Description

« Système d'aération de l'habitacle d'un véhicule de transport en commun, et véhicule comprenant un tel système »  "Aeration system of the passenger compartment of a public transport vehicle, and a vehicle comprising such a system"
La présente invention concerne un système d'aération de l'habitacle d'un véhicule de transport en commun. Elle concerne également un véhicule terrestre de transport en commun, de type bus ou tram-bus, équipé d'un tel système d'aération. The present invention relates to a ventilation system of the passenger compartment of a public transport vehicle. It also relates to a ground public transport vehicle, bus or tram-bus type, equipped with such a ventilation system.
Le domaine de l'invention est le domaine des véhicules terrestres, en particulier des véhicules électriques, de transport en commun, de type bus, car ou tram-bus. The field of the invention is the field of land vehicles, in particular electric vehicles, public transport, bus, coach or tram-bus.
Etat de la technique State of the art
L'habitacle d'un véhicule de transport en commun, de type bus ou tram-bus, est prévu pour accueillir un nombre important de personnes. Par conséquent, l'habitacle d'un véhicule doit être de grande taille.  The interior of a public transport vehicle, bus or tram-bus, is intended to accommodate a large number of people. Therefore, the interior of a vehicle must be large.
Dans le même temps, le véhicule de transport en commun doit être équipé de systèmes pour répondre à des besoins divers au sein de l'habitacle, tels que le chauffage, l'éclairage, l'aération, etc. Ces systèmes doivent être dimensionnés de manière suffisamment grande en vue de répondre aux besoins associés à un habitacle de grandes dimensions.  At the same time, the transit vehicle must be equipped with systems to meet various needs within the cabin, such as heating, lighting, ventilation, etc. These systems must be dimensioned sufficiently large to meet the needs associated with a large passenger compartment.
En particulier, le système d'aération associé à l'habitacle d'un véhicule de transport en commun doit être dimensionné suffisamment grand pour répondre au besoin en aération dudit habitacle.  In particular, the ventilation system associated with the passenger compartment of a public transport vehicle must be sized sufficiently large to meet the need for ventilation of said passenger compartment.
Dans les certains véhicules actuels, les systèmes d'aération comprennent généralement un bloc d'aération, de grandes dimensions, déposé sur le toit du véhicule, et qui alimente un circuit d'aération parcourant l'habitacle. Un tel système d'aération est encombrant. De plus, un bloc d'aération encombrant posé sur le toit d'un véhicule vient dégrader son équilibre, augmenter sa consommation, du fait de la résistance à l'air que peut constituer un tel bloc, et limite la possibilité de circulation d'un tel véhicule sur certaines routes, du fait de la hauteur additionnelle qu'il présente. En outre, ces systèmes d'aération actuels sont gourmands en énergie.In certain current vehicles, the aeration systems generally comprise a large ventilation block, deposited on the roof of the vehicle, which feeds a ventilation circuit passing through the passenger compartment. Such a ventilation system is bulky. In addition, a bulky aeration block placed on the roof of a vehicle degrades its balance, increase its consumption, because of the resistance to air that can constitute such a block, and limits the possibility of circulation of such a vehicle on certain roads, because of the additional height it presents. In addition, these current aeration systems are energy hungry.
En outre, dans les véhicules actuels, les bouches d'aération sont situées à la verticale du bloc d'aération à l'extérieur. Ainsi, l'air est prélevé à l'extérieur par les bouches d'aération est soufflé dans l'habitacle au même endroit, ce qui ne permet pas une aération efficace. In addition, in current vehicles, the air vents are located vertically from the vent block to the outside. Thus, the air is taken outside by the air vents is blown into the cabin at the same place, which does not allow effective ventilation.
Un but de la présente invention est de remédier à ces inconvénients.An object of the present invention is to overcome these disadvantages.
Un autre but de l'invention est de proposer un système d'aération pour véhicule de transport en commun moins volumineux et apportant moins de dégradations aux performances du véhicule en termes de tenue de route, de consommation et de hauteur. Another object of the invention is to provide a ventilation system for public transport vehicle less bulky and providing less damage to the performance of the vehicle in terms of handling, consumption and height.
