Description

La présente invention concerne un dispositif de climatisation pour véhicules notamment pour voitures ferroviaires.The present invention relates to an air conditioning device for vehicles, in particular for railway cars.

On a décrit dans le brevet français 2 461 606 une installation de climatisation pour voitures ferroviaires comprenant un ventilateur soufflant de l'air froid ou réchauffé dans un conduit s'étendant à la partie inférieure de la face latérale intérieure de la voiture. Ce conduit débouche dans des gaines pour répartir l'air froid ou réchauffé vers le haut de la face latérale intérieure de la voiture et vers le bas de cette dernière.French patent 2,461,606 describes an air conditioning installation for railway cars comprising a fan blowing cold air or heated air in a duct extending to the lower part of the interior lateral face of the car. This duct opens into ducts to distribute the cold or heated air up the interior side of the car and down from the latter.

Ces gaines de répartition comprennent dans une zone intermédiaire une ouverture par laquelle l'air contenu dans la voiture est aspiré à l'intérieur des gaines de répartition précitées.These distribution sheaths comprise in an intermediate zone an opening through which the air contained in the car is sucked inside the aforementioned distribution sheaths.

Ainsi, l'installation comprend le long de chaque paroi latérale de la voiture une succession de gaines verticales de répartition d'air vers le haut et vers le bas.Thus, the installation comprises along each side wall of the car a succession of vertical air distribution ducts up and down.

Par ailleurs, le conduit comprend au droit de chaque gaine une ouverture de sortie d'air, munie de moyens de réglage du débit de cet air. L'air sortant de ces ouvertures est dirigé sensiblement parallèlement au plancher de la voiture et pratiquement au niveau des pieds de l'utilisateur.Furthermore, the duct comprises at the right of each sheath an air outlet opening, provided with means for adjusting the flow of this air. The air exiting from these openings is directed substantially parallel to the floor of the car and practically at the level of the feet of the user.

Cette installation de climatisation présente un certain nombre d'inconvénients.This air conditioning installation has a number of drawbacks.

En premier lieu, cette installation est mal adaptée aux voitures ferroviaires modernes non compartimentées, c'est-à-dire qui ne présentent pas de cloisons transversales de séparation.Firstly, this installation is ill-suited to modern non-compartmentalized railway cars, that is to say which do not have transverse partition walls.

Ainsi, dans le cas de telles voitures, l'air débouche à l'intérieur de celles-ci par des ouvertures séparées les unes des autres qui ne permettent pas de réaliser un brassage régulier et homogène de l'air.Thus, in the case of such cars, the air opens inside of them by openings separated from each other which do not allow a regular and homogeneous mixing of the air.

Cette irrégularité du brassage de l'air crée ainsi des discontinuités de débit et de température de l'air qui nuisent au confort des voyageurs.This irregularity in the mixing of air thus creates discontinuities in air flow and temperature which affect passenger comfort.

Ces voyageurs, du fait de leur immobilité sont en effet très sensibles aux différences de températures même minimes ainsi qu'aux courants d'air ponctuels.These travelers, because of their immobility, are in fact very sensitive to even small temperature differences as well as to occasional drafts.

Par ailleurs, la demanderesse a constaté que les voyageurs étaient particulièrement gênés par les courants d'air ponctuels soufflés directement au niveau des pieds des voyageurs.Furthermore, the Applicant has found that the travelers were particularly bothered by the occasional drafts of air blown directly at the feet of the travelers.

Le but de la présente invention est de remédier aux inconvénients de l'installation connue ci-dessus, en proposant un dispositif de climatisation qui soit mieux adapté aux voitures ferroviaires modernes non compartimentées et qui permette d'obtenir un brassage régulier et homogène de l'air assurant un confort optimal aux voyageurs.The object of the present invention is to remedy the drawbacks of the installation known above, by proposing an air conditioning device which is better suited to modern non-compartmentalized railway cars and which makes it possible to obtain regular and homogeneous mixing of the air ensuring optimal comfort for travelers.

