Description

La présente invention concerne un espace de détente et notamment un salon à vocation de fumoir. The present invention relates to a relaxation area and in particular a smoking lounge.
On connaît des fumoirs, notamment dans les pays où la législation a imposé des règles en ce qui concerne l'utilisation du tabac dans les lieux publics, où les fumeurs se trouvent regroupés à l'écart des lieux conviviaux où se retrouvent les non fumeurs. La plupart du temps ces fumoirs sont dépourvus d' attractivité, notamment pour deux raisons essentielles, à savoir d'une part leur décoration et d'autre part leur atmosphère qui, faute de moyens d'aération efficaces, est souvent difficilement respirable en raison de l'odeur désagréable qu'ils dégagent, odeur que les utilisateurs retrouvent ensuite sur leurs vêtements. On sait en effet que les moyens d' aération mis en oeuvre dans les locaux où l'on souhaite assurer un renouvellement d'air confortable, que ces moyens d'aération assurent ou non une fonction supplémentaire de conditionnement d'air, sont généralement dépourvus d'efficacité dès lors que l'on souhaite les utiliser pour l'aération de locaux enfumés.Smokers are known, particularly in countries where legislation has imposed rules on the use of tobacco in public places, where smokers are grouped away from friendly places where non-smokers meet. Most of the time these smoking rooms are devoid of attractiveness, especially for two main reasons, namely on the one hand their decoration and on the other hand their atmosphere which, lacking effective means of aeration, is often difficult to breathe due to the unpleasant odor they emit, smell that users then find on their clothes. It is known that the ventilation means used in the premises where it is desired to provide a comfortable air exchange, whether or not these aeration means provide an additional air conditioning function, are generally lacking. efficiency when it is desired to use them for ventilation of smoky premises.
La plupart du temps ces moyens d' aération sont constitués de bouches d'aération de petites dimensions qui sont aptes à amener dans le local un flux d' air pur et à extraire de celui-ci un flux d'air vicié. On est ainsi conduit, lorsque l'on souhaite renouveler rapidement un volume d'air important d'un local à partir de bouches de soufflage/aspiration de petites dimensions, à faire appel à un flux d'air doté d'une vitesse de circulation relativement importante. Dans ces conditions un problème survient en raison du fait, qu'au delà d'une certaine vitesse, cet air provoque, au niveau de la peau des usagers du local, une sensation de froid, même dans le cas où l'air puisé se trouve à une température habituellement considérée comme étant une température de confort lorsque l'air est statique. C'est le phénomène dit du courant d'air.Most of the time these means of aeration consist of small air vents which are able to bring into the room a flow of clean air and to extract from it a stale airflow. It is thus conducted, when it is desired to quickly renew a large volume of air from a room from small blow / suction mouths, to use a flow of air with a speed of circulation relatively important. Under these conditions a problem arises due to the fact that, beyond a certain speed, this air causes, at the level of the skin of the users of the premises, a sensation of cold, even in the case where the pulsed air becomes found at a temperature usually considered as a comfort temperature when the air is static. This is the so-called airflow phenomenon.
Une solution pour disposer d'un volume d'air de renouvellement confortable tout en conservant à celui-ci une vitesse raisonnable, c'est-à-dire ne créant pas vis-à- vis des usagers une sensation de froid, est d'augmenter le diamètre des bouches et des conduits d'aération.A solution for having a comfortable air volume renewal while maintaining it at a reasonable speed, that is to say not creating vis-à-vis users a feeling of cold, is to increase the diameter of the vents and air ducts.
On se heurte alors à une difficulté, dans la mesure où les conduits sont habituellement disposés dans les faux plafonds des habitations, et cette augmentation de volume des conduits se traduit alors par une perte de volume difficilement admissible.One then comes up against a difficulty, insofar as the ducts are usually arranged in the false ceilings of the houses, and this increase in volume of the ducts then results in a loss of volume difficult to qualify.
On a proposé dans les brevets japonais JP 06 229584 et JP 04 161749 de réaliser des dispositifs de climatisation dans lesquels l'alimentation en air se fait à partir du sol au travers d'une plaque perforée qui est percée d'une multitude de trous et qui s'étend sur la surface de la pièce à climatiser. Cet air est puisé avec un « effet piston » et évacué par le plafond qui, à cet effet, est également percé sur toute sa surface d'une multitude de trous .It has been proposed in Japanese patents JP 06 229584 and JP 04 161749 to provide air conditioning devices in which the air is supplied from the ground through a perforated plate which is pierced with a multitude of holes and which extends on the surface of the room to be air conditioned. This air is drawn with a "piston effect" and evacuated through the ceiling which, for this purpose, is also pierced over its entire surface with a multitude of holes.
On a cependant constaté que l'air qui traverse une plaque perforée, autrement dit une paroi de faible épaisseur, avait tendance, lorsque les trous étaient de faible diamètre, c'est-à-dire de l'ordre de 2 à 5 mm, à générer des bruits d'écoulement importants, voire même des sifflements .It has been found, however, that the air passing through a perforated plate, in other words a thin wall, had a tendency, when the holes were of small diameter, that is to say of the order of 2 to 5 mm, to generate significant flow noises, or even whistles.
