Description
Wärmetauscher für Erwärmung von Heizungs- und Brauchwasser Die Erfindung betrifft einen Wärmetauscher für gleichzeitige oder wahlweise Erwärmung von Heizungs- und Brauchwasser, wobei mit Abstand um den mittig angeordneten Warmwasserbereiter das Heizmittel in einem schraubenlinienartig gewundenen Rohr innerhalb eines . den Warmwasserbereiter seitlich umschließenden Mantelraumes für das Heizungswasser einer Sammelheizungsanlage geführt wird.Heat exchanger for heating heating and service water The invention relates to a heat exchanger for simultaneous or optional heating of heating and domestic water, with a distance around the centrally arranged water heater the heating means in a helically wound pipe within a. the Water heater laterally enclosing jacket space for the heating water one Collective heating system is performed.
Bekannt sind Wärmetauscher für die gleichzeitige oder wahlweise Erwärmung von Heizungs- und Brauchwasser, bei denen der Brauchwasserbereiter nicht vollständig vom Heizungswasser eingeschlossen ist und bei abgestellter Sammelheizungsanlage keine Umwälzung des Heizungswassers durch Wärmeauftrieb stattfindet. Dadurch kann bei großem Brauchwasserverbrauch und knapper Bemessung des Wärmetauschers die erforderliche Brauchwassertemperatur nicht gehalten werden, was sich besonders im Sommerbetrieb nachteilig auswirkt.Heat exchangers for simultaneous or optional heating are known of heating and domestic water for which the domestic water heater is not completely is enclosed by the heating water and when the collective heating system is switched off there is no circulation of the heating water due to heat buoyancy. This can in the case of high domestic water consumption and tight dimensioning of the heat exchanger, the required Domestic hot water temperature cannot be maintained, which is especially true in summer has a detrimental effect.
Der Erfindung liegt die Aufgabe zugrunde, dieses Absinken der Brauchwassertemperatur dadurch zu vermeiden, daß der Mantelraum des Wärmetauschers nach der eingangs angeführten Gattung von einem zylindrischen Außenbehälter mit einem Rücklaufstutzen in seinem Boden und einem Vorlaufstutzen in seiner Decke gebildet ist und im Außenbehälter mit Abstand von diesem und voneinander zwei gleichachsige, schraubenlinienartig gewundene, durch einen gleichachsigen, oben und unten offenen Blechzylinder voneinander getrennte Rohrschlangen angeordnet sind, wobei durch die äußere Rohrschlange zwischen Blechzylinder und Außenbehälter das Heizmittel und durch die innere Rohrschlange das Brauchwasser strömt.The invention is based on the object of this drop in the service water temperature to avoid thereby that the shell space of the heat exchanger after the mentioned Type of a cylindrical outer container with a return port in its Floor and a flow nozzle is formed in its ceiling and in the outer container at a distance from this and from each other two coaxial, helical lines sinuous from each other by an equiaxed sheet metal cylinder open at the top and bottom separate pipe coils are arranged, being through the outer pipe coil between Sheet metal cylinder and outer container the heating medium and through the inner pipe coil the domestic water flows.
In Fig. 1 ist ein Wärmetauscher nach der Erfindung im senkrechten Mittelschnitt dargestellt; Fig. 2 zeigt denselben Wärmetauscher mit einem anderen Brauchwasserbereiter im senkrechten Mittelschnitt.In Fig. 1, a heat exchanger according to the invention is in the vertical Center section shown; Fig. 2 shows the same heat exchanger with another Domestic hot water heater in the vertical center section.
Bei der Ausführung nach Fig. 1 tritt das heiße Wasser oder der Dampf als Heizmittel oben bei E in die Rohrschlange 3 ein und strömt zum Auslaß A nach unten. Hierbei wird das Heizungswasser in dem Mantelraum 7 zwischen dem zylindrischen Außenbehälter 1 und dem Blechzylinder 2, in dem die Rohrschlange 3 angeordnet ist, erwärmt. Das Heizungswasser strömt nach oben. Gleichzeitig wird das Brauchwasser in der inneren Rohrschlange 4 dadurch erwärmt, daß das Heizungswasser sich auch in dem oben und unten offenen Blechzylinder 2 ausbreitet. Das zu erwärmende Brauchwasser tritt unten bei WE in die Rohrschlange 4 ein und oben erwärmt bei WA aus. Dabei kühlt ein Teil des Heizungswassers innerhalb des Blechzylinders 2 ab und sinkt nach unten, wo es sich mit dem bei e eintretenden, abgekühlten Rücklaufwasser der Sammelheizungsanlage vermischt und zwischen dem Außenbehälter 1 und dem Blechzylinder 2 nach oben steigt. Dieser Umlauf des Heizungswassers im Wärmetauscher hängt nicht von der Sammelheizungsanlage ab.In the embodiment according to FIG. 1, the hot water or steam occurs as heating means at the top at E in the coil 3 and flows to the outlet A downwards. Here, the heating water is heated in the jacket space 7 between the cylindrical outer container 1 and the sheet metal cylinder 2 in which the pipe coil 3 is arranged. The heating water flows upwards. At the same time, the domestic water in the inner pipe coil 4 is heated in that the heating water also spreads in the sheet metal cylinder 2, which is open at the top and bottom. The domestic water to be heated enters the pipe coil 4 at the bottom at WE and warmed up at the top from WA . A part of the heating water cools down inside the sheet metal cylinder 2 and sinks to the bottom, where it mixes with the cooled return water of the collective heating system entering at e and rises up between the outer container 1 and the sheet metal cylinder 2. This circulation of the heating water in the heat exchanger does not depend on the collective heating system.
Auch bei einem Wärmetauscher nach Fig. 2 mit einem geschlossenen Behälter 6 als Brauchwasserbereiter tritt ein ähnlicher Umlauf des Heizungswassers dadurch ein, daß dieser Behälter 6 mit Abstand von dem gleichachsigen Blechzylinder 2 angeordnet ist. Neben dem äußeren Mantelraum 7 für aufsteigendes Heizungswasser ist nämlich ein gleichachsiger, ringzylindrischer Raum 8 für den Umlauf des Heizungswassers geschaffen.Even with a heat exchanger according to FIG. 2 with a closed container 6 as a domestic water heater, a similar circulation of the heating water occurs one that this container 6 is arranged at a distance from the equiaxed sheet metal cylinder 2 is. In addition to the outer jacket space 7 for rising heating water is namely an equiaxed, ring-cylindrical space 8 for the circulation of the heating water created.
