Description

La présente invention concerne un dispositif de régulation de la ventilation d'une pièce d'un bâtiment.The present invention relates to a device for regulating the ventilation of a room of a building.

On sait depuis longtemps qu'il est nécessaire de ventiler les logements ainsi que les locaux tertiaires comme les écoles ou les bureaux, pour certaines raisons techniques telles que la conservation du bâtiment, l'évacuation des pollutions spécifiques liées à la présence des occupants, l'évacuation des pollutions spécifiques liées au bâtiment lui-même, l'évacuation des pollutions spécifiques liées aux matériels ou machines utilisées dans ces locaux.It has long been known that it is necessary to break down housing as well as tertiary premises such as schools or offices, for some technical reasons such as building conservation, evacuation of specific pollution related to the presence of the occupants, evacuation of specific pollution related to the building itself, the evacuation specific pollution related to the equipment or machinery used in these local.

Par ailleurs, la maítrise de cette ventilation est nécessaire pour limiter les déperditions thermiques liées à ce renouvellement de l'air.Moreover, the control of this ventilation is necessary to limit thermal losses associated with this renewal of the air.

Les fabricants de matériels de ventilation mécanique proposent généralement des systèmes dits "simple flux" par extraction ou par insufflation, ou des systèmes dits "double flux", et permettant de remplir les fonctions principales de la ventilation citées plus haut.Manufacturers of mechanical ventilation equipment propose generally so-called "single flow" systems by extraction or insufflation, or so-called "dual flow" systems, and to fulfill the functions breakdowns mentioned above.

Un système de ventilation simple flux à extraction est caractérisé par un ensemble de composants permettant le transit de l'air de l'extérieur vers les locaux dits d'entrée d'air (pièces de vie en logement, pièces recevant une occupation humaine en locaux tertiaires), passage par les locaux de transit (circulations) puis passage vers les pièces dites de sorties d'air (ou pièces "techniques", c'est-à-dire toilettes, cuisine, salle de bain), pour être extrait par des conduits et rejeté par un ventilateur vers l'extérieur du bâtiment. Dans l'ordre de passage du flux d'air, on trouve respectivement les composants suivants: entrées d'air permettant le passage de l'air, passage de transit sous ou à travers les portes du local, bouches d'extraction autorégulées ou non, asservies à un polluant ou non, commandables ou non, un réseau de conduits d'extraction constitué de différents coudes, piquages, et conduits aboutissant en une ou plusieurs branches à un ou plusieurs ventilateurs.A simple exhaust flow ventilation system is characterized by a set of components allowing the transit of air from outside to the so-called air intake rooms (living rooms in housing, rooms receiving a human occupation in tertiary premises), transit through transit premises (circulations) then passage to the so-called parts of air outlets (or parts "techniques", ie toilets, kitchen, bathroom), to be extracted by ducts and rejected by a fan to the outside of the building. In the order of the flow of air, we find respectively the the following components: air intakes allowing the passage of air, passage of transit under or through the doors of the premises, self-regulating extraction vents or not, whether or not they are pollutant-related, controllable or not, a network of extraction ducts consisting of different bends, taps, and ducts terminating in one or more branches to one or more fans.

Dans le cas d'un système simple flux par insufflation, l'ordre des composants est inversé, on trouve non plus des entrées d'air mais généralement une sortie d'air composée d'une grille de décompression avec en complément un volet.In the case of a simple flow by insufflation system, the order of components is reversed, there are no more air inlets but generally an air outlet consisting of a decompression grid with complement a component.

Le système double flux (qui peut concerner un seul local ou un groupe de locaux) est caractérisé par un ensemble de composants assurant le balayage de l'air de l'extérieur vers les pièces d'entrée d'air, puis vers les pièces de sortie d'air pour être extrait par des conduits et rejeté par un ventilateur vers l'extérieur, l'insufflation par un ventilateur et un réseau de conduits et des bouches de diffusion d'un air extérieur éventuellement préparé thermiquement et filtré.The dual flow system (which may concern a single room or a group of premises) is characterized by a set of components ensuring the air from the outside to the air inlet and then to the pieces of air outlet to be extracted by ducts and rejected by a fan to the outside, insufflation by a fan and a network of ducts and outlets of outside air possibly prepared thermally and filtered.

Dans l'ordre de passage du flux d'air, on trouve respectivement les composants suivants: filtres, préchauffage ou rafraíchissement, ventilateur, réseau de conduits isolés ou non, grilles de diffusion, passage de transit sous ou à travers les portes du local, bouches d'extraction autorégulées ou non, asservies à un polluant ou non, commandables ou non, un réseau de conduits d'extraction constitué de différents coudes, piquages, et conduits aboutissant en une ou plusieurs branches à un ou plusieurs ventilateurs.In the order of passage of the air flow, there are respectively the following components: filters, preheating or cooling, fan, network of insulated and uninsulated conduits, diffusion grids, transit passage under or through the doors of the premises, self-regulating or unregulated extraction vents, subject to a pollutant or not, controllable or not, a network of conduits of extraction consisting of different bends, taps, and conduits leading in one or more branches to one or more fans.

Dans les locaux à fort besoin de ventilation (en particulier les locaux à fort taux d'occupation), quel que soit le système utilisé, et plus particulièrement dans le cas d'un système simple flux par insufflation ou par extraction, les entrées et sorties d'air sont très souvent difficiles à mettre en oeuvre. En effet, les débits sont tels que le nombre d'entrées d'air nécessaire ne peut pas être mis en place sans un problème d'encombrement et/ou d'esthétique.In rooms with a high need for ventilation (especially premises with a high occupancy rate), whatever the system used, and more particularly in the case of a simple flow system by insufflation or by Extraction, the entrances and exits of air are very often difficult to put into artwork. Indeed, the flow rates are such that the number of air intakes required can not be implemented without a congestion problem and / or aesthetics.

