Description

La présente invention concerne une plateforme de véhicule ferroviaire présentant un système de ventilation, la plateforme comprenant une partie haute, une partie basse et un escalier reliant la partie haute et la partie basse.The present invention relates to a railway vehicle platform having a ventilation system, the platform comprising an upper part, a lower part and a staircase connecting the upper part and the lower part.

Elle concerne également une voiture de véhicule ferroviaire associée.It also relates to an associated rail vehicle car.

Un système de ventilation peut comprendre, par exemple, un premier dispositif de soufflage en haut d'une paroi de la partie basse et un deuxième dispositif de soufflage en haut d'une paroi de la partie haute.A ventilation system may include, for example, a first blower device at the top of a wall of the lower part and a second blower device at the top of a wall of the upper part.

Ces deux dispositifs servent à la fois à la climatisation et au chauffage, c'est-à-dire que, pour chauffer, les deux dispositifs soufflent de l'air chaud et, pour refroidir, les deux dispositifs soufflent de l'air froid.These two devices are used for both air conditioning and heating, that is, for heating, both devices blow hot air, and for cooling, both devices blow cold air.

Cependant, l'air chaud a tendance à remonter par rapport à un air plus froid. Ainsi, dans le cas du chauffage, l'air chaud reste en hauteur dans chacune des parties de la plateforme et entre la partie haute et la partie basse.However, warm air tends to rise compared to colder air. Thus, in the case of heating, the hot air remains high in each part of the platform and between the upper part and the lower part.

Un fort gradient thermique se met alors en place entre le plafond et le sol, ce qui n'est pas confortable pour les passagers.A strong thermal gradient is then set up between the ceiling and the floor, which is not comfortable for the passengers.

JP 2001 199330 A décrit une voiture de véhicule ferroviaire comprenant un premier étage, un deuxième étage et une entrée, dans lequel un équipement de climatisation est agencé au-dessus de chaque entrée. JP 2001 199330 A describes a rail vehicle car comprising a first stage, a second stage and an entrance, in which air conditioning equipment is arranged above each entrance.

US 2 698 569 A décrit un système de climatisation pour des véhicules à deux étages et comprenant une entrée commune aux deux étages. Le système comprend un espace plénum au-dessus de l'entrée, une prise d'air et des moyens d'approvisionnement pour l'espace plénum et des moyens de distribution d'air différents pour les différents étages et approvisionnés par les moyens d'approvisionnement en air. US 2,698,569 A describes an air conditioning system for vehicles with two floors and comprising an entrance common to both floors. The system comprises a plenum space above the inlet, an air intake and supply means for the plenum space and different air distribution means for the different floors and supplied by the means of air supply.

L'invention a notamment pour but de remédier à cet inconvénient en fournissant un système de ventilation permettant une bonne répartition thermique dans la plateforme.The object of the invention is in particular to remedy this drawback by providing a ventilation system allowing good thermal distribution in the platform.

A cet effet, l'invention a notamment pour objet une plateforme de véhicule ferroviaire présentant un système de ventilation selon la revendication 1.To this end, the subject of the invention is in particular a railway vehicle platform having a ventilation system according to claim 1.

La plateforme de véhicule selon l'invention peut comporter en outre les caractéristiques des revendications 2 à 8, prises seules ou selon toutes les combinaisons techniquement possibles.The vehicle platform according to the invention may further include the characteristics of claims 2 to 8, taken alone or in any technically possible combination.

L'invention concerne également une voiture de véhicule ferroviaire selon la revendication 9.The invention also relates to a rail vehicle car according to claim 9.

La voiture selon l'invention peut comporter en outre les caractéristiques des revendications 10 et 11.The car according to the invention can also include the characteristics of claims 10 and 11.

L'invention sera mieux comprise à la lecture de la description qui va suivre, donnée uniquement à titre d'exemple et faite en se référant aux figures annexées parmi lesquelles :

  • les figures 1 et 2 sont respectivement des vues schématiques de face d'une partie haute et d'une partie basse d'une plateforme pourvue d'un système de ventilation selon un mode de réalisation de l'invention, et
  • les figures 3 et 4 sont des vues schématiques de haut et de côté de la plateforme pourvue du système de ventilation.

  • the figures 3 and 4 are schematic top and side views of the platform provided with the ventilation system.

