Definitions
- the present invention relates to a drinking or service 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 loop leading to at least one consumer.
- This ring line is connected to the supply line via inlet and outlet openings, wherein a cross-sectional constriction is provided in the supply line between the extraction and threading openings.
- the cross-sectional constriction is designed such that when flowing through the supply line in the loop line a flow is effected, due to the Venturi effect.
- the drinking or service water system may be a cold or a hot water system.
- Modern hot water systems are formed with a circulation, which ensures that hot water heated by a heater is continuously circulated in the lines leading to the consumer, so that when a water is removed from the consumer immediately hot water is discharged and microbial contamination of the system, for example by Legionella is avoided.
- the circulation prevents the cooling of hot water in the line.
- the circulation leading away from the consumer and connecting them to the heater or a boiler of the heater with a smaller diameter than the supply line is formed. The reason for this lies in the reason. det, that through the supply line as a high flow rate flow must flow through water removal, whereas in the circulation line only such a flow must be performed, which ensures a constant replacement of the hot water in the pipes of the hot water system.
- a generic drinking or service water system is for example from the DE 10 2006 017 807 known to the present applicant.
- several ring lines go from a supply line, which communicates with the interposition of a motor-driven valve with a purge line leading to a discharge point to the dirty water line. With this configuration, it is possible to flush a supply line to dissipate stagnant water there.
- the present invention makes it possible to effect a consumption flow to the corresponding consumer both via the threading opening and via the discharge opening.
- On a separate purge or return line with a smaller diameter is omitted.
- Both outgoing from the supply line and leading to a supplier ring line sections are designed as supply lines and therefore allow a supply of the required amount of hot water when removed from the consumer.
- the also attributable to the applicant DE 20 2008 003 044 Although discloses a fitting which forms a pipe section of the supply line and which causes a flow through a connected thereto ring line regardless of the direction of flow in the supply line.
- the object of this earlier application of the present applicant is not the dimensioning of the ring line sections of the loop to the effect that from the hydrodynamic point of view preferable design of the loop with a supply line with a relatively large diameter and a return line with a small diameter can be dispensed with.
- the ring line of pipe sections identical nominal diameter or nearly identical and relatively small Nominal diameter are formed. An almost identical nominal diameter is present here, if the lines differ only by a jump in the pipe dimension.
- a ring line section namely usually the outgoing from the Ausfädelö réelle pipe section, usually acts as a feed line, whereas the leading to the Einfädelö réelle ring line section can be formed with only a slightly smaller nominal diameter, since this in usually serves as a return of the flow in the loop in the supply line.
- FIG. 1 shows a schematic view of a first embodiment of a drinking and service water system with a supply line 1, which is connected to a non-illustrated transfer point for service water from a public utility network, optionally with the interposition of a device for heating the service water.

- shut-off valves 5 via which the respective ring line 2 can be separated from the supply line 1 for maintenance purposes.
- the ring line can be divided into different ring line sections. So there is a loop portion 6, which is the Ausfädelö réelle 3a downstream and leads to a remote consumer 4d.
- the flow path formed by the first ring line section 6 is the longest flow path between a consumer, a shut-off valve 5 and between the supply line 1 and the corresponding consumer 4d.
- a second and designated by reference numeral 7 Ring effetsabterrorism connects the Einfädelö réelle 3b associated shut-off valve 5 with a near load 4a.
- This second ring line section 7 forms the shortest flow path within the ring line 2 between the shut-off valve 5 and the supply line 1 and a consumer 4a.

Abstract
Description
Die vorliegende Erfindung betrifft ein Trink- oder Brauchwassersystem mit einer Übergabestelle aus einem öffentlichen Versorgungsnetz und wenigstens einer Versorgungsleitung für die Zuleitung von Wasser und wenigstens einer Ringleitung, die zu wenigstens einem Verbraucher führt. Diese Ringleitung ist über Ein- bzw. Ausfädelöffnungen an die Versorgungsleitung angeschlossen, wobei in der Versorgungsleitung zwischen der Aus- und Einfädelöffnung eine Querschnittsverengung vorgesehen ist. Die Querschnittsverengung ist derart ausgestaltet, dass bei Durchströmung der Versorgungsleitung in der Ringleitung eine Durchströmung bewirkt wird, und zwar aufgrund des Venturi-Effekts.The present invention relates to a drinking or service 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 loop leading to at least one consumer. This ring line is connected to the supply line via inlet and outlet openings, wherein a cross-sectional constriction is provided in the supply line between the extraction and threading openings. The cross-sectional constriction is designed such that when flowing through the supply line in the loop line a flow is effected, due to the Venturi effect.
