Description

DISPOSITIF DE COMMANDE COMBINE D'EVACUATION D'AIR DE
VENTILATION ET DE PRODUITS DE COMBUSTION D'APPAREILS A GAZ
La présente invention a trait à l'évacuation des produits de combustion d'appareils à gaz et plus particulièrement de chaudières et de à gaz équipant des appartements d'un immeuble collectif.COMBINED AIR EXHAUST CONTROL DEVICE
VENTILATION AND COMBUSTION PRODUCTS OF GAS APPLIANCES
The present invention relates to the evacuation of the combustion products of gas appliances and more particularly of boilers and gas equipments of apartments in a collective building.

De tels immeubles sont, conformément à la réglementation, munis de conduits de ventilation, par exemple des conduits de type shunt, auxquels sont raccordés, d'une part, les conduits d'évacuation des fumées et gaz brutes de chaque appareil à gaz et, d'autre part, des sorties d'air d'aération de certaines pièces des logements. Such buildings are, in accordance with the regulations, provided with ventilation ducts, for example shunt type ducts, to which are connected, on the one hand, the flue gas and raw gas exhaust ducts of each gas appliance and, on the other hand, ventilation air outlets of certain rooms in the accommodation.

Ces conduits de ventilation sont soit simplement et directement mis à l'atmosphère, l'évacuation s'effectuant par tirage naturel, soit connectés à un système d'extraction mécanique, dénommée ventilation mécanique contrôlée. These ventilation ducts are either simply and directly vented to the atmosphere, evacuation taking place by natural draft, or connected to a mechanical extraction system, called controlled mechanical ventilation.

Dans ce dernier cas et conformément à la réglementation, en cas de panne du système d'extraction mécanique, la combustion des appareils à gaz doit tre automatiquement arrtée. In the latter case and in accordance with the regulations, in the event of a breakdown of the mechanical extraction system, the combustion of gas appliances must be automatically stopped.

Pour éviter un tel arrt générât et automatique, on pourrait envisager de ne raccorder au système extracteur mécanique que les parties des conduits de ventilation affectées à la seule aération des pièces, mais ce serait ainsi priver les conduits d'évacuation des fumées et gaz brutes de tout tirage forcé. To avoid such a general and automatic shutdown, it could be envisaged to connect to the mechanical extractor system only the parts of the ventilation ducts assigned to the only ventilation of the rooms, but this would thus deprive the exhaust pipes of smoke and raw gases from any forced draw.

La présente invention vise précisément à remédier à ces inconvénients en proposant un dispositif permettant d'équiper à la fois les conduits d'évacuation des fumées et gaz brutes et les conduits d'aération d'un système d'extraction mécanique tout en satisfaisant en toutes circonstances aux exigences de la réglementation sans pour autant entraîner, en cas de panne du système d'extraction mécanique, l'arrt de la combustion des appareils à gaz. The present invention aims precisely to remedy these drawbacks by proposing a device making it possible to equip both the smoke and raw gas exhaust pipes and the ventilation pipes with a mechanical extraction system while satisfying all circumstances to regulatory requirements without, in the event of a breakdown of the mechanical extraction system, causing the combustion of gas appliances to stop.

