Abstract

1. An arrangement for air-conditioning the passenger space of passenger-train carriages by feeding in treated air by way of at least one duct (3) which extends in the roof space along the length of the carriage and by roof-sided exhaustion of the spent air by way of a recirculated air return (9), in which respect the air injection and air exhaustion openings (5 or 8 respectively) are grouped according to carriage space halves and these groups are in each case associated with air treatment means (20) of their own, characterized by a pairing of air injection openings (5) with air exhaustion openings (8) in roof-sides positioning in such a way that in each case after a circulation of feed air rotating inwards of the space has begun at the roof side in the passenger space eventually impure air can be led off again at the roof side into the recirculated air return (9).

Description

Die Erfindung betrifft eine Einrichtung zum Klimatisieren des Fahrgastraumes von Reisezugwagen gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a device for air conditioning the passenger compartment of passenger cars according to the preamble of claim 1.

Bei der derzeit in europäischen Eisenbahnpersonenwagen zum Klimatisieren bevorzugten Zulufteinblasung senkrecht nach oben entlang den Fensterflächen besteht bekanntlich insbesondere im Kühlbetrieb das Problem von Zuglufterscheinungen. Denn die Forderung nach Kaltluftverteilung über den gesamten Fahrgastraum bedingt naturgemäß bei aufwärts gerichteter Zulufteinblasung eine relativ hohe Blasgeschwindigkeit. Entsprechend müßte bei dachseitiger Zulufteinblasung im Heizbetrieb auch mit einer hohen Blasgeschwindigkeit gearbeitet werden mit der zwangsläufigen Folge von Belästigungen der Fahrgäste.As is well known, the problem of draft phenomena exists, particularly in cooling operation, in the supply air injection that is currently preferred for air conditioning vertically upwards along the window surfaces in European railway passenger cars. Because the demand for cold air distribution over the entire passenger compartment naturally means that the supply air is blown upwards and therefore requires a relatively high blowing speed. Accordingly, in the case of roof-side supply air injection in heating mode, it would also be necessary to work at a high blowing speed, with the inevitable consequence of nuisance to the passengers.

Das darüberhinaus durch die FR-A-2 021 038 bekannte Klimatisierungsprinzip des dachseitigen Zu- und Ableitens von Luft ist auch nicht frei von Problemen, da Geruchsbelästigungen von Fahrgästen insbesondere durch Tabakrauch nur durch das Einrichten von Nichtraucherräumen bzw. -abteilen vermeidbar sind.The air conditioning principle of supplying and discharging air from the roof, which is also known from FR-A-2 021 038, is also not without problems, since odor nuisance to passengers, in particular from tobacco smoke, can only be avoided by setting up non-smoking rooms or compartments.

Der Erfindung liegt die Aufgabe zugrunde, bei einer Einrichtung der eingangs genannten Art grundsätzlich Belästigungen der Fahrgäste durch Klimaluft weitgehend auszuschließen.The invention has for its object to fundamentally rule out nuisance to passengers by air conditioning in a device of the type mentioned.

Diese Aufgabe ist gemäß dem Kennzeichen des Patentanspruchs 1 gelöst, also durch einen im Wege der dachseitigen Paarung von Lufteinblas-und Luftabsaugöffnungen bewirkten Zuluftkreislauf im Fahrgastraum, unter Bildung von mehreren (wenigstens zwei) Klimazonen eigener Luftaufbereitung.This object is achieved in accordance with the characterizing part of patent claim 1, that is to say by means of a supply air circuit in the passenger compartment brought about by the pairing of air inlet and air extraction openings on the roof side, with the formation of several (at least two) climate zones of its own air conditioning.

In Weiterbildung der Erfindung werden hierbei. Großraum-Reisezugwagen Lufteinblas- und Luftabsaugöffnungen vorzugsweise an beiden Wagenlängsseiten im Sinne der Erzeugung je eines Zuluftkreislaufes gesonderter Luftauibereitung in den Raumhälften beiderseits der Wagenlängsmittenebene aufweisen, dagegen wird der Abteil-Reisezugwagen mit solchen Öffnungen an beiden Abteilwänden im Sinne der Erzeugung je eines gesonderten Zuluftkreislaufes in den Raumhälften beiderseits der Abteillängsmittenebene versehen, beispielsweise jeweils bei einer eigenen Luftaufbereitung der Wagenraumhälften beiderseits der Wagenquermittenebene.In a further development of the invention. Large-capacity passenger coaches have air injection and air extraction openings, preferably on both long sides of the wagon, in order to create a supply air circuit for separate air conditioning in the halves of the room on both sides of the longitudinal center plane, while the compartment passenger coach will have openings on both compartment walls in the sense of creating a separate supply air circuit in each Provide halves of the room on both sides of the longitudinal center plane of the compartment, for example, each with its own air conditioning of the car halves on both sides of the central plane of the car.

