Description

L'invention a trait à un bac à condensats destiné à être installé sous un échangeur air-liquide dans un appareil de traitement d'air.The invention relates to a condensate tray for installation under an air-liquid exchanger in an air treatment unit.

Dans le domaine du traitement de l'air il est connu qu'un appareil comporte un filtre, un groupe moto ventilateur et un échangeur thermique. Un tel appareil, qui est généralement monté en tout ou partie dans un faux plafond, aspire l'air, le filtre et fait varier sa température avant de le refouler dans la pièce. Sa fonction est de garantir la qualité de l'air par la filtration et de tempérer la pièce en proposant un échange thermique entre l'air aspiré et un fluide chaud, pour réchauffer la pièce, ou froid, pour la refroidir. A ce titre, l'air admis possède une certaine humidité qui, s'il est destiné à être refroidi par l'appareil, peut provoquer de la condensation sur l'échangeur. Cette condensation s'écoule par gravité le long de l'échangeur. Si elle n'est pas évacuée par un dispositif approprié, elle peut dégrader l'appareil et nuire à la structure du bâtiment. Les vannes et raccords servant à connecter l'appareil au réseau d'eau sont en général à l'extérieur de l'appareil. Ces équipements eux-mêmes peuvent également générer de la condensation. La condensation doit donc être récupérée à l'intérieur et à l'extérieur de l'appareil et canalisée pour son évacuation. C'est pourquoi il est connu de disposer un bac à condensats sous l'échangeur air-eau d'un appareil de traitement de l'air utilisé pour le refroidissement d'une pièce.In the field of air treatment it is known that an apparatus comprises a filter, a motorcycle fan unit and a heat exchanger. Such an apparatus, which is generally mounted wholly or partly in a false ceiling, sucks the air, the filter and varies its temperature before pushing it back into the room. Its function is to guarantee the quality of the air by filtration and to temper the room by proposing a heat exchange between the sucked air and a hot fluid, to warm the room, or cold, to cool it. As such, the intake air has a certain humidity which, if it is intended to be cooled by the apparatus, may cause condensation on the exchanger. This condensation flows by gravity along the heat exchanger. If it is not evacuated by an appropriate device, it can degrade the device and adversely affect the structure of the building. The valves and connections used to connect the unit to the water supply are usually outside the unit. This equipment itself can also generate condensation. Condensation must be collected inside and outside the unit and channeled for evacuation. This is why it is known to have a condensate tray under the air-water heat exchanger of an air handling unit used for cooling a room.

Les bacs à condensats sont en général métalliques. Il s'agit de pièces formées par pliage, soudage ou emboutissage de tôle. Ces pièces doivent être peintes pour résister à la corrosion. Afin de limiter la formation de condensats en partie externe de tels bacs, ceux-ci sont généralement isolés par l'adjonction d'un isolant collé sur leurs surfaces se trouvant à l'extérieur de l'appareil.The condensate trays are usually metallic. These are parts formed by bending, welding or sheet metal stamping. These parts must be painted to resist corrosion. In order to limit the formation of condensates in the external part of such tanks, they are generally isolated by the addition of insulating glued on their surfaces located outside the apparatus.

Il est également connu de concevoir un bac à condensats en matériau synthétique. Pour permettre l'évacuation des condensats, un tel bac est le plus souvent monté de manière inclinée dans l'appareil de traitement de l'air. Il en résulte la création d'un espace entre le bac à condensats et l'échangeur, qui est généralement monté à l'horizontal. Ainsi, il devient possible pour une partie de l'air qui traverse l'appareil de passer entre l'échangeur et le bac à condensats, sans passer à travers l'échangeur. Ceci diminue le rendement énergétique de l'appareil de traitement de l'air.It is also known to design a condensate tray made of synthetic material. To permit the evacuation of the condensates, such a tank is most often mounted in an inclined manner in the air treatment apparatus. This results in the creation of a space between the condensate pan and the exchanger, which is generally mounted horizontally. Thus, it becomes possible for some of the air passing through the apparatus to pass between the exchanger and the condensate tray, without passing through the exchanger. This decreases the energy efficiency of the air handler.

Par exemple, EP-A-2 159 497 divulgue un bac à condensats destiné à être installé sous un échangeur air-liquide appartenant à un climatiseur. Dans ce document, l'échangeur air-liquide est cintré en forme de L et repose sur plusieurs plateformes réception prévues dans le bac à condensats. Le bac à condensats comprend des rigoles ayant une surface inclinée et qui convergent vers un piquage d'évacuation. Le fait que l'échangeur repose sur les plateformes de réception disjointes engendre la création d'espaces entre le bac à condensats et l'échangeur. Plus précisément, ces espaces sont disposés entre les plateformes de réception de l'échangeur. Cela provoque un détournement d'une partie du flux d'air et diminue le rendement énergétique de l'appareil. Par ailleurs, lorsque le piquage d'évacuation des condensats est fermé, les condensats s'accumulent dans le bac, ce qui implique une saturation rapide du bac. Finalement, ce bac est réalisé en métal, ce qui augmente le coût final du climatiseur.For example, EP-A-2 159 497 discloses a condensate tray for installation under an air-liquid exchanger belonging to an air conditioner. In this document, the air-liquid exchanger is bent in the shape of an L and rests on several platforms reception in the condensate pan. The condensate pan has channels with an inclined surface that converge to an exhaust connection. The fact that the exchanger rests on the disjoint receiving platforms causes the creation of spaces between the condensate tray and the exchanger. More specifically, these spaces are arranged between the receiving platforms of the exchanger. This causes a diversion of part of the airflow and decreases the energy efficiency of the device. In addition, when the condensate drain connection is closed, the condensates accumulate in the tank, which implies a rapid saturation of the tank. Finally, this tray is made of metal, which increases the final cost of the air conditioner.

