Abstract

Die Erfindung betrifft ein Verfahren zum Betreiben von Schichtladespeichern (2) für Trinkwarmwasser, insbesondere für Schichtladespeicher mit eigenem Steuergerät (12), zum hydraulischen Anschluss an einen Trinkwasserdurchlauferhitzer (1).The invention relates to a method for operating stratified charge accumulators (2) for domestic hot water, in particular for stratified storage with its own control unit (12), for the hydraulic connection to a drinking water instantaneous water heater (1).

Der Erfindung liegt die Aufgabe zu Grunde, ein Verfahren zum Betreiben eines autarken Schichtladespeichers (2) zu entwickeln, das es diesem ermöglicht, selbsttätig die an einem Trinkwasserdurchlauferhitzer (1) gewählten Temperaturvorgaben zu ermitteln und einen Beladungsprozess zu steuern, sowie auch bei Ausfall der Spannungsversorgung aus dem öffentlichen Netz einen Notbetrieb sicherzustellen.The object of the invention is to develop a method for operating a self-sufficient stratified charge accumulator (2), which enables it to automatically determine the temperature specifications selected for a drinking water instantaneous water heater (1) and to control a charging process, as well as in the event of a power failure to ensure emergency operation from the public network.

Das Verfahren ist gekennzeichnet durch ein Speicher-Steuergerät (12), das aus den von den Messfühlern (9, 10) erfassten Messsignalen selbsttätig einen am Trinkwasserdurchlauferhitzer (1) eingestellten Speicherwassertemperatur-Sollwert ermittelt und in einem Steuergeräte-internen RAM-Datenspeicher abspeichert. Anhand dieses ermittelten Speicherwassertemperatur-Sollwertes leitet es Vorgaben für das Ein- und Ausschalten der Warmwasserladepumpe (11) ab, prüft die Messsignaleingänge auf das Vorliegen der so vorgegebenen Bedingungen und schaltet die Pumpe (11) entsprechend ein und aus.The method is characterized by a memory control unit (12), which automatically determines from the measuring sensors (9, 10) measuring signals set on Trinkwasserwassersheater (1) storage water temperature setpoint and stored in a controller-internal RAM data memory. On the basis of this determined storage water temperature setpoint, it derives specifications for the switching on and off of the hot water charging pump (11), checks the measuring signal inputs for the presence of the conditions thus specified and switches the pump (11) on and off accordingly.

Das notbetriebsfähige Trinkwarmwassersystem ist gekennzeichnet durch ein in der Kaltwasseranschlussleitung (3) oder im Kaltwassereintritt (5) angeordnetes schaltbares Ventil (13), das sich bei funktionierender Spannungsversorgung in einer ersten Ventilstellung befindet und den sich bei Warmwasserzapfung einstellenden Kaltwasserzufluss in den Kaltwassereintritt (5) des Schichtladespeichers lenkt. In einer zweiten Ventilstellung, die für den Ausfall der Spannungsversorgung vorgesehen ist, wird der Kaltwasserzufluss direkt in einen Kaltwassereintritt (14) des Trinkwasserdurchlauferhitzers (1) gelenkt.

The emergency - operated domestic hot water system is characterized by a switchable valve (13) arranged in the cold water connection line (3) or cold water inlet (5), which is in a first valve position when the power supply is functioning and into the cold water inlet (5) of the cold water inlet when hot water is being drawn Stratified storage tank directs. In a second valve position, which is provided for the failure of the power supply, the cold water flow is directed directly into a cold water inlet (14) of the drinking water water heater (1).
