Definitions
- the invention relates to an air conditioning device, intended for a plurality of premises, distributed along a service corridor, at least one wall of which constitutes partitions for these premises, and comprising a plurality of air conditioning batteries, each assigned to a room comprising a box where, under the impulse of a motor-fan group, air circulates between a return outlet and a blowing outlet, passing through a filter in series, an exchanger connected to a general circuit coolant and a heating coil.
- a first device consists in installing a general air conditioning unit, with refrigeration and heating groups and exchangers equipped with motor-fan groups, filters, to treat the air which is then distributed to the various premises by a network.
- supply air ducts coupled with a network of return ducts to bring the air from the premises to the air conditioning unit.
- This type of device generally requires having been provided for the construction of the building, the ducts are bulky, and the modulation of the air conditioning in each room is difficult without unbalancing the whole.
- Another type of device easier to install in an already constructed building, consists in installing, in each room to be air conditioned, an air conditioning battery comprising a motor-fan group, a filter, an exchanger supplied with coolant, and a battery of heating, for example an electrical resistance, and for the whole building a refrigeration plant from where a heat transfer liquid is refrigerated and distributed by a network of pipes to each battery exchanger.
- the coolant distribution and return pipes are much less bulky than air conditioning ducts, the energy transported per unit of volume being more than 3,000 times higher for water than for air.
- the coolant pipes follow the service corridors, often above a false ceiling and, in line with each room to be refrigerated, there are two taps on the supply pipes and return, which enter the room to service the air conditioning battery.
- the air conditioning battery generally comprises a trunk where, under the impulse of the motor-fan group, the air circulates between a return outlet and a blower outlet, passing in series through the filter, the exchanger suitably connected to the circuit general coolant and heating coil.
- the return and blowing outlets are associated with ducts which open into the room in carefully chosen locations. It is common for the air conditioning battery and / or ducts to be hidden above a false ceiling.
- Each air conditioning battery has thermostatic control members, which act on the flow of coolant, the flow of air in the battery and the heating of the heating coil, or on some of these parameters. It is therefore possible, without unbalancing the entire device, to modulate the air conditioning of each of the premises.
- the invention aims to improve air conditioning devices with individual batteries, by overcoming their objectionable aspects.
- the invention provides an air conditioning device, intended for a plurality of premises distributed along a service corridor of which at least one wall constitutes a partition for the premises, and comprising a plurality of air conditioning batteries, each assigned to a room and comprising a box where, under the impulse of a motor-fan group, air circulates from a return outlet to a blowing outlet, passing through a filter, an exchanger connected to a general circuit of coolant, and a heating coil, characterized in that the return and blowing outlets are located in the same face of the trunk and this is mounted in the service corridor with the face where the outlets are located applied to the partition, where passages are made corresponding respectively to the return and blowing outlets.
- the air conditioning battery box By placing the air conditioning battery box in the service corridor, the annoying source of noise is transferred outside the room, as well as the source of condensation and possible refrigerant leakage. In addition, the maintenance of the air conditioning battery no longer requires entering the room at the risk of disturbing the occupants. Finally, the general coolant circuit is simplified, by shortening, for each battery, the branches from the pipes placed in the service corridor.
- the sides of the trunk generally rectangular in shape, will be fitted with thermal and sound insulation.
- an air conditioning battery arranged in a trunk 4 is mounted on a partition 1 of a service corridor 2, to serve a room 3, such as a hotel room or a office.
- a partition 1 In this partition 1 is made a rectangular opening 1a, near the ceiling and extended parallel to it.
- the trunk 4 being generally parallelepiped, it has on one side two superimposed mouths 10 and 17 which fit into the opening 1a.
- the upper mouth 10 forms the return mouth, and the lower mouth 17 the blowing mouth.
- the horizontal separation between the vents is located at a false ceiling 3n, in which will be practiced, at appropriate locations, air intake vents from room 3 (not shown) while the blowing outlet delivers air conditioning to the room, here directly.