C'est à ces inconvénients qu'entend plus particulièrement remédier l'invention en proposant un nouveau bac à condensats de fabrication aisée et économique et qui permet de limiter les pertes thermiques dans un appareil de traitement de l'air.It is these drawbacks that the invention intends to remedy more particularly by proposing a new condensate tray that is easy and economical to manufacture and that makes it possible to limit heat losses in an air-handling unit.

A cet effet, l'invention concerne un bac à condensats destiné à être installé sous un échangeur air-liquide dans un appareil de traitement de l'air, ce bac étant monobloc et pourvu d'au moins un piquage d'évacuation des condensats. Conformément à l'invention, le bac est réalisé en matériau synthétique moulé et comprend une unique surface plane d'appui d'une partie de l'échangeur et au moins une rigole à fond incliné, par rapport à cette surface plane, en direction d'un premier volume de stockage temporaire des condensats raccordé au piquage d'évacuation. Il comprend également un deuxième volume de stockage temporaire des condensats en communication avec le premier volume de stockage, ce deuxième volume de stockage étant ménagé, le long d'un axe longitudinal du bac, au niveau de la rigole.To this end, the invention relates to a condensate tray intended to be installed under an air-liquid exchanger in an air handling unit, this tank being integral and provided with at least one condensate discharge tapping. According to the invention, the tank is made of molded synthetic material and comprises a single flat bearing surface of a portion of the heat exchanger and at least one inclined bottom channel, with respect to this flat surface, in the direction of a first temporary condensate storage volume connected to the exhaust connection. It also comprises a second temporary condensate storage volume in communication with the first storage volume, this second storage volume being provided along the longitudinal axis of the tank, at the level of the channel.

Grâce à l'invention, la surface plane peut servir de support à l'échangeur sans que soit créé, entre l'échangeur et le bac, un espace d'infiltration d'air parasite. Le rendement thermique d'un appareil de traitement d'air incorporant un tel bac est donc amélioré. Le fond incliné de la ou des rigole(s) permet l'écoulement des condensats par gravité vers le volume de stockage temporaire et le piquage d'évacuation, tout en conservant horizontale la surface plane d'appui. De plus, le deuxième volume de stockage temporaire des condensats empêche une saturation rapide du bac, lorsque le piquage d'évacuation est fermé.Thanks to the invention, the flat surface can serve as a support for the exchanger without being created, between the exchanger and the tray, a parasitic air infiltration space. The thermal efficiency of an air handling unit incorporating such a tray is therefore improved. The inclined bottom of the channel (s) allows the flow of condensate by gravity to the temporary storage volume and the discharge stitching, while maintaining horizontal flat bearing surface. In addition, the second volume of temporary storage condensates prevents rapid saturation of the tray, when the exhaust connection is closed.

Selon des aspects avantageux mais non obligatoires de l'invention, un tel bac à condensats peut inclure une ou plusieurs des caractéristiques suivantes, prises dans toute combinaison techniquement admissible :

  • Le bac comprend deux rigoles à fond incliné disposées de part et d'autre de la surface plane d'appui.

  • Le bac comprend au moins une nervure d'isolement d'une partie du premier volume de stockage temporaire des condensats par rapport à l'extérieur de l'échangeur.

La figure 1 est une vue en perspective d'un appareil 2 de traitement de l'air destiné au refroidissement de l'air dans une pièce. L'appareil 2 est un ventilo-convecteur qui est prévu pour être disposé à l'intérieur d'une pièce. L'appareil 2 comprend une carcasse 4 qui définit un canal de circulation de l'air entrant par un orifice O1 et sortant par un orifice O2 l'orifice O1 étant non visible sur la figure 1 mais visible sur la figure 7. Sur la figure 1, les flèches A représentent l'écoulement de l'air entrant et sortant de l'appareil 2.The figure 1 is a perspective view of an air handling apparatus 2 for cooling air in a room. The apparatus 2 is a fan coil which is intended to be disposed within a room. The apparatus 2 comprises a carcass 4 which defines a channel for the flow of air entering through an orifice O 1 and exiting through an orifice O 2, the orifice O 1 being non-visible on the figure 1 but visible on the figure 7 . On the figure 1 , the arrows A represent the flow of air entering and leaving the apparatus 2.

L'appareil 2 comprend un groupe moto ventilateur 6 et une unité 8 d'alimentation et de commande du groupe 6. L'appareil 2 comprend également un filtre non représenté et qui peut, par exemple, être disposé au niveau de l'orifice d'entrée O1.The apparatus 2 comprises a motorcycle fan unit 6 and a unit 8 for supplying and controlling the group 6. The apparatus 2 also comprises a filter, not shown, and which can, for example, be arranged at the level of the orifice d input O 1 .

