Description

Beschreibung description
Klimatisierungsanordnung für ein Schienenfahrzeug Air conditioning arrangement for a rail vehicle
Die Erfindung bezieht sich auf eine Klimatisierungsanordnung für ein Schienenfahrzeug, mit einer Luftverteilbox, die einen Lufteinlass und wenigstens zwei Luftauslässe zum Anschluss an weiterführende Luftkanäle aufweist. Luftverteilboxen und an- dere Komponenten mit Luverteileigenschaften, wie Schalldämpfer, werden in Schienenfahrzeugen benutzt, um verschiedene Teile des Luftkanalsystems mit den benötigten Luftmengen zu versorgen. Luftverteilboxen stellen dabei regelmäßig die Schnittstelle zu einem Klimagerät, insbesondere Kompaktklima- gerät, dar, das der Luftverteilbox über den Lufteinlass auf¬ bereitete Luft zuführt. The invention relates to an air conditioning arrangement for a rail vehicle, having an air distribution box, which has an air inlet and at least two air outlets for connection to further air ducts. Air distribution boxes and other components having air vents, such as mufflers, are used in rail vehicles to supply various parts of the air duct system with the required air volumes. Luftverteilboxen provide regularly be the interface to an air conditioner, particularly Kompaktklima- device, is that supplies of Luftverteilbox via the air intake on ¬ prepared air.
Die Luftverteilbox kann ihre Luftverteilfunktion allerdings nicht für eine Vielfalt unterschiedlicher Schienenfahrzeuge und damit auch verschiedene Luftkanalanordnungen übernehmen. Daher wird bei bekannten Luftkanalanordnungen je nach Schienenfahrzeugwagenkonfiguration an der Luftverteilbox eine Einstellung durch Drosselung an den Luftauslässen vorgenommen. Eine vorgenommene Einstellung wird dann durch Versuche bei- spielsweise in einer Klimakammer überprüft, bis die geeignete Einstellung für die vorliegende Schienenfahrzeugausführung gefunden ist. Dabei führen nichtlineare Eigenschaften der typischerweise komplexen Luftkanalanordnung zu einer hohen Anzahl an Versuchsschritten. However, the Luftverteilbox can not take over their air distribution function for a variety of different rail vehicles and thus also different air duct arrangements. Therefore, in known air duct arrangements, depending on the railcar configuration at the air distribution box, adjustment is made by throttling at the air outlets. A setting made is then checked by tests, for example in a climatic chamber, until the appropriate setting for the present rail vehicle version is found. Nonlinear properties of the typically complex air duct arrangement lead to a high number of test steps.
Ausgehend hiervon liegt der Erfindung die Aufgabe zugrunde, eine Klimatisierungsanordnung der eingangs genannten Art derart weiterzuentwickeln, dass das Auffinden der geeigneten Einstellung für die Drosselung an den Luftauslässen der Proceeding from this, the invention has the object, an air conditioning arrangement of the type mentioned in such a way that finding the appropriate setting for throttling at the air outlets of
Luftverteilbox hinsichtlich ihres Aufwands vermindert wird. Air distribution box is reduced in terms of their effort.
