Description
Vorrichtung zur Klimatisierung von Technikräumen, insbesondere MeßräumenDevice for air conditioning technical rooms, especially measuring rooms
Beschreibungdescription
Die Erfindung betrifft eine Vorrichtung zur Klimatisierung von Technikräumen, insbesondere Meßräumen umfassend einen Meßraumboden, Meßraumwände und eine Meßraumdecke mittels wenigstens einer, vorzugsweise über der Meßraumdecke angeordneten Klimaeinrichtung, durch welche dem Meßraum über vorzugsweise im Meßraumdeckenbereich angeordnete Zuluftöffnungen klimatisierte Luft zuführbar ist, welche nach Zirkulation in dem Meßraum aus diesem über Abluftöffnungen wieder abführbar und wenigstens teilweise erneut der Klimaeinrichtung zuführbar ist.The invention relates to a device for the air conditioning of technical rooms, in particular measuring rooms comprising a measuring room floor, measuring room walls and a measuring room ceiling by means of at least one air conditioning device, preferably arranged above the measuring room ceiling, by means of which conditioned air can be supplied to the measuring room via supply air openings, preferably arranged in the measuring room ceiling area, which after circulation in the measuring space can be removed from it again via exhaust air openings and at least partially fed back to the air conditioning device.
Ein Meßraum ist ein Raum oder Teilbereich eines Raumes, in dem festgelegte Anforderungen an die Umgebungsbedingungen, z.B. hinsichtlich zulässiger Temperaturen, Schwingungen, Feuchte und dergleichen
erfüllt sein müssen, damit Werte von Meßgrößen mit vorgegebenen Meßunsicherheiten ermittelt werden können. Derartige Meßräume dienen zum einen präziser, reproduzierbarer Messungen, zum anderen aber auch der Bearbeitung beispielsweise von feinmechanischen Werkstücken und dergleichen.A measuring room is a room or part of a room in which specified requirements for the ambient conditions, for example with regard to permissible temperatures, vibrations, humidity and the like must be fulfilled so that values of measured variables with specified measurement uncertainties can be determined. Such measuring rooms are used on the one hand for precise, reproducible measurements, but on the other hand also for processing, for example, precision mechanical workpieces and the like.
Die Klassifizierung und die Kenngrößen derartiger Meßräume sind in den VDI/VDE-Richtlinien 2627 Blatt 1 dargelegt, auf die insoweit Bezug genommen wird.The classification and the parameters of such measuring rooms are set out in VDI / VDE guidelines 2627 sheet 1, to which reference is made in this respect.
Um in derartigen Meßräumen eine Temperaturschichtung zu vermeiden, sind bei bekannten Meßräumen Luftführungsein- richtungen vorgesehen, welche eine Luftzirkulation und Durchflutung des Raumes im Gegenstromprinzip ermöglichen. Eine aus dem Stand der Technik bekannte Vorrichtung zur Klimatisierung von Meßräumen ist in Fig.5 schematisch dargestellt. Wie in Fig. 5 dargestellt ist, umfaßt ein Meßraum 10 einen Meßraumboden 11, Meßraumwände 12 und eine Meßraumdecke 13. In der Meßraumdecke 13 sind Zuluftöffnungen 20 vorgesehen, durch welche klimatisierte Luft, die von einer in Fig. 5 nicht dargestellten Klimaeinrichtung abgegeben wird, dem Meßraum 10 zuführbar ist. Die Zuluftöffnungen 20 sind dabei im wesentlichen über die Meßraumdecke 13 gleichverteilt. Sie verleihen der in den Meßraum strömenden klimatisierten Luft einen Drall, so daß die Luft aus den Zuluftöffnungen 20 spiralförmig zum Meßraumboden 11 strömt. Bei einer derartigen Vorrichtung strömen sehr große Luftmengen pro Zeiteinheit - bis zu dem Sechigfachen des Meßraumvolumens pro Stunde - in das Innere des Meßraums 10. Die in dem Meßraum umgewälzte klimatisierte Luft wird über (in Fig. 5 nicht dargestellte) Abluftöffnungen wenigstens teilweise der
