Ferner betrifft die vorliegende Erfindung ein Regional trains, wherein the rail vehicle has a system for the air conditioning of the at least one driver's compartment. Furthermore, the present invention relates to a
Verfahren zur Erzeugung eines Überdrucks im Maschinenraum in Verbindung mit einer Klimatisierung mindestens eines Führerraumes. Method for generating an overpressure in the engine room in conjunction with air conditioning of at least one driver's compartment.
Der Maschinenraum derartiger Fahrzeuge dient zur Aufnahme von elektrischen The engine room of such vehicles is used to hold electrical
Vorrichtungen, die insbesondere für den Betrieb des Schienenfahrzeuges notwendig sind, beispielsweise von elektrischen Komponenten, die für die Energieversorgung eines elektrischen Traktionsantriebes vorgesehen sind, sowie von Hilfsbetrieben, die nicht unmittelbar für den Antrieb des Fahrzeuges dienen, beispielsweise einer Druckluft- Erzeugungsvorrichtung. Die genannten elektrischen und anderen Vorrichtungen sind empfindlich gegen Verschmutzungen. Daher soll der Maschinenraum so staubfrei wie möglich gehalten werden. Andernfalls ist deren Lebensdauer begrenzt, und ihre Devices that are necessary in particular for the operation of the rail vehicle, for example, of electrical components that are provided for the power supply of an electric traction drive, as well as auxiliary operations that do not directly for the drive of the vehicle, such as a compressed air generating device. The said electrical and other devices are sensitive to contamination. Therefore, the engine room should be kept as dust-free as possible. Otherwise, their life is limited, and their
Ausfallrate steigt an. Failure rate increases.
Um diese Aufgabe zu erfüllen, ist beispielsweise in EP 2 127 991 A1 eine Lokomotive beschrieben, die zwei Führerstände und einen Maschinenraum aufweist, wobei zur Kühlung des Maschinenraumes und wenigstens eines Führerstandes wenigstens ein Kühlaggregat und ein kanalförmiges Leitungssystem zum Führen eines vom Kühlaggregat gekühlten Luftstromes vorgesehen sind. Das Leitungssystem ermöglicht die Führung der gekühlten Luft durch Öffnungen, derart dass die gekühlte Luft gezielt auf die zu kühlenden Komponenten auftrifft, oder bis in Schränke mit zu kühlenden Komponenten hineingeleitet wird. In einem Ausführungsbeispiel verfügt die Lokomotive über zwei Führerstände, die je nach Fahrtrichtung unbesetzt oder besetzt sind. In jedem der beiden Führerstände ist in einer ersten Ausführungsform ein Klimagerät angeordnet. Das Klimagerät des unbesetzten Führerstandes wird zum Kühlen des Maschinenraumes vorgesehen, während zur gleichen Zeit das Klimagerät des besetzten Führerstandes ausschließlich zum Klimatisieren dieses Führerstandes verwendet wird. In einer zweiten In order to achieve this object, a locomotive is described for example in EP 2 127 991 A1, which has two driver's cabs and a machine room, wherein for cooling the machine room and at least one driver's cab at least one cooling unit and a channel-shaped line system for guiding an air stream cooled by the cooling unit are. The conduit system allows the guidance of the cooled air through openings so that the cooled air hits the components to be cooled in a targeted manner or is directed into cabinets with components to be cooled. In one embodiment, the locomotive has two driver's cabs, which are unoccupied or occupied depending on the direction of travel. In each of the two driver's cabs, an air conditioner is arranged in a first embodiment. The air conditioner of the Unoccupied cab is provided for cooling the engine room, while at the same time the air conditioner of the occupied cab is used exclusively for air conditioning this cab. In a second
Ausführungsform befindet sich ein zentrales Klimagerät im Maschinenraum. Gekühlte Luft wird in diesem Falle in ein sich T-förmig durch den Maschinenraum bis in die beiden Führerstände erstreckendes Leitungssystem eingeleitet und über dieses Leitungssystem bis in den besetzten Führerstand geführt, während das Leitungssystem am unbesetzten Führerstand verschlossen bleibt, sodass dort keine gekühlte Luft eintreten kann. In JP 10-129476 A ist ein Klimagerät für Schienenfahrzeuge mit einem Innengebläse angegeben, das unter dem Boden des Fahrzeuges befestigt ist. Das Klimagerät umfasst ein erstes Gebläse für die Belüftung und den Ausstoß von Luft, ferner zwei Verdampfer und ein zweites Innengebläse. Die mit dem ersten Gebläse angesaugte Luft wird von dem ersten Verdampfer abgekühlt. Die abgekühlte Luft wird mit Luft aus dem Innenraum des Fahrzeuges vermischt, und das resultierende Gemisch wird in einem weiteren Embodiment is a central air conditioner in the engine room. Cooled air is introduced in this case in a T-shaped extending through the engine room to the two driver's cabs line system and guided over this line system to the occupied driver's cab, while the line system remains closed at the unoccupied cab, so there can be no cooled air , JP 10-129476 A discloses an air conditioner for railway vehicles with an internal fan which is fixed under the floor of the vehicle. The air conditioner includes a first fan for the ventilation and the discharge of air, two evaporators and a second internal fan. The air sucked in with the first blower is cooled by the first evaporator. The cooled air is mixed with air from the interior of the vehicle, and the resulting mixture is in another
Verdampfer abgekühlt. Mit dem zweiten Innengebläse wird die gekühlte Luft in den Innenraum des Fahrzeuges geblasen.  Evaporator cooled. With the second internal fan, the cooled air is blown into the interior of the vehicle.
Mit den bekannten Klimatisierungssystemen ist es zwar möglich, einen Innenraum eines Fahrzeuges auf eine ausreichend niedrige Temperatur abzukühlen. EP 2 217 991 A1 gibt hierzu an, dass die Kühlung der elektrischen und elektronischen Komponenten erforderlich ist, um die Ausfallrate dieser Komponenten zu verringern. Hierzu wird die gekühlte Luft in dem dort beschriebenen Schienenfahrzeug gezielt auf die Komponenten gerichtet. Allerdings hat es sich herausgestellt, dass die Ausfallrate trotzdem nicht in ausreichendem Umfange gesenkt werden kann. Ferner ist zu berücksichtigen, dass die Kosten der Herstellung eines Schienenfahrzeuges hoch sein können, wenn wie in der einen in EP 2 217 991 A1 angegebenen Ausführungsform mehrere Klimageräte verwendet werden. Dieses Problem wird gelöst durch das Schienenfahrzeug mit einem Maschinenraum sowie mit mindestens einem Führerraum gemäß Patentanspruch 1 und dem Verfahren zur Erzeugung eines Überdrucks im Maschinenraum in Verbindung mit einer With the known air conditioning systems, it is indeed possible to cool an interior of a vehicle to a sufficiently low temperature. For this purpose, EP 2 217 991 A1 states that the cooling of the electrical and electronic components is required in order to reduce the failure rate of these components. For this purpose, the cooled air is specifically directed to the components in the rail vehicle described therein. However, it has been found that the failure rate can still not be reduced to a sufficient extent. Furthermore, it should be considered that the cost of manufacturing a rail vehicle can be high if, as in one embodiment specified in EP 2 217 991 A1, several air conditioning units are used. This problem is solved by the rail vehicle with a machine room and with at least one driver's compartment according to claim 1 and the method for generating an overpressure in the engine room in conjunction with a

