  • Fig. 1 can be further seen that branch off from the shown secondary supply line 14 several drinking water consumers 17 and are supplied via the respective secondary supply line 14 with drinking water, in the area of each drinking water consumer 17 via a first valve 18 hot water from the respective secondary hot water line 15 and a second valve 19 cold water can be diverted from the respective secondary cooling water line 16 of the respective secondary supply line 14.
  • the region of a secondary supply line 14, however, seen in the flow direction of the drinking water behind the last consumer 17 of the respective secondary supply line 14 and thus is maximally spaced from the branch point of the respective secondary supply line 14 from the main supply line 11 is also referred to as the end or rear portion of the secondary supply line 14 ,
  • Fig. 1 which has no hot water recirculation, at least one volumetric flow sensor 20, 21 and in the region of one end of the same at least one temperature sensor 22, 23 and at least one discharge valve 24, 25 is assigned to each secondary supply line 14 in the region of a beginning thereof. So is according to Fig. 1 installed at the beginning of the secondary hot water line 15 of the flow sensor 20, in the region of the end of the same temperature sensor 22 and the drain valve 24 are installed. At the beginning of the secondary cold water line 16, the volume flow sensor 21 is installed, in the region of the end thereof, the temperature sensor 23 and the drain valve 25 are installed.
  • a measured value of at least one of the volume flow sensors 20, 21 falls below a permissible limit value
  • at least one discharge valve 24 or 25 of the respective secondary supply line 14 is opened in order to flush the respective secondary supply line 14. This applies both to the secondary hot water line 15 and to the secondary cold water line 16 of each secondary supply line 14. Accordingly, if it is determined by the measured value of the respective volume flow sensor 20, 21 that the respective water line 15, 16 of the respective secondary supply line 14 has been flushed through too low, the in the respective water pipe 15 or 16 stagnant drinking water via the respective discharge valve 24, 25 are drained, for example, in a sewer or in an operating water system of the building.
  • the respective discharge valve 24, 25 can also be opened in order to discharge drinking water from the respective secondary supply line 14.
  • the drain valve 24 of the secondary hot water line 15 of the secondary supply line 14 is opened in order to drain drinking water from the secondary hot water line 15.
  • the discharge valve 25 of the Volunteerkaltwasser admir 16 of the secondary supply line 14 can be opened to 14 derived from the Volunteerkaltwassertechnisch 16 of the Maustrangs 14 drinking water, for example, in the sewer or a service water system.
  • each secondary supply line 14 of a drinking water supply system 10 which branches off from a main supply line 11, on the one hand via two installed in the region of the beginning or front portion of the respective secondary supply line 14 volumetric flow sensors and by using two in the region of the end or the rear portion of the respective secondary supply line 14
  • Temperature sensors 22, 23 volume flows and temperatures of the drinking water in the secondary supply line 14 to check or monitor and depending on this fully automatic flushing of the respective secondary supply line 14 via the same associated drain valves 24, 25 to allow.
  • Fig. 1 shows an embodiment of a drinking water supply system 10 according to the invention without recirculation of the hot water.
  • Fig. 2 shows a variant of a drinking water supply system 10 ', in which a recirculation is realized for the hot water.
  • the main supply line 11 in addition to the main hot water line 12 and the main cold water line 13 comprises a main return line 26.
  • Each secondary supply line 14 includes in addition to the secondary hot water line 15 and secondary cold water line 16, a secondary return line 27 for hot water, according to Fig. 2 combined with the main return line 26 of the main supply line 11.
  • Fig. 3 shows an exemplary section of a drinking water supply system 10 'in the range of two secondary supply lines 14 according to Fig. 2 branching from the main supply line 11, wherein in Fig. 3 in addition, a water heater 28 is shown, from which on the one hand hot water can be supplied to the secondary supply lines 14 and in which on the other hand hot water can be returned from the secondary supply lines.
  • a water heater 28 is shown, from which on the one hand hot water can be supplied to the secondary supply lines 14 and in which on the other hand hot water can be returned from the secondary supply lines.
  • the respective control device 29 receives data via data lines 30 from the volume flow sensors 20, 21 and the temperature sensors 22, 23 of the secondary supply lines. Furthermore, the respective control device 29 transmits via data lines depending on these measured values or input data of the sensors 20, 21, 22, 23 30 control signals or control commands to the drain valves 24, 25 of the secondary supply strands 14th Limit values whose overflow or undershoot the exhaust valves 24, 25 are opened, are occupied in the control device 29.
  • the opening of the drain valves 24, 25 can be done either time-controlled or volume flow controlled. It is thus possible for the respective discharge valve 24 or 25 to be opened in a time-controlled manner for a defined period of time or volume flow-controlled for a defined volume flow when the limit value of a measured value of the sensors 20, 21, 22, 23 is exceeded or undershot.
  • This defined time span or this defined volume flow is preferably dependent on how much or by what amount the respective limit value is exceeded or undershot by the respective measured value of the respective sensor. The rinsing is done as needed and thus reduced water consumption to such an extent until the respective limit no longer violated, that is no longer exceeded or fallen below.
  • the invention provides a fully automated flushing of a drinking water supply system in order, in particular, to efficiently counteract bacterial contamination thereof.
  • a small number of modules is required in implementation of the invention.
  • a strict, demand-dependent flushing can be realized fully automatically, so that, if permissible limit values for volume flows or temperatures are not exceeded or exceeded, no flushing takes place, since this is then not necessary. In this way, the water consumption needed for flushing can be reduced over systems that flush at regular intervals.
  • Fig. 1 and 2 can be removed, the secondary hot water line 15 and the Maukaltwassertechnisch 16 and the optionally existing secondary return line 27 of a secondary supply line 14 in the region of a beginning thereof, ie adjacent to a branch point or junction of or with the main hot water pipe 12 and the main cold water pipe 13 and the possibly existing Main return line 26 of the main supply line 11, via shut-off valves 31 from the main supply line 11 can be separated.
  • Fig. 3 takes over at existing hot water recirculation a pump 32, the return of the hot water in the water heater 28th
