Description

La présente invention est relative à un appareil de traitement de l'air et en particulier à la structure du bâti d'un tel appareil constitué par une ossature métallique rigide et une pluralité de panneaux définissant les faces de l'appareil.The present invention relates to an air treatment apparatus and in particular to the structure of the frame of such an apparatus consisting of a rigid metal frame and a plurality of panels defining the faces of the apparatus.

Dans un tel appareil, l'air peut subir toute action de refroidissement ou de réchauffement. Il peut également s'agir d'un appareil où circule de l'air aux conditions de température et d'hygrométrie différentes de l'air environnant l'appareil.In such a device, the air can undergo any cooling or heating action. It can also be a device in which air circulates at different temperature and hygrometry conditions from the air surrounding the device.

Des appareils de ce type peuvent comporter une enveloppe utilisant une ossature rigide matérialisant les arêtes du volume occupé par l'appareil et des panneaux définissant les faces dudit volume et fixés à l'ossature. Une telle ossature peut être réalisée, soit en profilés d'acier obtenus par pliage ou formage en continu, soit en profilés d'aluminium filés.Apparatuses of this type may comprise an envelope using a rigid framework materializing the edges of the volume occupied by the apparatus and panels defining the faces of said volume and fixed to the framework. Such a framework can be produced either in steel profiles obtained by bending or continuous forming, or in extruded aluminum profiles.

Lors de la réalisation d'un appareil de ce type, on rencontre un certain nombre de difficultés tenant en particulier à l'obtention d'une bonne étanchéité à l'air et à l'élimination des ponts thermiques. Il convient, de plus, de pouvoir fixer aisément les constituants internes de l'appareil et d'offrir, vis-à-vis de l'extérieur, une esthétique convenable. On notera que la présence de tels ponts thermiques se traduit généralement par des condensations de l'humidité contenue dans l'air ambiant sur les parties froides extérieures de l'appareil. Il convient donc d'éviter que les parties métalliques conductrices de la chaleur soient exposées simultanément à l'air circulant à l'intérieur de l'appareil et à l'air extérieur ou air ambiant.When making an apparatus of this type, a number of difficulties are encountered, in particular relating to obtaining good airtightness and eliminating thermal bridges. It should also be able to easily fix the internal components of the device and offer vis-à-vis the outside, a suitable aesthetic. It will be noted that the presence of such thermal bridges generally results in condensations of the humidity contained in the ambient air on the cold outside parts of the device. It is therefore advisable to avoid the metallic conductive parts of the heat being exposed simultaneously to the air circulating inside the device and to the outside air or ambient air.

La présente invention a pour objet la réalisation d'un tel appareil de traitement de l'air, dans lequel la structure du bâti permet d'obtenir une excellente étanchéité à l'air ainsi qu'une absence de continuité métallique entre le milieu intérieur et le milieu extérieur, afin de s'affranchir des fuites et ponts thermiques et des condensations à l'extérieur de l'enveloppe.The subject of the present invention is the production of such an air treatment apparatus, in which the structure of the frame makes it possible to obtain an excellent airtightness as well as a lack of metallic continuity between the interior environment and the external environment, in order to overcome thermal leaks and bridges and condensations outside the envelope.

L'invention a également pour objet un bâti pour un tel appareil qui permet un accrochage facile des composants internes, notamment sans nécessiter de perçage de l'ossature.The invention also relates to a frame for such an apparatus which allows easy hooking of the internal components, in particular without requiring drilling of the framework.

L'invention a également pour objet de permettre la fixation des panneaux latéraux par des vis extérieures accessibles à l'utilisateur sans risque de condensation externe.The invention also aims to allow the fixing of the side panels by external screws accessible to the user without risk of external condensation.