Subclaims specified. The rail vehicle according to the invention has a machine room and at least one driver's compartment.

Mit der Erfindung wird erreicht, dass die mittels des Klimatisierungssystems in mindestens einen Führerraum eingeleitete und gegebenenfalls bereits gefilterte und/oder gekühlte Luft zumindest teilweise in den Maschinenraum weiter geleitet wird, sodass sich im Maschinenraum ein gegenüber der Umgebung erhöhter Luftdruck einstellt. Dadurch wird erreicht, dass die in den Maschinenraum eingeleitete Luft wesentlich weniger mit With the invention it is achieved that the introduced by means of the air conditioning system in at least one driver's compartment and possibly already filtered and / or cooled air is at least partially passed into the engine room, so that sets in the engine room a relation to the environment increased air pressure. This ensures that the introduced into the engine room air much less

Maschinenraum eintretende Frischluft, sodass die Ausfallsicherheit von sich im Engine room entering fresh air, so the reliability in itself

Da es für den Betrieb des Maschinenraumes im Fahrzeug ausreicht, eine relativ kleine Luftmenge über den mindestens einen Führerraum einzuleiten, wird der Eintrag von Verunreinigungen und/oder Feuchtigkeit in den Moisture increases. Since it is sufficient for the operation of the engine room in the vehicle to initiate a relatively small amount of air through the at least one cab, the entry of impurities and / or moisture in the
Maschinenraum minimiert. Jedenfalls wird bevorzugt nur so viel Luft von dem mindestens einen Führerraum in den Maschinenraum weitergeleitet, wie gerade für das Engine room minimized. In any case, only so much air is preferred from the at least forwarded a cab to the engine room, just like that

