Description
Die Erfindung betrifft einen Warmwasserbereiter zum insbesondere vertikalen Einbau in einer Gebäudewand oder einer Wandvorsatzverkleidung, mit den Merkmalen des Oberbegriffs des Anspruchs 1. Die Erfindung betrifft weiters ein Warmwasserbereitungsmodul zum Einbau in einer Gebäudewand.The invention relates to a water heater for particular vertical installation in a building wall or a wall cladding, with the features of the preamble of claim 1. The invention further relates to a hot water preparation module for installation in a building wall.
Aus dem Stand der Technik sind seit langem Warmwasserbereiter in verschiedenen Ausführungen bekannt. So stellt beispielsweise
Die bekannten Nachteile derartiger Warmwasserbereiter, dass sie einen großen Platzbedarf haben und nur sichtbar und somit störend in einem Raum montiert werden können, sowie dass die Fertigung der beiden gewölbten Böden als Rohrabschlüsse des zylindrischen Rohrs aufwendig ist, werden auch von der in
Weiters ist von Nachteil bei Warmwasserbereitern, bei denen eine einzige, in Einbaulage vertikale oder horizontale Speicherkammer für das Warmwasser vorgesehen ist, dass es während des Erhitzens des Wasservolumens aufgrund der Größe der einzelnen Speicherkammer sowie aufgrund von Zonen in der Speicherkammer, die von der Heizquelle weiter entfernt liegen, zu einer ungleichmäßigen Erwärmung des Wasservolumens kommt. Bis das gesamte in der Speicherkammer mit einem Fassungsvolumen von üblicherweise über 100 Liter vorhandene Brauchwasser gleichmäßig auf ein vorgegebenes Temperaturniveau erwärmt ist, ist aufgrund der langen Aufheizdauer somit ein relativ hoher Energieeintrag erforderlich. Derartige Warmwasserbereiter werden deshalb meist während der Nachtstunden aufgeheizt.Furthermore, it is disadvantageous in water heaters, in which a single, vertical or horizontal storage chamber is provided for the hot water, that during the heating of the water volume due to the size of the individual storage chamber and due to zones in the storage chamber, the further from the heat source lie away, causing an uneven heating of the water volume. Until the entire in the storage chamber with a capacity of usually more than 100 liters existing hot water is uniformly heated to a predetermined temperature level, thus a relatively high energy input is required due to the long heating time. Such water heaters are therefore usually heated during the night hours.
Aus
Die vorliegende Erfindung stellt sich daher die Aufgabe, für einen Warmwasserbereiter der eingangs genannten Art die aus dem Stand der Technik bekannten Nachteile zu vermeiden, und dazu eine Vorrichtung zu schaffen, die aufgrund ihrer Abmaße sowohl im kommunalen Wohnbau, als auch beispielsweise in Hotels, Krankenhäusern oder in Gewerbeobjekten eingesetzt werden kann, die in Unterputzausführung in Trockenbauwänden, in Vorsatzverkleidungen bzw. in Mauernischen einbaubar ist, einfach in der Herstellung ist und die mit möglichst geringen Wärmeverlusten effizient und rasch die jeweils erforderlichen Mengen an Brauchwasser erwärmt. Insbesondere sollte der Warmwasserbereiter schnell und gleichmäßig aufheizbar sein.The present invention therefore has as its object to avoid the disadvantages known from the prior art for a water heater of the type mentioned, and to provide a device that due to their dimensions both in municipal housing, and for example in hotels, hospitals or can be used in commercial properties that can be installed flush-mounted in drywall, in cladding or in wall niches, is easy to manufacture and heats efficiently and quickly with the lowest possible heat losses each required amounts of hot water. In particular, the water heater should be heated quickly and evenly.
Diese Aufgabe wird bei einem Warmwasserbereiter gemäß dem Oberbegriff des Anspruchs 1 mit den Merkmalen des kennzeichnenden Teiles des Anspruchs 1 gelöst. Die Unteransprüche betreffen weitere vorteilhafte Ausgestaltungen der Erfindung.This object is achieved in a water heater according to the preamble of claim 1 with the features of the characterizing part of claim 1. The subclaims relate to further advantageous embodiments of the invention.