Or, lorsque l'on souhaite réaliser un espace de détente il est souhaitable à la fois d'une part que les trous du plancher soient de faible diamètre afin d' éviter les problèmes éventuels liés aux talons féminins de petites dimensions et, d'autre part, qu'il soit possible de bénéficier dans ledit espace d'un silence qui ne soit pas troublé par des bruits de ventilation. La présente invention a pour but de remédier à ces inconvénients en proposant un espace de détente dans lequel les moyens de renouvellement de l'air sont en mesure d' assainir sans difficulté la totalité du volume de celui- ci, sans pour autant créer au niveau des usagers une sensation de froid ou de courant d' air quelconque et ceci en réalisant un renouvellement d'air par courant laminaire. La présente invention a également pour but de proposer la réalisation d'un tel espace de détente dans lequel l'alimentation en air se fait à partir de la surface totale du plancher et l'aspiration à partir de la surface totale du plafond, et ceci sans que l'alimentation en air ne génère ni courant d'air ni bruit d'écoulement d'air perceptible. La présente invention a ainsi pour objet un espace de détente, notamment un salon fumoir, du type comportant des moyens de renouvellement de l'air pourvus de moyens d'alimentation et de moyens d'aspiration, lesdits moyens de renouvellement étant constitués de trous se répartissant sur la totalité du plancher et du plafond de celui-ci, caractérisé en ce que les trous d' au moins le plancher sont constitués d'au moins deux parties, à savoir une partie aval débouchant dans ledit espace de détente et une partie amont de plus grande section que la partie aval débouchant sur l'autre face du plancher.However, when one wishes to achieve a space of relaxation it is desirable both on the one hand that the floor holes are of small diameter to avoid the possible problems related to small female heels and other On the other hand, it is possible to benefit in this space from a silence which is not disturbed by ventilation noises. The present invention aims to overcome these disadvantages by providing a relaxation space in which the air renewal means are able to clean up without difficulty the entire volume of it, without creating at the level users a feeling of cold or any air flow and this by performing a renewal of air by laminar current. The present invention also aims to propose the realization of such a relaxation space in which the air supply is from the total surface of the floor and suction from the total surface of the ceiling, and this without the air supply generating neither air current nor noticeable air flow noise. The present invention thus relates to a relaxation space, in particular a smoking lounge, of the type comprising air renewal means provided with supply means and suction means, said renewal means being constituted by holes of spreading over the entire floor and the ceiling thereof, characterized in that the holes of at least the floor consist of at least two parts, namely a downstream portion opening into said expansion space and an upstream portion larger section than the downstream part opening on the other side of the floor.
La section de sortie de la partie aval des trous sera préférentiellement de l'ordre du quart de la section de la partie amont.The outlet section of the downstream portion of the holes will preferably be of the order of a quarter of the section of the upstream portion.
Les trous auront habituellement une section droite circulaire et le diamètre des trous aval pourra être compris entre 2 et 5 mm et sera préférentiellement de l'ordre de 3 mm. Par ailleurs le diamètre des trous amont pourra être compris entre 8 et 20 mm et sera préférentiellement de l'ordre de 15 mm. Dans une variante de mise en oeuvre, les trous pourront être constitués d'un trou aval, d'un trou amont, et d'un trou intermédiaire. Le diamètre des trous amont pourra être de l'ordre de 12 mm et le diamètre des trous intermédiaires pourra être de l'ordre de 8 mm. La longueur des trous aval pourra être comprise entre 5 et 8 mm et être préférentiellement égale à 6 mm. La longueur des trous amont pourra être comprise entre 20 et 60 mm et être préférentiellement égale à 40 mm. Enfin la longueur des trous intermédiaires pourra être comprise entre 5 et 15 mm et être préférentiellement égale à 10 mm.The holes will usually have a circular cross section and the diameter of the downstream holes may be between 2 and 5 mm and will preferably be of the order of 3 mm. Moreover, the diameter of the upstream holes may be between 8 and 20 mm and will preferably be of the order of 15 mm. In an alternative embodiment, the holes may consist of a downstream hole, an upstream hole, and an intermediate hole. The diameter of the upstream holes may be of the order of 12 mm and the diameter of the intermediate holes may be of the order of 8 mm. The length of the downstream holes may be between 5 and 8 mm and preferably be equal to 6 mm. The length of the upstream holes may be between 20 and 60 mm and preferably be equal to 40 mm. Finally, the length of the intermediate holes may be between 5 and 15 mm and preferably be equal to 10 mm.
Suivant l'invention les moyens d'alimentation en air seront actifs à partir du plancher du local et les moyens d'aspiration seront actifs à partir du plafond de celui-ci. Dans un mode de mise en oeuvre préféré de la présente invention l'espace de détente comportera un faux plancher et un faux plafond dans lesquels les trous seront percés, ces derniers étant répartis de façon régulière, notamment avec une densité de répartition de l'ordre de 3000/m2, sur la totalité de ceux-ci et seront distribués notamment en forme de quinconce.According to the invention the air supply means will be active from the floor of the room and the suction means will be active from the ceiling thereof. In a preferred embodiment of the present invention the relaxation space will include a false floor and a false ceiling in which the holes will be drilled, the latter being evenly distributed, especially with a distribution density of the order 3000 / m 2 , on all of them and will be distributed in the form of a quincunx.