L'appareil 2 comprend également un échangeur air-eau 10 qui comprend plusieurs tubes 102 dont un seul est visible sur la figure 4 par arrachement, ces tubes étant raccordés entre eux par des coudes 103 et parallèles chacun à un axe longitudinal X10 de l'échangeur 10.The apparatus 2 also comprises an air-water exchanger 10 which comprises several tubes 102 of which only one is visible on the figure 4 by tearing off, these tubes being interconnected by bends 103 and each parallel to a longitudinal axis X10 of the exchanger 10.

L'eau circulant dans l'échangeur 10 peut être additivée ou non, par exemple avec du glycol. En variante, à la place d'eau, on utilise un autre liquide caloporteur, par exemple de type R134A (fréon).The water flowing in the exchanger 10 can be additive or not, for example with glycol. Alternatively, instead of water, another heat transfer liquid, for example R134A (Freon).

Les tubes 102 traversent des ailettes 104 qui sont planes et orthogonales à l'axe X10. En variante, les ailettes 104 peuvent être gaufrées. Pour la clarté du dessin, seules certaines ailettes 104 sont représentées aux figures 4 et 6. Les ailettes 104 sont disposées entre deux platines d'extrémité 106 et 108. Les coudes 103 sont à 180° et relient deux tubes 102 à l'extérieur du volume défini entre les platines d'extrémité 106 et 108. Des raccords 110 sont disposés à l'extrémité de certains des tubes 102. Ils sont supportés par des équerres 112 en tôle pliée et permettent d'alimenter les tubes 102 en eau de refroidissement en montant des vannes directement sur l'échangeur 10.The tubes 102 pass through fins 104 which are flat and orthogonal to the axis X10. Alternatively, the fins 104 may be embossed. For the sake of clarity, only certain fins 104 are shown in FIGS. figures 4 and 6 . The fins 104 are disposed between two end plates 106 and 108. The bends 103 are at 180 ° and connect two tubes 102 outside the volume defined between the end plates 106 and 108. Fittings 110 are arranged to the end of some of the tubes 102. They are supported by brackets 112 bent sheet and allow to supply the tubes 102 cooling water by mounting valves directly on the exchanger 10.

On note S10 la surface inférieure de l'échangeur 10 formée par les tranches inférieures de chacune des ailettes 104 et par les deux bords inférieurs 1062 et 1082 des platines 106 et 108. La surface S10 est la surface par laquelle repose l'échangeur 10 lorsqu'il est placé sur une surface plane et horizontale.S10 denotes the lower surface of the exchanger 10 formed by the lower slices of each of the fins 104 and the two lower edges 1062 and 1082 of the plates 106 and 108. The surface S10 is the surface on which the heat exchanger 10 rests when it is placed on a flat and horizontal surface.

L'appareil 2 comprend également un bac à condensats 20 monobloc et réalisé par moulage d'un matériau synthétique tel qu'un matériau thermoplastique. A titre d'exemple le bac 20 peut être moulé en ABS, polypropylène, polyéthylène ou polyamide naturels. Le matériau choisi pour le moulage peut être additivé de matières minérales ou organiques telles que du talc, des fibres de verre ou des fibres de bambou.The apparatus 2 also comprises a monobloc condensate tray 20 made by molding a synthetic material such as a thermoplastic material. By way of example, the tray 20 can be molded of natural ABS, polypropylene, polyethylene or polyamide. The material chosen for molding may be additive of mineral or organic materials such as talc, glass fibers or bamboo fibers.

Le bac à condensats 20 est composé d'une partie 202 interne à l'appareil et d'une partie 204 externe à l'appareil. En configuration montée de l'appareil, la partie 202 est disposée dans le volume intérieur de la carcasse 4 et en dessous des ailettes 104 de l'échangeur air-eau 10. La partie 204 est, en configuration montée, placée sous les parties 103, 110 et 112 de l'échangeur 10, du côté de la platine d'extrémité 106. On note X20 un axe longitudinal du bac 20 le long duquel se succèdent les parties 204 et 202.The condensate tray 20 is composed of a portion 202 internal to the device and a portion 204 external to the device. In the mounted configuration of the apparatus, the portion 202 is disposed in the interior volume of the carcass 4 and below the fins 104 of the air-water heat exchanger 10. The portion 204 is, in mounted configuration, placed under the parts 103 , 110 and 112 of the exchanger 10, the side of the end plate 106. Note X20 a longitudinal axis of the tray 20 along which follow the parts 204 and 202.

La partie 202 a, vue de dessus, une forme globalement rectangulaire allongée selon l'axe X20. Une portion centrale 206 de la partie 202 s'étend de part et d'autre de l'axe X20 sur l'essentiel de la longueur de la partie 202. On note S206 la surface supérieure de la portion centrale 206, cette surface étant orientée vers le haut en configuration d'utilisation du bac 20. Cette surface 206 est plane, parallèle à l'axe X20 et horizontale en configuration d'utilisation du bac 20. La surface S206 a une forme de T avec un pied très allongé S206A et deux branches relativement courtes S206B et S206C. La surface S206 est donc d'un seul tenant.Part 202 has, seen from above, a generally rectangular shape elongated along the axis X20. A central portion 206 of the portion 202 extends on either side of the axis X20 over most of the length of the portion 202. S206 denotes the upper surface of the central portion 206, this surface being oriented upwards in the configuration of use of the tray 20. This surface 206 is flat, parallel to the axis X20 and horizontal in the configuration of use of the tray 20. The surface S206 has a shape of T with a very elongated foot S206A and two relatively short branches S206B and S206C. The surface S206 is therefore in one piece.