Durch das Weiterleiten der in den mindestens einen Führerraum eingeleiteten Frischluft in den Maschinenraum wird auch erreicht, dass gegebenenfalls in der Frischluft enthaltene Verunreinigungen bereits in dem mindestens einen Führerraum dadurch zurückgehalten werden, dass sich diese dort absetzen. Das Weiterleiten der in den mindestens einen Führerraum eingeleiteten Frischluft in den Maschinenraum reicht ferner aus, um im Maschinenraum einen gegenüber der Umgebung erhöhten Innenluftdruck (insbesondere einen leichten Maintenance of a slight overpressure is required so that the reliability of the components in the engine room is not compromised. By passing the fresh air introduced into the at least one driver's compartment into the machine room, it is also achieved that any impurities contained in the fresh air are already held back in the at least one driver's compartment by settling there. The forwarding of the fresh air introduced into the at least one driver's compartment into the machine room is furthermore sufficient to produce an increased internal air pressure in the engine room (in particular a light one)
Überdruck) aufrechtzuerhalten. Mit dem erhöhten Luftdruck wird gewährleistet, dass Verunreinigungen und/oder Feuchtigkeit auch dann nicht von außen in den Overpressure). With the increased air pressure, it is ensured that impurities and / or moisture can not be absorbed from outside
Maschinenraum eindringen können, wenn der Maschinenraum gegenüber der Umgebung nicht vollständig abgedichtet ist, da ein Eindringen der Verunreinigungen und/oder von Feuchtigkeit durch den Überdruck verhindert wird. Engine room can penetrate, if the engine room is not completely sealed from the environment, since penetration of impurities and / or moisture is prevented by the overpressure.
Nicht zufrieden stellend für eine Optimierung der Ausfallsicherheit der elektrischen und anderen Komponenten hat sich dagegen herausgestellt, wenn Luft von einem Not satisfactory for optimizing the reliability of the electrical and other components, however, has turned out to be when air from one
Fahrmotorlüfter abgezweigt wird, um den Überdruck im Maschinenraum zu erzeugen, da damit zusätzliche Verunreinigungen und Feuchtigkeit in den Maschinenraum eingebracht würden. Auch die Installation von separaten Maschinenraumlüftern, die Frischluft ansaugen, hat sich als nachteilig erwiesen. Eine dauerhafte Maschinenraumfilterung, die Staub aller Feinheitsgrade und Feuchtigkeit zuverlässig zurückhält, ist mit diesen Traction motor fan is branched off to generate the pressure in the engine room, as this would be introduced additional impurities and moisture in the engine room. The installation of separate engine room fans, which suck in fresh air, has proven to be disadvantageous. A permanent machine room filtration, which reliably retains dust of all degrees of fineness and humidity, is with them

Erfindungsgemäß wird diese Frischluft nicht Undefiniert abgeleitet, sondern nach dem Einleiten in den Führerraum in den Maschinenraum weitergeleitet. Das Klimatisierungssystem umfasst beispielsweise mindestens ein Kühlelement und kann von daher in der Lage sein, den mindestens einen Führerraum zu kühlen. Ferner können von dem Klimatisierungssystem auch Filterelemente, Führungselemente für die Luft, beispielsweise Führungskanäle, Rohre und dergleichen, Schaltmittel zum Absperren des Durchtrittes von Luft durch die Führungselemente und dergleichen umfasst sein. Ein Kühlelement kann sich an einer beliebigen, technisch bevorzugten Stelle im oder am Fahrzeug befinden. Mehrere Kühlelemente können an unterschiedlichen Stellen im oder am Fahrzeug angeordnet sein. Procedure not possible. In any case, air is introduced into the at least one driver's compartment in order to supply the person present there with fresh air. According to the invention, this fresh air is not discharged undefined, but forwarded after being introduced into the cab in the engine room. The air conditioning system includes, for example, at least one cooling element and therefore may be able to cool the at least one cab compartment. Furthermore, filter elements, guide elements for the air, for example guide channels, pipes and the like, switching means for shutting off the passage of air through the guide elements and the like may also be included in the air conditioning system. A cooling element may be at any, technically preferred location in or on Vehicle are located. Several cooling elements can be arranged at different locations in or on the vehicle.

