Description

L'invention concerne essentiellement un dispositif de compression d'air.The invention relates essentially to a compression device air.

ETAT DE LA TECHNIQUE ANTERIEURESTATE OF THE PRIOR ART

De nombreux dispositifs de compression d'air sont antérieurement connus. La plupart sont complexes et nécessitent une consommation en énergie importante.Many air compression devices are previously known. Most are complex and require energy consumption important.

D'autre part, dans le cadre de la régulation de la température dans un local au moyen d'un flux d'air, les dispositifs antérieurs sont basés généralement sur l'emploi d'un mélange de flux d'air à des températures différentes pour régler la température à la température souhaitée, à pression constante.On the other hand, as part of the temperature regulation in a local by means of an air flow, the prior devices are generally based on the use of a mixture of air flows at different temperatures to regulate the temperature at the desired temperature, at constant pressure.

Ainsi, par exemple, le document DE-A-36 44 590 décrit notamment en relation aux figures 12 à 14 un mode de réalisation d'un appareil de climatisation d'air d'un local comprenant un diffuseur d'air 55 d'induction à débit variable par la présence d'un dispositif 57 de fermeture partielle de l'ouverture 21 de sortie, qui réalise une variation de débit mais en utilisant la même pression que la pression entrante. Il s'agit donc d'un système classique où la pression de sortie est essentiellement identique à la pression entrante et de l'ouverture complète à la fermeture complète, la pression de sortie de l'air reste inchangée, de sorte que la longueur du jet d'air évolue suivant la valeur de l'ouverture de sortie utile 21.Thus, for example, document DE-A-36 44 590 describes in particular in relation to FIGS. 12 to 14, an embodiment of an apparatus for air conditioning of a room comprising an air diffuser 55 with flow induction variable by the presence of a device 57 for partially closing the opening 21 outlet, which performs a flow variation but using the same pressure as incoming pressure. It is therefore a classic system where the outlet pressure is essentially identical to the incoming pressure and from the complete opening to the complete closure, the air outlet pressure remains unchanged, so that the length of the air jet changes according to the value of the useful outlet opening 21.

Le document US 2,959,359 concerne une buse à réglage de débit qui fonctionne selon le même principe, particulièrement décrite pour atomiser des liquides.Document US 2,959,359 relates to a nozzle with flow adjustment which works on the same principle, particularly described for atomizing liquids.

Encore, le document US 3,776,470 décrit un dispositif de buse à ouverture variable pour le transport de divers fluides pouvant comporter des particules solides écoulables qui fonctionnent encore selon le même principe que les documents précédents, sans dispositif d'obstruction à l'amont ce qui serait d'ailleurs contraire au principe de circulation, en particulier de particules solides écoulables.Again, document US 3,776,470 describes a nozzle device with variable opening for the transport of various fluids which may include solid flowable particles which still operate on the same principle as previous documents, with no obstruction upstream which would be moreover contrary to the principle of circulation, in particular of solid particles flowable.

Selon un premier aspect, la présente invention concerne un appareil permettant d'obtenir un jet de fluide de préférence à portée constante comprenant un conduit de confinement dudit fluide, ouvert aux deux extrémités amont et aval, pourvu à son extrémité aval d'au moins un dispositif de compression dudit fluide compressible comprenant une enveloppe déformable entre une section d'ouverture maximale et une section d'ouverture minimale, caractérisé en ce qu'il comprend, à son extrémité amont, au moins un organe prévu pour régler la perte de charge du fluide entrant en permettant ainsi d'augmenter la pression de l'air traversant l'enveloppe depuis une pression minimale pour l'ouverture maximale à une pression maximale pour l'ouverture minimale, fournissant ainsi une pression du fluide à la sortie de l'appareil variable à partir d'un flux incident à pression sensiblement constante.According to a first aspect, the present invention relates to an apparatus making it possible to obtain a jet of fluid preferably at constant range comprising a conduit for confining said fluid, open at both upstream and downstream ends, provided at its downstream end with at least one device for compressing said fluid compressible comprising a deformable envelope between an opening section maximum and a minimum opening section, characterized in that it comprises, at its upstream end, at least one member intended to regulate the loss of charge of incoming fluid thereby increasing air pressure crossing the envelope from a minimum pressure for the maximum opening at maximum pressure for minimum opening, thus providing pressure of fluid at the outlet of the variable device from an incident pressure flow substantially constant.

