Installation de chauffage-climatisation de l'habitacle d'un véhicule
L'invention concerne une installation de chauffage-climatisation de l'habitacle d'un véhicule, comprenant des moyens de traitement d'air pour produire de l'air traité - soit chaud, soit climatisé - et des conduits pour acheminer cet air traité vers des bouches de distribution réparties dans l'habitacle.Installation of heating and air conditioning in the passenger compartment of a vehicle
The invention relates to a heating and air conditioning installation for the passenger compartment of a vehicle, comprising air treatment means for producing treated air - either hot or air-conditioned - and ducts for conveying this treated air to distribution outlets distributed in the passenger compartment.
Dans une installation de ce type, les moyens de traitement d'air comprennent généralement un pulseur alimenté en air extérieur et/ou en air recirculé et propre à pulser cet air au travers d'un évaporateur et/ou d'un radiateur de chauffage pour produire de l'air traité. Habituellement, les moyens de traitement de l'air comprennent un dispositif unique situé à l'avant du véhicule, soit dans le compartiment moteur, soit sous la planche de bord.In an installation of this type, the air treatment means generally comprise a blower supplied with external air and / or recirculated air and capable of blowing this air through an evaporator and / or a heating radiator for produce treated air. Usually, the air treatment means comprise a single device located at the front of the vehicle, either in the engine compartment or under the dashboard.
Cet air traité circule dans des conduits rapportés reliés d'une part aux moyens de traitement de l'air et d'autre part aux bouches de distribution de l'air traité.This treated air circulates in attached conduits connected on the one hand to the air treatment means and on the other hand to the distribution outlets of the treated air.
Ces conduits rapportés sont disposés le plus souvent au niveau de la planche de bord pour alimenter des bouches de distribution situées dans la partie avant de l'habitacle.These added conduits are most often arranged at the dashboard to supply distribution outlets located in the front part of the passenger compartment.
Dans certains types de véhicules on trouve aussi des conduits rapportés qui alimentent des bouches de distribution situées à l'arrière du véhicule, par exemple en passant entre les sièges avant.In certain types of vehicles there are also added conduits which supply distribution outlets located at the rear of the vehicle, for example passing between the front seats.
Ce type d'installation ne présentait pas d'inconvénients majeurs jusqu'à l'apparition de véhicules de grand volume hitable, appelés "monocorps" ou "monospaces", qui comportent au moins deux rangées de sièges. This type of installation did not have any major drawbacks until the appearance of vehicles of large, hitable volume, called "monocorps" or "minivans", which have at least two rows of seats.
Ces véhicules d'un type nouveau nécessitent des moyens puissants de traitement d'air, un grand nombre de bouches reparties dans l'habitacle ainsi que des conduits rapportés de grande longueur, difficiles à installer, encombrants, et présentant des pertes thermiques importantes.These vehicles of a new type require powerful means of air treatment, a large number of vents distributed in the passenger compartment as well as added ducts of great length, difficult to install, bulky, and having significant heat losses.
L'invention a notamment pour but de surmonter les inconvé lents précités.The object of the invention is in particular to overcome the aforementioned slow drawbacks.
Elle propose à cet effet une installation du type défini en introduction, dans laquelle les conduits servant à acheminer l'air traité comprennent des éléments creux faisant partie de l'ossature du véhicule, ces éléments creux étant reliés, d'une part aux moyens de traitement d'air, et d'autre part aux différentes bouches de distribution placées dans l'habiracle.To this end, it proposes an installation of the type defined in the introduction, in which the conduits serving to convey the treated air comprise hollow elements forming part of the framework of the vehicle, these hollow elements being connected, on the one hand to the means of air treatment, and on the other hand to the various distribution outlets placed in the cockpit.
Par "ossature", on entend ici désigner l'ensemble de la structure métallique du véhicule comprenant essentiellement le châssis et les montants.The term "framework" is understood here to denote the entire metal structure of the vehicle essentially comprising the chassis and the uprights.
