Definitions
- the invention relates to a convection drying and / or -fixing machine for the thermal treatment of a web of textile material which is guided transversely to the direction of transport with a treatment gas, which is connected to a fan and which extends above and below the web of material and across the width of the nozzle boxes and one in Flow direction of the treatment gas on each nozzle box following return flow space for circulation of the treatment gas via heat exchangers, fans and nozzle boxes, wherein each of the two fans is mounted in a separate pressure box leading directly to the inlet of the associated nozzle box.
- a separate or independent pressure setting on the upper and lower nozzle box can be achieved if, according to DE-OS 29 08 348, a separate pressure box with fan is assigned to each nozzle box.
- a separate pressure box with fan is assigned to each nozzle box.
- it is provided to provide a pressure chamber with a fan below the lower nozzle box and above the upper nozzle box.
- the air systems of the lower and upper nozzle boxes can be separated from each other, but the overall height of the machine is increased, for example, compared to the case of machines according to the German patent mentioned at the beginning, by at least the vertical dimension of a fan.
- Another DE-PS 29 27 974 describes a device for the continuous shrinking treatment of textile webs, in which nozzle boxes are also provided above and below the textile web, from which the textile web is to be blown simultaneously with a treatment gas from above and below.
- a fan is assigned to each of these nozzle boxes directly at the nozzle box entrance.
- the two fans are one above the other and can be driven by a single motor via a common shaft. This allows the overall height of the entire machine to be reduced, but the arrangement of the fans directly at the nozzle inlet means that either the pressure distribution within the connected nozzle box in the direction of transport of the goods becomes uneven (which would not interfere with the tumbler application according to this patent specification ), or fans with fans must be provided in close succession along the length of the machine with a correspondingly high effort.
- the invention has for its object to design the above-mentioned machine so that an independent control of the pressure, in particular also the temperature, in the lower and upper nozzle box is possible with substantially unchanged overall height and without loss of performance.
- the solution according to the invention for the above-mentioned convection drying and / or fixing machine, in which each of the two fans is mounted in a separate, directly - and essentially only - pressure inlet leading to the inlet of one of the nozzle boxes, is that the two Fans are arranged at substantially the same height above the floor below the level of the lower nozzle box within the inlet parts of the associated pressure boxes, that the two pressure box inlet parts extend next to one another at approximately the same height, essentially over the entire nozzle box extension measured in the transport direction, and that the fan of the pressure box inlet section cut off from the backflow chamber has an intake pipe leading through the other pressure box inlet section to the backflow chamber.
- two fans are thus arranged in separate pressure boxes in the space below the height of the lower nozzle box.
- the two fans are roughly in the same range as in the case of DE-PS 36 27 904, but they are offset from one another in the direction transverse to the transport direction of the fabric web to be treated, so that each of the fans can move about the (in the Direction of pressure measured) the entire length of the nozzle box can lead from the fan to the nozzle box.
- Such a pressure box ensures an even pressure distribution at the nozzle box inlet.
- the one pressure box is cut off from the direct access to the return flow space by the other pressure box for reasons of geometry.
- a passage through the pressure box inlet part facing the return flow space is provided according to the invention and is designed as an intake pipe of the fan mounted in the other pressure box inlet part. Since each of the fans does not require more volume for the air delivery than previously for supplying the two nozzle boxes together, no more space is required for the pressure boxes in the direction transverse to the transport direction than according to the prior art.
- both nozzle boxes have a common return flow space and a common heating via heat exchangers, a separate temperature setting on the top and bottom of the fabric web to be treated cannot be easily achieved.
- the backflow spaces of the upper and lower nozzle boxes are separated from one another and have separate connections, each with a heat exchanger, to the pressure box inlets.
- the return gas coming from the lower and upper nozzle box is conducted in separate ways via separate heat exchangers to the area below the lower nozzle box and is fed there to the two fans via separate channels.
- a vertical section perpendicular to the longitudinal direction of the machine which is designed in the embodiment as a so-called clamping frame, is shown schematically.
- the fabric web 1 to be treated is held in chains 2 and 3 at its longitudinal edges in the transport direction of the fabric web, that is to say in the direction perpendicular to the plane of the drawing, between two nozzle boxes 4 and 5.