Autrement dit, l'invention permet de réaliser un transfert d'énergie de la partie amont à la partie avale grâce à la présence d'au moins un organe prévu pour régler la perte de charge du flux entrant. On comprend qu'à l'ouverture maximale en aval, le débit est maximal et la perte de charge est maximale, de sorte que la pression du fluide sortant de l'appareil de l'invention est minimale, c'est-à-dire très différente de la pression du flux entrant tandis que lorsque l'ouverture est presque fermée, le débit sortant est minimal, de sorte que la perte de charge dans le dispositif de réglage de perte de charge tend vers zéro, ce qui réalise un transfert de pression de ce dispositif de perte de charge à la sortie de l'appareil et la pression de sortie est à ce moment là maximale.In other words, the invention allows energy transfer from the upstream part to the downstream part thanks to the presence of at least one member provided to adjust the pressure drop of the incoming flow. We understand that at the opening maximum downstream, the flow is maximum and the pressure drop is maximum, from so that the pressure of the fluid leaving the apparatus of the invention is minimal, that is to say very different from the pressure of the incoming flow while when the opening is almost closed, the outflow is minimal, so that the loss load in the pressure drop adjuster tends to zero, which transfers pressure from this pressure drop device to the outlet of the device and the outlet pressure is then maximum.

On peut ainsi construire un appareil qui, par exemple, pour une réduction de débit de 50 % maintient un débit aval inchangé (ce qui est tout à fait surprenant et remarquable).We can thus build a device which, for example, for a 50% flow reduction maintains a downstream flow unchanged (which is quite surprising and remarkable).

En référence à la figure 1, on a représenté une vue en coupe longitudinale d'un dispositif, représenté par le numéro de référence général 10, de compression d'un fluide compressible 12, ici incorporé dans un appareil, représenté par le numéro de référence général 100, permettant d'obtenir un jet de fluide à portée sensiblement constante, grâce à la génération d'une pression variable en sortie à partir d'un flux incident à pression sensiblement constante, cette variation de pression étant obtenue grâce à la présence d'au moins un organe 120 de réglage de perte de charge disposé en amont et qui sera décrit plus précisément plus loin. En outre, on notera que dans le cadre de l'invention, les différents dispositifs ou organes de l'appareil 100 sont essentiellement coaxialement alignés. Referring to Figure 1, there is shown a sectional view longitudinal of a device, represented by the general reference number 10, of compression of a compressible fluid 12, here incorporated in an apparatus, represented by the general reference number 100, making it possible to obtain a jet of fluid at substantially constant range, thanks to the generation of pressure variable output from an incident flow at substantially constant pressure, this pressure variation being obtained thanks to the presence of at least one member 120 pressure drop adjustment arranged upstream and which will be described more precisely further. In addition, it will be noted that in the context of the invention, the different devices or organs of the apparatus 100 are essentially coaxially aligned.

Le dispositif 10 selon l'invention de compression d'un fluide compressible 12 est caractérisé en ce qu'il comprend une enveloppe 20 déformable, ici de révolution, entre une section d'ouverture maximale, représentée à la figure 1, en partie en trait fantôme à la figure 2, en trait fantôme à la figure 3 et en trait plein à la figure 4, et une section d'ouverture minimale, représentée en trait plein à la figure 2, à la figure 3 et à la figure 6.The device 10 according to the invention for compressing a fluid compressible 12 is characterized in that it comprises an envelope 20 deformable, here of revolution, between a maximum opening section, shown in Figure 1, partly in phantom in Figure 2, in phantom in Figure 3 and in solid lines in FIG. 4, and a minimum opening section, represented by solid line in Figure 2, Figure 3 and Figure 6.

Cette enveloppe 20 déformable permet ainsi d'augmenter la pression de l'air traversant ladite enveloppe depuis une pression minimale pour l'ouverture maximale, à une pression maximale, pour l'ouverture minimale, comme cela est bien compréhensible à un homme de l'art.This deformable envelope 20 thus makes it possible to increase the pressure air passing through said envelope from a minimum pressure for opening maximum, at maximum pressure, for minimum opening, as is understandable to a person skilled in the art.

Selon un mode de réalisation avantageux de l'invention, l'enveloppe 20 déformable précitée présente pour sa section d'ouverture maximale, représentée aux figures 1, 4 et 7, une section sensiblement cylindrique, ce qui est également clairement visible à ces figures.According to an advantageous embodiment of the invention, the envelope 20 aforementioned deformable present for its maximum opening section, shown in Figures 1, 4 and 7, a substantially cylindrical section, which is also clearly visible in these figures.

Selon un autre mode de réalisation de l'invention, l'enveloppe 20 présente, pour l'ouverture maximale, une section sensiblement aplatie.According to another embodiment of the invention, the envelope 20 has, for the maximum opening, a substantially flattened section.