- the return mouth extends, inside the trunk 4 by a sheath 11, limited to its lower part by a horizontal partition 11a which extends from the front face 103 to the rear face 101 of the trunk 4.
- the partition 11a stops before the posterior face 101, to form an opening where a generally flat and horizontal filter 12 is placed.
- a motor-fan group Below the filter 12 is arranged a motor-fan group; in this group, a central motor 13a drives two rotors of centrifugal fans 13, the scrolls of which open into a vertical partition 13b, in the direction of the blowing mouth 17.
- the vertical partition 13b, the rear face 101 of the trunk 4, the filter 12 and a lower face 102 of the box 4 confines a box with which the suction openings of the fans 13 are in communication.
- an exchanger or refrigeration coil 14 In front of the partition 13b is arranged an exchanger or refrigeration coil 14, with inlet pipes 14a and outlet 14b of coolant, respectively connected to supply pipes 21 and return 22, insulated, longitudinally arranged in lane 2 and which, with a refrigeration unit (not shown, of course), refrigerant circuits.
- the refrigeration battery 14 is followed by a heating battery constituted by an electric heating resistor 15.
- a collecting tank 16 for the condensed water vapor is disposed below the exchanger or the cooling coil 14 .
- This tank 16 comprises at the end an outlet 16a, which communicates with a tank 5, fixed outside the trunk 4, on a lateral face 105 of the latter.
- This reservoir has an overflow which opens into a general evacuation pipe 23, parallel to the pipes 21 and 22 of coolant. Of course this pipe 23 is connected, from place to place, to the downspouts for discharging waste water.
- the fans 13 in operation place under vacuum the box formed by the filter 12, the partition 13b, the rear wall 101 and bottom 102, as well as the side walls 104 and 105 of the box. Air is drawn in accordingly through the filter 12 in the sheath 11 and, via the return outlet 10, in the room 3, through the return orifices of the false ceiling 3A. The fans 13 discharge the air thus sucked through the exchanger 14, where it cools and abandons the excess water vapor, then through the resistor 15 where it heats up, before being returned to the room 3 through the air outlet 17.
- the air conditioning battery comprises regulating members, thermostatic control, to modulate the circulation of coolant in the battery 14, the heating of the resistor 15, and, moreover, the speed at which the motor 13a. drives the fans 13.
- the air conditioning battery is classic in principle, and by the organs that constitute it. But, while conventionally we have the different elements in line to separate the return air intake and the supply air, and make the installation inside the room to be conditioned efficient, here we fold the alignment of the elements to attach the return air vents and blowing through the partition 1.
- the trunk 4 was substantially parallelepipedic, with an anterior face 103, a posterior face 101, an upper face 100, a lower face 102, and two lateral faces 104 and 105. All these faces are filled with layers of foam. rigid, about 10 mm thick, forming thermal and sound insulation, with the exception, for the front face 103, of the location of the return 10 and blowing 17 outlets. Thanks to this arrangement, and by l use of fans extended along the axis of rotation of the rotor, the noise level transmitted outside the trunk 4 in the corridor 2 is low, while the partition 1 essentially prevents the transmission of noise inside the local 3.
- the filter 12 is mounted in a drawer in the rear wall 101, with a face 120 on outside the wall 101. Also the assembly of the refrigeration exchanger 14, the resistor 15 and the tank 16 can be extracted from the trunk by a hatch formed in the lower wall 102.
- FIG. 3 represents the arrangement of air conditioning batteries 40, 41, 42, 43, assigned respectively to premises 30, 31, 32, 33, distributed on either side of a service corridor 2, limited by partitions 1 and 1 ′ which separate it respectively from the premises with even and odd references.
- air conditioning batteries which are connected to the supply lines 21 and return 22 of the coolant, by short branches.
- auxiliary tanks 50, 51, 52, 53 for collecting condensate from the respective batteries 40, 41, 42, 43. These tanks 50, 51, 52, 53 are connected as short as possible to the drain pipe 23 condensates.
- the invention is not limited to the examples described, but embraces all of the variant embodiments thereof, within the framework defined by the claims.
