Definitions

  • the present invention relates to a drinking water installation with a transfer point for drinking water from a drinking water supply system and a line from which a ring main leading to at least one extraction point branches off.
  • the loop is connected to the line via an inlet and is returned to the line via a return.
  • the line is laid parallel to a ring line.
  • a flow resistance element is provided between the inlet and the return, which is intended to ensure that any flow on a downstream side of the ring main in the branch not only flows through the branch but also through the ring main. This is to prevent drinking water from stagnating in the ring main for a long period of time.
  • a problem with the above-mentioned prior art is a reliable flow through the respective ring line at different volume flows within the line. It is true that there is a reliable flow through each ring if the flow resistance element causes a considerable flow resistance in the strand. In this case, however, the system pressure within the line is significantly reduced at each flow resistance element, so that the water cannot be guaranteed to flow out with the desired system pressure, ie the required volume flow at the end of the line.
  • DHW systems may need to be thermally disinfected by raising the water temperature to a disinfection temperature and circulating this very hot water in the system.
  • the accompanying problem of burns to the user the procurement of TWW during times of thermal disinfection is still unresolved in the sense of an automatic avoidance and is regularly replaced by manual safety measures.
  • Flush valves are also known nowadays, in order to bring about the desired replacement of the stagnant water with fresh water when there is no water consumption; see. DE 10 2019 201 263 A1 ; DE 10 2019 217, 903 A1 ; or. EP 1 845 207 A1 the applicant.
  • Such an exchange results in valuable drinking water being diverted into the sewage disposal network and thus wasted. This applies all the more to solutions with ring mains, since in this case the water standing in the line and the ring mains connected to it is exchanged as a whole.
  • the present invention intends to specify a drinking water installation of the type mentioned above that meets the requirements for drinking water hygiene in an improved manner while at the same time conserving water as a resource.
  • the drinking water installation according to the present invention is accordingly defined by the entirety of all pipes, fittings and apparatus located between the point of transfer of drinking water from a water supply system and the point of withdrawal of drinking water.
  • the present invention preferably focuses on those parts of the drinking water installation within the meaning of the Drinking Water Ordinance that are responsible for the distribution of drinking water in the building.
  • the drinking water extraction point i.e. the point at which the drinking water is actually removed from the pipework and released into the environment, as well as the fitting with a fitting valve leading to it, are usually not part of the drinking water installation claimed. Rather, the invention is usually not visibly realized behind the wall.
  • the features of the drinking water installation according to claim 1 are usually not visible to the user at the point of withdrawal.
  • a plurality of ring mains are usually provided one behind the other in the direction of the strand.
  • a line within the meaning of the present invention is understood in particular to be a line section running vertically and supplying a plurality of wet cells lying one above the other or comparable units provided with tapping points.
  • a strand in this sense can also be a Floor string that extends in the horizontal direction and connects several wet cells provided one behind the other on a floor.
  • Wet cells within the meaning of the invention are, in particular, wet cells in a residential building that have, for example, a toilet and/or a hand wash basin and/or a shower and/or a bathtub.
  • the drinking water installation according to the invention is preferably implemented in hotels, hospitals, old people's homes and office buildings and in connection with the wet cells provided there. Apartments that are connected via the same technology but are characterized by the fact that each apartment is occupied independently of another are also explicitly not excluded. Overall, the drinking water installation according to the invention can be installed in any type of residential or utility building in which drinking water is delivered to people.
  • the actuator of the drinking water installation according to the invention is usually an actuator which is set automatically using predetermined parameters.
  • An actuator can be formed by an actuator, i.e. a technical drive unit that converts an electrical signal from a control device into mechanical movement. This controlled mechanical movement changes the flow conditions in the drinking water installation. This involves in particular an adjustment of the through-flow or the volume flow through the ring line. The actuator thus intervenes in a controlled process.
  • the temperature of the drinking water in the line or a specific ring line can be considered as a flushing parameter.
  • a volume flow can also be considered as a flushing parameter.
  • the current flow rate is not used as the flushing parameter. Rather, the total volume that has flowed is usually of interest as the degree of the exchange of fresh drinking water from the drinking water installation due to normal supply at one or more extraction points.
  • the flow pressure at the end of the line i.e. downstream of the last ring main in the direction of flow, can also be used as a flushing parameter.
  • a pressure or pressure drop in the drinking water installation can be used to prevent flushing or to favor such flushing by the actuator automatically or, if necessary, prematurely.
  • the flow conditions in the drinking water installation that best meet the respective requirements are provided on the basis of one or more flushing parameters.
  • the actuator can act, for example, on a flow resistance element, which is installed in the line in order to change the pressure difference in the line To cause flow through an associated ring line.