Dans la présente description, les termes « vertical » et « horizontal » sont définis par rapport à un véhicule ferroviaire. Ainsi, un plan horizontal est sensiblement parallèle au plan de roulement du véhicule et la direction verticale est sensiblement perpendiculaire au plan de roulement. Par ailleurs, les termes « haut », référencé H, et « bas », référencé B, sont définis classiquement selon la direction verticale.In the present description, the terms “vertical” and “horizontal” are defined with respect to a railway vehicle. Thus, a horizontal plane is substantially parallel to the running plane of the vehicle and the vertical direction is substantially perpendicular to the running plane. Furthermore, the terms “top”, referenced H, and “bottom”, referenced B, are defined conventionally in the vertical direction.

Le terme « longitudinal » est défini par rapport à la direction dans laquelle s'étend un véhicule ferroviaire et correspondant à la direction de circulation du véhicule ferroviaire, et le terme « transversal » est défini selon une direction sensiblement perpendiculaire à la direction longitudinale et à la direction verticale.The term "longitudinal" is defined with respect to the direction in which a rail vehicle extends and corresponding to the direction of travel of the rail vehicle, and the term "transverse" is defined in a direction substantially perpendicular to the longitudinal direction and to the vertical direction.

Dans un mode de réalisation particulier, le système de ventilation comprend un sixième dispositif de soufflage B1B à proximité de la première porte 56. La première porte 56 est située du côté dans lequel débouche l'escalier 16.In a particular embodiment, the ventilation system comprises a sixth blower device B1B near the first door 56. The first door 56 is located on the side into which the staircase 16 opens.

Le sixième dispositif de soufflage B1B est situé à côté du premier dispositif de soufflage B1A sur la paroi avant 46 en s'éloignant de la première porte 56.The sixth blower B1B is located next to the first blower B1A on the front wall 46 away from the first door 56.

Le sixième dispositif de soufflage est agencé pour souffler de l'air en direction de la deuxième porte. L'air soufflé par le sixième dispositif de soufflage B1B est, par exemple, sensiblement transversal, horizontal et le long de la paroi avant 46.The sixth blower device is arranged to blow air towards the second door. The air blown by the sixth blower device B1B is, for example, substantially transverse, horizontal and along the front wall 46.

Le sixième dispositif de soufflage B1B est sensiblement vertical, c'est-à-dire qu'il débouche dans l'habitacle bas sous la forme d'une fente sensiblement verticale .L'air soufflé par les différents dispositifs de soufflage provient d'un groupe de climatisation adapté pour traiter, chauffer et/ou refroidir l'air. Le groupe de climatisation est alimenté par de l'air extérieur et de l'air recyclé provenant des parties hautes et basses, comme décrit ci-après.The sixth blowing device B1B is substantially vertical, that is to say that it opens into the low passenger compartment in the form of a substantially vertical slot. The air blown by the various blowing devices comes from a air conditioning unit suitable for treating, heating and / or cooling the air. The air conditioning unit is supplied with outside air and recirculated air from the upper and lower parts, as described below.

Le système de ventilation comprend de préférence un premier dispositif d'aspiration E1 d'air. Le premier dispositif d'aspiration E1 s'étend le long d'un côté de l'escalier 16 sur au moins 75% de la longueur de l'escalier, plus particulièrement ici sur le bas du côté gauche 64 de l'escalier.The ventilation system preferably comprises a first air suction device E1. The first suction device E1 extends along one side of the staircase 16 for at least 75% of the length of the staircase, more particularly here on the bottom of the left side 64 of the staircase.

Le premier dispositif d'aspiration E1 est en oblique par rapport à l'horizontale, plus particulièrement il est parallèle au sol 68 et/ou au plafond 66 de l'escalier 16.The first suction device E1 is oblique with respect to the horizontal, more particularly it is parallel to the floor 68 and / or to the ceiling 66 of the staircase 16.

L'air aspiré par le premier dispositif d'aspiration E1 est renvoyé au groupe de climatisation pour être traité.The air sucked in by the first suction device E1 is returned to the air conditioning unit for treatment.

Le premier dispositif d'aspiration est prévu pour aspirer entre 1 250 m3 et 1 550 m3 d'air par heure.The first suction device is designed to suck between 1250 m 3 and 1550 m 3 of air per hour.

Le système de ventilation comprend, en outre, au moins un deuxième dispositif d'aspiration d'air D1, F1. L'air aspiré par le deuxième dispositif d'aspiration d'air est refoulé dans des espaces aménagés du type toilettes, puis à l'extérieur. Un deuxième dispositif d'aspiration d'air D1, F1 est ici ménagé dans chaque porte ou à proximité de chaque porte 36, 62 permettant d'accéder aux espaces aménagés.The ventilation system further comprises at least one second air suction device D1, F1. The air sucked in by the second air suction device is returned to spaces fitted out such as toilets, then to the outside. A second air suction device D1, F1 is here provided in each door or near each door 36, 62 allowing access to the fitted spaces.