Il est de plus difficile, voire impossible, de respecter l'isolement acoustique de la façade (qui doit respecter en France les termes du décret du 09 janvier 1995 à ce sujet ou par toute autre réglementation nationale fixant un affaiblissement minimum de façade).It is difficult, if not impossible, to respect isolation acoustics of the facade (which must respect in France the terms of the decree of the January 09, 1995 in this respect or by any other national regulation establishing a minimum attenuation of facade).

Les débits dans les locaux sont, soit constants, soit modulés en fonction par exemple de la qualité de l'air intérieur. On comprend alors qu'il est difficile d'avoir une entrée d'air parfaitement adaptée puisque le débit peut varier dans le temps. Les entrées ou sorties d'air doivent être dimensionnées pour le débit maximum.The flows in the premises are either constant or modulated in function for example of indoor air quality. We understand then that he is difficult to have a perfectly adapted air intake since the flow can vary in time. Inlets or outlets must be dimensioned for the maximum flow.

L'enveloppe du bâtiment a, elle aussi, une très forte incidence sur la manière dont la ventilation est réalisée. En effet, une mauvaise réalisation du bâtiment entraíne des perméabilités résiduelles, qui prennent la forme de fuites d'air dans des interstices traversant les murs du bâtiment, et qui deviennent un parasite de la ventilation susceptible d'apporter non seulement une augmentation des pertes thermiques, en présence de vent par exemple, mais aussi une forte perturbation de la répartition de la ventilation en court-circuitant la ventilation de certaines parties du bâtiment et en empêchant la hiérarchie, locaux d'entrée d'air, locaux de transit, locaux de sortie d'air. The building envelope also has a very strong impact on how the ventilation is done. Indeed, a poor realization of building leads to residual permeabilities, which take the form of leaks air in interstices crossing the walls of the building, which become a parasite of the ventilation likely to bring not only a increased thermal losses, in the presence of wind for example, but also a strong disruption of the distribution of ventilation by shorting ventilation of certain parts of the building and preventing the hierarchy, air intake rooms, transit rooms, air outlet rooms.

L'effet du vent sur un bâtiment entraíne un débit traversant non maítrisé. Les pressions ou dépressions engendrées sur les façades modifient les débits entrants ou sortants dans les différents locaux, et peuvent créer une gêne thermique ainsi que des déperditions thermiques.The effect of wind on a building results in a non-flow through control. The pressures or depressions generated on the facades modify incoming or outgoing flows in the different premises, and can create a thermal discomfort as well as thermal losses.

Le phénomène de la gravité (tirage thermique) a aussi des effets perturbateurs très importants sur les systèmes. Dans une maison à étage par exemple, ou dans un local de grande hauteur il n'est pas rare de constater un court-circuitage des systèmes de ventilation classiques par le simple effet du tirage thermique entre les entrées d'air ou sorties d'air du bas et celle du haut du volume.The phenomenon of gravity (thermal draw) also has effects very important disrupters on the systems. In a two storey house example, or in a high-rise room it is not uncommon to see a short circuiting of conventional ventilation systems by the simple effect of thermal draw between the air intakes or the air outlets at the bottom and at the top volume.

Pour résoudre les problèmes énoncés ci-dessus, on a donc proposé des dispositifs de ventilation permettant d'asservir l'ouverture d'un ouvrant de façade à la différence de pression résultante (positive ou négative) entre le local et l'extérieur par un dispositif automatisé. L'ouvrant pouvant être soit une fenêtre motorisée soit tout autre élément commandable permettant de faire entrer ou sortir de l'air.To solve the problems stated above, we have therefore proposed ventilation devices to enslave the opening of a opening facade to the resulting pressure difference (positive or negative) between the local and the outside by an automated device. The opening can be either a motorized window or any other controllable element allowing bring in or out of the air.

Ainsi, dans des systèmes tels que celui décrit dans le document US 4 960 041, la section de passage d'air à travers les ouvrants en façade, est asservie au différentiel de pression. il gère le débit d'air entrant ou sortant, amené par un système mécanique L'objectif est de maintenir un différentiel de pression à l'intérieur du local par rapport à l'extérieur du local.Thus, in systems such as that described in US 4 960 041, the section of passage of air through the openings in frontage, is enslaved to the pressure differential. it manages the incoming or outgoing air flow, brought by a mechanical system The objective is to maintain a differential pressure inside the room relative to the outside of the room.

Néanmoins, si ce système permet de gérer correctement le niveau de ventilation du bâtiment en respectant le niveau de différentiel de pression entre l'intérieur et l'extérieur, le dispositif mis en oeuvre dans ce document relie nécessairement, grâce à des câblages électriques, les actionneurs des différents ouvrants du bâtiment, entre eux, et également à un système de ventilation par insufflation des pièces. La gestion correcte et précise des différents constituants de ce dispositif composite nécessite une très complexe et fastidieuse programmation d'une unité centrale de gestion du fonctionnement des entrées et sorties d'air. En outre, l'installation est également fastidieuse et complexe, puisqu'elle nécessite l'installation des câblages et la programmation de l'unité centrale de commande en fonction de la configuration du bâtiment.Nevertheless, if this system makes it possible to manage the level correctly ventilation of the building respecting the level of differential pressure between the inside and outside, the device implemented in this document links necessarily, thanks to electrical wiring, the actuators of the different openings of the building, between them, and also to a system of ventilation by insufflation of parts. The correct and precise management of different constituents of this composite device requires a very complex and tedious programming of a central management unit of the operation of the air inlets and outlets. In addition, the installation is as tedious and complex as it requires the installation of wiring and programming the central control unit according to the configuration of the building.

De plus, le fonctionnement du dispositif décrit ne prend absolument pas en compte la typologie des locaux traités et de leur besoin spécifique d'air neuf de ventilation (locaux d'entrée d'air, de transit ou de sortie d'air), ni le confort des usagers du bâtiment, en particulier au niveau acoustique et/ou thermique.In addition, the operation of the device described does not take absolutely not take into account the typology of the rooms treated and their specific need for air nine ventilation units (air intake, transit or air outlet rooms), or the comfort of the building users, in particular at the acoustic level and / or thermal.

