Description

Domaine de l'inventionField of the invention

L'invention concerne les convecteurs thermiques destinés à climatiser des locaux et, en particulier, des locaux domestiques, tels que ceux utilisés dans les appartements privés.The invention relates to convectors intended for air conditioning of premises and, in particular, domestic premises, such as those used in private apartments.

Art antérieur et problème poséPrior art and problem posed

On sait chauffer des locaux au moyen de convecteurs à tirage naturel. Ces convecteurs sont souvent des appareils muraux comprenant au moins un élément chauffant placé à l'intérieur d'une chambre de convexion à travers laquelle l'air chauffé est envoyé vers le haut de l'appareil.We know how to heat premises using convectors with natural draft. These convectors are often wall fixtures with at least one heating element placed inside a convection through which heated air is sent towards the top of the device.

La figure 1 représente un type de convecteurs connus par le brevet français FR-A-2 726 636. Un tel type de convecteur 1 est fixé sur un mur 3. Il possède une chambre de convexion 10 comprenant un compartiment avant 11 et un compartiment arrière 12. L'entrée de l'air 21 se trouve à la base 20 du convecteur 1 sous la forme d'une grille 22. A l'intérieur du compartiment arrière 12, de préférence en bas, se trouve au moins un élément chauffant 2. Comme l'indique les flèches, l'air ambiant dans le local pénètre donc par l'entrée d'air 20, monte, une fois chauffé, dans le compartiment arrière 12 et arrive dans la partie supérieure 14 de la chambre de convexion 10. La paroi supérieure 42 renvoie l'air chauffé dans le compartiment avant 11. Une sortie d'air 31 est prévue dans une paroi frontale 30, plutôt dans sa partie inférieure. Des ailettes 33 inclinées vers le bas peuvent équiper cette sortie d'air 31 pour envoyer la chaleur vers le bas du local. On note que cette sortie d'air 31 est légèrement plus haute que l'entrée d'air 21.Figure 1 shows a type of convectors known by the French patent FR-A-2 726 636. Such a type of convector 1 is fixed on a wall 3. It has a convection chamber 10 comprising a front compartment 11 and a compartment rear 12. Air inlet 21 is located at base 20 convector 1 in the form of a grid 22. A inside the rear compartment 12, preferably at the bottom there is at least one heating element 2. As indicated by the arrows, the ambient air in the room therefore enters through air inlet 20, goes up, a once heated, in the rear compartment 12 and arrives in the upper part 14 of the convection chamber 10. The upper wall 42 returns the heated air to the front compartment 11. An air outlet 31 is provided in a front wall 30, rather in its lower part. Fins 33 inclined towards the low can equip this air outlet 31 to send the heat down the room. We note that this air outlet 31 is slightly higher than the inlet air 21.

On comprend ainsi que ce convecteur fonctionne par tirage naturel et permet de chauffer un local dans lequel il est installé.It is thus understood that this convector works by natural draft and allows to heat a room in which it is installed.

D'autre part, dans les pays chauds, ou en saison chaude, on utilise des appareils de climatisation pour rafraíchir l'air ambiant. Mis à part le fait que la source froide, qui peut être une pompe à chaleur, une pompe au Fréon telle que celle utilisée dans les réfrigérateurs, ou un autre dispositif, l'utilisation d'un ventilateur est nécessaire pour obtenir la circulation de l'air froid vers le local. Les ventilateurs actuellement connus sont légèrement bruyants, ce qui est un handicap majeur dans le cadre de l'utilisation de tels climatiseurs, ou "ventilo-convecteurs", dans des installations domestiques, ou dans des bureaux.On the other hand, in hot countries, or in hot season, we use air conditioning to cool the ambient air. Except the fact that the cold source, which can be a heat, a Freon pump like the one used in refrigerators, or other device, the use of a fan is necessary to get cold air circulation to the room. The fans currently known are slightly noisy, which is a major handicap in the context the use of such air conditioners, or "fan coil units", in installations domestic, or in offices.

Le but de l'invention est de proposer un appareil permettant de pouvoir produire de l'air chaud, ou de l'air froid, dans n'importe quel local, sans apporter de nuisances acoustiques.The object of the invention is to propose a device enabling hot air to be produced, or cold air, in any room, without bring noise pollution.

