Abstract
Description
Vakuum-Isolations-Paneele (VIP) - wie beispielsweise aus DE 198 14 271 A1 und DE 298 09 807 oder DE 298 11 136.5 bekannt - sind bezüglich ihrer Funktionsfähigkeit auf einen dauerhaften Erhalt des einmal eingestellten Vakuums (Restgasdruckes in der Isolierung) angewiesen. Mit ansteigendem Restgasdruck nimmt das Isoliervermögen ab. Ursache für einen Anstieg des Restgasdruckes (Verschlechterung des Vakuums) kann einerseits eine tatsächliche Leckage in der Umhüllung des VIP sein - die u. U. auch bereits durch Fehler bei der Herstellung bedingt ist - andererseits führen andauernde Diffusions- und Permeationsvorgänge durch die Folienumhüllung immer zu einem Druckanstieg und damit zu einer Begrenzung der Lebensdauer des VIP. Vacuum insulation panels (VIP) - such as from DE 198 14 271 A1 and DE 298 09 807 or DE 298 11 136.5 are known - are with regard to their Functionality on permanent maintenance of the vacuum once set (Residual gas pressure in the insulation). With increasing residual gas pressure the insulating ability decreases. Cause of an increase in the residual gas pressure (Worsening of the vacuum) can cause an actual leak in the one hand Serving the VIP - the u. U. also due to manufacturing errors is conditional - on the other hand permanent diffusion and permeation processes lead the film wrapping always leads to an increase in pressure and thus to a Limiting the lifespan of the VIP.
Für den Hersteller der VIP ist es daher wünschenswert oder gar notwendig, die Funktionsfähigkeit der Isolierpaneele und/oder den exakt eingestellten Restgasdruck im VIP am Ende der Fertigungslinie zu bestimmen. Der Anwender derartiger Isolierungen möchte durch laufende oder zyklische Überwachung verlässliche Vorhersagen zur Restlebensdauer treffen können. For the manufacturer of the VIP it is therefore desirable or even necessary that Functionality of the insulation panels and / or the exactly set residual gas pressure to be determined in the VIP at the end of the production line. The user of such Insulations want reliable or ongoing monitoring Can make predictions about the remaining life.
Gängige, aus der Vakuumtechnik bekannte Druckmessmethoden scheiden zur Überwachung von Serienprodukten von vornherein aus, weil derartige Meßsysteme aufwändig und teuer sind und zudem immer mit einem Durchbruch durch die vakuumdichte Umhüllung des VIP - und damit einer zusätzlichen, potentiellen Leckage verbunden sind. Common pressure measurement methods known from vacuum technology are excluded Monitoring of series products from the outset, because such measuring systems are complex and expensive and also always with a breakthrough vacuum-tight wrapping of the VIP - and thus an additional, potential Leakage are connected.
Wegen der physikalisch gegebenen Abhängigkeit und Charakteristik zwischen Druck und spezifischer Wärmeleitfähigkeit ist auch eine Funktionsüberwachung mittels Wärmeleitfähigkeitsmessung und/oder Wärmebildgebungsverfahren sehr aufwändig und deswegen als Qualitätsprüfungsmethode nicht tauglich. Because of the physically given dependency and characteristics between pressure and specific thermal conductivity is also a function monitoring by means of Thermal conductivity measurement and / or thermal imaging method very complex and therefore not suitable as a quality inspection method.
Als relativ einfache Prüfmethode hat sich im Fertigungsbereich bislang ein Verfahren etabliert, bei dem die VIP nach dem Evakuieren und Verschließen in einem Autoklaven mit einem Hüllvakuum beaufschlagt werden. Sobald das umhüllende Vakuum in etwa den Restgasdruck im Innern des VIP erreicht hat, beginnt die Hüllfolie des VIP abzuheben, was beispielsweise über einen Laser gemessen werden kann. Die Methode liefert allerdings nur relativ ungenaue Ergebnisse und keine gesicherten Erkenntnisse bei kleineren Leckagen (oder es müssen längere Lagerzeiten zwischen der Fertigstellung und der Prüfung des VIP eingehalten werden). Außerdem lässt sich ein solches Verfahren nicht zur laufenden Überwachung von bereits im Einsatz befindlichen VIP einsetzen. So far, a method has proven to be a relatively simple test method in the production area established, in which the VIP after evacuation and sealing in one Autoclave with an envelope vacuum. Once the enveloping Vacuum has approximately reached the residual gas pressure inside the VIP, the begins Take off the VIP's wrapping film, which was measured using a laser, for example can be. However, the method only delivers relatively imprecise results and no reliable knowledge in the case of minor leaks (or longer ones are necessary) Storage times between completion and the examination of the VIP are observed become). In addition, such a procedure cannot be carried out Use monitoring of VIPs already in use.
Aufgabe der vorliegenden Erfindung ist es, ein einfaches und kostengünstiges Meßsystem und -Verfahren zu etablieren, welches die Bestimmung des Restgasdruckes im VIP (und damit dessen Funktionsfähigkeit) zu jedem beliebigen Zeitpunkt sowohl nach der Herstellung als auch während des Betriebs ermöglicht. The object of the present invention is a simple and inexpensive Establish measuring system and method, which determines the determination of the Residual gas pressure in the VIP (and thus its functionality) to any one This is possible both after production and during operation.