Préférentiellement l'air sera soufflé par le plancher et aspiré par le plafond et un volume tampon supérieur sera prévu entre le plafond et un faux plafond dans lequel déboucheront les moyens d'aspiration. De même un volume tampon inférieur sera prévu entre le plancher et le sol dans lequel déboucheront les moyens d'alimentation d'air.Preferentially, the air will be blown through the floor and sucked by the ceiling and a higher buffer volume will be provided between the ceiling and a false ceiling in which the suction means will emerge. Likewise, a lower buffer volume will be provided between the floor and the floor in which the air supply means will open.
Les moyens d'alimentation et d'aspiration en air du plancher pourront être constitués d'un monobloc de ventilation à double flux, éventuellement pourvu d'un dispositif récupérateur de chaleur, et de moyens de conditionnement d'air. On fera en sorte que l'écoulement de l'air soit du type laminaire. Préférentiellement, les moyens d'alimentation en air seront pourvus de moyens de contrôle de la température et de l'hygrométrie, ces moyens étant éventuellement pourvus de moyens de contrôle aptes à les contrôler, les modifier et assurer leur maintenance à distance.The means for supplying and extracting air from the floor may consist of a monobloc double flow ventilation, possibly provided with a heat recovery device, and air conditioning means. The flow of air will be made of a laminar type. Preferably, the air supply means will be provided with temperature and hygrometry control means, these means possibly being provided with control means able to control them, modify them and ensure their maintenance at a distance.
Dans une variante intéressante de l'invention l'espace de détente constituera un ensemble modulaire apte à se combiner avec d'autres modules de même type. Ces modules comprendront une structure comprenant un sol et un plancher, un plafond et un faux-plafond, des parois latérales, éventuellement en verre, pourvues d'au moins une ouverture, et une paroi délimitant un caisson recevant l'ensemble des moyens techniques de traitement- de l'air. Ces derniers pourront bien entendu être indépendants. L'alimentation en air et l'aspiration se feront par l'intermédiaire de collecteurs respectivement reliés aux moyens de soufflage et aux moyens d'aspiration. Le débit des moyens d'aspiration sera préférentiellement supérieur au débit des moyens de soufflage, de façon à créer dans l'espace de détente une légère dépression par rapport à l'atmosphère extérieure.In an advantageous variant of the invention the relaxation space will constitute a modular assembly suitable for combining with other modules of the same type. These modules will comprise a structure comprising a floor and a floor, a ceiling and a false ceiling, side walls, possibly made of glass, provided with at least one opening, and a wall delimiting a box receiving all the technical means of air treatment. These may of course be independent. The air supply and suction will be through collectors respectively connected to the blowing means and the suction means. The flow of the suction means will preferably be greater than the flow rate of the blowing means, so as to create in the expansion space a slight depression with respect to the external atmosphere.
Par ailleurs la base de la porte d'accès sera pourvue de moyens aptes à créer devant celle-ci un rideau formé d'un flux d'air à plus grande vitesse que la vitesse de l'air de traitement dans ledit espace. Les moyens de création de ce rideau d'air seront constitués d'une fente qui s'étendra au moins sur la largeur de la porte et qui sera alimentée par des moyens aptes à souffler ledit flux d'air à l'ouverture de celle-ci. La présente invention a également pour objet un caisson modulaire destiné, par la jonction de plusieurs de ceux-ci, à constituer un faux plancher et/ou un faux plafond d'un espace de détente, dans lequel on admet dans ce dernier un flux d'air sous pression par des trous régulièrement répartis sur la totalité de la surface du plancher et on évacue ce flux d'air par des trous régulièrement répartis sur la totalité de la surface du plafond, caractérisé en ce que le caisson comprend une face principale horizontale percée des susdits trous et des faces latérales percées d'au moins un orifice de communication de l'ensemble des caissons, l'air étant soufflé sous pression dans l'espace de détente à partir des caissons formant le plancher et aspiré dans cet espace par les caissons formant plafond. Préférentiellement le caisson modulaire comportera des moyens aptes à le connecter aux caissons qui lui sont adjacents .Furthermore, the base of the access door will be provided with means capable of creating in front of the latter a curtain formed by a flow of air at a higher speed than the speed of the treatment air in said space. The means for creating this air curtain will consist of a slot which will extend at least over the width of the door and which will be fed by means able to blow said air flow at the opening of the door. this. The present invention also relates to a modular housing intended, by the junction of several thereof, to constitute a false floor and / or a false ceiling of a relaxation space, in which one admits in the latter a flow of air under pressure through holes regularly distributed over the entire surface of the floor and this air flow is evacuated by holes regularly distributed over the entire surface of the ceiling, characterized in that the box comprises a horizontal main face pierced with the aforesaid holes and side faces pierced by at least one communication orifice of all the caissons, the air being blown under pressure into the expansion space from the caissons forming the floor and sucked into this space by the caissons forming a ceiling. Preferably, the modular box will comprise means able to connect it to the caissons that are adjacent to it.
Par ailleurs les trous pourront être constitués d' au moins deux parties, à savoir une partie aval débouchant dans ledit espace de détente et une partie amont de plus grande section que la partie aval débouchant sur l'intérieur du caisson.Furthermore, the holes may consist of at least two parts, namely a downstream portion opening into said expansion space and an upstream portion of larger section that the downstream portion opening on the inside of the box.