Résumé de l'inventionSummary of the invention

A cet effet, l'objet principal de l'invention est un convecteur de climatisation thermique comprenant :

  • un carter qui délimite une chambre de convexion, comprenant une première entrée d'air inférieure, ainsi qu'une paroi frontale sensiblement verticale qui comporte une sortie d'air et qui présente une extrémité inférieure, la sortie d'air étant disposée à un niveau supérieur à la première entrée d'air et comprenant des parois arrière, latérales, et supérieure, la chambre de convexion étant divisée en un compartiment avant et un compartiment arrière par une cloison sensiblement verticale qui est raccordée jointivement à l'extrémité inférieure de la paroi frontale et aux parois latérales du carter, le compartiment arrière communiquant avec la première entrée d'air, le compartiment avant communiquant, d'une part, avec le compartiment arrière par le dessus de la cloison et, d'autre part, avec la sortie d'air, laquelle est disposée au voisinage de l'extrémité inférieure de la paroi frontale ; et
  • une source chaude disposée dans le compartiment arrière de la chambre de convexion.
To this end, the main object of the invention is a thermal air conditioning convector comprising:
  • a casing which delimits a convection chamber, comprising a first lower air inlet, as well as a substantially vertical front wall which has an air outlet and which has a lower end, the air outlet being arranged at a level higher than the first air inlet and comprising rear, side and upper walls, the convection chamber being divided into a front compartment and a rear compartment by a substantially vertical partition which is joined contiguously to the lower end of the wall front and side walls of the housing, the rear compartment communicating with the first air inlet, the front compartment communicating, on the one hand, with the rear compartment through the top of the partition and, on the other hand, with the outlet air, which is arranged in the vicinity of the lower end of the front wall; and
  • a hot spring located in the rear compartment of the convection chamber.

Selon l'invention, le convecteur comprend :

  • une source froide placée dans une deuxième entrée d'air placée dans la partie supérieure de la paroi arrière et présentant une légère perte de charges, pour faire passer, en le refroidissant, de l'air placé derrière le convecteur vers l'intérieur de la partie supérieure de la chambre de convexion ; et
  • des moyens de commande des sources chaude et froide pour faire fonctionner, soit l'une, soit l'autre de ces deux sources, l'air circulant ainsi de haut en bas dans le compartiment avant de la chambre de combustion, exclusivement par effet de thermosiphon, quelque soit le mode de fonctionnement choisi.
According to the invention, the convector comprises:
  • a cold source placed in a second air inlet placed in the upper part of the rear wall and having a slight pressure drop, to pass, by cooling it, air placed behind the convector towards the interior of the upper part of the convection chamber; and
  • means for controlling the hot and cold sources to operate either one or the other of these two sources, the air thus circulating from top to bottom in the front compartment of the combustion chamber, exclusively by the effect of thermosiphon, whatever the operating mode chosen.

Dans la réalisation principale du convecteur selon l'invention, la paroi frontale du carter est formée en un matériau bon conducteur de la chaleur, tandis que la paroi arrière du carter est une paroi thermiquement isolante.In the main realization of the convector according to the invention, the front wall of the housing is formed of a material which is a good conductor of the heat, while the rear wall of the housing is a thermally insulating wall.

Dans ce cas, de préférence, la paroi arrière du carter comporte une plaque métallique séparée du compartiment arrière de la chambre de convexion par une couche thermiquement isolante.In this case, preferably, the wall rear of the housing has a metal plate separated from the rear compartment of the convection by a thermally insulating layer.

Il est également prévu que la paroi supérieure du carter soit thermiquement isolante et comporte une plaque métallique qui est séparée de la chambre de convexion par une couche thermiquement isolante.It is also expected that the wall upper part of the casing is thermally insulating and has a metal plate which is separate from the convection chamber by a thermal layer insulating.

De préférence, dans le convecteur, selon l'invention, les parois latérales du carter présentent chacune une portion qui délimite latéralement le compartiment arrière de la chambre de convexion, au moins cette portion de chaque paroi latérale étant thermiquement isolante et comportant une plaque métallique qui est séparée de la chambre de convexion par une couche thermiquement isolante, au moins dans la portion de la paroi latérale qui délimite latéralement le compartiment arrière de la chambre de convexion.Preferably, in the convector, according to the invention, the side walls of the housing have each a portion which laterally delimits the rear compartment of the convection chamber, at minus that portion of each side wall being thermally insulating and comprising a plate metallic which is separated from the convection chamber by a thermally insulating layer, at least in the portion of the side wall which delimits laterally the rear compartment of the convection chamber.