Selon un autre mode de réalisation de l'invention, le dispositif 10 est caractérisé en ce qu'il comprend des moyens 30 de variation de la section de l'enveloppe 20 déformable précitée.According to another embodiment of the invention, the device 10 is characterized in that it comprises means 30 for varying the section of the aforementioned deformable envelope 20.

Selon une variante de réalisation avantageuse, les moyens 30 de variation de la section de l'enveloppe 20 sont commandés par un organe (40) de commande extérieure à l'enveloppe 20, n'interférant pas avec la section d'ouverture de l'enveloppe 20 déformable.According to an advantageous alternative embodiment, the means 30 of variation of the section of the envelope 20 are controlled by a member (40) of control outside the envelope 20, not interfering with the section opening of the deformable envelope 20.

Cet organe de commande 40, visible au moins aux figures 2 et 3, peut par exemple comprendre un galet 42, par exemple de forme ellipsoïdale, définissant un grand diamètre D et un petit diamètre d, clairement visible à la figure 2, monté en rotation selon un axe de rotation 44, disposé essentiellement perpendiculairement au plan défini par le galet ellipsoïdal 42 et qui est commandé par des moyens de commande en rotation de type classique, bien connus à l'homme de l'art, et qui ne sont donc pas représentés ici pour une meilleure compréhension des figures.This control member 40, visible at least in Figures 2 and 3, can for example comprising a roller 42, for example of ellipsoidal shape, defining a large diameter D and a small diameter d, clearly visible at the Figure 2, mounted in rotation along an axis of rotation 44, arranged essentially perpendicular to the plane defined by the ellipsoidal roller 42 and which is controlled by conventional type rotation control means, well known in those skilled in the art, and who are therefore not represented here for better understanding of the figures.

Selon une autre variante de réalisation avantageuse de l'invention, le dispositif 10 est caractérisé en ce que l'enveloppe 20 déformable précitée comprend une membrane 22, qui à l'état non déformé, représenté aux figures 1, 4, 7 et 8, présente une forme essentiellement cylindrique, par exemple réalisée en caoutchouc, élastomère ou matériaux similaires. According to another advantageous alternative embodiment of the invention, the device 10 is characterized in that the above deformable envelope 20 comprises a membrane 22, which in the non-deformed state, represented in FIGS. 1, 4, 7 and 8, has an essentially cylindrical shape, for example made of rubber, elastomer or similar materials.

Selon un mode de réalisation particulièrement avantageux de l'invention, les moyens 30 de variation de la section de l'enveloppe 20 déformable précitée comprennent au moins deux éléments d'aplatissement, respectivement 32, 34, clairement visibles aux figures, disposés sensiblement diamétralement opposés par rapport à l'axe X-X de symétrie, en particulier représenté à la figure 2, de l'enveloppe 20 de révolution précitée.According to a particularly advantageous embodiment of the invention, the means 30 for varying the section of the deformable envelope 20 mentioned above comprise at least two flattening elements, respectively 32, 34, clearly visible in the figures, arranged substantially diametrically opposite with respect to the axis X-X of symmetry, in particular represented in FIG. 2, of the envelope 20 of the aforementioned revolution.

Selon une variante de réalisation actuellement préférée, les deux éléments 32, 34 comprennent ici une lame sensiblement plane montée en rotation selon un axe de rotation 36, 38, clairement représenté à la figure 2, sensiblement perpendiculaire à l'axe de symétrie X-X de l'enveloppe de révolution 20.According to an embodiment which is currently preferred, the two elements 32, 34 here comprise a substantially planar blade mounted in rotation along an axis of rotation 36, 38, clearly shown in Figure 2, substantially perpendicular to the axis of symmetry X-X of the envelope of revolution 20.