Klimaeinrichtung wieder zugeführt und erneut klimatisiert. Darüber hinaus kann auch wenigstens ein Teil als Fortluft in die Atmosphäre entströmen. Problematisch bei einer derartigen bekannten Vorrichtung zur Klimatisierung von Meßräumen ist es, daß sehr große Luftmengen durch den Meßraum 10 geführt werden, die zur Aufbereitung große und aufwendige Klimaeinrichtungen erfordern und wahrnehmbare Luftströmungen erzeugen.In order to avoid temperature stratification in such measuring rooms, air guiding devices are provided in known measuring rooms which allow air circulation and flooding of the room in the counterflow principle. A device known from the prior art for air conditioning measuring rooms is shown schematically in FIG. As shown in FIG. 5, a measuring room 10 comprises a measuring room floor 11, measuring room walls 12 and a measuring room ceiling 13. In the measuring room ceiling 13 supply air openings 20 are provided through which conditioned air, which is emitted by an air conditioning device not shown in FIG. 5, can be fed to the measuring space 10. The supply air openings 20 are essentially evenly distributed over the measuring room ceiling 13. They impart a swirl to the conditioned air flowing into the measuring space, so that the air flows from the supply air openings 20 in a spiral to the measuring space floor 11. In such a device, very large amounts of air per unit of time - up to six times the volume of the measuring room per hour - flow into the interior of the measuring room 10. The conditioned air circulated in the measuring room is at least partially the exhaust air openings (not shown in FIG. 5) Air conditioning supplied again and air conditioned again. In addition, at least some of it can escape into the atmosphere as exhaust air. The problem with such a known device for air conditioning measuring rooms is that very large amounts of air are passed through the measuring room 10, which require large and complex air conditioning devices for preparation and produce perceptible air flows.
Aufgabe der Erfindung ist es daher, eine Vorrichtung zur Klimatisierung von Meßräumen der gattungsgemäßen Art derart weiterzubilden, daß eine Umwälzung klimatisierter Luft in dem Meßraum unter Beibehaltung einer präzise einzustellenden Meßraumtemperatur mit möglichst einfachen technischen Mitteln, insbesondere mit möglichst kleinen Klimaeinrichtungen möglich ist.The object of the invention is therefore to develop a device for air conditioning measuring rooms of the generic type in such a way that circulating conditioned air in the measuring room while maintaining a precisely adjustable measuring room temperature is possible with the simplest possible technical means, in particular with the smallest possible air conditioning devices.
Diese Aufgabe wird bei einer Vorrichtung zur Klimatisierung von Meßräumen der eingangs beschriebenen Art dadurch gelöst, daß unterhalb der Meßraumdecke eine Luftleiteinrichtung angeordnet ist, durch welche die von der Klimaeinrichtung abgegebene klimatisierte Luft in Richtung der Meßraumwände geleitet wird und welche auf die Meßraumwände gerichtete Zuluftöffnungen aufweist.This object is achieved in a device for air conditioning measuring rooms of the type described in the introduction in that an air guiding device is arranged below the ceiling of the measuring room, through which the conditioned air released by the air conditioning device is directed in the direction of the measuring room walls and which has supply air openings directed towards the measuring room walls.
Die Anordnung von Luftleiteinrichtungen, durch welche die von der Klimaeinrichtung abgegebene klimatisierte in Richtung der Meßraumwände geleitet wird und welche auf die Meßraumwände gerichtete Zuluftöffnungen aufweist, hat den besonders großen Vorteil, daß die von der Klimaeinrichtung abgegebene Luft in laminarer Strömung von der Meßraumdecke im wesentlichen entlang der Meßraumwände zum Meßraumboden strömt und dort nicht nur in dem Meßraum umgewälzt wird und dabei die Wärme der in
dem Meßraum befindlichen Luft aufnimmt, sondern zusätzlich auch noch die Wärme der Meßraumwände aufnimmt und abführt. Die Durchflutung des Raumes erfolgt dabei im Gleichstromprinzip.The arrangement of air guiding devices, through which the air-conditioned device released by the air conditioning device is directed in the direction of the measuring room walls and which has supply air openings directed towards the measuring room walls, has the particularly great advantage that the air released by the air conditioning device in a laminar flow essentially along the ceiling of the measuring room the walls of the measuring room flows to the floor of the measuring room and is not only circulated there in the measuring room and the heat of the absorbs air located in the measuring room, but additionally also absorbs and dissipates the heat of the measuring room walls. The room is flooded using the direct current principle.