Das Trink- oder Brauchwassersystem nach der vorliegenden Erfindung kann ein Kalt- oder ein Warmwassersystem sein. Moderne Warmwassersysteme werden mit einer Zirkulation ausgebildet, die dafür Sorge trägt, dass von einer Heizvorrichtung erwärmtes Brauchwasser kontinuierlich in den zu dem Verbraucher führenden Leitungen umgewälzt wird, so dass bei einer Wasserentnahme am Verbraucher umgehend Warmwasser abgegeben wird und eine Verkeimung des Systems zum Beispiel durch Legionellen vermieden wird. Die Zirkulation verhindert ein Erkalten von in der Leitung stehendem Brauchwasser. Bei Warmwasserzirkulationssystemen ist die von dem Verbraucher wegführende und diese mit der Heizvorrichtung bzw. einem Boiler der Heizvorrichtung verbindende Zirkulationsleitung mit einem kleineren Durchmesser als die Zuführleitung ausgebildet. Der Grund hierfür liegt darin begrün-. det, dass durch die Zuführleitung als Verbrauchsleitung ein hoher Volumenstrom bei Wasserentnahme hindurchfließen muss, wohingegen in der Zirkulationsleitung lediglich eine solche Strömung geführt werden muss, die einen ständigen Austausch des Warmwassers in den Leitungen des Warmwassersystems gewährleistet.The drinking or service water system according to the present invention may be a cold or a hot water system. Modern hot water systems are formed with a circulation, which ensures that hot water heated by a heater is continuously circulated in the lines leading to the consumer, so that when a water is removed from the consumer immediately hot water is discharged and microbial contamination of the system, for example by Legionella is avoided. The circulation prevents the cooling of hot water in the line. In hot water circulation systems, the circulation leading away from the consumer and connecting them to the heater or a boiler of the heater with a smaller diameter than the supply line is formed. The reason for this lies in the reason. det, that through the supply line as a high flow rate flow must flow through water removal, whereas in the circulation line only such a flow must be performed, which ensures a constant replacement of the hot water in the pipes of the hot water system.
Ein gattungsgemäßes Trink- oder Brauchwassersystem ist beispielsweise aus der
Auch bei diesem vorbekannten Trink- oder Brauchwassersystem sind die zu der Einfädelöffnung führenden Leitungsabschnitte der Ringleitung mit geringerem Durchmesser ausgebildet, so dass bei einer Strömung in der Versorgungsleitung sich jeweils eine wenn auch geringe Durchströmung in den daran angeschlossenen Ringleitungen ergibt.Also in this prior art drinking or service water system leading to the Einfädelöffnung line sections of the loop are formed with a smaller diameter, so that when there is a flow in the supply line, there is one, albeit small flow in the connected loop lines.
Davon ausgehend ist es Aufgabe der vorliegenden Erfindung, ein Trink- oder Brauchwassersystem der eingangs genannten Art anzugeben, welche sich wirtschaftlicher herstellen lässt.On this basis, it is an object of the present invention to provide a drinking or service water system of the type mentioned, which can be produced more economically.
Zur Lösung dieses Problems wird mit der vorliegenden Erfindung ein Trink- oder Brauchwassersystem mit den Merkmalen von Anspruch 1 vorgeschlagen. Dieses unterscheidet sich dadurch von dem gattungsbildenden Stand der Technik, dass ein der Ausfädelöffnung nachgeordneter und zu einem Verbraucher führender Ringleitungsabschnitt sowie ein von einem Verbraucher abgehender und zu der Einfädelöffnung führender Ringleitungsabschnitt der Ringleitung als Zuführleitung ausgelegt sind.To solve this problem, a drinking or service water system with the features of claim 1 is proposed by the present invention. This differs from the generic state of the art that one of the Ausfädelöffnung downstream and leading to a consumer ring line section and a consumer of a outgoing and leading to the threading loop line section of the loop are designed as a supply line.