Avantageusement, les lames sensiblement planes comprennent vers l'extrémité libre de sortie du fluide au moins deux éléments 50, 52 formant cales d'épaisseur pré-déterminée disposés diamétralement opposés par rapport à l'enveloppe de révolution 20 précitée, de manière à venir en fin de course, fermer l'enveloppe de révolution 20 dans sa partie centrale, comme représenté en trait plein à la figure 2, à la figure 3, en ne laissant ainsi subsister aucun espace sur la distance définie par les éléments formant cales 50, 52, comme clairement visible à la figure 3, mais en laissant subsister deux zones ouvertes respectivement référencées Z1, Z2 à la figure 3, désaxées par rapport à l'axe X-X de symétrie de façon à obtenir un débit de fluide à une pression maximale. Naturellement, les éléments 50, 52 formant cales ne sont pas indispensables et ils peuvent être éliminés si l'on souhaite obtenir une fermeture complète de l'ouverture de sortie, comme cela est éventuellement avantageux dans certains systèmes de climatisation lorsque l'on souhaite isoler une pièce donnée.Advantageously, the substantially planar blades include towards the free end of the fluid outlet at least two elements 50, 52 forming shims of predetermined thickness arranged diametrically opposite with respect to the aforementioned envelope of revolution 20, so as to come to the end of its travel, close the envelope of revolution 20 in its central part, as shown in line full in Figure 2, in Figure 3, thus leaving no space remaining on the distance defined by the shim elements 50, 52, as clearly visible at Figure 3, but leaving two open areas respectively referenced Z1, Z2 in FIG. 3, off-axis with respect to the axis X-X of symmetry of so as to obtain a flow of fluid at maximum pressure. Naturally, elements 50, 52 forming shims are not essential and they can be eliminated if it is desired to obtain a complete closure of the outlet opening, as this is possibly advantageous in certain systems of air conditioning when you want to isolate a given room.

Selon un autre mode de réalisation de l'invention, l'enveloppe de révolution 20 précitée présente une longueur prédéterminée, qui peut avantageusement être d'environ au moins deux fois son diamètre.According to another embodiment of the invention, the envelope of revolution 20 above has a predetermined length, which can advantageously be about at least twice its diameter.

On peut également prévoir autour de l'enveloppe de révolution 20, la présence d'un élément de renforcement 54, représenté en particulier aux figures 4 à 6, éventuel, déformable, tel qu'une grille métallique, qui permet de limiter l'expansion de l'enveloppe de révolution 20, constituée en pratique par la membrane 22, lors du passage sous pression du fluide 12, à l'intérieur de celle-ci.It is also possible to provide around the envelope of revolution 20, the presence of a reinforcing element 54, shown in particular in FIGS. 4 to 6, possible, deformable, such as a metal grid, which makes it possible to limit the expansion of the envelope of revolution 20, constituted in practice by the membrane 22, during the passage under pressure of the fluid 12, inside the latter.

Naturellement, les moyens 30 de variation de la section de l'enveloppe 20, ici comprenant de préférence les éléments d'aplatissement 32, 34, sous forme de lames sensiblement planes, sont appliqués contre la surface de l'organe de commande 40, ici sous forme d'un galet 42, par des moyens de poussée unilatérale 60, tels que des ressorts 62, ou autres moyens équivalents ;Naturally, the means 30 for varying the section of the envelope 20, here preferably comprising the flattening elements 32, 34, in the form substantially planar blades are applied against the surface of the control 40, here in the form of a roller 42, by unilateral pushing means 60, such as springs 62, or other equivalent means;

On comprend ainsi qu'il est,très aisé selon l'invention de modifier la section d'ouverture de l'enveloppe déformable 20 par simple mise en rotation de l'organe de commande 40 en agissant sur l'axe de rotation 44, comme cela est aussi clairement visible en comparant les figures 8 et 9, respectivement d'ouverture maximale et d'ouverture minimale.It is thus understood that it is very easy according to the invention to modify the opening section of the deformable envelope 20 by simple rotation of the control member 40 by acting on the axis of rotation 44, as is also clearly visible by comparing Figures 8 and 9, respectively maximum opening and minimum opening.

Dans le cadre de l'application de ce dispositif de compression de fluide, à un appareil 100 à jet de fluide de préférence à portée sensiblement constante, ledit appareil est caractérisé selon l'invention en ce qu'il comprend un conduit 110 de confinement dudit fluide 12, ouvert aux deux extrémités amont 112 et aval 114, pourvu à son extrémité aval 114, d'au moins un dispositif 10, selon la présente invention tel que précédemment décrit.As part of the application of this compression device fluid, to an apparatus 100 with jet of fluid preferably with range substantially constant, said apparatus is characterized according to the invention in that it comprises a conduit 110 for confining said fluid 12, open at the two upstream ends 112 and downstream 114, provided at its downstream end 114, with at least one device 10, according to the present invention as previously described.

L'appareil 100 selon l'invention est, selon un mode de réalisation avantageux, caractérisé en ce qu'il comprend à son extrémité amont 112 au moins un organe 120 prévu pour régler la perte de charge du fluide entrant.The apparatus 100 according to the invention is, according to one embodiment advantageous, characterized in that it comprises at its upstream end 112 at least a member 120 provided for adjusting the pressure drop of the incoming fluid.