A cet effet, l'invention a pour objet un dispositif de commande combinée d'évacuation d'air de ventilation et de produits de combustion d'appareils à gaz, en particulier d'immeubles d'habitation collective comportant des conduits de ventilation regroupant chacun les conduits d'évacuation des fumées et gaz brûlés et d'air de ventilation d'au moins certaines pièces des logements, lesdits conduits de ventilation étant reliés à un dispositif d'extraction mécanique, caractérisé en ce qu'il comprend des moyens de mise à l'atmosphère d'au moins les conduits d'évacuation des fumées et gaz brûlés des conduits de ventilation, susceptibles de deux états stables, I'un d'ouverture, I'autre de fermeture totale, des moyens de commande desdits moyens de mise à l'atmosphère dans les positions de fermeture et d'ouverture, respectivement lors des mise en service ou hors service du dispositif d'extraction mécanique et des moyens sensibles à la pression régnant dans le circuit du dispositif d'extraction mécanique susceptibles de générer, lorsque ladite pression tombe en dessous d'un seuil prédéterminé, réglable, un signal mettant lesdits moyens de mise à l'atmosphère dans ledit état d'ouverture. To this end, the invention relates to a combined control device for evacuating ventilation air and combustion products from gas appliances, in particular collective apartment buildings comprising ventilation ducts each grouping the smoke and burnt gas and ventilation air evacuation ducts for at least certain parts of the accommodation, said ventilation ducts being connected to a mechanical extraction device, characterized in that it comprises means for placing to the atmosphere of at least the smoke and burnt gas discharge ducts of the ventilation ducts, capable of two stable states, one of opening, the other of completely closing, means for controlling said means of venting in the closed and open positions, respectively when the mechanical extraction device and the pressure-sensitive means prevailing in the circuit are put into service or out of service mechanical extraction device capable of generating, when said pressure falls below a predetermined, adjustable threshold, a signal putting said means for venting into said opening state.

Suivant un mode de réalisation, lesdits moyens de mise à l'atmosphère des conduits de ventilation sont constitués, pour chaque conduit, d'un caisson chapeautant le conduit, divisé en deux compartiments, I'un affecté au conduit d'évacuation des fumées et gaz brûlés et, I'autre affecté aux conduits d'aération les deux compartiments étant reliés audit dispositif d'extraction mécanique, cependant que ledit compartiment affecté aux fumées et gaz brutes est muni d'un organe d'obturation à deux positions, d'ouverture et de fermeture. According to one embodiment, said means for venting the ventilation ducts consist, for each duct, of a box covering the duct, divided into two compartments, one assigned to the flue exhaust duct and burnt gases and, the other assigned to the ventilation ducts the two compartments being connected to said mechanical extraction device, while said compartment assigned to smoke and raw gases is provided with a shutter member with two positions, opening and closing.

Ledit organe d'obturation est avantageusement constitué par une grille à lames orientables actionnées par un moyen relié auxdits moyens de commande et auxdits moyens générant le signal de mise à l'atmosphère. Said shutter member is advantageously constituted by a grid with adjustable blades actuated by means connected to said control means and to said means generating the signal to vent.

De préférence, ledit moyen d'actionnement comprend un vérin maintenant, en position de relâchement, la grille en position d'ouverture et un électro-aimant maintenant, lorsqu'il est excité, le vérin en position de fermeture de la grille, ledit éiectro-aimant cessant d'tre excité lorsque le moteur du dispositif d'extraction mécanique cesse d'tre alimenté ou lorsque ledit signal de mise à l'atmosphère est généré. Preferably, said actuating means comprises a cylinder now, in the released position, the grid in the open position and an electromagnet now, when energized, the cylinder in the closed position of the grid, said electro -magnet ceasing to be excited when the motor of the mechanical extraction device ceases to be supplied or when said venting signal is generated.

Le dispositif de l'invention permet aussi, dès que la pression régnant dans le circuit d'extraction mécanique descend, quelle qu'en soit la raison, en dessous d'une valeur de consigne pré-affichée, de mettre automatiquement les conduits d'évacuation des fumées et gaz de combustion à t'atmosphère, satisfaisant ainsi exactement aux exigences de la réglementation actuellement en vigueur, sans interrompre le fonctionnement des appareils à gaz. The device of the invention also makes it possible, as soon as the pressure prevailing in the mechanical extraction circuit drops, for whatever reason, below a pre-displayed set value, to automatically put the conduits evacuation of smoke and combustion gases to the atmosphere, thus exactly meeting the requirements of the regulations currently in force, without interrupting the operation of gas appliances.

D'autres caractéristiques et avantages ressortiront de la description qui va suivre d'un mode de réalisation du dispositif de l'invention, description donnée à titre d'exemple uniquement et en regard des dessins annexés sur lesquels :
-Figure 1 est une vue schématique en coupe verticale d'un immeuble d'habitation équipé d'un dispositif conforme à l'invention ;
-Figure 2 est une vue partielle agrandie du dispositif de la figure 1, et ;
-Figure 3 représente le schéma de raccordement électrique des moyens de commande/contrôle du dispositif de l'invention.Other characteristics and advantages will emerge from the description which follows of an embodiment of the device of the invention, description given by way of example only and with reference to the appended drawings in which:
-Figure 1 is a schematic view in vertical section of a residential building equipped with a device according to the invention;
-Figure 2 is an enlarged partial view of the device of Figure 1, and;
-Figure 3 shows the electrical connection diagram of the command / control means of the device of the invention.