Die vorliegende Erfindung schafft die Möglichkeit, sowohl über die Einfädelöffnung als auch über die Ausfädelöffnung eine Verbrauchsströmung zu dem entsprechenden Verbraucher zu bewirken. Auf eine gesonderte Spül- bzw. Rückführleitung mit geringerem Durchmesser wird verzichtet. Beide von der Versorgungsleitung abgehenden und zu einem Versorger führende Ringleitungsabschnitte sind als Zuführleitungen ausgelegt und erlauben daher eine Zufuhr der erforderlichen Brauchwassermenge bei Entnahme an dem Verbraucher. Die auf die Anmelderin ebenfalls zurückgehende
Im Gegensatz zum Stand der Technik, bei dem zwischen der Zuführleitung und der Rückführleitung wenigstens zwei Rohrleitungsdimensionssprünge verwirklicht sind und bei der die Zuführleitung beispielsweise mit DN20 relativ groß ausgestaltet ist, können mit der vorliegenden Erfindung die Ringleitung aus Rohrleitungsabschnitten identischer Nenndurchmesser oder nahezu identischer und relativ kleinem Nenndurchmesser gebildet werden. Eine nahezu identischer Nenndurchmesser liegt vorliegend vor, wenn sich die Leitungen lediglich um einen Sprung der Rohrleitungsdimension unterscheiden.In contrast to the prior art, in which at least two pipe dimension jumps are realized between the supply line and the return line and in which the supply line is made relatively large, for example with DN20, with the present invention, the ring line of pipe sections identical nominal diameter or nearly identical and relatively small Nominal diameter are formed. An almost identical nominal diameter is present here, if the lines differ only by a jump in the pipe dimension.
Durch die Wahl unterschiedlicher Nenndurchmesser kann dem Umstand Rechnung getragen werden, dass ein Ringleitungsabschnitt, nämlich üblicherweise der von der Ausfädelöffnung abgehende Rohrleitungsabschnitt, üblicherweise als Zuführleitung wirkt, wohingegen der zu der Einfädelöffnung führende Ringleitungsabschnitt mit einem nur geringfügig kleineren Nenndurchmesser ausgebildet werden kann, da dieser in der Regel als Rückführung der Strömung in der Ringleitung in die Versorgungsleitung dient.By choosing different nominal diameters, the fact can be taken into account that a ring line section, namely usually the outgoing from the Ausfädelöffnung pipe section, usually acts as a feed line, whereas the leading to the Einfädelöffnung ring line section can be formed with only a slightly smaller nominal diameter, since this in usually serves as a return of the flow in the loop in the supply line.

Das entsprechende Mengenverhältnis der einzelnen Wasserströme ändert sich mit zunehmendem Abstand von den entsprechenden Steigrohrsträngen. So wird bei Entnahme aus der Ringleitung 2.1.2 der überwiegende Anteil des Brauchwassers über den Steigrohrstrang 24 zugeführt, wogegen ein geringfügiger Anteil des Volumenstroms aus dem Steigrohrstrang 25 gespeist wird.During normal operation, the respective motor-driven shut-off valves 28 are open. In the event that, for example, a consumer is opened on the ring main 2.1.1, the supply of this consumer with service water takes place essentially via the

Bei Entnahme an einem Verbraucher der Ringleitung 2.2 erfolgt die Zufuhr von Wasser überwiegend durch den Strang 25, bei einer Entnahme durch einen Verbraucher in der Ringleitung 2.1 erfolgt die Zufuhr von Brauchwasser überwiegend über den Strang 24. Auch hier kann durch Absperren des motorgetriebenen Ventils 23 und Öffnen des Spülventils eine Spülströmung erzeugt werden. Die Spülleitung 30 hat auch bei diesem Ausführungsbeispiel einen geringeren Nenndurchmesser als der Strang 24 bzw. der Strang 25. Beide Stränge haben bei dem gezeigten Ausführungsbeispiel identische Nenndurchmesser.When removed from a consumer of the ring line 2.2, the supply of water takes place predominantly through the
