Description
Klimabox mit Wärmetauscher und Klimatisierungsverfahren Klimabox with heat exchanger and air conditioning system
Die vorliegende Erfindung betrifft eine Klimabox mit Wärmetauscher zur Temperaturregulierung .Die Erfindung betrifft ferner ein Verfahren zum Betrieb einer solchen Klimabox. The present invention relates to a climate box with a heat exchanger for temperature regulation. The invention further relates to a method for operating such a climate box.
Klimaboxen mit einem Wärmetauscher zur Temperaturregulierung sind aus dem Stand der Technik bekannt. Des Weiteren sind Anlagen zur Temperaturregulierung aus dem Stand der Technik für verschiedene Anwendungen bekannt. Eine Anwen- dungsmöglichkeit für solche Anlagen ist die Klimatisierung von einzelnen Räumen oder von vollständigen Gebäuden. Insbesondere für die Klimatisierung von Rechenzentren werden Anlagen zur Temperaturregulierung benötigt, da durch den Betrieb von Computeranlagen, beispielsweise Serveranlagen, eine erhebliche Wärmeentwicklung erfolgt. Die durch die Serveranlagen produzierte Wärme muss aus dem Raum, in dem die Serveranlagen stehen, notwendigerweise abführt werden, um die maximal zulässigen Betriebstemperaturen für solche Serveranlagen nicht zu überschreiten , welche ohne Abtransport der von den Servern produzierten Wärme innerhalb kurzer Zeit erreicht und überschritten wird. Aus der DE 199 04 667 ist eine Anlage zur Temperaturregulierung eines Gebäudes bekannt. Die dort gezeigte Anlage umfasst ein Klimagerät, welches einen Kühlmittelkreislauf umfasst, wodurch eine indirekte Kühlung mittels des Kühlmittels des Gebäudes oder einzelner Räume ermöglicht wird. Eine solche Kühlung ist insbesondere dahingehend vorteilhaft, dass der zulässige Bereich der relativen Luftfeuchtigkeit und die gewünschte Temperatur sehr gut eingehalten werden können. Die Kühlung der gezeigten Anlage erfolgt in Abhängigkeit der Außentemperatur entweder als indirekte freie Kühlung im Winter, als aktive Kühlung im Sommer sowie als indirekte freie in Kombination mit einer aktiven Kühlung in der Übergangszeit. Die bisherigen Anlagen haben den Nachteil, dass auch bei ausgeschaltetem Wärmetauscher der gesamte Luftstrom über den Wärmetauscher geführt werden muss. Dadurch entstehen luftseitige Druckverluste, die eine höhere Leistungsaufnahme der Ventilatoren und damit höhere Energiekosten verursachen. Es sind deshalb Geräte bekannt, bei denen die Luft bei ausgeschaltetem Wärmetauscher über einen Bypass geführt wird, um den Druckverlust zu umgehen, dieses hat jedoch den Nachteil, dass größere Geräteabmessungen notwendig sind, um einen entsprechenden Bypass realisieren zu können. Gerade bei Rechenzentren werden jedoch Geräte bevorzugt, die einen möglichst geringen Platzbedarf haben, um die Fläche so klein wie möglich halten zu können. Air conditioning boxes with a heat exchanger for temperature control are known from the prior art. Furthermore, prior art temperature control systems are known for various applications. One possible application for such systems is the air conditioning of individual rooms or of complete buildings. In particular, for the air conditioning of data centers systems for temperature regulation are needed, as by the operation of computer equipment, such as server systems, a significant heat generation occurs. The heat produced by the server equipment must necessarily be dissipated from the space in which the server facilities are located, so as not to exceed the maximum allowable operating temperatures for such server equipment, which is reached and exceeded within a short time without dissipating the heat produced by the servers. From DE 199 04 667 a plant for temperature control of a building is known. The plant shown there comprises an air conditioner, which comprises a coolant circuit, whereby an indirect cooling by means of the coolant of the building or individual rooms is made possible. Such cooling is particularly advantageous in that the permissible range of relative humidity and the desired temperature can be maintained very well. The cooling of the system shown is done depending on the outside temperature either as indirect free cooling in winter, as active cooling in summer and as indirect free in combination with active cooling in the transitional period. The previous systems have the disadvantage that even with the heat exchanger switched off, the entire air flow must be routed through the heat exchanger. This results in air-side pressure losses, which cause a higher power consumption of the fans and thus higher energy costs. It is therefore devices known, in which the air is bypassed with the heat exchanger switched off in order to avoid the pressure loss, but this has the disadvantage that larger device dimensions are necessary in order to realize a corresponding bypass can. Especially with data centers, however, devices are preferred that have the smallest possible space required to keep the area as small as possible.
