Abstract

The heat recovery system for hours hold use, consists of discharging all hot waste water through e.g. a coil inside a fresh water tank before it is finally discharged into the drains. The tank and coil thus form a heat exchanger. A valve and thermostat system can be used to divert cold water directly to the drains. The heat exchanger tank can be installed in a cellar. The water from a washing machine is especially useful, and new equipment can accordingly be designed for inclusion in the water heating system. The partly heated water can then be heated to a required temperature by a conventional boiler.

Description

WarmwasseraufbereiterWater heater

Die Erfindung betrifft einen Warmwasseraufbereiter, der seine Energie aus verbrauchtem warmen Schmutzwasser bezieht.The invention relates to a water heater that uses its energy draws from used warm dirty water.

Alle großen Industrienationen leiden mehr oder weniger an der Verteuerung und Verknappung aller Energiegrundstoffe und versuchen daher, die angebliche -zukünftige- Energielücke durch den Bau von Kernkraftwerken und damit Gewinnung von Atomstrom zu schließen. Die großen Industrienationen sind trotz großer Investitionen für Forschung und Technik die größten Energieverschwender; mit kostbarer Energie wird umgegangen, als stünden die entsprechenden Grundstoffe unbegrenzt zur Verfügung. bl, Erdgas, Kohle und Uranstehen uns jedoch nur noch für einige Jahrzehnte zur Verfügung. Darum heißt es, erst einmal die vorhandenen Energien richtig ausnutzen, bevor neue Kraftwerke errichtet oder geplant werden.All major industrial nations are suffering more or less from the rise in prices and shortage of all energy raw materials and are therefore trying to reduce the alleged - future - Energy gap due to the construction of nuclear power plants and thus the generation of nuclear power close. The big industrial nations are in spite of large investments in research and technology are the biggest wasters of energy; precious energy is used, as if the corresponding raw materials were available in unlimited quantities. bl, natural gas, However, coal and uranium will only be available to us for a few decades. Therefore it means to first use the available energies properly before building new power plants be built or planned.

Wenn in Deutschlahd 25 Millionen Haushalt täglich 2 kW Strom durch bessere Ausnutzung der Energien einsparen, so ergibt dieses im Jahr rd. 18 Milliarden Kilowatt.When in Deutschlahd 25 million households a day with 2 kW of electricity Saving better use of energy, this amounts to around 18 billion per year Kilowatt.

Meine Erfindung verfolgt das Ziel, mit verbrauchtem warmen Wasser kaltes Gebrauchswasser auf zuwärmen. In Millionen von Haushalten laufen täglich Waschmaschinen, Geschirrspülmaschinen, Abwaschwasser usw.. Dieses verbrauchte -warme- Schmutzwasser wird, statt wie bisher ins Siel, nun in einen Thermobehälter geleitet, in dem das Gebrauchswasser durch ein spezielles Rohr-(Röhren-)system aufgewärmt wird und für den allgemeinen Verbrauch zur Verfügung steht.My invention pursues the goal of using used warm water warm up cold service water. Run in millions of households every day Washing machines, dishwashers, dishwashing water, etc. This used -warm- Instead of being fed into the sewer as before, dirty water is now fed into a thermal container, in which the service water is warmed up through a special pipe (pipe) system and is available for general consumption.

Eine manuelle und/oder thermostatische Regulierung bewirkt, daß das kalte Schmutzwasser sofort ins Siel abgeleitet wird, so daß nur heißes bzw.A manual and / or thermostatic regulation causes the cold dirty water is immediately drained into the sewer so that only hot or

warmes Schmutzwasser in den Thermobehälter gelangt. Durch einen weiteren Thermostaten geregelt fließt das im Thermobehälter abgekühlte Schmutzwasser ebenfalls ins Siel. Ist der Thermobehälter mit heißem Wasser gefüllt, fließt nachkommenden Schmutzwasser (auch heißes) gleich ins Siel.warm dirty water gets into the thermal container. Another Thermostats The dirty water cooled in the thermal container also flows into the sewer in a controlled manner. If the thermal container is filled with hot water, dirty water flows after it (also hot) straight into the sewer.

Bei Bedarf wird das im Rohr-(Röhren-)system durch das warme Schmutzwasser aufgewirmte Frischwasser jc nach Temperatureinstellung noch durch einen Durchlauferhitzer (Boiler) nacherhitst. Es liegt auf der Hand, dar der Durchlauferhitzer (boiler) wesentlich weniger in Aktion treten muß und somit Energie eingespart wird.If necessary, this is done in the pipe (pipe) system through the warm dirty water Corrugated fresh water jc after temperature adjustment by a flow heater (Boiler) re-heating. It is obvious that the water heater (boiler) much less has to go into action and thus energy is saved.

Hein System ist installierbar sowohl in zusammenhängenden Siedlungen und Wohnblöcken als auch in einzelnen Mehr- und Einfamilienhäusern bezeihungsweise Einzelwohnungen. Der beziehungsweise die Thermobehälter kann bzw. können überall (z.B. Keller, Boden, Küche, Nische, Garten) eingebaut werden. Wohnblöcke in der Nähe von Industriegebieten könnten durch die heißen Temperaturen der Industrieabwässer mit diesem System mit Heizwärme und mit Warmwasser versorgt werden. Es ist auch möglich, kleinere Einheiten und Geräte wie zum Beispiel Waschmaschinen und Geschirrspülmaschinen selbst künftig mit diesem System auszurüsten.Hein System can be installed both in connected settlements and apartment blocks as well as in individual apartment buildings and single-family houses Single apartments. The thermal container (s) can or can be anywhere (e.g. basement, floor, kitchen, niche, garden). Blocks of flats in the Close to industrial areas could be affected by the hot temperatures of industrial wastewater can be supplied with heating and hot water with this system. It is also possible to use smaller units and appliances such as washing machines and dishwashers equip yourself with this system in the future.
