Abstract

The sub-assembly for drinking water heating in temperature ranges which prevent legionnaires bacteria, mixes no cold water to hot water, and the temperature controlling of the hot water produced in the throughflow principle is effected via a RPM controlled pump (P1) through the integration of a buffer memory (S) on the hot water side.

Description

1. Stand der Technik1. Status of technology

Die Bereitung von Warmwasser erfolgt nach dem Stand der Technik mit dem Speicherladesystem auf der WW-Seite und nach dem Durchflußsystem. Beim Speicherladesystem sind im und außerhalb des Speichers Temperaturen bei denen das Legionellenwachstum begünstigt nicht vermeidbar. Beim Durchflußsystem ist die Dimensionierung mit hoher spezifischer Leistung für die 10 Min. – Spitzenbelastung erforderlich. Darüber hinaus sind relativ komplizierte Ventilkombinationen zur Regelung der Warmwassertemperatw erforderlich.Hot water is prepared according to the state of the art with the storage charging system on the WW side and after the flow system. At the Storage charging systems are temperatures inside and outside the storage where the legionella growth favors unavoidable. At the flow system is the dimensioning with high specific performance for the 10th Min. - peak load required. About that there are also relatively complicated valve combinations for regulation the hot water temperature is required.

2. zu lösende Aufgabe2. Task to be solved

Es ist das Ziel des Gebrauchsmusters den Mängeln des Standes der Technik abzuhelfen und eine technische Lösung zu finden, dieIt is the aim of the utility model the shortcomings to remedy the state of the art and provide a technical solution find the

  • – Temperaturbereiche die das Legionellenwachstum begünstigt vermeidet- temperature ranges which favors legionella growth avoids
  • – Temperaturgrenze, ab der verstärkt Verkalkungen auftreten, nicht erreicht wird- temperature limit, from the reinforced Calcifications occur, is not achieved
  • – hohe spezifische Anschlußleistung für die 10 Min. – Spitze durch Speichernutzung reduziert wird.- height specific connected load for the 10 min. - great is reduced by memory usage.

3. Gestaltung des Gebrauchsmusters und erzielbare technische Ergebnisse3. Design of the utility model and achievable technical results

Ausgehend vom Ziel der Erfindung wurde eine Baugruppe entwickelt, die die Warmwasserbereitung in einem engem Temperaturbereich nach dem Durchflußsystem unter Einbeziehung eines Speichers ( S ) realisiert. Die Baugruppe ist gem. Anlage 1 und 2 aufgeteilt in einen Speicherladekreis auf der Heizseite und einen WW – Bereitungskreis mit Wärmetauscher ( WT2 ). Dem Speicherladekreis kann ein Dreiwegeventil ( D2 ) gem. Anlage 2, oder bei hohen Vorlauftemperaturen ein Wärmetauscher ( WT1) gem. Anlage 1 vorgeschaltet werden. Dem Speicherladekreis wird aus einer Kesselanlage ( Anlage 2 ) oder aus einer Fernwärmeanlage ( Anlage 1 ) der Heizwasserstrom zugeführt. Der Heizwasserstrom wird über ein Dreiwegeventil ( D1 ), einer drehzahlgeregelten Pumpe ( P1 ) und einem Wärmetauscher ( WT2 ) geführt, der in Verbindung mit dem Temperaturfühler ( T3 ) die Erwärmung des Trinkwassers im Durchflußsystem realisiert.Based on the aim of the invention an assembly has been developed which is used for water heating in a narrow temperature range after including the flow system a memory (S) realized. The assembly is acc. investment 1 and 2 divided into a storage tank charging circuit on the heating side and a WW preparation circuit with heat exchanger (WT2). A three-way valve (D2) acc. System 2, or a heat exchanger at high flow temperatures (WT1) acc. Attachment 1 are connected upstream. The storage charging circuit is from a boiler system (system 2) or from a district heating system (Appendix 1) the heating water flow supplied. The heating water flow is over a Three-way valve (D1), a speed-controlled pump (P1) and a heat exchanger (WT2) managed, which, in conjunction with the temperature sensor (T3), heats the Drinking water in the flow system realized.

Die Zirkulation ist entsprechend angeordnet. Aus dem Heizwasserstrom wird über eine Pumpe ( P2 ) der Speicher ( S ) im Schwachlastfall aufgeladen, so daß im Bedarfsfall die Speicherkapazität über das Dreiwegeventil ( D 1 ) abgerufen werden kann. Die Fühler ( T1 ) und ( T2 ) steuern die Pumpe ( P2 ). Ein Zuschalten der Pumpe ( P2 ) wird bei Speicherentladung durch den Strömungswächter (SW ) verhindert. Die Antriebe der Regelventile können ohne und mit Hilfsenergie eingesetzt werden.The circulation is appropriate arranged. The heating water flow is turned into a storage tank by a pump (P2) (S) charged in the light load case, so that the storage capacity over the Three-way valve (D 1) can be called up. The feelers (T1 ) and (T2) control the pump (P2). Switching on the pump (P2) is prevented by the flow switch (SW) when the storage tank is discharged. The Actuators of the control valves can can be used without and with auxiliary energy.