Aufgabe der vorliegenden Erfindung ist es daher eine Kiimabox mit Wärmetauscher bereitzustellen, welche auch bei ausgeschaltem Wärmetauscher keine höheren Energiekosten verursacht und luftseitige Druckverluste weitestgehend vermeidet. Es ist eine weitere Aufgabe der Erfindung, eine Anlage zur Temperaturregulierung sowie ein Verfahren zum Betrieb einer Anlage zur Temperaturregulierung bereitzustellen. Object of the present invention is therefore to provide a Kiimabox with heat exchanger, which causes no higher energy costs and heat-side pressure losses largely avoided even when the heat exchanger. It is a further object of the invention to provide a temperature control system and method for operating a temperature control system.
Die Aufgabe wird erfindungsgemäß gelöst durch eine Klimabox zur Temperaturrege- lung durch die mindestens ein Luftstrom leitbar ist und die mindestens einen Wärmetauscher enthält, dadurch gekennzeichnet, dass der Wärmetauscher beweglich in der Klimabox angeordnet ist und um einen Drehpunkt zwischen mindestens einer Betriebsposition und einer Ruheposition bewegbar ist. Weitere Ausführungsformen sind Gegenstand der Unteransprüche oder nachfolgend beschrieben. The object is achieved by a Klimabox for temperature control by the at least one air flow is conductive and containing at least one heat exchanger, characterized in that the heat exchanger is movably disposed in the Klimabox and about a pivot between at least one operating position and a rest position movable is. Further embodiments are the subject matter of the subclaims or described below.
Die erfindungsgemäße Klimabox weist bevorzugt einen Wärmetauscher auf, der zwischen genau einer Betriebsposition und einer Ruheposition bewegbar ist. Als Betriebsposition wird dabei im Sinne der Erfindung eine Position der Klimabox verstanden, bei der die in die Klimabox eintretende Luft durch den Wärmetauscher geführt wird und der Wärmetauscher in Betrieb ist. Entsprechend wird unter Ruheposition eine Position des Wärmetauschers in der Klimabox verstanden, bei der der Wärmetauscher außerhalb des Luftstroms im Klimagerät angeordnet ist und nicht in Betrieb ist. Durch die Befestigung des Wärmetauschers an einem Drehpunkt in der Klimabox lässt sich der Wärmetauscher zwischen der Betriebsposition und der Ruheposition umklappen, es liegt somit eine klappbare bzw. drehbare Befestigung des Wärmetauschers in der Klimabox vor. Die Bewegung zwischen den verschiedenen Positionen erfolgt beispielsweise elektrisch oder hydraulisch, wobei auch mechanische Klappmechanismen oder andere Bewegungsmechanismen einsetzbar sind. Bei der erfindungsgemäßen Klimabox ist der Wärmetauscher bevorzugt zwischen genau einer Betriebsposition und genau einer Ruheposition bewegbar. In der Ruheposition ist der Wärmetauscher dabei bevorzugt senkrecht zum Boden der Klimabox und parallel zur längeren Seitenwand der Klimabox angeordnet weniger bevorzugt sind Ruhepositionen in denen der Wärmetauscher schräg in der Klimabox angeordnet ist, d.h. mit einem Winkel zum Boden, der nicht rechtwinklig ist. Dabei entspricht die maximale Höhs des Wärmetauschers in der Ruheposition bevorzugt der Höhe der Klimabox. Hierdurch ist gewährleistet, dass eine besonders gute Ausnutzung der vorhandenen Fläche für die Temperierung, insbesondere die Kühlung gegeben ist. Es sind jedoch auch Ausführungsformen denkbar, bei denen der Wärmetauscher geringere Abmessungen aufweist. The climate box according to the invention preferably has a heat exchanger which is movable between exactly one operating position and a rest position. In the context of the invention, the operating position is understood to be a position of the climatic box in which the air entering the climate box is passed through the heat exchanger and the heat exchanger is in operation. Accordingly, under rest position, a position of the heat exchanger in the Klimabox understood, in which the heat exchanger is located outside the air flow in the air conditioner and is not in operation. By attaching the heat exchanger at a pivot point in the Klimabox the heat exchanger can be folded between the operating position and the rest position, there is thus a hinged or rotatable attachment of the heat exchanger in the Klimabox. The movement between the various positions, for example, electrically or hydraulically, whereby mechanical folding mechanisms or other movement mechanisms can be used. In the climate box according to the invention, the heat exchanger is preferably movable between exactly one operating position and exactly one rest position. In the rest position of the heat exchanger is preferably perpendicular to the bottom of the Klimabox and parallel to the longer side wall of the Klimabox arranged less preferred are rest positions in which the heat exchanger is arranged obliquely in the Klimabox, ie at an angle to the ground, which is not rectangular. In this case, the maximum height of the heat exchanger in the rest position preferably corresponds to the height of the climate box. This ensures that a particularly good utilization of the existing surface for the temperature, in particular the cooling is given. However, embodiments are also conceivable in which the heat exchanger has smaller dimensions.