Dans sa réalisation préférentielle, la sortie d'air du convecteur, selon l'invention, comporte des ailettes inclinées vers le bas, de l'arrière vers l'avant, pour diriger en biais vers le bas l'air qui sort de la chambre de convexion.In its preferred embodiment, the air outlet of the convector, according to the invention, comprises fins inclined downwards, from rear to the front, to direct the air which is slanting downwards comes out of the convection chamber.

Dans une réalisation préférentielle du convecteur selon l'invention, la source chaude est une source électrique. In a preferred embodiment of the convector according to the invention, the hot source is a electrical source.

La source froide est, de préférence, réalisée par une batterie d'échange à ailettes et alimentée par une source d'eau glacée.The cold source is preferably produced by a finned exchange battery and powered by a source of chilled water.

Les sources chaude et froide peuvent être alimentées par une unique pompe à chaleur réversible placée à un autre endroit que celui où est placé le convecteur.Hot and cold sources can be powered by a single reversible heat pump placed elsewhere than where the convector.

De préférence, on utilise des moyens d'obturation dans le compartiment avant de la chambre de convexion pour éviter que l'air ne remonte dans la partie supérieure de cette dernière.Preferably, means are used shutter in the front compartment of the room convection to prevent air from going up in the upper part of the latter.

Il est également utile d'utiliser un profil en couvercle placé au-dessus d'une cloison séparant le compartiment avant et le compartiment arrière, de forme recourbée et étant fixé sur une paroi arrière du convecteur pour obliger l'air chaud en provenance du compartiment arrière à se diriger vers le compartiment avant.It is also useful to use a profile in cover placed above a partition separating the front compartment and rear compartment, shaped curved and being fixed on a rear wall of the convector to force hot air from the rear compartment to head towards the compartment before.

  • Figure 2, a convector according to the invention.

Description détaillée d'une réalisation de l'inventionDetailed description of a realization of the invention

En référence à la figure 2, on retrouve tous les éléments du convecteur selon l'art antérieur sur cette figure. Ainsi, la chambre de convexion 50 est toujours partagée en un compartiment avant 51 et un compartiment arrière 52 par une cloison sensiblement verticale 53 qui est isolante. Une première entrée 61 de l'air ambiant est placée à la base 60 du convecteur. Elle est équipée, de préférence, d'une grille 62. La source chaude 55 peut être une résistance électrique située à ce niveau de la grille 62, ou être un élément chauffant quelconque placé un peu plus haut, comme l'est l'élément chauffant 2 de la figure 1. La partie supérieure du convecteur est équipée d'une plaque métallique 64 placée sur la face extérieure du convecteur et qui est séparée de la chambre de convexion 50 par une couche thermiquement isolante 65. Ceci constitue la paroi supérieure 93 du convecteur.Referring to Figure 2, we find all elements of the convector according to the prior art in this figure. Thus, the convection chamber 50 is always divided into a compartment before 51 and a rear compartment 52 by a partition substantially vertical 53 which is insulating. A first entry 61 ambient air is placed at the base 60 of the convector. It is preferably equipped with a grid 62. The hot spring 55 can be an electrical resistance located at this level of grid 62, or be an element any heater placed a little higher, like is the heating element 2 of figure 1. The part top of the convector is fitted with a plate metal 64 placed on the outside of the convector and which is separate from the convection 50 by a thermally insulating layer 65. This constitutes the upper wall 93 of the convector.

La paroi frontale 70 est formée d'un matériau bon conducteur de la chaleur pour qu'une partie de la chaleur apportée par l'air chaud provenant du compartiment arrière 52 chauffe cette paroi frontale 70 pour que cette dernière rayonne dans le local.The front wall 70 is formed of a good heat conductive material so that a part of the heat provided by the hot air from rear compartment 52 heats this front wall 70 so that the latter shines in the room.

Une paroi arrière 90 est prévue et est composée d'une plaque métallique 91 séparée du compartiment arrière 52 de la chambre de convexion 50 par une couche thermiquement isolante 92. Les parois latérales, non représentées, sont construites de la même façon. On peut se référer à la figure 3 du brevet français FR-A-2 726 636 déjà évoqué dans cette demande. A l'avant du convecteur est placée une paroi frontale 70 équipée dans sa partie inférieure d'une sortie d'air 71, éventuellement munie d'ailettes 73 inclinées vers le bas.A rear wall 90 is provided and is composed of a metal plate 91 separated from the rear compartment 52 of the convection chamber 50 by a thermally insulating layer 92. The walls side, not shown, are constructed from the same way. We can refer to Figure 3 of the patent French FR-A-2 726 636 already mentioned in this request. At the front of the convector is placed a front wall 70 fitted in its lower part with an air outlet 71, possibly fitted with fins 73 inclined towards the bottom.