In einer vorteilhaften Ausgestaltungsform sind bei einem erfindungsgemäßen Warmwasserbereiter zum insbesondere vertikalen Einbau in einer Gebäudewand, umfassend ein einen geschlossenen Speicher-Innenraum bildendes Gehäuse, wobei der Speicher-Innenraum durch zumindest zwei nebeneinander angeordnete Rohrabschnitte mit vorzugsweise jeweils zueinander parallelen Längsachsen, die an ihren beiden Rohrenden durch Sammelrohre, deren Längsachsen im Winkel, vorzugsweise in rechten Winkel, zu den Rohrabschnitten stehen, miteinander verbunden sind, gebildet ist, die Rohrabschnitte sowie die Sammelrohre mit demselben Innendurchmesser ausgeführt.In an advantageous embodiment, in a water heater according to the invention for vertical installation in particular in a building wall, comprising a housing forming a closed memory interior, wherein the memory interior by at least two juxtaposed pipe sections with preferably mutually parallel longitudinal axes, at its two pipe ends by collecting tubes whose longitudinal axes are at an angle, preferably at right angles, to the pipe sections, are connected to each other, is formed, the pipe sections and the manifolds executed with the same inner diameter.
Ausführungen, in denen die Längsachsen der Sammelrohre beispielsweise in unterschiedlichen, von einem rechten Winkel abweichenden Winkel auf einen oder mehrere der nebeneinander angeordneten Rohrabschnitte stehen, sind ebenfalls angedacht. Damit ist es beispielsweise möglich, auch schräg zulaufende Wände im Bereich eines Stiegenhauses für den Einbau eines erfindungsgemäßen Warmwasserbereiters zu nutzen. Die Verwendung von Rohren mit demselben Innendurchmesser für die Fertigung der Rohrabschnitte sowie der Sammelrohre ist nicht nur kostengünstiger, sondern erleichtert auch die Konstruktion der Gehrungsausschnitte bzw. Übergänge zwischen den Rohrabschnitten und den Sammelrohren. Warmwasserbereiter, die mit Rohren mit demselben Rohrquerschnitt, d.h. mit jeweils demselben Innendurchmesser, demselben Außendurchmesser sowie derselben Wandstärke, gefertigt sind, sind von der Erfindung mit umfasst.Embodiments in which the longitudinal axes of the headers are, for example, at different angles deviating from a right angle to one or more of the juxtaposed pipe sections are also contemplated. This makes it possible, for example, to use even diagonally tapered walls in the area of a staircase for the installation of a water heater according to the invention. The use of tubes with the same inner diameter for the production of the pipe sections and the manifolds is not only cheaper, but also facilitates the construction of Miter cuts or transitions between the pipe sections and the headers. Water heaters, with pipes with the same pipe cross-section, ie are each made with the same inner diameter, the same outer diameter and the same wall thickness, are included in the invention.
Auch Ausführungen eines erfindungsgemäßen Warmwasserbereiters mit Rohrabschnitten, die von der Kreisform abweichend beispielsweise ovale Querschnitte aufweisen, sind denkbar. Wichtig ist, dass der erfindungsgemäße Warmwasserbereiter unabhängig von der Auswahl der Geometrie des Rohrquerschnittes für eine übliche Druckbeaufschlagung geeignet ist.Embodiments of a water heater according to the invention with pipe sections which deviate from the circular shape, for example, have oval cross sections, are conceivable. It is important that the water heater according to the invention is suitable for a conventional pressurization regardless of the selection of the geometry of the pipe cross-section.
Ein weiteres vorteilhaftes Merkmal eines erfindungsgemäßen Warmwasserbereiters sieht vor, dass die Längsachsen der Rohrabschnitte und die Längsachsen der Sammelrohre in einer gemeinsamen Ebene liegen. Dadurch ist eine möglichst flache Bauweise des Warmwasserbereiters für den Wandeinbau gesichert.Another advantageous feature of a water heater according to the invention provides that the longitudinal axes of the pipe sections and the longitudinal axes of the headers lie in a common plane. This ensures the flatest possible construction of the water heater for wall installation.
Zweckmäßig sind bei einem Warmwasserbereiter die Rohrabschnitte jeweils mit den Sammelrohren durch stoffschlüssige Verbindungen, beispielsweise durch Schweißverbindungen, druckfest miteinander verbunden. Ein unbeabsichtigtes Auslaufen des gespeicherten Wassers wird somit zuverlässig vermieden. Bei einem Warmwasserbehälter, der beispielsweise aus Kunststoff hergestellt ist, können die Rohrabschnitte mit den Sammelrohren beispielsweise auch durch Klebeverbindungen stoffschlüssig miteinander verbunden sein.Appropriately, in a water heater, the pipe sections each with the manifolds by cohesive connections, such as welded joints, pressure-tight connected. Accidental leakage of the stored water is thus reliably avoided. In a hot water tank, which is made of plastic, for example, the pipe sections with the headers, for example, by adhesive bonds can be firmly bonded together.
Besonders robust ist die Ausführung eines erfindungsgemäßen Warmwasserbereiters, wenn die Rohrabschnitte zumindest abschnittsweise durch stoffschlüssige Verbindungen, beispielsweise durch Schweiß- oder Klebeverbindungen, miteinander verbunden sind.Particularly robust is the execution of a water heater according to the invention, when the pipe sections are at least partially connected by cohesive connections, for example by welding or adhesive joints.
