Definitions

  • the present invention relates to a drinking or process water system with a transfer point from a public supply network and at least one supply line for the supply of water and at least one ring line leading to at least one consumer.
  • This ring line is connected to the supply line via threading or threading openings, a cross-sectional constriction being provided in the supply line between the threading and threading opening.
  • the cross-sectional constriction is designed in such a way that a flow is caused in the ring line when the supply line flows through, specifically because of the Venturi effect.
  • Such a drinking or process water system is from the EP 2 098 645 A1 known.
  • the drinking or process water system according to the present invention can be a cold or a hot water system.
  • Modern hot water systems are designed with a circulation that ensures that hot water heated by a heating device is continuously circulated in the lines leading to the consumer, so that when the water is drawn from the consumer, hot water is emitted immediately and the system becomes contaminated, for example, by legionella bacteria is avoided.
  • the circulation prevents the hot water in the pipe from cooling down.
  • the circulation line leading away from the consumer and connecting it to the heating device or a boiler of the heating device is designed with a smaller diameter than the supply line.
  • a generic drinking or process water system is also from, for example DE 10 2006 017 807 known to the present applicant.
  • a plurality of ring lines start from a supply line which, with the interposition of a motor-driven valve, communicates with a flushing line which leads to a discharge point to the dirty water line.
  • This configuration makes it possible to rinse a supply line in order to drain any water standing there.
  • DE 100 08 427 A1 is known a hot water supply system with a hot water tank, a circulation line connected to the hot water tank and a supply line supplying the hot water tank with fresh cold water.
  • the supply line is connected to the hot water tank by means of a circulating injector that narrows a flow cross-section, so that fresh cold water flows into the hot water tank via the circulating injector each time hot water is drawn, this cold water flow through the circulating injector due to the Bernoulli effect drawing water from the circulation line to the sequence Has.
  • the circulation injector is according to DE 100 08 427 A1 advantageous compared to a conventional circulation pump, since it is less susceptible to limescale deposits and works without external energy.
  • the present invention is intended to provide a generic drinking or process water system which can reliably avoid stagnation in the ring line.
  • the present invention proposes a drinking or process water system with the features of claim 1.
  • a volume flow leading to the supply line can be generated in the ring line, which leads to a safe and inevitable exchange of the volume in the ring line. Accordingly, stagnation can be avoided.
  • a ring line volume flow measuring device with which the volume flow in the ring line can be measured and whose volume flow measurement signal can be processed in a control device assigned to the ring line pump. Due to the narrowing of the cross-section between the opening and threading opening a pressure difference is generated in the supply line, which leads to a forced flow through the ring line when there is a flow in the supply line.
  • the cross-sectional constriction is used to achieve a certain flow in the ring line with a volume flow acting in the supply line. A fine adjustment can be made by controlling the loop line pump.
  • the volume flow at the threading opening is divided with the present invention, specifically into a ring line volume flow and a further volume flow that is not branched off into the ring line and flows in the supply line.
  • These two volume flows combine - provided no fluid is removed from the corresponding ring line via a consumer connected to it - in the threading opening.
  • the flow is also caused by the ring line pump when no fluid is withdrawn from the system at all by a consumer.
  • a supply line volume flow measuring device is provided with which the volume flow in the supply line can be measured.
  • the measurement signal of this supply line volume flow measuring device can be processed in the control device assigned to the ring line pump.
  • the ring line pump can be controlled or regulated accordingly with this preferred embodiment and an adjustment can be made between the volume flow in the supply line and the volume flow in the ring line.
  • This configuration serves in particular the purpose of controlling or regulating the volume flows on both sides between the ring line on the one hand and the supply line on the other hand on the basis of the activity of the ring line pump.
  • a ring line temperature sensor with which the water temperature in the ring line is measurable.
  • the signal of this ring line temperature sensor can be processed in the control device assigned to the ring line pump.
  • the ring line pump can accordingly be operated in a temperature-controlled manner.
  • a regulation can be stored in the control device, according to which, in particular at higher ambient temperatures, for example in a cold water system, the ring line is flushed by actuating the ring line pump. In hot summer months, for example, this ensures that fresh water is present in the ring line and that there is no contamination.
  • a supply line temperature sensor is also provided, by means of which the water temperature in the supply line can be measured and the signal of which can be processed in the control device assigned to the ring line pump.
  • This supply line temperature sensor can be provided alone or in combination with the ring line temperature sensor.
  • control device is designed such that the ring line pump can be controlled on the basis of the signal or signals supplied to the control device.
  • These signals can be the signals for the volume flows in the supply and ring line and / or the temperature values in these two lines.
  • the volume flow information can be provided, for example, by measuring a pressure difference over a given flow path, in particular via a throttle.
  • a flow measuring element can also be provided in the supply or ring line.
  • this comprises a heat source for heating the water and furthermore a circulation pump provided in the supply line, which circulates water contained in the system.
  • This circulation pump usually comprises a circulation pump control device which is connected in terms of control to the control device of the ring line pump, so that the two pumps can be operated in a coordinated manner. Accordingly, the two pumps can be operated so that their effects are mutually reinforcing.
  • Figure 1 shows a schematic view of a first embodiment of a drinking and process water system with a supply line 1, which is connected to a transfer point, not shown, for process water from a public supply network, optionally with the interposition of a device for heating the process water.
