Description

DISPOSITIF DE GENERATION D'UN FLUX D'AIR  DEVICE FOR GENERATING AN AIR FLOW
La présente invention concerne un dispositif de génération d'un flux d'air, notamment pour un dispositif de chauffage, ventilation et/ou climatisation d'un véhicule automobile. The present invention relates to a device for generating an air flow, in particular for a heating, ventilation and / or air conditioning device of a motor vehicle.
Un véhicule automobile comporte un habitacle dans lequel débouche de l'air issu classiquement d'un dispositif de chauffage, ventilation et/ou climatisation.  A motor vehicle has a passenger compartment into which the air typically comes from a heating, ventilation and / or air conditioning device.
Le véhicule comporte notamment une ou plusieurs buses de dégivrage situées à proximité du pare-brise, des aérateurs situés au niveau de la planche de bord et destinés à délivrer de l'air au conducteur et au passager, et des buses situées au niveau des pieds du conducteur et du passager (buses de pieds).  The vehicle includes in particular one or more deicing nozzles located near the windshield, aerators located at the dashboard and intended to deliver air to the driver and the passenger, and nozzles located at the level of the feet driver and passenger (foot nozzles).
Le dispositif de chauffage, ventilation et/ou climatisation, également appelé HVAC (pour Heating, Ventilation and Air-Conditioning, en anglais) peut être alimenté soit en air extérieur au véhicule (également appelé air neuf), soit en air de recyclage, c'est-à-dire issu de l'habitacle du véhicule.  The heating, ventilation and / or air conditioning device, also called HVAC (for Heating, Ventilation and Air-Conditioning), can be supplied with either air outside the vehicle (also called fresh air) or with recirculation air. that is to say from the passenger compartment of the vehicle.
L'air extérieur est généralement peu chargé en humidité, lorsqu'il est froid, par comparaison avec l'air de recyclage, mais peut être relativement froid, en particulier en conditions hivernales. L'air de recyclage a généralement un taux d'humidité supérieur à l'air extérieur, et est à une température proche de la température à atteindre, c'est-à-dire proche de la température de consigne définie par exemple par le conducteur ou le passager.  Outside air is generally low in moisture when it is cold compared to recirculating air, but can be relatively cold, especially in winter conditions. The recirculation air generally has a humidity level higher than the outside air, and is at a temperature close to the temperature to be reached, that is to say close to the set temperature defined for example by the driver. or the passenger.
Suivant les conditions de fonctionnement, il peut donc être particulièrement intéressant d'utiliser de l'air extérieur pour l'introduire dans l'habitacle au niveau des buses de dégivrage situées à proximité du pare- brise, après chauffage au travers du dispositif précité par exemple. Le taux d'humidité de l'air frais étant relativement faible, le risque de générer de la buée sur le pare-brise est donc également faible. A l'inverse, il peut être avantageux d'utiliser de l'air de recyclage pour le rejeter dans l'habitacle au niveau des buses de pieds. De cette manière, même en conditions hivernales et lorsqu'un débit d'air important est demandé par le conducteur ou le passager, il est possible de réchauffer plus rapidement cet air de recyclage à la température de consigne avant qu'il ne soit rejeté dans l'habitacle. Le confort pour les utilisateurs est grandement amélioré et le risque de générer de la buée sur le pare-brise est faible, cet air de recyclage étant rejeté à distance du pare-brise. Depending on the operating conditions, it may therefore be particularly advantageous to use outside air to introduce it into the cabin at the defrosting nozzles located near the windshield, after heating through the aforementioned device by example. As the humidity level of the fresh air is relatively low, the risk of generating fogging on the windshield is therefore also low. Conversely, it may be advantageous to use recirculation air to reject it in the passenger compartment at the foot nozzles. In this way, even in winter conditions and when a large air flow is requested by the driver or the passenger, it is possible to heat up this recirculation air more quickly to the set temperature before it is rejected in the winter. the cockpit. The comfort for the users is greatly improved and the risk of generating fog on the windshield is low, this recycling air being rejected away from the windshield.