Enfin le caisson modulaire pourra être destiné à constituer un plancher et/ou un plafond d'un espace de détente comportant toutes les spécificités précédemment décrite.Finally the modular box may be intended to constitute a floor and / or a ceiling of a relaxation area having all the previously described specificities.

On a représenté sur la figure 1 un espace de détente constitué en l'espèce d'un salon fumoir 1 suivant l'invention qui est constitué à partir d'une enveloppe architecturale formée de parois murales 3, d'un plafond 5 et d'un sol 7. Pour constituer le salon fumoir on a disposé sous le plafond 5 un faux plafond 9 à une certaine distance de celui-ci, de façon à constituer entre eux un volume tampon supérieur 11 qui constituera, ainsi qu'exposé ci- après, un collecteur d'air.FIG. 1 shows a relaxation space constituted in this instance by a smoking lounge 1 according to the invention which is constituted from an architectural envelope formed by wall walls 3, a ceiling 5 and 7. In order to constitute the smoking room, a false ceiling 9 has been placed under the ceiling 5 at a certain distance from it, so as to constitute between them an upper buffer volume 11 which will constitute, as explained hereinafter , an air collector.
De même, au-dessus du sol 7, on a disposé une dalle support 13, ou plancher, à une distance de celui-ci, de façon à prévoir entre eux un volume tampon 15 inférieur formant également un collecteur.Likewise, above the ground 7, a support slab 13, or floor, has been disposed at a distance from it, so as to provide a lower buffer volume between them, also forming a collector.
Le faux plafond 9 et le plancher 13 sont percés sur toute leur surface de trous 16 qui sont répartis uniformément, notamment en quinconce. La densité de répartition de ces trous est de l'ordre de 3000 par m2. On pourrait bien entendu adopter une autre disposition des trous ou une autre densité de ces derniers en fonction des paramètres d'écoulement du flux d'air, ainsi que mentionné ci-après . On rappellera que les planchers soufflants de type connu sont constitués de plaques métalliques percées sur toute leur surface d'une grande quantité de trous. En raison de la faible longueur de chacun de ces trous le flux df air qui les traverse ne subit pas de perte de charge importante mais on a constaté par contre que l'écoulement de l'air au travers de ces derniers avait pour effet de générer des bruits d'écoulement importants.The false ceiling 9 and the floor 13 are drilled over their entire surface with holes 16 which are uniformly distributed, in particular staggered. The distribution density of these holes is of the order of 3000 per m 2 . It would of course be possible to adopt another arrangement of the holes or another density of the latter as a function of the flow parameters of the air flow, as mentioned below. It will be recalled that the known type of blower floors consist of metal plates pierced over their entire surface with a large number of holes. Due to the short length of each of these holes the air stream f flowing through them is not subjected to high pressure loss but it has been found by that against the flow of air through the latter had the effect of generate significant flow noises.
Suivant la présente invention on souhaite réaliser le plancher 13 dans un matériau massif tel que le bois, préférentiellement dans des essences nobles, le marbre, le verre etc. On comprend qu'un plancher réalisé en de tels matériaux, pour être suffisamment résistant afin d' assurer la fonction de maintien qui lui est propre, doit être pourvu d'une épaisseur importante par rapport à celle d'une plaque de l'état antérieur de la technique. C'est pourquoi, dans ces conditions, les trous, notamment lorsqu'ils sont de faible diamètre, engendrent des pertes de charge importantes. Or en raison de la vocation même des espaces de détente suivant l'invention les trous doivent être de faible diamètre afin de se situer en dessous de celui d'un talon de chaussure notamment de type dit talon-aiguille.According to the present invention it is desired to produce the floor 13 in a solid material such as wood, preferably in noble woods, marble, glass, etc. It is understood that a floor made of such materials, to be sufficiently resistant to ensure the maintenance function of its own, must be provided with a significant thickness compared to that of a plate of the previous state of the technique. This is why, in these conditions, the holes, especially when they are of small diameter, generate significant pressure drops. However, because of the very vocation of the relaxation spaces according to the invention the holes must be of small diameter to be below that of a shoe heel, in particular of the so-called stiletto-heel type.
Les trous mis en oeuvre dans le cadre de la présente invention devront donc être de faible diamètre, n'engendrer que de faibles pertes de charge et néanmoins fournir un débit d'air important sans créer de bruit au niveau de l'écoulement de l'air.The holes used in the context of the present invention must therefore be of small diameter, generate only low pressure losses and nevertheless provide a high air flow without creating noise in the flow of the air.
