Description
L'invention concerne un appareil de chauffage et de production d'un fluide de stockage d'énergie, qui comporte un réservoir dans lequel est contenu ledit fluide, une source thermique pour chauffer ce fluide, ainsi qu'une enceinte isolante dans laquelle est placé le réservoir.The invention relates to an apparatus for heating and producing an energy storage fluid, which comprises a reservoir in which said fluid is contained, a heat source for heating the fluid, and an insulating enclosure in which is placed The reservoir.
Généralement, le fluide dont il s'agit est de l'eau et c'est l'exemple qui sera pris dans l'ensemble de la présente demande.Generally, the fluid in question is water and this is the example that will be taken throughout the present application.
Dans le langage courant, un tel appareil est généralement désigné sous l'expression "ballon d'eau chaude".In common parlance, such apparatus is generally referred to as "hot water tank".
Un tel réservoir, dont la contenance peut être de quelques dizaines à quelques centaines de litres, permet de disposer d'eau chaude sanitaire.Such a tank, whose capacity may be from a few tens to a few hundred liters, provides hot water.
Généralement, ce réservoir est ceinturé par une enceinte thermiquement isolante, afin de réduire au maximum les pertes de chaleur.Generally, this tank is surrounded by a thermally insulating enclosure, in order to minimize heat loss.
Le réservoir peut aussi être utilisé pour chauffer un espace tel qu'une pièce de vie et utilise à cet effet un échangeur de chaleur hydraulique. L'échangeur de chaleur transfère la chaleur du réservoir vers des "émetteurs" de chaleur, à savoir des radiateurs, via un réseau de tubes, une pompe, etc.The tank can also be used to heat a space such as a living room and uses for this purpose a hydraulic heat exchanger. The heat exchanger transfers heat from the reservoir to heat "transmitters", ie radiators, via a network of tubes, a pump, etc.
Ce système est complexe et d'un prix de revient élevé. De plus, sa performance est faible en raison des pertes de chaleur et le radiateur.This system is complex and a high cost. In addition, its performance is low due to heat loss and radiator.
Et ceci est d'autant plus aberrant lorsque l'on a à chauffer une petite surface telle qu'une chambre, un bureau ou un studio.And this is all the more absurd when you have to heat a small area such as a bedroom, an office or a studio.
Par ailleurs, on connaît notamment par les documents
Un autre état de la technique est formé par le document
Partant de cet état de la technique, la présente invention a pour but de pallier les inconvénients énumérés ci-dessus.From this state of the art, the present invention aims to overcome the disadvantages listed above.
En d'autres termes, elle vise à fournir un appareil de chauffage et de production d'eau chaude qui soit de structure simple, économique et qui permette d'utiliser le réservoir d'eau chaude comme appareil de chauffage.In other words, it aims to provide a heater and hot water production that is simple structure, economical and allows the use of the hot water tank as a heater.
Ainsi, la présente invention se rapporte à un appareil de chauffage et de production d'un fluide de stockage d'énergie tel que de l'eau chaude, qui comporte un réservoir dans lequel est contenu ledit fluide, une source thermique pour chauffer ce fluide, ainsi qu'une enceinte isolante dans laquelle est placé le réservoir, ladite source thermique étant placée à l'intérieur du réservoir ou à l'extérieur de ladite enceinte, et la paroi de l'enceinte étant en contact avec ledit réservoir à l'exception d'au moins une région en creux constituant un canal formé dans la paroi de ladite enceinte, les extrémités opposées de ce canal communiquant respectivement avec une entrée et une sortie d'air.Thus, the present invention relates to an apparatus for heating and producing an energy storage fluid such as hot water, which comprises a reservoir in which said fluid is contained, a heat source for heating the fluid. , and an insulating enclosure in which the reservoir is placed, said thermal source being placed inside the reservoir or outside said enclosure, and the wall of the enclosure being in contact with said reservoir at the except for at least one hollow region constituting a channel formed in the wall of said enclosure, the opposite ends of this channel respectively communicating with an inlet and an air outlet.
Cet appareil est remarquable par le fait que ledit au moins un canal a une forme hélicoïdale,This apparatus is remarkable in that said at least one channel has a helical shape,
Selon d'autres caractéristiques non limitatives et avantageuses de l'invention :
- L'entrée d'air extérieur est située en partie basse de ladite enceinte, tandis que la sortie d'air est placée en partie haute de ladite enceinte,
- ladite source thermique est notamment choisie dans la liste suivante : résistance électrique, pompe à chaleur intégrée dans le réservoir, chaudière, brûleur, panneau solaire, chaudière ou pompe à chaleur déportée à l'extérieur du réservoir, poêle à bois, biomasse ou une combinaison quelconque d'au moins certains de ceux-ci,
- l'appareil comporte un outil de forçage d'air tel qu'un ventilateur, apte à forcer le passage de l'air dans le canal,
- la sortie d'air est connectée à un échangeur de chaleur air/air, tel qu'un sèche-serviette ou un radiateur à échange air/air.