- One nozzle box namely the upper nozzle box 4
- the other nozzle box namely the lower nozzle box 5
- the nozzle boxes 4 and 5 have (not shown) hole or slot nozzles Blowing out treatment gas in the direction of arrow 6 from above and below onto the fabric web 1.
- the treatment gas is conveyed by means of two fans 7 and 8 in the direction of arrows 9 and 10 into a pressure box 11 and 12 upstream of the nozzle boxes 4 and 5 and reaches the normal operation of the Machine into the nozzle boxes 4 and 5 through the pressure box outputs assigned to the nozzle box inlets 13 and 14.
- the fans 7 and 8 should have independently controllable motors 15 and 16. From there, the treatment gas flows in the direction of the arrow 6 onto the fabric web 1 and from it essentially in the direction of the arrow 17 and 18 into the return flow space of the machine, generally designated 19, and from there via a heat exchanger or the like, generally designated 20 in the direction of the arrow 21 and 22 the suction side of the respective fan 7 or 8 supplied.
- the two fans 7 and 8 according to FIGS. 1 to 3 are arranged essentially at the same height above the floor 23 below the level of the lower nozzle box 5 within the inlet parts 24 and 25 of the pressure boxes 11 and 12. 1, the fan wheels 7, 8 are offset one behind the other in the direction of their axes, and in FIG. 3 they are adjacent to one another at the same height.
- the two pressure box inlet parts 24, 25 extend at approximately the same height next to one another essentially over the entire nozzle box extension measured in the transport direction 26 (FIG. 2) of the fabric web 1. In this way, the front pressure box input part 24 cuts off the rear pressure box input part 25 from the backflow space 19 itself.
- the formation of the print box input parts 24 and 25 and the print boxes 11 and 12 over the entire length of the print box extending in the transport direction 26 is important in order to achieve a uniform pressure distribution over the length of the print box at the print box exit or at the print box input 13 and 14.
- These contradicting conditions are solved according to the invention in the following way: through a passage through the pressure chamber 24 designed as a suction pipe 27 (FIG. 2), the treatment medium (including air) flows from the backflow chamber 19 to the fan 8 of the rear pressure box inlet part 25.
- a suction pipe 27 interferes the air flow within the front pressure box inlet part 24 is not, so that a pressure distribution can be achieved in both nozzle boxes 4 and 5, which can be individually varied in any manner and is uniformly adjustable over the entire pressure box area.
- the temperature in the upper and lower pressure boxes 4, 5 is to be regulated separately, according to another Invention provided to divide the backflow chamber 19 into separate backflow subspaces 28 for the upper pressure box 4 and 29 for the lower pressure box 5.
- the heat exchanger 20 is divided into two partial heat exchangers 30 and 31 for the backflow partial spaces 28 and 29.
Abstract
Description
Die Erfindung betrifft eine Konvektions-Trocken- und/oder -fixiermaschine zum thermischen Behandeln einer quer zur Transportrichtung breitgeführten textilen Stoffbahn mit einem Behandlungsgas, welche an je einen Ventilator angeschlossene, sich ober- und unterhalb der Stoffbahn quer zu deren Breite erstreckende Düsenkästen und einen in Strömungsrichtung des Behandlungsgases auf jeden Düsenkasten folgenden Rückströmraum für eine Umwälzung des Behandlungsgases über Wärmetauscher, Ventilatoren und Düsenkästen aufweist, wobei jeder der beiden Ventilatoren in einem gesonderten, unmittelbar zum Einlaß des zugeordneten Düsenkastens führenden Druckkasten montiert ist.The invention relates to a convection drying and / or -fixing machine for the thermal treatment of a web of textile material which is guided transversely to the direction of transport with a treatment gas, which is connected to a fan and which extends above and below the web of material and across the width of the nozzle boxes and one in Flow direction of the treatment gas on each nozzle box following return flow space for circulation of the treatment gas via heat exchangers, fans and nozzle boxes, wherein each of the two fans is mounted in a separate pressure box leading directly to the inlet of the associated nozzle box.
Eine Maschine dieser Art mit mindestens einem Ventilator, der einem für den unteren und oberen Düsenkasten gemeinsamen Druckraum zugeordnet ist, wird in der DE-PS 36 27 904 beschrieben.A machine of this type with at least one fan, which is assigned to a common pressure chamber for the lower and upper nozzle box, is described in DE-PS 36 27 904.