L'appareil de traitement de l'air, selon l'invention, comprend un bâti constitué par une ossature métallique rigide matérialisant en particulier les arêtes du volume occupé par l'appareil et des panneaux définissant les faces dudit volume et fixés à cette ossature. Les panneaux comprennent une paroi mince extérieure et une paroi mince intérieure enserrant une âme en matériau isolant. Un joint isolant est disposé entre l'ossature métallique rigide et au moins la paroi extérieure des panneaux. Les panneaux sont fixés sur l'ossature par des vis traversant un rebord de la paroi extérieure des panneaux ainsi que le joint isolant. De cette manière, la fixation des panneaux se fait sans entraîner la formation d'un quelconque pont thermique, le joint isolant en matière plastique étant interposé entre la paroi extérieure du panneau et l'ossature qui est soumise, quant à elle, aux conditions de température intérieures de l'appareil.The air treatment device according to the invention comprises a frame constituted by a rigid metal frame materializing in particular the edges of the volume occupied by the device and panels defining the faces of said volume and fixed to this frame. The panels include an outer thin wall and an inner thin wall enclosing a core of insulating material. An insulating joint is placed between the rigid metal framework and at least the outer wall of the panels. The panels are fixed to the frame by screws passing through an edge of the outer wall of the panels as well as the insulating joint. In this way, the fixing of the panels is done without causing the formation of any thermal bridge, the insulating plastic seal being interposed between the outer wall of the panel and the frame which is subjected, for its part, to the conditions of internal temperatures of the appliance.

Le joint isolant peut être fixé par serrage sur le pourtour des parois extérieure et intérieure des panneaux et présenter éventuellement au moins une lèvre souple capable d'entrer en contact avec une face de l'ossature.The insulating joint can be fixed by clamping on the periphery of the outer and inner walls of the panels and optionally have at least one flexible lip capable of coming into contact with one face of the framework.

Le joint isolant peut également, en variante, être simplement en partie serré entre deux rebords périphériques des parois respectives des panneaux.The insulating joint can also, as a variant, be simply partially clamped between two peripheral edges of the respective walls of the panels.

Dans un autre mode de réalisation, la paroi intérieure des panneaux présente un rebord périphérique directement fixé par des vis sur l'ossature métallique.In another embodiment, the interior wall of the panels has a peripheral rim directly fixed by screws to the metal framework.

Les portions de l'ossature qui ne sont pas recouvertes par la paroi extérieure des panneaux sont en outre recouvertes par des éléments supplémentaires entrant en contact avec l'ossature par l'intermédiaire d'une matière isolante. De cette manière, aucune portion de l'ossature métallique faisant face à l'air ambiant extérieur ne se trouve exposée à la température de l'air ambiant. On évite ainsi tout risque de condensation de l'humidité contenue dans l'air se trouvant à l'extérieur de l'appareil et ce, malgré l'exposition directe des faces internes de l'ossature métallique à l'air se trouvant à l'intérieur de l'appareil.The portions of the framework which are not covered by the external wall of the panels are also covered by additional elements coming into contact with the framework via an insulating material. In this way, no portion of the metal framework facing the outside ambient air is exposed to the temperature of the ambient air. This avoids any risk of condensation of the moisture contained in the air outside the device, despite the direct exposure of the internal faces of the metal frame to the air at the inside the appliance.

Dans un mode de réalisation préféré de l'invention, l'ossature est constituée par des profilés métalliques en acier ou en aluminium. Les profilés peuvent avoir une section angulaire et présenter une excroissance formant logement, permettant la fixation d'un cache extérieur lui-même réalisé en matière plastique isolante. Des baguettes, capables de dissimuler les vis de fixation des panneaux, peuvent être montées entre le cache extérieur en matière plastique précité et la paroi extérieure d'un panneau. L'ensemble de ces dispositions réalise une couverture complète de l'ossature en direction de l'extérieur, évitant ainsi, comme il a été indiqué, toute condensation externe.In a preferred embodiment of the invention, the framework is formed by metal sections of steel or aluminum. The profiles may have an angular section and have a protrusion forming a housing, allowing the fixing of an outer cover itself made of insulating plastic. Rods, capable of concealing the screws for fixing the panels, can be mounted between the outer plastic cover mentioned above and the outer wall of a panel. All of these provisions provide coverage complete the framework towards the outside, thus avoiding, as has been indicated, any external condensation.