- The outside air inlet is located in the lower part of said enclosure, while the air outlet is placed in the upper part of said enclosure,
- said heat source is in particular chosen from the following list: electrical resistance, integrated heat pump in the tank, boiler, burner, solar panel, boiler or remote heat pump outside the tank, wood stove, biomass or a combination any of at least some of these,
- the apparatus comprises an air forcing tool such as a fan, able to force the passage of air in the channel,
- the air outlet is connected to an air / air heat exchanger, such as a towel warmer or an air / air exchange radiator.
D'autres caractéristiques et avantages de l'invention apparaîtront à la lecture de la description détaillée qui va suivre. Elle sera faite en référence au dessin annexé dans lequel : la

Ses faces supérieure et inférieure sont respectivement référencées 20 et 21, tandis que sa surface latérale, ici cylindrique, est référencée 22. Bien entendu, toute autre forme de réservoir (ou "ballon") peut être envisagée.Its upper and lower faces are respectively referenced 20 and 21, while its lateral surface, here cylindrical, is referenced 22. Of course, any other form of tank (or "balloon") may be considered.
Toujours de manière connue, le réservoir est disposé à l'intérieur et ceinturé par une enceinte 3 en matériau qui est un isolant thermique, ceci, afin de perdre le minimum de calories emmagasinées par l'eau.Still in a known manner, the reservoir is disposed inside and surrounded by an
Le fluide contenu dans le réservoir 2 est chauffé par une source thermique 4, placée à l'intérieur du réservoir 2 (comme représenté sur les figures) ou à l'extérieur de l'enceinte 3.The fluid contained in the
Le sommet de l'enceinte 3 est référencé 30, tandis que sa base est référencée 31. Elle repose sur un socle S. Sa paroi latérale 32 présente une surface interne généralement complémentaire de celle 22 du réservoir 2.The top of the
Bien entendu, l'enceinte pourrait directement reposer au sol ou être fixée à un mur.Of course, the speaker could sit directly on the floor or be attached to a wall.
A titre d'exemple, le matériau qui constitue l'enceinte isolante 3 est de la mousse de polyuréthane. On peut bien entendu faire usage d'autre matériaux tels que du Neopor (marque déposée), du polypropylène, du polystyrène extrudé ou expansé, de la mousse phénolique ou tout type de matériau qui a une faible conductivité thermique (λ inférieure à 0.1 W/(m.K)).By way of example, the material that constitutes the
Le sommet de l'enceinte 3 supporte une pompe à chaleur 7 de type connu en soi, qui est connectée à un échangeur de chaleur hélicoïdal non représenté, également de type connu, placé dans le réservoir 2. Dans un mode de réalisation non représenté, il pourrait être placé autour de la paroi extérieure du réservoir.The top of the
La paroi du réservoir 2 de la
La section du canal 33 est semi circulaire. Toutefois, toute autre forme peut être envisagée. A titre indicatif, il pourrait s'agir d'une section rectangulaire, elliptique, rectangulaire aux coins arrondis, triangulaire, trapézoïdal, ou une combinaison de ces formes.The section of the
Le canal 33 présente la particularité d'avoir une forme hélicoïdale (voir les flèches de la
L'ouverture 321 fait office d'entrée d'air extérieur, tandis que l'ouverture 322 fait office de sortie.The opening 321 serves as an outside air inlet, while the
Dans la pratique, l'ouverture 321 fait office d'entrée d'air extérieur. Cet air est libre de circuler dans l'espace E, tout en léchant la paroi du réservoir 2. Lors de ce mouvement généralement ascendant, il se réchauffe et ressort de l'appareil par l'ouverture 322 formant sortie.In practice, the opening 321 serves as an outside air inlet. This air is free to circulate in the space E, while licking the wall of the
Dans cet exemple, un seul canal hélicoïdal est représenté. Toutefois, on peut envisager de faire usage de plusieurs canaux disposés en parallèle.In this example, only one helical channel is shown. However, it is conceivable to use several channels arranged in parallel.
Bien entendu, aussi bien l'ouverture 321 que l'ouverture 322 peuvent être équipée d'une grille ou de toute autre moyen équivalent formant filtre, de manière à ce que des polluants et/ou des insectes ne s'infiltre à l'intérieur de l'appareil.Of course, both the
On dispose, grâce à cet agencement compact qui ne nécessite pas la pose de tubes ou de radiateurs, d'une source de chauffage très pratique.Thanks to this compact arrangement which does not require the installation of tubes or radiators, a very convenient heating source is available.
L'emplacement des ouvertures 321 et 322 peut être différent de celui qui à été décrit plus haut. Toutefois, l'ouverture 322 sera préférentiellement à une hauteur plus élevée que l'ouverture 321, en raison de la capacité de l'air chaud à s'élever naturellement.The location of the
Un tel agencement est particulièrement efficace car le flux d'air qui s'engouffre dans le canal 33 parcourt un long chemin pour déboucher au niveau de l'ouverture de sortie, le long duquel l'échange thermique est maximal.Such an arrangement is particularly effective because the flow of air that rushes into the