Eine getrennte bzw. unabhängige Druckeinstellung am oberen und unteren Düsenkasten läßt sich erreichen, wenn nach der DE-OS 29 08 348 jedem Düsenkasten ein gesonderter Druckkasten mit Ventilator zugeordnet wird. Im Bekannten wird vorgesehen, unterhalb des unteren Düsenkastens und oberhalb des oberen Düsenkastens je einen Druckraum mit Ventilator vorzusehen. Auf diese Weise lassen sich die Luftsysteme des unteren und oberen Düsenkastens zwar voneinander trennen, die Bauhöhe der Maschine wird aber beispielsweise gegenüber dem Fall, der Maschinen nach der eingangs genannten deutschen Patentschrift, mindestens um die vertikale Abmessung eines Ventilators erhöht.A separate or independent pressure setting on the upper and lower nozzle box can be achieved if, according to DE-OS 29 08 348, a separate pressure box with fan is assigned to each nozzle box. In the known, it is provided to provide a pressure chamber with a fan below the lower nozzle box and above the upper nozzle box. In this way, the air systems of the lower and upper nozzle boxes can be separated from each other, but the overall height of the machine is increased, for example, compared to the case of machines according to the German patent mentioned at the beginning, by at least the vertical dimension of a fan.
In einer weiteren DE-PS 29 27 974 wird eine Vorrichtung zur kontinuierlichen Schrumpfbehandlung von Textilbahnen beschrieben, bei der ebenfalls ober- und unterhalb der Textilbahn Düsenkästen vorgesehen werden, aus denen die Textilbahn mit einem Behandlungsgas von oben und unten gleichzeitig zu beblasen ist. Jedem dieser Düsenkästen wird ein Ventilator unmittelbar am Düsenkasteneingang zugeordnet. Die beiden Ventilatoren liegen übereinander und können über eine gemeinsame Welle von einem einzigen Motor angetrieben werden. Dadurch läßt sich die Bauhöhe der ganzen Maschine zwar reduzieren, die Anordnung der Ventilatoren unmittelbar am Düseneingang hat aber zur Folge, daß entweder die Druckverteilung innerhalb des angeschlossenen Düsenkastens in Transportrichtung der Ware ungleichmäßig wird (was bei der Tumbler-Anwendung nach dieser Patentschrift nicht stören würde), oder es müssen Gebläse mit Ventilatoren in dichter Folge auf der Länge der Maschine mit entsprechend hohem Aufwand vorgesehen werden.Another DE-PS 29 27 974 describes a device for the continuous shrinking treatment of textile webs, in which nozzle boxes are also provided above and below the textile web, from which the textile web is to be blown simultaneously with a treatment gas from above and below. A fan is assigned to each of these nozzle boxes directly at the nozzle box entrance. The two fans are one above the other and can be driven by a single motor via a common shaft. This allows the overall height of the entire machine to be reduced, but the arrangement of the fans directly at the nozzle inlet means that either the pressure distribution within the connected nozzle box in the direction of transport of the goods becomes uneven (which would not interfere with the tumbler application according to this patent specification ), or fans with fans must be provided in close succession along the length of the machine with a correspondingly high effort.
Der Erfindung liegt die Aufgabe zugrunde, die eingangs genannte Maschine so auszubilden, daß bei im wesentlichen unveränderter Bauhöhe und ohne Leistungseinbuße eine unabhängige Steuerung des Drucks, insbesondere auch der Temperatur, im unteren und oberen Düsenkasten möglich ist.The invention has for its object to design the above-mentioned machine so that an independent control of the pressure, in particular also the temperature, in the lower and upper nozzle box is possible with substantially unchanged overall height and without loss of performance.