Le problème sous jacent à l'invention est donc de fournir un dispositif permettant de maintenir, dans une pièce donnée d'un bâtiment, un niveau prédéterminé de pression d'air différentielle entre l'intérieur de cette pièce et l'extérieur du bâtiment, indépendamment du fonctionnement du système de ventilation mécanique contrôlée (VMC) du bâtiment, c'est-à-dire de fournir un dispositif de régulation automatique de la ventilation d'une pièce d'un bâtiment qui soit économique et facile à installer.The problem underlying the invention is therefore to provide a device for maintaining, in a given room of a building, a predetermined level of differential air pressure between the interior of this room and the outside of the building, regardless of how the controlled mechanical ventilation system (VMC) of the building, that is to say provide a device for automatically regulating the ventilation of a room of a building that is economical and easy to install.

L'objectif de l'invention est atteint avec un dispositif de régulation de la ventilation d'une pièce d'un bâtiment comprenant un dispositif de traitement de l'air d'au moins cette pièce du bâtiment.The object of the invention is achieved with a regulating device the ventilation of a part of a building including a air treatment of at least that part of the building.

Plus précisément, le dispositif selon l'invention est caractérisé en ce qu'il comprend:

  • (i) au moins un capteur différentiel de pression d'air entre l'intérieur de ladite pièce et l'extérieur du bâtiment,
  • (ii) au moins un élément ouvrant motorisé permettant de réaliser la liaison de l'intérieur de ladite pièce avec l'extérieur du bâtiment, chaque élément ouvrant étant équipé d'un moteur relié directement au capteur, et géré électroniquement par un module de gestion intégré permettant la gestion proportionnelle du degré d'ouverture/fermeture de l'élément ouvrant correspondant, en fonction de la différence entre la pression différentielle mesurée à l'intérieur de la pièce, et une valeur cible de pression différentielle prédéterminée.
    • More specifically, the device according to the invention is characterized in that it comprises:
  • (i) at least one differential air pressure sensor between the interior of said room and the outside of the building,
  • (ii) at least one motorized opening element making it possible to link the interior of said room with the outside of the building, each opening element being equipped with a motor connected directly to the sensor, and managed electronically by a management module integrated circuit allowing the proportional management of the degree of opening / closing of the corresponding opening element, as a function of the difference between the differential pressure measured inside the room, and a predetermined differential pressure target value.

    • Grâce au dispositif de l'invention, la ventilation d'une pièce d'un bâtiment est régulée, et l'on assure un débit d'air neuf en permanence, quels que soient les besoins de ventilation, les perturbations liées aux inétanchéités du bâtiment, la pression du vent contre une façade du bâtiment, ou encore le tirage thermique dans des bâtiments à plusieurs étages. La régulation s'opère indépendamment du fonctionnement du système de ventilation VMC du bâtiment, et également indépendamment du fonctionnement des autres dispositifs selon l'invention éventuellement installés dans d'autres pièces du bâtiment. Dans chaque pièce équipée d'un tel dispositif, le capteur de pression différentiel va mesurer la pression différentielle entre l'intérieur de cette pièce et l'extérieur, et va comparer cette valeur de pression différentielle à une valeur cible programmée dans un module de gestion électronique associé au moteur de l'ouvrant. Si la valeur cible est une dépression (valeur négative en Pascals), le module commandera la fermeture de l'ouvrant lorsque la pression différentielle mesurée est supérieure à la valeur cible, et l'ouverture proportionnelle lorsque la valeur de pression mesurée dans la pièce est inférieure à la valeur cible. Par ouverture proportionnelle, on entend ouverture de plus en plus importante de l'ouvrant, au fur et à mesure que la valeur mesurée s'écarte de la valeur cible.Thanks to the device of the invention, the ventilation of a room of a building is regulated, and it ensures a constant fresh air flow, which whatever the need for ventilation, the disturbances related to leaks of the building, the pressure of the wind against a building facade, or the thermal draft in multi-storey buildings. Regulation operates regardless of the operation of the VMC ventilation system of the building, and also independently of the operation of others devices according to the invention possibly installed in other rooms of the building. In each room equipped with such a device, the pressure sensor differential will measure the differential pressure between the inside of this piece and outside, and will compare this differential pressure value to a value programmed target in an electronic management module associated with the engine of the opening. If the target value is a depression (negative value in Pascals), the module will control the closing of the opening when the pressure differential measured is greater than the target value, and the opening proportional when the pressure value measured in the room is less than the target value. Proportional opening means opening more and more important of the opening, as the value measured value deviates from the target value.

    Le fonctionnement sera inverse lorsque la valeur cible de pression différentielle est une surpression, c'est-à-dire une valeur positive.Operation will be reversed when the pressure target value Differential is an overpressure, that is, a positive value.

    Par exemple, les valeurs cibles de pression différentielle seront programmées négatives dans le cas d'une VMC simple flux par extraction, et positives dans le cas où le bâtiment est équipé d'une VMC simple flux par insufflation. Dans le cas où le bâtiment est équipé d'une VMC double flux, la valeur cible programmée sera de préférence négative, mais pourra dans certains cas d'espèce particuliers être au contraire légèrement positive.For example, the differential pressure target values will be programmed negative in the case of a single VMC flux by extraction, and positive in the event that the building is equipped with a single VMC flows by insufflation. In the case where the building is equipped with a dual flow VMC, the programmed target value will preferably be negative, but may be some particular cases are, on the contrary, slightly positive.

    Le dispositif dans chaque pièce maintient ainsi un différentiel de pression constant entre l'intérieur et l'extérieur de la pièce.The device in each room thus maintains a differential of constant pressure between the inside and the outside of the room.