Die Kühlung wird durch mindestens ein In a preferred embodiment of the invention, when introducing the fresh air into the at least one driver's compartment, the air-conditioning system comprises a cooling of the fresh air in order to produce cooled air. The cooling is done by at least one

Grundsätzlich sind hier einsetzbare Filtervorrichtungen auf dem Gebiet der Erfindung bekannt und durch entsprechende Halterungen und darin befestigte, beispielsweise aus Vliesen bestehende oder andere gasdurchlässige Engine room filter device. In principle, filter devices which can be used here are known in the field of the invention and are fastened by corresponding holders and, for example, nonwovens or other gas-permeable ones fastened therein
Materialien gebildet. Mit diesen Mitteln wird erreicht, dass die in den mindestens einen Maschinenraum eingeleitete Luft zumindest weitgehend frei von Verunreinigungen und/oder Feuchtigkeit ist. In noch einer weiter bevorzugten Ausführungsform der Erfindung umfasst das  Materials made. By means of this it is achieved that the air introduced into the at least one engine room is at least largely free of contaminants and / or moisture. In yet a further preferred embodiment of the invention, the

Auch derartige Vorrichtungen sind auf dem Gebiet der Erfindung bekannt und werden in der Klimatechnik verwendet. Durch Verwendung mindestens einer Maschinenraumluftfördervorrichtung kann die Förderung der gekühlten Luft in den Maschinenraum abhängig von der Förderung der Frischluft in den mindestens einen Führerraum ausgebildet werden. Der Luftdruck in dem mindestens einen Führerraum unterscheidet sich von dem Luftdruck im Maschinenraum, dadurch dass im for example, comprising at least one engine room fan / at least one engine room blower, for forwarding the fresh air portion of the cab air in the engine room. Also such devices are known in the art and are used in the air conditioning industry. By using at least one engine room air conveying device, the delivery of the cooled air into the engine room can be formed as a function of the delivery of fresh air into the at least one driver's compartment. The air pressure in the at least one driver's compartment differs from the air pressure in the engine room, in that in the
Maschinenraum ein Überdruck hergestellt und gleichzeitig etwa Normaldruck Engine room produced an overpressure and at the same time about normal pressure
(entsprechend dem Luftdruck au ßerhalb des Schienenfahrzeuges) in dem mindestens einen Führerraum eingehalten wird. Somit kann der mindestens eine Führerraum ständig mit Frischluft versorgt werden, während dies für den Maschinenraum vermieden und im Maschinenraum ein gegenüber dem außerhalb des Fahrzeuges herrschenden Luftdruck erhöhter Luftdruck eingestellt wird. Dadurch wird erreicht, dass Frischluft auch durch Undichtigkeiten in den Außenwänden des Maschinenraumes nicht nach innen dringt und dabei Verunreinigungen und/oder Feuchtigkeit mit sich führt, sondern vielmehr allenfalls Luft durch Undichtigkeiten und andere Öffnungen aus dem Maschinenraum nach außen dringen kann. (According to the air pressure au ßerhalb the rail vehicle) in the at least one driver's compartment is maintained. Thus, the at least one driver's compartment can be constantly supplied with fresh air, while this is avoided for the engine room and in the engine room a relative to the pressure prevailing outside of the vehicle air pressure increased air pressure is set. This ensures that fresh air is also through Leaks in the outer walls of the engine room does not penetrate to the inside, thereby carrying impurities and / or moisture with it, but at best air can leak through leaks and other openings from the engine room to the outside.
Die Maschinenraumluftfördervorrichtung und die Maschinenraumfiltervorrichtung können in einer Maschinenraumluftbehandlungsvorrichtung zusammengefasst sein. Die The engine room air delivery device and the engine room filter device may be combined in an engine room air treatment device. The

Railway vehicle or under the vehicle or in the engine room of the vehicle or preferably housed in the region of the partition wall between at least one driver's compartment and the engine room.
Somit hat sich insbesondere gezeigt, dass die Sauberkeit der in den Maschinenraum geförderten Luft vor allem von der Güte der Filterung abhängig ist. Mindestens eine Maschinenraumfiltervorrichtung kann entweder auf der Saugseite oder auf der Druckseite des oder der Maschinenraumlüfter oder -gebläse oder sowohl auf deren Saugseite als auch auf deren Druckseite angeordnet sein. Thus, it has been shown, in particular, that the cleanliness of the air conveyed into the engine room depends above all on the quality of the filtration. At least one engine room filter device may be arranged either on the suction side or on the pressure side of the engine room fan or blower or both on the suction side and on the pressure side thereof.
In noch einer weiter bevorzugten Ausführungsform der Erfindung ist der Maschinenraum im Wesentlichen dicht ausgebildet, sodass sich beim Weiterleiten von Luft in den In yet a further preferred embodiment of the invention, the engine room is substantially dense, so that when passing air into the

