Definitions
- the invention relates to a railroad car with heating or air conditioning, at least one compartment and a basic air duct running under the window of the compartment for supplying heated or air-conditioned basic air to the compartment, which has its own post-heating system, which has at least one connection opening from the basic air duct escaping air flows through and has outlets that cooperate with outflow openings in the compartment arranged under the seats or in the area of the lower window edge, the post-heating system together with the basic air duct being spaced apart by a cover which also contains the duct for air guidance to the outflow openings in the area of the lower window edge is covered, which has recirculation openings in the area between the seats below the seat height, which, together with outlets of the reheating system, open into a channel leading to the outflow openings in the area of the lower window edge, and the outflow openings in this cover are arranged under the seats.
- Such an arrangement has become known, for example, from AT-A-334.417 in connection with a deflection flap which determines the air distribution and whose position is dependent on the air temperature.
- the primary advantage of this arrangement is that the temperature or the flow rate of the basic air can be regulated to a certain pilot value for the entire railroad car by means of rather simple control devices, the individual compartment climate, which is particularly dependent on the occupancy of the passengers, being appropriately reheated without any effect on the others Compartments can be set.
- a disadvantage of the known arrangement is that the readjustment of the temperature depends on the cross section of the various through-flow openings and the given pressure differences and is therefore limited in speed, so that a comfortable climate may only be established relatively late.
- the object of the invention is therefore to achieve the greatest possible rapid and large air throughput while optimally utilizing the existing flow cross-sections in order to achieve the desired air temperature as quickly as possible.
- outflow openings are blown directly behind the nozzle-shaped outlets of the post-heating system, and in that additional recirculating air return openings are arranged directly below the seats and are formed by the outflow openings which are larger than the outlets, with a vacuum area on the outer edge increasing the size trained outflow openings is created.
- the arrangement of the post-heating system together with the basic air duct within a cover which also serves to guide air to the outflow openings on the lower edge of the window, as well as the provision of recirculated air return openings in the area between the seats in this cover per se from AT-A-334.417 is known - as well as by the design and arrangement of the outflow openings under the seats and the additional return flow openings under the seats, there is the essential advantage that the return of compartment air is ensured essentially over the entire width of the compartment and also in the foot area under the seats can contribute to this, especially in the area under the seats, the nozzle-shaped outlets of the post-heating system.
- a railroad car - of which only the area of a compartment 1 is shown - is provided with an air conditioning or heating system, not shown, which supplies heated or air-conditioned basic air to compartment 1 via a basic air duct 2.
- compartment 1 or in any such A separate after-heating system 3 is provided in the compartment, through which air emerging from the basic air duct 2 flows through connection openings 4 and in turn has outlets 5, 5 ′ which cooperate with outflow openings 6, 7, 8 in the compartment 1.
- the air supplied in the basic air duct 2 is regulated by the air conditioning or heating system, not shown, in cooperation with its control with regard to the temperature and possibly also the air volume to a pilot value, which takes into account the external climatic conditions and, under certain circumstances, also the occupation conditions in a pilot compartment.
- the post-heating system 3, which enables additional heating of the preheated or pre-air-conditioned basic air, is used for individual readjustment in each individual compartment.
- a housing 10 is placed on the basic air duct 2 provided with insulating walls 9, the interior of which houses the actual reheating element 11 and is connected to the basic air duct 2 via the connection opening 4.
- the insulating walls 9 can consist, for example, of sheet metal walls with cork cladding; the housing 10 can be designed as a screwed or riveted sheet metal part.
- the basic air duct 2 has - as can be seen in particular from FIG. 4 - in addition to the connection opening 4 to the after-heating system 3, at least one separate outlet opening 12 which, bypassing the after-heating system 3, connects to the outflow opening 8 provided in the region of the upper window edge via an air duct 13 stands.
- the air duct 13 is integrated into the outer wall 14 of the car, but it would also be possible to attach the air channel 13 to the inside of the outer wall 14 of the car.
- the outflow opening 8 can, for example, extend between two air channels 13 drawn upwards on both sides of the window edges 15 over the entire area of the upper edge of the window, which enables outflow at a low speed and avoids any annoyance to the travelers.
- the basic air duct 2 running under the window 16 in the floor area thus supplies basic air via the air ducts 13 to the outflow opening 8 at the top, the temperature of this basic air permitting the heating or air conditioning required if the average compartment occupancy is assumed.