Die stoffschlüssigen Verbindungen, die zumindest abschnittsweise oder in Abständen zwischen den Rohrabschnitten angeordnet sind, erhöhen die Festigkeit bzw. Steifigkeit des Gehäuses des Warmwasserbereiters. Je nach Ausführung können die Rohrabschnitte des Warmwasserbereiters jeweils direkt aneinander grenzen oder auch voneinander beabstandet sein. Die stoffschlüssigen Verbindungen zwischen den Rohrabschnitten werden dazu im Falle der direkt aneinander grenzenden Rohrabschnitte beispielsweise als Schweißnähte vorgesehen. Im Falle eines Spaltabstandes zwischen den nebeneinander angeordneten Rohrabschnitten kann es beispielsweise erforderlich sein, Verbindungsstege in der Breite des Spaltabstandes vorzusehen bzw. zwischen den Rohrabschnitten zu befestigen, um die geforderte Festigkeit der stoffschlüssigen Verbindung zu erzielen.The cohesive connections, which are arranged at least in sections or at intervals between the pipe sections, increase the strength or rigidity of the housing of the water heater. Depending on the design, the pipe sections of the water heater can each be directly adjacent to each other or spaced apart. The cohesive connections between the pipe sections are provided in the case of directly adjacent pipe sections, for example, as welds. In the case of a gap distance between the juxtaposed pipe sections, it may be necessary, for example, to provide connecting webs in the width of the gap distance or to fix it between the pipe sections in order to achieve the required strength of the integral connection.
Zweckmäßig sind bei einem Warmwasserbereiter gemäß der Erfindung die Rohrabschnitte sowie die Sammelrohre aus einem metallischen Werkstoff, vorzugsweise aus einem korrosionsfesten Stahl in lebensmitteltauglicher Qualität, gefertigt.Suitably, in a water heater according to the invention, the pipe sections and the manifolds made of a metallic material, preferably made of a corrosion-resistant steel in food-grade quality.
Auch andere Werkstoffe, die zur Aufnahme des zu speichernden Wassers geeignet sind, beispielsweise Kunststoffe oder Verbundmaterialien, sind für die Fertigung eines erfindungsgemäßen Warmwasserbereiters einsetzbar.Other materials that are suitable for receiving the water to be stored, such as plastics or composite materials, can be used for the production of a water heater according to the invention.
In einer weiteren Fortbildung eines erfindungsgemäßen Warmwasserbereiters ist an den Außenflächen der Rohrabschnitte und der Sammelrohre eine Isolierung vorgesehen. Durch die Isolierung wird die Energieeffizienz des Warmwasserbereiters deutlich erhöht und es werden Wärmeverluste möglichst reduziert.In a further development of a water heater according to the invention an insulation is provided on the outer surfaces of the pipe sections and the manifolds. The insulation significantly increases the energy efficiency of the water heater and reduces heat losses as much as possible.
Besonders zweckmäßig ist bei einem erfindungsgemäßen Warmwasserbereiter zumindest eine Temperiervorrichtung zum Erwärmen und/oder Abkühlen des gespeicherten Wassers vorgesehen, die beispielsweise durch ein Temperiermedium beheizt und/oder gekühlt wird oder elektrisch beheizt wird.In a water heater according to the invention, it is particularly expedient to provide at least one temperature control device for heating and / or cooling the stored water, which is heated and / or cooled, for example, by a temperature control medium, or electrically heated.
Der Warmwasserbereiter kann mittels einer Temperiervorrichtung auf jegliche denkbare Weise beheizt werden. Eine Beheizung der Temperiervorrichtung beispielsweise durch Fernwärme, Erdwärme oder Solarenergie oder durch ein anderes Temperiermedium ist prinzipiell möglich. Weiters ist eine Beheizung der Temperiervorrichtung durch Kombinationen der einzelnen Temperiermedien möglich. Weiters kann der Warmwasserbereiter beispielsweise durch eine kombinierte Beheizung einer Temperiervorrichtung, die mittels eines Temperiermediums erhitzt wird, und einer weiteren Temperiervorrichtung, die elektrisch beheizt wird, erfolgen. Als elektrische Beheizung können beispielsweise Elektroheizstäbe verwendet werden.The water heater can be heated by means of a tempering in any conceivable way. A heating of the temperature control device, for example by district heating, geothermal or solar energy or by another temperature control is possible in principle. Furthermore, a heating of the temperature control by combinations of the individual tempering is possible. Furthermore, the water heater can, for example, by a combined heating of a temperature control, which is heated by means of a tempering, and a further temperature control, which is electrically heated, take place. As electrical heating, for example Elektroheizstäbe can be used.