  • the actuator can also be assigned directly to the corresponding ring line in order to selectively allow or prevent or essentially prevent a flow through the ring line.
  • Flow through the ring main is carried out with the aim of flushing it completely between the inlet and the return in order to exchange the volume of drinking water standing there.
  • flow conditions which essentially prevent flow through the ring line there may actually still be a slight flow through the ring line. What is essential in such flow conditions is the almost unimpeded flow through the line including the line section that extends parallel to the ring line, so that water can be removed at a withdrawal point connected to the line without any substantial loss of pressure.
  • a design that does not require a complex control device and that intervenes reliably because it is self-regulating is given by the fact that the actuator is provided, for example, by an expansion element or a component made of a shape memory bearing, which is thermally conductively coupled to the drinking water provided in the ring line in the return area .
  • the actuator is provided, for example, by an expansion element or a component made of a shape memory bearing, which is thermally conductively coupled to the drinking water provided in the ring line in the return area .
  • the expansion element is provided downstream of the last extraction point of the respective ring line in terms of heat, but far enough away from the return that thermal coupling between the water in the ring line and the water in the line essentially does not occur. Accordingly, the expansion element detects primarily, if not exclusively, the temperature of the water standing in the ring line. A warming indicates a lack of exchange of the water in the ring main. The expansion element places the actuator in such a way that flow conditions are generated in which flow through the ring line is possible.
  • the actuator is provided by a controllable actuator which is connected to a control device in terms of control. which processes a signal from a sensor as an operating parameter for the position of the actuator.
  • the actuating drive is accordingly provided as an actuator or actuator and then as a technical drive unit that converts an electrical signal into mechanical movement and thus actively intervenes in a controlled process.
  • the temperature of the water or the environment can be used as the flushing parameter.
  • a volume flow of the water in the line and/or in a ring line can be processed as a flushing parameter.
  • Time elapsed can also be a flushing parameter.
  • the pressure at a specific point in the drinking water installation can also be used as a flushing parameter.
  • Rising temperatures at a specific position within the drinking water installation in a TWK system indicate a lack of exchange of cold water with fresh water; falling temperatures lack of exchange of hot water with hot water flowing in afterwards.
  • a measured volume flow is an indication of an exchange and thus a flushing.
  • a lack of volume flow indicates an impending deterioration in drinking water hygiene. Irrespective of flow conditions, time lapse can also be considered as a parameter for purging.
  • the water pressure at a certain point of the drinking water installation can be evaluated as an indicator for the supply of drinking water.
  • the individual flushing parameters can also be evaluated in combination in the control device.
  • the corresponding flushing parameters can be evaluated in order to trigger a flushing cycle.
  • this will preferably only act in that ring line in which the conditions threaten to become critical.
  • TWK becomes too warm or TWW too cold.
  • a rinsing parameter can also be used to break through the regime of the control device, which actually wants to instruct a rinsing cycle, despite the threat of critical conditions.
  • the sensor detects an operating parameter of the drinking water present in the ring line.
  • the control device is designed in such a way that, in the event of critical conditions in the ring line, the actuator is set to adjust the flow conditions is, in which a flow through the ring line is at least substantially omitted.
  • the possibility is usually created of guiding the branch flow while bypassing a flow in the corresponding ring main, so that the pressure loss in the branch remains low.
  • the actuator adjusts the flow conditions on the basis of the specifications of the control device in such a way that flow through the corresponding ring line is possible. In any case, this position is maintained until subcritical conditions are detected again.
  • a temperature sensor is thermally conductively coupled in the ring line in the area of the return with the drinking water provided there.
  • the position of the temperature sensor essentially corresponds to the position of the expansion element according to the development already discussed above. If a temperature limit value is exceeded, the control device controls the actuator in such a way that flow through the ring line is possible. However, if the temperature detected by the temperature sensor remains within the temperature limits, flow through the ring line is at least essentially connected.
  • a temperature sensor enables precise control of conditions that require flow through and thus flushing of the ring main.
  • this can also be assigned a sensor that determines the volume flow in the corresponding ring line and/or the flow pressure or the pressure curve in the corresponding ring line.
  • the control device is preferably connected in terms of control to a flushing valve which is provided at the end of a line and through which drinking water is transferred from the drinking water installation to a waste water pipe.
  • a pressure sensor is provided, the sensor signal of which is processed in the control device in such a way that, in the event of a pressure drop attributable to the withdrawal of water at one of the withdrawal points of the drinking water installation, despite the presence of a sensor signal, which the control device uses as a Criterion for triggering a rinsing process is evaluated, the command to activate a rinsing cycle is omitted.
  • This pressure sensor detects, for example, the withdrawal of water from the drinking water installation and prevents a flushing cycle that would lead to an undesirable reduction in the volume flow at a withdrawal point due to the pressure drop in the drinking water installation as a result of the flushing.