- the blow-out of reheated air required for changing the individual compartment climate takes place on the one hand at the outflow openings 6 under the seats 17 and on the other hand at the outflow opening 7 in the region of the lower window edge.
- the outflow openings 6 under the seats 17 are formed in a cover 18 of the basic air duct 2, which at the same time also serves for guiding compartment air and covers the basic air duct 2 together with the reheating system 3 attached at a distance.
- the outflow openings 6 are directly blown through by the behind, nozzle-shaped outlets 5 of the after-heating system 3, whereby - as can be seen in particular in FIG. 4 - a larger cross-section at the edge of the outflow openings 6 remains free due to the enlarged outlet openings 6 compared to the outlets 5, which consequently remains free of the underpressure which forms there when post-heated air emerges from the post-heating system 3 acts as a return flow opening for compartment air into the interior of the cover 18.
- FIG. 1 and 3 show further backflow openings 19 in the area under the windows in the cover 18, which likewise allow compartment air to enter the inside of the cover 18.
- the compartment circulating air supplied via the return flow openings on the edge of the outflow opening 6 on the one hand and 19 on the other hand is mixed in the region of the outlets 5 ′ (FIG. 3) directed towards the outflow opening 7 with post-heated air emerging from the after-heating system 3 and blown out via the outflow opening 7 at the bottom edge of the window .
- This means that the critical window area is provided with an increased amount of heated air, especially when the outside temperature is low and when it is in heating mode, which increases travel comfort.
- FIG. 1 also folding tables 20, a waste container 21 and parts of the adjustment mechanism 22 for the seats 17 are shown; these parts are omitted in the other figures for the sake of simplicity.

Description
Die Erfindung betrifft einen Eisenbahnwagen mit Heiz- bzw. Klimaanlage, zumindest einem Abteil und einem unter dem Fenster des Abteils verlaufenden Grundluftkanal zur Zufuhr von geheizter bzw. klimatisierter Grundluft zum Abteil, welches eine eigene Nachheizanlage aufweist, die über zumindest eine Verbindungsöffnung von aus dem Grundluftkanal austretender Luft durchströmt ist und Auslässe hat, die mit unter den Sitzen bzw. im Bereich der Fensterunterkante angeordneten Ausströmöffnungen im Abteil zusammenwirken, wobei die Nachheizanlage zusammen mit dem Grundluftkanal von einer auch den Kanal zur Luftführung zu den Ausströmöffnungen im Bereich der Fensterunterkante beinhaltenden Abdeckung mit Abstand überdeckt ist, die im Bereich zwischen den Sitzen unter der Sitzhöhe Umluft Rückströmöffnungen aufweist, die zusammen mit Auslässen der Nachheizanlage in einen zu den Ausströmöffnungen im Bereich der Fensterunterkante führenden Kanal münden, und die Ausströmöffnungen in dieser Abdeckung unter den Sitzen angeordnet sind.The invention relates to a railroad car with heating or air conditioning, at least one compartment and a basic air duct running under the window of the compartment for supplying heated or air-conditioned basic air to the compartment, which has its own post-heating system, which has at least one connection opening from the basic air duct escaping air flows through and has outlets that cooperate with outflow openings in the compartment arranged under the seats or in the area of the lower window edge, the post-heating system together with the basic air duct being spaced apart by a cover which also contains the duct for air guidance to the outflow openings in the area of the lower window edge is covered, which has recirculation openings in the area between the seats below the seat height, which, together with outlets of the reheating system, open into a channel leading to the outflow openings in the area of the lower window edge, and the outflow openings in this cover are arranged under the seats.
