Description

APPAREIL DE CHAUFFAGE RAYONNANT COMPRENANT UN ELEMENT DE CHAUFFAGE A INERTIE THERMIQUE  RADIANT HEATING APPARATUS COMPRISING A THERMAL INERTIA HEATING ELEMENT
La présente invention concerne un appareil de chauffage rayonnant comprenant un élément de chauffage à inertie thermique. Dans le secteur du chauffage domestique, un appareil de chauffage rayonnant est un appareil, dont l'effet de chauffage sur l'environnement est majoritairement produit par une transmission de la chaleur par rayonnement. À cette fin ledit appareil de chauffage comprend des éléments actifs favorisant ce mode de transmission de chaleur. Un des inconvénients des appareils de chauffage par rayonnement de l'art antérieur est le fait que les éléments actifs qui les composent n'ont que très peu d'inertie thermique, c'est-à-dire que leur capacité à stocker de la chaleur pour la restituer petit à petit est très faible. The present invention relates to a radiant heater comprising a thermal inertia heating element. In the domestic heating sector, a radiant heater is a device, the heating effect of which on the environment is mainly produced by a radiation heat transmission. For this purpose said heater comprises active elements favoring this mode of heat transmission. One of the drawbacks of radiation heaters of the prior art is that the active elements that compose them have very little thermal inertia, that is to say that their ability to store heat to restore it little by little is very small.
Toujours selon l'art antérieur le pilotage des éléments chauffant de l'appareil est généralement basé sur une régulation en mode tout ou rien, comprenant des cycles où l'élément chauffant est alimenté en énergie pour délivrer sa puissance de chauffage maximale, suivi d'un cycle où ledit élément chauffant n'est plus alimenté en énergie. Still according to the prior art the control of the heating elements of the apparatus is generally based on a control in all or nothing mode, comprising cycles where the heating element is supplied with energy to deliver its maximum heating power, followed by a cycle where said heating element is no longer supplied with energy.
Ce mode de régulation de l'art antérieur utilise par exemple des dispositifs interrupteurs, tels que des thyristors, commandés par des dispositifs de régulation, agissant sur l'alimentation électrique des éléments chauffants équipant les appareils de chauffage. Ces thyristors ont des cycles d'ouverture et de fermeture rapides de sorte qu'en cours de fonctionnement, un tel appareil de chauffage rayonnant, du fait de sa technologie de régulation en mode tout ou rien et de sa faible inertie thermique, présente des fluctuations de température très rapides pour les éléments chauffants impliquant, pour ces derniers, de fortes contraintes mécaniques et à une source d'inconfort pour l'utilisateur d'un tel appareil. This regulation mode of the prior art uses, for example, switching devices, such as thyristors, controlled by regulating devices, acting on the power supply of the heating elements equipping the heating apparatus. These thyristors have fast opening and closing cycles so that, during operation, such a radiant heater, because of its on / off regulation technology and its low thermal inertia, presents fluctuations. very fast temperature for the heating elements involving, for the latter, high mechanical stress and a source of discomfort for the user of such a device.
L'utilisation d'un chauffage par rayonnement selon l'art antérieur, est également susceptible de générer de l'inconfort thermique lorsque ledit appareil est alimenté par une source d'énergie, notamment électrique, susceptible de subir des délestages. Les conditions de délestage sont fonction des pays et des opérateurs et visent généralement à lisser la consommation énergétique et à adapter la demande aux capacités de production de l'opérateur. À titre d'exemple non limitatif, un principe de délestage rencontré au Japon sous le nom de « snow melting » comprend une succession de périodes d'alimentation et de périodes de coupure, en alternance. Cette alternance d'alimentation du chauffage génère des fluctuations de température très importantes dans les appareils de chauffage domestique, source d'inconfort pour l'utilisateur qui ressent une sensation de froid dans l'habitation équipée des appareils de chauffage domestiques, très rapidement après la coupure de l'alimentation du circuit de chauffage. The use of radiation heating according to the prior art is also likely to generate thermal discomfort when said apparatus is powered by a source of energy, especially electrical power, capable of to have load shedding Load shedding conditions are country and operator specific and generally aim at smoothing energy consumption and adjusting demand to the operator's production capacity. As a non-limitative example, a shedding principle encountered in Japan under the name of "snow melting" includes a succession of feeding periods and break periods, alternately. This alternation of heating power generates very large temperature fluctuations in domestic heating appliances, which is a source of discomfort for the user who feels a cold sensation in the home equipped with domestic heating appliances, very quickly after the cut off the power supply to the heating circuit.
