Abstract

Device for switching the service-water circulating pump of a centralised hot-water supply. The circulating pump of the centralised hot-water supply is switched via a time-delay relay with a metallically isolated control circuit. It is designed for low voltage and contains the momentary-contact switches, which are located near the hot-water cocks. As long as the circulating pump is in operation, the service-water thermostat is bridged by a relay, if this cannot result in overheating of the service water.

Description

Die Erfindung betrifft eine Vorrichtung zum Schalten der Brauchwasser-Zirkulationspumpe einer zentralen Warmwasserversorgung zum Zwecke der Energie-Einsparung.The invention relates to a device for Switching the hot water circulation pump a central hot water supply for Energy saving purposes.

Die Zirkulationspumpe soll das Warmwasser vom Boiler zu den Zapfstellen pumpen. Während es früher üblich war, die Zirkulationspumpe ununterbrochen laufen zu lassen, wird sie heute meist über eine Zeitschaltuhr zumindest nachts, oft auch zu bestimmten Tageszeiten abgeschaltet. Auch der Verzicht auf die Zirkulationspumpe ist vorgeschlagen worden für maximale Einsparung an Wärme und Strom (Andreas Mihailescu, Umwelt-Sünden-Katalog, Droemer Knaur, München 1983, S. 86/87). Bei diesen Betriebsarten steht die Zirkulations­ pumpe bei Warmwasserbedarf nicht jederzeit zur Verfügung und/oder sie läuft über lange Zeiträume unnötigerweise, obwohl kein Warm­ wasser benötigt wird. Im ersten Fall kommt an den Zapfstellen statt warmes zunächst nur kaltes Wasser, was einen Wasser-Mehrverbrauch mit sich bringt, im zweiten Fall führt das ständige Aufheizen der Zirkulations-Leitungen und der Stromverbrauch der Zirkulationspumpe zu beträchtlichen Energieverlusten.The circulation pump is to take the hot water from the Pump the boiler to the tap. While it used to be the circulation pump letting it run continuously will today mostly via a timer at least at night, often at certain times of the day switched off. The waiver of the Circulation pump has been proposed for maximum savings in heat and electricity (Andreas Mihailescu, catalog of environmental sins, Droemer Knaur, Munich 1983, pp. 86/87). At The circulation is available in these operating modes do not always pump when hot water is required Available and / or it runs for a long time Periods unnecessarily, although not warm water is needed. In the first case comes at the tap instead of warm at first cold water, which is a water consumption entails, in the second case this leads constant heating of the circulation pipes and the power consumption of the circulation pump to significant energy losses.

Durch die Erfindung soll erreicht werden, daß die Zirkulationspumpe möglichst genau immer nur dann läuft, wenn Warmwasser benötigt wird. The invention is intended to achieve that the circulation pump always as accurately as possible only runs when hot water is required.  

Zur Lösung des gestellten Problems wird die Zirkulationspumpe über ein Zeitrelais betrie­ ben, das über Taster betätigt wird, die in der Nähe der Warmwasser-Zapfstellen angebracht sind. Nach der eingestellten Verzögerungs­ zeit schaltet das Zeitrelais die Zirkulations­ pumpe automatisch wieder ab. Im Stromkreis der Erregerspule des Zeitrelais liegt dessen Ruhekontakt, um Dauerbelastung auszuschließen, und die Arbeitskontakte eines Niederspannungs­ relais. Dessen Erregerspule, die Taster und die Stromversorgung, die der Haussprechanlage entnommen wird, bilden den Steuer-Stromkreis. Die Spule eines weiteren Relais ist parallel zur Zirkulationspumpe geschaltet. Seine Arbeitskontakte überbrücken den Brauchwasser­ thermostaten, solange die Zirkulationspumpe in Betrieb ist.To solve the problem posed Circulation pump operated via a timing relay ben, which is operated via buttons that in near the hot water tap are. After the set delay time the time relay switches the circulation pump off automatically. In the circuit of the Excitation coil of the timing relay is located there Quiescent contact to rule out permanent stress, and the make contacts of a low voltage relay. Its excitation coil, the buttons and the power supply that the house intercom removed, form the control circuit. The coil of another relay is parallel switched to the circulation pump. His Working contacts bridge the process water thermostats as long as the circulation pump is in operation.

Durch die Verwendung des Zeitrelais (im vor­ liegenden Fall wurde ein Treppenlicht-Automat eingebaut) steht die Zirkulationspumpe jeder­ zeit auf Knopfdruck zur Verfügung, anderer­ seits sind die Leerlaufzeiten auf ein Minimum beschränkt. Die Einsparung an Energie ist fast die gleiche, wie bei Verzicht auf die Zirkulationspumpe (bis zu 360 Liter Öl und zwischen 400 und 600 kWh Strom pro Jahr nach Mihailescu, a. a. O. S. 87), und der Wasser- Mehrverbrauch entfällt. Der galvanisch getrennte Steuer-Stromkreis für Niederspannung macht die Installation der Leitungen und Taster unproblematisch und vermeidet die Gefahren der Elektrizität in Naß-Räumen. Der Anschluß an die Haussprechanlage spart eine eigene Stromversorgung ein.By using the timing relay (in the previous horizontal case became a staircase lighting automat installed) the circulation pump stands by everyone available at the push of a button, others idle times are kept to a minimum limited. The energy saving is almost the same as if you did not Circulation pump (up to 360 liters of oil and between 400 and 600 kWh of electricity per year Mihailescu, a. a. O. S. 87), and the water No more consumption. The galvanic separate control circuit for low voltage makes the installation of the lines and Pushbuttons unproblematic and avoids that  Dangers of electricity in wet rooms. The connection to the house intercom saves own power supply.

Durch die Überbrückung des Brauchwasserthermo­ staten wird der Wärmeverlust des Boilers durch Rückfluß kalten Wassers aus der Zirkulations­ leitung und Zufluß aus dem Leitungsnetz so­ fort durch Nachheizen ausgeglichen. Diese Schaltung ist vorteilhaft, da für das Auf­ heizen des Brauchwassers bei den meisten Anlagen nur eine relativ geringe Heizleistung zur Verfügung steht. Andererseits darf dieser Teil der Schaltung nur eingebaut werden, wenn die Möglichkeit einer Überhitzung des Brauchwassers durch die Bauart der Anlage (sie arbeitet im vorliegenden Fall mit einem Kesselwasser-Brauchwasser-Wärmetauscher) ausgeschlossen ist. Die Verwendung des Zeit­ relais mit galvanisch getrenntem Steuer- Stromkreis bleibt hiervon unberührt.By bridging the hot water thermo The heat loss of the boiler is due to Reflux of cold water from the circulation pipe and inflow from the pipe network so continued to be compensated for by reheating. These Circuit is advantageous because for the on heating the domestic water in most Systems only have a relatively low heating output is available. On the other hand, this one Part of the circuit can only be installed if the possibility of overheating the Service water due to the design of the system (In the present case she works with a boiler water process water heat exchanger) is excluded. The use of time relay with galvanically isolated control The circuit remains unaffected.