In Ergänzung zur Temperiervorrichtung zum Erwärmen oder als Alternative dazu kann bei einem erfindungsgemäßen Warmwasserbereiter auch eine Temperiervorrichtung zum Abkühlen des gespeicherten Wassers vorgesehen sein. Beispielsweise kann ein solcher erfindungsgemäßer Warmwasserbereiter nach dem Prinzip einer Wandkühlung oder zur Versorgung eines Kühlwassersystems auch zur Raumkühlung eingesetzt werden. Auch Kombinationen einer Temperiervorrichtung zum Abkühlen des gespeicherten Wassers, beispielsweise während der Sommermonate, und einer Temperiervorrichtung zum Erwärmen des gespeicherten Wassers in den übrigen Monaten sind mit dem erfindungsgemäßen Warmwasserbereiter denkbar.In addition to the temperature control device for heating or as an alternative thereto, a temperature control device for cooling the stored water can also be provided in a water heater according to the invention. For example, such a water heater according to the invention can also be used for room cooling according to the principle of wall cooling or for supplying a cooling water system. Combinations of a tempering device for cooling the stored water, for example, during the summer months, and a tempering for heating the stored water in the remaining months are conceivable with the water heater according to the invention.
Insbesondere bei der Verwendung des erfindungsgemäßen Warmwasserbereiters mit einer Temperiervorrichtung zum Abkühlen der gespeicherten Flüssigkeit können außer Wasser beispielsweise auch Gemische aus Wasser und einem Kältemittel oder einer vergleichbaren kältebeständigen Flüssigkeit als Speichermedium verwendet werden.In particular, when using the water heater according to the invention with a tempering device for cooling the stored liquid, for example, mixtures of water and a refrigerant or a comparable cold-resistant liquid can be used as a storage medium except water.
Zweckmäßig ist bei einem Warmwasserbereiter gemäß der Erfindung das in Einbaulage untere Grundsammelrohr mit zumindest einem Rohrflansch zum Einbau einer Temperiervorrichtung versehen.Appropriately, in a water heater according to the invention in the installation position lower basic manifold provided with at least one pipe flange for installation of a temperature control.
Der zumindest eine Rohrflansch dient außer zum Einbau der Temperiervorrichtung beispielsweise auch als Revisionsöffnung.The at least one pipe flange is used for the installation of the temperature control, for example, as a revision opening.
In einer Weiterbildung des erfindungsgemäßen Warmwasserbereiters umfasst zumindest eine Temperiervorrichtung eine Rohrwendel, welche von einem Temperiermedium durchströmbar ist und welche vorzugsweise bei einer ungeraden Anzahl an Rohrabschnitten im mittig angeordneten Rohrabschnitt vorgesehen ist.In a further development of the water heater according to the invention, at least one tempering device comprises a coiled tubing, which can be flowed through by a temperature control medium and which is preferably provided with an odd number of pipe sections in the centrally arranged pipe section.
Erfindungsgemäß erfolgt der Einbau der zumindest einen Temperiervorrichtung bei einer ungeraden Anzahl an Rohrabschnitten im mittig angeordneten Rohrabschnitt. Während der Aufheizphase des Warmwasserbereiters entsteht so im mittig angeordneten Rohrabschnitt, in dem sich die Temperiervorrichtung befindet, eine starke Konvektionsströmung des erwärmten Wassers nach oben. Durch diese nach oben gerichtete Strömung wird im mittig angeordneten Rohrabschnitt auch die Wärmeübertragung durch Konvektion verbessert. Weiters bewirkt die im mittleren Rohrabschnitt aufsteigende thermische Strömung, dass in den jeweils symmetrisch angrenzenden Rohrabschnitten ebenfalls eine rasche und gleichmäßige Aufladung bzw. Erwärmung des Brauchwassers erfolgt. Der Warmwasserbereiter wird somit ohne Zeitverzögerung rasch und gleichmäßig von oben nach unten vollständig auf die gewünschte Warmwassertemperatur aufgeheizt. Durch die vollständige Aufheizung des gesamten Fassungsvermögens ist eine thermische Desinfektion des Warmwasserbereiters möglich und die Gefahr einer Legionellenbildung in Toträumen des Behälters somit ausgeschlossen. Aufgrund der raschen und gleichmäßigen Erwärmung ist ein erfindungsgemäßer Warmwasserbereiter im Betrieb besonders wirtschaftlich. Ein solcher Warmwasserbereiter kann bei Bedarf beispielsweise auch tagsüber während einer kurzen Zeitdauer rasch aufgeheizt werden. Ein lange andauernder und somit energieintensiver Aufheizvorgang ist nicht erforderlich.According to the invention, the installation of the at least one tempering device takes place with an odd number of pipe sections in the centrally arranged pipe section. During the heating phase of the water heater so created in the centrally located pipe section in which the tempering is, a strong convection of the heated water upwards. By this upward flow and the heat transfer is improved by convection in the centrally located pipe section. Furthermore, the rising in the central pipe section thermal flow, that also takes place in the respective symmetrically adjacent pipe sections a rapid and uniform charging or heating of the service water. The water heater is thus heated quickly and evenly from top to bottom to the desired hot water temperature without delay. By completely heating the entire capacity of a thermal disinfection of the water heater is possible and the risk of Legionella formation in dead spaces of the container thus excluded. Due to the rapid and uniform heating a hot water heater according to the invention is particularly economical in operation. Such a water heater can, for example, be heated up quickly during the day, for example, during the day for a short period of time. A long-lasting and thus energy-intensive heating process is not required.