Sur la figure 1 on a représenté très schématiquement en coupe verticale un immeuble d'habitation à deux niveaux comportant deux conduits verticaux de ventilation 1 et 2 et plus particulièrement des conduits de type connu dénommé shunt illustré en section agrandie en 3. In FIG. 1 is shown very schematically in vertical section a two-storey apartment building comprising two vertical ventilation ducts 1 and 2 and more particularly ducts of known type called shunt illustrated in enlarged section at 3.

Ce type de conduit comporte plusieurs compartiments, à savoir, I'un (4) affecté aux fumées et gaz de combustion émanant d'appareils à gaz 5 (chaudière ou chauffe-eau par exemple) installés dans les divers logements de l'immeuble, et deux autres (6,7) affectés respectivement à t'aération des cuisines et des espaces sanitaires (salles de bains, WC). This type of duct has several compartments, namely, one (4) assigned to the smoke and combustion gases emanating from gas appliances 5 (boiler or water heater for example) installed in the various dwellings of the building, and two others (6,7) assigned respectively to the ventilation of kitchens and sanitary spaces (bathrooms, WC).

Conformément à l'invention, I'extrémité supérieure des conduits 1, 2 est chapeautée par un caisson 8 divisé en deux compartiments 8a, 8b disposés (figure 2) en regard, l'un (8a), du conduit 4 d'évacuation des fumées et gaz brûlés et, I'autre (8b), des conduits 6,7 de ventilation sur lesquels sont raccordées les sorties d'air d'aération de certaines pièces de l'immeuble.  According to the invention, the upper end of the conduits 1, 2 is capped by a box 8 divided into two compartments 8a, 8b arranged (FIG. 2) opposite, one (8a), of the conduit 4 for discharging smoke and burnt gases and, the other (8b), ventilation ducts 6,7 to which the ventilation air outlets of certain parts of the building are connected.

Chaque compartiment 8a, 8b est raccordé, via une conduite 9 munie d'un registre 10, à t'entrée d'un caisson d'extracteur 1 1 équipe d'un ensemble moto-ventilateur (non représenté) et rejetant à l'atmosphère par un conduit 13 les fumées et gaz aspirés.Each compartment 8a, 8b is connected, via a pipe 9 provided with a register 10, to the inlet of an extractor box 1 1 fitted with a motor-fan assembly (not shown) and rejecting the atmosphere by a conduit 13 the fumes and gases sucked.

Les compartiments 8a affectés aux conduits d'évacuation des fumées et gaz brutes peuvent tre mis à l'atmosphère via une grille d'obturation 13 à lames orientables 14', la grille étant représentée en position d'ouverture en 13' et en position de fermeture en 13". En 14 est schématisé un chapeau protecteur. The compartments 8a assigned to the smoke and raw gas discharge conduits can be vented via a shutter grid 13 with orientable blades 14 ′, the grid being shown in the open position at 13 ′ and in the position of closure in 13 ". In 14 is shown a protective cap.

La grille 13 comprend un châssis portant des lames orientables 14', ainsi qu'un vérin à gaz 15 agencée de façon que la tige pousse en permanence par une tringlerie 16 les lames 14'dans la position d'ouverture, dite position de repos ou de sécurité. The grid 13 comprises a frame carrying orientable blades 14 ′, as well as a gas spring 15 arranged so that the rod pushes permanently by a linkage 16 the blades 14 ′ in the open position, called the rest position or of security.

Dans le mode de réalisation représentée la mise en position de fermeture de la grille 13 est manuelle à I'aide d'un levier 17. In the embodiment shown, putting the grid 13 in the closed position is manual using a lever 17.