Der in Fig. 1 dargestellte Fahrgastraum eines Reisezugwagens mit durch einen offenen Gang getrennten Sitzen 1 beiderseits der Wagenlängsmittenebene 2, also ein sog. Großraum ist über zwei im Wagendachraum der Wagenlänge nach sich erstreckende Zuluftkanäle 3 mit einem mit Frischluft versorgten Klimaaggregat 20 verbunden, z. B. eine bekannte Einheit einerseits aus einer Kompressor-Kältemaschine und andererseits aus Luftfiltern, einem Verdampfer, Lufterhitzern, Ventilatoren und dgl., wovon in Fig. 4 (bzw.5) bloß die im Wagendachraum sitzenden Geräte angedeutet sind. Von den Zuluftkanälen 3 zweigen Verteilungskanäle 4 ab, die über Verteilungskästen 18 in Lufteinblasöffnungen 5 münden. Die Verteilungskästen 18 können bei ausreichendem Raumangebot auch die Funktion der Zuluft- und Verteilungskanäle 3 bzw. 4 übernehmen, d.h. dann können letztere als solche eingespart werden.The passenger compartment of a passenger car shown in FIG. 1 with seats 1 separated by an open aisle on either side of the longitudinal center plane 2, that is to say a large space, is connected to an air conditioning unit 20 supplied with fresh air via two supply air ducts 3 extending in the roof space along the length of the vehicle. B. a known unit on the one hand from a compressor refrigerator and on the other hand from air filters, an evaporator, air heaters, fans and the like. Of which in Fig. 4 (resp. 5) only the devices sitting in the car roof space are indicated. Distribution ducts 4 branch off from the supply air ducts 3 and open into air inlet openings 5 via distribution boxes 18. The distribution boxes 18 can also take over the function of the supply air and distribution channels 3 and 4 if there is sufficient space, i.e. then the latter can be saved as such.

