Die Erfindung bezieht sich auf eine Schichtspeicheranordnung gemäß dem Oberbegriff des AnspruchesThe invention relates to a stratified storage device according to the preamble of the claim
Bei bekannten derartigen Schichtspeicheranordnungen sind meist zwei der drei Temperaturfühler in je einem Rohr gehalten, wobei die Rohre in unterschiedlichen Höhen in den Schichtspeicher hineinragen. Der dritte Temperaturfühler ist dabei meist als Anlegefühler ausgebildet und im Bereich der Warmwasserzuleitung beziehungsweise Vorlaufleitung angeordnet. Dabei ergibt sich jedoch das Problem, daß das Einschweißen dieser Rohre in die Wand des Schichtspeichers mit einem erheblichen Aufwand verbunden ist. Dabei ergibt sich auch das Problem, daß die Schweißnähte zu Spannungen führen können, die unter Umständen zu Spannungsrißkorrosionen führen können. Auch die Abdichtung von zum Beispiel eingeschraubten Rohren ist mit erheblichem Aufwand verbunden, und es ergeben sich dabei auch eine entsprechende Zahl von Problemstellen in der Schichtspeicheranordnung, an denen Undichtheiten auftreten können.In known stratified storage arrangements of this type, two of the three temperature sensors are usually held in one tube each, the tubes protruding into the stratified reservoir at different heights. The third temperature sensor is usually designed as a contact sensor and arranged in the area of the hot water supply line or flow line. The problem arises, however, that welding these tubes into the wall of the stratified storage tank involves considerable effort. The problem also arises that the weld seams can lead to stresses which, under certain circumstances, can lead to stress corrosion cracking. The sealing of, for example, screwed-in pipes is also associated with considerable effort, and there are also a corresponding number of problem areas in the stratified storage tank arrangement at which leaks can occur.
Ziel der Erfindung ist es, diese Nachteile zu vermeiden und eine Schichtspeicheranordnung der eingangs erwähnten Art vorzuschlagen, bei der mit einem Minimum an eingeschweißten Rohren ein Auslangen gefunden wird.The aim of the invention is to avoid these disadvantages and to propose a stratified storage arrangement of the type mentioned at the beginning, in which an endurance is found with a minimum of welded pipes.
Erfindungsgemäß wird dies bei einer Schichtspeicheranordnung der eingangs erwähnten Art durch die kennzeichnenden Merkmale des Anspruches 1 erreicht.According to the invention, this is achieved in a stratified storage arrangement of the type mentioned at the outset by the characterizing features of claim 1.
Durch die vorgeschlagenen Maßnahmen wird erreicht, daß die Zahl der erforderlichen, in den Schichtspeicher eingeschweißten Rohre vermindert wird. Dadurch wird auch eine Verminderung der Fehlerquellen erreicht, insbesondere durch das Schweißen verursachte Spannungen.The proposed measures ensure that the number of pipes welded into the stratified tank is reduced. This also reduces the sources of errors, in particular voltages caused by welding.
Außerdem wird durch die vorgeschlagenen Maßnahmen eine Verminderung der Wärmeleitung zur metallischen Wand des Schichtspeichers und damit eine Verminderung der Abstrahlungsverluste erreicht. Ferner gestaltet sich durch die verminderte Anzahl von Durchbrüchen in der Speicherwand auch das Emaillieren des Speichers einfacher.In addition, the proposed measures reduce the heat conduction to the metallic wall of the stratified storage tank and thus reduce the radiation losses. Furthermore, the reduced number of openings in the storage wall also makes it easier to enamel the storage.
Durch die Merkmale des Anspruches 2 ergibt sich der Vorteil einer sehr sicheren Festlegung der Lage der beiden Temperaturfühler. Dabei werden im den größeren Durchmesser aufweisenden Bereich des Rohres die Leitungen beider Temperaturfühler geführt und einer der beiden Temperaturfühler im Bereich der Verengung des Rohres, die sich im mittleren Höhenbereich des Speichers befindet, in seiner Lage gehalten. Der zweite Temperaturfühler liegt dabei im Bereich der tiefsten Stelle des Rohres, die im untersten Bereich des Speichers liegt.The features of claim 2 result in the advantage of a very reliable determination of the position of the two temperature sensors. The lines of both temperature sensors are guided in the area of the pipe with the larger diameter and one of the two temperature sensors is held in its position in the area of the constriction of the pipe, which is located in the middle height area of the store. The second temperature sensor is located in the area of the lowest point of the pipe, which is in the lowest area of the reservoir.