Der Wärmetauscher ist in der erfindungsgemäßen Klimabox im Betriebszustand be- vorzugt entlang der Diagonalen der Klimabox zwischen zwei sich gegenüberliegenden Ecken angeordnet. The heat exchanger is preferably arranged in the climate box according to the invention in the operating state along the diagonal of the climate box between two opposite corners.
Der Wärmetauscher ist beispielsweise als Verdampfer oder als Kühler ausgestaltet. Die Steuerung und Regelung der Klimabox erfolgt beispielsweise durch entspre- chende Software. The heat exchanger is designed, for example, as an evaporator or as a cooler. The control and regulation of the Klimabox, for example, by appropriate software.
Die erfindungsgemäße Klimbox hat gegenüber herkömmlichen Klimaboxen den Vorteil, dass die luftseitigen Druckverluste gegenüber herkömmlichen Klimaboxen reduziert werden können. Der Wärmetauscher ist, wenn er nicht in Betrieb ist, aus dem Luftstrom geklappt, so dass hierdurch Druckverluste, die sonst durch Durchströmen des ausgeschalteten Wärmetauschers entstehen, reduziert werden können. Hierdurch können die Energiekosten für den Betrieb deutlich gesenkt werden. Gleichzeitig ist eine Beibehaltung der vorteilhaften geringen Abmessungen möglich, da es nicht notwendig ist, die Luft bei ausgeschaltetem Wärmetauscher über einen Bypass zu führen, um Druckverluste zu vermeiden. Die Klimabox kann in verschiedenen Betriebszuständen betrieben werden, beispielsweise bei Temperaturen der zuströmenden Luft, auch Außenluft genannt, die oberhalb von einer Temperatur Ti liegen. Ab einer höheren Temperatur T2 könnte eine aktive Kühlung mittels des Wärmetauschers in Betriebsposition erfolgen, wäh- rend es im Bereich oberhalb von Ti und unterhalb von T2 lediglich ein Mischbetrieb aus aktiver und direkter Kühlung erfolgen könnten, wodurch wiederum die Energiekosten gesenkt werden könnten. Unterhalb von Ti ist eine direkte freie Kühlung möglich d.h. der Wärmetauscher ist ausgeschaltet und in Ruheposition befindlich, so dass der Energiebedarf deutlich gesenkt werden kann. Durch die Nutzung der freien Kühlung kann eine hohe Energieeffizienz gewährleistet werden, da keine Energieverluste, beispielsweise durch zusätzliche Wärmetauscher, auftreten. The climate box according to the invention has the advantage over conventional air conditioning boxes that the air-side pressure losses compared to conventional air conditioning boxes can be reduced. The heat exchanger is, when it is not in operation, folded out of the air flow, so that this pressure losses, which otherwise arise by flowing through the switched-off heat exchanger, can be reduced. As a result, the energy costs for operation can be significantly reduced. At the same time a maintenance of the advantageous small dimensions is possible, since it is not necessary to lead the air with the heat exchanger switched off via a bypass in order to avoid pressure losses. The Klimabox can be operated in different operating conditions, for example, at temperatures of the incoming air, also called outside air, which are above a temperature Ti. From a higher temperature T 2 , active cooling could take place by means of the heat exchanger in the operating position, while in the region above Ti and below T 2, only a mixed operation of active and direct cooling could take place, which in turn could reduce energy costs. Below Ti, direct free cooling is possible, ie the heat exchanger is switched off and in the rest position, so that the energy requirement can be significantly reduced. By using the free cooling high energy efficiency can be ensured because no energy losses, for example, by additional heat exchanger occur.