Pour remédier à cet inconvénient de l'art antérieur, une solution simple est de surchauffer l'habitation en augmentant la consigne de fonctionnement des appareils de chauffage juste avant la coupure du circuit électrique de chauffage. Cette surchauffe permet ainsi à l'habitation de maintenir une température élevée durant toute la phase de coupure d'alimentation électrique. To overcome this disadvantage of the prior art, a simple solution is to overheat the house by increasing the operating set point of the heaters just before the shutdown of the electric heating circuit. This overheating thus allows the house to maintain a high temperature throughout the power supply shutdown phase.
L'inconvénient d'une telle solution est évidemment une surconsommation d'énergie, et donc une surcharge aggravée du réseau électrique. The disadvantage of such a solution is obviously overconsumption of energy, and therefore an aggravated overload of the electrical network.
Pour éviter ces inconvénients, une solution de l'art antérieur consiste à lisser la température radiative ressentie par les utilisateurs. À cette fin, la durée des cycles de régulation tout ou rien est réduite.To avoid these disadvantages, a solution of the prior art is to smooth the radiative temperature felt by users. For this purpose, the duration of on-off control cycles is reduced.
Toutefois, cette solution engendre une surchauffe importante des interrupteurs, notamment des thyristors, susceptible de détériorer ces derniers. However, this solution generates significant overheating switches, including thyristors, likely to deteriorate them.
Une autre solution de l'art antérieur pour lisser la température radiative ressentie par les utilisateurs est d'équiper les appareils de chauffage avec des éléments chauffants radiatifs ayant beaucoup d'inertie, c'est-à-dire ayant une grande capacité à stocker de la chaleur pour la restituer petit à petit. Another solution of the prior art for smoothing the radiative temperature experienced by the users is to equip the heaters with radiative heating elements having a lot of inertia, that is to say having a large capacity to store the heat to restore it little by little.
Cependant, l'utilisation d'éléments chauffants présentant beaucoup d'inertie augmente également le temps de montée en température desdits éléments. Or il est important, lors de la remise en alimentation du circuit de chauffage, que les appareils de chauffage reviennent rapidement à température pour fournir au plus vite à l'utilisateur un confort optimum. De plus, les éléments chauffants à inertie existants ont des caractéristiques radiatives moins intéressantes que celles des résistances chauffantes sans inertie. However, the use of heating elements with a lot of inertia also increases the temperature rise time of said elements. However, when heating the heating circuit, it is important that the heaters come back to temperature quickly. to provide the user with optimum comfort as quickly as possible. In addition, the existing inertial heating elements have radiative characteristics less interesting than those of the heating resistors without inertia.
L'invention vise à résoudre les inconvénients de l'art antérieur et concerne à cette fin un appareil de chauffage par rayonnement, dit hybride : The invention aims to solve the disadvantages of the prior art and concerns for this purpose a radiative heating apparatus, said hybrid:
- un bâti dont une face arrière du bâti est apte à être fixée à une paroi, le bâti étant relié à un élément rayonnant formant une façade de l'appareil ; a frame whose rear face of the frame is adapted to be fixed to a wall, the frame being connected to a radiating element forming a front of the apparatus;
- un premier élément chauffant sans inertie ; a first heating element without inertia;
- un deuxième élément de chauffage à inertie ; ledit élément chauffant sans inertie étant configuré pour pouvoir, d'une part, chauffer l'élément rayonnant, d'autre part, chauffer le deuxième élément de chauffage à inertie par convection naturelle. a second element for heating with inertia; said heating element without inertia being configured to be able, on the one hand, to heat the radiating element, on the other hand, to heat the second natural convection heating element with inertia.
Ainsi, la vitesse de montée en température de l'élément de chauffag à inertie est accélérée par l'action de l'élément de chauffage sans inertie et la température radiative ressentie par l'utilisateur est lissée par l'action dudit élément de chauffage à inertie, de sorte que l'appareil de chauffage rayonnant selon l'invention présente une capacité thermique inertielle avantageuse tout en conservant une bonne réactivité de chauffe. Thus, the rate of rise in temperature of the inertia heating element is accelerated by the action of the heating element without inertia and the radiative temperature felt by the user is smoothed by the action of said heating element to inertia, so that the radiant heater according to the invention has an advantageous inertial heat capacity while maintaining a good heating reactivity.

L'invention est exposée ci-après selon ses modes de réalisation préférés, nullement limitatifs, et en référence à la figure 1 illustrant une vue à caractère schématique et en coupe d'un appareil de chauffage par rayonnement selon l'invention. Advantageously, the shell is constituted by an aluminum profile. Advantageously, the compartments are open at at least one of their ends to allow filling of the inertia material and cooperate with a closure device. Advantageously, the inertial heating element is closed at each of its ends by a closure device and is configured to be fixed inside the radiant heater by means of fastening means which are provided with said closure devices. The invention is explained below according to its preferred embodiments, in no way limiting, and with reference to Figure 1 illustrating a schematic and sectional view of a radiant heating apparatus according to the invention.
