Description

Warmwasserheizung, bei der in einem Wärmeaustauscher Brauchwasser erwärmt wird. Es ist bekannt, daß Zentralheizungskessel oft zugleich für Raumheizung und Warmwasserbereitung verwandt werden, derart, - daß das warme Wasser der Zentralheizung durch einen Wärmeaustauscher hindurchfließt zwecks Erzeugung von warmem Nutzwasser für Bäder usw. Dieser Anordnung gibt man den Vorzug, damit im Winter nur eine, und zwar für die Raumheizung und Nutzwassererwärmung gemeinschaftliche Feuerstelle zu unterhalten ist. Bei dieser Vereinigung einer Feuerstelle für zwei Erwärmungszwecke kommt es jedoch bei mildem Wetter häufig vor, daß die Temperatur des Wassers für die Warmwasserheizung sehr niedrig gehalten werden soll zwecks einer generellen Regelung der Zimmerwärme, während das Nutzwasser durch diese geringe Kesselwassertemperatur nicht genügend erwärmt wird, um so mehr, als durch die Heizflächen des Wärmeaustauschers noch ein gewisser Temperaturabfall zwischen Heißwasser und geheiztem Nutzwasser ensteht, der je nach Weite der Rohrleitungsanschlüsse und etwaigen Kalkinkrustationen auf den Heizflächen, vom Nutzwasser herrührend, 20, 30 und mehr Grad betragen kann.Hot water heating in which domestic water is heated in a heat exchanger. It is known that central heating boilers are often used for space heating and hot water preparation at the same time, in such a way, - that the warm water of the central heating flows through a heat exchanger for the purpose of producing hot water for baths, etc. This arrangement is preferred so that in winter only one, a communal fireplace is to be maintained for space heating and domestic water heating. With this combination of a fireplace for two heating purposes, however, it often happens in mild weather that the temperature of the water for the warm water heating should be kept very low for the purpose of a general regulation of the room temperature, while the service water is not heated sufficiently by this low boiler water temperature more so than the heating surfaces of the heat exchanger cause a certain drop in temperature between the hot water and the heated service water, which depending on the size of the pipe connections and any lime incrustations on the heating surfaces resulting from the service water can be 20, 30 and more degrees.

Infolge dieses Übelstandes ist häufig diese gleichzeitige Benutzung eines Zentralwarmwasserheizungskessels für Wohnraumheizung und Nutzwassererwärmung fallen gelassen und sind getrennte Feuerstellen für beide Heizarten eingerichtet worden. Immerhin bietet besonders bei Anlagen geringeren Umfanges die Bedienung einer Feuerstelle für beide Heizzwecke im Winter große Vorteile für den Besitzer solcher Anlagen.As a result of this disadvantage, this simultaneous use is often a central hot water boiler for living space heating and domestic water heating dropped and separate fireplaces are set up for both types of heating been. After all, it is easy to operate, especially for systems with a smaller scope a fireplace for both heating purposes in winter has great advantages for the owner such systems.

Die nachstehend beschriebene Vorrichtung bezweckt nun, den Zentralheizungskessel durch Rohrleitungen derartig zu schalten, daß für die Beheizung der Wohnräume bei mildem Wetter die Zulauftemperatur von z. B. 5o° und weniger Grad erzeugt werden kann, während zu gleicher Zeit für die Warmwasserbereitung jede andere Heißwassertemperatur- zur Verfügung steht, selbst bis zu go ° und 95'. The device described below now aims to switch the central heating boiler through pipes in such a way that the inlet temperature of z. B. 50 ° and less degrees can be generated, while at the same time any other hot water temperature is available for hot water, even up to go ° and 95 '.

In der Zeichnung stellen dar: A Kessel für Warmwasserheizung und Warmwasserbereitung (Winter), B Kessel für Warmwasserbereitung (Sommer), C Wärmeaustauscher mit Doppelmantel für mittelbare Erwärmung des Brauchwassers, D Verteilungshahn für Rücklaufwasser, E Hauptrücklaufleitung der Warmwasserheizung, F Vorlaufleitung, G Absperrklappe für die Winterheizung, H Absperrklappe für die Sommerheizung, I Hauptrücklaufleitung zum Kessel, K Mischleitung vom Rücklauf zur Vorlaufleitung.The drawing shows: A Boiler for hot water heating and hot water preparation (Winter), B boiler for hot water preparation (summer), C heat exchanger with double jacket for indirect heating of the domestic water, D distribution tap for return water, E Main return line of the hot water heating, F flow line, G shut-off valve for winter heating, H butterfly valve for summer heating, I main return line to the boiler, K mixing line from the return to the flow line.

Die Vorrichtung besteht nun darin, daß der eRücklauf der Warmwasserheizung nicht allein durch den Kessel hindurch mit dem Vorlauf verbunden ist, sondern daß Vor- und Rücklauf außer durch den Kessel noch parallel zum Kessel unmittelbar verbunden sind, und zwar durch eine Umführung K, in welche die Rücklaufleitung der Warmwasserheizung mündet.The device is now that the eReturn of the hot water heating is not only connected to the flow through the boiler, but that Flow and return are directly connected parallel to the boiler, except through the boiler are, through a bypass K, in which the return line of the hot water heater flows out.

Durch einen an dieser Stelle eingeschraubten Dreiwegehahn kann das aus dem Rücklauf zum Kessel strömende Wasser derartig beeinflußt werden, daß nur ein Teil zum Kessel strömt, während der andere Teil unmittelbar zum Vorlauf hinfließt, so daß an dieser Stelle vom Kessel kommendes, höher erwärmtes Wasser durch das erkaltete Rücklaufwasser des Umlaufs abgekühlt wird. Derjenige Teil des hocherhitzten Heizwassers, der aus dem Kessel an die mittelbaren Heizflächen des Warmwasserbehälters C tritt, bleibt natürlich von dem kälteren Rücklaufwasser unberührt, gibt in voller Kraft wirkend seine Wärme an das Nutzwasser ab und fließt ebenfalls unbehindert zum Kessel zurück.A three-way valve screwed in at this point can do this Water flowing from the return to the boiler can be influenced in such a way that only one part flows to the boiler, while the other part flows directly to the flow, so that at this point coming from the boiler, higher heated water through the cooled Return water of the circulation is cooled. That part of the highly heated heating water which comes out of the boiler to the indirect heating surfaces of the hot water tank C, of course remains unaffected by the colder return water, gives in full force its heat is transferred to the service water and also flows unhindered to the boiler return.

Die Idee einer unmittelbaren Verbindung der Vor- mit der Rücklaufleitung ist schon bekanntgeworden; jedoch dient diese Verbindung einem andern Zweck, nämlich der Beschleunigung des Wasserumlaufs der Warmwasserheizung mittels in das Steigerohr eingeführten Dampfes. Außerdem fehlt die Regelbarkeit der unmittelbar in den Vorlauf eingeführten Rücklaufwassermenge.The idea of a direct connection between the supply and return lines has already become known; however, this connection serves another purpose, namely the acceleration of the water circulation of the hot water heating by means of the riser pipe imported steam. In addition, the controllability of the directly in the forerun is missing introduced amount of return water.
