Description

Die Erfindung betrifft ein Unterflurlüftungs-, Heizungs- und/oder Klimagerät mit einem Gehäuse, das unterhalb des Fahrgestells eines Reisezugwagens befestigbar ist, mit Öffnungen zum Ansaugen von Frisch- und Umluft und zum Ausblasen von behandelter Luft.The invention relates to an underfloor ventilation, heating and / or air conditioning device with a Housing that attaches below the chassis of a passenger car is, with openings for sucking in fresh and circulating air and for blowing out treated air.

Bekannte unterflur eingebaute Luftbehandlungsgeräte dieser Art weisen an ihrer Oberseite Öffnungen auf, an die Leitungen angeschlossen sind, die durch den Waggonboden hindurch in den Innenraum des Reisezugwagens geführt sind. Eine Leitung mündet dabei in ein an einer Waggonseitenwand angeordnetes Gehäuse, das einmal mit einer die Seitenwand durchdringenden Öffnung zum Eintritt und Ansaugen von Außenluft und zum anderen mit einer in den Innenraum mündenden Öffnung zum Eintritt und Ansaugen von Umluft versehen ist, wobei zwischen diesen beiden Öffnungen eine Klappe zum Steuern des Mischungsverhältnisses zwischen Außenluft und Umluft bzw. zum Abschluß der Außenluft- oder Umlufteintrittsöffnung vorgesehen ist. Auf der gegenüberliegenden Waggonseite mündet eine zweite mit dem Luftbehandlungsgerät verbundene und den Waggonboden durchsetzende Leitung in ein Gehäuse mit Auslassöffnungen für die behandelte Luft. Die in dem Reisezugwagen angeordneten Gehäuse zum Eintritt und Ansaugen von Außenluft und/oder Umluft und zum Ausblasen von behandelter Luft benötigen relativ viel Raum, so daß im Wagen zwei Sitze entfallen müssen, um das Gehäuse mit der Außenluft- und Umluftansaugung einschließlich Schalldämpfer sowie die Frischluft- und Umluft mischende oder abschließende Klappe unterzubringen.Known underfloor air treatment devices of this type point to their Top openings on to which the lines are connected, which are through the Wagon floor are led into the interior of the passenger car. A The line opens into a housing arranged on a side wall of the wagon, once with an opening penetrating the side wall for entry and suction of outside air and on the other hand with one opening into the interior Opening for the entry and suction of circulating air is provided, between them a valve to control the mixing ratio between the two openings Outside air and recirculating air or to close the outside air or recirculating air inlet opening is provided. A second opens on the opposite side of the wagon connected to the air treatment device and penetrating the wagon floor Line in a housing with outlet openings for the treated air. The one in the Passenger coaches arranged housing for entry and suction of outside air and / or circulating air and for blowing out treated air require a relatively large amount Space, so that two seats in the car have to be omitted to connect the housing with the Outside air and recirculated air intake including silencers as well as fresh air and To house the air-mixing or closing flap.

Grundsätzlich bestünde die Möglichkeit, das Gehäuse zum Eintritt von Außenluft und Umluft mit der Frischluft-Umluftklappe entfallen zu lassen, wenn innerhalb des Wagenbodens ein Querkanal verlegt wird, durch den die Umluft von der der Außenluftansaugung gegenüberliegenden Seite angesaugt wird, und diesem Querkanal dann die Frischluft-Umluftklappe zugeordnet wird. Dieser Querkanal hat aber den Nachteil, daß er Längsträger des Wagenkastens schneidet und daher nur mit ungünstigen Querschnitten bzw. mehrfach geteilt ausgeführt werden kann. Ein weiterer Nachteil besteht in der schlechten Reinigungsmöglichkeit und der Schwierigkeit, Schalldämpfer einzubauen, so daß störende Ventilatorgeräusche und ein unvermeidbarer Druckverlust in diesem Querkanal in Kauf genommen werden müssen.Basically, there is the possibility of the housing for the entry of outside air and to omit recirculation with the fresh air recirculation flap if inside the A cross channel is laid through the car floor, through which the recirculated air from the outside air intake opposite side is sucked, and this cross channel then the fresh air recirculation flap is assigned. But this cross channel has the disadvantage that it cuts the longitudinal members of the car body and therefore only with unfavorable cross sections or divided multiple times. On Another disadvantage is the poor cleaning ability and the difficulty Install silencer so that annoying fan noise and a unavoidable pressure loss in this cross channel can be accepted have to.