In einer weiter vorteilhaften Ausgestaltung könnte mindestens eine In a further advantageous embodiment, at least one could
Ventilatoreinrichtung vorgesehen sein. Diese Ventilatoreinrichtung könnte außerhalb des zu kühlenden Raums angeordnet sein, beispielsweise im Freien, um den Abtransport der warmen Luft zu verbessern. Insbesondere bei Außentemperaturen oberhalb von 17°C könnte ein solcher zusätzlicher Abtransport von Wärme durch die Ventilatoreinrichtung erfolgen. Die erfindungsgemäßen Klimaboxen werden beispielsweise in Anlagen zur Temperaturregulierung von Rechenzentren bzw. Serveranlagen eingesetzt. Dabei werden die 3 verschiedenen oben bereits erläuterten Bethebszustände durchlaufen. Bei sehr hohen Temperaturen wird die gesamte Anlage in der Betriebsweise aktive Kühlung betrieben. In diesem Fall ist der Wärmetauscher in der Betriebsposition angeordnet, wobei sämtliche Luft durch den Wärmetauscher strömt und dort gekühlt wird. Bei etwas niedrigeren Temperaturen erfolgt ein Mischbetrieb aus aktiver Kühlung und direkter Kühlung, d.h. nur ein Teil des gesamt Luftstromes wird über den Wärmetauscher geführt, ein anderer Teil des Luftstromes wird außerhalb der Klimabox dem gekühlten Luftstrom zugemischt. Bei diesem Luftstrom muss sich beispielsweise um Außenluft handeln oder um Umluft aus der Gesamtanlage. In der dritten Betriebsweise der direkten freien Kühlung wird die Anlage ausschließlich mit Außenluft gekühlt. In diesem Betriebszustand befindet sich der Wärmetauscher in Ruheposition und die Klimabox kann ungehindert vom Luftstrom durchströmt werden. Es gibt in diesem Fall also zwei Betriebszustände, bei denen der Wärmetauscher im Betriebszustand durchströmt wird und einen Zustand, in dem der Wärmetauscher aus dem Luftstrom geklappt ist und nicht durchströmt wird. Hierdurch können, wie oben erläutert, die luftseitigen Druckverluste deutlich reduziert werden. Fan device may be provided. This fan device could be arranged outside the space to be cooled, for example outdoors to improve the removal of the warm air. Especially at outside temperatures above 17 ° C, such additional removal of heat could be done by the fan device. The climate boxes according to the invention are used for example in plants for temperature regulation of data centers or server systems. In the process, the three different states of operation already explained above are run through. At very high temperatures, the entire system is operated in the active cooling mode. In this case, the heat exchanger is arranged in the operating position, wherein all air flows through the heat exchanger and is cooled there. At somewhat lower temperatures, a mixed operation of active cooling and direct cooling, ie only a portion of the total air flow is passed through the heat exchanger, another part of the air flow is mixed outside the Klimabox the cooled air stream. For example, this airflow must be outside air or circulating air from the entire system. In the third mode of direct free cooling, the system is cooled exclusively with outside air. In this operating state, the heat exchanger is in rest position and the air box can be flowed through unhindered by the air flow. There are in this case therefore two operating states in which the heat exchanger is flowed through in the operating state and a state in which the heat exchanger is folded out of the air flow and is not flowed through. As a result, as explained above, the air-side pressure losses can be significantly reduced.
Die erfindungsgemäßs Mischbox lässt sich beispielsweise ais Teii eines Kiimagerä- tes oder als Klimagerät verwenden. Die Klimabox wird dabei zur Kühlung von Re- chenzentren, Servern, Rechnern oder Serveranlagen sowie Server-Racks verwendet. Es ist auch möglich die erfindungsgemäße Klimabox mit einer Mischbox zu kombinieren, die eine weitere Optimierung der Betriebszustände erlaubt. Eine solche Mischbox weißt beispielsweise verschiedene Klappen, nämlich eine Außenluftklappe, eine Umluftklappe und eine Mischluftklappe auf, die eine gezielte Mischung ver- schieden temperierter Luftströme erlaubt. Eine solche Mischbox ist beschrieben in der Europäischen Patentanmeldung 09 005 824.9, auf die hiermit Bezug genommen wird. Die Kombination einer Klimabox mit dieser Mischbox für eine direkte freie Kühlung ist somit ebenfalls Teil der Anmeldung. Nachstehend wird die Erfindung an Hand eines Ausführungsbeispiels beschrieben, das schematisch in der Zeichnung dargestellt ist. Dabei ist: The mixing box according to the invention can be used, for example, as a part of a