On a constaté qu'en réalisant en amont de la partie du trou qui débouche dans le local à traiter- un autre trou de plus grand diamètre, on résolvait du même coup les problèmes relatifs à la perte de charge et les problèmes relatifs aux bruits générés par l'écoulement de l'air à travers un élément de faible épaisseur soit de l'ordre de 5 à 6 mm. Dans un premier mode de mise en oeuvre de l'invention qui est représenté sur la figure 2, le plancher 13 est réalisé dans du bois massif, tel que notamment du chêne, d'épaisseur e_ de l'ordre de 30 mm. Par ailleurs la partie aval 16a du trou 16 qui débouche dans le salon fumoir 1 a un diamètre dl de l'ordre de 2 à 5 mm et préférentiellement voisin de 3 mm et a une longueur el de l'ordre de 4 à 7 mm et préférentiellement voisin de 6 mm. En amont de cette partie 16a on a réalisé une autre partie de trou 16b d'un diamètre d2 égal à au moins le double du diamètre dl de la partie de trou 16a. La longueur de la partie 16b s'étend sur le reste e2 de l'épaisseur du plancher 13.It was found that by performing upstream of the portion of the hole that opens into the room to be treated- another hole of larger diameter, it was solved at the same time the problems relating to the pressure drop and the problems relating to the noise generated. by the flow of air through a thin member is of the order of 5 to 6 mm. In a first embodiment of the invention which is shown in Figure 2, the floor 13 is made of solid wood, such as oak, with a thickness e_ of the order of 30 mm. Furthermore, the downstream portion 16a of the hole 16 which opens into the smoking lounge 1 has a diameter d1 of the order of 2 to 5 mm and preferably close to 3 mm and has a length el of the order of 4 to 7 mm and preferably close to 6 mm. Upstream of this portion 16a was made another hole portion 16b of diameter d2 equal to at least twice the diameter d1 of the hole portion 16a. The length of the portion 16b extends over the remainder e2 of the thickness of the floor 13.
Ainsi que représenté sur la figure 3 le plancher 13 peut être réalisé en deux parties qui sont superposées, à savoir d'une part une base 13a dont l'épaisseur e2 peut être égale à celle de la partie de trou 16b et qui pourra par exemple être réalisée en un matériau possédant de bonnes qualités absorbantes tant au niveau thermique qu'acoustique et, d'autre part une couche de surface 13b dont l'épaisseur sera égale à la partie de trou supérieure 16a et qui sera faite d'un matériau apte à résister aux frottements et aux chocs et qui sera réalisée dans un matériau plus « noble » de façon à conférer au plancher 13 un aspect de qualité.As shown in FIG. 3, the floor 13 can be made in two parts which are superimposed, namely on the one hand a base 13a whose thickness e2 can be equal to that of the hole portion 16b and which could, for example be made of a material having good absorbing qualities both thermally and acoustically and on the other hand a surface layer 13b whose thickness will be equal to the upper hole portion 16a and which will be made of a suitable material to resist friction and shocks and which will be made of a more "noble" material so as to give the floor 13 a quality appearance.
Par ailleurs le fait de donner à la partie amont 16b des trous 16 un plus grand diamètre permettra de faciliter le bon positionnement relatif des deux partie de plancher 13a et 13b.Moreover, giving the upstream portion 16b holes 16 a larger diameter will facilitate the proper relative positioning of the two floor portions 13a and 13b.
De façon à améliorer l'écoulement de l'air dans les trous 16 en évitant les tourbillons générateurs de bruits parasites on pourra, ainsi que représenté sur la figure 4, étager la partie de trou de diamètre d2 en réalisant une troisième partie de trou 16c de diamètre intermédiaire d3 disposée juste en amont de la partie de trou aval 16a. Ainsi que précédemment, et comme représenté sur la figure 5, chaque partie de trou 16a, 16b, 16c pourra être réalisée dans une couche de matériau différente, ayant chacune des caractéristiques spécifiques. Ainsi la couche inférieure constituera le support mécanique et pourra être réalisée par exemple dans du bois de type aggloméré, la couche intermédiaire pourra être réalisée dans un matériau possédant de bonnes qualités absorbantes tant au niveau thermique qu'acoustique et la couche de surface pourra être faite d'un matériau apte à résister aux frottements et aux chocs et qui sera réalisée dans un matériau plus « noble » apte à conférer au plancher 13 un aspect de qualité.In order to improve the flow of air into the holes 16 while avoiding the whirlwinds generating parasitic noise, it will be possible, as shown in FIG. 4, to stagger the hole portion of diameter d2 by making a third hole portion 16c. of intermediate diameter d3 disposed just upstream of the downstream hole portion 16a. As previously, and as shown in FIG. 5, each hole portion 16a, 16b, 16c may be made in a layer of different material, each having specific characteristics. Thus, the lower layer will constitute the mechanical support and may be made for example in agglomerated type wood, the intermediate layer may be made of a material having good absorbing qualities both thermally and acoustically and the surface layer may be made a material capable of withstanding friction and shocks and which will be made of a more "noble" material capable of giving the floor 13 a quality appearance.
On pourra également, ainsi que représenté sur la figureWe can also, as shown in the figure
6, donner à la partie de trou 16b disposée en amont du trou de sortie aval 16a, la forme d'un convergent ayant pour effet de diminuer encore les perturbations de l'écoulement qui sont génératrices de bruit.6, give the hole portion 16b disposed upstream of the downstream exit hole 16a, the shape of a convergent having the effect of further reducing the disturbances of the flow that are generating noise.
Les trous 16, notamment pour des rasons liées à leur fabrication, seront habituellement de section droite circulaire, mais ils pourront également pour certaines applications spécifiques avoir d'autres formes, notamment carrées .The holes 16, in particular for rasons related to their manufacture, will usually be of circular cross section, but they may also for certain specific applications have other shapes, including square.