    Il est à noter que le dispositif de l'invention est particulièrement simple dans sa structure et dans sa mise en oeuvre. En effet, ce dispositif comprend un moteur géré électroniquement par un module de gestion tel qu'un circuit imprimé intégré, un capteur de pression différentiel entre l'intérieur d'une pièce et l'extérieur du bâtiment. On pourra prévoir d'installer le moteur et le capteur sur un ouvrant (par exemple une fenêtre) existant, ou bien de fournir à l'installation, un ouvrant motorisé avec un dispositif selon l'invention (moteur et capteur de pression différentiel).It should be noted that the device of the invention is particularly simple in its structure and its implementation. Indeed, this device includes a motor managed electronically by a management module such as a integrated circuit board, a differential pressure sensor between the inside of a room and the exterior of the building. We can plan to install the engine and the sensor on an opening (for example an existing window), or to provide the installation, a motorized opening with a device according to the invention (motor and differential pressure sensor).

    Il faut remarquer qu'il y a une interaction entre les différents ouvrants et la VMC, sans communication explicite entre les différents éléments, mais qui sont reliés fonctionnellement par le système de ventilation. Le résultat de la régulation sur l'ensemble de plusieurs pièces est cohérent, bien que les éléments constitués par les ouvrants et leurs motorisations respectives soient autonomes.It should be noted that there is an interaction between the different opening and the VMC, without explicit communication between the different elements, but which are functionally connected by the ventilation system. The result regulation on the whole of several pieces is consistent, although the elements constituted by the doors and their respective engines are autonomous.

    Selon une forme particulièrement préférée de l'invention, le dispositif comprend en outre un capteur de présence relié au moteur, et participant à la gestion du degré d'ouverture/fermeture de l'élément ouvrant correspondant, de manière à modifier le seuil de pression et ainsi augmenter le degré d'ouverture ou de fermeture de l'ouvrant motorisé lorsqu'une présence est détectée dans la pièce.According to a particularly preferred form of the invention, the device further comprises a presence sensor connected to the motor, and participating in the management of the opening / closing degree of the opening element corresponding, so as to modify the pressure threshold and thus increase the degree of opening or closing of the motorized opening when a presence is detected in the room.

    Selon une première variante d'exécution de l'invention, le bâtiment est équipé d'un dispositif de traitement de l'air qui est un dispositif de ventilation mécanique contrôlée - habituellement appelé "VMC" ― simple flux à extraction, la valeur cible de pression différentielle programmée dans le circuit électronique de gestion du moteur de l'ouvrant, étant alors négative. Dans ce cas, on vise à maintenir la pièce dans laquelle le dispositif selon l'invention est installé, en dépression par rapport à l'extérieur du bâtiment.According to a first variant embodiment of the invention, the building is equipped with an air treatment device that is a device of controlled mechanical ventilation - usually called "VMC" - simple flow to extraction, the target value of differential pressure programmed in the circuit electronic engine management of the opening, being then negative. In this In this case, it is intended to maintain the part in which the device according to the invention is installed, in depression with respect to the outside of the building.

    Selon une seconde variante d'exécution de l'invention, le dispositif de traitement de l'air qui équipe le bâtiment est un dispositif VMC simple flux à insufflation, la valeur cible de pression différentielle programmée dans le circuit électronique de gestion du moteur de l'ouvrant, étant alors positive.According to a second variant embodiment of the invention, the device of air treatment that equips the building is a simple VMC device flows to insufflation, the target value of differential pressure programmed in the circuit electronic engine management of the opening, then being positive.

    Selon une troisième variante d'exécution de l'invention, le dispositif de traitement de l'air est un dispositif de ventilation VMC double flux. Dans ce cas, la valeur cible de pression différentielle qui sera programmée dans le circuit électronique de gestion du moteur de l'ouvrant, sera au choix positive ou négative, par choix d'installation, et dans tous les cas, cette valeur cible sera très peu différente de la pression extérieure.According to a third variant embodiment of the invention, the device of air treatment is a VMC dual flow ventilation device. In this case, the differential pressure target value that will be programmed into the electronic engine management circuit of the opening, will be the positive choice or negative, by choice of installation, and in any case, this target value will be very little different from the outside pressure.

    Dans tous les cas, les éléments ouvrants sont choisis parmi les fenêtres, plénums, caissons, volets de surpression/dépression, registres, et/ou sorties de ventilation en toiture.In all cases, the opening elements are chosen from the windows, plenums, caissons, pressure / vacuum flaps, dampers, and / or ventilation outlets on the roof.

    Dans les locaux à fort besoin de ventilation, un des avantages de l'invention est d'utiliser de préférence, pour réaliser la fonction entrée/sortie d'air, un élément existant de la façade dans le cas de l'utilisation d'un ouvrant déjà en place. On s'affranchit du problème de mise en oeuvre d'un nombre important de modules d'entrée d'air ou d'un élément en façade pas toujours très esthétique.In rooms with a high need for ventilation, one of the advantages of the invention is preferably to use, to perform the input / output function of air, an existing element of the facade in the case of the use of an opening already in place. We get rid of the problem of implementing a number important of air inlet modules or a facade element not always very aesthetic.

    Avec le dispositif de l'invention, dans la pièce, il n'y a plus d'entrée d'air restant toujours ouverte quel que soit le besoin en air neuf de cette pièce.With the device of the invention, in the room, there is no entry air remaining always open regardless of the need for fresh air in this room.

    Ce dispositif a également pour avantage d'inhiber l'effet de l'air traversant en cas de vent. On s'affranchit du courant d'air dans un local soumis à l'effet du vent, réduisant ainsi un débit traversant et donc les déperditions thermiques et un inconfort lié à un flux d'air froid non maítrisé.This device also has the advantage of inhibiting the effect of air crossing in case of wind. It avoids the flow of air in a local subject to the effect of the wind, thus reducing through-flow and therefore losses thermal and discomfort related to a flow of cold air unmanaged.

