Description

Zweck der Erfindung:Purpose of the invention:

Die im Duschwasser nach Benutzung noch enthaltene Wärmemenge, welche normalerweise als Abwasser in den Kanal geführt wird, soll in einem Gegenstromwärmetauscher das neu zu erwärmende Duschwasser vorwärmen. Außerdem soll durch eine entsprechende Volumenauslegung des Pufferbehälters mit Durchlauferhitzer auf Einbau eines Boilers, Speichers, etc. verzichtet werden können. Die Stillstandsverluste (Betriebsbereitschaftsverluste) bisher eingesetzter Wärmeerzeuger sollen so weitgehend vermieden werden.The amount of heat still contained in the shower water after use, which normally discharged into the sewer, is said to be in one Counterflow heat exchanger preheat the shower water to be heated. In addition, the volume of the buffer tank should be designed accordingly with instantaneous water heater for installation of a boiler, storage tank, etc. can be dispensed with. The standstill losses (Operational losses) previously used heat generators should largely avoided.

Stand der Technik:State of the art:

Es wird mittels eines Boilers, Speichers, etc. über einen Wärmeerzeuger Duschwasser (Brauchwasser) produziert.It is by means of a boiler, storage, etc. via a heat generator Shower water (domestic water) is produced.

Nach dem Duschvorgang verläßt dieses Wasser das System, um als Abwasser dem Kanalnetz zugeführt zu werden. Die im Abwasser enthaltene Wärme geht verloren. Dieses ist ein entscheidener Nachteil der o. a. Systeme. Ein weiterer Nachteil ist, daß außerhalb der Heizperiode ( Sommerbetrieb ) relativ hohe Betriebsbereitschaftsverluste in Kauf genommen werden müssen.After the shower process, this water leaves the system to act as wastewater to be fed to the sewer network. The heat contained in the wastewater is lost. This is a major disadvantage of the above. Systems. Another disadvantage is that outside the heating season (summer operation) relatively high operational losses have to be accepted.

Gestellte technische Aufgabe:Technical task:

Als erstes Ziel die Energieeinsparung, eine Energieeinsparung durch Einsatz eines Gegenstromwärmetauschers, welcher mit der im Abwasser enthaltenen Wärme das neu aufzuheizende Duschwasser vorwärmt. The first goal is energy saving, energy saving through commitment a counterflow heat exchanger, which with the contained in the waste water Preheat the newly heated shower water.  

Weitere Ziele:Other goals:

Vermeidung von Betriebsbereitschaftsverlusten im Sommerbetrieb, d.h. Heizkessel als Wärmeerzeuger können im Sommer abgeschaltet werden.Avoidance of operational readiness losses in the Summer operation, i.e. Boilers can be used as heat generators in summer be switched off.

Außerdem soll die Duschwassermenge durch Einsatz eines Durchflußmengenbegrenzers reduziert werden. Hierdurch werden die Energie- Wasser- und Abwasserkosten vermindert.In addition, the amount of shower water should be by using a Flow limiter can be reduced. As a result, the energy Water and wastewater costs reduced.

Funktionsbeschreibung:Function description:

Das beim Duschvorgang abfließende, noch warme Abwasser sammelt sich am Boden der Duschwanne (A) und passiert die Abflußöffnung (1). Sodann läuft das Abwasser durch einen Filter (2). Dieser Filter soll gewährleisten, daß der Gegenstromwärmetauscher (4) nicht mit Seifenresten, Haaren, etc. verunreinigt wird. Die nach dem Filter installierte Förderpumpe (3) mit Schwimmerschalter soll einerseits den Widerstand des gesamten Aggregates überwinden, sowie sicherstellen, daß bei höhergelegenen Abläufen der sichere Abfluß des Abwassers gewährleistet ist.The still warm waste water that flows off during the shower process collects at the bottom of the shower tray ( A ) and passes through the drain opening ( 1 ). The waste water then runs through a filter ( 2 ). This filter is intended to ensure that the counterflow heat exchanger ( 4 ) is not contaminated with soap residues, hair, etc. The feed pump ( 3 ) with float switch installed after the filter is intended to overcome the resistance of the entire unit and to ensure that the drainage of the waste water is guaranteed with higher-level drains.

Im Gegenstromwärmetauscher (4) wird dem Abwasser - so weit wie möglich - die Wärme entzogen, indem das eintretende Kaltwasser (6) vorgewärmt wird.In the counterflow heat exchanger ( 4 ), the heat is extracted from the wastewater as much as possible by preheating the incoming cold water ( 6 ).

Dieses vorgewärmte Wasser wird sodann im Pufferbehälter mit eingebautem Durchlauferhitzer (7) elektrisch auf die erforderliche Endtemperatur aufgeheizt.This preheated water is then heated electrically to the required final temperature in the buffer tank with built-in instantaneous water heater ( 7 ).

Auf die gesonderte Zeichnung des Pufferspeichers mit Durchlauferhitzer (7) sei an dieser Stelle hingewiesen. At this point, reference is made to the separate drawing of the buffer tank with instantaneous water heater ( 7 ).

Die Regelung der erforderlichen Temperatur geschieht durch einen Regelthermostaten in der elektrischen Stromzuführung zum Durchlauferhitzer (Fig. 7a).The regulation of the required temperature is done by a control thermostat in the electrical power supply to the water heater ( Fig. 7a).

Der weitere Weg des nun erwärmten Duschwassers führt durch einen thermostatischen Brauchwassermischer (9).The further path of the now heated shower water leads through a thermostatic service water mixer ( 9 ).

Durch die Verbindung des Kaltwassereintritts (6 und 10) zum thermostatischen Brauchwassermischer (9) wird eine Übertemperatur sowie Verbrühung beim Duschen vermieden. Ein Durchflußmengenbegrenzer (12) reduziert abschließend die Wassermenge und somit den Energie- und Wasserverbrauch.By connecting the cold water inlet ( 6 and 10 ) to the thermostatic hot water mixer ( 9 ), overtemperature and scalding when showering are avoided. A flow limiter ( 12 ) finally reduces the amount of water and thus the energy and water consumption.

Ausführungsbeispiele:Examples:

Das energiesparende Duschsystem ist anwendbar in allen Fällen eines Bedarfs von Duschvorrichtungen. Im Neubau von vornherein durch konstruktive Berücksichtigung bei der Planung. Im Altbau durch Änderung der Duschanlage mit einer flachen oder stufenartig geformten Brausewanne (Duschwanne).The energy-saving shower system can be used in all cases Need shower fixtures. In the new building from the outset through constructive Consideration when planning. In the old building through changes the shower system with a flat or step-shaped shower tray (Shower tray).

Weitere Anwendungsmöglichkeiten:
Saunen,
Hotelzimmer,
Sportstätten,
Schulen, etc.
Other possible uses:
Saunas,
Hotel room,
Sports facilities,
Schools, etc.

Besonders hingewiesen sei an dieser Stelle auf die großen Betriebsbereitschaftverluste der großen Heizkessel während des Sommerbetriebes in Schulen, etc. At this point, particular attention should be drawn to the large operational losses of the large boilers during summer operation in Schools, etc.