- the location of the fan in the air circulation is arbitrary.
- the heating coil has been described in the form of an electrical resistance. But it goes without saying that this heating coil can be an exchanger supplied by a hot heat-transfer liquid, like a central heating radiator. Also when heating is provided by passing a heat transfer liquid through an exchanger, it is possible to confuse the cold battery and the hot battery into a single exchanger, which will be supplied, depending on the circumstances, with coolant or hot coolant.
- the invention is also applicable to buildings where the premises are not regularly distributed on either side of a service corridor. It suffices that this corridor serves a plurality of premises to be air conditioned.

Abstract
Description
L'invention se rapporte à un dispositif de climatisation, destiné à une pluralité de locaux, répartis le long d'un couloir de desserte dont une paroi au moins constitue cloisons pour ces locaux, et comportant une pluralité de batteries de climatisation, chacune affectée à un local et comprenant un coffre où, sous l'impulsion d'un groupe moteur-ventilateur, de l'air circule entre une bouche de reprise et une bouche de soufflage, en traversant en série un filtre, un échangeur raccordé à un circuit général de liquide réfrigérant et une batterie de chauffage.The invention relates to an air conditioning device, intended for a plurality of premises, distributed along a service corridor, at least one wall of which constitutes partitions for these premises, and comprising a plurality of air conditioning batteries, each assigned to a room comprising a box where, under the impulse of a motor-fan group, air circulates between a return outlet and a blowing outlet, passing through a filter in series, an exchanger connected to a general circuit coolant and a heating coil.
Pour climatiser les locaux d'un immeuble qui comporte un grand nombre de locaux répartis le long de couloirs de desserte, tel qu'un hôtel ou un immeuble de bureaux, on a recours actuellement à deux types de dispositif. Un premier dispositif consiste à installer une centrale générale de climatisation, avec des groupes de réfrigération et des groupes de chauffage et des échangeurs équipés de groupes moteurs-ventilateurs, de filtres, pour traiter l'air qui est ensuite distribué aux différents locaux par un réseau de gaines de soufflage, doublé d'un réseau de gaines de reprises pour ramener l'air des locaux à la centrale de climatisation. Ce type de dispositif demande généralement d'avoir été prévu à la construction de l'immeuble, les gaines sont encombrantes, et la modulation de la climatisation dans chaque local est difficile sans déséquilibrer l'ensemble.To cool the premises of a building which has a large number of rooms distributed along service corridors, such as a hotel or an office building, two types of device are currently used. A first device consists in installing a general air conditioning unit, with refrigeration and heating groups and exchangers equipped with motor-fan groups, filters, to treat the air which is then distributed to the various premises by a network. supply air ducts, coupled with a network of return ducts to bring the air from the premises to the air conditioning unit. This type of device generally requires having been provided for the construction of the building, the ducts are bulky, and the modulation of the air conditioning in each room is difficult without unbalancing the whole.
Un autre type de dispositif, plus facile à implanter dans un immeuble déjà construit, consiste à installer, dans chaque local à climatiser une batterie de climatisation comprenant un groupe moteur-ventilateur, un filtre, un échangeur alimenté en liquide réfrigérant, et une batterie de chauffage, par exemple une résistance électrique, et pour l'ensemble de l'immeuble une centrale de réfrigération d'où un liquide caloporteur est réfrigéré et distribué par un réseau de canalisations à chaque échangeur de batterie. Les canalisations de distribution et de retour de liquide réfrigérant sont beaucoup moins encombrantes que les gaines d'air de climatisation, l'énergie transportée par unité de volume étant plus de 3 000 fois plus élevée pour l'eau que pour l'air.Another type of device, easier to install in an already constructed building, consists in installing, in each room to be air conditioned, an air conditioning battery comprising a motor-fan group, a filter, an exchanger supplied with coolant, and a battery of heating, for example an electrical resistance, and for the whole building a refrigeration plant from where a heat transfer liquid is refrigerated and distributed by a network of pipes to each battery exchanger. The coolant distribution and return pipes are much less bulky than air conditioning ducts, the energy transported per unit of volume being more than 3,000 times higher for water than for air.