Ainsi que représenté sur la figure 7, le volume tampon inférieur 15 est pourvu d'une conduite d'alimentation en air sous pression 18 et le volume tampon supérieur 11 est pourvu d'une conduite d'aspiration 20.As shown in FIG. 7, the lower buffer volume 15 is provided with a pressurized air supply line 18 and the upper buffer volume 11 is provided with a suction line 20.
On comprend, dans ces conditions que le volume du salon est parcouru par un flux d' air se dirigeant du bas vers le haut, ce qui s'est révélé particulièrement efficace pour l'évacuation des fumées générées dans celui-ci. Préférentiellement on ajustera les débits d'air de façon que le flux à l'intérieur du salon fumoir soit de type laminaire . Dans un mode de mise en oeuvre de l'invention on fera en sorte de régler le débit Ql d'aspiration de l'air à une valeur supérieure au débit d' alimentation Q2 de façon à entretenir dans le salon une légère dépression. Une telle disposition permet d'éviter, notamment lorsque le salon est utilisé en tant que fumoir, la propagation à l'extérieur des fumées générées à l'intérieur de celui-ci.It is understood, in these conditions that the volume of the living room is traversed by a flow of air from the bottom to the top, which has been particularly effective for the evacuation of fumes generated therein. Preferentially, the air flow rates will be adjusted so that the flow inside the smoking lounge is of laminar type. In one embodiment of the invention, the air intake flow Q1 will be set to a value greater than the supply flow rate Q2 so as to maintain a slight depression in the salon. Such an arrangement avoids, especially when the living room is used as a smoking room, the propagation to the outside of the fumes generated inside thereof.
Le débit d'aspiration Ql sera tel qu'il permette de renouveler l'air du salon entre vingt et cinquante fois par heure et préférentiellement environ trente fois par heure. Ainsi, par exemple dans le cas d'un salon de 45 m3, le débit d'aspiration Ql sera compris entre 900 et 2200 m3/h et sera préférentiellement de l'ordre de 1500 m3/h. On fera en sorte d'alimenter le caisson inférieur avec un débit Q2 de l'ordre de 30% inférieur à l'aspiration de façon à mettre le volume du salon en légère dépression. Ainsi, si par exemple le débit d'aspiration est de 1500 m3/h, le débit de soufflage dans le caisson sera préférentiellement de l'ordre de 1100 m3/h. On a constaté dans ces conditions que l'atmosphère dans le salon était des plus agréables à ses occupants et que ceux-ci ne subissaient aucune gêne aussi bien sur les plans olfactifs, phoniques, et thermiques, que sur celui des courants d'air éventuels. On a représenté sur la figure 7 un exemple de moyens d'alimentation/extraction et conditionnement de l'air dans le salon 1. La conduite d'alimentation d'air 18 est réunie, par l'intermédiaire d'un amortisseur de son 22, à la sortie 23 d'un bloc de ventilation double flux 25, et la conduite d'extraction d'air 20 est réunie, par l'intermédiaire d'un amortisseur de son 26, à l'entrée 27 du bloc de ventilation 25. Ce dernier aspire de l'air neuf par sa conduite d'entrée 29. Eventuellement une pompe à chaleur 31 est disposée sur une dérivation 33 en sortie du bloc de ventilation 25 et permet, en fonction des besoins, de réchauffer ou refroidir l'air qui est puisé dans le salon 1. Dans une variante de mise en oeuvre de l'invention, qui est représentée de façon schématique sur les figures 8a et 8b, l'espace de détente est de type modulaire et transportable, c'est-à-dire que tous ses éléments forment un ensemble autonome déplaçable. Cet ensemble est ainsi constitué d'une structure formée d'un sol 7 et d'un plancher perforé 13 délimitant le caisson d'alimentation en air 15, d'un plafond 5 et d'un faux plafond perforé 9 délimitant le caisson supérieur d'aspiration 11, et de parois de verre 3' . Le fond du salon 1 est fermé par une cloison 35 délimitant un volume arrière constituant un local technique 37 recevant les moyens d'alimentation / extraction et conditionnement de l'air. La face avant peut être avantageusement constituée de parois de verre 3' pourvues d'une porte d'accès 34. Un tel salon peut être disposé de façon définitive ou temporaire en tout lieu où des moyens d'alimentation électrique son disponibles.The suction flow Ql will be such that it allows to renew the air of the salon between twenty and fifty times per hour and preferably about thirty times per hour. Thus, for example in the case of a living room of 45 m 3 , the suction flow Ql will be between 900 and 2200 m 3 / h and will preferably be of the order of 1500 m 3 / h. It will be necessary to supply the lower box with a flow rate Q2 of the order of 30% lower than the suction so as to bring the volume of the living room in slight depression. Thus, if for example the suction flow rate is 1500 m 3 / h, the blast flow rate in the box will preferably be of the order of 1100 m 3 / h. It was found in these conditions that the atmosphere in the living room was most pleasing to its occupants and that they did not suffer any discomfort as well on the olfactory, phonic, and thermal, than on that of the possible currents of air . FIG. 7 shows an example of supply / extraction and air conditioning means in the living room 1. The air supply duct 18 is connected via a sound absorber 22 at the outlet 23 of a double flow ventilation unit 25, and the air extraction line 20 is connected, via a sound absorber 26, to the inlet 27 of the ventilation block 25 The latter sucks in fresh air through its inlet duct 29. Optionally, a heat pump 31 is arranged on a bypass 33 at the outlet of the ventilation block 25 and, as needed, allows the air which is drawn from the living room 1 to be heated or cooled. In an alternative embodiment of the invention, which is shown schematically in Figures 8a and 8b, the relaxation space is of the modular and transportable type, that is to say that all its elements form a movable self-contained assembly. This assembly thus consists of a structure formed of a floor 7 and a perforated floor 13 delimiting the air supply box 15, a ceiling 5 and a perforated false ceiling 9 delimiting the upper box. suction 11, and glass walls 3 '. The bottom of the living room 1 is closed by a partition 35 defining a rear volume constituting a technical room 37 receiving the means of supply / extraction and conditioning of the air. The front face may advantageously consist of glass walls 3 'provided with an access door 34. Such a living room may be permanently or temporarily disposed in any place where power supply means are available.