  • the short-term safe supply of drinking water - for example, with an eye wash - clearly takes precedence over the more medium to long-term safeguarding of drinking water hygiene.
  • the control device interacts with a flow sensor that detects the volume flow during flushing.
  • the corresponding flow sensor is preferably provided in the line downstream of the last loop. This requirement follows the idea that all ring mains are used to draw water from tapping points of the ring main, whereas a flushing valve is provided at the end of the line, via which flushing can be triggered.
  • This flushing valve can also be installed in a ring line. In this case, the ring line provided with the flushing valve is not the last ring line in the sense of the development.
  • the control device concludes that a predetermined flushing volume has been reached, whereupon the valve is closed. This allows resource-saving rinsing to be carried out.
  • the control device has a memory for storing the volumes of the individual loops.
  • the controller may be configured to flush specific loops. With such a controlled flushing of a single or several specific ring lines of a line, the control device determines the duration of a flushing cycle for the corresponding partial volume of the drinking water installation based on the stored volumes, so that only the water to be exchanged is drained. It goes without saying that the volume of the at least one ring main to be flushed plus a certain safety volume is stored in the memory in order to ensure the complete exchange of water in the at least one ring main. The duration of the flushing cycle is controlled depending on the volume to be flushed.
  • the setting of the actuator can be controlled in such a way that, after replacing the stale volume in the corresponding ring main, the setting of the actuator sets flow conditions in which flow through the ring main to be flushed is not possible, whereas only for the duration of the flushing of the corresponding ring main adjusts the actuator flow conditions in which a flow through the ring main to be flushed is possible.
  • the actuators can be placed consecutively on the ring mains connected in series to the line, so that within the framework of one single rinsing cycle 'or due to the reference to drinking water from the drinking water installation said loops are each flushed individually and one after the other.
  • the control device has a memory for storing partial volume flows.
  • These partial volume flows are those partial flows that result in a line flow at a point downstream of the respective ring line when part of the line flow flows through the line section and another part of the line flow flows through the ring line.
  • the branch section is provided in parallel with the corresponding loop. If the respective ring main in the branch is assigned a flow resistance element, which also ensures a forced flow through the ring main when there is a flow in the branch, these partial volume flows are inevitable. However, these partial volume flows are also dependent on the respective flow resistances of the individual loops.
  • each individual line section is identical for each individual ring main due to the laying of identical ring main flushing fittings, as are known from the aforementioned prior art. This usually does not apply to the ring line. Because these loops have different lengths and are also laid differently.
  • the partial volume flows stored in the memory are taken into account by the control when predicting the conditions for flushing through the corresponding ring main.
  • the control device calculates a total volume which corresponds to the volume at which both line sections laid in parallel, ie the ring line and the line section, are reliably flown through and thus flushed.
  • a control device for controlling flushing processes can be one from the prior art EP 1 845 207 A1 or.
  • EP 2 365 141 A2 known drinking water installation can be used.
  • the control device can control a scavenging valve at the end of the line in a corresponding manner within the meaning of the present invention.
  • the partial volume flows can also be stored as a function of the actual volume flow, in particular for configurations of a drinking water installation in which the flow resistance changes as a function of the volume flow; compare EP 2 233 648 A1 or EP 3 617 569 A1 .
  • a volume-controlled or time-controlled flow can be controlled with this development, in which only the volume to be exchanged plus, if appropriate, a certain safety volume is exchanged and discharged to the sewage system.
  • a circulation line can also be provided, optionally with a circulation pump built into it, which connects to the line downstream of the last ring line and opens into the line upstream of the first ring line.
  • a control valve can be assigned to the ring line, which is controlled via a servomotor which communicates with the control device.
  • a regulating valve can also be provided exclusively or additionally, which is provided with an expansion element that regulates the flow in the circulation line as an actuator.
  • Such a regulating valve is preferably used when there are several circulation lines running parallel to one another which have to be hydraulically balanced with one another. This hydraulic balancing means the coordination of the different circulation lines with one another in such a way that the correct volume flow flows in each individual circulation line so that the temperature is kept at the desired level.
  • the figure 1 shows a schematic drinking water installation with several storey strands 2.1, 2.2, 2.3 and 2.4, which run horizontally and communicate via a vertical line section 4 with a transfer point 6, which - as usual - shut-off valves with water meters 8 are immediately upstream in the direction of flow.
  • the lines 2.1, 2.2, 2.3, 2.4 are provided with a plurality of ring lines 10, which are connected to the line 2 via an inlet at reference number 14 and open into line 2 at reference number 16 via a return. Details of this design are in EP 1 845 207 B1 described by the applicant. A ring line flushing fitting is also described there, which is fundamentally suitable for implementing the drinking water installation according to the invention.