Bei einer Ausführung eines Warmwasserbereiters mit einer geraden Anzahl an Rohrabschnitten erfolgt erfindungsgemäß der Einbau der Temperiervorrichtung in einem der mittleren Rohrabschnitte. Weiters ist es denkbar, bei einem Warmwasserbereiter mit mehreren Temperiervorrichtungen diese jeweils voneinander beabstandet beispielsweise in jedem zweiten, dritten oder vierten Rohrabschnitt vorzusehen.In an embodiment of a water heater with an even number of pipe sections according to the invention, the installation of the temperature control takes place in one of the middle pipe sections. Furthermore, it is conceivable for a water heater with a plurality of tempering devices to provide these in each case spaced from each other, for example, in every second, third or fourth pipe section.
Weiters ist es denkbar, alternativ zur Rohrwendel oder als Ergänzung dazu eine elektrisch beheizte Temperiervorrichtung im mittleren Rohrabschnitt vorzusehen. Sowohl eine Rohrwendel, als auch eine elektrisch beheizte Temperiervorrichtung können somit besonders komfortabel sowie wartungsfreundlich durch den Rohrstutzen hindurch in den Speicherraum des Warmwasserbereiters eingeführt werden.Furthermore, it is conceivable to provide an electrically heated temperature control device in the middle pipe section as an alternative to the coiled tubing or as a supplement thereto. Both a coiled tubing, as well as an electrically heated temperature control can thus be introduced particularly comfortable and easy to maintain through the pipe socket into the storage space of the water heater.
In einer Weiterbildung der Erfindung ist bei einem Warmwasserbereiter die Rohrwendel aus einem flexiblen, vorzugsweise wärmedehnbaren Wellrohr gefertigt, wobei ein erster Rohrwendelabschnitt durch ein in Einbaulage ansteigendes, vorzugsweise gewendeltes, Vorlaufrohr sowie ein zweiter Rohrwendelabschnitt durch ein in Einbaulage vertikal fallendes Rücklaufrohr gebildet ist.In a further development of the invention, in a water heater, the coiled tubing is made of a flexible, preferably heat-expandable corrugated pipe, wherein a first coiled tubing portion is formed by a rising in installation position, preferably coiled, flow pipe and a second coiled tubing portion by a vertically falling in installation position return pipe.
Eine Rohrwendel, die aus einem Wellrohr gefertigt ist, bietet den Vorteil, dass die an sich schon große Wärmetauschfläche der Rohrwendel durch die Verwendung eines gerippten Wellrohrs noch weiter vergrößert und somit die Wärmeübertragung der von einem Temperiermedium durchströmten Rohrwendel an das Wasser im Warmwasserbereiter weiter verbessert wird. Weiters bietet ein flexibles, wärmedehnbares Wellrohr den Vorteil, dass durch das Ausdehnen während des Aufheizens eine Verkalkung des Wellrohrs verhindert oder gegenüber einer starren Temperiervorrichtung zumindest deutlich reduziert wird.A coiled tube, which is made of a corrugated tube, has the advantage that the already large heat exchange surface of the coiled tubing is further increased by the use of a corrugated corrugated tube and thus the heat transfer of the coiled tubing through which a temperature control medium to the water in the water heater is further improved , Furthermore, a flexible, heat-expandable corrugated tube offers the advantage that, due to the expansion during heating, calcification of the corrugated tube is prevented or at least significantly reduced compared to a rigid temperature-control device.
Besonders vorteilhaft ist bei einem Warmwasserbereiter gemäß der Erfindung zum Entlüften in die Rohrwendel, vorzugsweise in das Rücklaufrohr der Rohrwendel, ein mit einem Entlüftungsventil verbundenes Kapillarrohr eingeführt.It is particularly advantageous in a water heater according to the invention for venting into the tube coil, preferably in the return pipe of the coiled tubing, introduced a connected to a vent valve capillary tube.
