. Rewind.
Die mit der Erfindung erzielten Vorteile liegen insbesondere darin, daß ein übermäßiges Erwärmen des Heizungskreislaufes, über den tatsächlichen Bedarf hinaus, verhindert wird.The advantages achieved with the invention are in particular that an excessive Heating of the heating circuit, beyond the actual need, is prevented.
Eine weitere Ausbaumöglichkeit besteht darin, die in Patentanspruch 2 genannte Drehzahlverstellung der Heizkreispumpe in das System zu integrieren. Durch die Drehzahlabsenkung der Pumpe wird eine bessere Wärmeabgabe über die Heizkörper ermöglicht, und ein übermäßiges erwärmen des Heizkreislaufes ebenfalls verhindert.Another expansion possibility is that mentioned in claim 2 Integrate the speed adjustment of the heating circuit pump into the system. Through the Lowering the speed of the pump will give better heat dissipation through the radiators enables, and excessive heating of the heating circuit also prevented.
Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben.An embodiment of the invention is shown in the drawing and is in following described in more detail.
Fig. 1 Fühler Rücklauftemperatur. Dieser ist als Anlegefühler ausgeführt und wird an der Rücklaufleitung befestigt. Fig. 1 return temperature sensor. This is designed as a contact sensor and is attached to the return line.
Fig. 2 Fühler Vorlauftemperatur. Dieser Anlegefühler wird an der Vorlaufleitung befestigt. Fig. 2 flow temperature sensor. This contact sensor is attached to the flow line.
Fig. 3 Vergleicher auf Mindestrücklauftemperatur. Dieser wird mit Hilfe von Potentiometer (Fig. 8) auf eine Solltemperatur des Rücklaufes eingestellt, die nicht unterschritten werden darf. Auf diese Weise kann die Anlage auf die Güte der vorhandenen Gebäudeheizung eingestellt werden. Fig. 3 comparator on minimum return temperature. This is set using a potentiometer ( Fig. 8) to a set temperature of the return, which must not be fallen below. In this way, the system can be adjusted to the quality of the existing building heating.
Fig. 4 Vergleicher auf Temperaturdifferenz zu gering. Unterschreitet die Differenz (Vor./Rücklauf) eine mit Potentiometer (Fig. 9 ) eingestellten Wert, so wird die Brennerabschaltung aktiviert. Eine geringe Temperaturdifferenz läßt auf geschlossene Heizungsventile schließen. Fig. 4 comparator on temperature difference too low. If the difference (forward / return) falls below a value set with the potentiometer ( Fig. 9), the burner shutdown is activated. A small temperature difference indicates that the heating valves are closed.
Fig. 5 Vergleicher auf Höhe der Rücklauftemperatur. Überschreitet diese einen mit Potentiometer ( Fig. 10) eingestellten Wert, so wird die Brennerabschaltung aktiviert. Fig. 5 comparator at the level of the return temperature. If this exceeds a value set with the potentiometer ( Fig. 10), the burner shutdown is activated.
Fig. 13 Vergleicher auf Rücklauftemperatur < Vorlauftemperatur. Ist diese Situation gegeben so läßt das auf Brauchwassererhitzung schließen. In diesem Fall wird die Brennerabschaltung deaktiviert um ein schnelles Erhitzen des Brauchwassers zu ermöglichen. Das Potentiometer (Fig. 12) dient zum Abgleich dieser Funktion. Fig. 13 Comparator on return temperature <flow temperature. If this situation exists, this indicates that hot water has been heated. In this case, the burner shutdown is deactivated to enable the domestic water to be heated up quickly. The potentiometer ( Fig. 12) is used to adjust this function.
Fig. 6 Dieses Zeitglied wird bei aktivierter Brennerabschaltung für eine mit Potentiometer (Fig. 11) eingestellte Zeit gestartet und blockiert über Relais (Fig. 7) die vorhandene Brenneranteuerung. Fig. 6 This timer is started when the burner shutdown is activated for a time set with the potentiometer ( Fig. 11) and blocks the existing burner control via relays ( Fig. 7).
Fig. 14 Dieser Drehzahlsteller verringert bei Ansprechen der Vergleicher (Fig. 4 oder Fig 5 ) die Drehzahl der Heizkreispumpe, und ermöglicht eine verbesserte Wärmeabgabe im Heizsystem. Fig. 14 This speed controller reduces the speed of the heating circuit pump when the comparators ( Fig. 4 or Fig. 5 ) respond, and enables improved heat dissipation in the heating system.