Gemäß Fig. 1 sind die Lufteinblasöffnungen 5 vorzugsweise am Boden 6 von raumdeckenseitigen (Klein-) Gepäckablagen so ausgerichtet, daß diese für die angeblasene Luft eine Leitfunktion erfüllen; andernfalls kann die jeweilige Lufteinblasöffnung auch über der Gepäckablage unmittelbar an der Raumdecke 7 positioniert sein. Durch eine Paarung dieser Lufteinblasöffnungen 5 mit je einer in deren Nähe an der Wagenseitenwand positionierten Luftabsaugöffnung 8 wird in der durch die Pfeile veranschaulichten Weise in jeder Hälfte des Fahrgastraumes ein raumeinwärtsdrehender Luftkreislauf bewirkt, wobei die Abluft der Luftabsaugöffnungen 8 über eine Umluftrückführung 9 zum Klimaaggregat gelangt; als Umluftrückführung wird vorzugsweise der verbleibende Dachhohlraum genutzt. Bei einem solchen Luftkreislauf nach Art einer Luftwalzenbildung ist eine Belästigung der Fahrgäste durch Blasluft weitgehendst ausgeschlossen, wobei die dargestellte Erzeugung zweier gegensinnig rotierender Luftwalzen, d. h. je eines gesonderten Zuluftkreislaufs in den Wagenraumhälften beiderseits der Wagenlängsmittenebene 2 Geruchsbelästigungen der Fahrgäste der einen Raumhälfte beispielsweise durch rauchende Fahrgäste der anderen Raumhälfte auf das Geringstmögliche reduziert. Luftverunreinigungen werden nicht verschleppt, sondern auf kürzestem Wege abgesaugt. In diesem Sinne ist schließlich gemäß Fig. 4 eine Gruppierung der Lufteinblas- und Luftabsaugöffnungen 5 bzw. 8 in dem Sinne vorgenommen, daß je Wagenraumhälfte der Zuluftkreislauf einer gesonderten Luftaufbereitung zugeordnet ist. Das wird gemäß Fig. 4 zum einen durch den Anschluß des einzelnen Zuluftkanals 3 an jeweils ein eigenes Klimaaggregat 20 und zum anderen durch eine im Dachraum in der Wagenlängsmittenebene verlaufende Trennwand 2.1 zur Unterteilung der Umluftrückführung 9 erreicht. Es versteht sich, daß bedarfsweise die Luftaufbereitung auch je Wagenraumhälfte beiderseits der Wagenquermittenebene gesondert geschehen kann.According to FIG. 1, the air injection openings 5 are preferably aligned on the floor 6 of (small) luggage racks on the ceiling, in such a way that they perform a guiding function for the blown air; otherwise, the respective air injection opening can also be positioned directly on the ceiling 7 above the luggage rack. By pairing these air injection openings 5, each with an air extraction opening 8 positioned in the vicinity of them on the side wall of the vehicle, an air circuit rotating inward is effected in each half of the passenger compartment in the manner illustrated by the arrows, the exhaust air from the air extraction openings 8 reaching the air conditioning unit via a recirculation air recirculation 9; the remaining roof cavity is preferably used as air recirculation. In such an air circuit in the manner of an air roller formation, annoyance to the passengers by blown air is largely ruled out, the illustrated generation of two counter-rotating air rollers, that is to say a separate supply air circuit in the halves of the vehicle compartment on both sides of the longitudinal center plane of the vehicle, 2 odor nuisance to the passengers in one half of the room, for example by smoking passengers other half of the room reduced to the minimum possible. Air pollution is not carried over, but extracted in the shortest possible way. In this sense, finally, according to FIG. 4, a grouping of the air injection and air extraction openings 5 and 8 is carried out in the sense that the supply air circuit is assigned to a separate air treatment per half of the vehicle compartment. This is achieved according to FIG. 4 on the one hand by connecting the individual supply air duct 3 to its own air conditioning unit 20 and on the other hand by means of a partition 2.1 running in the roof space in the longitudinal center plane of the car for dividing the recirculation air recirculation 9. It is understood that if necessary the Air treatment can also be done separately for each half of the car space on both sides of the car cross plane.

Gemäß Fig. 2 und 3 kommt das Klimatisierungsprinzip gemäß der Erfindung ebensogut für Abteil-Reisezugwagen in Betracht, wobei gemäß Fig. 3 Lufteinblas- und Luftabsaugöffnungen 5 bzw. β an beiden Abteiltrennwänden 10 im Sinne der Erzeugung je eines gesonderten Zuluftkreislaufes in den Raumhälften beiderseits der Abteillängsmittenebene 11 bevorzugt werden. Dabei kann gemäß Fig. 2 Fortluft über Lüftungsgitter 12 in den Wagenseitengang geleitet und hierin zum Klimatisieren genutzt werden unter Absaugung einerseits in die betreffenden dachseitigen Umluftrückführungen 9 und andererseits in einen bodenseitigen Fortluftkanal 13 (Fig. 2).According to FIGS. 2 and 3, the air conditioning principle according to the invention is equally suitable for compartment passenger coaches, whereby according to FIG. 3 air injection and air extraction openings 5 and β on both compartment partitions 10 in the sense of generating a separate supply air circuit in the halves of the room on both sides of the Component longitudinal center plane 11 are preferred. 2, exhaust air can be guided into the side aisle via ventilation grilles 12 and used for air conditioning therein, with suction on the one hand into the relevant roof-side recirculation air recirculation 9 and on the other hand into a floor-side exhaust air duct 13 (FIG. 2).