La source froide, selon l'invention, est placée dans une deuxième entrée d'air 100 du convecteur située dans la partie supérieure de la paroi arrière 90 du convecteur. Elle débouche dans la partie supérieure 54 de la chambre de convexion 50.The cold source according to the invention is placed in a second air inlet 100 of the convector located in the upper part of the rear wall 90 of the convector. It opens into the upper part 54 of the convection chamber 50.

On prévoit un profil en couvercle 104 constituant un auvent, placé à l'intérieur de la chambre de convexion 50, juste au-dessus de la cloison isolante 53, fixé sur la couche thermiquement isolante 92. Avec sa forme incurvée vers le bas, il permet ainsi à l'air chaud sortant du compartiment arrière 52 de la chambre de convexion 50 d'être renvoyé directement dans le compartiment avant 51 de celle-ci, en direction de la sortie de l'air 71.A cover profile 104 is provided constituting an awning, placed inside the convection chamber 50, just above the partition insulating 53, fixed on the thermally insulating layer 92. With its curved downward shape, it thus allows with hot air exiting the rear compartment 52 of the convection chamber 50 to be returned directly to the front compartment 51 thereof, in the direction of the air outlet 71.

De plus, on prévoit dans le compartiment avant 51 de la chambre de convexion 50 un moyen d'obturation 105 pour éviter à l'air chaud de remonter dans la partie supérieure 54 de la chambre de convexion 50. Ces moyens d'obturation peuvent être constitués d'un clapet obturateur.In addition, there is provision in the compartment before 51 of the convection chamber 50 a means shutter 105 to prevent hot air from rising in the upper part 54 of the convection chamber 50. These sealing means may be made up a shutter valve.

La source froide peut être réalisée sous la forme d'une batterie classique à ailettes alimentée par un circuit d'eau glacée. Une caractéristique de cette source froide est qu'elle présente une légère perte de charges pour l'air venant de l'extérieur, c'est-à-dire de derrière le convecteur et se dirigeant vers la partie supérieure 54 de la chambre de convexion 50. Ceci permet de faciliter l'organisation de la sortie de l'air, même chaud, par la sortie d'air 71 qui se trouve plutôt vers le bas de la chambre de convexion 50, au lieu de remonter et de sortir par la source froide 101. The cold source can be produced under the shape of a classic finned battery powered by a chilled water circuit. A feature of this cold source is that it has a slight loss of charges for air coming from outside, i.e. from behind the convector and heading towards the upper part 54 of the convection chamber 50. This facilitates the organization of the exit from air, even hot, through the air outlet 71 which is located rather towards the bottom of the convection chamber 50, at the instead of going up and out through the cold source 101.

La source chaude 55 peut être alimentée en énergie électrique par le réseau de distribution d'électricité. La source d'eau froide 101 peut être alimentée en eau glacée par une pompe à chaleur placée dans un endroit par forcément voisin de l'endroit où est placé le convecteur. On peut également envisager qu'une unique pompe à chaleur 110 puisse fournir l'eau froide pour la source froide 101 et de l'eau chaude pour la source chaude 55. Des moyens de commande 120 sont prévus pour faire fonctionner, soit l'une, ou l'autre de ces sources 110 et 111, en fonction de la température régnant dans le local où est installé le convecteur.The hot source 55 can be supplied with electrical energy through the distribution network of electricity. The cold water source 101 can be supplied with chilled water by a heat pump placed in a place by necessarily close to where the convector is placed. We can also consider that a single heat pump 110 can supply water cold for cold source 101 and hot water for the hot spring 55. Control means 120 are provided to operate either one or the other of these sources 110 and 111, depending on the temperature prevailing in the room where the convector.

On comprend ainsi que l'air ambiant pénétrant par la source froide 101 est refroidi. En conséquence, lorsqu'il se trouve dans la partie supérieure 54 de la chambre de convexion 50, il a tendance à descendre et se dirige donc vers la sortie d'air 71. Lorsque la source chaude est opérationnelle, l'air chaud monte dans le compartiment arrière 52 et redescend par le compartiment avant 51 de la chambre de convexion.We understand that the ambient air entering through the cold source 101 is cooled. In consequence, when it is in the part upper 54 of convection chamber 50, it has tends to descend and therefore heads towards the exit 71.