Les différents modules peuvent être combinés entre eux, de façon à former un volume global ajustable en surface, en fonction des souhaits des utilisateurs. Les moyens d'alimentation et de régulation d'air 25 des espaces de détente suivant l'invention peuvent être pourvus de modules de commande à distance permettant de surveiller de façon centralisée des espaces de détente appartenant à plusieurs utilisateurs et d' intervenir pour les régler, les modifier ou les réparer à distance et ceci de façon spécifique en fonction des souhaits de chacun.The different modules can be combined with each other, so as to form an overall volume adjustable on the surface, according to the wishes of the users. The means for supplying and regulating the air of the relaxation spaces according to the invention may be provided with remote control modules making it possible to centrally monitor relaxation areas belonging to several users and to intervene to regulate them. , modify or repair them remotely and this specifically depending on the wishes of each.
Dans une autre variante de mise en oeuvre de la présente invention les orifices donnant accès sur l'extérieur, tels que notamment la porte 34 ou les passe-plats éventuels, pourront être pourvus d' un rideau d' air destiné à éviter toute fuite de fumées de l'intérieur vers l'atmosphère extérieure et ceci, ainsi que précisé précédemment, afin d'éviter, lorsque l'espace de détente fait fonction de salon fumoir, toute pollution du volume environnant par la fumée éventuelle du salon.In another alternative embodiment of the present invention the orifices giving access to the outside, such as in particular the door 34 or the possible pass-dishes, may be provided with a curtain of air intended to prevent any leakage of fumes from the inside to the outside atmosphere and this, as previously specified, to avoid, when the space of relaxation acts as lounge smoker , any pollution of the surrounding volume by the possible smoke of the living room.
Ce rideau d'air est obtenu, par exemple en ce qui concerne les portes 34 d'accès au salon, et ainsi que représenté sur la figure 9, en réalisant dans le plancher 13 du local et sur toute la largeur des portes 34 une fente 39 par laquelle, à l'ouverture des portes 34, on puise du bas vers le haut un flux d'air à plus grande vitesse que celui de l'air du local.This air curtain is obtained, for example as regards the doors 34 for access to the living room, and as shown in FIG. 9, by producing in the floor 13 of the room and over the entire width of the doors 34 a slot 39 by which, at the opening of the doors 34, it draws from bottom to top a flow of air at a higher speed than that of the room air.
A cet effet, ainsi que représenté sur la figure 9, on peut par exemple réaliser un caisson 41 entourant la fente 39 qui est alimenté par des moyens de mise en pression 43 qui sont activés par détection d'un palpeur 45 relié à la porte dès l'ouverture de celle-ci et qui sont désactivés à la fermeture de cette dernière. On peut également réaliser un mini caisson où l'air est maintenu constamment en surpression et qui est pourvu de moyens de commande d'ouverture qui sont activés dès l'ouverture de la porte ou en permanence .For this purpose, as shown in FIG. 9, it is possible, for example, to make a box 41 surrounding the slot 39 which is fed by pressurizing means 43 which are activated by detection of a feeler 45 connected to the door as soon as possible. the opening of the latter and which are deactivated when the latter closes. It is also possible to make a mini box where the air is kept constantly in overpressure and is provided with opening control means which are activated as soon as the door is opened or permanently.
Dans une variante intéressante .de la présente invention, le plancher et/ou la plafond du salon pourront être constitués d'éléments modulaires qui seront disposés et assemblés côte à côte de façon adjacente.In an interesting variant of the present invention, the floor and / or ceiling of the living room may be made of modular elements that will be arranged and assembled side by side adjacent.
Avantageusement ces modules pourront être formés de caissons dont le volume interne forme respectivement les volumes tampon de distribution d'air du plafond et du sol. Ainsi que représenté sur la figure 10, chaque caisson 50 est constitué d'une face principale horizontale 52, de forme carrée dans le présent exemple, et de faces latérales 54. Ces caissons sont assemblés, ainsi que représenté sur la figure 11, de façon adjacente, c'est-à-dire qu'ils sont jointifs par leurs faces latérales 54 de façon à remplir la surface totale ainsi que la forme globale prévue par le salon ou le module de salon dont ils doivent constituer le plancher ou le plafond.Advantageously, these modules may be formed of boxes whose internal volume respectively forms the air distribution buffer volumes of the ceiling and the ground. As shown in FIG. 10, each box 50 consists of a horizontal main face 52, of square shape in the present example, and lateral faces 54. These boxes are assembled, as shown in FIG. 11, adjacent, that is to say that they are joined by their lateral faces 54 so as to fill the total area and the overall shape provided by the living room or the living room module which they must constitute the floor or the ceiling.