En général, pour ce type de dispositif, les canalisations de liquide réfrigérant suivent les couloirs de desserte, fréquemment au-dessus d'un faux plafond et, au droit de chaque local à réfrigérer, on dispose deux piquages sur les canalisations d'amenée et de retour, qui pénètrent dans le local pour desservir la batterie de climatisation.In general, for this type of device, the coolant pipes follow the service corridors, often above a false ceiling and, in line with each room to be refrigerated, there are two taps on the supply pipes and return, which enter the room to service the air conditioning battery.
La batterie de climatisation comporte en général un coffre où, sous l'impulsion du groupe moteur-ventilateur, l'air circule entre une bouche de reprise et une bouche de soufflage, en traversant en série le filtre, l'échangeur convenablement raccordé au circuit général de liquide réfrigérant et la batterie de chauffage. Aux bouches de reprise et de soufflage sont associées des gaines qui débouchent dans le local en des emplacements judicieusement choisis. Il est fréquent que la batterie de climatisation et/ou les gaines soient dissimulées au-dessus d'un faux plafond. Chaque batterie de climatisation comporte des organes d'asservissement thermostatiques, qui agissent sur le débit de liquide réfrigérant, le débit d'air dans la batterie et le chauffage de la batterie de chauffage, ou sur certains de ces paramètres. Il est donc possible, sans déséquilibrer l'ensemble du dispositif, de moduler la climatisation de chacun des locaux.The air conditioning battery generally comprises a trunk where, under the impulse of the motor-fan group, the air circulates between a return outlet and a blower outlet, passing in series through the filter, the exchanger suitably connected to the circuit general coolant and heating coil. The return and blowing outlets are associated with ducts which open into the room in carefully chosen locations. It is common for the air conditioning battery and / or ducts to be hidden above a false ceiling. Each air conditioning battery has thermostatic control members, which act on the flow of coolant, the flow of air in the battery and the heating of the heating coil, or on some of these parameters. It is therefore possible, without unbalancing the entire device, to modulate the air conditioning of each of the premises.
Toutefois ce type de dispositif présente certains aspects critiquables. Le plus souvent critiqué est le bruit dû au groupe moteur-ventilateur, particulèrement sensible si le local est par ailleurs calme (chambre d'hôtel, bureau particulier). De plus l'entretien des batteries de climatisation exige que le personnel d'entretien pénètre dans les locaux climatisés ; les dérivations des canalisations de circuits réfrigérants augmentent la longueur de ces canalisations et par là même les risques de fuites ou de condensations ; en outre ces fuites ou condensations sont plus nuisibles dans les locaux à climatiser que dans les couloirs de desserte.However, this type of device has certain criticizable aspects. Most often criticized is the noise due to the motor-fan group, which is particularly sensitive if the room is otherwise quiet (hotel room, private office). In addition, the maintenance of air conditioning batteries requires that maintenance personnel enter the air-conditioned premises; the derivations of refrigerant pipes increase the length of these pipes and thereby the risk of leaks or condensation; furthermore, these leaks or condensations are more harmful in the rooms to be air conditioned than in the service corridors.
L'invention vise à perfectionner les dispositifs de climatisation à batteries individuelles, en palliant leurs aspects critiquables.The invention aims to improve air conditioning devices with individual batteries, by overcoming their objectionable aspects.