This filtering includes at least one
Führerraumfiltervorrichtung. Auch derartige Filtervorrichtungen sind auf dem Gebiet der Erfindung bekannt. Durch die zusätzliche Filterung der Frischluft beim Eintritt in den mindestens einen Führerraum wird eine besonders saubere und trockene Luft erzeugt, sodass sich die Probleme der bekannten Klimatisierungssysteme für Schienenfahrzeuge leicht lösen lassen. Das Klimatisierungssystem kann weiterhin jeweils eine Cab filter device. Such filter devices are also known in the art. The additional filtering of the fresh air when entering the at least one driver's compartment produces a particularly clean and dry air, so that the problems of the known air conditioning systems for rail vehicles can be easily solved.

Diese Schließvorrichtung dient insbesondere zur Aufrechterhaltung eines ausreichenden Überdruckes im  Air conditioning system further comprises at least one closing device, which prevents a back flow of the forwarded into the engine room air in the at least one driver's compartment. This may be a non-return valve, but of course also any other suitable device, for example, a valve that closes automatically or by external control as soon as air from the engine room wants to escape back into the driver's compartment. This locking device is used in particular for maintaining a sufficient overpressure in

Insbesondere dient diese Schließvorrichtung dazu, den einmal erreichten Überdruck auch dann aufrechtzuerhalten, wenn sich der Überdruck aufgrund einer Fehlfunktion, beispielsweise beim Ausfallen mindestens einer der Engine room, without a constantly increased inflow of air is required in the engine room. In particular, this locking device is used to maintain the pressure once reached even if the pressure due to a malfunction, for example, when at least one of the failures

Klimatisierungssystem ferner eine Umwälzung eines ersten Teils der in den mindestens einen Führerraum eingeleiteten Frischluft sowie ein Einblasen eines zweiten Teils der Frischluft in den Maschinenraum. Hierzu verzweigt sich ein sich im Führerraum ausbildender Strom von Luft in den ersten und den zweiten Teil, wobei der erste Teil wieder in den Führerraum eingeleitet wird (umgewälzt wird) und der zweite Teil in den Maschinenraum weitergeleitet wird. Durch die entsprechende Ansteuerung der Lüfter kann sichergestellt werden, dass immer nur so viel Luft in den Maschinenraum gefördert wird, wie als Frischluft dem Führerraum zugeführt wird, um einen Unterdruck im Air conditioning system further comprises a circulation of a first part of the fresh air introduced into the at least one driver's compartment as well as an injection of a second part of the fresh air into the engine room. For this purpose, a stream of air which forms in the driver's compartment branches into the first and the second part, the first part being reintroduced into the driver's compartment (being circulated) and the second part being forwarded into the engine room. By appropriate control of the fan can be ensured that only as much air is conveyed into the engine room, as fresh air is supplied to the cab to a negative pressure in

In noch einer weiter bevorzugten Ausführungsform der Erfindung umfasst das To avoid the driver's compartment. Thus, the ingress of contaminants and / or moisture in the at least one driver's compartment and thus also their penetration into the engine room is minimized. In yet a further preferred embodiment of the invention, the
Klimatisierungssystem ferner eine Kühlung des ersten Teils der umgewälzten Frischluft. Damit wird eine fortwährende Kühlung der in dem mindestens einen Führerraum umgewälzten Frischluft erreicht. Zur Kühlung kann wiederum mindestens ein Kühlelement eingesetzt werden, beispielsweise ein oder mehrere Verdampfer einer Kältemaschine oder thermoelektrische Kühlelemente oder noch andere Kühlelemente.

This filtering comprises at least one recirculation filter device. Continuous filtering of the recirculated air further reduces their degree of contamination and / or their moisture, so that even into the engine room
weitergeleitete Luft noch sauberer und/oder trockener wird als ohne diese Maßnahme. Die Umwälzfilterung kann mit der Führerraumfilterung der in den mindestens einen Führerraum eingeleiteten Frischluft identisch sein, sodass die Frischluft und die aus dem Führerraum stammende und umgewälzte Luft durch dieselbe Führerraumfiltervorrichtung geführt werden. Alternativ können aber auch zwei verschiedene Filtervorrichtungen vorgesehen sein, nämlich eine Umwälzfiltervorrichtung für die Filterung des Anteils der umgewälzten Luft und eine Führerraumfiltervorrichtung für die Filterung der dem redirected air becomes even cleaner and / or drier than without this measure. The recirculation filtration may be identical to the cab filtration of the fresh air introduced into the at least one cab so that the fresh air and the air coming from the cab and circulated through the cab are routed through the same cab filter device. Alternatively, however, two different filter devices may be provided, namely a Umwälzfiltervorrichtung for filtering the proportion of circulating air and a cab filter device for filtering the