Aufgrund umfänglicher Versuche hat sich dabei gezeigt, daß bei einer derartigen Führung der Luft in dem Meßraum wesentlich kleinere Umwälzmengen notwendig sind, die nur etwa dem Sechsfachen des Meßraumvolumens pro Stunde entsprechen. Durch diese kleinere Umwälzmenge entstehen weniger Störungen in der Luftströmung, beispielsweise durch Turbulenzen oder dgl..Extensive tests have shown that with such a guidance of the air in the measuring room, much smaller circulating quantities are necessary, which correspond only to about six times the measuring room volume per hour. This smaller amount of circulation causes fewer disturbances in the air flow, for example due to turbulence or the like.
Was die Anordnung der Abluftöffnungen betrifft, so ist vorzugsweise vorgesehen, daß die wenigstens eine Abluftöffnung so benachbart zu oder als Teil der Luftleiteinrichtung angeordnet ist, daß sie von den Zuluftöffnungen möglichst weit entfernt und den Meßraumwänden dicht benachbart angeordnet ist. Diese Anordnung der Abluftöffnung ermöglicht eine besonders optimale Zirkulation der von der Klimaeinrichtung abgegebenen klimatisierten Luft in dem Meßraum in laminarer Strömung.As far as the arrangement of the exhaust air openings is concerned, it is preferably provided that the at least one exhaust air opening is arranged so as to be adjacent to or as part of the air guiding device in such a way that it is as far away as possible from the supply air openings and is arranged closely adjacent to the measuring room walls. This arrangement of the exhaust air opening enables a particularly optimal circulation of the air-conditioned air emitted by the air conditioning device in the measuring space in laminar flow.
Die Ausbildung der Luftleiteinrichtung kann rein prinzipiell auf die unterschiedlichste Art und Weise realisiert sein. Eine insbesondere hinsichtlich ihrer Herstellung und Anordnung in dem Meßraum besonders vorteilhafte Ausführungsform sieht vor, daß die Luftleiteinrichtung wenigstens eine mit Abstand unterhalb der Meßraumdecke angeordnete vorzugsweise ebene Luftleitblende umfaßt, welche auf ihrer der Klimaeinrichtung zugewandten Seite zur Klimaeinrichtung hin abgewinkelt ist und auf ihrer der Klimaeinrichtung
abgewandten und wenigstens einer Meßraumwand zugewandten Seite unter Ausbildung der wenigstens einen Zuluftöffnung endet. Durch eine derartige abgewinkelte Luftleitblende wird auf besonders einfache Weise eine laminare Strömung der von der Klimaeinrichtung abgegebenen klimatisierten Luft hin zu den Meßraumwänden ermöglicht.In principle, the design of the air guiding device can be implemented in a wide variety of ways. An embodiment which is particularly advantageous with regard to their manufacture and arrangement in the measuring room provides that the air guiding device comprises at least one, preferably flat, air guiding plate arranged at a distance below the measuring room ceiling, which is angled toward the air conditioning device on its side facing the air conditioning device and on its side towards the air conditioning device facing away and facing at least one wall of the measuring room ends forming the at least one supply air opening. Such an angled air baffle enables a laminar flow of the air-conditioned air emitted by the air-conditioning device to the walls of the measuring room in a particularly simple manner.
Eine andere sehr vorteilhafte Ausführungsform sieht vor, daß zwischen dem ebenen Luftleitblech und der Meßraumdecke ein weiteres Luftleitblech angeordnet ist, welches so gebogen ist, daß zusammen mit dem ebenen Luftleitblech ein Luftführungskanal entsteht, der auf seiner der Klimaeinrichtung zugewandten Seite eine Querschnittsverringerung aufweist. Durch diesen Luftführungskanal und insbesondere durch die in ihm angeordnete Verengung wird eine besonders optimale Strömung der die Klimaeinrichtung verlassenden klimatisierten Luft ermöglicht.Another very advantageous embodiment provides that a further air baffle is arranged between the flat air baffle and the measuring room ceiling, which is bent so that together with the flat air baffle an air duct is formed which has a cross-sectional reduction on its side facing the air conditioning device. A particularly optimal flow of the conditioned air leaving the air conditioning device is made possible by this air duct and in particular by the constriction arranged in it.