Un électro-aimant 18 est connecté, via un relais 19, à un organe de sécurité positive 20 situé à distance (figure 3) et électriquement relié à une source d'alimentation électrique 21, à un pressostat 22 agencé (figure 1) dans le circuit de dépression du caisson de ventilation 11 et à un poste 23 de signalisation, alarme, information, situé à distance par exemple dans un local technique approprié au rez-de-chaussée de l'immeuble. An electromagnet 18 is connected, via a relay 19, to a positive safety device 20 located at a distance (FIG. 3) and electrically connected to a source of electrical power 21, to a pressure switch 22 arranged (FIG. 1) in the vacuum circuit of the ventilation unit 11 and to a signaling, alarm, information station 23, located remotely for example in an appropriate technical room on the ground floor of the building.

Le fonctionnement du dispositif décrit ci-dessus est le suivant. The operation of the device described above is as follows.

Lorsque le système d'extraction mécanique (11) n'est pas en service, les grilles 13 sont en position d'ouverture. When the mechanical extraction system (11) is not in service, the grids 13 are in the open position.

La mise en service implique une intervention manuelle sur les leviers 17, afin d'amener la palette 24 en contact avec la bobine d'électro-aimant 18 préalablement excitée pour maintenir collée ladite palette 24 à l'encontre de la force du vérin 15 qui se trouve alors en position de fermeture de la grille (13"). Commissioning involves manual intervention on the levers 17, in order to bring the pallet 24 into contact with the electromagnet coil 18 previously excited to keep the said pallet 24 stuck against the force of the jack 15 which is then in the closed position of the grid (13 ").

Cette commande manuelle permet d'assurer un contrôle visuel complet du système avant mise en route de l'extracteur.  This manual control ensures complete visual control of the system before starting the extractor.

Au lieu d'une commande manuelle on pourrait bien entendu prévoir un actionnement mécanique des leviers 17 par un moyen commandé à la mise sous tension du moteur de 1'extracteur 11,
Dès que 1'extracteur fonctionne, I'organe de sécurité 20 contrôle, via le pressostat 22, la pression régnant dans le caisson de ventilation.Instead of manual control, it is of course possible to provide mechanical actuation of the levers 17 by a means controlled when the motor of the extractor 11 is energized,
As soon as the extractor operates, the safety member 20 controls, via the pressure switch 22, the pressure prevailing in the ventilation box.

Si la pression tombe en dessous d'ure valeur de consigne pré-affichée et réglable, I'organe 20 génère un signal sur la ligne 25 qui va commander la désexcitation des bobines 18, libérant ainsi les palettes 24. Les vérins 15 poussent alors les lames 14'en position d'ouverture (13'). If the pressure falls below a pre-displayed and adjustable setpoint value, the member 20 generates a signal on the line 25 which will control the de-excitation of the coils 18, thus releasing the pallets 24. The jacks 15 then push the blades 14 'in open position (13').

Ainsi, dès que le moteur de 1'extracteur 11 s'arrte, mme si celui-ci est toujours sous tension, I'électro-aimant 18 n'est plus alimenté et les caissons 8 sont mis automatiquement en position de ventilation naturelle. Thus, as soon as the extractor 11 motor stops, even if the latter is still energized, the electromagnet 18 is no longer supplied and the boxes 8 are automatically put in the natural ventilation position.

Le signal généré par l'organe 20 peut éventuellement également commander la mise hors tension du moteur de l'extracteur. The signal generated by the member 20 can optionally also control the switching off of the extractor motor.

Enfin, l'invention n'est évidemment pas limitée au mode de réalisation représenté et décrit ci-dessus mais en couvre au contraire toutes les variantes, notamment en ce qui concerne la nature des organes de mise à l'atmosphère des caissons 8 et leurs moyens de commande en position de fermeture ainsi qu'en position d'ouverture automatique en cas de tout dysfonctionnement du système extracteur 11.  Finally, the invention is obviously not limited to the embodiment shown and described above but on the contrary covers all the variants thereof, in particular as regards the nature of the members for venting the chambers 8 and their control means in the closed position as well as in the automatic open position in the event of any malfunction of the extractor system 11.