Die erfindungsgemäße Lösung besteht für die eingangs genannte Konvektions-Trocken- und/oder -fixiermaschine, in der jeder der beiden Ventilatoren in einem gesonderten, unmittelbar - und im wesentlichen nur - zum Einlaß eines der Düsenkästen führenden Druckkasten montiert ist, darin, daß die beiden Ventilatoren in wesentlichen in gleicher Höhe über Boden unterhalb des Niveaus des unteren Düsenkastens innerhalb von Eingangsteilen der zugehörigen Druckkästen angeordnet sind, daß die beiden Druckkasteneingangsteile sich auf etwa gleicher Höhe nebeneinander im wesentlichen über die ganze, in der Transportrichtung gemessene, Düsenkastenausdehnung erstrecken und daß der Ventilator des vom Rückströmraum abgeschnittenen Druckkasteneingangsteils ein durch den anderen Druckkasteneingangteil führendes Ansaugrohr zum Rückströmraum besitzt.The solution according to the invention for the above-mentioned convection drying and / or fixing machine, in which each of the two fans is mounted in a separate, directly - and essentially only - pressure inlet leading to the inlet of one of the nozzle boxes, is that the two Fans are arranged at substantially the same height above the floor below the level of the lower nozzle box within the inlet parts of the associated pressure boxes, that the two pressure box inlet parts extend next to one another at approximately the same height, essentially over the entire nozzle box extension measured in the transport direction, and that the fan of the pressure box inlet section cut off from the backflow chamber has an intake pipe leading through the other pressure box inlet section to the backflow chamber.
Erfindungsgemäß werden also in dem Raum unterhalb der Höhe des unteren Düsenkastens zwei Ventilatoren in getrennten Druckkästen angeordnet. Die beiden Ventilatoren liegen in etwa im selben Bereich wie im Fall der DE-PS 36 27 904, sie sind aber in Richtung quer zur Transportrichtung der zu behandelnden Stoffbahn gegeneinander so versetzt, daß sich von jedem der Ventilatoren aus ein sich über die (in der Transportrichtung gemessene) gesamte Lange des Düsenkastens erstreckender Druckkasten vom Ventilator zum Düsenkasten führen kann. Ein solcher Druckkasten gewahrleistet eine gleichmäßige Druckverteilung an Düsenkasteneingang. Bei der erfindungsgemäßen Konstruktion wird der eine Druckkasten aus Gründen der Geometrie durch den anderen Druckkasten von dem unmittelbaren Zugang zum Rückströmraum abgeschnitten. Um diesem Problem zu begegnen, wird erfindungsgemäß eine Durchführung durch den dem Rückströmraum zugewandten Druckkasteneingangsteil vorgesehen und als Ansaugrohr des im anderen Druckkasteneingangsteil montierten Ventilators ausgebildet. Da für die Luftförderung jeder der Ventiloren nicht mehr Volumen benötigt wird als früher für die Versorgung beider Düsenkästen zusammen, wird für die Druckkästen auch in Richtung quer zur Transportrichtung nicht mehr Platz als nach dem Stand der Technik benötigt.According to the invention, two fans are thus arranged in separate pressure boxes in the space below the height of the lower nozzle box. The two fans are roughly in the same range as in the case of DE-PS 36 27 904, but they are offset from one another in the direction transverse to the transport direction of the fabric web to be treated, so that each of the fans can move about the (in the Direction of pressure measured) the entire length of the nozzle box can lead from the fan to the nozzle box. Such a pressure box ensures an even pressure distribution at the nozzle box inlet. In the construction according to the invention, the one pressure box is cut off from the direct access to the return flow space by the other pressure box for reasons of geometry. In order to counter this problem, a passage through the pressure box inlet part facing the return flow space is provided according to the invention and is designed as an intake pipe of the fan mounted in the other pressure box inlet part. Since each of the fans does not require more volume for the air delivery than previously for supplying the two nozzle boxes together, no more space is required for the pressure boxes in the direction transverse to the transport direction than according to the prior art.