De part et d'autre de la portion centrale 206, la partie interne 202 comprend deux rigoles 208 et 210 qui s'étendent parallèlement à l'axe X20. On note respectivement 212 et 214 les fonds des rigoles 208 et 210. La profondeur des rigoles 208 et 210 augmente en se rapprochant de la partie 204. En d'autres termes les fonds 212 et 214 sont inclinés vers le bas en direction de la partie 204. Ces fonds 212 et 214 sont donc inclinés par rapport à la surface S206 qui est horizontale en configuration d'utilisation, comme mentionnée ci-dessus. On note α1 l'angle d'inclinaison des fonds 212 et 214 par rapport à la surface S206.On either side of the central portion 206, the inner portion 202 comprises two channels 208 and 210 which extend parallel to the axis X20. 212 and 214 are the bottoms of channels 208 and 210 respectively. The depth of channels 208 and 210 increases as it gets closer to part 204. In other words, the bottoms 212 and 214 are inclined downwards in the direction of the part 204. These funds 212 and 214 are therefore inclined relative to the surface S206 which is horizontal in the configuration of use, as mentioned above. Α 1 is the tilt angle of the funds 212 and 214 relative to the surface S206.

A son extrémité opposée à la partie 204 chaque rigole 208 et 210 se termine par un épaulement 216 perpendiculaire à l'axe X20. Du côté de la partie 204 la rigole 208 débouche sur une gouttière 218. Vue de dessus la gouttière a une forme de U à fond plat dont les deux branches 220 et 222 communiquent avec deux piquages 224 et 226 alignés sur un axe Y20 orthogonal à l'axe X20. De même la rigole 210 débouche sur la gouttière 218 du côté de la partie 204. Le fond 219 de la gouttière 218 est dans le prolongement des fonds 212 et 214 dans les zones de jonction des rigoles 208 et 210 avec la gouttière 218. Lorsque les piquages 224 et 226 sont obturés, la gouttière 218 constitue un volume de stockage temporaire des condensats.At its end opposite the portion 204 each channel 208 and 210 ends with a shoulder 216 perpendicular to the axis X20. On the side of the portion 204 the channel 208 opens on a gutter 218. View from above the gutter has a flat-bottomed U-shape whose two branches 220 and 222 communicate with two branches 224 and 226 aligned on an axis Y20 orthogonal to the X20 axis. Similarly, the trough 210 opens onto the trough 218 on the side of the part 204. The bottom 219 of the trough 218 is in the extension of the bottoms 212 and 214 in the junction areas of the channels 208 and 210 with the trough 218. When the connections 224 and 226 are closed, the gutter 218 constitutes a temporary storage volume condensates.

Une languette 228 obture partiellement chacune des rigoles 208 et 210 au niveau de leur jonction avec la gouttière 218. Ainsi la section de passage des condensats est réduite au niveau des languettes 228.A tab 228 partially closes each of the channels 208 and 210 at their junction with the channel 218. Thus the condensates passage section is reduced at the tabs 228.

Une cavité 230 est aménagée dans la portion centrale 206. Cette cavité est située, le long de l'axe X20, au niveau des parties les plus profondes des rigoles 208 et 210 à proximité de leurs extrémités aval par lesquelles elles débouchent dans la gouttière 218. La cavité 230 est en communication fluidique avec la gouttière 218 à travers une ouverture obturée partiellement par des languettes 232.A cavity 230 is formed in the central portion 206. This cavity is located, along the axis X20, at the deepest portions of the channels 208 and 210 near their downstream ends through which they open into the gutter 218 The cavity 230 is in fluid communication with the trough 218 through an opening partially closed by tabs 232.

La partie interne 202 comporte sur chacun de ses bords longitudinaux un crochet 234 ou 236.The inner portion 202 has on each of its longitudinal edges a hook 234 or 236.

On note 237 le bord transversal de la partie 202 opposée à la partie 204. Les bords longitudinaux de la partie 202 dépassent au-delà du bord 237 sous la forme de bandes en saillie 238 et 240.237 is the transverse edge of the portion 202 opposite the portion 204. The longitudinal edges of the portion 202 protrude beyond the edge 237 in the form of protruding strips 238 and 240.

Deux pions 242 et 244 dépassent de la surface S206 au voisinage du bord transversal 237.Two pins 242 and 244 protrude from the surface S206 in the vicinity of the transverse edge 237.

La partie 204 comprend un voile plan 246 et un bord périphérique 248 perpendiculaire à la surface S206. Le voile 246 est incliné vers le bas en direction de la gouttière 218. Comme le voile 246 est incliné, on note α2 l'angle entre la surface supérieure S246 du voile 246 et l'axe X20, c'est-à-dire entre le voile 246 et la surface 206.Part 204 comprises a planar web 246 and a peripheral edge 248 perpendicular to the surface S206. The web 246 is inclined downwards towards the channel 218. As the web 246 is inclined, α2 is the angle between the upper surface S246 of the web 246 and the axis X20, that is to say between the web 246 and the surface 206.