kiln deposit or as an air conditioning unit. The Klimabox is used for the cooling of computer centers, servers, computers or server systems as well as server racks. It is also possible to combine the inventive Klimabox with a mixing box, which allows a further optimization of the operating conditions. Such a mixing box, for example, has various flaps, namely an outside air flap, a recirculating air flap and a mixed air flap, which permits a targeted mixture of different tempered air streams. Such a mixing box is described in European Patent Application 09 005 824.9, to which reference is hereby made. The combination of a Klimabox with this mixing box for a direct free cooling is thus also part of the application. The invention will be described with reference to an embodiment which is shown schematically in the drawing. Where:

Fig.1a zeigt eine Ausführungsform der erfindungsgemäßen Klimabox 1 , mit einem Wärmetauscher 9 in Betriebsposition. Die von der Oberseite der Klimabox einströ- mende Luft, die in Fig. 1b durch Pfeile gekennzeichnet ist, wird entsprechend vollständig durch den Wärmetauscher 9 zum Boden 8 der Klimabox transportiert. Der Wärmetauscher 9 ist an seinem unteren Ende mit einem Gelenk 2 verbunden, das als Drehpunkt dient. Der Drehpunkt kann in anderen nicht gezeigten Ausführungen auch an anderer Stelle entlang des Wärmetauschers angeordnet sein. An seinem oberen Ende ist der Wärmetauscher 9 durch einen oberen Rahmen 2, gegen den er lehnt, begrenzt. Parallel zum Wärmetauscher 9 verläuft eine seitliche Abdichtung 5, die an der nicht dargestellten vorderen Seitenwand befestigt ist. Durch die seitliche Abdichtung 5, den oberen Rahmen 2 und eine Dichtrinne 6 am Boden ist sicherge- stellt, dass der Luftstrom nicht seitlich oder ober- oder unterhalb am Wärmetauscher vorbeigeführt werden kann. Der Boden 8 ist offen gestaltet, so dass die Luft ungehindert durchströmen kann. Im oberen Bereich der Klimabox 1 ist ein Elektrokasten 7 angeordnet, der zur Steuerung und Regelung der Klimabox dient. Fig. 1c zeigt die perspektivische Ansicht. Dabei ist zu erkennen, dass sich der Wärmetauscher 9 über die gesamte Breite der Klimabox erstreckt und etwa diagonal die zwei sich gegenüberliegenden Ecken miteinander verbindet. Im unteren Bereich liegt der Wärmetauscher 9 an der Dichtrinne 6 an. In Fig. 2a ist die Klimabox mit Wärmetauscher 9 im Ruhezustand gezeigt. Der Wärmetauscher 9 ist dabei parallel zur Seitenwand 4 angeordnet und steht auf der Schiene 3, die sich im Boden der Klimabox befindet. Entsprechend strömt die Luft, wie in Fig. 2b zu sehen, von der Oberseite der Klimabox zum Boden 8 der Klimabox ohne durch den Wärmetauscher zu strömen. Der Wärmetauscher 9 erstreckt sich dabei fast vom Boden 8 bis zur Oberseite der Klimabox 1. 1a shows an embodiment of the invention Klimabox 1, with a heat exchanger 9 in the operating position. The air flowing in from the top of the climate box corresponding air, which is indicated by arrows in Fig. 1b, is correspondingly transported completely through the heat exchanger 9 to the bottom 8 of the air box. The heat exchanger 9 is connected at its lower end with a hinge 2, which serves as a fulcrum. The pivot point can be arranged in other embodiments, not shown, elsewhere along the heat exchanger. At its upper end, the heat exchanger 9 is limited by an upper frame 2, against which it leans. Parallel to the heat exchanger 9 extends a lateral seal 5 which is fixed to the front side wall, not shown. The lateral seal 5, the upper frame 2 and a sealing channel 6 on the bottom ensure that the air flow can not be led past the heat exchanger laterally or above or below it. The bottom 8 is designed open, so that the air can flow through unhindered. In the upper part of the Klimabox 1, an electric box 7 is arranged, which serves for controlling and regulating the Klimabox. Fig. 1c shows the perspective view. It can be seen that the heat exchanger 9 extends over the entire width of the Klimabox and approximately diagonally connects the two opposite corners. In the lower part of the heat exchanger 9 is located on the sealing groove 6. In Fig. 2a the Klimabox is shown with heat exchanger 9 at rest. The heat exchanger 9 is arranged parallel to the side wall 4 and stands on the rail 3, which is located in the bottom of the Klimabox. Accordingly, as seen in Figure 2b, the air flows from the top of the air box to the bottom 8 of the air box without passing through the heat exchanger. The heat exchanger 9 extends almost from the bottom 8 to the top of the Klimabox. 1