Auch bei bereits in der Praxis eingeführten Maschinen nach der DE-PS 36 27 904 werden im Bereich unterhalb des unteren Düsenkastens zwei Ventilatoren - freilich in einem gemeinsamen einheitlichen Druckraum - vorgesehen, um die nötige Ventilatorleistung mit wirtschaftlich vertretbarem Aufwand zu erreichen. Hierzu kommt erfindungsgemäß als Aufwand zur Lösung der Aufgabe hinzu, daß der einheitliche Druckraum in zwei getrennte Druckräume zu unterteilen ist, daß der dadurch vom Rückströmraum abgeschnittene Druckkasten mit einem durch den anderen Druckraum führenden Ansaugrohr ausgestattet wird, und daß die beiden Ventilatoren den zugehörigen Druckräumen entsprechend gegenseitig um etwa eine Ventilatorlänge zu versetzen sind. Mit Hilfe der beiden getrennten Druckräume läßt sich eine entsprechend unabhängige Druckeinstellung in den beiden Düsenkästen erreichen. Wenn jedoch, was in erster Linie vorgesehen ist, beide Düsenkästen einen gemeinsamen Rückströmraum und eine gemeinsame Heizung über Wärmetauscher besitzen, läßt sich eine getrennte Temperatureinstellung auf der Ober-und Unterseite der zu behandelnden Stoffbahn nicht ohne weiteres erreichen. Das wird gemäß weiterer Erfindung möglich, wenn die Rückströmräume des oberen und unteren Düsenkastens voneinander getrennt sind und getrennte Verbindungen mit je einem Wärmetauscher zu den Druckkasteneingängen besitzen. Bei dieser weiteren Ausgestaltung der Erfindung kann bevorzugt vorgesehen werden, das vom unteren und oberen Düsenkasten kommende Rückströmgas auf getrennten Wegen über getrennte Wärmetauscher in den Bereich unterhalb des unteren Düsenkastens zu leiten und dort über getrennte Kanäle den beiden Ventilatoren zuzuführen.Even with machines already introduced in practice according to DE-PS 36 27 904, two fans are provided in the area below the lower nozzle box - albeit in a common, uniform pressure chamber - in order to achieve the necessary To achieve fan performance with economically justifiable effort. To this end, according to the invention, there is an additional effort to solve the problem that the uniform pressure chamber is to be divided into two separate pressure chambers, that the pressure box cut off from the return flow chamber is equipped with an intake pipe leading through the other pressure chamber, and that the two fans correspond to the associated pressure chambers are mutually offset by about one fan length. With the help of the two separate pressure chambers, a correspondingly independent pressure setting can be achieved in the two nozzle boxes. If, however, what is primarily provided, both nozzle boxes have a common return flow space and a common heating via heat exchangers, a separate temperature setting on the top and bottom of the fabric web to be treated cannot be easily achieved. This is possible according to another invention if the backflow spaces of the upper and lower nozzle boxes are separated from one another and have separate connections, each with a heat exchanger, to the pressure box inlets. In this further embodiment of the invention, it can preferably be provided that the return gas coming from the lower and upper nozzle box is conducted in separate ways via separate heat exchangers to the area below the lower nozzle box and is fed there to the two fans via separate channels.
Anhand der schematischen Darstellung in der beiliegenden Zeichnung werden Einzelheiten der Erfindung erläutert. Es zeigen:
- Fig. 1 einen Schnitt durch eine Konvektions-Trocken- und/oder -fixiermaschine quer zur Transportrichtung einer zu behandelnden Stoffbahn;
- Fig. 2 einen Schnitt längs der Linie 11-11 von Fig. 1; und
- Fig. 3 einen Schnitt längs der Linie 111-111 von Fig.
- 1 shows a section through a convection drying and / or fixing machine transversely to the transport direction of a fabric web to be treated;
- Fig. 2 is a section along the line 11-11 of Fig. 1; and
- 3 shows a section along the line 111-111 of FIG.