  • a device for heating the process water This can be a heat exchanger of a heater.
  • a boiler can also be integrated in a hot water network in a manner known per se.
  • the embodiment shown is a cold water network. Accordingly, the supply line 1 communicates with the interposition of a conventional water meter and a filter with the transfer point for cold water from the public supply network.
  • a multiplicity of ring lines can be connected to the supply line 1, the in Figure 1 shown section limited to the representation of a ring line 2.
  • This ring line 2 is connected to the supply line via a connection fitting 3.
  • the connection fitting 3 comprises a threading opening 3a and a threading opening 3b and a flow resistance arranged between them. This arrangement of threading opening 3b and threading opening 3a with flow resistance arranged in between is designed such that when the supply line 1 flows through the ring line 2, a flow is preferably effected according to the Venturi effect. A flow in the supply line 1 thus leads to an exchange of the water standing in the ring line 2.
  • shut-off valves 5 are located between the ring line 2 and the connection fitting 3, via which the respective ring line 2 can be separated from the supply line 1 for maintenance purposes.
  • the embodiment shown can be divided into different ring line sections.
  • the flow path formed by the first ring line section 6 is the longest flow path between a consumer, a shut-off valve 5 or between the supply line 1 and the corresponding consumer 4d.
  • a second and with reference numerals 7 marked ring line section connects the shut-off valve 5 associated with the threading opening 3b with a nearby consumer 4a.
  • This second ring line section 7 forms the shortest flow path within the ring line 2 between the shut-off valve 5 or the supply line 1 and a consumer 4a.
  • Additional ring line sections 8 connect the aforementioned consumers 4a and 4d to additional consumers 4b, 4c.
  • the first ring line section 6 is designed with a nominal diameter of DN 15.
  • the further ring line sections 8 and the second ring line section 7 are designed with a nominal diameter DN 12.
  • DN 12 the nominal diameter of DN 12
  • DN 15 the nominal size of DN 15
  • Both nominal diameters are suitable for leading a sufficient volume flow of process water to the individual consumers 4a to 4d, provided that water is drawn from the corresponding consumers 4a to 4d.
  • connection fitting 3 is preferably a connection fitting which has means for varying the passage area in the cross-sectional constriction, as a result of which the pressure difference achievable via the cross-sectional constriction can be changed dynamically, as can be traced back to the applicant DE 20 2007 009 832 U1 is disclosed, the disclosure content of which is included in this application by reference.
  • the connection fitting disclosed there is to be referred to below as “dynamic connection fitting", since this can be used to change the ratio of pressure difference to flow rate through the supply line to the effect that even with relatively small flow rates, a relatively high pressure difference is caused, which leads to a flow through the Ring line 2 leads.
  • the exemplary embodiment shown is, for example, when the process water is removed from the consumer 4a, the corresponding process water is essentially supplied via the threading opening 3b, whereas when the process 4d is removed from the consumer, the water removed there is essentially supplied via the threading opening 3a.
  • water is led to the corresponding consumer on both sides through the ring line 2 during a withdrawal.
  • Substantial volume flows through both ring line sections 6 and 7, 8 occur in particular when water is removed from consumer 4b or consumer 4c. In this case the process water is supplied both through the threading opening 3a and via the threading opening 3b.
  • the line cross-sections can be reduced compared to a conventional design, in which the feed takes place exclusively via the threading opening 3a and the threading opening 3b only serves to return the flow through the ring line 2 and therefore the return line is designed with a smaller diameter. It is also possible to design the entire ring line 3 from line sections with an identical or almost identical nominal diameter. This simplifies the assembly of the drinking water or process water system. Furthermore, assembly errors are largely excluded. Overall, the pipeline volume is lower than with conventional installation. In particular, this also results in better hygienic conditions.
  • FIG. 1 The exemplary embodiment shown has in the ring line 2 adjacent to the threading opening 3b a ring line pump 60 which is provided between this threading opening 3b and the associated check valve 5.
  • a measuring point M1 is located in the supply line 1 and the threading opening 3a in the flow direction, for measuring the volume flow in the supply line 1 and for measuring the temperature of the flowing fluid there.
  • the measuring point can also be arranged downstream in the supply line 1 of this connection fitting 3 (see M2).
  • a circulation pump 61 is provided in the supply line 1, with which the water in the system, which is hot water, circulates in the system.
  • the measurement signals for the volume flow and the temperature measured at the measuring points M1 or M2 and MR are fed to a controller, which act on the respective pumps 60 and 61, respectively.
  • FIG. 2 The opposite shows that in Figure 2
  • the exemplary embodiment shown is a schematic view of a ring line 10 which is designed as a riser pipe line and comprises two essentially parallel ring line sections which are designed as riser pipes running essentially parallel to one another and are provided, for example, in a supply shaft of a building.
  • Each of the ring line sections 11, 12 has a plurality of connections 13 for consumers (not shown), with shut-off valves 14 being provided between the consumers and the respective connections 13 close to the connections 13.

  • the connection 13.2 located above at least the main part of the flow is supplied via the threading opening 3b.
  • the measuring point M1 for measuring the temperature and the volume flow in the supply line 1 is provided upstream in the flow direction of the connection fitting 3.
  • the ring line pump 60 is located directly in the flow direction behind the threading opening 3a.