Ainsi, conformément à l'invention, l'air traité est acheminé vers les bouches de distribution, non pas par des conduits reportés comme antérieurement, mais par des éléments creux et rigides faisant partie de l'ossature du véhicule.Thus, in accordance with the invention, the treated air is conveyed to the distribution outlets, not by deferred conduits as before, but by hollow and rigid elements forming part of the framework of the vehicle.
Ces éléments creux d'ossature remplissent donc une double fonction, à savoir leur fonction habituelle de renforcement du véhicule, et une fonction supplémentaire d'acheminement de l'air traité.These hollow framework elements therefore fulfill a double function, namely their usual function of reinforcing the vehicle, and an additional function of conveying the treated air.
I1 n'est alors plus nécessaire de prévoir des conduits rapportés pour alimenter les bouches de distribution situées dans l'habitacle. I1 is then no longer necessary to provide added conduits to supply the distribution outlets located in the passenger compartment.
Selon une autre caractéristique de l'invention, les éléments deux sont choisis parmi des longerons, des traverses et des montants de l'ossature du véhicule. According to another characteristic of the invention, the two elements are chosen from longitudinal members, cross members and uprights of the vehicle frame.
- Maçon avantageuse, ces éléments creux comprennent deux na-erons situés au niveau du plancher du véhicule, au moins
r montant relié à chaque longeron, ainsi qu'au moins une traverse reliant les deux longerons.- Advantageous mason, these hollow elements include two na-erons located at the level of the vehicle floor, at least
r amount connected to each beam, as well as at least one cross connecting the two beams.
A titre d'exemple, les éléments creux peuvent comprendre deux longerons situés au niveau du plancher, deux montants reliés a chaque longeron et deux traverses reliant les deux longerons, une traverse étant placée à l'avant du véhicule et l'autre à l'arrière.For example, the hollow elements may include two side members located at floor level, two uprights connected to each side member and two cross members connecting the two side members, one cross member being placed at the front of the vehicle and the other at the back.
De façon avantageuse, une traverse est disposée au niveau de la planche de bord. Celle-ci permet d'envoyer de l'air traité vers des bouches de distribution situées au niveau de la planche de bord et orientées soit vers le pare-brise, soit vers l'intérieur de l'habitacle.Advantageously, a cross member is disposed at the level of the dashboard. This allows the treated air to be sent to distribution outlets located at the dashboard and oriented either towards the windshield or towards the interior of the passenger compartment.
Selon une autre caractéristique avantageuse de l'invention, les moyens de traitement d'air sont placés à proximité d'un élément creux de l'ossature du véhicule, avec lequel ils communiquent.According to another advantageous characteristic of the invention, the air treatment means are placed near a hollow element of the vehicle frame, with which they communicate.
Dans une forme de réalisation préférée de l'invention, les moyens de traitement d'air sont placés à proximité d'un longeron de l'ossature et communiquent avec celui-ci.In a preferred embodiment of the invention, the air treatment means are placed close to and communicate with a spar of the frame.
De façon avantageuse, les moyens de traitement d'air sont disposés sous le plancher du véhicule.Advantageously, the air treatment means are arranged under the floor of the vehicle.
tien entendu, il serait également concevable de les loger dans un endroit traditionnel, ctest-à-dire soit dans le compartiment moteur antérieur, soit sous la planche de bord.Of course, it would also be conceivable to house them in a traditional place, that is to say either in the front engine compartment, or under the dashboard.
Dâns la description qui suit, faite seulement à titre d'exemple, on se réfère au dessin annexé, sur lequel - la figure 1 est une vue latérale schématique, avec arrache ',ent partiel, d'un véhicule équipé d'une installation de cnauffage-climatisation selon l'invention; et - la figure 2 est une vue schématique de dessus, avec arrachement partiel, du véhicule de la figure 1. In the following description, given only by way of example, reference is made to the appended drawing, in which - FIG. 1 is a schematic side view, with parts broken away, partially, of a vehicle fitted with a air conditioning according to the invention; and - Figure 2 is a schematic top view, partially broken away, of the vehicle of Figure 1.