In Fig. 1 wird ein vertikaler Schnitt senkrecht zur Längsrichtung der Maschine, die im Ausführungsbeispiel als sogenannter Spannrahmen ausgebildet ist, schematisch dargestellt. Bei Betrieb des Spannrahmens wird die zu behandelnde Stoffbahn 1 in Ketten 2 und 3 an ihren Längsrändern gehalten in der Transportrichtung der Stoffbahn, das heißt in Richtung senkrecht zur Zeichnungsebene, zwischen zwei Düsenkästen 4 und 5 hindurchgeführt. Der eine Düsenkasten, nämlich der obere Düsenkasten 4, befindet sich oberhalb der Stoffbahn 1, und der andere Düsenkasten, nämlich der untere Düsenkasten 5, befindet sich unterhalb der Stoffbahn 1. Die Düsenkästen 4 und 5 besitzen (nicht gezeichnete) Loch- oder Schlitzdüsen zum Ausblasen von Behandlungsgas in Pfeilrichtung 6 von oben und unten auf die Stoffbahn 1. Das Behandlungsgas wird mit Hilfe von zwei Ventilatoren 7 und 8 in Pfeilrichtung 9 und 10 in je einen den Düsenkästen 4 und 5 vorgeschalteten Druckkasten 11 und 12 gefördert und gelangt bei Normalbetrieb der Maschine durch die den Düsenkasteneingängen 13 und 14 zugeordneten Druckkastenausgänge in die Düsenkästen 4 und 5 hinein. Die Ventilatoren 7 und 8 sollen unabhängig voneinander steuerbare Motoren 15 und 16 besitzen. Von dort fließt das Behandlungsgas in Pfeilrichtung 6 auf die Stoffbahn 1 und wird von dieser im wesentlichen in Pfeilrichtung 17 und 18 in den insgesamt mit 19 bezeichneten Rückströmraum der Maschine und von dort über einen insgesamt mit 20 bezeichneten Wärmetauscher oder dergleichen in Pfeilrichtung 21 bzw. 22 der Saugseite des jeweiligen Ventilators 7 oder 8 zugeführt.In Fig. 1, a vertical section perpendicular to the longitudinal direction of the machine, which is designed in the embodiment as a so-called clamping frame, is shown schematically. When the tenter frame is operated, the
Erfindungsgemäß werden die beiden Ventilatoren 7 und 8 nach Fig. 1 bis 3 im wesentlichen in gleicher Höhe über Boden 23 unterhalb des Niveaus des unteren Düsenkastens 5 innerhalb von Eingangsteilen 24 bzw. 25 der Druckkästen 11 und 12 angeordnet. In der Ansicht nach Fig. 1 liegen also die Ventilatorräder 7, 8 versetzt in Richtung ihrer Achsen hintereinander, und in Fig. 3 liegen sie auf gleicher Höhe nebeneinander. Die beiden Druckkasteneingangsteile 24, 25 erstrecken sich auf etwa gleicher Höhe nebeneinander im wesentlichen über die ganze, in der Transportrichtung 26 (Fig. 2) der Stoffbahn 1 gemessene Düsenkastenausdehnung. Auf diese Weise schneidet das vordere Druckkasteneingangsteil 24 das hintere Druckkasteneingangsteil 25 vom Rückströmraum 19 an sich ab. Die Ausbildung der Druckkasteneingangsteile 24 und 25 sowie der Druckkästen 11 und 12 über die ganze sich in Transportrichtung 26 erstreckende Druckkastenlänge ist aber wichtig, um am Druckkastenausgang bzw. am Druckkasteneingang 13 und 14 eine über die Druckkastenlänge gleichmäßige Druckverteilung zu erreichen. Diese sich widersprechenden Bedingungen werden erfindungsgemäß in folgender Weise gelöst: Durch eine als Ansaugrohr 27 (Fig. 2) ausgebildete Durchführung durch den Druckraum 24 strömt das Behandlungsmedium (u.a. Luft) vom Rückströmraum 19 zum Ventilator 8 des hinteren Druckkasteneingangsteils 25. Ein solches Ansaugrohr 27 stört die Luftführung innerhalb des vorderen Druckkasteneingangsteils 24 nicht, so daß in beiden Düsenkästen 4 und 5 eine Druckverteilung erreichbar ist, die in beliebiger Weise einzeln variierbar und über die ganze Druckkastenfläche gleichmäßig einstellbar ist.According to the invention, the two
Wenn außer der Druckverteilung auch die Temperatur im oberen und unteren Druckkasten 4, 5 getrennt geregelt werden soll, wird gemäß weiterer Erfindung vorgesehen, den Rückströmraum 19 in getrennte Rückströmteilräume 28 für den oberen Druckkasten 4 und 29 für den unteren Druckkasten 5 zu unterteilen. Entsprechend wird der Wärmetauscher 20 in zwei Teil-Wärmetauscher 30 und 31 für die Rückströmteilräume 28 und 29 unterteilt. Außerdem werden zusätzlich zu einer horizontalen Trennwand 32, die zum Leiten der rückströmenden Gase durch den Wärmetauscher 20 ohnehin erforderlich ist, weitere Trennwände 33 vorgesehen, die eine getrennte Führung des rückströmenden Behandlungsgases in Pfeilrichtung 17 vom unteren Druckkasten 5 über den Teil-Wärmetauscher 31 zum Ventilator 7 und vom oberen Druckkasten 4 in Pfeilrichtung 18 durch den Teil-Wärmetauscher 30 zum Ventilator 8 sicherstellen.If, in addition to the pressure distribution, the temperature in the upper and