Diese Aufgabe wird bei der eingangs genannten Klimatisie¬ rungsanordnung dadurch gelöst, dass jedem Luftauslass eine Drosseleinrichtung zugeordnet ist, die zwischen dem Luftaus- lass und einem Luftaufteilungsraum innerhalb der This object is achieved in the above-mentioned air conditioning ¬ arrangement in that each air outlet a Assigned throttle device that between the air outlet and an air distribution space within the
Luftverteilbox, in dem der von dem Lufteinlass kommende Luft¬ strom auf wenigstens zwei Teil-Luftströme aufgeteilt wird, angeordnet ist, wobei Druckverlustbeiwerte der wenigstens zwei Drosseleinrichtungen derart gewählt sind, dass sich für ein Verhältnis von Luftvolumenströmen an den wenigstens zwei Luftauslässen ein vorgegebener Wert ergibt. Luftverteilbox, in which the air coming from the air inlet air ¬ stream is divided into at least two partial air streams is arranged, wherein Druckverlustbeiwerte the at least two throttle devices are selected such that there is a predetermined value for a ratio of air flow rates at the at least two air outlets ,
Der Einsatz der den jeweiligen Luftauslässen zugeordneten Drosseleinrichtungen ermöglicht es, für das Verhältnis der Luftvolumenströme an den Luftauslässen eine Grobeinstellung vorzunehmen, so dass bei ein- und derselben Luftverteilbox, eingesetzt in verschiedenen Schienenfahrzeugen mit verschiedenen Luftkanalanordnungen lediglich noch Feinj ustierungen für Drosselungen stromabwärts der Luftauslässe erforderlich sind. Dies vermindert den Aufwand hinsichtlich der Einstel¬ lung der Luftkanalanordnung, um gewünschte Luftvolumenströme in den weiterführenden Luftkanälen zu erhalten. The use of the respective air outlets associated throttle devices makes it possible to make a coarse adjustment for the ratio of the air volume flows at the air outlets, so that in one and the same Luftverteilbox used in various rail vehicles with different air duct arrangements only Feinj ustierungen for throttling downstream of the air outlets are required , This reduces the effort in terms of the SET ¬ development of the air duct assembly, to obtain desired air flow rates in the secondary air ducts.
Die Druckverlustbeiwerte der wenigstens zwei Drosseleinrich¬ tungen stehen typischer Weise in einem Verhältnis zueinander, das einem quadratischen Verhältnis von Luftströmungsgeschwindigkeiten im Bereich der wenigstens zwei Luftauslässe ent¬ spricht. In dieser Weise lassen sich die erforderlichen The pressure loss coefficients of the at least two Drosseleinrich ¬ obligations are typically each other in a ratio which speaks ent ¬ a square ratio of air flow velocities in the region of at least two air outlets. In this way, the required
Druckverlustbeiwerte anhand der jeweils an den Luftauslässen gewünschten Strömungsgeschwindigkeiten ableiten. Derive pressure loss coefficients on the basis of the respectively desired at the air outlets flow rates.
Die Druckverlustbeiwerte der wenigstens zwei Drosseleinrich- tungen können derart gewählt sein, dass ein jeweils an denThe pressure loss coefficients of the at least two throttle devices may be selected such that a respective one of the
Drosseleinrichtungen auftretender Druckverlust wenigstens dem Doppelten des Druckverlustes eines an den Luftauslass ange¬ schlossenen Luftkanalsystems entspricht. Dieser Druckverlust an den Drosseleinrichtungen kann auch einem Vielfachen des Druckverlusts des an den Luftauslass angeschlossenen Luftka¬ nalsystems entsprechen. Diese Vorgehensweise hat den Vorteil, dass die Drosseleinrichtungen nichtlineare Eigenschaften der Luftvolumenströme verringern und somit auch unvorhersehbare Effekte für die Feineinstellung der Luftvolumenströme an den Luftauslassen . Throttle devices occurring pressure loss corresponds to at least twice the pressure loss of an attached to the air outlet ¬ closed air duct system. This pressure loss in the reactor means may also correspond to a multiple of the pressure loss of the connected to the air outlet Luftka ¬ nalsystems. This approach has the advantage that the throttle devices reduce non-linear properties of the air flow rates and thus also unpredictable Effects for the fine adjustment of the air volume flows at the air outlets.
Beispielsweise können die Luftdruckverlustbeiwerte der we- nigstens zwei Drosseleinrichtungen jeweils größer als 7 sein. Dieser Wert gewährleistet, dass der Druckverlust an der be¬ treffenden Drosseleinrichtung im Regelfall bei Schienenfahrzeugen größer ist als der Druckverlust weiterführender Luftkanäle . For example, the Luftdruckverlustbeiwerte of at least two throttle devices may each be greater than 7. This value ensures that the pressure loss at the respective throttle device is generally greater in the case of rail vehicles than the pressure loss of continuing air ducts.