    L'invention permet de compenser dans une certaine mesure les conséquences, en termes de débit d'air, d'éventuels défauts d'étanchéité à l'air du bâtiment et donc d'éviter une ouverture systématique de l'ouvrant pour l'entrée ou la sortie d'air dans certaines pièces.The invention makes it possible to compensate to a certain extent the consequences, in terms of air flow, of any airtightness defects of the building and thus to avoid a systematic opening of the opening for the entrance or exit of air in certain rooms.

    L'invention permet de compenser les défauts inhérents au tirage thermique constatés dans les systèmes simple flux par extraction, où l'entrée d'air des étages se comporte comme une sortie d'air du fait du tirage thermique supérieur à la dépression crée par le dispositif spécifique de ventilation.The invention makes it possible to compensate for the defects inherent in the draw observed in single flow systems by extraction, where the input of air stages behaves like an air outlet due to the thermal draw greater than the depression created by the specific ventilation device.

    En complément, le dispositif selon l'invention offre la possibilité d'un rafraíchissement nocturne pendant la saison estivale, par ouverture plus importante ou totale des ouvrants.In addition, the device according to the invention offers the possibility of a night refresh during the summer season, by opening more large or total opening.

    Pour sa bonne compréhension, l'invention va à présent être décrite en détail, en référence au dessin schématique annexé, représentant à titre d'exemple non limitatif, deux formes particulières d'exécution d'un dispositif de régulation de la ventilation selon l'invention.

  • La figure 1 est une vue schématique d'un bâtiment équipé d'un dispositif selon l'invention, avec capteur de présence, dans laquelle toutes les pièces du bâtiment sont occupées, sans effet de vent à l'extérieur du bâtiment ;
  • La figure 2 est une vue similaire à la figure 1, dans laquelle toutes les pièces du bâtiment sont occupées, avec un effet de vent à l'extérieur du bâtiment ;
  • La figure 3 est une vue schématique similaire à la figure 1, dans laquelle une pièce du bâtiment est inoccupée, sans effet de vent à l'extérieur du bâtiment.
  • La figure 4 est une vue schématique d'un bâtiment d'habitation à plusieurs étages, équipé d'un système de VMC par extraction, et dont les pièces sont chacune équipée d'un dispositif selon l'invention, sans capteur de présence.
    • For a good understanding, the invention will now be described in detail, with reference to the appended schematic drawing, showing by way of nonlimiting example, two particular embodiments of a ventilation control device according to the invention. invention.
  • Figure 1 is a schematic view of a building equipped with a device according to the invention, with presence sensor, in which all parts of the building are occupied, without wind effect outside the building;
  • Figure 2 is a view similar to Figure 1, in which all parts of the building are occupied, with a wind effect outside the building;
  • Figure 3 is a schematic view similar to Figure 1, in which a room of the building is unoccupied, no wind effect outside the building.
  • Figure 4 is a schematic view of a multi-storey residential building, equipped with a VMC extraction system, and whose parts are each equipped with a device according to the invention, without presence sensor.

    • Dans les exemples qui suivent, cités à titre non limitatif, on considèrera que chacune des pièces du bâtiment est équipée d'un dispositif 1 selon l'invention. On pourrait néanmoins envisager un bâtiment dans lequel seule une pièce, ou certaines pièces soi(en)t équipée(s), auquel cas, seule la régulation de la ventilation d'air neuf par gestion de l'ouverture/fermeture des ouvrants en façade dans cette ou ces pièce(s), serait assurée. In the examples which follow, cited in a non-limiting way, consider that each room of the building is equipped with a device 1 according to the invention. One could nevertheless consider a building in which only one part, or some parts, equipped with them, in which case only the regulation of fresh air ventilation by management of the opening / closing of front opening in this or these room (s), would be assured.

    Dans un premier exemple représenté aux figures 1 à 3, le bâtiment est un bâtiment de plein pied, comportant deux pièces, et muni d'un dispositif de ventilation centralisée (VMC) à insufflation.In a first example shown in FIGS. 1 to 3, the building is a one-storey building, with two rooms, and equipped with a centralized ventilation system (VMC).

    Ce bâtiment comporte deux pièces 2, chacune disposant d'un élément ouvrant 3, les deux pièces communiquant par une ouverture 4, constituée par une grille de transfertThis building has two rooms 2, each with a opening element 3, the two parts communicating through an opening 4, constituted by a transfer grid

    Ce dispositif 1 comprend, pour chaque pièce 2 du bâtiment, d'une part un capteur différentiel de pression d'air 6 entre l'intérieur de ladite pièce et l'extérieur du bâtiment, et d'autre part un élément ouvrant motorisé 3 disposé en façade dudit bâtiment permettant de réaliser la liaison de l'intérieur de ladite pièce avec l'extérieur du bâtiment, chaque élément ouvrant comprenant un moteur 5 relié au capteur 6, permettant la gestion proportionnelle du degré d'ouverture/fermeture de l'élément ouvrant correspondant, en fonction de la différence entre la pression différentielle mesurée à l'intérieur de la pièce, et une valeur cible prédéterminée.This device 1 comprises, for each piece 2 of the building, a a differential air pressure sensor 6 between the inside of the said part and outside the building, and secondly a motorized opening element 3 arranged on the facade of said building enabling the connection of the interior of said room with the exterior of the building, each opening element comprising a motor 5 connected to the sensor 6, allowing the proportional management of the degree opening / closing of the corresponding opening element, depending on the difference between the differential pressure measured inside the room, and a predetermined target value.

    Dans le présent exemple, le dispositif 1 comprend en outre un capteur de présence 9 relié au moteur 5, qui participe à la gestion du degré d'ouverture/fermeture de l'élément ouvrant correspondant, de manière à augmenter le degré d'ouverture ou de fermeture de l'ouvrant motorisé lorsqu'une présence est détectée dans la pièce.In the present example, the device 1 further comprises a presence sensor 9 connected to the motor 5, which participates in the management of the degree opening / closing of the corresponding opening element, so as to increase the degree of opening or closing of the motorized opening when a presence is detected in the room.