Durch die Merkmale des Anspruches 3 ergibt sich der Vorteil, daß in den Schichtspeicher lediglich ein Rohr eingeschweißt oder eingedichtet zu werden braucht. Der dritte Fühler im Bereich der Vorlaufleitung erfaßt im wesentlichen die Temperatur im obersten Bereich des Speichers.The features of claim 3 result in the advantage that only one tube needs to be welded or sealed into the stratified storage tank. The third sensor in the area of the flow line essentially detects the temperature in the uppermost area of the store.
Bei einer Schichtspeicheranlage gemäß dem Oberbegriff des Anspruches 4 ergibt sich durch die kennzeichnenden Merkmale des Anspruches 4 eine besonders einfache Gestaltung des Speichers, wobei lediglich ein Tauchrohr für den einzigen, in das Innere des Speichers hineinragenden Fühlers erforderlich ist. Dabei erfolgt die Erfassung der Temperatur im untersten Bereich des Speichers indirekt mittels des im Anschlußbereich der Rücklaufleitung angeordneten Temperaturfühlers und die Erfassung der Temperatur im obersten Bereich des Speichers ebenfalls indirekt mittels des in der Vorlaufleitung angeordneten Temperaturfühlers.In a stratified storage system according to the preamble of claim 4, the characterizing features of claim 4 result in a particularly simple design of the store, only one dip tube being required for the single sensor projecting into the interior of the store. In this case, the temperature in the lowermost area of the store is measured indirectly by means of the temperature sensor arranged in the connection area of the return line, and the temperature in the uppermost area of the store is also measured indirectly by means of the temperature sensor arranged in the flow line.
Die Erfindung wird nun anhand der Zeichnung näher erläutert.The invention will now be explained in more detail with reference to the drawing.
Dabei zeigen:Show:
Fig. 1 schematisch einen Schnitt durch eine Schichtspeicheranordnung und Fig. 2 einen Schnitt durch ein zwei Temperaturfühler aufnehmendes Rohr.Fig. 1 shows schematically a section through a stratified storage arrangement and Fig. 2 shows a section through a tube receiving two temperature sensors.
Gleiche Bezugszeichen bedeuten in beiden Fig. gleiche Einzelheiten.The same reference numerals mean the same details in both figures.
Wie aus der Fig. 1 zu ersehen ist, weist eine Schichtspeicheranordnung einen Schichtspeicher 20 auf, in den eine Rücklaufleitung 21 bis in dessen untersten Bereich 22 hineinreicht. In diesem Bereich 22 mündet auch eine Kaltwasserleitung 23.As can be seen from FIG. 1, a stratified storage arrangement has a stratified storage device 20, into which a return line 21 extends into its lowest region 22. A cold water pipe 23 also opens into this area 22.
In den obersten Bereich 24 mündet eine Vorlaufleitung 25, und eine Brauchwasserleitung 26 führt aus diesen Bereich 24 weg.A flow line 25 opens into the uppermost region 24, and a process water line 26 leads away from this region 24.
Temperaturfühler 2 und 3 überwachen die Temperatur im untersten Bereich 22 und im mittleren Bereich 27. Die Temperatur in der Vorlaufleitung 25 wird durch einen Temperaturfühler 1 überwacht.Temperature sensors 2 and 3 monitor the temperature in the lowest area 22 and in the middle area 27. The temperature in the flow line 25 is monitored by a temperature sensor 1.
Die Anordnung der einzelnen Temperaturfühler 1 bis 3 ist in der Fig. 1 nur schematisch angedeutet.The arrangement of the individual temperature sensors 1 to 3 is only indicated schematically in FIG. 1.
Die Vorlauf- und die Rücklaufleitung 21, 25 sind mit einem Wärmetauscher 6 verbunden, wobei in der Rücklaufleitung 21 eine Umwälzpumpe 4 angeordnet ist. Der Wärmetauscher 6 ist über Leitungen 29, 30 an einen Durchlauferhitzer angeschlossen. Dabei kann statt des im untersten Bereich 22 angeordneten Temperaturfühlers 3 ein Fühler 3' in der Rücklaufleitung 21 zwischen der Umwälzpumpe 4 und dem Wärmetauscher 6 angeordnet sein. 2The flow and return lines 21, 25 are connected to a heat exchanger 6, a circulation pump 4 being arranged in the return line 21. The heat exchanger 6 is connected via lines 29, 30 to a water heater. Instead of the temperature sensor 3 arranged in the lowermost region 22, a sensor 3 ′ can be arranged in the return line 21 between the circulation pump 4 and the heat exchanger 6. 2nd
