Abstract

The method involves transferring control signals via the flow in the water pipes to a control unit (2) which controls the circulation pumps (3). A flow switch or a pressure-dependent switch on the hot water pipe picks up the control signals. Only short pulses are recognised as control signals and multiple pulses occurring within an adjustable time are ignored. An Independent claim is also included a circulation pump controller.

Description

Verfahren zur Signalübertragung und -Auswertung für bedarfsorientiert durch Anforderungssignal gesteuerte Zirkulationspumpen in zentralen Warmwasserversorgungssystemen.Process for signal transmission and evaluation for needs-based through Request signal controlled circulation pumps in central Hot water supply systems.

In Häusern mit zentraler Warmwasserversorgung werden üblicherweise Zirkulations­ leitungen und Pumpen eingebaut, die das Warmwasser an allen Zapfstellen vorbei zirkulieren lassen und so bei jedem Zapfvorgang eine sofortige Verfügbarkeit von Warmwasser garantieren.Circulations are usually used in houses with a central hot water supply Pipes and pumps installed, the hot water past all the taps let it circulate and so with every dispensing process an immediate availability of Guarantee hot water.

Die relativ hohen Energieverluste dieser Zirkulationssysteme haben dazu geführt, daß Pumpen mit Schaltuhren kombiniert werden, die nur in den Zeiten häufiger Zapfvor­ gänge die Zirkulation in Betrieb setzen. Dies reduziert zwar die Gesamtenergieverlu­ ste, erhöht aber den Wasserverbrauch durch lange Wartezeiten auf Warmwasser bei Zapfvorgängen außerhalb der Einschaltzeiten der Zirkulation. In Neubauten werden vereinzelt elektrische Schalttaster an allen Zapfstellen installiert, die per Kabelverbindung ein Anforderungssignal an ein ausschaltverzögertes Relais geben, welches die Zirkulationspumpe für kurze Zeit einschaltet. Dieses anforde­ rungsgesteuerte System hat den Nachteil, daß erheblicher Installationsaufwand erfor­ derlich ist, was bei Altbauten nachträglich i.d.R. in keinem Verhältnis zum Einsparef­ fekt steht. Außerdem kann es durch Mehrfachanforderung zu unnötig langer Pum­ penlaufzeit und so wieder zu Energieverlusten kommen.The relatively high energy losses of these circulation systems have led to the fact that Pumps can be combined with timers that only tap in times more frequent put the circulation into operation. This reduces the total energy loss but increases water consumption by long waiting times for hot water Tapping operations outside the on-times of the circulation. In new buildings, electrical switch buttons are occasionally installed at all taps, which sends a request signal to a delayed switch-off relay via cable connection which switches on the circulation pump for a short time. This request tion-controlled system has the disadvantage that considerable installation effort is required is what is usually retrospectively in old buildings disproportionate to savings is standing. In addition, multiple requests can lead to an unnecessarily long pump Pen runtime and so again come to energy losses.

Die hier beschriebene Erfindung nutzt die Warmwasserleitung selbst als Signalweg in der Weise, daß ein Strömungs- oder Druckschalter direkt am Warmwasserausgang des Boilers durch kurzes, impulsartiges Öffnen und Schließen einer Zapfstelle einen Kontakt schließt, der in einem Steuergerät als Anforderungsimpuls erkannt wird und zum Einschalten der Zirkulationspumpe für eine definierte Zeitdauer führt. Mehr­ fachanforderungen und "normale" Zapfvorgänge werden durch eine geeignete Aus­ wertelogik gefiltert und führen nicht zum Einschalten der Zirkulationspumpe. In Verbindung mit einem bewußten Umgang der Nutzer mit Warmwasser läßt sich so eine bedarfsgerechte, anforderungsgesteuerte Zirkulation mit minimalem Eingriff in das Warmwassernetz für eine beliebige Zahl angeschlossener Zapfstellen zu ver­ gleichsweise geringen Kosten realisieren und ein maximaler Einsparungseffekt von Energie und Wasser bei vertretbarem Komfort erzielen.The invention described here uses the hot water pipe itself as a signal path in the way that a flow or pressure switch directly at the hot water outlet the boiler by briefly opening and closing a tap Contact closes, which is recognized in a control unit as a request pulse and leads to switching on the circulation pump for a defined period of time. More Technical requirements and "normal" dispensing processes are achieved through a suitable off Filtered value logic and do not switch the circulation pump on. In connection with a conscious handling of the users with hot water this can be done a needs-based, requirement-controlled circulation with minimal intervention in ver the hot water network for any number of connected taps realize equally low costs and a maximum saving effect of Achieve energy and water with reasonable comfort.
