Description
Die Erfindung betrifft einen Brauchwasser-Durchflusserwärmer zur indirekten Erwärmung von Brauchwasser mittels Plattenwärmetauscher.The The invention relates to a service water flow heater for indirect heating of Domestic hot water by means of plate heat exchanger.
Solche Vorrichtungen sind in der Technik bekannt und werden von diversen Herstellern angeboten.Such Devices are known in the art and are of various types Offered to manufacturers.
Um bei einer solchen Vorrichtung – in seiner Temperatur geregeltes – Brauchwasser in Trinkwasserqualität entnehmen zu können, ist der Heizungspufferspeicher über eine steuerbare Umwälzpumpe mit der Primärseite des Plattenwärmetauscher verbunden. Sekundärseitig steht der Wärmetauscher mit einem Anschluss für unter Druck stehendes frisches (kaltes) Wasser in ständig offener Verbindung. Die Ausgangsseite der Sekundärseite des Wärmetauschers dient der Entnahme des erwärmten Brauchwassers mit Trinkwasserqualität. Im Stand der Technik übernimmt oft eine Regelung die Aufgabe, die Temperatur des abgegebenen Trinkwassers zu regeln, welche auf das Signal eines Strömungsmelders anspricht und die Umwälzpumpe im Primärkreis des Wärmetauschers in Abhängigkeit von einem Brauchwasser-Sollwert und in Abhängigkeit der Temperatur des abgegebenen Trinkwassers einschaltet, ausschaltet oder ihre volumetrische Leistung regelt.Around in such a device - in its temperature regulated - process water in drinking water quality to be able to remove the heating buffer is over a controllable circulation pump with the primary side the plate heat exchanger connected. On the secondary side is the heat exchanger with a connection for pressurized fresh (cold) water in constantly open Connection. The output side of the secondary side of the heat exchanger serves to remove the heated service water with drinking water quality. In the prior art takes over often a regulation the task, the temperature of the dispensed drinking water to regulate, which responds to the signal of a flow detector and the circulation pump in the primary circuit of heat exchanger dependent on from a dhw setpoint and depending on the temperature of the turned off drinking water, turns off or their volumetric Performance regulates.
Aufgrund von physikalischen Gegebenheiten ergeben sich unterschiedliche Vor- und Nachteile je nach Anordnung und Einbaulage der Komponenten der beschriebenen Vorrichtungen. Besonderes Augenmerk ist dabei auf den Plattenwärmetauscher und seine Orientierung gegenüber der Achse oder Richtung der Schwerkraft zu richten. Es wird von einem Plattenwärmetauscher gängiger Bauart mit seinen Abmessungen L × B × H, wie er in den meisten Brauchwasser-Durchflusserwärmern mit Plattenwärmetauscher eingesetzt wird, ausgegangen.by virtue of physical conditions result in different and disadvantages depending on the arrangement and installation position of the components described devices. Particular attention is paid to this the plate heat exchanger and his orientation towards to direct the axis or direction of gravity. It is from a plate heat exchanger common Type with its dimensions L × W × H, as used in most domestic water flow heaters Plate heat exchanger used is assumed.
Bei waagerechter Einbaulage (L senkrecht zur Schwerkraft) zeigte sich in der Vergangenheit, dass die Plattenwärmetauscher zum Verkalken neigen, außerdem tritt häufig Korrosion auf.at horizontal installation position (L perpendicular to gravity) showed up in the past, that the plate heat exchangers tend to calcify, Furthermore occurs frequently Corrosion on.
Deshalb ist man in der nahen Vergangenheit dazu übergegangen, den Wärmetauscher senkrecht (L liegt auf der oder parallel zur Schwerkraftachse) anzuordnen und zwar so, dass der kalte Trinkwassereintritt oben angeschlossen wird. Es zeigte sich, dass die Probleme mit Korrosion und Verkalkung damit deutlich zurückgehen, es tauchte jedoch ein neues Problem auf.Therefore In the near past one has gone over to the heat exchanger perpendicular (L is on or parallel to the axis of gravity) to arrange in such a way that the cold drinking water entrance connected at the top becomes. It turned out that the problems with corrosion and calcification to go back significantly, However, there was a new problem.