Durch das Kapillarrohr, das zum Entlüften in die Rohrwendel vorzugsweise bis an deren Hochpunkt bzw. oberen Scheitelpunkt eingeführt wird, wird die Rohrwendel während des Befüllens entlüftet. Auch eine regelmäßig wiederkehrende Entlüftung der Rohrwendel während des Betriebs ist möglich. Besonders vorteilhaft befindet sich das mit dem Kapillarrohr verbundene Entlüftungsventil somit außerhalb an der Unterseite des Warmwasserbereiters. Eine Revisionsöffnung im Warmwasserbereiter, um zum Hochpunkt bzw. oberen Scheitelpunkt der in Einbaulage stehend eingebauten Rohrwendel zu gelangen, bzw. ein zusätzliches Entlüftungsrohr, das zur Entlüftung am Hochpunkt der Rohrwendel angeschlossen wird, sind somit nicht erforderlich.Through the capillary tube, which is preferably introduced for venting into the tube spiral to its high point or upper vertex, the coiled tubing is vented during filling. A regularly recurring venting of the coiled tubing during operation is possible. Particularly advantageously, the vent valve connected to the capillary tube is thus located outside on the underside of the water heater. An inspection opening in the water heater, in order to reach the high point or upper vertex of the pipe spiral installed in the installation position, or an additional vent pipe, which is connected for venting at the high point of the coiled tubing, are therefore not required.
Zweckmäßig ist bei einem erfindungsgemäßen Warmwasserbereiter am Grundsammelrohr ein Kaltwassereinlaufrohr anschließbar, wobei das in Einbaulage ins Innere des Grundsammelrohrs ragende freie Ende des Kaltwassereinlaufrohrs mit einem Rohrkrümmer versehen ist, welcher an der Unterseite eines im unteren Grundsammelrohr waagrecht befestigten, vorzugsweise abgewinkelten Prallblechs mündet.Appropriately, in a water heater according to the invention at the base manifold a cold water inlet pipe is connected, wherein the mounting position in the interior of the basic collecting tube projecting free end of the cold water inlet pipe is provided with a pipe bend, which opens at the bottom of a horizontally mounted in the lower base manifold, preferably angled baffle plate.
Besonders vorteilhaft wird das Kaltwasser, das durch ein Kaltwassereinlaufrohr am Grundsammelrohr in das Innere des Behälters gelangt, durch einen Rohrkrümmer am freien Ende des Einlaufrohrs umgelenkt und strömt in seitlicher, waagrechter Richtung aus diesem aus. Ein Prallblech, das im Grundsammelrohr waagrecht befestigt ist, und an dessen Unterseite das mit einem Rohrkrümmer versehene freie Ende des Kaltwassereinlaufrohrs endet, verhindert, dass das kalte Wasser sofort in den direkten oberhalb angeordneten Rohrabschnitt gelangt. Durch das Prallblech wird das einströmende Kaltwasser über die Länge des Grundsammelrohrs im Warmwasserbereiter gleichmäßig verteilt und steigt als über die nebeneinander angeordneten Rohrabschnitte vergleichmäßigte Kaltwasserfront auf. Somit wird auch während des Einleitens von Kaltwasser eine gleichmäßige Temperaturverteilung bzw. Temperaturschichtung innerhalb des Warmwasserbereiters erzielt.Particularly advantageously, the cold water, which passes through a cold water inlet pipe at the base manifold in the interior of the container, deflected by a pipe bend at the free end of the inlet pipe and flows in lateral, horizontal direction from this. A baffle plate, which is horizontally mounted in the base manifold, and at the bottom of which ends the pipe end free end of the cold water inlet pipe, prevents the cold water from immediately entering the pipe section located directly above. Through the baffle plate, the inflowing cold water is evenly distributed over the length of the basic collection pipe in the water heater and rises as over the juxtaposed pipe sections uniformized cold water front. Thus, even during the introduction of cold water, a uniform temperature distribution or temperature stratification within the water heater is achieved.
Vorteilhaft ragt bei einem erfindungsgemäßen Warmwasserbereiter, bei dem ein in Einbaulage vertikales Warmwasserauslaufrohr koaxial in einem Rohrabschnitt, vorzugsweise in einem randseitigen Rohrabschnitt, vorgesehen ist, das oben offene Warmwasserauslaufrohr bis an die Innenseite des Decksammelrohrs.Advantageously protrudes in a hot water heater according to the invention, in which a vertical installation position in the hot water outlet pipe coaxially in a pipe section, preferably in a peripheral pipe section is provided, the open top hot water outlet pipe to the inside of the deck header.