On â représenté aux figures 1 et 2 un véhicule automobile V, j type "monocorps" ou "monospace", comprenant un habitacle I de grand volume. Le véhicule possède un pare-brise P situé siblement dans le prolongement du capot moteur C.There is shown in Figures 1 and 2 a motor vehicle V, j type "unibody" or "minivan", comprising a passenger compartment I of large volume. The vehicle has a windshield P located only in the extension of the engine hood C.
Le véhicule V est équipé d'une installation de chauffage-climatisation désignée dans son ensemble par la référence 10.Vehicle V is fitted with a heating and air conditioning installation designated as a whole by the reference 10.
L'installation 10 comprend un dispositif de traitement d'air 12 situé sous le plancher S du véhicule et du côté droit de ce dernier. Le dispositif de traitement 10 est alimenté en air extérieur et/ou en air recirculé (provenant de l'habitacle H) par une bouche d'entrée 14. Le dispositif 12 comprend, de façon en soi connue, un pulseur (non représenté) propre à pulser l'air provenant de la bouche d'entrée 14 au travers d'un évaporateur (non représenté) et/ou d'un radiateur de chauffage (non représenté) pour produire de l'air traité, c'est-à-dire de l'air chaud ou de l'air climatisé.The installation 10 comprises an air treatment device 12 located under the floor S of the vehicle and on the right side of the latter. The treatment device 10 is supplied with outside air and / or recirculated air (coming from the passenger compartment H) by an inlet mouth 14. The device 12 comprises, in a manner known per se, a clean blower (not shown) pulsating the air coming from the inlet mouth 14 through an evaporator (not shown) and / or a heating radiator (not shown) to produce treated air, that is to say say hot air or air conditioning.
En outre, le dispositif 12 comprend une sortie d'air 16 qui débouche dans un longeron creux 18 s'étendant au niveau du plancher du véhicule et du côté droit de celui-ci. Le longeron creux 18 est un élément creux faisant partie de i'ossature du véhicule, cette dernière comprenant en outre un autre longeron 18 analogue, situé du côté gauche.In addition, the device 12 includes an air outlet 16 which opens into a hollow spar 18 extending at the level of the vehicle floor and on the right side thereof. The hollow spar 18 is a hollow member forming part of the vehicle frame, the latter further comprising another similar spar 18, located on the left side.
;es deux longerons 18 communiquent entre eux par une traverse horizontale 20 située à l'arrière du véhicule et sensiblement au niveau du plancher et par une traverse horizontale incurvée 22 située vers l'avant, sensiblement au niveau de la planche de bord B. ; es two side members 18 communicate with each other by a horizontal cross member 20 located at the rear of the vehicle and substantially at the floor and by a curved horizontal cross member 22 located forward, substantially at the dashboard B.
L'air traité provenant du dispositif 12 peut ainsi circuler fi l'intérieur des deux longerons 18 et des deux traverses 20 et 22. The treated air coming from the device 12 can thus circulate inside the two beams 18 and the two crosspieces 20 and 22.
Chacun des longerons 18 communique avec deux montants creux 24 et 26 qui s'étendent sensiblement verticalement au niveau des portières (non représentées) du véhicule V.Each of the side members 18 communicates with two hollow uprights 24 and 26 which extend substantially vertically at the doors (not shown) of the vehicle V.
À leur extrémité supérieure, les montants 24 et 26 communi quent avec un longeron 28 situé au niveau du pavillon du véhicule. At their upper end, the uprights 24 and 26 communicate with a beam 28 located at the level of the vehicle roof.