Selon un mode de réalisation actuellement préféré, cet organe 120 créant et réglant une perte de charge comprend au moins un cylindre, tel que 122, 124, 126, schématisé à la figure 1 et représenté plus précisément aux figures 8 et 9, subdivisé en une multitude de tubulures, telles que 130, que l'on voit bien aux figures 8 et 9, de diamètre prédéterminé de passage dudit fluide permettant ainsi d'obtenir une perte de charge prédéterminée, en augmentant la souplesse d'utilisation du dispositif 10 précité et la variation de pression en aval.According to a currently preferred embodiment, this member 120 creating and regulating a pressure drop comprises at least one cylinder, such as 122, 124, 126, shown diagrammatically in FIG. 1 and shown more precisely in FIGS. 8 and 9, subdivided into a multitude of tubes, such as 130, which can be clearly seen in the Figures 8 and 9, of predetermined diameter of passage of said fluid thus allowing to obtain a predetermined pressure drop, by increasing the flexibility of use of the aforementioned device 10 and the downstream pressure variation.

Avantageusement, l'appareil 100 selon l'invention est caractérisé en ce qu'il comprend en amont plusieurs organes de perte de charge, par exemple trois références 122, 124, 126, pouvant être embrochables, comme cela est bien compréhensible à un homme de l'art, de façon à augmenter la longueur totale des tubulures 130, en faisant ainsi varier la perte de charge, ce qui influe sur la valeur de la pression du fluide à la sortie de l'appareil 100, pour une pression sensiblement constante du flux incident entrant dans l'appareil.Advantageously, the apparatus 100 according to the invention is characterized in what it includes upstream several pressure drop members, for example three references 122, 124, 126, which can be plug-in, as is good understandable to a person skilled in the art, so as to increase the total length of the pipes 130, thereby varying the pressure drop, which influences the value of the fluid pressure at the outlet of the device 100, for a pressure substantially constant of the incident flow entering the device.

Selon un autre mode de réalisation avantageux de l'invention, la conduite de confinement précitée 110 présente, sur au moins une partie, une surface interne 140 de diamètre progressivement décroissant d'amont en aval, pour augmenter la vitesse de passage du fluide.According to another advantageous embodiment of the invention, the said containment pipe 110 has, on at least part, a internal surface 140 of progressively decreasing diameter from upstream to downstream, to increase the speed of passage of the fluid.

A la figure 9, on a représenté une modification possible de l'organe 120 de perte de charge, particulièrement intéressante dans le cadre de grandes installations, où l'on recherche un réglage précis de la perte de charge qui peut être altematif au réglage obtenu par le nombre de disques précités 122, 124, 126 et qui consiste à prévoir au moins un organe 132 d'obturation partielle de la section active de l'organe 120 de perte de charge, ici par exemple disposé en amont mais qui peut être aussi disposé en aval, cet organe 132 est avantageusement disposé en amont pour le caractère aisé de réglage et est monté déplaçable en translation sensiblement selon l'axe de symétrie de l'appareil 100 repéré X-X à la figure 9 en étant solidaire par exemple d'une tige filetée 133 coopérant avec un élément formant écrou 134 de position fixe. Cet organe 132 d'obturation partielle peut présenter un empâtement maximal ou diamètre D capable d'obturer au maximum environ 50 % de la surface d'entrée de la section S du conduit d'entrée 102 du flux, par exemple de l'air. Il peut être avantageux de profiler la partie amont de l'organe 132 d'obturation partielle, par exemple ici selon une forme tronconique de manière à créer le minimum de turbulences sur le flux amont entrant. On comprend que lorsque l'on visse l'organe 132 sur la vis 133, on rapproche ou éloigne l'organe 132 d'obturation partielle que l'on rend de plus en plus actif ou inversement de plus en plus inactif en fonction de la distance qui le sépare de la surface de l'organe du premier organe 122 de perte de charge. A l'extrême, lorsque cet organe 132 vient s'appliquer sur la surface du premier organe 122 de perte de charge, il obturera complètement les orifices 130 disposés à l'intérieur de son empâtement. Grâce à ce réglage, il est possible de faire varier le débit de 50 % et donc de régler la perte de charge d'une valeur de 1 à 4, comme cela est bien compréhensible à un homme de l'art.In Figure 9, there is shown a possible modification of the organ 120 pressure drop, particularly advantageous for large installations, where we are looking for a precise adjustment of the pressure drop which can be alternatively to the adjustment obtained by the number of aforementioned discs 122, 124, 126 and which consists in providing at least one member 132 for partially closing the section active of the pressure drop member 120, here for example arranged upstream but which can also be arranged downstream, this member 132 is advantageously arranged in upstream for easy adjustment and is mounted movable in translation substantially along the axis of symmetry of the device 100 marked X-X in Figure 9 in being integral for example with a threaded rod 133 cooperating with an element forming nut 134 of fixed position. This partial obturation member 132 can have a maximum impasto or diameter D capable of closing as much as possible about 50% of the inlet surface of section S of the inlet conduit 102 of the flow, for example air. It may be advantageous to profile the upstream part of the member 132 partial obturation, for example here in a frustoconical form so to create the minimum of turbulence on the upstream incoming flow. We understand that when the member 132 is screwed onto the screw 133, the member 132 is moved towards or away partial shutter which is made more and more active or vice versa more inactive depending on the distance from the surface of the organ of the first pressure drop member 122. In the extreme, when this organ 132 comes apply to the surface of the first pressure drop member 122, it will seal completely the orifices 130 arranged inside its impasto. Thanks to this adjustment, it is possible to vary the flow rate by 50% and therefore adjust the loss of charge worth 1 to 4, as is understandable to a man of art.