Eine derartige Anordnung ist beispielsweise durch die AT-A-334.417 bekannt geworden und zwar im Zusammenhang mit einer die Luftverteilung bestimmenden Umlenkklappe, deren Stellung von der Lufttemperatur abhängig ist. Diese Anordnung bietet primär den Vorteil, daß die Temperatur bzw. auch die Durchströmmenge der Grundluft mittels recht einfacher Regeleinrichtungen für den ganzen Eisenbahnwagen auf einen bestimmten Pilotwert geregelt werden kann, wobei das insbesonders von der Fahrgastbesetzung abhängige individuelle Abteilklima durch entsprechende Nachheizung ohne Auswirkung auf die anderen Abteile eingestellt werden kann. Nachteilig ist bei der bekannten Anordnung allenfalls, daß die Nachregelung der Temperatur vom Querschnitt der diversen Durchströmöffnungen und den gegebenen Druckunterschieden abhängig und damit in ihrer Geschwindigkeit beschränkt ist, so daß sich ein behagliches Klima unter Umständen erst relativ spät einstellt.Such an arrangement has become known, for example, from AT-A-334.417 in connection with a deflection flap which determines the air distribution and whose position is dependent on the air temperature. The primary advantage of this arrangement is that the temperature or the flow rate of the basic air can be regulated to a certain pilot value for the entire railroad car by means of rather simple control devices, the individual compartment climate, which is particularly dependent on the occupancy of the passengers, being appropriately reheated without any effect on the others Compartments can be set. A disadvantage of the known arrangement is that the readjustment of the temperature depends on the cross section of the various through-flow openings and the given pressure differences and is therefore limited in speed, so that a comfortable climate may only be established relatively late.
Die Erfindung hat sich daher die Aufgabe gestellt, unter optimaler Ausnützung der vorhandenen Durchströmquerschnitte einen möglichst raschen und großen Luftdurchsatz zu erzielen, um die gewünschte Lufttemperatur möglichst rasch zu erreichen.The object of the invention is therefore to achieve the greatest possible rapid and large air throughput while optimally utilizing the existing flow cross-sections in order to achieve the desired air temperature as quickly as possible.
Dies wird erfindungegemäß dadurch erzielt, daß die Ausströmöffnungen direkt von dahinterliegenden düsenförmig ausgebildeten Auslässen der Nachheizanlage durchblasen sind, und daß zusätzliche Umluft-Rückströmöffnungen unmittelbar unterhalb der Sitze angeordnet und durch die gegenüber den Auslässen vergrößert ausgebildeten Ausströmöffnungen gebildet sind, wobei ein Unterdruckbereich am Außenrand der vergrößert ausgebildeten Ausströmöffnungen geschaffen wird.This is achieved according to the invention in that the outflow openings are blown directly behind the nozzle-shaped outlets of the post-heating system, and in that additional recirculating air return openings are arranged directly below the seats and are formed by the outflow openings which are larger than the outlets, with a vacuum area on the outer edge increasing the size trained outflow openings is created.
Da - wie eingangs bereits erwähnt - nur ein Teil der über den Grundluftkanal jedem Abteil zugeführten Luft durch die Nachheizanlage strömt, kann diese kleiner und mit geringerer Leistung ausgeführt werden; eine damit allenfalls einhergehende geringfügige Absenkung der Ansprechgeschwindigkeit bei gewünschten bzw. bei geändertem Besetzungsgrad erforderlich werdenden Temperaturänderungen im Abteil läßt sich leicht dadurch kompensieren, daß die schließlich die abteilspezifische Änderung bewirkende nachgeheizte Luft an Stellen ausgeblasen wird, die eine direkte bzw. raschere Wahrnehmung durch den Reisenden sicherstellen - also insbesonders im fußbodennahen Bereich des Abteiles.Since - as already mentioned at the beginning - only a part of the air supplied to each compartment via the basic air duct flows through the post-heating system, this can be made smaller and with a lower output; Any associated slight reduction in the response speed when the temperature changes in the compartment is required or becomes necessary when the degree of occupancy changes. This can easily be compensated for by blowing out the reheated air that finally causes the compartment-specific change in places that provide a direct or faster perception by the traveler ensure - especially in the area of the compartment near the floor.
