Abstract

Central heating installation with a condensation boiler (1) and consumers (5) controlled via thermostat valves (4), in which an overflow valve (7) is connected hydraulically in antiparallel with a circulating pump (3). The circulating pump (3) and the overflow valve (7) can be assembled to form a structural unit. <IMAGE>

Description

Heizungsantage mit einem KondensationskesselHeating system with a condensation boiler

Die vorliegende Erfindung betrifft eine Heizungsanlage mit einem Kondensationskessel und den im Oberbegriff des Patentanspruchs 1 angeführten Merkmalen.The present invention relates to a heating system with a condensation boiler and to that described in the preamble of claim 1 listed features.

Solche Heizungsanlagen mit einem Kondensationskessel sind bekannt. Sie weisen eine Umwälzpumpe in einer Vorlauf leitung auf, welche das Vorlaufwasser über Thermostatventile an Verbraucher liefert.Such heating systems with a condensation boiler are known. They have a circulation pump in a feed line, which supplies the feed water to consumers via thermostatic valves.

In den Verbrauchern wird das Vorlaufwasser durch Abgabe der Wärme an die zu beheizenden Räume abgekühlt und durch eine Rücklauf leitung in den Kondensationskessel zurückgeführt. Ein zu den Thermostatventilen und zu den Verbrauchern parallel liegendes UeberströmventiI lässt beim Schliessen der Thermostatventile das Vorlaufwasser direkt in die Rücklauf leitung fMessen. Dies hat den Nachteil, dass das auf die VorIauftemperatur aufgeheizte Vorlaufwasser die Rücklauftemperatur der Heizungsanlage erhöht. Die Erhöhung der RückIauftemperatur hat zur Folge, dass die für einen sparsamen Betrieb des Kondensationskessels erwünschte maximale Kondensation in der Rücklaufleitung nicht stattfinden kann.In the consumers, the flow water is cooled by releasing the heat to the rooms to be heated and through a return line returned to the condensation boiler. An overflow valve parallel to the thermostatic valves and the consumers leaves the flow water directly when the thermostatic valve closes into the return line fMeasuring. This has the disadvantage that the the flow water heated to the flow temperature the return temperature the heating system increased. The increase in the return temperature As a result, the maximum condensation in the return line, which is desired for economical operation of the condensation boiler cannot take place.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, diesen Nachteil zu beseitigen und eine Heizungsanlage zu schaffen, bei welcher darüber hinaus die Wassermenge im Verbraucherkreis variabel gemacht und damit die Verweilzeit des Wassers im Heizkreis beim Schliessen der Thermostatventile vergrössert werden kann. Die Vergrösserung der Verweilzeit hat zur Folge, dass das Rücklaufwasser immer eine möglichst niedrige Temperatur aufweist, womit eine maximale Kondensation möglich wird.The present invention is based on this disadvantage to eliminate and to create a heating system in which the amount of water in the consumer circuit is also made variable and thus the residence time of the water in the heating circuit when the thermostat valves are closed can be increased. The enlargement the dwell time has the consequence that the return water always has the lowest possible temperature, with which a maximum condensation becomes possible.

Die gestellte Aufgabe ist durch Merkmale des Patentanspruches 1 gelöst.The stated problem is solved by the features of claim 1.

Ein Ausführungsbeispiel des Gegenstandes der Erfindung wird nachfolgend anhand einer einzigen schematischen Zeichnung näher beschrieben.An embodiment of the subject matter of the invention is shown below described in more detail using a single schematic drawing.

π «Γ - ♦- ι. ^π «Γ - ♦ - ι. ^

Eine Heizungsanlage weist einen Kondensationskessel 1 auf, welcher mit Hilfe einer in ihrer Vorlauf leitung 2 liegenden Umwälzpumpe 3 heisses Wasser über Thermostatventile 4 an Verbraucher 5 liefert, die über eine Rücklauf leitung 6 mit dem Kondensationskessel 1 verbunden sind. Ein UeberströmventiI 7 ist zwischen der Saugseite und der Druckseite der Umwälzpumpe 3 unmittelbar an dieser hydraulisch so angeschlossen, dass seine Durchlassrichtung der Durchflussrichtung der Umwälzpumpe 7 entgegengesetzt ist, das heisst, das UeberströmventiI 7 ist zur Umwälzpumpe 3 hydraulisch antiparallel geschaltet. Beim Schliessen der Thermostatventile 4 fliesst durch das UeberströmventiI 7 Vorlaufwasser also in Gegenrichtung zum Vorlaufstrom, wie dies durch Pfeile in der Zeichnung gezeigt ist. Durch diese Anordnung des UeberströmventiIs 7 wird erzielt, dass die Wassermenge im Verbraucherkreis variabel und damit die Verweilzeit beim Schliessen der Thermostatventile 4 grosser wird. Da kein Vorlaufwasser direkt in die Rücklauf leitung 6 gelangt, besteht in der Rücklauf leitung 6 immer die niedrigst mögliche RückIauftemperatur des Wassers, was eine für einen ökonomischen Betrieb des Kondensationskessels 1 erwünschte grösstmögliche Kondensation ergibt.A heating system has a condensation boiler 1, which with the help of a circulating pump 3 lying in their supply line 2 via thermostatic valves 4 to consumer 5, the are connected to the condensation boiler 1 via a return line 6. An overflow valve 7 is between the suction side and the pressure side the circulation pump 3 is hydraulically connected directly to this so that its flow direction corresponds to the flow direction of the Circulation pump 7 is opposite, that is, the overflow valve 7 is hydraulically connected anti-parallel to the circulation pump 3. When the thermostatic valve 4 is closed, it flows through the overflow valve 7 flow water so in the opposite direction to the flow, as shown by arrows in the drawing. This arrangement of the Overflow valve 7 is achieved that the amount of water in the consumer circuit variable and thus the dwell time when closing the thermostatic valves 4 becomes bigger. Since no flow water goes directly into the return line 6, there is always the return line 6 lowest possible return temperature of the water, what a economic operation of the condensation boiler 1 desired greatest possible Condensation results.

Die vorliegende Lösung verwendet eine Umwälzpumpe 3 sowie ein Ueberströmventi I 7 üblicher Ausführung. Es ist aber auch denkbar, die Umwälzpumpe 3 und das UeberströmventiI 7 als eine bauliche Einheit zu gestalten, wodurch deren Montage in der Heizungsanlage noch einfächer wird.The present solution uses a circulation pump 3 and an overflow valve I 7 usual design. However, it is also conceivable for the circulation pump 3 and the overflow valve 7 to be a structural unit design, which makes their installation in the heating system even easier will.

Durch Verwendung von Bestandteilen, d.h. einer Umwälzpumpe und eines UeberströmventiIs, die in bekannten Heizungsanlagen ohnedies vorzusehen sind, entstehen für die beschriebene Anordnung keine Mehrkosten im Vergleich mit bekannten Lösungen. Die geschilderten Massnahmen ermöglichen einen besonders wirkungsvollen Betrieb des Kondensationskessels und bringen somit bedeutende Ersparnisse an Heizungskosten. By using components i.e. a circulation pump and a Overflow valves that are to be provided in known heating systems anyway are, there are no additional costs for the arrangement described in comparison with known solutions. The measures outlined enable particularly effective operation of the condensation boiler and thus bring significant savings in heating costs.