La valeur de l'angle α1 est comprise entre 0,5° et 5°, une valeur de l'angle α1 supérieure à 5° imposant une épaisseur trop importante au bac. La valeur de l'angle α2 est comprise entre 0,5 et 15°. Dans le mode de réalsation décrit dans les figures 1 à 11, les valeurs α1 et α2 valent respectivement 0,9° et 3,5°. En pratique l'angle α2 est supérieur à l'angle α1. Le voile 246 est donc plus incliné par rapport à la surface S206 que les fonds 212 et 214 des rigoles 208 et 210, ce qui implique un renvoi plus franc des condensats s'écoulant sur le voile 246 en direction de la gouttière 218. Comme il ressort de la figure 6 il existe un décalage vertical Δ entre le bord inférieur 250 du voile 246 et le fond 219 de la gouttière 218. Ainsi les condensats présents dans la gouttière 218 n'ont pas tendance à remonter sur le voile 246.The value of the angle α1 is between 0.5 ° and 5 °, a value of the angle α1 greater than 5 ° imposing too much thickness to the tray. The value of the angle α2 is between 0.5 and 15 °. In the rehearsal mode described in Figures 1 to 11 , the values α1 and α2 are respectively 0.9 ° and 3.5 °. In practice, the angle α2 is greater than the angle α1. The sail 246 is therefore more inclined with respect to the surface S206 than the bottoms 212 and 214 of the channels 208 and 210, which implies a more direct return of the condensates flowing on the web 246 in the direction of the gutter 218. spring of the figure 6 there is a vertical offset Δ between the lower edge 250 of the web 246 and the bottom 219 of the gutter 218. Thus the condensates present in the gutter 218 do not tend to rise on the web 246.

Un déflecteur 12 est monté à l'intérieur de la carcasse 4 et s'étend entre ses parois latérales 46 et 48. Ce déflecteur comprend un bord rabattu 122 destiné à interagir avec le crochet 234 pour guider le bac 20 en translation selon une direction D20 parallèle à l'axe X20 et perpendiculaire aux flèches A entre la position représentée à la figure 7, avec omission de l'échangeur 10, et la position représentée à la figure 1 où le bac 20 est disposé sous l'échangeur 10 avec la partie 202 reçue à l'intérieur de la carcasse 4. Comme visible à la figure 9 où le plafond 41 de la carcasse est omis pour la clarté du dessin, le bord rabattu 122 constitue un moyen de guidage du bac 20 dans son mouvement de translation selon la direction D20, entre une ouverture 03 ménagée dans une paroi latérale 46 de la carcasse 4 et la paroi latérale opposée 48.A deflector 12 is mounted inside the carcass 4 and extends between its side walls 46 and 48. This deflector comprises a folded edge 122 intended to interact with the hook 234 to guide the tray 20 in translation in a direction D20 parallel to the axis X20 and perpendicular to the arrows A between the position shown in FIG. figure 7 , with omission of the exchanger 10, and the position represented at figure 1 where the tray 20 is disposed under the exchanger 10 with the part 202 received inside the carcass 4. As visible at figure 9 where the ceiling 41 of the carcass is omitted for the sake of clarity of the drawing, the folded edge 122 constitutes a means for guiding the tray 20 in its translation movement in the direction D20, between an opening 03 formed in a side wall 46 of the carcass 4 and the opposite side wall 48.

Une pompe 14 est accrochée sur la partie 204 grâce à une platine 16 pourvue de lumières 162 de réception de deux taquets 252 ménagés sur l'extérieur du bord 248. Un conduit souple 18 relie le piquage 226 à la pompe 14, alors qu'un bouchon 19 obture le piquage 224. Lorsqu'elle n'est pas activée, la pompe 14 obture le piquage 226. On comprend que, comme deux taquets 252 sont également prévus au voisinage du piquage 224, la pompe 14 pourrait être montée au voisinage du piquage 224 et raccordée à celui-ci, alors que le piquage 226 serait obturé par le bouchon 19. Ainsi, le bac 20 permet la collecte des condensats au choix par le piquage 224 ou par le piquage 226 qui sont disposés sur deux côtés opposés du bac 20. L'implantation de la pompe 14 et le choix du piquage 224 ou 226 utilisé pour évacuer les condensats peut ainsi être effectué en tenant compte de l'environnement de l'appareil 2 et des facilités d'accès à la partie 204.A pump 14 is hooked on the part 204 thanks to a plate 16 provided with slots 162 for receiving two tabs 252 formed on the outside of the edge 248. A flexible conduit 18 connects the stitching 226 to the pump 14, while plug 19 closes the stitching 224. When it is not activated, the pump 14 closes the stitching 226. It is understood that, like two stubs 252 are also provided in the vicinity of the stitching 224, the pump 14 could be mounted in the vicinity of the stitching 224 and connected thereto, while the stitching 226 would be closed by the plug 19. Thus, the tray 20 allows the collection of condensates to choose by the stitching 224 or the stitching 226 which are arranged on two opposite sides of the tray 20. The implantation of the pump 14 and the choice of stitching 224 or 226 used to evacuate the condensates can thus be carried out taking into account the environment of the apparatus 2 and the access facilities to the part 204.