Die wenigstens zwei Drosseleinrichtungen können bevorzugt je¬ weils von einer Lochplatte gebildet sein. Dabei können die Lochplatten ein Verhältnis von Plattenstärke zu Lochdurchmes¬ ser von mehr als 1,5 aufweisen. Dies hat den Vorteil, dass die Lochplatten die Wirkung eines Gleichrichters entfalten, so dass die Einwirkung nicht linearer Eigenschaften der Luftströmungen weiter vermindert wird. Auch werden ungünstige Effekte von Ablösungen an Heiz-/Kühlklappen, mit denen The at least two throttle means may be preferably formed, depending ¬ weils of a perforated plate. The perforated plates may have a ratio of plate thickness to Lochdurchmes ¬ ser of more than 1.5. This has the advantage that the perforated plates unfold the effect of a rectifier, so that the influence of non-linear properties of the air flows is further reduced. Also, unfavorable effects of deletions on heating / cooling flaps, with which
Luftverteilboxen regelmäßig ausgestattet sind, durch die Gleichrichterfunktion der Lochplatten wirksam verringert. Air distribution boxes are regularly equipped, effectively reduced by the rectifier function of the perforated plates.
Zwischen dem Lufteinlass und dem Luftaufteilungsraum kann eine Schalldämpfeinrichtung vorgesehen sein. Solche Schalldämpfeinrichtungen sind idealerweise derart ausgelegt, dass Verwirbelungen der Luftströmung vermindert werden. Bevorzugt kann dabei die Schalldämpfeinrichtung derart ausgebildet sein, dass ein von dem Lufteinlass kommender Luftstrom auf mehrere, nebeneinander angeordnete Strömungsstrecken verteilt und hinter der Schalldämpfeinrichtung wieder zusammengeführt wird. Hieraus ergibt sich eine Luftverteilfunktion der A sound damping device may be provided between the air inlet and the air distribution space. Such Schalldämpfeinrichtungen are ideally designed so that turbulence of the air flow are reduced. In this case, the sound damping device may preferably be designed in such a way that an air flow coming from the air inlet is distributed over a plurality of flow paths arranged next to one another and brought together again behind the sound damping device. This results in an air distribution function of
Schalldämpfeinrichtung, die, wie oben erläutert, für eine spätere Feineinstellung der Luftkanalanordnung im Schienenfahrzeug vorteilhaft ist. Ein Ausführungsbeispiel der Erfindung wird nachfolgend unter Bezugnahme auf die Zeichnungen noch näher erläutert. Es zei¬ gen : Figur 1 eine Querschnittsansicht einer Luftverteilbox zum Anschluss an weiterführende Luftkanäle innerhalb eines Schienenfahrzeugs und Schalldämpfeinrichtung which, as explained above, is advantageous for a subsequent fine adjustment of the air duct arrangement in the rail vehicle. An embodiment of the invention will be explained in more detail with reference to the drawings. It zei ¬ gen: 1 shows a cross-sectional view of an air distribution box for connection to further air ducts within a rail vehicle and

Figur 1.  FIG. 1
Wie in Figur 1 veranschaulicht ist, weist eine Luftverteilbox 1 einen Lufteinlass 2 auf, der typischer Weise an ein Klima- gerät eines Schienenfahrzeugs angeschlossen sein wird. Von dem Lufteinlass 2 aus, strömt in das Innere des Schienenfahr¬ zeugs zu transportierende Luft zunächst durch eine Schall¬ dämpfeinrichtung 3, die von im dargestellten Ausführungsbeispiel vier nebeneinander angeordneten, jeweils in einem ge- ringen Winkel zueinander stehenden Strömungsstrecken 4 gebildet ist. Nach Verlassen der Schalldämpfeinrichtung 3 gelangt die einströmende Luft in einen Luftaufteilungsraum 4 innerhalb der Luftverteilbox 1, in dem der von dem Lufteinlass 2 kommende Luftstrom auf zwei Teil-Luftströme aufgeteilt wird, wie es in Figur 1 durch Pfeile veranschaulicht ist. As illustrated in FIG. 1, an air distribution box 1 has an air inlet 2, which will typically be connected to an air conditioning unit of a railway vehicle. From the air inlet 2 of, for transporting air first flows into the interior of the rail vehicle ¬ zeugs by a sound ¬ damping device 3, arranged side by side from the illustrated embodiment, four each in a overall rings angle to each other flow paths 4 are formed. After leaving the Schalldämpfeinrichtung 3 enters the incoming air into an air distribution space 4 within the Luftverteilbox 1, in which the air coming from the air inlet 2 air flow is divided into two partial air streams, as illustrated in Figure 1 by arrows.