Les baguettes peuvent avantageusement être fixées par serrage dans une gorge appropriée pratiquée dans le cache extérieur. Les baguettes, de préférence souples, peuvent également présenter une lèvre d'étanchéité venant s'appuyer contre la paroi extérieure du panneau.The rods can advantageously be fixed by clamping in a suitable groove made in the outer cover. The rods, preferably flexible, may also have a sealing lip which bears against the external wall of the panel.

Dans un mode de réalisation particulièrement adapté à l'utilisation de panneaux de grande épaisseur, un joint d'étanchéité supplémentaire est monté entre la paroi intérieure du panneau et une face de l'ossature.In an embodiment particularly suitable for the use of very thick panels, an additional seal is mounted between the inner wall of the panel and one face of the frame.

Dans un autre mode de réalisation, un cache extérieur métallique est fixé par des vis dans l'angle des profilés, des joints isolants étant disposés entre le cache et l'ossature métallique.In another embodiment, a metal outer cover is fixed by screws in the corner of the profiles, insulating joints being arranged between the cover and the metal frame.

Le cache métallique présente de préférence au moins une bordure latérale capable de dissimuler les vis de fixation des panneaux et venant en contact avec la paroi extérieure des panneaux.The metal cover preferably has at least one lateral border capable of concealing the screws for fixing the panels and coming into contact with the external wall of the panels.

Dans tous les cas, les profilés peuvent avantageusement présenter une prolongation pouvant servir de face d'appui pour l'appareil. De plus, les profilés présentent de préférence, sur leur face interne, des glissières d'ancrage pour la fixation d'organes internes de l'appareil.In all cases, the profiles can advantageously have an extension which can serve as a bearing face for the device. In addition, the profiles preferably have, on their internal face, anchoring slides for fixing internal organs of the device.

L'invention sera mieux comprise à l'étude de quelques modes de réalisation particuliers décrits à titre d'exemples nullement limitatifs et illustrés par les dessins annexés, sur lesquels :

  • la figure 1 est une vue en coupe d'un élément d'ossature et d'une partie de panneau d'un appareil de traitement de l'air, selon l'invention; et
  • les figures 2 à 4 sont des vues en coupe analogues de différentes variantes de réalisation.
The invention will be better understood from the study of a few particular embodiments described by way of non-limiting examples and illustrated by the appended drawings, in which:
  • Figure 1 is a sectional view of a frame member and a panel portion of an air treatment apparatus according to the invention; and
  • Figures 2 to 4 are similar sectional views of different embodiments.

Tel qu'il est illustré sur la figure 1, le bâti de l'appareil de traitement de l'air de l'invention comprend une ossature métallique 1 se présentant sous la forme d'un profilé réalisé dans l'exemple illustré en alluminium filé. L'ossature 1 qui définit les arêtes du volume occupé par l'appareil, permet la fixation de panneaux isolants 2, d'un cache extérieur en matière plastique 3 et d'une baguette isolante 4.As illustrated in Figure 1, the frame of the air treatment apparatus of the invention comprises a metal frame 1 in the form of a profile produced in the example illustrated in spun aluminum . The frame 1 which defines the edges of the volume occupied by the device, allows the fixing of insulating panels 2, an external plastic cover 3 and an insulating strip 4.

On notera que l'ossature de l'appareil comprend une pluralité de profilés 1 droits, assemblés par des pièces de coin en aluminium moulé, non représentées sur les figures. On peut également utiliser de telles pièces réalisées en acier moulé ou par mécano-soudure, en tôle épaisse pliée ou emboutie, ces pièces pouvant lier, par exemple, trois profilés orthogonaux de l'ossature. On comprendra que, dans un autre mode de réalisation, il soit également possible de lier entre eux les profilés par soudure directe.It will be noted that the framework of the device comprises a plurality of straight sections 1, assembled by molded aluminum corner pieces, not shown in the figures. It is also possible to use such parts made of cast steel or by mechanical welding, of thick folded or stamped sheet metal, these parts being able to link, for example, three orthogonal sections of the framework. It will be understood that, in another embodiment, it is also possible to link the profiles together by direct welding.