A cet effet, l'invention propose un dispositif de climatisation, destiné à une pluralité de locaux répartis le long d'un couloir de desserte dont une paroi au moins constitue cloison pour les locaux, et comportant une pluralité de batteries de climatisation, chacune affectée à un local et comprenant un coffre où, sous l'impulsion d'un groupe moteur-ventilateur, de l'air circule d'une bouche de reprise à une bouche de soufflage, en traversant en série un filtre, un échangeur raccordé à un circuit général de liquide réfrigérant, et une batterie de chauffage, caractérisé en ce que les bouches de reprise et de soufflage sont situées dans une même face du coffre et celui-ci est monté dans le couloir de desserte avec la face où sont situées les bouches appliquées à la cloison, où sont pratiqués des passages correspondant respectivement aux bouches de reprise et de soufflage.To this end, the invention provides an air conditioning device, intended for a plurality of premises distributed along a service corridor of which at least one wall constitutes a partition for the premises, and comprising a plurality of air conditioning batteries, each assigned to a room and comprising a box where, under the impulse of a motor-fan group, air circulates from a return outlet to a blowing outlet, passing through a filter, an exchanger connected to a general circuit of coolant, and a heating coil, characterized in that the return and blowing outlets are located in the same face of the trunk and this is mounted in the service corridor with the face where the outlets are located applied to the partition, where passages are made corresponding respectively to the return and blowing outlets.
En disposant le coffre de la batterie de climatisation dans le couloir de desserte, on reporte à l'extérieur du local la source de bruit gênante, ainsi que la source de condensations et fuite de réfrigérant éventuelle. En outre l'entretien de la batterie de climatisation n'impose plus de pénétrer dans le local au risque de déranger les occupants. Enfin le circuit général de liquide réfrigérant est simplifié, par raccourcissement, pour chaque batterie, des dérivations à partir des canalisations placées dans le couloir de desserte.By placing the air conditioning battery box in the service corridor, the annoying source of noise is transferred outside the room, as well as the source of condensation and possible refrigerant leakage. In addition, the maintenance of the air conditioning battery no longer requires entering the room at the risk of disturbing the occupants. Finally, the general coolant circuit is simplified, by shortening, for each battery, the branches from the pipes placed in the service corridor.
Pour améliorer l'insonorisation et le rendement des batteries, on garnira les faces du coffre, à forme générale parallélépipédique, d'un isolant thermique et phonique.To improve the soundproofing and the efficiency of the batteries, the sides of the trunk, generally rectangular in shape, will be fitted with thermal and sound insulation.
D'autres caractéristiques et avantages de l'invention ressortiront d'ailleurs de la description qui va suivre à titre d'exemple, en référence aux dessins annexés dans lesquels :

- Figure 3 is a plan view, from below, of part of a device according to the invention.
Selon la forme de réalisation choisie et représentée figure 1, une batterie de climatisation disposée dans un coffre 4 est montée sur une cloison 1 d'un couloir de desserte 2, pour desservir un local 3, tel qu'une chambre d'hôtel ou un bureau. Dans cette cloison 1 est pratiquée une ouverture rectangulaire la, à proximité du plafond et étendue parallèlement à celui-ci. Le coffre 4 étant généralement parallélépipédique, il présente sur une face deux bouches superposées 10 et 17 qui s'encastrent dans l'ouverture 1a. La bouche supérieure 10 forme bouche de reprise, et la bouche inférieure 17 bouche de soufflage. La séparation, horizontale, entre les bouches se situe au niveau d'un faux plafond 3n, dans lequel seront pratiquées, à des emplacements appropriés, des ouïes de reprise de l'air du local 3 (non représentées) tandis que la bouche de soufflage délivre au local de l'air climatisé, ici directement.According to the embodiment chosen and shown in FIG. 1, an air conditioning battery arranged in a trunk 4 is mounted on a
Pour la description de la batterie de climatisation, on se référera également à la figure 2, plus détaillée.For the description of the air conditioning battery, reference will also be made to FIG. 2, which is more detailed.