Aufgabe der Erfindung ist es daher, ein Unterflurluftbehandlungsgerät zu schaffen, das sich ohne störenden Raumverlust im Innern des Wagens unterflur einbauen läßt, und zwar in einer Weise, daß weder störende Ventilator- und Strömungsgeräusche noch größere Druckverluste in Kauf genommen werden müssen.The object of the invention is therefore to create an underfloor air treatment device, which can be installed under the floor inside the car without any annoying loss of space leaves, in such a way that neither disturbing fan and flow noises even greater pressure losses have to be accepted.

Erfindungsgemäß wird diese Aufgabe bei einem Luftbehandlungsgerät der eingangs angegebenen Art dadurch gelöst, daß das Gehäuse zum Quereinbau unter dem Wagenboden eingerichtet und der Breite des Reisezugwagens angepaßt ist und daß das Gehäuse unter oder im Bereich seiner Deckwand mit mindestens einem Frischluft-/Umluftkanal mit endseitigen Eintrittsöffnungen und einer Klappe- oder Ventilanordnung zum Sperren einer Kanalseite oder zum Mischen von Frisch- und Umluft und mit mindestens einem Kanal für die behandelte Luft versehen ist, der mit mindestens einer Austrittsöffnung versehen ist. According to the invention, this object is achieved at the beginning in an air treatment device specified type solved in that the housing for transverse installation under the floor of the car is set up and the width of the passenger car is adjusted and that the housing under or in the area of its top wall with at least one Fresh air / recirculated air duct with end openings and a flap or Valve arrangement for blocking a channel side or for mixing fresh and Circulating air and is provided with at least one duct for the treated air, which is provided with at least one outlet opening.

Das Gehäuse des erfindungsgemäßen Luftbehandlungsgeräts läßt sich in üblicher Weise einfach unterflur unter dem Fahrgestell des Waggons befestigen. Das Gehäuse ist an der Oberseite im Bereich der Enden mit Öffnungen versehen, die in den längs in diesem und quer zu dem Waggon verlaufenden Frischluft-/Umluftkanal münden. Diese Öffnungen sind mit Leitungen verbunden, von denen eine unmittelbar Frischluft ansaugt oder durch den Waggonboden hindurch zu einer Frischluftansaugöffnung der Seitenwand des Waggons geführt ist. Die gegenüberliegende Öffnung mündet auf der gegenüberliegenden Seite in den Waggon und saugt aus dessen Innern Umluft an. Der bzw. die behandelte Luft führenden Kanäle sind mit mindestens einer Öffnung versehen, an die eine den Waggonboden durchsetzende Leitung angeschlossen ist, so daß durch diese an einer günstigen Stelle behandelte Luft zur Heizung, Lüftung oder Klimatisierung in das Innere des Wagens eingeleitet werden kann. Ventilator- oder Luftströmungsgeräusche treten in störender Weise nicht auf, weil die entsprechenden Aggregate und Leitungen unterflur verlegt sind. Das Gehäuse selbst kann durch schalldämmende Gummielemente mit dem Fahrgestell verbunden werden, so daß auch die Überleitung von Körperschall vermieden wird.The housing of the air treatment device according to the invention can be customary Simply attach it under the floor under the carriage chassis. The housing is provided with openings at the top in the area of the ends, which in the fresh air / recirculated air duct running lengthways in this and across the wagon flow out. These openings are connected to lines, one of which is immediate Fresh air is sucked in or through the wagon floor to a fresh air suction opening the side wall of the wagon is guided. The opposite Opening opens into the wagon on the opposite side and sucks whose interior circulates. The duct (s) carrying the treated air are included Provide at least one opening to which one penetrates the floor of the wagon Line is connected, so that treated by this in a convenient place Air for heating, ventilation or air conditioning is introduced into the interior of the car can be. Fan or air flow noises occur disturbingly not because the corresponding units and lines are installed under the floor. The housing itself can be attached to the chassis using sound-absorbing rubber elements be connected so that the transfer of structure-borne noise is avoided becomes.