Durch die Anordnung der Nachheizanlage zusammen mit dem Grundluftkanal innerhalb einer auch zur Luftführung zu den Ausströmöffnungen an der Fensterunterkante dienenden Abdeckung -was ebenso wie die Vorsehung von Umluft-Rückströmöffnungen im Bereich zwischen den Sitzen in dieser Abdeckung an sich aus der genannten AT-A-334.417 bekannt ist - sowie durch die Ausbildung und Anordnung-der Ausströmöffnungen unter den Sitzen und der zusätzlichen Rückströmöffnungen unter den Sitzen ergibt sich der wesentliche Vorteil, daß die Rückführung von Abteilumluft im wesentlichen über die ganze Breite des Abteils und auch im Fußbereich unter den Sitzen sichergestellt werden kann, wozu insbesonders im Bereich unter den Sitzen die düsenförmigen Auslässe der Nachheizanlage aktiv beitragen. Durch diese genannte Anordnung der düsenförmigen Auslässe der Nachheizanlage unterhalb der Sitze wird zusammen mit den dort vorgesehenen, vergrößert ausgebildeten Ausströmöffnungen ein den raschen Luftdrucksatz fördernder Unterdruckbereich am Außenrand der vergrößert ausgebildeten Ausströmöffnungen geschaffen, durch den Abteilumluft ins Innere der Abdeckung und von dort nach Mischung mit aus der Nachheizanlage ausströmender Luft zu den entsprechenden Ausströmöffnungen geführt wird.The arrangement of the post-heating system together with the basic air duct within a cover which also serves to guide air to the outflow openings on the lower edge of the window, as well as the provision of recirculated air return openings in the area between the seats in this cover per se from AT-A-334.417 is known - as well as by the design and arrangement of the outflow openings under the seats and the additional return flow openings under the seats, there is the essential advantage that the return of compartment air is ensured essentially over the entire width of the compartment and also in the foot area under the seats can contribute to this, especially in the area under the seats, the nozzle-shaped outlets of the post-heating system. Through this arrangement of the nozzle-shaped outlets of the after-heating system below the seats, together with the enlarged discharge openings provided there, a vacuum area promoting the rapid air pressure set is created on the outer edge of the enlarged discharge openings, through the compartment air into the inside of the cover and from there after mixing the outflowing air from the post-heating system is led to the corresponding outflow openings.
Die Erfindung wird im folgenden anhand des in der Zeichnung dargestellen Ausführungsbeispiels näher erläutert.The invention is explained below with reference to the embodiment shown in the drawing.
- Fig. 1 zeigt eine teilweise schematische Ansicht eines Abteils eines erfindungsgemäß ausgebildeten Eisenbahnwagens in Richtung zur Fensterseite,1 shows a partially schematic view of a compartment of a railway carriage designed according to the invention in the direction of the window side,
- Fig. 2 zeigt einen teilweisen Schnitt entlang der Linie 11-11 in Fig. 1,Fig. 2 shows a partial section along the line 11-11 in Fig. 1,
- Fig. 3 zeigt einen teilweise schematisch dargestellten Schnitt entlang der Linie 111-111 in Fig. 1 in vergrößertem Maßstab undFig. 3 shows a partially schematically shown section along the line 111-111 in Fig. 1 on an enlarged scale and
- Fig. 4 zeigt einen teilweise schematisch dargestellten Schnitt entlang der Linie IV-IV in Fig. 1 - wiederum in vergrößertem Maßstab.Fig. 4 shows a partially schematic section along the line IV-IV in Fig. 1 - again on an enlarged scale.
Ein Eisenbahnwagen - von dem nur der Bereich eines Abteils 1 dargestellt ist - ist mit einer nicht dargestellten Klima bzw. Heizanlage versehen, die über einen Grundluftkanal 2 geheizte bzw. klimatisierte Grundluft zum Abteil 1 zuführt. Im Abteil 1 bzw. in jedem derartigen Abteil ist eine eigene Nachheizanlage 3 vorgesehen, die über Verbindungsöffnungen 4 von aus dem Grundluftkanal 2 austretender Luft durchströmt ist und ihrerseits Auslässe 5, 5' hat die mit Ausströmöffnungen 6,7,8 im Abteil 1 zusammenwirken.A railroad car - of which only the area of a