La bouche de reprise se prolonge, à l'intérieur du coffre 4 par une gaine 11, limitée à sa partie inférieure par une cloison horizontale 11a qui s'étend de la face antérieure 103 à la face postérieure 101 du coffre 4. La cloison 11a s'arrête avant la face postérieure 101, pour former une ouverture où se place un filtre 12 généralement plan et horizontal.The return mouth extends, inside the trunk 4 by a
En dessous du filtre 12 est disposé un groupe moteur-ventilateur ; dans ce groupe un moteur central 13a entraîne deux rotors de ventilateurs centrifuges 13 dont les volutes débouchent dans une cloison verticale 13b, en direction de la bouche de soufflage 17. La cloison verticale 13b, la face postérieure 101 du coffre 4, le filtre 12 et une face inférieure 102 du coffre 4 confinent un caisson avec lequel les ouïes d'aspiration des ventilateurs 13 sont en communication.Below the
En avant de la cloison 13b est disposé un échangeur ou batterie de réfrigération 14, avec des tubulures d'arrivée 14a et de départ 14b de liquide réfrigérant, respectivement reliées à des canalisations d'amenée 21 et de retour 22, calorifugées, disposées longitudinalement dans le couloir 2 et qui constituent, avec une centrale de réfrigération (non représentée, bien entendu), circuits de liquide réfrigérant.In front of the
La batterie de réfrigération 14 est suivie d'une batterie de chauffage constituée par une résistance chauffante électrique 15.The
En dessous de l'échangeur ou de la batterie réfrigérante 14 est disposé un bac de recueil 16 pour la vapeur d'eau condensée. Ce bac 16 comporte en bout une évacuation 16a, qui communique avec un réservoir 5, fixé à l'extérieur du coffre 4, sur une face latérale 105 de celui-ci. Ce réservoir possède un trop plein qui débouche dans une canalisation générale d'évacuation 23, parallèle aux canalisations 21 et 22 de liquide réfrigérant. Bien entendu cette canalisation 23 est reliée, de place en place, aux descentes d'évacuation des eaux usées.Below the exchanger or the
Au-delà de la résistance 15 s'étend la bouche de soufflage 17.Beyond the
On aura compris que les ventilateurs 13 en fonctionnement mettent en dépression le caisson constitué par le filtre 12, la cloison 13b, les parois postérieure 101 et inférieure 102, ainsi que les parois latérales 104 et 105 du caisson. L'air est aspiré en conséquence à travers le filtre 12 dans la gaine 11 et, par la bouche de reprise 10, dans le local 3, par les orifices de reprises du faux plafond 3A. Les ventilateurs 13 refoulent l'air ainsi aspiré à travers l'échangeur 14, où il se refroidit et abandonne la vapeur d'eau en excès, puis à travers la résistance 15 où il se réchauffe, avant d'être renvoyé dans le local 3 par la bouche de soufflage 17.It will be understood that the
Il va de soi que la batterie de climatisation comporte des organes de réglages, à commande thermostatique, pour moduler la circulation de liquide réfrigérant dans la batterie 14, le chauffage de la résistance 15, et, en outre la vitesse à laquelle le moteur 13a. entraine les ventilateurs 13.It goes without saying that the air conditioning battery comprises regulating members, thermostatic control, to modulate the circulation of coolant in the
Bien entendu, la batterie de climatisation est classique dans son principe, et par les organes qui la constituent. Mais, alors que classiquement on dispose les différents éléments en ligne pour séparer bouche de reprise et bouche de soufflage, et rendre efficace l'implantation à l'intérieur du local à climatiser, ici on replie l'alignement des éléments pour accoler bouches de reprise et de soufflage à la traversée de la cloison 1.Of course, the air conditioning battery is classic in principle, and by the organs that constitute it. But, while conventionally we have the different elements in line to separate the return air intake and the supply air, and make the installation inside the room to be conditioned efficient, here we fold the alignment of the elements to attach the return air vents and blowing through the
On a déjà mentionné que le coffre 4 était sensiblement parallélépipédique, avec une face antérieure 103, une face postérieure 101, une face supérieure 100, une face inférieure 102, et deux faces latérales 104 et 105. Toutes ces faces sont garnies de couches de mousse rigide, d'environ 10 mm d'épaisseur, formant isolant thermique et phonique, à l'exception, pour la face antérieure 103, de l'emplacement des bouches de reprise 10 et de soufflage 17. Grâce à cette disposition, et par l'utilisation de ventilateurs étendus suivant l'axe de rotation du rotor, le niveau de bruit transmis en dehors du coffre 4 dans le couloir 2 est bas, tandis que la cloison 1 empêche pour l'essentiel la transmission du bruit à l'intérieur du local 3.We have already mentioned that the trunk 4 was substantially parallelepipedic, with an