Zweckmäßigerweise ist das Gehäuse mit zwei äußeren, behandelte Luft führenden Kanälen und einem mittleren Frischluft-/Umluftkanal versehen, die parallel zueinander verlaufen.Conveniently, the housing with two outer, treated air leading Ducts and a middle fresh air / recirculation duct provided that are parallel to each other run.

Die Wände der Kanäle können zumindest teilweise mit Dämmstoffen belegt sein, die die Bildung von Kondensat verhindern und der Geräuschdämmung, der Wärmeisolation und der Schalldämpfung dienen.The walls of the channels can be at least partially covered with insulation materials, which prevent the formation of condensate and noise insulation, heat insulation and serve the sound absorption.

In weiterer Ausgestaltung der Erfindung ist vorgesehen, daß die Klappenanordnung aus mindestens zwei unabhängig voneinander verschwenkbaren und gegen einander gegenüberliegende Klappensitze anlegbaren Klappen besteht. Diese Klappenanordnung ermöglicht es, entweder durch Verschwenken der Klappen nach einer Seite den Frischluft- oder Umlufteintritt zu sperren oder durch gegensinniges Verschwenken eine Mischung von Frischluft und Umluft zu bewirken. Dadurch sind Zwischenstellungen der Klappen vermieden, die zu einem Flattern der Klappen führen könnten.In a further embodiment of the invention it is provided that the flap arrangement from at least two independently pivotable and against each other Opposing flap seats there are flaps. This flap arrangement allows either by pivoting the flaps after a Side to block the fresh air or recirculated air inlet or by swiveling in opposite directions a mixture of fresh air and recirculated air. Thereby Avoid intermediate positions of the flaps, which cause the flaps to flutter could.

Zweckmäßigerweise besteht die Klappenanordnung aus jeweils mindestens zwei unabhängig voneinander verschwenkbaren, kammartig ineinandergreifenden Klappen, von denen jede auf einer Schwenkwelle befestigte Klappengruppe von einem Antrieb verschwenkbar ist. Von den Schwenkwellen kann eine rohrförmig ausgeführt und die andere in dieser angeordnet sein, wobei die Klappen an der inneren Welle über Bolzen befestigt ist, die die äußere rohrförmige Welle in Umfangsschlitzen durchsetzen.The flap arrangement expediently consists of at least two in each case flaps that can be pivoted independently of one another and interlock with one another, each of which is a group of flaps attached to a swivel shaft Drive is pivotable. One of the swivel shafts can be tubular and the other can be arranged in this, the flaps on the inner Shaft is fastened via bolts that the outer tubular shaft in circumferential slots push through.

Nach einer erfinderischen Weiterbildung ist vorgesehen, daß jeweils mindestens eine Klappe jeder Klappengruppe mit einem Temperaturfühler versehen ist, der das Abheben der Klappe von ihrem Sitz bei plötzlicher Abkühlung oder Temperaturänderung bewirkt. Diese Ausgestaltung verhindert bei plötzlicher Änderung der Außentemperatur, beispielsweise bei Tunnelfahrt, daß unangenehme Temperaturänderungen im Innenraum eintreten. Denn durch das Abheben der Klappe kann beispielsweise eine verstärkte Zumischung von Umluft bewirkt werden.According to an inventive further development, it is provided that in each case at least a flap of each flap group is provided with a temperature sensor which Lift the flap off its seat in the event of sudden cooling or a change in temperature causes. In the event of a sudden change in the outside temperature, this configuration prevents for example when driving through a tunnel, that unpleasant temperature changes enter inside. Because by lifting the flap, for example an increased admixture of circulating air can be effected.