Le dispositif de climatisation visé par l'invention comprend au moins un ventilateur soufflant de l'air froid ou rechauffé dans un conduit s'étendant à la partie inférieure de la face latérale intérieure du véhicule, ce conduit débouchant dans des moyens pour répartir l'air froid ou réchauffé vers le haut de ladite face latérale intérieure et vers le bas de cette dernière, lesdits moyens de répartition comprenant dans une zone intermédiaire une ouverture par laquelle l'air contenu dans le véhicule est aspiré à l'intérieur desdits moyens de répartition.The air conditioning device targeted by the invention comprises at least one fan blowing cold air or heated air in a duct extending to the lower part of the interior lateral face of the vehicle, this duct opening into means for distributing the cold or heated air upwards and downwards from said inner lateral face, said distribution means comprising in an intermediate zone an opening through which the air contained in the vehicle is drawn inside said distribution means .

Suivant l'invention, ce dispositif est caractérisé en ce que le conduit précité débouche à sa partie supérieure dans un espace délimité par deux parois parallèles adjacentes à la face latérale du véhicule et s'étendant sans discontinuité sur toute la longueur du véhicule, cet espace débouchant à sa partie supérieure à l'intérieur du véhicule par des ouvertures situées sensiblement au niveau des fenêtres du véhicule, en ce que le conduit présente sur sa face latérale adjacente à l'intérieur du véhicule un passage de sortie d'air s'étendant sensiblement sur toute la longueur du véhicule et en ce que la paroi adjacente à l'intérieur du véhicule de l'espace précité présente près du conduit une fente s'étendant sur sensiblement toute la longueur du véhicule par laquelle l'air contenu dans le véhicule est aspiré dans l'espace précité.According to the invention, this device is characterized in that the above-mentioned conduit opens at its upper part into a space delimited by two parallel walls adjacent to the lateral face of the vehicle and extending without discontinuity over the entire length of the vehicle, this space opening at its upper part inside the vehicle by openings located substantially at the level of the windows of the vehicle, in that the duct has on its side face adjacent to the interior of the vehicle an air outlet passage extending substantially all over length of the vehicle and in that the wall adjacent to the interior of the vehicle of the aforementioned space has near the duct a slot extending over substantially the entire length of the vehicle by which the air contained in the vehicle is sucked into the above space.

Le fait que l'espace de répartition de l'air s'étende sur sensiblement toute la longueur du véhicule permet au dispositif selon l'invention de s'adapter parfaitement à la continuité de la face latérale du véhicule, en particulier d'une voiture ferroviaire non compartimentée. Ainsi, le véhicule peut par exemple être équipé de sièges espacés les uns des autres d'une distance quelconque qui est tout à fait indépendante de la présence du dispositif de climatisation.The fact that the air distribution space extends over substantially the entire length of the vehicle allows the device according to the invention to adapt perfectly to the continuity of the lateral face of the vehicle, in particular of a car non-compartmentalized railway. Thus, the vehicle can for example be equipped with seats spaced from each other by any distance which is entirely independent of the presence of the air conditioning device.

Par ailleurs, étant donné que l'espace précité est parfaitement continu, l'air sortant du dispositif est diffusé à l'intérieur du véhicule à une température et un débit homogènes.Furthermore, since the aforementioned space is perfectly continuous, the air leaving the device is diffused inside the vehicle at a uniform temperature and flow.

D'autre part, etant donné que l'air sortant par le bas du dispositif débouche du conduit par une fente sensiblement continue, le débit et la température de cet air sont parfaitement réguliers tout le long du vehicule et le voyageur ne risque pas de ressentir au niveau de ses pieds des courants d'air ponctuels désagréables.On the other hand, since the air exiting from the bottom of the device emerges from the conduit through a substantially continuous slot, the flow and the temperature of this air are perfectly regular all along the vehicle and the traveler is not likely to feel at his feet unpleasant punctual drafts.

Selon une version avantageuse de l'invention, la paroi latérale du conduit présente à sa partie supérieure des ouvertures de sortie d'air qui débouchent dans un compartiment qui s'ouvre vers le bas par une fente s'étendant de façon continue sur sensiblement toute la longueur du véhicule.According to an advantageous version of the invention, the lateral wall of the duct has at its upper part air outlet openings which open into a compartment which opens downwards through a slot extending continuously over substantially all of the length of the vehicle.