Dans le cadre de l'utilisation de l'appareil de l'invention 100 pour la climatisation d'au moins un local, celui-ci est caractérisé en ce qu'il comprend en outre un système 150 d'injection de fluide 152 à une température prédéterminée pour corriger la température ou l'humidité dudit local, disposé de préférence extérieurement à la conduite de confinement 110.In the context of the use of the apparatus of the invention 100 for the air conditioning of at least one room, this is characterized in that it comprises in addition to a fluid injection system 150 152 at a predetermined temperature to correct the temperature or humidity of said room, preferably arranged outside the containment pipe 110.

Selon une variante de réalisation avantageuse, le système 150 d'injection précité est disposé au voisinage de la sortie aval dudit fluide 12, comme représenté à la figure 1, de préférence de manière désaxée par rapport à l'axe X-X de l'enveloppe 20 de révolution, comme représenté à la figure 1.According to an advantageous alternative embodiment, the system 150 of the aforementioned injection is placed in the vicinity of the downstream outlet of said fluid 12, as shown in Figure 1, preferably offset from the axis X-X of the envelope 20 of revolution, as shown in FIG. 1.

Selon un mode de réalisation actuellement préféré, le système 150 d'injection comprend une conduite 154 d'injection complémentaire de fluide 152 dont le diamètre est d'environ deux à quatre fois inférieur au diamètre de l'enveloppe 20 de révolution précitée à l'état non déformé, représenté en particulier aux figures 4, 7 et 8.According to a currently preferred embodiment, the system 150 injection system includes a complementary fluid injection line 154 whose diameter is about two to four times less than the diameter of the aforementioned envelope 20 of revolution in the non-deformed state, shown in particular to Figures 4, 7 and 8.

Selon un autre mode de réalisation, qui peut être intéressant dans certains cas d'application, le système d'injection précité peut être disposé à l'intérieur de la tuyauterie de confinement 110, au voisinage de son extrémité amont.According to another embodiment, which can be interesting in certain application cases, the aforementioned injection system may be arranged to inside the containment piping 110, near its end upstream.

Selon un autre mode de réalisation avantageux de l'appareil selon l'invention 100, la tuyauterie de confinement 110 précitée peut elle-même être disposée à l'intérieur d'une gaine 160 d'alimentation en fluide dudit local.According to another advantageous embodiment of the apparatus according to invention 100, the aforementioned containment piping 110 may itself be disposed inside a sheath 160 for supplying fluid to said room.

Avantageusement, la tuyauterie de confinement 110 peut être disposée dans ladite gaine 160 au voisinage d'une entrée 162 d'admission de fluide 12a de puis ledit local, par une gaine appropriée d'admission 164, ladite admission étant de préférence réalisée par un moyen mécanique externe 166, tel qu'un ventilateur.Advantageously, the containment piping 110 can be arranged in said sheath 160 in the vicinity of a fluid inlet inlet 162 12a of then said room, by an appropriate intake duct 164, said admission being preferably performed by external mechanical means 166, such as a fan.

On comprend ainsi que le fluide précité est de préférence constitué par de l'air et ledit local comprend au moins une pièce d'un local industriel ou d'une habitation.It is thus understood that the aforementioned fluid is preferably constituted by air and said room comprises at least one room of an industrial room or a dwelling.

Ainsi, grâce à l'invention, il est possible de créer un jet de fluide, de préférence d'air, à efficacité sensiblement constante pour régler la puissance de chaud ou de froid d'un local en modifiant simplement le débit d'air par modification de la section d'ouverture aval d'un fluide admis à une pression sensiblement constante en amont.Thus, thanks to the invention, it is possible to create a jet of fluid, preferably air, with substantially constant efficiency to regulate the power of hot or cold of a room by simply modifying the air flow by modification of the downstream opening section of a fluid admitted to a pressure substantially constant upstream.

