Description
Domaine technique de l’inventionTechnical field of the invention
L’invention concerne les véhicules comprenant une installation de chauffage et/ou climatisation alimentant en air traité leur habitacle, et plus précisément le filtrage de l’air alimentant une telle installation.The invention relates to vehicles comprising a heating and/or air conditioning installation supplying their passenger compartment with treated air, and more specifically the filtering of the air supplying such an installation.
Etat de la techniqueState of the art
Certains véhicules, éventuellement de type automobile, comprennent au moins un habitacle alimenté en air traité par une installation de chauffage et/ou climatisation alimentée en air extérieur et en air recirculé issu de l’habitacle selon des proportions réglables.Certain vehicles, possibly of the automobile type, comprise at least one passenger compartment supplied with air treated by a heating and/or air conditioning installation supplied with outside air and with recirculated air from the passenger compartment according to adjustable proportions.
Dans ce type d’installation (de chauffage et/ou climatisation) on réalise une filtration d’une partie au moins de l’air qui alimente les éléments assurant le traitement de l’air avant qu’il n’alimente l’habitacle afin de filtrer certains polluants.In this type of installation (for heating and/or air conditioning) at least part of the air is filtered which supplies the elements ensuring the treatment of the air before it supplies the passenger compartment in order to filter certain pollutants.
On entend ici par « polluant » des poussières (de tailles importantes), des particules fines (par exemple de type PM10, PM2,5 ou PM1), un gaz inodore (par exemple de l’oxyde d’azote (ou NOx) ou du monoxyde de carbone (ou CO)), un gaz odorant (par exemple un gaz carboné de type CxHy), du gaz carbonique (CO2), des composés organiques volatils (ou COVs), ou un allergène extérieur produit par des végétaux (comme par exemple du pollen).Here, “pollutant” means dust (of large size), fine particles (for example of the PM10, PM2.5 or PM1 type), an odorless gas (for example nitrogen oxide (or NOx) or carbon monoxide (or CO)), an odorous gas (for example a carbonaceous gas of the CxHy type), carbon dioxide (CO2), volatile organic compounds (or VOCs), or an external allergen produced by plants (such as for example pollen).
Pour réaliser la filtration précitée, on peut installer un filtre à air soit sur le conduit d’alimentation qui alimente l’installation en air extérieur en amont du pulseur, soit en aval du pulseur.To achieve the aforementioned filtration, an air filter can be installed either on the supply duct which supplies the installation with outside air upstream of the pulser, or downstream of the pulser.
La première alternative présente l’avantage de protéger le pulseur de certains polluants contenus dans l’air extérieur tout en permettant l’utilisation d’un filtre à air de grandes dimensions, mais son inconvénient principal réside dans le fait qu’elle ne permet pas de filtrer l’air recirculé.The first alternative has the advantage of protecting the blower from certain pollutants contained in the outside air while allowing the use of a large air filter, but its main drawback lies in the fact that it does not allow to filter the recirculated air.
La seconde alternative présente l’avantage de filtrer non seulement l’air extérieur mais aussi l’air recirculé, cependant elle présente plusieurs inconvénients parmi lesquels l’impossibilité de protéger le pulseur de certains polluants contenus dans l’air extérieur et dans l’air recirculé, l’impossibilité d’utiliser un filtre à air de grandes dimensions pour limiter l’encombrement et la perte de charge aéraulique (ce qui interdit la filtration de type dit à haute efficacité (ou HEPA)), et un encrassement rapide du fait de la filtration de l’air extérieur qui contient les particules ayant les dimensions les plus importantes.The second alternative has the advantage of filtering not only the outside air but also the recirculated air, however it has several drawbacks including the impossibility of protecting the blower from certain pollutants contained in the outside air and in the air. recirculated, the impossibility of using a large air filter to limit the size and the aeraulic pressure drop (which prohibits so-called high-efficiency (or HEPA) type filtration), and rapid clogging due to the filtration of the outside air which contains the particles having the largest dimensions.
Il est rappelé qu’une filtration à haute efficacité (ou HEPA) permet de filtrer en un passage au moins 99,97 % des particules ayant un diamètre supérieur ou égal à 0,3 µm.It is recalled that high efficiency filtration (or HEPA) makes it possible to filter in one pass at least 99.97% of particles with a diameter greater than or equal to 0.3 µm.
Il serait certes possible d’installer un premier filtre à air sur le premier conduit d’alimentation qui alimente l’installation en air extérieur (en amont du pulseur), et un second filtre à air sur le second conduit d’alimentation qui alimente l’installation en air recirculé (en amont du pulseur). Mais la section de ce second conduit d’alimentation étant relativement petite, le second filtre à air induirait une perte de charge aéraulique trop importante. Par ailleurs, il serait très difficile d’obtenir une étanchéité de qualité indispensable à l’obtention d’une filtration HEPA, en raison de cette petite section du second conduit d’alimentation. En outre, l’accès au second conduit d’alimentation étant relativement difficile, le remplacement du second filtre à air serait difficile.It would certainly be possible to install a first air filter on the first supply duct which supplies the installation with outside air (upstream of the blower), and a second air filter on the second supply duct which supplies the recirculated air installation (upstream of the blower). But the section of this second supply duct being relatively small, the second air filter would induce too great an aeraulic pressure drop. Moreover, it would be very difficult to obtain the quality sealing essential for obtaining HEPA filtration, because of this small section of the second supply duct. In addition, access to the second supply duct being relatively difficult, the replacement of the second air filter would be difficult.