Afin de profiter de tels avantages, il est important de pouvoir dissocier les flux d'air (air extérieur - air de recyclage), en particulier lors du passage desdits flux d'air au travers du dispositif de chauffage, ventilation et/ou climatisation.  In order to take advantage of such advantages, it is important to be able to dissociate the air flows (outside air - recirculation air), in particular during the passage of said air flows through the heating, ventilation and / or air conditioning device.
Un dispositif de chauffage, ventilation et/ou climatisation, également appelé HVAC (pour Heating, Ventilation and Air-Conditioning, en anglais) comporte classiquement un unique canal de circulation d'air équipé d'une roue à ailettes entraînée en rotation par un moteur électrique afin de puiser l'air dans le canal de circulation d'air.  A heating, ventilation and / or air conditioning device, also called HVAC (heating, ventilation and air-conditioning, in English) conventionally comprises a single air circulation channel equipped with a finned wheel rotated by an engine to draw air into the airflow channel.
Afin de garantir la séparation entre les deux flux d'air tout en pouvant sélectionner ou ajuster au mieux le type d'air à délivrer, l'invention propose un dispositif de génération d'un flux d'air comportant au moins un premier canal de circulation d'air et au moins un second canal de circulation d'air, des moyens de génération d'un premier flux d'air situés dans le premier canal et des moyens de génération d'un second flux d'air situés dans le second canal. Selon l'invention, le dispositif comprend un organe mobile situé en aval des moyens de génération du premier flux d'air et des moyens de génération du second flux d'air, ledit organe étant mobile entre une position d'ouverture des premier et second canaux et une position d'obturation dans laquelle il obture, au moins partiellement, le premier canal ou le second canal, et/ou dans toute position intermédiaire située entre ladite position d'ouverture et ladite position d'obturation. Les termes amont et aval sont définis par référence au sens de circulation des flux d'air. In order to guarantee the separation between the two air streams while being able to select or adjust the type of air to be delivered, the invention proposes a device for generating an air flow comprising at least a first air channel. air circulation and at least a second air circulation channel, means for generating a first air flow located in the first channel and means for generating a second air flow located in the second channel; channel. According to the invention, the device comprises a movable member located downstream of the means for generating the first air flow and means for generating the second air flow, said member being movable between an open position of the first and second channels and a closed position in which it closes, at least partially, the first channel or the second channel, and / or in any intermediate position between said open position and said closed position. The terms upstream and downstream are defined by reference to the flow direction of the air flows.
Le premier canal de circulation d'air du corps principal peut alors alimenter par exemple les buses de dégivrage situées à proximité du pare- brise et le second canal de circulation d'air peut alors alimenter les buses de pieds. De l'air extérieur ou de l'air de recyclage peut circuler dans le premier canal ou dans le second canal. En fonction de la position de l'organe mobile, il est par exemple possible de sélectionner ou d'ajuster le type d'air à délivrer.  The first air flow channel of the main body can then feed for example the defrosting nozzles located near the windshield and the second air circulation channel can then feed the foot nozzles. Outside air or recirculating air can flow in the first channel or in the second channel. Depending on the position of the movable member, it is for example possible to select or adjust the type of air to be delivered.
L'invention peut s'appliquer à tout type de dispositif répondant au problème technique précité et n'est pas limitée aux dispositifs de type HVAC.  The invention can be applied to any type of device responding to the aforementioned technical problem and is not limited to HVAC type devices.
De préférence, dans sa position d'obturation, l'organe mobile permet le passage d'air depuis le canal qui n'est pas obturé vers la partie du canal obturé qui est située en aval de l'organe mobile.  Preferably, in its closed position, the movable member allows the passage of air from the channel which is not closed to the portion of the closed channel which is located downstream of the movable member.