Par exemple, on sait que pour régler la température d'un local en été, il est d'usage de faire varier les débits d'air froid de 100 % à 25 %, et au-delà de cette valeur, le confort devient aléatoire, l'air froid à faible vitesse tombant sur les personnes en créant des courants gênants pour l'utilisateur, ceci même avec des bouches de soufflage de qualité ou des systèmes à induction traditionnelle.For example, we know that to adjust the temperature of a room in summer, it it is customary to vary the cold air flow rates from 100% to 25%, and beyond this value, comfort becomes random, cold air at low speed falling on the people creating currents that are annoying for the user, even with quality air outlets or traditional induction systems.

En hiver, on ne régule plus la puissance de chauffe par la réduction du débit d'air. Le débit est fixé à une valeur stable et un thermostat règle un débit d'eau chaude ou la puissance d'une batterie électrique.In winter, the heating power is no longer regulated by reducing the air flow. The flow is fixed at a stable value and a thermostat regulates a flow hot water or the power of an electric heater.

L'invention permet de réduire de 100 % à 25 % la puissance chaude ou froide en ne réduisant que faiblement ou pas plus de 25 % environ le débit aval.The invention makes it possible to reduce the hot power from 100% to 25% or cold by reducing only slightly or not more than about 25% the downstream flow.

En outre, les forts taux d'induction obtenus permettent de ne générer aucun courant d'air froid ou chaud à faible débit amont du fait que l'air soufflé est à une température voisine de la température du local, en amenant une amélioration de la trajectoire de l'air, qui se situe en dehors de la zone d'occupation, cette trajectoire étant sensiblement horizontale, quel que soit le débit, par augmentation de la pression.In addition, the high induction rates obtained do not generate no cold or hot air flow at low flow upstream because the supply air is at a temperature close to the room temperature, leading to an improvement of the air trajectory, which is outside the area of occupation, this trajectory being substantially horizontal, whatever the flow, by increase pressure.

Grâce à l'invention, on obtient le diagramme de débit d'air amont et de débit aval représenté à la figure 10, pour une pression de 290 Pascal du fluide entrant. On peut observer que si l'on passe d'un débit amont de 100 m3 par heure à 10 m3 par heure, le débit aval permettra d'obtenir un débit total, qui sera toujours supérieur à 100 m3 par heure, grâce à la réduction de la section de sortie du fluide 12 du dispositif 10 de compression selon l'invention, ce qui permet d'augmenter le taux d'induction, sous l'influence de trois facteurs, qui sont la montée de pression et vitesse sur la tête de sortie, à mesure que le débit diminue, jusqu'à l'obtention d'un quasi-doublement de la pression du fluide dans la sortie, la réduction du volume du jet d'air 12 comprimé à l'intérieur de la gaine 160, libère un espace pour l'air induit toujours plus grand et le maintien du périmètre de contact du jet d'air induit en raison de l'aplatissement de l'enveloppe 20 de révolution déformable précitée.Thanks to the invention, the diagram of upstream air flow and downstream flow shown in FIG. 10 is obtained, for a pressure of 290 Pascal of the incoming fluid. We can observe that if we go from an upstream flow of 100 m 3 per hour to 10 m 3 per hour, the downstream flow will make it possible to obtain a total flow, which will always be greater than 100 m 3 per hour, thanks reduction of the fluid outlet section 12 of the compression device 10 according to the invention, which makes it possible to increase the induction rate, under the influence of three factors, which are the rise in pressure and speed on the outlet head, as the flow rate decreases, until the fluid pressure in the outlet is almost doubled, reducing the volume of the compressed air jet 12 inside the sheath 160, frees up an increasingly large space for the induced air and the maintenance of the contact perimeter of the induced air jet due to the flattening of the envelope 20 of deformable revolution mentioned above.