On peut ainsi avoir recours à des caissons modulaires 50 de forme carrée dont la disposition reprend celle d'un local. Ils peuvent ainsi être disposés en longueur, ainsi que représenté sur la figure 11, ou en forme de L ou de T ainsi que représenté sur les figures 12 et 13. Afin de faciliter l'adéquation entre la forme et les dimensions du local avec celles correspondantes des caissons 50 certains de ceux-ci, les caissons 50a sur la figure 14, peuvent être de plus petites dimensions, par exemple moitié des caissons 50.It is thus possible to use modular boxes 50 of square shape whose arrangement is that of a local. They can thus be arranged in length, as shown in FIG. 11, or in the shape of an L or a T as shown in FIGS. 12 and 13. In order to facilitate the match between the shape and the dimensions of the room with those corresponding boxes 50 some of these, the boxes 50a in Figure 14, may be smaller, for example half of the boxes 50.
On peut bien entendu avoir recours à des caissons modulaires de formes différentes telles que par exemple rectangulaire, ou triangulaire ainsi que représenté sur la figure 15, dans laquelle les caissons 50c ont la forme de triangles équilatéraux ou de demi-triangles équilatéraux 5Od. Une telle disposition, outre l'effet esthétique produit, permet de « remplir » la forme et la surface du local dans lequel on souhaite créer un espace de détente et notamment un salon fumoir. Suivant l'invention les faces latérales 54 des caissons 50 peuvent sont percées d'ouvertures 56 destinées à permettre une libre circulation de l'air à l'intérieur des caissons à partir de l'arrivée ou des arrivées d'air. Ces ouvertures 56 sont disposées de façon telle que, lorsque les faces latérales 54 de deux caissons adjacents sont assemblées, elles se trouvent en vis à vis.One can of course use modular boxes of different shapes such as rectangular for example, or triangular as shown in Figure 15, wherein the boxes 50c have the shape of equilateral triangles or equilateral half-triangles 50d. Such an arrangement, in addition to the aesthetic effect produced, allows to "fill" the shape and the surface of the room in which one wishes to create a relaxation area and in particular a smoking room. According to the invention, the lateral faces 54 of the caissons 50 may be pierced with openings 56 intended to allow free circulation of air inside the caissons from the arrival or arrival of air. These openings 56 are arranged such that, when the lateral faces 54 of two adjacent boxes are assembled, they are opposite.
Avantageusement les caissons modulaires 50 sont pourvus de moyens de fixation permettant d' assurer leur solidarisation ainsi que leur étanchéité vis à vis de l'air. On peut ainsi faire appel à des vis, ou à des clips 55 qui sont disposés dans des logements creusés à cet effet par exemple dans les faces latérales 54, ainsi que représenté sur la figure 16. De tels clips 55 sont par exemple constitués de deux éléments complémentaires qui sont disposés en des zones des faces latérales 54 qui se trouvent en vis à vis lorsque les caissons modulaires 50 sont en place. L'un des éléments complémentaires de ces clips peut comporter une languette déformable 61 qui, lors de la mise en place, lorsque l'on applique un élément de clip sur l'élément complémentaire vient se positionner dans ce dernier de façon à bloquer tout retrait de celui-ci.Advantageously the modular boxes 50 are provided with fixing means to ensure their joining and their sealing with respect to the air. It is thus possible to use screws, or clips 55, which are arranged in housings dug for this purpose, for example in the lateral faces 54, as shown in FIG. 16. Such clips 55 consist, for example, of two complementary elements which are arranged in areas of the side faces 54 which are opposite when the modular boxes 50 are in place. One of the complementary elements of these clips may comprise a deformable tongue 61 which, when the implementation, when applying a clip member on the complementary element is positioned in the latter to block any withdrawal of it.
On pourrait bien entendu utiliser tout autre élément de fixation permettant de solidariser entre eux les différents caissons modulaires 50.One could of course use any other fastening element for securing between them the various modular boxes 50.
Par ailleurs les faces principales 52 des caissons modulaires 50 seront percées de trous 16 permettant d'injecter dans le local le flux de soufflage. Ces trous seront bien entendu du même type que ceux précédemment décrits dans le mode de mise en oeuvre d'un plancher sans caissons .Moreover, the main faces 52 of the modular caissons 50 will be pierced with holes 16 for injecting into the room the flow of blowing. These holes will of course be of the same type as those previously described in the implementation mode of a floor without boxes.
La face principale 52 pourra soit constituer la surface de marche ou, au contraire être recouverte d'une plaque 60 réalisée dans un matériau plus noble et/ou plus résistant que celui utilisé pour constituer les caissons 50. The main face 52 may either constitute the walking surface or, on the contrary be covered with a plate 60 made of a more noble material and / or stronger than that used to form the caissons 50.