Verdampfer zur Kühlung der Frischluft dient. Ein derartiger Verdampfer ist ein Evaporator for cooling the fresh air is used. Such an evaporator is a
Kühlelement für die zu kühlende Luft. Kältemaschinen sind bekannt und umfassen typischerweise mindestens einen Verdampfer, mindestens einen Verdichter, mindestens einen Kondensator und mindestens ein Expansionsventil in mindestens einem Kreislauf für ein Kältemittel. Der mindestens eine Verdampfer dient zur Wärmeaufnahme aus der Umgebung in das Kältemittel. Unter anderem die aufgenommene Wärmemenge wird vom Kältemittel in dem mindestens einen Kondensator wieder abgegeben. Somit dient der mindestens eine Verdampfer als Wärmesenke und damit als Kühlelement für die Cooling element for the air to be cooled. Chillers are known and typically include at least one evaporator, at least one compressor, at least one condenser and at least one expansion valve in at least one circuit for a refrigerant. The at least one evaporator is used to absorb heat from the environment in the refrigerant. Among other things, the absorbed amount of heat is released from the refrigerant in the at least one capacitor again. Thus serves the at least one evaporator as a heat sink and thus as a cooling element for the

Bei Verwendung einer Kältemaschine bei dem erfindungsgemäßen Schienenfahrzeug wird der mindestens eine Verdampfer vorzugsweise in eine Führerraumluftbehandlungs- vorrichtung integriert, um dort als Kühlelement für die zu kühlende Frischluft zu wirken. Mindestens ein Kühlelement, ferner vorzugsweise mindestens ein Lüfter oder Gebläse und ferner bevorzugt eine Filtervorrichtung können in der Führerraumluftbehandlungs- vorrichtung zusammengefasst sein. Somit umfasst die mindestens eine Kältemaschine jeweils mindestens einen Verdampfer zur Kühlung der Luft, wobei der mindestens eine Verdampfer vorzugsweise jeweils Bestandteil einer Führerraumluftbehandlungs- vorrichtung des Klimatisierungssystems ist, in der die gekühlte Luft erzeugt wird. When using a refrigerating machine in the rail vehicle according to the invention, the at least one evaporator is preferably integrated into a cab air treatment device in order to act there as a cooling element for the fresh air to be cooled. At least one cooling element, furthermore preferably at least one fan or blower, and furthermore preferably a filter device can be combined in the driver's compartment air treatment device. Thus, the at least one refrigerating machine in each case comprises at least one evaporator for cooling the air, wherein the at least one evaporator is preferably in each case part of a cab air treatment device of the air conditioning system, in which the cooled air is generated.

In an installation of the evaporator (s) behind the cab filter apparatus, extra clean filtered air may be passed through the evaporator (s), thereby reducing the risk of contamination of the evaporator (s).
Die mindestens eine Führerraumluftbehandlungsvorrichtung kann insbesondere innerhalb zumindest eines der Führerräume angeordnet sein. Alternativ kann sie auch au ßerhalb der Führerräume, insbesondere außerhalb des Schienenfahrzeuges, beispielsweise auf dem Dach oder - weniger bevorzugt - unter dem Boden des Schienenfahrzeuges angebracht sein. Bevorzugt ist selbstverständlich eine Anordnung im Führerraum, da damit eine Kapselung gegen von au ßen eindringende Wärme und Verunreinigungen verbunden ist. Darüber hinaus muss für diese Vorrichtung kein zusätzlicher Raum innerhalb des von einem Bahnbetreiber vorgegebenen Fahrzeugprofils beansprucht werden. The at least one driver's compartment air treatment device can in particular be arranged within at least one of the driver's cabs. Alternatively, it may also be outside the driver's cab, in particular outside the rail vehicle, for example, on the roof or - less preferably - be mounted under the floor of the rail vehicle. Of course, preference is given to an arrangement in the driver's cab, since so that an encapsulation is connected against external Shen penetrating heat and impurities. In addition, no additional space within the specified by a railway operator vehicle profile needs to be claimed for this device.