Il est aussi un autre but de l'invention de proposer un système d'aération moins gourmand en énergie que les systèmes actuels, pour un taux d'aération donné.  It is also another object of the invention to provide a ventilation system that is less energy intensive than current systems, for a given aeration rate.
Encore un autre but de l'invention est de proposer un système d'aération permettant une meilleure répartition de l'air dans l'habitacle du véhicule.  Yet another object of the invention is to provide an aeration system for a better distribution of air in the passenger compartment of the vehicle.
Exposé de l'invention Presentation of the invention
L'invention permet d'atteindre au moins l'un de ces buts par un système d'aération de l'habitacle d'un véhicule de transport en commun comprenant :  The invention makes it possible to achieve at least one of these aims by a ventilation system of the passenger compartment of a public transport vehicle comprising:
- plusieurs ouvertures de captation de l'air extérieur, distribuées sur une paroi supérieure dudit véhicule,  - several openings for capturing the outside air, distributed on an upper wall of said vehicle,
- plusieurs ouvertures d'introduction d'air dans l'habitacle dudit véhicule, et  several openings for introducing air into the passenger compartment of said vehicle, and
- au moins un circuit de distribution d'air reliant lesdites ouvertures entre-elles.  at least one air distribution circuit connecting said openings to one another.
Ainsi, le système selon l'invention propose de prévoir plusieurs ouvertures de captation d'air et plusieurs ouvertures d'introduction d'air dans l'habitacle. Par conséquent, il n'est pas nécessaire de prévoir un ou plusieurs bloc(s) d'aération encombrant, comme dans les véhicules actuels. Par conséquent, les performances du véhicule de transport en commun, en termes de tenue de route, de consommation et de hauteur maximale, sont moins, voire pas du tout, dégradées avec le système d'aération selon l'invention. Thus, the system according to the invention proposes to provide several air intake openings and several air introduction openings in the passenger compartment. Therefore, it is not necessary to provide one or more bulky aeration block (s), as in current vehicles. As a result, the performance of the transit vehicle, in terms of handling, fuel consumption and maximum height, is less, if at all, degraded with the aeration system according to the invention.
De plus, le système comporte plusieurs ouvertures de captation d'air prévue sur la paroi supérieure du véhicule pour capter l'air extérieur qui est ensuite distribué dans l'habitacle avec au moins un circuit de distribution. Par conséquent, le circuit de distribution reliant une ouverture de captation à une ouverture d'introduction, présente une longueur plus faible, comparé aux systèmes d'aération actuels. Ainsi, le système d'aération selon l'invention est moins gourmand en énergie, et présente moins de pertes de charge, tout en réalisant une meilleure répartition de l'air dans l'habitacle du véhicule.  In addition, the system comprises a plurality of air intake openings provided on the upper wall of the vehicle for capturing the outside air which is then distributed in the passenger compartment with at least one distribution circuit. Therefore, the distribution circuit connecting a pick-up opening to an introductory opening, has a shorter length, compared to current aeration systems. Thus, the ventilation system according to the invention is less energy-intensive, and has less pressure losses, while achieving a better distribution of air in the passenger compartment of the vehicle.
Dans une version particulièrement avantageuse du système selon l'invention, au moins une ouverture de captation d'air peut être munie d'au moins un dispositif d'entraînement de l'air extérieur vers un circuit de distribution, tel qu'un ventilateur.  In a particularly advantageous version of the system according to the invention, at least one air intake opening may be provided with at least one device for driving the outside air to a distribution circuit, such as a fan.
Ainsi, l'air extérieur est mis en circulation forcée dans le circuit de distribution, ce qui permet d'augmenter le taux d'aération proposé par le système selon l'invention.  Thus, the outside air is forced into the distribution circuit, which makes it possible to increase the aeration rate proposed by the system according to the invention.