Lors du montage de l'appareil 2, l'échangeur 10 est posé sur le bac 20 en amenant les pions 242 et 244 dans deux orifices 1084 et 1086 ménagés à cet effet dans le bord 1082 de la platine 108. Les pions 242 et 244 constituent des moyens de positionnement de l'échangeur 10 sur le bac 20. Lorsque l'échangeur 10 est en position sur le bac 20 il repose par sa surface S10 sur la surface S206. Autrement dit, l'ensemble de la surface S10 de l'échangeur 10 repose sur la surface S206 si bien que l'échangeur 10 s'appuie en totalité et uniquement sur la surface S206 qui est d'un seul tenant. La platine 106 est positionnée approximativement au-dessus de la gouttière 218 et, après mise en place du bac 2 dans la carcasse 4 par translation selon la direction D20, la platine 106 obture l'ouverture O3 de la carcasse 4 visible aux figures 7 et 9 par laquelle l'échangeur 10 a préalablement été introduit dans le volume intérieur de la carcasse 4.During assembly of the apparatus 2, the exchanger 10 is placed on the tank 20 by bringing the pins 242 and 244 into two orifices 1084 and 1086 formed for this purpose in the edge 1082 of the plate 108. The pins 242 and 244 constitute means for positioning the exchanger 10 on the tank 20. When the heat exchanger 10 is in position on the tank 20 it rests by its surface S10 on the surface S206. In other words, the entire surface S10 of the exchanger 10 rests on the surface S206 so that the exchanger 10 relies entirely and solely on the surface S206 which is in one piece. The plate 106 is positioned approximately above the gutter 218 and, after placing the tray 2 in the carcass 4 by translation in the direction D20, the plate 106 closes the opening O 3 of the carcass 4 visible to the figures 7 and 9 whereby the exchanger 10 has previously been introduced into the interior volume of the carcass 4.

Dans cette configuration, et comme visible aux figures 5 et 6, le bac 20 repose sur une couche d'isolant 42 disposée sur le dessus du fond 44 de la carcasse 4, ceci au moyen de quatre nervures 254, 256, 258 et 260 qui s'étendent sur la longueur de la partie 202, parallèlement à l'axe X20 et sur le dessous du bac 20. En pratique, il suffit qu'une seule nervure du bac 20 soit en contact avec la couche 42 sur toute la longueur de la partie 202 pour créer une barrière à l'écoulement d'air de l'orifice d'entrée O1 vers le moto ventilateur 6 en dessous du bac 20.In this configuration, and as visible to figures 5 and 6 , the tray 20 rests on an insulating layer 42 disposed on the top of the bottom 44 of the carcass 4, this by means of four ribs 254, 256, 258 and 260 which extend along the length of the part 202, in parallel to the axis X20 and the underside of the tray 20. In practice, it is sufficient that a single rib of the tray 20 is in contact with the layer 42 over the entire length of the portion 202 to create a barrier to the flow of water. air from the inlet port O 1 to the motorcycle fan 6 below the tank 20.

Ainsi, lorsque le groupe moto ventilateur est actif, l'air aspiré traverse l'orifice O1 et est dirigé vers la partie de l'échangeur 10 située entre les platines 106 et 108, sans pouvoir circuler entre les ailettes 104 et le fond 44 de la carcasse 4. En effet, l'échangeur 10 repose par sa surface S10 sur la surface S206, ce qui empêche la circulation d'air entre les éléments 10 et 20. En outre, comme le bac 20 repose contre la couche d'isolant 42 par ses nervures 254 à 260, l'air ne peut pas passer sous le bac 20.Thus, when the fan motor unit is active, the air sucked passes through the orifice O 1 and is directed towards the part of the exchanger 10 located between the plates 106 and 108, without able to circulate between the fins 104 and the bottom 44 of the carcass 4. In fact, the exchanger 10 rests by its surface S10 on the surface S206, which prevents air circulation between the elements 10 and 20. In addition, as the tray 20 rests against the insulating layer 42 by its ribs 254 to 260, the air can not pass under the tray 20.

La zone de transition 262 entre la portion 206 et la rigole 208 est constituée par une bande plane et inclinée en direction de la rigole 208, c'est-à-dire avec une ligne de plus grande pente perpendiculaire à l'axe X20. De la même façon, une zone de transition 264 s'étend entre la portion 206 et la rigole 210, en étant inclinée vers la rigole 210, avec une direction de plus grande pente perpendiculaire à l'axe X20. On note α3 l'angle d'inclinaison de la surface supérieure S262 ou S264 d'une zone de transition 262 ou 264 par rapport à la surface S206. La valeur de cet angle, qui est la même pour les surfaces S262 et S264, est comprise entre 3° et 15°.The transition zone 262 between the portion 206 and the channel 208 is constituted by a flat strip inclined towards the channel 208, that is to say with a line of greater slope perpendicular to the axis X20. In the same way, a transition zone 264 extends between the portion 206 and the channel 210, being inclined towards the channel 210, with a direction of greater slope perpendicular to the axis X20. Α3 is the angle of inclination of the upper surface S262 or S264 of a transition zone 262 or 264 with respect to the surface S206. The value of this angle, which is the same for the surfaces S262 and S264, is between 3 ° and 15 °.

Comme cela ressort plus particulièrement de la figure 5, en cas de formation de gouttelettes G de condensation, celles-ci circulent le long des ailettes 104, le plus souvent à proximité de leurs bords de fuite, et tombent sur la zone 264, d'où elles s'écoulent dans la rigole 210 par gravité du fait du caractère incliné de la zone 264.As is more particularly apparent from the figure 5 , in the case of formation of condensation droplets G, these flow along the fins 104, most often close to their trailing edges, and fall on the zone 264, from where they flow into the channel 210 by gravity because of the inclined nature of the zone 264.