On the graphic representation of itself in the engine room 2 located electrical devices, such as electronic devices with electronic and / or
mikroelektronischen Vorrichtungen zur Steuerung des Betriebes des Fahrzeuges, ist zum Zwecke der klareren Darstellung der Erfindung verzichtet worden. microelectronic devices for controlling the operation of the vehicle has been omitted for purposes of clarity of the invention.
Auf dem Dach des Schienenfahrzeuges ist im Bereich des Führerraumes 1 ein Klimagerät 3 installiert. Das Klimagerät 3 könnte auch unter dem Boden des Fahrzeuges oder alternativ - und durchaus ebenfalls bevorzugt - innerhalb des Führerraumes 1 angeordnet sein. On the roof of the rail vehicle, an air conditioner 3 is installed in the area of the driver's compartment 1. The air conditioner 3 could also be under the floor of the vehicle or alternatively - and quite likewise preferably - be arranged within the driver's compartment 1.
Das Klimagerät 3 umfasst eine Führerraumluftbehandlungsvorrichtung 8, die im vorliegenden Fall zwei Führerraumlüfter 9 sowie einen Verdampfer 4 enthält. Außerdem ist in der Führerraumluftbehandlungsvorrichtung 8 eine Führerraumfiltervorrichtung angeordnet (nicht gezeigt) und zwar in Strömungsrichtung der eingesaugten Frischluft gesehen hinter den Führerraumlüftern 9 und vor dem Verdampfer 4. Die zu dem The air conditioner 3 comprises a cab air treatment device 8, which in the present case contains two cab ventilators 9 and an evaporator 4. In addition, in the cab air treatment apparatus 8, a cab filter apparatus (not shown) is arranged, viewed in the flow direction of the sucked fresh air, behind the cab ventilators 9 and in front of the evaporator 4