Um hierbei eine weitere Optimierung der Strömung in dem Luftführungskanal zu realisieren, ist dabei vorzugsweise vorgesehen, daß das ebene Luftleitblech an seiner dem Luftführungskanal zugewandten Seite eine Mehrzahl von Öffnungen aufweist. Durch diese Nachströmöffnungen wird auf vorteilhafte Weise eine Induktion der Luft von der Rauminnenseite in den von der Klimaeinrichtung abgegebenen temperierten Volumenstrom erreicht. Es tritt hierdurch eine Durchmischung und dadurch ein Temperaturausgleich der durch die Öffnungen einströmenden Luft und der von der Klimaeinrichtung abgegebenen Luft auf. Auf diese Weise wird die dem Meßraum zuzuführende Luft bereits in der Luftleiteinrichtung temperiert.In order to further optimize the flow in the air duct, it is preferably provided that the flat air baffle has a plurality of openings on its side facing the air duct. These post-flow openings advantageously achieve induction of the air from the inside of the room into the temperature-controlled volume flow output by the air conditioning device. As a result, mixing occurs and thus temperature compensation of the air flowing in through the openings and the air emitted by the air conditioning device. In this way, the air to be supplied to the measuring space is already tempered in the air guiding device.
Was die Gestalt der Luftleitblende betrifft, so wurden
bislang noch keine näheren Angaben gemacht. Vorteilhafterweise ist vorgesehen, daß die Luftleitblende unterhalb der Meßraumdecke derart ausgedehnt ist, daß ihre Überdeckungsflache größer oder gleich der Fläche ist, die von einer in dem Meßraum angeordneten Einrichtung, beispielsweise einer Meßeinrichtung oder einer Bearbeitungsmaschine, überdeckt wird. Auf diese Weise ergibt sich ein optimaler Luftstrom in dem Meßraum.As for the shape of the air baffle, so were so far no further details have been given. It is advantageously provided that the air baffle is extended below the ceiling of the measuring room in such a way that its covering area is greater than or equal to the area covered by a device arranged in the measuring room, for example a measuring device or a processing machine. This results in an optimal air flow in the measuring room.

Ein in Fig. 4 schematisch dargestellter Meßraum 10 umfaßt einen Meßraumboden 11, Meßraumwände 12 und eine Meßraumdecke 13.A measuring room 10 shown schematically in FIG. 4 comprises a measuring room floor 11, measuring room walls 12 and a measuring room ceiling 13.
Oberhalb der Meßraumdecke 13 ist auf an sich bekannte Weise eine Klimaeinrichtung 30 befestigt, durch welche dem Meßraum 10 klimatisierte Luft zuführbar ist, welche in dem Meßraum 10 umgewälzt wird und so einen Temperaturausgleich bewirkt. Wie aus Fig. 4 hervorgeht, ist unterhalb der Klimaeinrichtung 30 eine Luftleiteinrichtung in Form einer Luftleitblende 50 vorgesehen, welche benachbart zu einer im wesentlichen zentral in der Klimaeinrichtung 30 angeordneten Abluftöffnung 60 abgewinkelt ist und auf ihrer der Abluftöffnung 60 abgewandten Seite unter Ausbildung von Zuluftöffnungen 52, die zwischen der Luftleitblende 50 und der Meßraum- deke 13 ausgebildet und den Meßraumwänden 12 zugewandt sind, endet. Durch diese Luftleitblende 50 wird die von der Klimaeinrichtung 30 abgegebene klimatisierte Luft in laminarer Strömung hin zu den Meßraumwänden 12 gelenkt, an welchen sie nach unten strömt und im Bereich des Meßraumbodens 11 umgelenkt wird, um dann wieder durch die Abluftöffnung 60 in die Klimaeinrichtung 30 zu strömen, in der sie erneut aufbereitet, beispielsweise abgekühlt, entstaubt und gereinigt wird, bevor sie
