Vorrichtung zur Abwärmenutzung von Duschwasser, bei der das warme Duschabwasser zur Erwärmung des kühleren Frischwassers genutzt wird, mit eingebauter Reinigungsvorrichtung. Device for using waste heat from shower water, in which the warm shower waste water is used to heat the cooler fresh water, with built-in cleaning device.
Das Gehäuse und der Verdrängungskörper bestehen aus handelsüblichen Abwasserrohren. Der Wärmetauscher und die Reinigungseinrichtung wird aus Kupferrohr gefertigt.The housing and the displacement body are made of commercially available sewage pipes. The heat exchanger and the cleaning device are made of copper pipes.
Die Erfindung betrifft hier den aus Kupferrohr gefertigten Wärmetauscher,
der zur Optimierung seines Wirkungsgrades aus mehreren parallel verlaufenden, zu einer Spirale aufgedrehten
Kupferrohren besteht. Durch diese Anordnung entsteht ein besonders günstiges Verhältnis von
wärmeleitender Oberfläche, bei geringen Druckverlusten. Die Parallel verlaufenden Kupferrohre werden anschlußtechnisch
am Anfang und am Ende zu einem Rohr zusammengeführt. Der Zwischenraum der Rohrwindungen dient als Abflußkanal.
Aufgrund der Bauweise des enganliegenden Außengehäuses (5) an den Kupferrohrspiralen (7) und das sich im
Inneren des Wärmetauschers befmdliehe ebenfalls enganliegende Verdrängungsrohr
(9) wurde, um einen größeren Abflußquerschnitt zu erreichen und einer frühzeitigen Zusetzung vorzubeugen,
eine logitudinal verlaufende Vertiefung (10) im Verdrängungsrohr (9) geschaffen, durch die zusätzliche
Wassermengen abfließen können. Das in den Windungszwischenräumen (7) der Rohrspiralen (8), auf einer Kreisbahn,abfließende
warme Duschabwasser nimmt das durch den Vertiefungskanal abfließenden Wasser mit
und erzeugt eine verbesserte Durchmischung. Die Verwirbelung gewährleistet einen guten Kontakt zum Wärmetauscher
und dadurch einen effizienteren Wärmeübergang.
In die längslaufende Vertiefung (10) wurde außerdem die Reinigungsvorrichtung in Form eines Düsenrohres
eingebracht. Dieses Düsenrohr (6)hat (je nach Baugröße) 20-25 Bohrungen von ca. 1,5 mm 0 und ist so angebracht,
daß das Austretende Wasser die Abflußkanäle freispült. Die Wasserzufuhr der Reinigungsvorrichtung
wird außerhalb des Gehäusedeckels durch Absperrorgane geregelt.
Die bei diesem Verfahren zurückgewonnene Energie (bzw. Erhöhung der Eingangstemperatur) beträgt bei einer
Duschzeit von 3 min und einer Durchflußmenge von ca. 10 l/min, bereits 8-9°C und steigt nach 5 min
Duschdauer auf mehr als 10°C an, was einer errechneten Anschlußleistung von 7 kw entsprechen würde. Die
hierdurch zurückgewonnene Energie kann entweder durch Senkung des Energieaufwandes (Einsparung von
Energie) oder zur Erhöhung des Duschkomfort's (mehr warmes Wasser)
genutzt werden.The invention relates to the heat exchanger made of copper pipe, which consists of several parallel copper pipes twisted into a spiral to optimize its efficiency. This arrangement creates a particularly favorable ratio of heat-conducting surface with low pressure losses. The parallel copper pipes are connected together at the beginning and end to form a pipe. The space between the pipe turns serves as a drainage channel. Due to the design of the tight-fitting outer casing (5) on the copper pipe spirals (7) and the likewise tight-fitting displacement pipe (9) inside the heat exchanger, a longitudinally running recess (10) was created in the displacement pipe (9) through which additional water can flow away in order to achieve a larger drainage cross-section and prevent premature clogging. The warm shower waste water flowing in a circular path through the winding spaces (7) of the pipe spirals (8) takes with it the water flowing through the recessed channel and creates an improved mixing. The turbulence ensures good contact with the heat exchanger and thus a more efficient heat transfer.
The cleaning device in the form of a nozzle tube was also installed in the longitudinal recess (10). This nozzle tube (6) has (depending on the size) 20-25 holes of approx. 1.5 mm Ø and is installed in such a way that the escaping water flushes the drainage channels. The water supply to the cleaning device is regulated by shut-off devices outside the housing cover.
The energy recovered in this process (or increase in the inlet temperature) is already 8-9°C for a shower time of 3 minutes and a flow rate of approx. 10 l/min, and rises to more than 10°C after a shower time of 5 minutes, which would correspond to a calculated connected load of 7 kW. The energy recovered in this way can be used either to reduce energy consumption (saving energy) or to increase shower comfort (more warm water).