Expansionsventil, einer Kältemaschine können ebenfalls im Klimagerät 3 oder an anderer Stelle im Schienenfahrzeug untergebracht sein. Expansion valve, a chiller can also be housed in the air conditioner 3 or elsewhere in the rail vehicle.
Weiterhin befindet sich im Klimagerät 3 eine Maschinenraumluftbehandlungsvorrichtung 1 1 , in der ein Masch inenraumlüfter 6 und eine Maschinenraumfiltervorrichtung Furthermore, located in the air conditioner 3, a machine room air treatment device 1 1, in which a Masch inenraumlüfter 6 and an engine room filter device
(Umluftfilter) 5 zusammengefasst sind. (Recirculation filter) 5 are summarized.
Zwischen der Führerraumluftbehandlungsvorrichtung 8 und der Maschinenraumluft- behandlungsvorrichtung 1 1 befinden sich im Klimagerät 3 Luftführungen 13 (nur schematisch gezeigt) für aus dem Führerraum 1 einströmende, bereits gekühlte Luft, die einen ersten Teil der Luft in die Führerraumluftbehandlungsvorrichtung 8 und einen zweiten Teil der Luft in die Maschinenraumluftbehandlungsvorrichtung 1 1 befördern. Between the cab air treatment device 8 and the engine room air treatment device 1 1, there are air ducts 13 in the air conditioner 3 (shown only schematically) for already cooled air flowing in from the cab compartment 1, containing a first part of the air into the cab air treatment device 8 and a second part of the air into the engine room air treatment device 1 1.
Zur Weiterleitung der gekühlten Luft in den Maschinenraum 2 dient ein Luftkanal 12. In der den Führerraum 1 vom Maschinenraum 2 trennenden Wand 10 bzw. in den Luftkanal 12 ist ferner eine Rückschlagklappe 7 eingebaut. For the forwarding of the cooled air in the engine room 2, an air channel 12 is used in the driver's compartment 1 from the engine room 2 separating wall 10 and in the air channel 12, a check valve 7 is also installed.
Von au ßen kommende Frischluft tritt in einer vorgegebenen Mindestmenge über das Dach des Schienenfahrzeuges in die Führerraumluftbehandlungsvorrichtung 8 ein (erste Luftführung, dargestellt durch Pfeile 21 ). Die Luft wird über die Führerraumlüfter 9 angesaugt und wird anschließend durch den Verdampfer 4 abgekühlt. Außerdem wird die Luft auch durch eine sich in der Führerraumluftbehandlungsvorrichtung 8 befindende Führerraumfiltervorrichtung geleitet, um eine Reinigung der Luft zu erreichen (nicht gezeigt). Nach der Reinigung und anschließenden Abkühlung der Luft im Verdampfer 4 auf eine vorgegebene Temperatur tritt die Luft nach unten aus der Führerraumluft- behandlungsvorrichtung 8 aus und in den Führerraum 1 ein (dargestellt durch Pfeile 22). Die in den Führerraum 1 eingeleitete gekühlte Luft wird vom Klimagerät 3 wieder angesaugt und verzweigt sich in der zweiten Luftführung 13. Ein erster Teil der Luft wird durch die Führerraumlüfter 9 erneut in die Führerraumluftbehandlungsvorrichtung 8 gesaugt und dort nochmals gekühlt (dargestellt durch Pfeil 23). Dies führt zu einer kühlenden Umwälzung der Luft im Führerraum 1 . Die aus dem Verdampfer 4 nach unten in den Führerraum 1 austretende gekühlte Luft enthält somit Anteile der Frischluft sowie Anteile der umgewälzten Luft (dargestellt durch Pfeile 22). Ein zweiter Teil der Luft, ungefähr entsprechend der Menge der ständig zugeführten Frischluft, wird durch den Maschinenraumlüfter 6 in die Maschinenraumluftbehandlungsvorrichtung 1 1 gesaugt, wobei die angesaugte Luft zunächst durch die Maschinenraumfilterung 5 geführt wird (dargestellt durch Pfeil 24). Die gereinigte Luft gelangt dann durch den Luftkanal 12 und die Rückschlagklappe 7 in den weitgehend dichten Maschinenraum 2 (dargestellt durch Pfeil 25). Durch den Maschinenraumlüfter 6 wird fortwährend Luft in den Maschinenraum 2 eingeleitet. Dies führt zu einem gegenüber der Umgebung erhöhten Luftdruck imFresh air coming from outside enters the driver's cabin air treatment device 8 in a predetermined minimum amount via the roof of the rail vehicle (first air duct, represented by arrows 21). The air is sucked in via the cab ventilator 9 and is then cooled by the evaporator 4. In addition, the air is also passed through a cab space filter device located in the cab air-handling device 8 to achieve cleaning of the air (not shown). After cleaning and subsequent cooling of the air in the evaporator 4 to a predetermined temperature, the air exits downwards from the cab air treatment device 8 and into the driver's compartment 1 (shown by arrows 22). The cooled air introduced into the driver's compartment 1 is sucked in again by the air conditioner 3 and branches in the second air guide 13. A first part of the air is sucked again into the cab air-handling device 8 by the cab ventilators 9 and cooled again there (represented by arrow 23). This leads to a cooling circulation of the air in the driver's compartment. 1 The cooled air exiting the evaporator 4 down into the driver's compartment 1 thus contains portions of the fresh air as well as portions of the circulated air (represented by arrows 22). A second portion of the air, approximately corresponding to the amount of fresh air continuously supplied, is drawn through the engine room fan 6 into the engine room air treatment device 11, with the intake air initially passed through the engine room filtration 5 (shown by arrow 24). The cleaned air then passes through the air duct 12 and the check valve 7 in the largely dense engine room 2 (shown by arrow 25). Through the engine room fan 6 air is continuously introduced into the engine room 2. This leads to an increased air pressure in the environment
Maschinenraum 2. Allenfalls durch Undichtigkeiten im Gehäuse des Maschinenraumes 2 kann die Luft aus dem Maschinenraum 2 in die Umgebung entweichen. Daher genügt eine geringe Luftströmung in den Maschinenraum 2 hinein, um den Überdruck zu erzeugen. Da diese Luft bereits als Frischluft in den Führerraum 1 eingeleitet wurde, werden wesentlich geringere Mengen an Verunreinigungen und Feuchtigkeit in den Maschinenraum 2 weitergeleitet als bei direkter Zuführung von Frischluft in den Engine room 2. At best, through leaks in the housing of the engine room 2, the air can escape from the engine room 2 in the environment. Therefore, a small flow of air into the engine room 2 is sufficient to generate the overpressure. Since this air has already been introduced as fresh air in the cab 1, much smaller amounts of impurities and moisture in the engine room 2 are forwarded as in direct supply of fresh air in the
Maschinenraum 2. Falls der Maschinenraumlüfter 6 ausfallen sollte, würde sich der Überdruck im Maschinenraum 2 über den Luftkanal 12 schnell abbauen. Um dies zu vermeiden, ist die Rückschlagklappe 7 vorgesehen, die die Öffnung zwischen dem Führerraum 1 und dem Maschinenraum 2 schließt. Die in den Maschinenraum 2 eintretende Luft ist durch die mehrfache Filterung besonders sauber. Engine room 2. If the engine room ventilator 6 should fail, the overpressure in the engine room 2 would rapidly degrade via the air duct 12. To avoid this, the non-return valve 7 is provided, which closes the opening between the driver's compartment 1 and the engine room 2. The entering into the engine room 2 air is particularly clean through the multiple filtering.