wieder über die Luftleitblende 50 dem Meßraum 10 zugeführt wird. Die in laminarer Strömung an den Meßraumwänden vorbeiströmende Luft nimmt aus dem Meßraum und insbesondere auch von den Meßraumwänden Wärme auf und führt sie der Klimaeinrichtung 30 zu. Gerade hierdurch wird auf optimale Weise eine präzise einzustellende Meßraumtemperatur erzielt.An air conditioning device 30 is attached above the measuring room ceiling 13 in a manner known per se, through which conditioned air can be supplied to the measuring room 10, which air is circulated in the measuring room 10 and thus brings about temperature compensation. As can be seen from FIG. 4, an air-guiding device in the form of an air-guiding panel 50 is provided below the air-conditioning device 30, which is angled adjacent to an exhaust air opening 60 arranged essentially centrally in the air-conditioning device 30 and on its side facing away from the exhaust air opening 60 with the formation of supply air openings 52 , which are formed between the air baffle 50 and the measuring chamber cover 13 and face the measuring chamber walls 12, ends. The air-conditioned air emitted by the air-conditioning device 30 is directed in laminar flow through this air-guiding panel 50 to the measuring-room walls 12, where it flows downward and is deflected in the area of the measuring-room floor 11, and then again through the exhaust air opening 60 into the air-conditioning device 30 stream, in which it is reprocessed, for example cooled, dusted and cleaned, before it is again supplied to the measuring chamber 10 via the air guide panel 50. The air flowing past the walls of the measuring room in a laminar flow absorbs heat from the measuring room and in particular also from the walls of the measuring room and supplies it to the air conditioning device 30. This is the best way to achieve a precisely adjustable measuring room temperature.
Ein erstes Ausführungsbeispiel einer Vorrichtung zur Klimatisierung von Meßräumen ist detailliert in Fig. 2a,b dargestellt. Wie aus Fig. 2a hervorgeht, ist die Luftleitblende 50 durch Abstandselemente 51 an Deckenträgerelementen 70 befestigt, an welchen auch die Klimaeinrichtung 30 befestigt ist. Die Klimaeinrichtung 30 weist - wie bereits oben erwähnt - eine zentrale Abluftöffnung 60 auf sowie an ihren dem Meßraum 10 zugewandten unteren Enden Luftaustrittsöffnungen 31, durch welche klimatisierte Luft in den durch die Luftleitblende 50 gebildeten Luftleitkanal einströmen kann.A first embodiment of a device for air conditioning measuring rooms is shown in detail in Fig. 2a, b. As can be seen from FIG. 2 a, the air guide panel 50 is fastened to the ceiling support elements 70 by spacing elements 51, to which the air conditioning device 30 is also fastened. As already mentioned above, the air-conditioning device 30 has a central exhaust air opening 60 and, at its lower ends facing the measuring space 10, air outlet openings 31 through which conditioned air can flow into the air guide duct formed by the air guide panel 50.