Die im Grundluftkanal 2 zugeführte Luft ist von der nicht dargestellten Klima- bzw. Heizanlage in Zusammenwirkung mit deren Regelung bezüglich Temperatur- und gegebenenfalls auch Luftmenge auf einen Pilotwert geregelt, der die äußeren klimatischen Bedingungen sowie unter Umständen auch die Besetzungsbedingungen in einem Pilotabteil berücksichtigt. Zur individuellen Nachregelung in jedem einzelnen Abteil dient die Nachheizanlage 3, welche ein zusätzliches Aufheizen der vorgeheizten bzw. vorklimatisierten Grundluft ermöglicht. Zu diesem Zwecke ist im dargestellten Ausführungsbeispiel auf dem mit Isolierwänden 9 versehenen Grundluftkanal 2 ein Gehäuse 10 aufgesetzt, dessen Innenraum den eigentlichen Nachheizkörper 11 aufnimmt und über die Verbindungsöffnung 4 mit dem Grundluftkanal 2 in Verbindung steht. Die Isolierwände 9 können beispielsweise aus Blechwänden mit Korkverkleidung bestehen; das Gehäuse 10 kann etwa als verschraubter oder vernieteter Blechteil ausgeführt sein.The air supplied in the
Der Grundluftkanal 2 weist-wie insbesonders aus Fig. 4 ersichtlich ist - zusätzlich zur Verbindungsöffnung 4 zur Nachheizanlage 3 noch zumindest eine separate Auslaßöffnung 12 auf, die unter Umgehung der Nachheizanlage 3 mit der im Bereich der Fensteroberkante vorgesehenen Ausströmöffnung 8 über einen Luftkanal 13 in Verbindung steht. Der Luftkanal 13 ist im dargestellten Ausführungsbeispiel in die Wagenaußenwand 14 integriert, jedoch wäre auch durchaus eine auf die Innenseite der Wagenaußenwand 14 aufgesetzte Befestigung des Luftkanals 13 möglich. Die Ausströmöffnung 8 kann sich beispielsweise zwischen zwei an beiden Seiten der Fensterränder 15 nach oben gezogenen Luftkanälen 13 über den ganzen Bereich der Fensteroberkante erstrecken, was eine Ausströmung mit niederer Geschwindigkeit ermöglicht, und jede Belästigung der Reisenden vermeidet.The
Der unter dem Fenster 16 im Fußbodenbereich verlaufende Grundluftkanal 2 liefert also über die Luftkanäle 13 Grundluft zu der obenliegenden Ausströmöffnung 8, wobei die Temperatur dieser Grundluft die bei angenommener mittlerer Abteilbesetzung erforderliche Heizung bzw. Klimatisierung ermöglicht. Die für eine Änderung des individuellen Abteilklimas erforderliche Ausblasung von nachgeheizter Luft erfolgt einerseits an den Ausströmöffnungen 6 unter den Sitzen 17 und andererseits an der Ausströmöffnung 7 im Bereich der Fensterunterkante.The
Die Ausströmöffnungen 6 unter den Sitzen 17 sind in einer Abdeckung 18 des Grundluftkanals 2 ausgebildet, welche gleichzeitig auch zur Führung von Abteilumluft dient und den Grundluftkanal 2 samt aufgesetzter Nachheizanlage 3 mit Abstand überdeckt. Die Ausströmöffnungen 6 werden direkt von den dahinterliegenden, düsenförmig ausgebildeten Auslässen 5 der Nachheizanlage 3 durchblasen, wobei - wie insbesonders in Fig. 4 ersichtlich - durch die gegenüber den Auslässen 5 vergrößert ausgebildeten Auslaßöffnungen 6 ein bestimmter Querschnitt am Rand der Ausströmöffnungen 6 freibleibt, der infolge des sich dort beim Austreten von nachgeheizter Luft aus der Nachheizanlage 3 bildenden Unterdrukkes als Rückströmöffnung für Abteilumluft ins Innere der Abdeckung 18 wirkt. In Fig, 1 und Fig. 3 sind weitere Rückströmöffnungen 19 im Bereich unter den Fenstern in der Abdeckung 18 dargestellt, die ebenfalls einen Eintritt von Abteilumluft ins Innere der Abdeckung 18 ermöglichen. Die über die Rückströmöffnungen am Rand der Ausströmöffnung 6 einerseits bzw, 19 andererseits zugeführte Abteilumluft wird im Bereich der zur Ausströmöffnung 7 gerichteten Auslässe 5' (Fig. 3) mit aus der Nachheizanlage 3 austretender nachgeheizter Luft gemischt und über die Ausströmöffnung 7 an der Fensterunterkante ausgeblasen. Damit ist insbesonders bei niedrigen Außentemperaturen und Heizbetrieb der kritische Fensterbereich mit einer erhöhten Menge an erwärmter Luft versehen, was den Reisekomfort erhöht.The outflow openings 6 under the
Der Vollständigkeit halber ist noch zu erwähnen, daß in Fig. 1 auch Ausklapptische 20, ein Abfallbehälter 21 sowie Teile des Verstellmechanismus 22 für die Sitze 17 dargestellt sind; diese Teile sind in den anderen Fig. der Einfachheit halber weggelassen.For the sake of completeness it should also be mentioned that in FIG. 1 also folding tables 20, a