Les panneaux 2 comprennent une paroi mince extérieure 5 qui est constituée, par exemple, par une tôle emboutie en acier galvanisé, comportant sur son pourtour un rebord 6. Les panneaux 2 comportent, par ailleurs, une paroi mince intérieure 7 qui peut être également constituée par une tôle en acier galvanisé. Les deux parois 5 et 7 ensèrent une âme 8 en matériau isolant. Un joint isolant 9, réalisé par exemple en matière plastique, permet le montage étanche à l'air du panneau 2 sur le profilé 1 de l'ossature. A cet effet, le joint 9 constitué sous la forme d'un profilé de matière plastique, comporte une lèvre souple 10 venue de moulage, capable d'entrer en contact avec une face 11 du profilé 1. On notera que la lèvre d'étanchéité 10 est placée le plus près possible de la face intérieure de l'appareil qui est définie par la paroi intérieure 7 du panneau 2, afin de limiter au maximum les espaces devant être décontaminés lors d'un nettoyage de la partie intérieure de l'appareil. Le joint isolant 9 présente une première gorge 12 à l'intérieur de laquelle peut pénétrer la bordure de la paroi intérieure 7 et une deuxième gorge 13 à l'intérieur de laquelle vient pénétrer la bordure 6 de la paroi extérieure 5 du panneau 2. La fixation du panneau 2 se fait par une pluralité de vis 14 qui traversent des orifices pratiqués dans le joint 9 à l'endroit de la gorge 13, dans le rebord 6 et dans la paroi du profilé 1. Les vis 14 utilisées peuvent également être du type vis autoforeuse autorisant ainsi, de manière simple, la pose d'un nombre important de telles vis, permettant d'assurer une portée régulière du panneau 2 contre le profilé 1. Lors du serrage des vis 14, on comprend que la tôle métallique de la paroi extérieure 5 se trouve serrée contre le profilé 1 avec interposition du joint d'étanchéité 9, limitant ainsi au maximum les fuites thermiques à l'endroit de la fixation des panneaux 2.The panels 2 comprise an outer thin wall 5 which is constituted, for example, by a pressed sheet of galvanized steel, having on its periphery a flange 6. The panels 2 also comprise an inner thin wall 7 which can also be constituted by a galvanized steel sheet. The two walls 5 and 7 enclose a core 8 of insulating material. An insulating seal 9, made for example of plastic, allows the airtight mounting of the panel 2 on the profile 1 of the frame. To this end, the seal 9 formed in the form of a plastic profile, comprises a flexible lip 10 molded, capable of coming into contact with a face 11 of the profile 1. It will be noted that the sealing lip 10 is placed as close as possible to the inner face of the device which is defined by the interior wall 7 of the panel 2, in order to limit as much as possible the spaces which have to be decontaminated during cleaning of the interior part of the device. The insulating joint 9 has a first groove 12 inside which the edge of the interior wall 7 can penetrate and a second groove 13 inside which the edge 6 of the exterior wall 5 of the panel 2 penetrates. panel 2 is fixed by a plurality of screws 14 which pass through holes made in the joint 9 at the location of the groove 13, in the flange 6 and in the wall of the profile 1. The screws 14 used can also be of the self-drilling screw type thus authorizing, in a simple manner, the installation of a large number of such screws, making it possible to ensure a regular reach of the panel 2 against the profile 1. When tightening the screws 14, it is understood that the metal sheet of the outer wall 5 is clamped against the profile 1 with the interposition of the seal 9, thus limiting thermal leakage as far as possible at the location of the fastening of the panels 2.

Le montage est complété par le cache extérieur 3 et la baguette d'étanchéité 4. Le cache extérieur 3 réalisé également en matière plastique, est fixé par clipsage d'une nervure longitudinale 15 à l'intérieur d'un logement 16 constitué dans une excroissance 17 à l'angle du profilé 1, le logement 16 pouvant comporter des stries qui améliorent la fixation du cache extérieur 3.The assembly is completed by the outer cover 3 and the sealing strip 4. The outer cover 3 also made of plastic, is fixed by clipping a longitudinal rib 15 inside a housing 16 formed in a protrusion 17 at the corner of the profile 1, the housing 16 possibly having grooves which improve the fixing of the outer cover 3.