    Les différents capteurs 6, 9 sont reliés directement au moteur 5 de chaque élément ouvrant 3, et un module de gestion - prenant la forme d'un circuit imprimé ― est associé à chaque moteur et permet de gérer la commande et le degré d'ouverture ou de fermeture de l'élément ouvrant correspondant, en fonction d'une part des pressions intérieure et extérieure détectées, de la présence ou non de personnes dans la pièce correspondante, et d'autre part en fonction de valeurs prédéterminées pour la surpression désirée dans chaque pièce du bâtiment. On notera que dans le présent exemple, on souhaite mettre chaque pièce en surpression car le bâtiment est équipé d'un système de VMC par insufflation. Dans le cas contraire d'une ventilation mécanique par extraction, la valeur cible programmée dans le dispositif de l'invention sera une valeur de pression différentielle négative, de manière à maintenir la pièce en dépression.The different sensors 6, 9 are connected directly to the motor 5 of each opening element 3, and a management module - taking the form of a printed circuit - is associated with each motor and allows to manage the order and the degree of opening or closing of the corresponding opening member, function of the detected internal and external pressures, the presence or not of persons in the corresponding room, and secondly according to predetermined values for the desired overpressure in each piece of the building. Note that in this example, wish to put each piece in overpressure because the building is equipped with a VMC system by insufflation. In the opposite case of a ventilation mechanical extraction, the programmed target value in the device of the invention will be a negative differential pressure value, so as to keep the room depressed.

    Il est à noter ici, de manière tout à fait importante, que grâce au capteur de présence situé dans chaque pièce du bâtiment équipée d'un dispositif selon l'invention, il est facile de réguler efficacement la ventilation tout en maintenant un niveau acoustique très confortable. En effet, l'élément ouvrant d'une pièce donnée du bâtiment sera ouvert pour assurer le renouvellement d'air, prioritairement lorsque cette pièce est inoccupée. Son ouverture sera toujours liée à la pression. La pression sera alors inférieure dans les pièces occupées, l'élément ouvrant sera alors vraisemblablement fermé dans la pièce occupée, afin de limiter le niveau sonore dû à la circulation d'air et au bruit provenant de l'extérieur du bâtiment.It should be noted here, quite significantly, that thanks to the presence sensor located in each room of the building equipped with a device according to the invention, it is easy to effectively regulate ventilation while maintaining a very comfortable acoustic level. Indeed, the element opening of a given room of the building will be opened to ensure the air renewal, primarily when this room is unoccupied. His opening will always be related to the pressure. The pressure will then be lower in occupied rooms, the opening element will then probably be closed in the occupied room, in order to limit the noise level due to traffic air and noise from outside the building.

    Comme cela est représenté au dessin, le système de ventilation 8 (VMC) installé dans le bâtiment est un dispositif simple flux à insufflation. Il se compose d'une centrale de ventilation qui insuffle de l'air neuf à l'intérieur du bâtiment et le distribue aux différentes pièces du bâtiment grâce à un réseau de conduites. Il est à noter que le système de ventilation est autonome et indépendant du dispositif de l'invention.As shown in the drawing, the ventilation system 8 (VMC) installed in the building is a simple flow insufflation device. He is consists of a ventilation unit that blows fresh air into the interior of the building. building and distributes it to different parts of the building through a network of pipes. It should be noted that the ventilation system is autonomous and independent of the device of the invention.

    Les éléments ouvrants sont choisis parmi les fenêtres, plénums, caissons, volets de surpression/dépression, registres, et/ou sorties de ventilation en toiture. Dans l'exemple décrit ici et comme représenté au dessin, les ouvrants sont des fenêtres coulissantes, dont l'ouverture et la fermeture par coulissement le long d'un rail (non représenté au dessin) sont commandés par le moteur 5.The opening elements are chosen from windows, plenums, caissons, pressure / vacuum flaps, registers, and / or outputs of ventilation on the roof. In the example described here and as shown in the drawing, the openings are sliding windows, the opening and closing by sliding along a rail (not shown in the drawing) are controlled by the engine 5.

    Dans le présent exemple, l'ouverture et la fermeture des éléments ouvrants 3 est gérée par le dispositif de l'invention, de manière à maintenir les pièces 2 du bâtiment en surpression par rapport à l'extérieur, afin de maintenir une circulation d'air depuis la VMC, à travers chaque pièce, vers l'extérieur du bâtiment. Dans ce cas, malgré la bonne étanchéité des éléments ouvrants du bâtiment, on sait qu'une certaine quantité d'air s'échappe à travers les parois du bâtiment, entre l'intérieur et l'extérieur de celui-ci, et même d'une pièce à l'autre, comme cela est représenté symboliquement au dessin par des flèches en pointillés.In this example, opening and closing elements opening 3 is managed by the device of the invention, so as to maintain the parts 2 of the building in overpressure with respect to the outside, in order to maintain a circulation of air from the VMC, through each room, to the outside of the building. In this case, despite the good sealing of the opening elements of the building, we know that a certain amount of air escapes through the walls of the building, between the inside and the outside of it, and even from one room to the other, as symbolically represented in the drawing by arrows with dots.

    Différents cas de figure du fonctionnement du dispositif selon l'invention dans le présent exemple, vont à présent être décrits en référence aux figures 1 à 3.Different cases of the operation of the device according to the invention in the present example, will now be described by reference in Figures 1 to 3.

    Dans le cas représenté à la figure 1, toutes les pièces du bâtiment sont occupées, et le dispositif de ventilation 8 met en surpression ces différentes pièces par insufflation d'air frais en provenance de l'extérieur, comme cela est représenté symboliquement par deux flèches en provenance des conduites de ventilation. In the case shown in Figure 1, all parts of the building are occupied, and the ventilation device 8 puts overpressure these different parts by blowing fresh air from outside, as is represented symbolically by two arrows coming from ventilation ducts.