Das in Fig. 3a,b dargestellte Ausführungsbeispiel unterscheidet sich von dem in Fig. 2 dargestellten dadurch, daß jeweils zwischen der im wesentlichen ebenen Luftleitblende 50 und der Meßraumdecke 13 eine weitere Luftleitblende 80 angeordnet ist, welche zweifach so abgewinkelt ist, daß sich zusammen mit der ebenen Luftleitblende 50 ein Luftführungskanal 87 ergibt, der auf seiner der Klimaeinrichtung 30 zugewandten Seite eine Querschnittsverringerung 83 aufweist, die zu einer Strömung der aus der Klimaeinrichtung 30 austretenden klimatisierten Luft mit höherer Geschwindigkeit führt. An diese Verjüngung 83 anschließend öffnet sich der Luftführungskanal 87 hin zu den Zuluftöffnungen 52, die
zwischen der ebenen Luftleitblende 50 und der Meßraumdecke 13 ausgebildet sind, trichterförmig. In diesem trichterförmigen Bereich weist die ebene Luftleitblende 50 Öffnungen 57 auf, welche die Strömung der klimatisierten Luft in dem Luftführungskanal 87 dadurch optimieren, daß durch sie einströmende Luft mit der in dem Luftführungskanal 87 strömenden Luft vermischt wird. Hierdurch tritt ein Temperaturausgleich der in dem Luftführungskanal 87 strömenden Luft auf. Das Einströmen durch die Öffnungen 57 ermöglicht auf diese Weise bereits eine Termperierung, meistens eine Erwärmung der in dem Luftführungskanal 87 strömenden Luft.The embodiment shown in Fig. 3a, b differs from that shown in Fig. 2 in that between the substantially planar air baffle 50 and the measuring room ceiling 13, a further air baffle 80 is arranged, which is angled twice so that together with the flat air guide panel 50 results in an air duct 87, which on its side facing the air conditioning device 30 has a cross-sectional reduction 83, which leads to a flow of the conditioned air emerging from the air conditioning device 30 at a higher speed. Following this taper 83, the air duct 87 opens to the supply air openings 52 are formed between the flat air baffle 50 and the measuring room ceiling 13, funnel-shaped. In this funnel-shaped area, the flat air guide panel 50 has openings 57 which optimize the flow of the conditioned air in the air duct 87 in that air flowing through it is mixed with the air flowing in the air duct 87. This results in a temperature compensation of the air flowing in the air duct 87. In this way, the inflow through the openings 57 already enables a termination, mostly a heating of the air flowing in the air duct 87.
Auch bei der in Fig. 3 dargestellten Vorrichtung strömt die klimatisierte Luft entlang der Meßraumwände 12 zum Meßraumboden 11 hin, wird dort umgelenkt und durch die Abluftöffnung 60 der Klimaeinrichtung 30 zugeführt, in welcher die so umgewälzte Luft klimatisiert, entstaubt oder auf ähnliche Weise aufbereitet wird.3, the conditioned air flows along the measuring room walls 12 towards the measuring room floor 11, is deflected there and fed through the exhaust air opening 60 to the air conditioning device 30, in which the air circulated in this way is conditioned, dedusted or processed in a similar manner .
Wie insbesondere aus Fig. 1 hervorgeht, weist die Luftleitblende 50 der Vorrichtung zur Klimatisierung von Meßräumen die Gestalt einer die Klimaeinrichtung 30 umgebenden Fläche auf, in welcher die Abluftöffnung 60 angeordnet ist. Hierdurch wird auf einfache Weise ermöglicht, daß die Zuluftöffnungen 52 von der Abluftöffnung 60 möglichst weit entfernt angeordnet sind, wodurch die Umwälzung der Luft in dem Meßraum vorteilhaft verläuft.As can be seen in particular from FIG. 1, the air guide panel 50 of the device for air conditioning measuring rooms has the shape of a surface surrounding the air conditioning device 30, in which the exhaust air opening 60 is arranged. This makes it possible in a simple manner that the supply air openings 52 are arranged as far as possible from the exhaust air opening 60, as a result of which the circulation of the air in the measuring space advantageously proceeds.
Die unterhalb der Meßraumdecke 13 angeordnete Luftleitblende 50 ist dabei so ausgedehnt, daß ihre Überdeckungsfläche größer oder gleich ist als die Fläche, die eine in dem Meßraum 10 angeordneten
Meßeinrichtung, Bearbeitungsmaschine oder dgl. überdeckt.The air baffle 50 arranged below the measuring room ceiling 13 is expanded in such a way that its covering area is greater than or equal to the area that one arranged in the measuring room 10 Measuring device, processing machine or the like. Covered.
Um auch eine Erwärmung der aus den Zuluftöffnungen 52 auströmenden Luft zu erreichen, kann vorgesehen sein, daß zwischen der Meßraumdecke 13 und der Luftleitblende 50 eine Heizeinrichtung angeordnet ist, die vorzugsweise an der Luftleitblende 50 befestigt ist. Durch diese Heizeinrichtung wird eine Erwärmung der dem Meßraum über die Luftleitblende 50 zugeführten Luft ermöglicht.
In order to also heat the air flowing out of the supply air openings 52, it can be provided that a heating device is arranged between the measuring space ceiling 13 and the air guide panel 50, which is preferably attached to the air guide panel 50. This heating device makes it possible to heat the air supplied to the measuring space via the air baffle 50.
