Definitions

  • the potable water system of EP 2 466 019 A1 further comprises a controller receiving an actual value of the hot water temperature within the hot water supply line and an actual value of the cold water temperature within the cold water supply line, wherein both temperatures are water consumer independent, and wherein the controller generates at least one control signal for preventing and/or counteracting microbiological growth within the potable water system on basis of the actual values of the hot water temperature and the cold water temperature.
  • Each water consumer 12 comprises a mixing valve 13 having a first inlet 14 connected to the hot water supply line 10, a second inlet 15 connected to the cold water supply line 11 and an outlet 16 connected to a withdrawal line 17 conducting mixed water to a point of withdrawal 18 of the respective water consumer 12.
  • Another valve 27 is preferably assigned to a by-pass line 26 branching off from the hot water supply line 10. When the valve 27 is opened, the hot water flowing through the hot water supply line 10 can bypass each water consumer 12 connected to the hot water supply line 10. There is no stagnant leg between the by-pass line 26 and the mixing valve 13 of each water consumer 12.
  • each water consumer 12 connected to the cold water supply line 11 will be flushed.
  • the above flushing is performed for a defined time period or for a defined flow volume through the withdrawal line 17 or until the actual value of the cold water temperature T2 is lower than a second threshold.
  • the second threshold is preferably lower than the first threshold.
  • the second threshold and the first threshold can also be the same. This allows an effective prevention against microbiological growth downstream of the mixing valve 23 for water consumer 12 connected to the cold water supply line 11.
  • the flushed cold water flows into a sewage 30 of the respective water consumer 12.
  • the controller 29 determines that in case of a closed mixing valve 13 the actual value of at least one mixing water temperature T1 and/or T4 is greater than a third threshold, the controller 29 generates automatically a control signal for the mixing valve 13 and a control signal for a withdrawal valve 19 of the respective water consumer 12 in order to flush and disinfect the withdrawal line 17 of the respective water consumer 12 with hot water. Also the outlet 16 of the respective mixing valve 13 becomes flushed and disinfected with hot water. For this flushing and disinfection the first inlet 14 of the respective mixing valve 13 and the withdrawal valve 19 become automatically opened.
  • the potable water system provides automatic flushing of hot water supply lines 10 and/or cold water supply lines 12 both running upstream of the mixing valves 13 and automatic flushing and disinfection of the mixing water withdrawal lines 17 running downstream of the mixing valves 13.