    Dans ce cas, les éléments ouvrants 3 de chaque pièce 2 du bâtiment qui est équipée d'un dispositif 1 sont ouverts, mais la section (ou degré) d'ouverture est faible pour chacun d'eux. L'air circule à travers le bâtiment de manière globalement identique pour chaque pièce d'entrée d'air.In this case, the opening elements 3 of each piece 2 of the building that is equipped with a device 1 are open, but the section (or degree) is low for each of them. Air flows through the building in a substantially identical manner for each air inlet part.

    Dans le cas représenté à la figure 2, le bâtiment est soumis à un vent latéral. L'effet du vent est différent suivant l'orientation des façades. Les façades au vent - qui est représenté par une triple flèche à la figure 2 - sont en surpression, les façades sous le vent sont en dépression d'air. Les pièces situées du coté de la façade au vent se retrouvent alors à une pression inférieure à la pression extérieure. Dans ce cas il est inutile d'ouvrir l'élément ouvrant 3a en façade de la pièce correspondante 2a, comme cela est représenté à la figure 2. En effet, ceci aurait pour effet de faire entrer de l'air et non pas d'en faire sortir, et d'apporter un inconfort thermique.In the case shown in Figure 2, the building is subject to a lateral wind. The effect of the wind is different depending on the orientation of the facades. The wind facades - which is represented by a triple arrow in Figure 2 - are overpressure, the facades under the wind are in air depression. Rooms located on the side of the windward facade are then at a pressure less than the external pressure. In this case it is useless to open the element opening 3a in front of the corresponding part 2a, as is shown in Figure 2. Indeed, this would have the effect of bringing in air and not to get out, and bring thermal discomfort.

    En revanche, les pièces situées sous le vent, sont en dépression d'air par rapport à l'extérieur du bâtiment, et il est alors nécessaire d'ouvrir l'ouvrant 3b pour permettre l'évacuation de l'air vicié. Dans ce cas, le vent perturbe beaucoup moins la ventilation du bâtiment et le confort des occupants que dans le cas d'éléments ouvrants dont l'ouverture / fermeture n'est pas asservie à la différence de pression détectée entre le bâtiment et l'extérieur. Le local d'entrée d'air se comporte également ici comme un local de sortie d'air. En outre, grâce à la présente invention, les déperditions thermiques sont réduites puisque l'on optimise le débit d'air frais circulant à travers le bâtiment (évitant aussi une gêne thermique pour les occupants).On the other hand, the parts located under the wind, are in depression from the outside of the building, and it is then necessary to open the opening 3b to allow the evacuation of stale air. In this case, the wind much less disrupts building ventilation and occupant comfort than in the case of opening elements whose opening / closing is not enslaved to the difference in pressure detected between the building and the outside. The Local air intake also behaves here as a local air outlet. In addition, thanks to the present invention, the heat losses are reduced by optimizing the flow of fresh air flowing through the building (also avoiding thermal discomfort for the occupants).

    Suivant les débits insufflés et suivant l'effet du vent, la section de passage de la sortie d'air ainsi que son positionnement est optimisé, comme cela est représenté aux figures 1 et 2.According to the inflated flows and the effect of the wind, the section of passage of the air outlet as well as its positioning is optimized, as this is shown in Figures 1 and 2.

    Ainsi, on notera que dans le cas représenté à la figure 1, le bâtiment n'est pas soumis à un effet de vent, et donc les éléments ouvrants 3 ont un degré d'ouverture relativement faible. En revanche, en cas de vent comme cela est illustré à la figure 2, l'élément ouvrant situé sous le vent a un degré d'ouverture beaucoup plus important.Thus, it will be noted that in the case represented in FIG. building is not subject to a wind effect, and therefore the opening elements 3 have a relatively low degree of opening. On the other hand, in case of wind as shown in Figure 2, the leeward opening element has a much greater degree of openness.

    Si toutes les pièces ne sont pas occupées comme cela est représenté à la figure 3, la fenêtre 3b de la pièce vide 2b sera ouverte de manière préférentielle, également en fonction de la pression différentielle mesurée entre l'intérieur et l'extérieur du bâtiment. Ceci aura pour effet d'évacuer ou faire entrer l'air et de faire éventuellement baisser la pression dans les pièces occupées 2a - selon les perméabilités, grilles de transfert ou ouvertures entre les différentes pièces ―. La pression y étant plus faible, il ne sera alors pas utile d'ouvrir l'élément ouvrant 3a de la pièce occupée 2a, comme cela est représenté à la figure 3.If all the rooms are not occupied as is shown in FIG. 3, the window 3b of the empty part 2b will be opened from preferentially, also depending on the differential pressure measured between the interior and exterior of the building. This will have the effect evacuate or bring in air and possibly lower the pressure in occupied rooms 2a - according to permeabilities, transfer grids or openings between the different rooms -. The pressure is lower there, it does not then will not be useful to open the opening element 3a of the occupied part 2a, as shown in Figure 3.

    Dans le cas contraire, l'ouverture sera optimisée (car la pression d'air y est plus faible), afin d'obtenir ainsi un confort (thermique et acoustique) plus élevé, comme cela est représenté à la figure 3. Dans tous les cas de figure de fonctionnement de l'invention, les algorithmes multicritères de régulation, c'est-à-dire les paramètres de programmation intégrés au circuit imprimé faisant la liaison entre les différents capteurs et le moteur 5 de chaque élément ouvrant, seront adaptés suivant le type de ventilation: simple flux par insufflation ou par extraction, double flux, débits fixes ou modulés.Otherwise, the opening will be optimized (because the pressure air is weaker), to obtain comfort (thermal and acoustic) higher, as shown in Figure 3. In all cases of operating figure of the invention, the multicriterion algorithms of regulation, that is to say the programming parameters integrated into the circuit printed form linking the different sensors and the motor 5 of each opening element, will be adapted according to the type of ventilation: simple flow by insufflation or extraction, double flow, fixed or modulated flow rates.