Bei dieser Anordnung befindet sich der Warmwasserausgang nahe dem tiefsten Punkt des Plattenwärmetauschers. Wird der Warmwasserbedarf durch Schließen des Warmwasserhahnes abgemeldet, führt das auch zum Ausschalten der Zirkulationspumpe im Heizungspufferkreis. Das Wasser im Plattenwärmetauscher kommt zunächst zum Stillstand. Dann setzt aber unmittelbar eine Eigenbewegung des Wassers im Wärmetauscher und den angeschlossenen Rohren ein, verursacht durch die temperaturabhängige Dichte des Wassers. Das schwere, kältere Wasser „fällt" im Wärmetauscher nach unten und strömt in die unten angeschlossenen Rohre. Dieser Vorgang findet relativ schnell statt, schon nach ca. 30 sec. kühlen der Wärmetauscher und das angeschlossene Trinkwarmwasserrohr um 10° oder mehr ab.at This arrangement is the hot water outlet near the deepest Point of the plate heat exchanger. If the hot water requirement is canceled by closing the hot water tap, does that also for switching off the circulation pump in the heating buffer circuit. The water in the plate heat exchanger come first to a halt. But then immediately sets a proper movement of the Water in the heat exchanger and the connected pipes, caused by the temperature-dependent density of the water. The heavy, colder one Water "falls" in the heat exchanger down and flows in the pipes connected below. This process is relative quickly, after only 30 sec cool the heat exchanger and the connected DHW pipe at 10 ° or more off.
Wird nun der Warmwasserhahn wieder geöffnet, so tritt an der Zapfstelle für einige Sekunden deutlich kälteres Wasser aus. Dieser Effekt kann für den Verbraucher sehr unangenehm sein.Becomes now the hot water tap reopened, so occurs at the tapping point for a few seconds much colder Water off. This effect can be for the Consumers are very uncomfortable.
Der Erfindung liegt die Aufgabe zugrunde, den Plattenwärmetauscher so zu gestalten, dass sich die Abkühlung des Trinkwarmwassers bei kurzzeitigem Abschalten des Warmwasserbedarfs verringert, ohne die positiven Auswirkungen auf Verkalkung und Korrosionsverhalten eines senkrechten Tauschers zu verlieren.Of the Invention is based on the object, the plate heat exchanger to be designed so that the cooling of the drinking water reduced for short-term shutdown of hot water demand, without the positive effects on calcification and corrosion behavior to lose a vertical exchanger.
Diese Aufgabe wird mit dem Brauchwasser-Durchflusserwärmer nach Anspruch 1 oder Anspruch 2 erfüllt. Durch Drehen des Plattenwärmetauschers aus der Senkrechten um einen Winkel kleiner als 45° können die physikalischen Bedingungen der Anordnung so verändert werden, dass bei einer Unterbrechung des Zapfvorganges die thermisch bedingte Eigenbewegung des Wassers im Wärmetauscher und in den Rohren weniger stark zu einer Abkühlung des Trinkwarmwasser-Auslasses führt, als bei einem senkrechten Wärmetauscher. Man achtet darauf, den Trinkwasserstrang auf die Seite des Tauschers zu legen, deren unterer Anschluss der höhere von den beiden unteren Anschlüssen ist.These Task is with the hot water flow heater according to claim 1 or claim 2 fulfilled. By turning the plate heat exchanger from the vertical by an angle smaller than 45 °, the physical conditions of the arrangement are changed so that at a Interruption of the tapping process the thermally induced proper motion of water in the heat exchanger and in the pipes less strongly to a cooling of the hot water outlet leads, as with a vertical heat exchanger. Make sure you put the drinking water line on the side of the exchanger whose lower terminal is the higher of the two lower ones connections is.

Dieses ist hier mit offenbart, aber nicht als Verfahren beansprucht.The The invention (also disclosed) also covers a method involving generation of service water in the installation position of the exchanger according to claim 1 or claim 2 represents. This is revealed here with, but not claimed as a method.