Les deux longerons 18, les deux traverses 20 et 22, les montants 24 et 26, ainsi que les deux longerons 28, constituent les principaux éléments creux d'une ossature et sont propres à être parcourus par l'air traité provenant du dispositif 12. Cet air traité est ensuite envoyé dans l'habitacle H par l'intermédiaire de bouches de distribution placées en des endroits choisis.The two longitudinal members 18, the two cross members 20 and 22, the uprights 24 and 26, as well as the two longitudinal members 28, constitute the main hollow elements of a framework and are suitable for being traversed by the treated air coming from the device 12. This treated air is then sent into the passenger compartment H via distribution outlets placed in selected locations.
Ainsi, les montants 24 et 26 sont munis respectivement de bouches 30 et 32.Thus, the uprights 24 and 26 are provided with mouths 30 and 32 respectively.
De plus, la traverse creuse 22 est munie d'une bouche centrale 34 et de deux bouches latérales symétriques 36 placées au niveau de la planche de bord B et propre à envoyer de l'air traité vers l'intérieur de l'habitacle H.In addition, the hollow cross member 22 is provided with a central mouth 34 and two symmetrical lateral mouths 36 placed at the level of the dashboard B and suitable for sending treated air into the interior of the passenger compartment H.
Par ailleurs, la traverse 22 est munie de deux bouches 38 symétriques orientées vers l'avant du véhicule et propres à envoyer de l'air traité en direction du pare-brise P pour assurer son dégivrage ou son désembuage.Furthermore, the cross member 22 is provided with two symmetrical mouths 38 oriented towards the front of the vehicle and capable of sending treated air towards the windshield P to ensure its defrosting or demisting.
Bien entendu, il est possible de prévoir d'autres bouches de distribution en des endroits convenablement choisis des eléments creux faisant partie de l'ossature.Of course, it is possible to provide other distribution outlets in suitably chosen locations of the hollow elements forming part of the framework.
Ainsi, les éléments creux de l'ossature remplissent non seulement leur fonction habituelle de rigidification du véhicule, mais en outre une fonction supplémentaire d'acheminement de l'air traité à distribuer dans l'habitacle. Thus, the hollow elements of the frame not only fulfill their usual function of stiffening the vehicle, but also an additional function of conveying the treated air to be distributed in the passenger compartment.
De ce fait, il n'est plus nécessaire de prévoir de conduits rapportés comme dans la technique antérieure.Therefore, it is no longer necessary to provide attached conduits as in the prior art.
On comprendra que les éléments creux de l'ossature peuvent être munis de cloisons transversales pour empecher que le flux d'air traité ne parvienne dans certains éléments de l'ossature, par exemple dans les longerons 28 situés au niveau du pavillon.It will be understood that the hollow elements of the frame can be provided with transverse partitions to prevent the flow of treated air from reaching certain elements of the frame, for example in the side members 28 located at the level of the roof.
Les bouches de distribution sont avantageusement munies chacune d'une grille et d'au moins un organe pour régler le débit et l'orientation du flux d'air quittant la grille.The distribution outlets are advantageously each provided with a grid and at least one member for adjusting the flow rate and the orientation of the air flow leaving the grid.
Bien que, dans l'exemple représenté, le dispositif de traitement 12 soit placé sous le plancher du véhicule, il est possible de prévoir un autre lieu d'implantation.Although, in the example shown, the treatment device 12 is placed under the vehicle floor, it is possible to provide another location.
Il serait envisageable, par exemple, de placer le dispositif de traitement 12 dans le compartiment moteur ou sous la planche de bord de manière à se situer à proximité de la traverse 22.It would be possible, for example, to place the treatment device 12 in the engine compartment or under the dashboard so as to be located near the cross-member 22.
L'installation de chauffage-climatisation de l'invention trouve une application particulière aux véhicules du type monocorps11 ou "monospace", mais est utilisable pour d'autres types de véhicules. The heating-air conditioning installation of the invention finds particular application to vehicles of the monocorps11 or "minivan" type, but can be used for other types of vehicles.