Le cache extérieur 3 présente deux gorges 18 permettant le montage des baguettes d'étanchéité 4. Les baguettes 4 réalisées de préférence en matière plastique souple, présentent un côté 19 pouvant être introduit dans la gorge 18 et viennent s'appuyer élastiquement par leur côté opposé 20 contre la paroi extérieure 5 du panneau 2 dans sa portion frontale 21.The outer cover 3 has two grooves 18 allowing the mounting of the sealing strips 4. The strips 4 preferably made of flexible plastic material, have a side 19 which can be introduced into the groove 18 and come to bear elastically on their opposite side 20 against the outer wall 5 of the panel 2 in its front portion 21.

Comme on peut le voir sur la figure 1, la totalité de la surface extérieure du profilé 1 se trouve ainsi recouverte par un matériau isolant ou par un élément qui est fixé au profilé par l'intermédiaire d'un matériau isolant. Aucune condensation ne peut donc intervenir au contact avec l'air extérieur.As can be seen in Figure 1, the entire outer surface of the profile 1 is thus covered by an insulating material or by an element which is fixed to the profile by means of an insulating material. No condensation can therefore occur on contact with the outside air.

La partie intérieure du profilé 1 soumise aux conditions de température intérieures de l'appareil, présente en outre deux rainures en forme de T référencées 22 et 23 qui constituent des glissières d'ancrage pour la fixation d'organes internes de l'appareil.The inner part of the profile 1 subject to the internal temperature conditions of the device, further has two T-shaped grooves referenced 22 and 23 which constitute anchor slides for fixing internal organs of the device.

Les deux faces planes orthogonales 4 et 25 disposées en bout de l'excroissance 17, comportant le logement 16, peuvent servir de faces d'appui pour le cache extérieur en matière plastique 3 sur le profilé 1 et supporter ainsi le poids de l'appareil sur le sol.The two orthogonal flat faces 4 and 25 arranged at the end of the protrusion 17, comprising the housing 16, can serve as bearing faces for the external plastic cover 3 on the profile 1 and thus support the weight of the device On the ground.

Le mode de réalisation illustré sur la figure 2, sur laquelle les pièces identiques ou similaires portent les mêmes références, se différencie du mode de réalisation précédent uniquement par le fait que le panneau 2 utilisé est plus épais. Dans ces conditions, la paroi intérieure 7 comprend un décrochement 26 et une bordure 27, laquelle permet, comme dans le mode de réalisation précédent, la fixation du joint 9 muni de sa lèvre d'étanchéité 10. Dans ce mode de réalisation, cependant, un joint d'étanchéité supplémentaire 28 est monté entre le rebord 26 de la paroi intérieure 7 et une prolongation de la face frontale du profilé 1. Le profilé 1, quant à lui, est de plus grande dimension pour pouvoir recevoir les panneaux 2 de plus grande épaisseur et comporte donc des nervures de renforcement interne 29. La portion d'angle du profilé 1, référencée 30 dans son ensemble, présente des surfaces orthogonales 24 et 25 servant comme précédemment d'appui au cache extérieur 3 et se poursuivant sous la forme du logement 16.The embodiment illustrated in Figure 2, in which identical or similar parts have the same references, differs from the previous embodiment only by the fact that the panel 2 used is thicker. Under these conditions, the interior wall 7 comprises a recess 26 and an edge 27, which allows, as in the previous embodiment, the fixing of the seal 9 provided with its sealing lip 10. In this embodiment, however, an additional seal 28 is mounted between the rim 26 of the inner wall 7 and an extension of the front face of the profile 1. The profile 1, in turn, is larger in order to accommodate the panels 2 more very thick and therefore has internal reinforcement ribs 29. The corner portion of the profile 1, referenced 30 as a whole, has orthogonal surfaces 24 and 25 serving as previously to support the outer cover 3 and continuing in the form of the housing 16.

