Beschreibung und Erläuterung zur Gebrauchsmusteranmeldung
„Systemtechnik zum Energiesparen für Duschtassen und Waschtische "Description and explanation of the utility model application
"System technology for energy saving for shower trays and wash basins"
Es ist bekannt zur Bereitung von Warmwasser an Duschtassen und Waschtischen Durchlauferhitzer, die mit elektrischem Strom oder Gas betrieben werden, zu verwenden. Energetisch sehr ungünstig bei elektrisch betriebenen Durchlauferhitzer ist, das elektrischer Strom als Exergie einfach in Wärme umgewandelt wird.It is well known that instantaneous water heaters that are powered by electricity or gas are used to prepare hot water for shower trays and wash basins. What is very unfavorable in terms of energy with electrically powered instantaneous water heaters is that electrical current is simply converted into heat as exergy.
Bei einem Durchfluß von ungefähr 10 Litern / Minute werden bei einer Aufheizung des Wassers von zum Beispiel 100C auf 35°C etwa 18 kW benötigt. Bei einem kontinuierlichen Wasserfluß, wie dieser bei Duschtassen oder Waschtischen in der Regel gegeben ist, verläßt das Wasser dann den Ablauf mit einer etwas geringeren Temperatur als 35°C, da das Wasser sich an den verschiedenen Bauteilen wie Rohrleitungen, Armaturen usw. abkühlt. Verläßt das Wasser über den Abfluß den Waschtisch oder die Duschtasse, so hat es bei einer Einlauftemperatur von 35°C aber sicherlich noch etwa 300C. Im weiteren Verlauf des Abflusses im Haus werden dadurch die Abflußleitungen erwärmt und die Temperatur des Wassers nimmt damit immer weiter ab und wird damit energetisch immer ärmer.With a flow rate of around 10 litres per minute, around 18 kW are required to heat the water from, for example, 10 ° C to 35°C. With a continuous water flow, as is usually the case with shower trays or wash basins, the water leaves the drain at a temperature slightly lower than 35°C, as the water cools down on the various components such as pipes, fittings, etc. When the water leaves the wash basin or shower tray via the drain, it will certainly still be around 30 ° C with an inlet temperature of 35°C. As the drain continues through the house, the drain pipes are heated up and the temperature of the water continues to decrease, making it increasingly poor in energy terms.
Der Gebrauchsmusteranmeldung liegt deshalb die Aufgabe zugrunde, möglichst viel der Energie des Abwasser zu nutzen, was optimal in unmittelbarer Nähe des Abflusses geschieht.The utility model application is therefore based on the task of using as much of the energy from the wastewater as possible, which is best done in the immediate vicinity of the drain.
Es wird deshalb vorgeschlagen einen Wärmetauscher zu verwenden der in unmittelbarer Nähe des Abflusses angeordnet wird, zum Beispiel unterhalb der Duschtasse oder unterhalb des Waschtisches, der zum einen vom noch warmen Abwasser durchflossen wird und zum anderen vom kalten Frischwasser, welches danach dem Wassererhitzer zugeführt wird. Dem Wassererhitzer kann dann Frischwasser zugeführt werden, welches zum Beispiel schon 20 oder 25°C hat. Geht man zum Beispiel von einem Gegenstromwärmetauscher aus, so kann leicht 50% Energie eingespart werden.It is therefore recommended to use a heat exchanger that is placed in the immediate vicinity of the drain, for example under the shower tray or under the wash basin, through which the still warm waste water flows on the one hand and the cold fresh water, which is then fed to the water heater, on the other. The water heater can then be fed with fresh water that is already at 20 or 25°C, for example. If you use a countercurrent heat exchanger, for example, you can easily save 50% of energy.
Wird der Einspareffekt nicht gewünscht, so läßt sich durch eine Ventilumschaltung das Frischwasser und / oder das Abwasser am Wärmetauscher vorbeiführen.If the savings effect is not desired, the fresh water and/or the waste water can be bypassed past the heat exchanger by switching the valve.
Selbstverständlich ist der Vorschlag nicht auf die vorstehend im einzelnen beschriebenen und ausgeführten Ausbildungsformen beschränkt, sondern es sind zahlreiche Abänderungen möglich ohne jedoch von dem Grundgedanken abzuweichen, Energie an Duschtassen oder Waschtischen dadurch einzusparen indem in unmittelbarer Nähe des Abflusses ein Wärmetauscher angeordnet der zum einen vom noch warmen Abwasser durchflossen wird und zum anderen vom kalten Frischwasser, wobei das Frischwasser und/oder das Abwasser auch am Wärmetauscher vorbeigeführt werden kann.Of course, the proposal is not limited to the designs described and explained in detail above, but numerous modifications are possible without deviating from the basic idea of saving energy on shower trays or wash basins by arranging a heat exchanger in the immediate vicinity of the drain through which the still warm waste water flows on the one hand and the cold fresh water on the other hand, whereby the fresh water and/or the waste water can also bypass the heat exchanger.