Dans ce cas, le premier canal et le second canal peuvent être séparés par une cloison, au moins dans leurs parties situées en aval de l'organe mobile, ladite cloison comportant une ouverture permettant le passage d'air entre les deux canaux, ladite ouverture étant fermée par l'organe mobile en position d'ouverture de celui-ci, ladite ouverture étant ouverte par l'organe mobile en position d'obturation de celui-ci.  In this case, the first channel and the second channel may be separated by a partition, at least in their parts located downstream of the movable member, said partition having an opening for the passage of air between the two channels, said opening being closed by the movable member in the open position thereof, said opening being open by the movable member in the closed position thereof.
Les moyens de génération du premier flux d'air et/ou les moyens de génération du second flux d'air peuvent comporter au moins une roue à ailettes.  The means for generating the first air flow and / or the means for generating the second air flow may comprise at least one impeller.
L'organe mobile peut comporter au moins un volet sensiblement plan.  The movable member may comprise at least one substantially plane flap.
De plus, l'organe mobile peut comporter au moins un volet tambour.  In addition, the movable member may comprise at least one drum flap.
En outre, l'organe mobile peut comporter un volet unique.  In addition, the movable member may comprise a single flap.
Par ailleurs, l'organe mobile peut être situé entre les moyens de génération des flux d'air et un échangeur de chaleur, par exemple un évaporateur. Le fait d'agencer l'organe mobile entre les moyens de génération des flux d'air et l'évaporateur permet de simplifier l'entrée d'air pour chaque canal . En effet, l'organe mobile permettant l'ouverture et/ou la fermeture d'un canal, il permet de réguler les débits d'air circulant dans chaque canal. Il est alors possible de supprimer les volets normalement situés en amont des moyens de générations des flux d'air, en ayant qu'un seul et unique organe mobile régulant le débit dans chaque canal. Le fait d'avoir un seul et unique organe mobile régulant le débit d'air dans chacun des canaux est plus simple que d'avoir deux canaux séparés par une cloison avec deux volets, chacun étant situé à l'entrée de chaque canal . Furthermore, the movable member may be located between the means for generating the air flows and a heat exchanger, for example a evaporator. Arranging the movable member between the means for generating the air flows and the evaporator makes it possible to simplify the entry of air for each channel. Indeed, the movable member for opening and / or closing a channel, it allows to regulate the flow rates of air flowing in each channel. It is then possible to remove the flaps normally located upstream of the generation means air flows, having a single mobile member regulating the flow rate in each channel. Having a single movable member regulating the flow of air in each of the channels is simpler than having two channels separated by a partition with two flaps, each located at the entrance of each channel.
L'invention concerne également une installation de chauffage, ventilation et/ou climatisation, comprenant un dispositif de génération d'un flux d'air du type précité.  The invention also relates to a heating, ventilation and / or air conditioning system, comprising a device for generating an air flow of the aforementioned type.
L'invention concerne en outre un véhicule automobile comportant une installation de chauffage, ventilation et/ou climatisation du type précité.  The invention further relates to a motor vehicle having a heating, ventilation and / or air conditioning system of the aforementioned type.
L'invention sera mieux comprise et d'autres détails, caractéristiques et avantages de l'invention apparaîtront à la lecture de la description suivante faite à titre d'exemple non limitatif en référence aux dessins annexés dans lesquels :  The invention will be better understood and other details, characteristics and advantages of the invention will appear on reading the following description given by way of non-limiting example with reference to the accompanying drawings in which:
la figure 1 est une vue schématique de face d'un dispositif de chauffage, ventilation et/ou climatisation selon l'invention, en position d'ouverture de l'organe mobile,  FIG. 1 is a diagrammatic front view of a heating, ventilation and / or air conditioning device according to the invention, in the open position of the movable member,
la figure 2 est une vue schématique de côté du dispositif de la figure 1 ,  FIG. 2 is a schematic side view of the device of FIG. 1,
la figure 3 est une vue correspondant à la figure 1 , illustrant une position d'obturation de l'organe mobile.  Figure 3 is a view corresponding to Figure 1, illustrating a closed position of the movable member.