Somit wird direkt an der Innenseite des Decksammelrohrs jeweils nur die oberste, wärmste Wasserschicht aus dem Warmwasserbereiter entnommen und es werden unerwünschte Kurzschlussströmungen während der Wasserentnahme vermieden. Die gleichmäßige Temperaturschichtung in den einzelnen Rohrabschnitten wird durch die Wasserentnahme nicht gestört.Thus, only the uppermost, warmest water layer is removed from the water heater directly on the inside of the deck manifold and it will be avoided unwanted short-circuit currents during water removal. The uniform temperature stratification in the individual pipe sections is not disturbed by the removal of water.
In einer besonders kompakten Ausführung eines erfindungsgemäßen Warmwasserbereiters ist vorgesehen, dass der größte Außendurchmesser und/oder die größte Einbautiefe der mit einer Wärmedämmung versehenen Rohrabschnitte sowie der Sammelrohre höchstens 250 mm beträgt.In a particularly compact embodiment of a water heater according to the invention it is provided that the largest outer diameter and / or the largest installation depth of the provided with a thermal insulation pipe sections and the headers is at most 250 mm.
In dieser Ausführung kann der Warmwasserbereiter beispielsweise in tragenden Zwischenwänden und in Trockenbauwänden in Unterputzausführung oder als Wandvorsatz, der dann verbaut wird, unsichtbar eingebaut werden. Somit kann der Warmwasserbereiter in jedem beliebigen Raum eines Gebäudes vorgesehen werden. Auch ein nachträglicher Einbau eines erfindungsgemäßen Warmwasserbereiters, beispielsweise bei der Renovierung eines Gebäudes, ist aufgrund der besonders kompakten Abmessungen und der unsichtbaren Montage in Unterputzausführung besonders einfach möglich.In this version, the water heater can be installed, for example, in supporting partitions and in drywall walls flush-mounted or as a wall header, which is then installed, invisible. Thus, the water heater can be provided in any room of a building. Also, a subsequent installation of a water heater according to the invention, for example, in the renovation of a building, is particularly easy due to the particularly compact dimensions and invisible mounting flush-mounted.
Je nach Anwendungsfall bzw. abhängig von den baulichen Gegebenheiten ist es möglich, einen erfindungsgemäßen Warmwasserbereiter auch mit einer größeren Einbautiefe vorzusehen. Beispielsweise kann ein Hohlraum in einer Gebäudewand oder einer Vorsatzschale mit einem entsprechend individuell angefertigten Warmwasserbereiter komplett ausgefüllt werden. Oder es wird bei einem Warmwasserbereiter eine besonders dicke Schicht einer Wärmedämmung vorgesehen, um die Energieeffizienz weiter zu erhöhen. Auch diese Ausführungen sind von der Erfindung mitumfasst.Depending on the application or depending on the structural conditions, it is possible to provide a water heater according to the invention with a larger installation depth. For example, a cavity in a building wall or a facing shell can be completely filled with a correspondingly custom-made water heater. Or, in the case of a water heater, a particularly thick layer of thermal insulation is provided in order to further increase energy efficiency. These embodiments are also encompassed by the invention.
In einer Weiterbildung der Erfindung ist bei einem Warmwasserbereitungsmodul zum Einbau in einer Gebäudewand, umfassend einen erfindungsgemäßen Warmwasserbereiter, eine Montagezarge, zumindest eine Anschlussarmatur zum Anschließen einer Temperiermediumsleitung an zumindest eine Temperiervorrichtung sowie Verteilerarmaturen zur wahlweisen Verbindung der Temperiermediumsleitung mit zumindest einem weiteren Verbraucherkreislauf, der allseitig mit einem Wärmedämmungsmaterial umgebene Warmwasserbereiter vertikal stehend innerhalb der Montagezarge befestigt, wobei unterhalb des Warmwasserbereiters in der Montagezarge ein mit einer Serviceöffnung versehener Verteilerkasten zur Aufnahme der zumindest einen Anschlussarmatur sowie der Verteilerarmaturen der einzelnen Verbraucherkreisläufe angeordnet ist.In a further development of the invention, in a water heating module for installation in a building wall, comprising a water heater according to the invention, a mounting frame, at least one connection fitting for connecting a Temperiermediumsleitung to at least one tempering device and manifolds for selectively connecting the Temperiermediumsleitung with at least one other consumer circuit on all sides with a heat insulation material surrounded water heater vertically mounted within the mounting frame, wherein below the water heater in the mounting frame provided with a service opening distribution box for receiving the at least one connection fitting and the manifold fittings of the individual consumer circuits is arranged.