Chaque deuxième dispositif d'aspiration d'air est prévu pour aspirer entre 150 m3 et 250 m3 d'air par heure.Each second air suction device is designed to suck between 150 m 3 and 250 m 3 of air per hour.

Chaque dispositif d'aspiration et de soufflage est dissimulé grâce à un système de double paroi, le dispositif étant placé entre deux cloisons formant la paroi et soufflant ou aspirant de l'air grâce à une ou plusieurs ouvertures dans la cloison interne.Each suction and blowing device is concealed by means of a double wall system, the device being placed between two partitions forming the wall and blowing or sucking air through one or more openings in the internal partition.

L'air soufflé par chaque dispositif de soufflage est chaud ou froid par rapport à la température moyenne dans la plateforme. Préférentiellement, l'air soufflé par l'ensemble des dispositifs de soufflage a sensiblement la même température à un instant donné.The air blown by each blower device is hot or cold compared to the average temperature in the platform. Preferably, the air blown by all of the blowing devices has substantially the same temperature at a given time.

Les premier et deuxième dispositifs de soufflage B1A, B2A sont agencés pour que l'air soufflé entraîne la formation d'un rouleau de circulation 80 d'air devant chacune des portes 56, permettant de brasser l'air. Les rouleaux ont ici un axe vertical.The first and second blowing devices B1A, B2A are arranged so that the blown air causes the formation of an air circulation roller 80 in front of each of the doors 56, making it possible to stir the air. The rollers here have a vertical axis.

Dans le mode de réalisation correspondant, le premier dispositif de soufflage B1Aet le deuxième dispositif de soufflage B2A sont agencés pour former deux rouleaux d'air de sens de rotation opposé.In the corresponding embodiment, the first blowing device B1A and the second blowing device B2A are arranged to form two air rollers of opposite direction of rotation.

Les portes 56 sont susceptibles de présenter des défauts dans l'isolation. Les rouleaux de circulation permettent ainsi de mettre en place une zone tampon entre l'air de l'habitacle et l'air s'infiltrant depuis l'extérieur.The doors 56 are liable to have defects in the insulation. The circulation rollers thus make it possible to set up a buffer zone between the air in the passenger compartment and the air infiltrating from the outside.

De plus, le quatrième dispositif de soufflage A2 est agencé pour que l'air soufflé soit entraîné par l'air soufflé par le troisième dispositif de soufflage A1, de sorte à former un rouleau de circulation d'air 82 dans la partie haute 12. Le rouleau a un axe longitudinal. Cela permet notamment d'homogénéiser la température, plus particulièrement dans la partie haute 12.In addition, the fourth blower device A2 is arranged so that the blown air is entrained by the air blown by the third blower device A1, so as to form an air circulation roller 82 in the upper part 12. The roller has a longitudinal axis. This makes it possible in particular to homogenize the temperature, more particularly in the upper part 12.

Additionnellement, l'air soufflé par le cinquième dispositif d'aspiration C1, C2 circule le long du sol et permet une régulation thermique du sol. Plus particulièrement, lorsqu'il fait froid, le sol est également froid et est difficilement chauffé. Ainsi, le cinquième dispositif d'aspiration C1, C2 permet notamment de chauffer directement le sol en soufflant de l'air chaud.Additionally, the air blown by the fifth suction device C1, C2 circulates along the floor and allows thermal regulation of the floor. More particularly, when it is cold, the ground is also cold and is hardly heated. Thus, the fifth suction device C1, C2 makes it possible in particular to directly heat the ground by blowing hot air.

De plus, l'air est soufflé par les différents dispositifs de soufflage généralement le long de paroi(s). L'air circule plus loin que s'il est soufflé directement dans un volume libre, la circulation de l'air étant guidée par la paroi.In addition, the air is blown by the various blowing devices generally along the wall (s). The air circulates further than if it is blown directly into a free volume, the air circulation being guided by the wall.

Le premier dispositif d'aspiration E1 favorise également la circulation et le brassage d'air en aspirant l'air des parties haute et basse 12, 14 en direction de l'escalier 16.The first suction device E1 also promotes the circulation and mixing of air by sucking the air from the upper and lower parts 12, 14 towards the staircase 16.

Le système de ventilation favorise donc la circulation d'air, et ainsi la bonne répartition thermique dans la plateforme. Il est en outre efficace pour refroidir ou réchauffer la plateforme, en soufflant de l'air plus froid ou plus chaud que la température moyenne de la plateforme.The ventilation system therefore promotes air circulation, and thus good thermal distribution in the platform. It is also effective in cooling or heating the platform, blowing air colder or warmer than the average platform temperature.