On remarque que l'arrête de transition entre la zone 264 et la partie 206 est située sous les bords de fuite des ailettes 104. Ainsi les condensats n'ont pas besoin d'être déplacés horizontalement par le courant d'air A avant de pouvoir s'écouler vers la rigole 210.Note that the transition edge between the zone 264 and the part 206 is located under the trailing edges of the fins 104. Thus the condensates do not need to be moved horizontally by the stream of air A before they can to flow towards the channel 210.

Dans l'exemple représenté, l'échangeur 10 comporte trois colonnes de tubes 102. En variante, cet échangeur peut comporter quatre colonnes de tels tubes. Dans ce cas, les ailettes 104 sont rallongées dans le sens du flux d'air A, au point que leurs bords de fuite se trouvent alors sensiblement au-dessus de la rigole 210, d'une façon globalement symétrique à leurs bords d'attaque qui sont sensiblement au-dessus de la rigole 208. Dans ce cas, les gouttelettes de condensats qui se forment sur les bords de fuite tombent directement par gravité dans la rigole 210, sans interférence avec la zone 264. Dans la configuration d'utilisation de l'appareil 2, les bandes en saillie 238 et 240 du bac 20 s'engagent dans des logements correspondants 492 et 494 ménagés dans une couche 49 d'isolant habillant la surface intérieure de la paroi latérale 48 de la carcasse 4 opposée à l'ouverture O3, ce qui est représenté uniquement à la figure 9. Par ailleurs, une extension 1088 d'un bord latéral 1089 de la platine 108 pénètre également dans un logement correspondant 496 ménagé dans la couche d'isolant 49. Ainsi, une circulation d'air entre la platine 108 et la paroi 48 est empêchée, ce qui garantit que l'ensemble de l'air aspiré à travers l'orifice O1 passe effectivement au niveau des ailettes 104 et des tubes 102.In the example shown, the exchanger 10 comprises three columns of tubes 102. As a variant, this exchanger may comprise four columns of such tubes. In this case, the fins 104 are lengthened in the direction of the air flow A, so that their trailing edges are then substantially above the channel 210, in a manner generally symmetrical to their leading edges. which are substantially above the channel 208. In this case, the droplets of condensates that form on the trailing edges fall directly by gravity into the channel 210, without interference with the zone 264. In the configuration of use of the apparatus 2, the protruding strips 238 and 240 of the tray 20 engage in corresponding housings 492 and 494 formed in a layer 49 of insulation covering the inner surface of the side wall 48 of the carcass 4 opposite to the opening O 3 , which is represented only at the figure 9 . Furthermore, an extension 1088 of a lateral edge 1089 of the plate 108 also penetrates into a corresponding housing 496 formed in the insulating layer 49. Thus, an air flow between the plate 108 and the wall 48 is prevented, which ensures that all of the air sucked through the orifice O 1 actually passes at the level of the fins 104 and the tubes 102.

En configuration d'utilisation, les languettes 228 limitent l'écoulement d'air vers la gouttière 218 à travers les rigoles 208 et 210. Elles évitent donc les pertes de rendement de l'appareil 2, tout en étant compatibles avec l'écoulement des condensats, avec un débit relativement faible, vers la gouttière 218.In the configuration of use, the tabs 228 limit the flow of air to the trough 218 through the channels 208 and 210. They therefore avoid losses of efficiency of the apparatus 2, while being compatible with the flow of the condensates, with a relatively low flow rate, to the gutter 218.

Si de la condensation se forme à l'extérieur de la platine 106, les condensats s'écoulent vers la partie 204 et ruissellent sur le voile 246 jusque dans la gouttière 218 et dans la cavité 230 où ils se mélangent à ceux venant des rigoles 208 et 210.If condensation forms on the outside of the plate 106, the condensates flow towards the portion 204 and flow on the web 246 into the gutter 218 and into the cavity 230 where they mix with those from the channels 208 and 210.

Tant que la pompe n'est pas activée, les condensats demeurent dans la gouttière 218 et, le cas échéant, dans la cavité 230, à l'intérieur de la carcasse 4. La cavité 230 forme donc un volume de stockage des condensats supplémentaire à la gouttière 18. Cela permet notamment d'éviter une saturation des condensats dans le bac 20 lorsque le piquage d'évacuation des condensats est fermé ou que la pompe 14 ne fonctionne pas. Quand la pompe 14 est activée, les condensats sont évacués par le piquage 226. La pompe 14 est optionnelle. En l'absence de pompe, les condensats sont évacués sous l'effet de la gravité vers les piquages de sortie 224, 226.As long as the pump is not activated, the condensates remain in the gutter 218 and, where appropriate, in the cavity 230, inside the carcass 4. The cavity 230 therefore forms a condensate storage volume which is additional to the gutter 18. This allows in particular to avoid saturation of the condensate in the tray 20 when the condensate discharge tapping is closed or the pump 14 does not work. When the pump 14 is activated, the condensates are evacuated by the tapping 226. The pump 14 is optional. In the absence of a pump, the condensates are evacuated under the effect of gravity to the outlets 224, 226.