Les figures 1 à 3 représentent un dispositif de chauffage, ventilation et/ou climatisation 1 selon une forme de réalisation de l'invention. Celui-ci est destiné à équiper un véhicule automobile et comporte un corps 2 délimitant un premier canal de circulation de fluide 3 et un second canal de circulation de fluide 4. Le corps comprend des moyens aptes à puiser l'air. Ces moyens comprennent une première roue à ailettes 5 montée dans le premier canal de circulation de fluide 3 et apte à générer un premier flux d'air F1 , et une seconde roue à ailettes 6 montée dans le second canal de circulation de fluide 4 et apte à générer un second flux d'air F2, ces deux roues 5, 6 étant entraînées par un même moteur électrique, non représenté. Figures 1 to 3 show a heating device, ventilation and / or air conditioning 1 according to one embodiment of the invention. It is intended to equip a motor vehicle and comprises a body 2 defining a first fluid circulation channel 3 and a second channel of circulation of fluid 4. The body comprises means capable of drawing air. These means comprise a first impeller 5 mounted in the first fluid circulation channel 3 and capable of generating a first air flow F1, and a second impeller 6 mounted in the second fluid circulation channel 4 and adapted to to generate a second air flow F2, these two wheels 5, 6 being driven by the same electric motor, not shown.
Les premier et second canaux de circulation d'air 3, 4 sont séparés par une cloison ou paroi de séparation 7, en aval des roues à ailettes 5, 6 dans le sens de circulation de l'air.  The first and second air circulation channels 3, 4 are separated by a partition or partition wall 7, downstream of the finned wheels 5, 6 in the direction of air flow.
Ladite paroi de séparation 7 comporte une ouverture 8 permettant le passage d'air entre les deux canaux 3, 4, un organe mobile 9, tel par exemple qu'un volet, étant monté pivotant sur la cloison 7 au niveau de ladite ouverture 8.  Said partition wall 7 has an opening 8 allowing the passage of air between the two channels 3, 4, a movable member 9, such as for example a flap, being pivotally mounted on the partition 7 at said opening 8.
L'organe mobile 9 est apte à pivoter entre une position d'ouverture des premier et second canaux 3, 4 (figure 1 ), dans laquelle il s'étend dans le plan de la cloison 7 en fermant l'ouverture 8, et une position d'obturation (figure 3). Dans sa position d'ouverture, l'organe mobile 9 ne s'oppose pas au passage de l'air dans les canaux 3, 4. A l'inverse, dans sa position de fermeture, l'organe mobile 9 obture en tout ou partie l'un des deux canaux 3,4 (en particulier le canal 4 sur la figure 3), en libérant ou ouvrant l'ouverture 8. Dans cette position, le flux d'air F1 issu de la roue à ailettes 5 peut circuler dans le canal 3 et dans le canal 4, en traversant l'ouverture 8. Dans cette position également, le second flux d'air F2 issu de la roue à ailettes 6 est bloqué par l'organe mobile 9 et ne débouche pas ou peu dans la zone du canal 4 située en aval du volet mobile 9.  The movable member 9 is pivotable between an open position of the first and second channels 3, 4 (Figure 1), in which it extends in the plane of the partition 7 by closing the opening 8, and a shutter position (Figure 3). In its open position, the movable member 9 does not oppose the passage of air in the channels 3, 4. Conversely, in its closed position, the movable member 9 closes in all or part one of the two channels 3,4 (in particular the channel 4 in Figure 3), by releasing or opening the opening 8. In this position, the air flow F1 from the impeller 5 can flow in the channel 3 and in the channel 4, passing through the opening 8. In this position also, the second air flow F2 coming from the impeller 6 is blocked by the movable member 9 and does not open or close in the zone of the channel 4 situated downstream of the mobile shutter 9.
L'air circulant dans les canaux peut être de l'air de recyclage, c'est- à-dire issu de l'habitacle du véhicule et/ou de l'air extérieur au véhicule. Il est donc possible de réguler les débits d'air extérieur et d'air de recyclage circulant dans chaque canal avec un seul et unique organe mobile.  The air circulating in the channels may be recirculating air, that is to say coming from the passenger compartment of the vehicle and / or air outside the vehicle. It is therefore possible to regulate the flow rates of outside air and recirculating air circulating in each channel with a single mobile member.