Etant donné que cette fente dirige l'air froid vers le bas, c'est-à-dire vers le plancher, cet air ne rencontre pas directement les pieds des voyageurs, de sorte que ceux-ci ne sont pas gênés par l'air sortant à la partie inférieure du dispositif.Since this slit directs the cold air downwards, that is to say towards the floor, this air does not directly meet the feet of the travelers, so that they are not obstructed by the air coming out at the bottom of the device.

Le dispositif conforme à l'invention permet de réaliser un brassage de l'air en forme de rouleaux continus superposés, l'un de ces rouleaux étant formé par l'air débouchant en bas du dispoitif par une fente continue et retournant de celui-ci par la fente s'étendant à la base de l'espace formé par les deux parois parallèles et l'autre rouleau étant formé par l'air sortant par le haut du dispositif et retournant dans celui-ci par la fente précitée. La continuité de ces rouleaux permet un brassage efficace de l'air qui affecte la totalité du volume intérieur du véhicule.The device according to the invention makes it possible to perform an air mixing in the form of superimposed continuous rollers, one of these rollers being formed by the air emerging at the bottom of the device by a continuous slit and returning from it by the slit extending at the base of the space formed by the two parallel walls and the other roller being formed by the air exiting from the top of the device and returning therein through the aforementioned slot. The continuity of these rollers allows efficient mixing of the air, which affects the entire interior volume of the vehicle.

D'autres particularités et avantages de l'invention apparaîtront encore dans la description ci-après.Other features and advantages of the invention will appear in the description below.

Aux dessins annexés, donnés à titre d'exemples non limitatifs :

  • - la figure 1 est une vue schématique en perspective montrant un dispositif de climatisation conforme à l'invention à l'intérieur d'une voiture ferroviaire,
  • - la figure 2 est une vue en coupe transversale du dispositif de climatisation conforme à l'invention.
In the appended drawings, given by way of nonlimiting examples:
  • FIG. 1 is a schematic perspective view showing an air conditioning device according to the invention inside a railway car,
  • - Figure 2 is a cross-sectional view of the air conditioning device according to the invention.

En référence aux figures 1 et 2 annexées, le dispositif de climatisation conforme à l'invention comprend un ventilateur 1 disposé sous le plancher 3 de la voiture ferroviaire 2, soufflant de l'air froid ou réchauffé dans un conduit 4 s'étendant à la partie inférieure de la face latérale intérieure 5 de la voiture 2. Ce conduit 4 débouche dans des moyens pour répartir l'air froid ou réchauffé vers le haut de la face latérale intérieure 5 et vers le bas de cette dernière.Referring to Figures 1 and 2 attached, the air conditioning device according to the invention comprises a fan 1 disposed under the floor 3 of the railway car 2, blowing cold air or heated in a duct 4 extending to the lower part of the inner side face 5 of the car 2. This duct 4 opens into means for distributing the cold or heated air upwards from the inner side face 5 and downwards from the latter.

Ces moyens de répartition comprennent dans une zone intermédiaire une ouverture 6 par laquelle l'air contenu dans la voiture 2 est aspiré à l'intérieur de ces moyens de répartition.These distribution means comprise in an intermediate zone an opening 6 through which the air contained in the car 2 is sucked inside these distribution means.

Conformément à l'invention, le conduit 4 débouche à sa partie supérieure dans un espace 7 délimité par deux parois parallèles 8, 9 adjacentes à la face latérale 5 de la voiture 2 et s'étendant sans discontinuité sur toute la longueur de cette voiture.In accordance with the invention, the duct 4 opens at its upper part into a space 7 delimited by two parallel walls 8, 9 adjacent to the lateral face 5 of the car 2 and extending without discontinuity over the entire length of this car.

L'espace 7 débouche à sa partie supérieure à l'intérieur de la voiture, par des ouvertures allongées 10 situées sensiblement au niveau du bord inférieur des fenêtres 11 de la voiture.The space 7 opens at its upper part inside the car, by elongated openings 10 located substantially at the lower edge of the windows 11 of the car.

Le conduit 4 présente (voir figure 2), sur sa face latérale 12 adjacente à l'intérieur de la voiture un passage 13 de sortie d'air s'étendant sur toute la longueur de la voiture.The duct 4 has (see FIG. 2), on its lateral face 12 adjacent to the interior of the car, an air outlet passage 13 extending over the entire length of the car.