Comme le bac 20 est pourvu de deux rigoles 208 et 210 et de deux patins 234 et 236, il peut être utilisé dans un appareil de traitement d'air avec introduction par le côté visible aux figures 7 et 9 ou par le côté opposé, au choix du concepteur de l'appareil 2.As the tray 20 is provided with two channels 208 and 210 and two pads 234 and 236, it can be used in an air treatment apparatus with introduction by the visible side to figures 7 and 9 or by the opposite side, at the choice of the designer of the apparatus 2.

Dans le deuxième mode de réalisation représenté à la figure 11, les éléments analogues à ceux du premier mode de réalisation portent les mêmes références. Dans ce qui suit, on ne décrit que ce qui distingue ce mode de réalisation du précédent.In the second embodiment shown in figure 11 elements similar to those of the first embodiment bear the same references. In what follows, only what distinguishes this embodiment from the previous one is described.

Dans ce mode de réalisation, une nervure 270 divise la gouttière 218 en une partie intérieure 218A et une partie extérieure 218B. La nervure 270 est perpendiculaire au fond 219 de la gouttière 218. Cette nervure a une hauteur lui permettant de s'étendre du fond de la gouttière jusqu'au bord inférieur 1062 d'une platine d'extrémité 106 analogue à celle du premier mode de réalisation. Les extrémités 272 et 274 de la nervure 270 se situent dans le prolongement des rigoles 208 et 210.In this embodiment, a rib 270 divides the trough 218 into an inner portion 218A and an outer portion 218B. The rib 270 is perpendicular to the bottom 219 of the channel 218. This rib has a height allowing it to extend from the bottom of the channel to the lower edge 1062 of an end plate 106 similar to that of the first mode of production. The ends 272 and 274 of the rib 270 are in the extension of the channels 208 and 210.

Du côté de la partie externe 218B de la gouttière 218, deux nervures 276, 278 prolongent le bord 248. La nervure 276 forme avec l'extrémité 272 de la nervure 270 une chicane du côté du piquage 224. De la même manière, la nervure 278 forme avec l'extrémité 274 de la nervure 270 une chicane du côté du piquage 226.On the side of the outer portion 218B of the channel 218, two ribs 276, 278 extend the edge 248. The rib 276 forms with the end 272 of the rib 270 a baffle on the side of the stitching 224. In the same way, the rib 278 forms with the end 274 of the rib 270 a baffle at the stitching side 226.

Le bac 20 est pourvu d'une cavité 230 analogue à celle du premier mode de réalisation et qui est séparée de la gouttière 218 par deux languettes 232.The tray 20 is provided with a cavity 230 similar to that of the first embodiment and which is separated from the trough 218 by two tabs 232.

On définit les languettes 228E et 228S respectivement en aval des rigoles 208 et 210. On note S228E la section de passage de l'air entre la languette 228E et la portion centrale 206. De même, on note S228S la section de passage de l'air entre la languette 228S et la portion centrale 206. La section S228E se trouvant en entrée de l'échangeur 10, côté ventilateur, ce dernier générant une pression d'air en plus d'un débit d'air, et l'échangeur générant une perte de charge d'air, la pression d'air au niveau de la section S228E est supérieure à la pression d'air au niveau de la section S228S. On utilise cette différence de pression pour canaliser les condensats vers le piquage 226.The tabs 228E and 228S are defined respectively downstream of the channels 208 and 210. The air passage section between the tongue 228E and the central portion 206. S228E is noted. Similarly, the passage section of the air between the tongue 228S and the central portion 206. The S228E section being at the inlet of the exchanger 10, fan side, the latter generating an air pressure in addition to an air flow, and the exchanger generating a loss of air pressure, the air pressure at section S228E is greater than the air pressure at section S228S. This pressure difference is used to channel the condensates to the quilting 226.

Afin de maintenir cette différence de pression en aval des sections S228E et S228S, les nervures 270, 276 et 278 isolent la partie intérieure 218A de la gouttière 218 par rapport à l'extérieur. Ainsi, la pression d'air dans la gouttière 218 au voisinage de l'extrémité 272 de la nervure 270 est supérieure à la pression d'air au voisinage de l'extrémité 274.In order to maintain this pressure difference downstream of the sections S228E and S228S, the ribs 270, 276 and 278 isolate the inner portion 218A of the trough 218 from the outside. Thus, the air pressure in the gutter 218 in the vicinity of the end 272 of the rib 270 is greater than the air pressure in the vicinity of the end 274.

L'air circulant à travers la section S228E pousse les condensats le long de la nervure 270 de part et d'autre de celle-ci, comme représenté par les flèches E à la figure 11. Il se crée deux courants de condensats, le premier du côté intérieur 218A de la gouttière 218 et le second du côté extérieur 218B de la gouttière 218. Les condensats de ce second courant contournent l'extrémité 272 de la nervure 270.The air flowing through the section S228E pushes the condensates along the rib 270 on either side of it, as represented by the arrows E at figure 11 . Two streams of condensate are created, the first of the inner side 218A of the gutter 218 and the second of the outer side 218B of the gutter 218. The condensates of this second stream bypass the end 272 of the rib 270.

Les nervures 276 et 278 constituent des déflecteurs destinés à casser le courant d'air qui contourne les extrémités 272 et 274 de la nervure 270.The ribs 276 and 278 constitute deflectors intended to break the air current which bypasses the ends 272 and 274 of the rib 270.

Les caractéristiques techniques des modes de réalisation et variantes envisagés ci-dessus peuvent être combinées entre elles.The technical characteristics of the embodiments and variants envisaged above can be combined with each other.