L’invention a donc notamment pour but d’améliorer la situation.The aim of the invention is therefore in particular to improve the situation.
Présentation de l’inventionPresentation of the invention
Elle propose notamment à cet effet un dispositif de rangement, d’une part, propre à équiper un véhicule comprenant un habitacle alimenté en air traité par une installation de chauffage et/ou climatisation comprenant un conduit d’alimentation recevant de l’air recirculé issu de l’habitacle, et, d’autre part, comprenant un boîtier délimitant un espace de rangement destiné à être accessible depuis l’habitacle.It proposes in particular for this purpose a storage device, on the one hand, suitable for equipping a vehicle comprising a passenger compartment supplied with air treated by a heating and/or air conditioning installation comprising a supply duct receiving recirculated air from of the passenger compartment, and, on the other hand, comprising a box defining a storage space intended to be accessible from the passenger compartment.
Ce dispositif de rangement se caractérise par le fait que son boîtier délimite aussi un espace auxiliaire, d’une part, comprenant une sortie d’air destinée à être couplée au conduit d’alimentation et une entrée d’air propre à recevoir l’air recirculé issu de l’habitacle, et, d’autre part, logeant, entre les entrée d’air et sortie d’air, un filtre à air propre à effectuer un filtrage de l’air recirculé en amont du conduit d’alimentation.This storage device is characterized in that its housing also delimits an auxiliary space, on the one hand, comprising an air outlet intended to be coupled to the supply duct and an air inlet suitable for receiving air recirculated from the passenger compartment, and, on the other hand, housing, between the air inlet and air outlet, an air filter suitable for filtering the recirculated air upstream of the supply duct.
Grâce à l’invention, on peut désormais utiliser un filtre à air de grandes dimensions pour filtrer l’air recirculé car la place disponible dans le boîtier est importante, ce qui permet avantageusement d’effectuer une filtration de type HEPA sur cet air recirculé tout en évitant une forte perte de charge aéraulique et un encrassement rapide de ce filtre à air.Thanks to the invention, it is now possible to use a large air filter to filter the recirculated air because the space available in the housing is large, which advantageously makes it possible to carry out a HEPA type filtration on this recirculated air while avoiding a high air pressure drop and rapid clogging of this air filter.
Le dispositif de rangement selon l’invention peut comporter d’autres caractéristiques qui peuvent être prises séparément ou en combinaison, et notamment :The storage device according to the invention may comprise other characteristics which may be taken separately or in combination, and in particular:
- l’entrée d’air peut être définie dans le boîtier et peut être destinée à communiquer avec l’habitacle ;- the air inlet may be defined in the housing and may be intended to communicate with the passenger compartment;
- en présence de la première option, il peut comprendre une grille solidarisée au boîtier au niveau de l’entrée d’air ;- in the presence of the first option, it may include a grid secured to the box at the level of the air inlet;
- il peut comprendre un conduit auxiliaire comportant une première extrémité solidarisée fixement et de façon étanche au boîtier au niveau de la sortie d’air, et une seconde extrémité opposée à cette première extrémité et destinée à être solidarisée fixement et de façon étanche au conduit d’alimentation ;- it may comprise an auxiliary duct comprising a first end secured fixedly and sealingly to the casing at the level of the air outlet, and a second end opposite this first end and intended to be secured fixedly and sealingly to the duct 'feed ;
- l’espace auxiliaire peut être situé au-dessous ou au-dessus de l’espace de rangement. En variante, l’espace auxiliaire peut être situé à droite ou à gauche de l’espace de rangement, et peut loger le filtre à air dans une position verticale ;- the auxiliary space can be located below or above the storage space. Alternatively, the auxiliary space can be located to the right or left of the storage space, and can accommodate the air filter in a vertical position;
- l’espace auxiliaire peut être séparé de l’espace de rangement par une cloison comportant un volet propre à prendre au moins une position fermée dans laquelle il masque le filtre à air et une position ouverte dans laquelle il permet un accès au filtre à air depuis l’espace de rangement. En variante, le boîtier peut comprendre une ouverture à accès contrôlé par un volet situé à l’interface avec l’habitacle et propre à prendre au moins une position fermée dans laquelle il masque le filtre à air et une position ouverte dans laquelle il permet un accès au filtre à air depuis l’habitacle ;- the auxiliary space can be separated from the storage space by a partition comprising a flap suitable for assuming at least one closed position in which it conceals the air filter and an open position in which it allows access to the air filter from the storage space. As a variant, the housing may comprise an opening with access controlled by a flap located at the interface with the passenger compartment and able to assume at least one closed position in which it hides the air filter and an open position in which it allows a access to the air filter from the passenger compartment;
- le filtre à air peut être de type dit à haute efficacité ;- the air filter can be of the so-called high-efficiency type;
- l’espace de rangement peut constituer une boîte à gants.- the storage space can constitute a glove box.
L’invention propose également un véhicule, éventuellement de type automobile, et comprenant, d’une part, un habitacle alimenté en air traité par une installation de chauffage et/ou climatisation comprenant un conduit d’alimentation recevant de l’air recirculé issu de l’habitacle, et, d’autre part, un dispositif de rangement du type de celui présenté ci-avant, accessible depuis l’habitacle et couplé au conduit d’alimentation.The invention also proposes a vehicle, optionally of the automobile type, and comprising, on the one hand, a passenger compartment supplied with air treated by a heating and/or air conditioning installation comprising a supply duct receiving recirculated air from the passenger compartment, and, on the other hand, a storage device of the type presented above, accessible from the passenger compartment and coupled to the supply conduit.
