Description

Die Erfindung Dezieht sicn auf eine Heizungsanlage gemäß oem Oberbegriff aes Hauptanspruches.The invention is based on a heating system according to OEM Generic term of the main claim.

Eine derartige Heizungsanlage ist Dekannt aus der DT-PS 1 270 769. Eine solcne Heizungsanlage hat die Nachteile, daß bei niearigen Rück lauftemperaturen durcn die tnermostatische Drosselung der Wasserourchsatz im VerDraucherzwei g neraügesetzt wird und es nicnt möglich ist, im Vertraucherzwei g mit Temperaturen, die unterhalu der Taupunktgrenze liegen, zu arbeiten.Such a heating system is Dekannt from DT-PS 1 270 769. Such a heating system has the disadvantages that at low return temperatures by the thermostatic throttling the water flow rate in the consumer branch is reduced and it is not possible to use temperatures in the consumer branch are below the dew point limit to work.

Niedrige Vorlauftemperaturen in Verbindung mit einem großen Wasserdurchsatz und daraus resul tierender. niedri ger Rücklauf temperatur sind jedoch erwünscht bei Strahlungsheizungen, beispielsweise Fußoodenneizungen. Low flow temperatures in connection with a large water throughput and resulting from it. However, lower return temperatures are desirable for radiant heating, such as Fußoodenneizungen.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, bei einer Heizungsanlage der eingangs näher bezeichneten Art vorgenannte Nacnteile zu vermeiden.The present invention is based on the object of the aforementioned in a heating system of the type specified in the introduction Avoid negative parts.

Diese Aufgabe wird bei einer Heizungsanlage der eingangs näher oezeicnneten Art erfindungsgemäß durch das im kennzeichnenden Teil des Hauptanspruches angegebene Merkmal gelöst.In the case of a heating system, this task is described in more detail at the beginning Art according to the invention solved by the feature specified in the characterizing part of the main claim.

Durch Anwendung der Erfindung wird der Vorteil erreicht, daß unter Konstanthaltung des Wasserdurchsatzes im Verbraucnerzweig SchwitzwasseroiIdung in der Wärmequelle vermieden wird.By using the invention, the advantage is achieved that under Keeping the water throughput constant in the condensation water drainage branch in the heat source is avoided.

Weitere Ausgestaltungen und vorteilhafte Weiterbildungen der Erfindung sind aus der nachfolgenden Beschreibung sowie der Figur ersi chtli cn .Further refinements and advantageous developments of the invention are from the following description and the figure ersi chtli cn.

Die Figur zeigt ein Ausführungsbeispiel der Erfindung.The figure shows an embodiment of the invention.

Eine Heizungsanlage 1 mit einer Wärmequelle 2, einer einen Drossel thermostaten 3 aufweisenden Vorlauf1 eitung 4, einem einen oder mehrere Wärmeverbraucher 5 und eine Umwälzpumpe 6 aufweisenden Verbraucherzweig 7 sowie einer Rücklaufleitung 8 enthält eine die Rücklaufleitung 8 und dem in Fließrichtung nach dem Drosselthermostaten 3 angeordneten Teil der Vorlaufleitung 4 verbindende Verbindungsleitung 9 mit einem Überströmventil 10. Der Drosselthermostat 3 ist derartig aufgebaut, daß er In kaltem Zustand nur einen Mindestwasserdurchsatz zuläßt. A heating system 1 with a heat source 2, a flow line 4 having a throttle thermostat 3, a consumer branch 7 having one or more heat consumers 5 and a circulating pump 6 as well as a return line 8 contains a return line 8 and the part arranged in the flow direction after the throttle thermostat 3 the connecting line 9 connecting the flow line 4 with an overflow valve 10. The throttle thermostat 3 is constructed in such a way that it allows only a minimum water throughput in the cold state.

Die Funktion der Anordnung ist folgende:The function of the arrangement is as follows:

Bei Betrieb mit niedrigen Rücklauftemperaturen läßt der Drosselthermostat 3 nur den Mindestwasserdurchsatz zu. Hierdurch baut sich an dem Oberströmventil 10 ein Differenzdruck auf. Das Oberströmventil 10 öffnet somit in Abhängigkeit von dem anstehenden Differenzdruck mehr oder weniger, so daß sich das Rücklaufwasser mit dem Vorlaufwasser mischen kann. Bei steigender Temperatur des Vorlaufwassers öffnet der Drossel thermostat 3 seine Durchflußstrecke, so daß der an dem Oberströmventil 10 anstehende Differenzdruck kleiner wird und somit die Rate des umlaufenden Wassers über den Wärmetauscher 2 langsam größer wird. Wenn schließlich die Temperatur in der Vorlaufleitung 4 so groß ist, daß sich im Wärmetauscher 2 kein Schwitzwasser mehr bilden kann, öffnet der When operating with low return temperatures , the throttle thermostat 3 only allows the minimum water throughput. As a result, a differential pressure builds up at the overflow valve 10. The overflow valve 10 thus opens more or less depending on the differential pressure present, so that the return water can mix with the feed water. When the temperature of the flow water rises, the throttle thermostat 3 opens its flow path, so that the differential pressure applied to the overflow valve 10 is smaller and thus the rate of the circulating water over the heat exchanger 2 is slowly increasing. Finally, when the temperature in the flow line 4 is so high that condensation can no longer form in the heat exchanger 2, the opens

Drossel thermostat 3 seine Durchflußstrecke ganz. Dies hat zur Folge, daß der Differenzdruck, der an dem Überströmventil ansteht, so klein ist, daß dieses nicht mehr anspricht, d. h., der gesamte Wasserdurchsatz geht jetzt über die Wärmequelle.Throttle thermostat 3 its flow range all the way. This has the consequence that the differential pressure which is present at the overflow valve is so small that it no longer responds, that is, the entire water throughput is now via the heat source.