Pour faciliter l'entretien le filtre 12 est monté en tiroir dans la paroi postérieure 101, avec une face 120 sur l'extérieur de la paroi 101. Egalement l'ensemble de l'échangeur de réfrigération 14, de la résistance 15 et du bac 16 peut être extrait du coffre par une trappe formée dans la paroi inférieure 102.To facilitate maintenance, the
La figure 3 représente la disposition de batteries de climatisation 40, 41, 42, 43, affectées respectivement à des locaux 30, 31, 32, 33, répartis de part et d'autre d'un couloir de desserte 2, limité par des cloisons 1 et 1' qui le séparent respectivement des locaux à références paires et impaires. On appréciera la disposition compacte des batteries de climatisation, qui se raccordent aux canalisations d'amenée 21 et de retour 22 du liquide réfrigérant, par des dérivations courtes. On voit également les réservoirs auxiliaires 50, 51, 52, 53 pour le recueil des condensats des batteries respectives 40, 41, 42, 43. Ces réservoirs 50, 51, 52, 53 sont reliés au plus court à la canalisation 23 d'évacuation des condensats.FIG. 3 represents the arrangement of
Il est clair que cette disposition, outre les avantages de réduction de bruit dans les locaux desservis, facilite l'entretien, sans dérangement des occupants des locaux. Les inconvénients liés aux dérivations classiques de liquide réfrigérant qui pénètrent dans les locaux, généralement dissimulés au-dessus de faux plafonds, à savoir les condensations sur les canalisations, et les risques de fuite, disparaissent pour les locaux desservis, et sont nettement diminués dans les couloirs de desserte.It is clear that this arrangement, in addition to the advantages of noise reduction in the premises served, facilitates maintenance, without disturbing the occupants of the premises. The drawbacks associated with conventional refrigerant diversions entering the premises, generally hidden above false ceilings, namely condensation on the pipes, and the risk of leaks, disappear for the premises served, and are clearly reduced in service corridors.
Bien entendu l'invention n'est pas limitée aux exemples décrits, mais en embrasse toutes les variantes d'exécution, dans le cadre défini par les revendications. Notamment, dans les batteries de climatisation, l'emplacement du ventilateur dans la circulation d'air est quelconque.Of course, the invention is not limited to the examples described, but embraces all of the variant embodiments thereof, within the framework defined by the claims. In particular, in air conditioning batteries, the location of the fan in the air circulation is arbitrary.
La batterie de chauffage a été décrite sous forme d'une résistance électrique. Mais il va de soi que cette batterie de chauffage peut être un échangeur alimenté par un liquide caloporteur chaud, à l'instar d'un radiateur de chauffage central. De plus lorsque le chauffage est assuré par passage dans un échangeur d'un liquide caloporteur, il est possible de confondre batterie froide et batterie chaude en un échangeur unique, qui sera alimenté, selon les circonstances, en liquide réfrigérant ou en liquide caloporteur chaud.The heating coil has been described in the form of an electrical resistance. But it goes without saying that this heating coil can be an exchanger supplied by a hot heat-transfer liquid, like a central heating radiator. Also when heating is provided by passing a heat transfer liquid through an exchanger, it is possible to confuse the cold battery and the hot battery into a single exchanger, which will be supplied, depending on the circumstances, with coolant or hot coolant.
D'un autre point de vue, l'invention est également applicable à des bâtiments où les locaux ne sont pas répartis régulièrement de part et d'autre d'un couloir de desserte. Il suffit que ce couloir desserve une pluralité de locaux à climatiser.From another point of view, the invention is also applicable to buildings where the premises are not regularly distributed on either side of a service corridor. It suffices that this corridor serves a plurality of premises to be air conditioned.