Besonders vorteilhaft ist bei einem Warmwasserbereitungsmodul gemäß der Erfindung zum wahlweisen Zuführen des Temperiermediums entweder zum Temperieren der zumindest einen Temperiervorrichtung des Warmwasserbereiters oder zum Temperieren des zumindest einen weiteren Verbraucherkreislaufs zumindest ein umschaltbares Warmwasserbereiter-Ladeventil vorgesehen.It is particularly advantageous in a hot water preparation module according to the invention for selectively supplying the tempering either for tempering the at least one temperature control of the water heater or for controlling the temperature of the at least one further consumer circuit provided at least one reversible water heater charging valve.
Ein erfindungsgemäßes Warmwasserbereitungsmodul bietet den Vorteil, dass gemeinsam mit dem Warmwasserbereiter sämtliche für den Verbund mit einer zentralen Heizanlage erforderlichen Regelungsventile, Temperaturfühler, Umwälzpumpen etc. und die Sanitäranschlussarmaturen wie z.B. Absperrventile, Sicherheitsgruppe, Druckminderventil und Wasserzähler im in die Montagezarge integrierten Verteilerkasten vorhanden sind.An inventive hot water preparation module has the advantage that, together with the water heater all for the network with a central heating system required control valves, temperature sensors, circulating pumps, etc., and the sanitary connection fittings such as shut-off valves, safety group, pressure reducing valve and water meter are present in the distribution box integrated in the mounting frame.
Somit bietet sich die Verwendung eines erfindungsgemäßen Warmwasserbereitungsmoduls besonders für den flexiblen Einsatz im kommunalen Wohnbau an. Pro Wohnungseinheit wird beispielsweise jeweils ein Warmwasserbereitungsmodul unsichtbar in Unterputzausführung in einer Wand der Wohneinheit eingebaut. Sämtliche Bauteile zur Erzeugung von Warmwasser sowie zur Beheizung und/oder zur Kühlung von Verbraucherkreisläufen sind im Warmwasserbereitungsmodul bereits integriert.Thus, the use of a hot water preparation module according to the invention is particularly suitable for flexible use in municipal housing. For each apartment unit, for example, a hot water preparation module is invisibly installed flush-mounted in a wall of the housing unit. All components for generating hot water as well as for heating and / or for cooling consumer circuits are already integrated in the hot water preparation module.
Wahlweise kann das Temperiermedium, das in Temperiermediumsleitungen von einer zentralen Heizanlage, beispielsweise einer solaren Hausheizungsanlage, einem Hackschnitzel- oder Pelletsofen oder einem Fernwärmekessel, aus beheizt wird, entweder zur Beheizung des in der Montagezarge integrierten Warmwasserbereiters, oder zur Versorgung zumindest eines Verbraucherkreislaufs, beispielsweise einer Fußbodenheizung, dienen. Vorteilhaft ist weiters, dass das Warmwasserbereitungsmodul nur im Bereich des Verteilerkastens mit einer Serviceöffnung, beispielsweise einer Verteilerkastenabdeckung, versehen ist. Somit wird die Montagezarge im eingebauten Zustand als Unterputzausführung überhaupt nicht wahrgenommen.Optionally, the tempering, which is heated in Temperiermediumsleitungen of a central heating system, such as a solar house heating system, a wood chip or pellet stove or a district heating boiler, either for heating the integrated in the mounting frame water heater, or for supplying at least one consumer circuit, for example one Underfloor heating, serve. It is also advantageous that the hot water preparation module is provided only in the region of the distribution box with a service opening, such as a distribution box cover. Thus, the mounting frame is not perceived in the installed state as a flush mounting design.
Sinngemäß kann ein erfindungsgemäßes Warmwasserbereitungsmodul auch zur Kühlung einer Wohnungseinheit beispielsweise während der Sommermonate verwendet werden. Wahlweise ist dazu das Temperiermedium mittels Temperiermediumsleitungen mit einer zentralen Kühlanlage verbunden. Als Temperiermedium wird dazu beispielsweise ein Frostschutzmittel verwendet. Der Warmwasserbereiter wird mittels der mit dem Frostschutzmittel gekühlten Temperiervorrichtung abgekühlt und dient als Kaltwasserbereiter. Das Kaltwasser kann beispielsweise in Kühldeckensegel oder Wandkühlungselemente gefördert werden und dient so zur Kühlung eines Raumes. Auch diese Anwendung des Warmwasserbereitungsmoduls als Kühlvorrichtung ist von der Erfindung mit umfasst.Analogously, a hot water preparation module according to the invention can also be used for cooling a dwelling unit, for example, during the summer months. Optionally, the temperature control medium is connected by means of Temperiermediumsleitungen with a central cooling system. As a tempering for example, an antifreeze is used. The water heater is cooled by means of the cooled with the antifreeze tempering and serves as a chiller. The cold water can be conveyed for example in cooling ceiling sail or wall cooling elements and thus serves to cool a room. This application of the water heating module as a cooling device is also included in the invention.