Die Luftverteilbox 1 ist mit zwei Luftauslässen 5, 6 ausge¬ stattet, über die die jeweiligen Teil-Luftströme an weiter¬ führende Luftkanäle, die an die Auslässe 5, 6 angeschlossen sind, transportiert wird. The Luftverteilbox 1 is provided with two air outlets 5, 6 ¬ be equipped, on the respective partial air streams is transported to further ¬ leading air channels which are connected to the outlets 5. 6
Dabei ist jedem der Luftauslässe 5, 6 eine als Lochplatte 7, 8 ausgebildete Drosseleinrichtung zugeordnet, wobei die je¬ weilige Lochplatte 7, 8 zwischen dem ihr zugeordneten Luft- auslass 5, 6 und dem Luftaufteilungsraum 4 angeordnet ist. Zwischen den Lochplatten 7, 8 und den zugeordneten Luftauslässen 5, 6 werden die Teil-Luftströme durch Kanalelemente 9, 10 geführt. Die Lochplatten, 7, 8 weisen Druckverlustbeiwerte auf, die derart bemessen sind, dass sich für ein Verhältnis von Luft¬ volumenströmen der beiden Teil-Luftströme an den Luftauslässen 5, 6 ein vorgegebener Wert ergibt. Dabei entspricht das Verhältnis der Druckverlustbeiwerte der Lochplatten 7, 8 dem quadratischen Verhältnis der Strömungsgeschwindigkeiten im Bereich der Luftauslässe 5, 6. Die Lochplatten 7, 8 weisen ein Verhältnis von Plattenstärke zu Lochdurchmesser von größer 1,5 auf, so dass die Lochplat¬ ten 7, 8 zusätzliche Eigenschaften eines Gleichrichters ha¬ ben. ( Idelchik, Handbook of hydaulic resistance, Springer Verlag 1986, Seite 404, Diagramm 8-3) Here, each of the air outlets 5, 6 associated with a perforated plate as 7, 8 designed throttle means, said depending ¬ stays awhile perforated plate 7, 8 between the outlet of its associated air 5, 6 and the air chamber 4 is division. Between the perforated plates 7, 8 and the associated air outlets 5, 6, the partial air streams are passed through channel elements 9, 10. The perforated plates 7, 8 have pressure loss coefficients, which are dimensioned such that there is a predetermined value for a ratio of air ¬ volume flows of the two partial air flows to the air outlets 5. 6 This corresponds to the Ratio of the pressure loss coefficients of the perforated plates 7, 8, the square ratio of the flow rates in the range of the air outlets 5, 6. The perforated plates 7, 8 have a ratio of plate thickness to hole diameter of greater than 1.5, so that the Lochplat ¬ th 7, 8 additional Properties of a rectifier ha ¬ Ben.