Die Möglichkeit der bodenseitigen Fortluftabsaugung ist selbstverständlich auch innerhalb des Abteiles durch einen entsprechenden Fortluftkanal 14 realisierbar, wobei (außer Lüftungsgittern) hieran z.B. über Stichleitungen zusätzlich angeschlossene Luftabsaugöffnungen 15 vorzugsweise unterhalb der Sitzflächen der beiden Sitzreihen angeordnet sind; diese Anordnung steigert die Wirksamkeit der Abteil-Luftdurchspülung ganz beträchtlich. Die Fortluft könnte hierbei selbstverständlich auch, wie in Fig.1 angedeutet, zur Fußbodenheizung genutzt werden, wobei dann bloß die an die bodenseitigen Luftabsaugöffnungen 15 angeschlossenen Fortluftkanäle 13, 14 über im Fußboden sich erstreckende Leitungen 16 und einen diesen nachgeschalteten Ventilator 17 mit dem Unterflurraum des Reisezugwagens zu verbinden sind. Die hierdurch zugleich erzielte Klimatisierung des Unterflurraumes reduziert die Wärmeverluste, wobei der durch die Lufteinblasung entstehende Überdruck im Unterflurraum dort zugleich das Eindringen von Verunreinigungen weitgehend verhindert. Sofern das vorgenannte Klimaaggregat 20 auf entsprechenden Druck ausgelegt ist, kann auf die vorgenannte bodenseitige Luftabsaugung verzichtet werden, d.h., es genügen bodenseitige Luftöffnungen zur bloßen Abführung von Fortluft.The possibility of exhaust air extraction from the floor is of course also possible within the compartment by means of a corresponding exhaust air duct 14, with (except ventilation grilles) e.g. Air suction openings 15 additionally connected via stub lines are preferably arranged below the seat surfaces of the two rows of seats; this arrangement significantly increases the effectiveness of the compartment air purge. The exhaust air could of course also, as indicated in Fig.1, be used for underfloor heating, in which case only the exhaust air ducts 13, 14 connected to the bottom-side air extraction openings 15 via lines 16 extending in the floor and a fan 17 connected downstream to the underfloor space of the Passenger cars are to be connected. The air conditioning of the underfloor space which is thereby achieved at the same time reduces the heat losses, the overpressure in the underfloor space resulting from the air injection largely preventing the ingress of contaminants there. If the above-mentioned air conditioning unit 20 is designed for appropriate pressure, the aforementioned bottom-side air extraction can be dispensed with, i.e. bottom-side air openings are sufficient for the mere removal of exhaust air.

Selbstverständlich kann bei entsprechender Anordnung der Lufteinblas- und Luftabsaugöffnungen erforderlichenfalls auch im Abteil, wie im Großraum, ein quer zur Wagenlängsachse gerichteter Luftkreislauf erzeugt werden. Im übrigen zeigt Fig. 5, daß im Abteil-Reisezugwagen beispielsweise zwei Klimazonen auch durch eine in der Wagenquermittenebene im Dachraum die Umluftrückführung 9 unterteilende Trennwand 2.2 erreichbar ist, wobei dann die Zuluftkanäle 3 sich je Wagenhälfte von dem betreffenden Klimaaggregat 20 bis zu dieser Trennwand erstrecken. Eine derartige Trennung der Luftaufbereitung der beiden Wagenraumhälften ermöglicht eine saubere Trennung von Rauchern und Nichtrauchern. Wie schließlich bei einem Abteil-Reisezugwagen bedarfsweise durch entsprechende Trennwände und Luftführungen im Dachraum mehr als zwei Klimazonen erreichbar sind, so ist dies natürlich auch bei dem Großraum-Reisezugwagen möglich, hier z. B. in einfacher Weise durch eine zusätzliche Trennung entsprechend Fig. 5 mit doppelseitiger Luftzuführung des jeweiligen Klimaaggregates.Of course, with an appropriate arrangement of the air injection and air extraction openings, an air circuit directed transversely to the longitudinal axis of the car can also be produced in the compartment, as in the larger area, if necessary. 5 shows that in the compartment passenger coach, for example, two climatic zones can also be reached by a partition 2.2 dividing the recirculation air recirculation 9 in the roof cross plane in the roof space, the supply air ducts 3 then extending from the relevant air conditioning unit 20 to the partition wall per half of the coach . Such a separation of the air conditioning of the two halves of the car enables a clean separation of smokers and non-smokers. Finally, as with a compartment coach, more than two climatic zones can be reached if necessary by means of appropriate partition walls and air ducts in the roof space, this is of course also possible with the coach. B. in a simple manner by an additional separation according to FIG. 5 with double-sided air supply of the respective air conditioning unit.

Die Lufteinblasung kann im übrigen auch nach dem Injektionsprinzip erfolgen.The air injection can also be done according to the injection principle.