Le mode de réalisation illustré sur la figure 3, sur laquelle les pièces identiques ou similaires portent les mêmes références, se différencie des modes de réalisation précédents essentiellement par la structure et la disposition du joint isolant. Dans ce mode de réalisation, en effet, le joint isolant 31 réalisé par exemple en caoutchouc néoprène muni d'une couche adhésive, se présente sous la forme d'une bande interposée en partie entre la bordure 6 de la paroi extérieure 5 du panneau 2 et la paroi correspondante de l'ossature métallique 1, en étant traversé par les vis de fixation 14. Une autre partie du joint isolant 31 est, quant à elle, serrée entre la bordure 6 de la paroi extérieure 5 et une bordure 32 de la paroi intérieure 7 du panneau 2, la bordure 32 n'étant pas, contrairement à ce qui est le cas de la bordure 6, traversée par les vis de fixation 14.The embodiment illustrated in FIG. 3, in which the identical or similar parts bear the same references, differs from the preceding embodiments essentially by the structure and the arrangement of the insulating joint. In this embodiment, in fact, the insulating seal 31 made for example of neoprene rubber provided with an adhesive layer, is in the form of a strip interposed partly between the edge 6 of the outer wall 5 of the panel 2 and the corresponding wall of the metal frame 1, being crossed by the fixing screws 14. Another part of the insulating joint 31 is, for its part, clamped between the edge 6 of the outer wall 5 and an edge 32 of the inner wall 7 of the panel 2, the edge 32 not being, unlike what is the case of the edge 6, crossed by the fixing screws 14.

Comme dans les modes de réalisation précédents, on comprend que l'on obtient ainsi une parfaite isolation entre la partie extérieure constituée par la paroi 5 et l'intérieur de l'appareil constitué par l'ossature métallique 1 et la paroi intérieure 7. Dans ce mode de réalisation, on retrouve en outre le cache 3 en matière plastique monté dans l'angle du profilé 1, ainsi que la baguette isolante 4.As in the previous embodiments, it is understood that a perfect insulation is thus obtained between the exterior part constituted by the wall 5 and the interior of the apparatus constituted by the metal frame 1 and the interior wall 7. In This embodiment also includes the plastic cover 3 mounted in the corner of the profile 1, as well as the insulating strip 4.

La variante illustrée sur la figure 4 sur laquelle les pièces identiques ou analogues portent les mêmes références, se différencie du mode de réalisation de la figure 3, principalement par le fait que le panneau 2 est plus épais, comme c'était le cas dans la variante illustrée sur la figure 2. Dans ce mode de réalisation, le joint isolant 31 a la même structure que dans le mode de réalisation de la figure 2. Il est constitué par une bande de caoutchouc néoprène collée par un revêtement adhésif sur la face en regard de l'ossature métallique 1. Dans ce mode de réalisation, compte tenu de l'épaisseur du panneau isolant 2, la paroi intérieure 7 est fixée directement sur l'ossature métallique 1 par des vis 33 qui traversent la bordure 32. Dans ce mode de réalisation également, on retrouve un cache extérieur 3 en matière plastique et une baguette isolante 4.The variant illustrated in FIG. 4 in which the identical or similar parts bear the same references, differs from the embodiment in FIG. 3, mainly by the fact that the panel 2 is thicker, as was the case in the variant illustrated in FIG. 2. In this mode of embodiment, the insulating joint 31 has the same structure as in the embodiment of FIG. 2. It consists of a strip of neoprene rubber bonded by an adhesive coating on the opposite face of the metal framework 1. In this mode embodiment, taking into account the thickness of the insulating panel 2, the inner wall 7 is fixed directly to the metal frame 1 by screws 33 which pass through the edge 32. In this embodiment also, there is an external cover 3 made of plastic and an insulating strip 4.