Nach einer bevorzugten Ausführungsform ist vorgesehen, daß mindestens eine Klappe jeder Klappengruppe mit einem Bimetallstreifen in der Weise belegt oder verbunden ist, daß sie sich bei Abkühlung von ihrem Sitz abhebt. Durch diese Ausgestaltung wird vorrichtungsmäßig das Öffnen einer Klappe bei plötzlicher Abkühlung bewirkt, ohne daß ein besonderer Steuerungsablauf eingeleitet werden müßte. Das Abheben der mit Bimetall versehenen Klappen wird dadurch ermöglicht, daß sich mindestens eine keinen Bimetallstreifen aufweisende Klappe jeder Klappenwelle auf ihrem Sitz abstützt, da der Stellmotor das Stützmoment aufrechterhält.According to a preferred embodiment it is provided that at least one Flap of each flap group covered with a bimetallic strip or is connected that it stands out from its seat when it cools down. Through this configuration the device opens a flap in the event of sudden cooling effected without a special control process having to be initiated. The lifting of the bimetallic flaps is made possible by the fact that at least one flap with no bimetal strip on each flap shaft supported on their seat, since the servomotor maintains the support torque.

Nach einer anderen Ausführungsform ist vorgesehen, daß mindestens eine Klappe mit einem fensterartigen Durchbruch versehen ist, der durch eine Bimetallklappe oder eine von einem Bimetall verschwenkbare Klappe verschließbar ist. Auch diese Ausgestaltung ermöglicht eine schnelle Reaktion auf plötzliche Änderungen der Außentemperatur.According to another embodiment it is provided that at least one flap is provided with a window-like opening through a bimetallic valve or a flap that can be pivoted by a bimetal can be closed. This too Design allows a quick reaction to sudden changes in the Outside temperature.

Zweckmäßigerweise ist ein Sensor vorgesehen, der die Relativbewegung der Klappe zu dem Sitz oder der benachbarten Platte mißt. Aufgrund des Signals dieses Sensors können die Klappen entsprechend der Änderung der Außentemperatur durch vorhandene Steuereinrichtungen verstellt werden.A sensor is expediently provided, which detects the relative movement of the flap to the seat or the adjacent plate. Because of the signal this Sensor can flaps according to the change in outside temperature can be adjusted by existing control devices.

Das Gehäuse ist zweckmäßigerweise mit der Wartung dienenden verschließbaren Öffnungen versehen, so daß ein einfacher und schneller Zugang zu den einzelnen Komponenten möglich ist, ohne daß in umständlicher Weise Verkleidungen oder Wandteile des Waggons entfernt werden müßten.The housing is expediently closable with the maintenance serving Provide openings so that easy and quick access to each Components is possible without cladding or cumbersome Wall parts of the wagon would have to be removed.

Das erfindungsgemäße Luftbehandlungsgerät ermöglicht eine Wartung und einen Austausch sämtlicher Komponenten des Aggregats durch stirnseitig vorgesehene Klappen. Eine einfache Wartung der Frischluft-Umluftklappe sowie des Kanalsystems ist durch Abhängen von Verschlußdeckeln möglich. Die Geräuschdämmung in den Luft führenden Kanälen kann einfach durch schalldämmende Elemente bewirkt werden. Die Ansaugöffnung für Umluft sowie die Ausblasöffnungen für behandelte Luft lassen sich variabel und platzsparend im gesamten Innenbereich des Wagens anordnen.The air treatment device according to the invention enables maintenance and maintenance Replacement of all components of the unit with those provided on the front Valves.