Par ailleurs, la paroi 9 adjacente à l'intérieur de la voiture de l'espace 7 précité présente près du conduit 4 une fente 6 s'étendant sur toute la longueur de la voiture par laquelle l'air contenu dans cette voiture est aspiré dans l'espace 7 précité.Furthermore, the wall 9 adjacent to the interior of the car in the aforementioned space 7 has, near the duct 4, a slot 6 extending over the entire length of the car by which the air contained in this car is drawn in. space 7 above.

On voit d'autre part sur la figure 2, que la paroi latérale 12 du conduit 4 présente à sa partie supérieure des ouvertures 15 de sortie d'air de faible section constituant des éjecteurs qui débouchent dans un compartiment 16 qui s'ouvre vers le bas par une fente 13 s'étendant de façon continue sur toute la longueur de la voiture 2.On the other hand, it can be seen in FIG. 2 that the side wall 12 of the duct 4 has, at its upper part, air outlet openings 15 of small cross section constituting ejectors which open into a compartment 16 which opens towards the bottom by a slot 13 extending continuously over the entire length of the car 2.

De plus, le conduit 4 présente sur sa face supérieure 17 adjacente à l'espace 7 des ouvertures 18 de faible section, constituant des éjecteurs qui débouchent dans l'espace 7.In addition, the duct 4 has on its upper face 17 adjacent to the space 7 openings 18 of small section, constituting ejectors which open into the space 7.

Comme indiqué sur la figure 2, la partie supérieure du conduit 4 présente une zone 19 délimitée par des parois 20, 21 qui convergent vers le haut, le sommet 17 de cette zone presentant les ouvertures 18 qui débouchent dans l'espace 7.As shown in FIG. 2, the upper part of the duct 4 has a zone 19 delimited by walls 20, 21 which converge upwards, the top 17 of this zone having the openings 18 which open into the space 7.

Par ailleurs, la fente 6 par laquelle l'air contenu dans la voiture 2 est aspiré dans l'espace 7 précité est située sensiblement au droit des ouvertures 18 de sortie d'air qui débouchent dans cet espace 7.Furthermore, the slot 6 through which the air contained in the car 2 is sucked into the aforementioned space 7 is situated substantially in line with the air outlet openings 18 which open into this space 7.

On voit également sur la figure 2 qu'une résistance électrique de chauffage d'appoint 22 est disposée légèrement en amont des ouvertures 18 qui débouchent dans l'espace 7. Cette résistance 22 est fixée contre la paroi 21 de la zone convergente 19.It can also be seen in FIG. 2 that an electrical auxiliary heating resistor 22 is disposed slightly upstream of the openings 18 which open into the space 7. This resistor 22 is fixed against the wall 21 of the converging zone 19.

En outre, les ouvertures 10 de l'espace 7 qui débouchent sensiblement au niveau des fenêtres 11 et la fente 13 du conduit 4 qui débouche vers le bas, comportent des lamelles orientables 23, 24 de réglage de la direction de sortie de l'air.In addition, the openings 10 in the space 7 which open out substantially at the level of the windows 11 and the slot 13 in the duct 4 which opens downwards, comprise orientable strips 23, 24 for adjusting the direction of air outlet. .

Le compartiment 16 situé en aval des ouvertures de sortie 15 et en amont de la fente 13 présente une paroi extérieure raccordée à la paroi supérieure 25 du conduit 4 par une partie arrondie 26 qui guide l'air vers la fente 13.The compartment 16 located downstream of the outlet openings 15 and upstream of the slot 13 has an outer wall connected to the upper wall 25 of the duct 4 by a rounded part 26 which guides the air towards the slot 13.

De plus, la paroi latérale 12 du conduit 4 présente à sa partie inférieure une zone arrondie 27 qui dévie latéralement l'air vers l'intérieur de la voiture.In addition, the side wall 12 of the duct 4 has at its lower part a rounded area 27 which laterally deflects the air towards the interior of the car.

On va maintenant décrire le fonctionnement du dispositif de climatisation conforme à l'invention.We will now describe the operation of the air conditioning device according to the invention.