Beispielsweise kann eine der Lochplatten 7, 8 30mm dick sein, Löcher mit einem Durchmesser von 20mm aufweisen sowie einen freien Querschnitt von ca. 35%. Eine solche Lochplatte hat einen Druckverlustbeiwert von ca. 7,5. Dieser Wert gewähr- leistet, dass der Druckverlustbeiwert der Lochplatte 7, 8 we¬ nigstens dem Doppelten des Druckverlusts typischer, an die Luftauslässe 5, 6 angeschlossener Luftkanalsysteme von Schie¬ nenfahrzeugen entspräche. Um die beabsichtigte Grobeinstel¬ lung für das Verhältnis der Luftvolumenströme an den Ausläs- sen 5, 6 einzustellen, sind die Druckverlustbeiwerte derFor example, one of the perforated plates 7, 8 be 30mm thick, have holes with a diameter of 20mm and a free cross-section of about 35%. Such a perforated plate has a pressure loss coefficient of about 7.5. This value ensures that the pressure loss coefficient of the orifice plate 7, 8 we ¬ nigstens twice the typical pressure loss at the air outlets 5, 6 attached air channel systems of shift ¬ nenfahrzeugen correspond. To intention Grobeinstel ¬ lung for the ratio of air flow rates to the sen Ausläs- set 5, 6, the pressure drop coefficients are the
Lochplatten 7, 8 entsprechend zu wählen. Beispielsweise be¬ wirken die Druckverlustbeiwerte von 7,5 und 12,0 für die Lochplatten 7,8 in der gezeigten Klimatisierungsanordnung ein Luftvolumenstromverhältnis von 1:1,8. Andere Verhältnisse können durch geeignete Einstellung der Druckverlustbeiwerte der eingesetzten Lochplatten realisiert werden. Perforated plates 7, 8 to choose accordingly. For example, be ¬ the pressure loss coefficients of 7.5 and 12.0 for the perforated plates 7.8 in the illustrated arrangement climate affect an air volume flow ratio of 1: 1.8. Other conditions can be realized by suitable adjustment of the pressure loss coefficients of the perforated plates used.
Die Lochplatten 7, 8 sind im Wesentlichen senkrecht zu den in ihrem Bereich herrschenden Luftströmungen angeordnet, so dass sie einen gewünschten Druckverlust bewirken, bevor die Teil- Luftströme die Luftteilbox an den Luftauslässen 5 und 6 ver¬ lassen . The perforated plates 7, 8 are arranged substantially perpendicular to the prevailing air currents in their area so that they bring about a desired pressure loss before the partial air streams can be the Luftteilbox of the air outlets 5 and 6 ¬ ver.
Die durch die Lochplatten 7, 8 bewirkte Grobeinstellung der Volumenstromverteilung für verschiedene Konfigurationen vonThe coarse adjustment of the volume flow distribution effected by the perforated plates 7, 8 for different configurations of
Schienenfahrzeugwagen an der Luftverteilbox 1, verringert den Einstellaufwand an den einzelnen Wagen (Endwagen, Mittelwagen) , da nur noch eine Feineinstellung vorgenommen werden muss. Effekte der Feineinstellung werden durch die gleichrichtende Wirkung sowohl der Schalldämpfeinrichtung 3 als auch der Lochplatten 7, 8 durch Dämpfung der nichtlinearen Eigenschaften vermindert. Ein positiver Effekt der durch die Lochplatten 7, 8 bewirkten Grobeinstellung der Volumenstromverteilung kann darin bestehen, dass bislang erforderliche Luftleiteinrichtungen, wie Leitbleche und Umlenkungen, ggf. entfallen können. Rail car on the Luftverteilbox 1, reduces the adjustment effort on each car (end car, middle car), since only a fine adjustment can be made got to. Effects of the fine adjustment are reduced by the rectifying effect of both the Schalldämpfeinrichtung 3 and the perforated plates 7, 8 by damping the non-linear properties. A positive effect of the coarse adjustment of the volumetric flow distribution caused by the perforated plates 7, 8 may be that previously required air guiding devices, such as baffles and deflections, may possibly be dispensed with.