Versuche haben überraschenderweise gezeigt, dass sich der Restgasdruck im VIP mit hinreichender Genauigkeit aus der Vorspannung der Folienumhüllung der VIP bestimmen lässt. Durch die Differenz aus dem umgebenden Atmosphärendruck und dem Vakuum im innern des VIP verhält sich die Folienumhüllung wie eine eingespannte, belastete Membran. Annähernd gleichbleibenden Umgebungsdruck vorausgesetzt, lässt der Spannungszustand der Folie Rückschlüsse auf den Restgasdruck im VIP zu. Der Spannungszustand der Folie lässt sich zuverlässig z. B. mittels Dehnungsmessstreifen bestimmen. Wird ein solcher Sensor unmittelbar nach der Fertigstellung des VIP auf die Folienumhüllung aufgeklebt, kann dieser Ausgangszustand als optimaler Druck festgehalten werden und Änderungen im Druckzustand sind entsprechend messbar. Surprisingly, tests have shown that the residual gas pressure in the VIP with sufficient accuracy from the pre-tensioning of the film wrapping of the VIP can be determined. By the difference from the surrounding atmospheric pressure and the vacuum inside the VIP, the foil wrapper behaves like one clamped, loaded membrane. Almost constant ambient pressure assuming the tension state of the film allows conclusions to be drawn about the Residual gas pressure in the VIP too. The tension state of the film can be reliably z. B. determine using strain gauges. Will such a sensor immediately after the VIP can be glued to the foil wrapping when it is finished Initial state can be recorded as optimal pressure and changes in the Pressure conditions can be measured accordingly.
Eine weitere Möglichkeit der Bestimmung des Spannungszustandes stellen sogenannte Piezofolien aus hochpolarisiertem Polyvinylfluorid (PVDF) dar. Gegenüber den DMS haben diese Folien im vorliegenden Fall den Vorteil, dass sie einfacher aufgebaut sind und auf dem VIP nicht auftragen. Another possibility to determine the state of tension so-called piezo films made of highly polarized polyvinyl fluoride (PVDF). In the present case, these foils have the advantage over the DMS that they are simpler and do not apply to the VIP.
Derartige Foliensensoren können entweder aufgeklebt oder fest mit der Folienumhüllung des VIP verschweißt werden. Entsprechend dem erwarteten Spannungszustand sowie der erforderlichen Messwertauflösung sind die messaktiven Folien mit Linien- Punkte- oder Matrixrastern zu versehen. Such film sensors can either be glued or fixed to the Foil wrapping of the VIP are welded. According to the expected The voltage state and the required measurement resolution are the to provide measurement-active foils with line, dot or matrix grids.
Wie praktische Versuche ergeben haben, lässt sich die Genauigkeit der Meßmethode und die Signalauswertung weiter verbessern, wenn im Stützkörper des VIP am Applikationsort des Sensors eine Vertiefung eingearbeitet wird, so dass die Folienumhüllung des VIP in diesem Bereich (durch die Druckdifferenz) stärker vorgespannt wird (s. Fig. 1) As practical tests have shown, the accuracy of the measurement method and the signal evaluation can be further improved if a recess is worked into the support body of the VIP at the application site of the sensor, so that the film wrapping of the VIP is pre-tensioned in this area (by the pressure difference) ( see Fig. 1)
Für die eigentliche Messwerterfassung besteht einerseits die Möglichkeit, die Messelektronik direkt am Sensor anzuschließen. Dies bedeutet allerdings, dass die zu überwachenden VIP und deren Meß-Sensoren frei zugänglich sind - die Drucküberwachung ist also in der Regel nicht am eingebauten VIP möglich. On the one hand, there is the possibility for the actual measurement value acquisition Connect measuring electronics directly to the sensor. However, this means that the to be monitored VIP and their measuring sensors are freely accessible - the Pressure monitoring is therefore generally not possible on the built-in VIP.
Deshalb wurde eine andere Möglichkeit der Messwerterfassung untersucht und erprobt. Direkt am Sensor wird ein spezieller Transponder appliziert, der sowohl die Messbrückenschaltung/Verstärker als auch Speichereinheit und Sende-/Empfangs- Antenne beinhaltet. Speisespannung für die Messbrückenschaltung sowie Steuersignale können jetzt von außen mittels einer Sende-/Empfangseinheit übertragen werden und entsprechende Meß-Signale werden auf gleichem Wege empfangen. Außerdem ist ein Vergleich mit den im Transponder gespeicherten Werten aus vergangenen Messperioden möglich. Therefore another possibility of data acquisition was examined and tested. A special transponder is applied directly to the sensor Measuring bridge circuit / amplifier as well as memory unit and transmit / receive Antenna included. Supply voltage for the measuring bridge circuit as well Control signals can now be transmitted from the outside using a transmitter / receiver unit are transmitted and corresponding measurement signals are sent in the same way receive. There is also a comparison with those saved in the transponder Values from past measurement periods possible.
Auf diese Art und Weise ist eine langzeitige Drucküberwachung sowohl an freiliegenden als auch an verbauten VIP möglich. In this way, long-term pressure monitoring is both on Exposed as well as built-in VIP possible.
