Abstract

Die Erfindung betrifft unter anderem ein Verfahren zur Kalt- und Warmwasserbereitstellung in einem Wasserversorgungssystem, insbesondere einem Trinkwasserversorgungssystem, bei dem
- an mindestens einer Zapfstelle (Z1 - Z3) bereitzustellendes Kaltwasser (KW) über eine Kaltwasserzirkulation (KWZ) vorgehalten wird, in die über einen Frischwasseranschluss (3A) frisches Kaltwasser (KW) eingespeist werden kann, und
- an der mindestens einen Zapfstelle (Z1 - Z3) bereitzustellendes Warmwasser (WW) über eine Warmwasserzirkulation (WWZ) vorgehalten wird. Erfindungsgemäß ist vorgesehen, die Kaltwasserzirkulation (KWZ) mit der Warmwasserzirkulation (WWZ) derart zu verbinden, dass bei einer Entnahme von Warmwasser (WW) an der mindestens einen Zapfstelle (Z1 - Z3) Kaltwasser (KW) aus der Kaltwasserzirkulation (KWZ) in die Warmwasserzirkulation (WWZ) eingespeist und gleichzeitig frisches Kaltwasser (KW) in die Kaltwasserzirkulation (KWZ) aus dem Frischwasseranschluss (3A) nachgeführt wird, so dass hierdurch die Temperatur des in der Kaltwasserzirkulation (KWZ) befindlichen Kaltwassers (KW) abgesenkt wird.The invention relates inter alia to a method for providing cold and hot water in a water supply system, in particular a drinking water supply system, in which
- cold water (KW) to be provided at at least one tap (Z1 - Z3) is kept in circulation via cold water circulation (KWZ) into which fresh cold water (KW) can be fed via a fresh water connection (3A), and
- Provided at the at least one tap (Z1 - Z3) to be provided hot water (WW) via a hot water circulation (WWZ). According to the invention, the cold water circulation (KWZ) with the hot water circulation (WWZ) to connect such that at a withdrawal of hot water (WW) at the at least one tap (Z1 - Z3) cold water (KW) from the cold water circulation (KWZ) in the Hot water circulation (WWZ) fed and simultaneously fresh cold water (KW) in the cold water circulation (KWZ) from the fresh water connection (3A) is tracked, so that thereby the temperature of the chilled water (KWZ) chilled water (KW) is lowered.

Gemäß einem weiteren Aspekt ist in einem Kaltwasserrücklauf (3b) einer Kaltwasserzirkulation (KWZ) eine Ablasseinrichtung (8) vorgesehen, über die Kaltwasser (KW) aus der Kaltwasserzirkulation (KWZ) abgelassen wird, wenn eine gemessene Temperatur für in dem Kaltwasserrücklauf (3b) befindliches Kaltwasser (KW) einen vorgegebenen Temperaturschwellwert überschritten hat.

Figure imgaf001
According to a further aspect, in a cold water return (3b) of a cold water circulation (KWZ) a discharge device (8) is provided, is discharged via the cold water (KW) from the cold water circulation (KWZ) when a measured temperature for in the cold water return (3b) befindliches Cold water (KW) has exceeded a predetermined temperature threshold.