L'air chaud ou froid est soufflé à un débit réglable en fonction des besoins, par le ventilateur 1 dans le conduit 4 qui s'étend à la partie inférieure de la face latérale 5 de la voiture. A partir de ce conduit 4, l'air est soufflé vers le haut par les éjecteurs 18 et vers le bas de la voiture par les éjecteurs 15.The hot or cold air is blown at a flow rate adjustable as required, by the fan 1 in the duct 4 which extends to the lower part of the side face 5 of the car. From this duct 4, the air is blown upwards by the ejectors 18 and downwards from the car by the ejectors 15.

Du fait de la dépression créée par le soufflage de l'air par les éjecteurs 18, l'air contenu dans la voiture est aspiré dans l'espace 7 par la fente 6. Ainsi, l'air sortant par les ouvertures 10 est constitué par un mélange d'air venant du conduit 4 et de l'intérieur de la voiture.Due to the vacuum created by the blowing of air by the ejectors 18, the air contained in the car is sucked into space 7 by the slot 6. Thus, the air exiting through the openings 10 is constituted by a mixture of air coming from duct 4 and from inside the car.

Du fait que l'air soufflé par les éjecteurs 15 est dévié vers le bas par la paroi 22, les pieds des voyageurs ne sont pas directement exposé à un courant d'air local désagréable.Because the air blown through the ejectors 15 is deflected downward through the wall 22, the feet of the travelers are not directly exposed to an unpleasant local air current.

Du fait de l'aspiration créée par la fente 6, l'air soufflé en bas forme un rouleau de brassage inférieur (voir flèche F₁ sur la figure 2) tandis que l'air soufflé en haut forme un rouleau de brassage supérieur (voir flèche F₂ sur la figure 2). Ces deux rouleaux de brassage permettent d'obtenir un brassage uniforme qui affecte sensiblement tout le volume intérieur de la voiture et procurent ainsi aux voyageurs un confort accru.Due to the suction created by the slot 6, the air blown at the bottom forms a lower stirring roller (see arrow F₁ in FIG. 2) while the air blown at the top forms a upper stirring roller (see arrow F₂ in Figure 2). These two brewing rollers allow to obtain a uniform mixing which affects substantially the entire interior volume of the car and thus provides travelers with increased comfort.

Par ailleurs, les deux parois continues 8 et 9 délimitant l'espace 7 apportent à la face latérale intérieure 5 de la voiture une isolation thermique et acoustique complémentaire.Furthermore, the two continuous walls 8 and 9 delimiting the space 7 provide the interior lateral face 5 of the car with additional thermal and acoustic insulation.

La résistance électrique 22 placée dans la zone 19 permet si nécessaire de réchauffer l'air qui est soufflé dans l'espace 7.The electrical resistance 22 placed in the zone 19 makes it possible, if necessary, to heat the air which is blown into the space 7.

Bien entendu, l'invention n'est pas limitée à l'exemple de réalisation que l'on vient de décrire et on peut apporter à celui-ci de nombreuses modifications sans sortir du cadre de l'invention.Of course, the invention is not limited to the embodiment which has just been described and many modifications can be made to it without departing from the scope of the invention.

Ainsi, le conduit inférieur 4 du dispositif peut être prolongé vers l'intérieur du véhicule de sorte que sa face supérieure constitue le plancher du véhicule sur lequel peuvent être fixés directement les sièges.Thus, the lower duct 4 of the device can be extended towards the interior of the vehicle so that its upper face constitutes the floor of the vehicle on which the seats can be fixed directly.

Par ailleurs, les orifices d'éjection 15 pratiqués sur la paroi verticale 12 du conduit 12, pourraient être ménagés sur une paroi perpendiculaire à celle-ci s'étendant dans l'espace 16.Furthermore, the ejection orifices 15 formed on the vertical wall 12 of the conduit 12 could be formed on a wall perpendicular to the latter extending in the space 16.

D'autre part, les orifices d'éjection 18 ménagés dans la paroi 17 située à la base du compartiment vertical 7 pourraient être plus proches les uns des autres au niveau des fenêtres 11 qu'ailleurs, pour permettre un débit d'air chaud ou froid plus important au niveau des fenêtres et compenser ainsi les déperditions thermiques plus importantes à leur niveau qu'ailleurs.On the other hand, the ejection orifices 18 formed in the wall 17 situated at the base of the vertical compartment 7 could be closer to each other at the level of the windows 11 than elsewhere, to allow a flow of hot air or more cold at the windows and thus compensate for the greater heat losses at their level than elsewhere.