Dans certaines applications, il est cependant nécessaire de prévoir un cache extérieur métallique à la place du cache extérieur en matière plastique 3. Les figures 5 et 6 illustrent une modification des modes de réalisation respectifs des figures 3 et 4, dans laquelle le cache extérieur 3 et la baguette isolante 4 ont été remplacés par un cache métallique 34 réalisé sous la forme de deux profilés accolés 34a, 34b réalisés par exemple en aluminium. Le cache métallique 34 est monté comme le cache extérieur 3 à l'angle de l'ossature métallique 1, en prenant appui sur l'excroissance 17. Le montage se fait cependant sans utiliser cette fois le logement 16 qui subsiste sur l'ossature métallique 1 pour le cas où l'on préfèrerait monter comme précédemment un cache en matière plastique 3. Un joint isolant 35, réalisé par exemple en caoutchouc néoprène muni d'un revêtement adhésif, vient coiffer l'excroissance 17 et se trouve serré entre celle-ci et l'angle du cache métallique 34. Chaque profilé métallique 34a, 34b présente une nervure 36 disposée perpendiculairement au plan du panneau isolant 2 et capable de venir en contact avec la bordure latérale du joint isolant 31. La fixation des profilés 34a, 34b se fait par des vis de serrage 37 qui pénètrent dans les parois de l'ossature métallique 1.In certain applications, it is however necessary to provide a metal external cover in place of the external plastic cover 3. Figures 5 and 6 illustrate a modification of the respective embodiments of Figures 3 and 4, in which the external cover 3 and the insulating strip 4 have been replaced by a metal cover 34 produced in the form of two joined profiles 34a, 34b made for example of aluminum. The metal cover 34 is mounted like the external cover 3 at the corner of the metal frame 1, by resting on the protrusion 17. The assembly is however done without using this time the housing 16 which remains on the metal frame 1 for the case where it would be preferable to mount a plastic cover as before 3. An insulating seal 35, made for example of neoprene rubber provided with an adhesive coating, covers the protrusion 17 and is clamped between it ci and the angle of the metal cover 34. Each metal section 34a, 34b has a rib 36 arranged perpendicular to the plane of the insulating panel 2 and capable of coming into contact with the lateral edge of the insulating joint 31. The fixing of the sections 34a, 34b is done by clamping screws 37 which penetrate into the metal frame walls 1.

Chaque profilé 34a, 34b présente en outre une bordure latérale 38 munie d'un rebord 39, qui vient en contact avec la paroi extérieur 5 du panneau 2 et permet en outre de dissimuler les vis de fixation 14 remplaçant à cet égard les baguettes isolantes 4 des modes de réalisation illustrés sur les figures 1 à 4.Each profile 34a, 34b further has a side edge 38 provided with a flange 39, which comes into contact with the outer wall 5 of the panel 2 and also makes it possible to conceal the fixing screws 14 replacing in this respect the insulating strips 4 embodiments illustrated in FIGS. 1 to 4.

La structure du bâti de l'appareil de traitement d'air de l'invention permet d'obtenir une excellente étanchéité à l'air et une absence de continuité métallique entre le milieu intérieur et le milieu extérieur. La fixation des panneaux se fait aisément par des vis extérieures facilement accessibles à l'utilisateur par simple déformation du matériau souple qui constitue les baguettes d'étanchéité 4 ou éventuellement par démontage de ces dernières ou du cache métallique d'angle. L'existence de ces baguettes ou des joints isolants 31 et 35 permet d'éviter tout risque de condensation externe en combinaison avec le montage particulier des panneaux et les caches extérieurs 3 ou 34.The structure of the frame of the air handling device of the invention makes it possible to obtain an excellent airtightness and an absence of metallic continuity between the interior and the exterior environment. The panels are easily fixed by external screws which are easily accessible to the user by simple deformation of the flexible material which constitutes the sealing strips 4 or possibly by dismantling the latter or the metal corner cover. The existence of these rods or of the insulating joints 31 and 35 makes it possible to avoid any risk of external condensation in combination with the particular mounting of the panels and the external covers 3 or 34.

De plus, la structure du profilé 1 permet l'accrochage facile des composants internes sans perçage de l'ossature, par exemple au moyen d'écrous prisonniers dans les glissières d'ancrage 22 et 23.In addition, the structure of the profile 1 allows easy attachment of the internal components without drilling the frame, for example by means of captive nuts in the anchor slides 22 and 23.