    Dans un second exemple représenté à la figure 4, le bâtiment est un bâtiment à étages, comportant trois pièces superposées 2a, 2b, 2c (numérotées du bas vers le haut au dessin), et muni d'un dispositif de ventilation centralisée (VMC) à extraction comprenant une unités d'aspiration et une extraction commune en partie haute. Dans ce second exemple, le dispositif selon l'invention installé dans chaque pièce (2a, 2b et 2c) ne comporte pas de capteur de présence, mais uniquement un ouvrant (notés respectivement 3a, 3b et 3c au dessin pour chacune des pièces du bâtiment) - par exemple une fenêtre coulissante ― dont l'ouverture et la fermeture sont commandées par un moteur 5, ce dernier étant relié à un capteur de pression différentiel 6. Le fonctionnement du dispositif est identique à celui décrit ci-avant dans le premier exemple. Comme dans le premier exemple, on a représenté les fuites d'air dues à la perméabilité du bâtiment par des flèches en traits pointillés. On aura noté que, dans le présent exemple, les entrées d'air dues à la perméabilité du bâtiment se font de l'extérieur vers l'intérieur du bâtiment, puisque l'intérieur de chaque pièce du bâtiment est en dépression par rapport à l'extérieur (la ventilation des pièces est réalisée en extraction d'air).In a second example shown in Figure 4, the building is a multi-storey building with three superposed rooms 2a, 2b, 2c numbered from bottom to top in the drawing), and equipped with a extraction centralized ventilation (VMC) comprising a suction unit and a common extraction in the upper part. In this second example, the device according to the invention installed in each piece (2a, 2b and 2c) does not have any presence sensor, but only an opening (denoted respectively 3a, 3b and 3c to the drawing for each piece of the building) - for example a sliding window - whose opening and closing are controlled by a motor 5, the latter being connected to a differential pressure sensor 6. operation of the device is identical to that described above in the first example. As in the first example, air leaks are shown due to the permeability of the building by arrows in dashed lines. We'll have noted that, in this example, the air intakes due to the permeability of the building are from the outside to the inside of the building, since the interior of each room of the building is in depression with respect to the outside (the ventilation of the rooms is performed in air extraction).

    Dans ce logement, la ventilation est continue et permanente. Dans l'exemple décrit à la figure 4, le besoin de ventilation a été défini comme étant identique aux trois niveaux, et de ce fait, chacune des pièces des trois niveaux a été équipée d'un dispositif selon l'invention.In this dwelling, ventilation is continuous and permanent. In the example described in Figure 4, the need for ventilation has been defined as being identical to the three levels, and therefore, each of the three levels has been equipped with a device according to the invention.

    Néanmoins, les pressions différentielles aux différents niveaux sont différentes car elles sont liées, entre autres, à l'altitude des entrées d'air (représentées par des flèches en trait plein situées au niveau des ouvrants en façade et orientées de l'extérieur du bâtiment vers l'intérieur de celui-ci). La dépression d'air dans chaque pièce par rapport à l'extérieur, sera plus importante au fur et à mesure que l'on descend dans le bâtiment. Dans ce cas, dans chaque pièce du bâtiment, le dispositif selon l'invention va permettre d'optimiser la section de passage de l'ouvrant 2a, 2b ou 2c, afin d'avoir un débit identique dans toutes les pièces, et d'éviter que l'entrée d'air de la pièce du haut 2c ne devienne à un moment une sortie d'air, ce qui peut se produire quand la dépression dans le logement lié au système de ventilation devient inférieure au tirage thermique entre l'entrée d'air du bas et celle du haut.Nevertheless, the differential pressures at different levels are different because they are related, inter alia, to the altitude of the air intakes (represented by arrows in solid lines located at the level of the openings in facade and oriented from the outside of the building to the interior of it). The air depression in each room relative to the outside, will be more important as you go down into the building. In that case, in each room of the building, the device according to the invention will allow optimize the passage section of the opening 2a, 2b or 2c, in order to have a same flow rate in all rooms, and to prevent the entry of air from the room from the top 2c does not become at one time an air outlet, which can occur when the depression in the housing related to the ventilation system becomes lower than the thermal draw between the bottom air inlet and the top air inlet.

    Dans chaque pièce, l'effet du vent et le tirage thermique seront prises en compte par le dispositif selon l'invention, grâce à la mesure de pression par le capteur de pression différentiel. De ce fait, on peut dans certains cas avoir une entrée d'air (particulièrement celle du bas) pratiquement fermée. Dans ce cas, le débit est assuré par une dépression plus importante sur une ouverture minimale, inversement à l'étage, le débit est garantie avec une faible dépression et une ouverture plus importante. Comme on l'aura compris à l'aide des deux exemples ci-dessus, l'invention fournit un dispositif simple dans sa structure, qui puisse être installé pièce par pièce dans un bâtiment, en fonction du type de ventilation mécanique déjà installé dans ce bâtiment. Ainsi par exemple dans le cas d'un bâtiment équipé en VMC simple flux par insufflation, seules les pièces d'entrée d'air seront équipées du dispositif selon l'invention, à l'exception des pièces de transit et de sortie d'air.In each room, the effect of the wind and the thermal draft will be taken into account by the device according to the invention, thanks to the measurement of pressure by the differential pressure sensor. As a result, we can some cases have an air inlet (especially the bottom one) practically closed. In this case, the flow is ensured by a larger depression on a minimum opening, inversely upstairs, the flow is guaranteed with a weak depression and a larger opening. As we will have understood from the two examples above, the invention provides a device simple in its structure, which can be installed piece by piece in a building, depending on the type of mechanical ventilation already installed in this building. For example, in the case of a building equipped with simple VMC flow by insufflation, only the air inlet parts will be equipped with device according to the invention, with the exception of transit and air outlet parts.

    Il va de soi que l'invention n'est pas limitée à la forme de réalisation décrite ci-dessus à titre exemple mais qu'elle en embrasse au contraire toutes les variantes.It goes without saying that the invention is not limited to the embodiment described above as an example but that it encompasses all the variants.