Si on souhaite maintenir le débit aval de l'appareil pour une réduction de débit amont d'environ 50%, la perte de charge amont du bloc 120 est initialement réglée à une valeur maximale pour que lors de la réduction du débit amont de 50 % la réduction de perte de charge correspondante à la réduction de débit d'environ 50 % se retrouve en aval, de sorte que la pression du flux sortant est augmentée d'une valeur de pression correspondant sensiblement au trois quart de la différence de perte de charge obtenue. Par exemple, pour une perte de charge du bloc amont de 200 Pa initiale et une valeur de pression de sortie du flux d'environ 200 Pa, si on réduit de 50 % le débit, la perte de charge amont devient 50 Pa, et l'écart de perte de charge de 150 Pa se retrouve sensiblement en aval au niveau de la membrane, de sorte que la pression de sortie est maintenant d'environ 350 Pa. Par contre, la pression entrante du flux est restée inchangée à 400 Pa. On observe ainsi que conformément à l'appareil selon l'invention à partir d'un flux incident à pression sensiblement constante, on obtient une pression variable du flux d'air sortant.If you want to maintain the downstream flow of the device for a reduction upstream flow of approximately 50%, the upstream pressure drop of block 120 is initially set to a maximum value so that when reducing the flow upstream by 50% the reduction in pressure drop corresponding to the reduction in flow of about 50% is found downstream, so that the pressure of the outgoing flow is increased by a pressure value corresponding substantially to three quarters of the difference in pressure drop obtained. For example, for a pressure drop of the initial 200 Pa upstream block and a flow outlet pressure value about 200 Pa, if the flow is reduced by 50%, the upstream pressure drop becomes 50 Pa, and the pressure drop difference of 150 Pa is found substantially downstream at diaphragm level, so the outlet pressure is now about 350 Pa. On the other hand, the incoming flow pressure remained unchanged at 400 Pa. thus observes that in accordance with the apparatus according to the invention from a flow incident at substantially constant pressure, variable pressure is obtained outgoing air flow.

De ce fait, on peut construire un appareil qui, pour une réduction de débit de 50 %, maintient un débit aval initial inchangé.Therefore, one can build a device which, for a reduction of flow rate of 50%, maintains an initial downstream flow rate unchanged.

L'invention permet ainsi d'obtenir une température de soufflage de grand confort puisque celle-ci peut être très proche de la température ambiante.The invention thus makes it possible to obtain a blowing temperature of great comfort since it can be very close to room temperature.

On donne ci-après un exemple de réalisation. An exemplary embodiment is given below.

Pression de l'air en amont :

  • température de soufflage amont : 8 °C
  • température du local : 25°C
  • température du mélange : 21,7°C
  • taux d'induction : au moins 5,14
  • écart de température avec l'ambiante : 3,3°C
  • débit d'air amont : 36 m3 par heure
  • débit d'air aval de l'ouverture maximale, environ 185 m3 par heure.
Upstream air pressure:
  • upstream supply temperature: 8 ° C
  • room temperature: 25 ° C
  • temperature of the mixture: 21.7 ° C
  • induction rate: at least 5.14
  • temperature difference with the ambient: 3.3 ° C
  • upstream air flow: 36 m 3 per hour
  • air flow downstream of the maximum opening, approximately 185 m 3 per hour.

Avec une réduction de puissance d'au moins 80 % le débit aval sera égal à 140 m3 par heure et le taux d'induction passera à 7,7, pour une ouverture minimale de l'enveloppe 20 de la révolution, alors que précédemment l'ouverture était maximale.With a power reduction of at least 80% the downstream flow will be equal to 140 m 3 per hour and the induction rate will increase to 7.7, for a minimum opening of the envelope 20 of the revolution, whereas previously the opening was maximum.

La température du mélange obtenu est la suivante, mathématiquement : (18 m 3 / h x 8°C) + (6,7 x 18m 3 / h x 25°C)7,7 x 18 m 3 / h = 22,8°C    l'écart de température avec l'ambiante est de 2,2°C, d'où un très grand confort.The temperature of the mixture obtained is as follows, mathematically: (18 m 3 / hx 8 ° VS ) + (6.7 x 18 m 3 / hx 25 ° VS ) 7.7 x 18 m 3 / h = 22.8 ° C the temperature difference with the ambient is 2.2 ° C, hence very comfortable.

Ainsi, le dispositif de transfert selon l'invention maintient une portée d'air sensiblement constante et permet en fait que le débit d'air s'autorégule ou se compense automatiquement en entraínant la suppression du besoin de canalisations, pompes, batterie froide ou chaude, toute la puissance nécessaire pouvant être désormais directement transmise à l'air ou tout fluide équivalent, pour l'obtention d'un confort sans équivalent.Thus, the transfer device according to the invention maintains a range air substantially constant and in fact allows the air flow to self-regulate or automatically compensates by causing the removal of the need to pipes, pumps, cold or hot coil, all the power needed can now be directly transmitted to air or any equivalent fluid, for unparalleled comfort.

On comprend ainsi que l'invention permet d'obtenir des avantages techniques déterminants précédemment énoncés. L'invention comprend tous les moyens constituant des équivalents techniques ainsi que leurs diverses combinaisons.It is thus understood that the invention makes it possible to obtain advantages determining techniques previously stated. The invention includes all means constituting technical equivalents and their various combinations.