En outre, la vitesse de rotation du ventilateur peut être ajustable de sorte que le taux d'aération, et en particulier le débit d'air, peut être ajusté.  In addition, the rotational speed of the fan may be adjustable so that the aeration rate, and in particular the air flow, can be adjusted.
Dans un mode de réalisation préféré, mais nullement limitatif, au moins une ouverture de captation d'air peut être munie de deux dispositifs d'entraînement de l'air extérieur, positionnés en tête-bêche, de sorte à renvoyer l'air extérieur capté dans deux directions sensiblement opposées vers deux circuits de distribution correspondants. In a preferred embodiment, but in no way limiting, at least one air intake opening may be provided with two external air entrainment devices, positioned head-to-tail, so as to return the outside air captured. in two substantially opposite directions to two corresponding distribution circuits.
Cela permet d'augmenter encore plus le débit de l'air fourni par le système selon l'invention, sans augmenter le nombre d'ouvertures de captation. Cela permet aussi d'augmenter la possibilité d'ajustement de l'aération réalisé par le système selon l'invention, en termes de débit et de zones. Par exemple, il est ainsi possible d'ajuster l'aération réalisée dans une zone indépendamment des autres zones. En outre, au moins un, en particulier chaque, dispositif d'entraînement d'air peut être associé à un circuit de distribution, indépendant des autres circuits de distribution. This makes it possible to further increase the flow rate of the air supplied by the system according to the invention without increasing the number of capture openings. This also makes it possible to increase the possibility of adjusting the ventilation achieved by the system according to the invention, in terms of flow rate and zones. For example, it is possible to adjust the aeration performed in one zone independently of the other zones. In addition, at least one, in particular each, air entrainment device can be associated with a distribution circuit, independent of other distribution circuits.
En particulier, lorsqu'une ouverture de captation comporte deux dispositifs d'entraînement positionnés en tête-bêche, chacun desdits dispositifs d'entraînement peut être associé à un circuit de distribution indépendant du circuit de distribution associé à l'autre desdits dispositifs d'entraînement. Avantageusement, au moins une ouverture de captation d'air peut être munie d'un dispositif de traitement d'air.  In particular, when a pickup opening comprises two drive devices positioned upside down, each of said drive devices can be associated with a distribution circuit independent of the distribution circuit associated with the other of said drive devices. . Advantageously, at least one air intake opening may be provided with an air treatment device.
Un dispositif de traitement d'air peut comprendre un climatiseur ou une pompe à chaleur, et plus généralement tout dispositif modifiant la température de l'air extérieur capté.  An air treatment device may comprise an air conditioner or a heat pump, and more generally any device modifying the temperature of the outside air captured.
Alternativement ou en plus, un dispositif de traitement d'air peut comprendre un moyen pour filtrer l'air.  Alternatively or additionally, an air handler may include means for filtering air.
Avantageusement, au moins une ouverture de captation peut être connectée à au moins un, en particulier plusieurs, circuit(s) de distribution se prolongeant dans la direction longitudinale du véhicule. Advantageously, at least one pick-up opening may be connected to at least one, in particular several, distribution circuit (s) extending in the longitudinal direction of the vehicle.
Dans le cas où une ouverture de captation comporte deux dispositifs d'entraînement positionnés en tête-bêche, chacun desdits dispositifs d'entraînement peut être associé à un circuit de distribution se prolongeant dans la direction longitudinale du véhicule.  In the case where a pickup opening comprises two drive devices positioned head to tail, each of said drive devices can be associated with a distribution circuit extending in the longitudinal direction of the vehicle.
Cela permet d'augmenter l'efficacité du système d'aération selon l'invention, car les pertes de charges sont diminuées dans le cas de circuits longitudinaux.  This makes it possible to increase the efficiency of the ventilation system according to the invention, since the pressure drops are reduced in the case of longitudinal circuits.
Avantageusement, au moins une ouverture de captation peut être connectée à deux circuits de distribution se prolongeant dans la direction longitudinale du véhicule, de manière sensiblement parallèle entre eux. Advantageously, at least one capture opening may be connected to two distribution circuits extending in the longitudinal direction of the vehicle, substantially parallel to each other.