  • flow resistance elements are usually provided between the inlet and the return, so that in the case of a branch flow, an annular flow is induced in the respective ring line 10 due to the pressure difference acting between the inlet 14 and the return 16 .
  • a line flow there is a parallel flow both in the ring line 10 and in a line section which is identified by reference number 12 and is laid parallel to the respective ring line 10 .
  • a flushing valve 18 is located at the downstream end of each branch 2. This flushing valve 18 connects the branch to a discharge section 20, which communicates with a waste water line 26 via a central flushing valve 22 and a free outlet 24. This sewer line 26 drains water into the municipal sewage disposal network.
  • Each ring line 10 forms at least one extraction point 28 in the form of a toilet, a hand basin, a shower or a bathtub.
  • the exemplary embodiment of the drinking water installation according to the invention implements elements known from the prior art.
  • the figure 2 shows a first variant in the form of a uniform ring line flushing fitting 30 which forms an inlet 14 and a return 16 .
  • the loop flow is identified by reference numeral 32; the strand flow with reference number 34.
  • a movable flow resistance element 36 is provided between the inlet 14 and the return 16 .
  • This flow resistance element 36 is indicated only schematically. It can be a nozzle-shaped flow resistance element 36, which causes a Venturi effect in the area of the return 16 due to the increase in speed of the branch flow 34, so that the annular line flow 32 also flows into the branch 2 due to relative suction.
  • the flow resistance element 36 is mechanically coupled to an expansion element 38 which is thermally conductively coupled to the water within the ring line 10 in the area of the return 16 .
  • the variant shown is a ring line flushing valve 30 for a cold water system TWK. If the water temperature rises in the area of the expansion element 38, the expansion of the expansion element 38 causes the flow resistance element 36 to advance in the line section 12. This increases the resistance in the line section 12. As a result, water is increasingly diverted into the ring line 10. The stale, heated water in the ring main 10 is replaced with fresh water. As a result, the expansion element becomes cooler. It contracts so that the flow resistance element 36 is retracted to its original position.
  • the variant allows a self-regulating adjustment of the flow conditions in the branch section 12 on the one hand and the ring line 10 on the other hand, so that any time there is a flow in the branch 2 downstream of the shown embodiment of the ring line flushing fitting 30, if the water is stagnant there, it is replaced when there is fresh water in the ring line 10
  • an unhindered passage of water through the branch section 12 can take place, so that the water can flow in the branch 2 without significant pressure loss.

  • the temperature sensor 42 detects the temperature of the water in the ring line 10 in the area of the return 16 . If the temperature becomes critical, so controls the controller drives the actuator 40 which advances the flow resistance element 36 into the leg section 12, thereby inducing a loop flow in the loop 10.
  • a pressure sensor 44 is implemented in the ring line flushing fitting 30 that follows. This pressure sensor 44 detects the pressure conditions in the ring line 10. If the pressure falls below a predetermined value, a ring line flow is inferred. This loop flow can result from a presetting of the movable resistance element 36 . This preset pressure difference is relatively small, but also leads to a ring line flow downstream of the corresponding ring line 10 if there is a significant volume flow within the line. If there is no such thing, which is communicated to the control device via the measured pressure value in the ring line 10, then it closes the flow resistance element 36 more, for example after a predetermined time.
  • the branch section 12 can optionally also be completely relocated, so that when there is a flow in the branch 2 downstream of the corresponding ring line 10, a ring line flow is reliably induced in the latter.

  • a volume flow sensor 46 is installed in the ring line 10 near the return 16. This volume flow sensor 46 detects an actual ring line flow and reports its presence or absence to the control device, so that the control device places the actuator 40 on the movable flow resistance element 36 in order to cause flow through the ring line 10 .
  • the last ring line 10 shown is flowed through either when water is removed via said ring line, or when the flushing valve 18 installed at the end of the rod 2 is activated.
  • a volume flow sensor 48 and/or a temperature sensor 50 is upstream of the flushing valve 18 in the direction of flow, which initiates a flushing cycle by activating the flushing valve 18 either after a volume flow has taken place, which is diverted into the waste water pipe 26, or because the water temperature has fallen below a predetermined which indicates the exchange of line 2 and the ring mains 10 connected to it with fresh water.
  • a pressure sensor 51 can also be installed in the end area of the strand. The signal from such a sensor can prevent flushing if the pressure determined in the end of the strand is too low. Since no extraction point is provided here, a low pressure is taken as an indication of insufficient flow pressure at a downstream point where water is extracted. If the measured pressure is too low, it is concluded that the flow pressure at the water extraction point is insufficient.
  • an optional circulation line 60 is drawn in, which is provided with a circulation pump 62 .