Selon l'invention, l'appareil de chauffage hybride par rayonnement 10 pour le chauffage d'une pièce comprend : According to the invention, the hybrid radiation heater 10 for heating a room comprises:
- un bâti 1 1 dont une face arrière 12 du bâti est apte à être fixée à une paroi de la pièce, le bâti étant relié à un élément rayonnant 13 formant une façade de l'appareil ; - A frame 1 1, a rear face 12 of the frame is adapted to be fixed to a wall of the room, the frame being connected to a radiating element 13 forming a front of the apparatus;
- un premier élément chauffant sans inertie 14 ; - un deuxième élément de chauffage à inertie 1 . a first heating element without inertia 14; a second inertia heating element 1.
L'élément chauffant sans inertie 14 est configuré pour pouvoir, d'une part, chauffer l'élément rayonnant 13, d'autre part, chauffer le second élément de chauffage à inertie 1 par convection naturelle. The heating element without inertia 14 is configured to be able, on the one hand, to heat the radiating element 13, on the other hand, to heat the second inertia heating element 1 by natural convection.
Selon un exemple de réalisation, les éléments chauffants à inertie 1 et sans inertie 14 sont placés l'un au-dessus de l'autre à l'intérieur de l'appareil de chauffage rayonnant 10, l'élément actif à inertie 1 étant placé au-dessus de l'élément chauffant sans inertie 14. According to an exemplary embodiment, the inertia heaters 1 and without inertia 14 are placed one above the other inside the radiant heater 10, the active element with inertia 1 being placed above the heating element without inertia 14.
L'élément de chauffage à inertie 1 comprend : The inertia heating element 1 comprises:
- une source de chaleur 2 par exemple constituée par une résistance électrique ; a heat source 2, for example constituted by an electrical resistance;
- une coque 3 apte à être chauffée par la source de chaleur et définissant au moins un compartiment 4 destiné à recevoir un matériau à inertie 5. La coque 3 est configurée, d'une part, pour transmettre de la chaleur à son environnement extérieur et, d'autre part, pour conduire la chaleur au matériau à inertie et chauffer ce dernier. a shell 3 capable of being heated by the heat source and defining at least one compartment 4 intended to receive an inertia material 5. The shell 3 is configured, on the one hand, to transmit heat to its external environment and, on the other hand, to conduct heat to the inertia material and heat the latter.
De manière avantageuse, lorsque l'élément de chauffage à inertie possède un seul compartiment 4, ce dernier est configuré de sorte à être centré sur la source de chaleur 2, de sorte que ce dernier chauffe uniformément ledit compartiment ainsi que le matériau à inertie 5 qu'il renferme. Advantageously, when the inertia heating element has a single compartment 4, the latter is configured so as to be centered on the heat source 2, so that the heat source 2 uniformly heats said compartment and the inertia material 5 that it contains.
Selon l'exemple de réalisation illustré, la coque 3 définit deux compartiments 4 disposés de part et d'autre de la résistance électrique 2. Ces compartiments présentent une section de forme pétaloïde dont la largeur décroît en s'éloignant de la résistance chauffante 1 . Ainsi, cette forme particulière rend la température de surface de la source de chaleur 2 plus homogène dans les phases de chauffage car la quantité de matière à inertie est plus importante à l'endroit où le potentiel de stockage de chaleur est plus important, c'est-à-dire à proximité de ladite source de chaleur. Ce potentiel décroît en s'éloignant de ladite source de chaleur de sorte que, inversement, la quantité de matière à inertie est moins importante à l'endroit où le potentiel de stockage de chaleur est le moins important, c'est-à-dire à distance de ladite source de chaleur. According to the exemplary embodiment illustrated, the shell 3 defines two compartments 4 disposed on either side of the electrical resistance 2. These compartments have a section of petaloid shape whose width decreases away from the heating resistor 1. Thus, this particular shape makes the surface temperature of the heat source 2 more homogeneous in the heating phases because the quantity of inertia material is greater at the location where the heat storage potential is greater. that is, near said heat source. This potential decreases by moving away from said heat source so that, conversely, the quantity of inertia material is smaller at the location where the heat storage potential is the least important, that is to say away from said heat source.
Selon un exemple de réalisation non illustré, chaque compartiment 4 est cloisonné de sorte à former une pluralité de chambres à l'intérieur de chaque compartiment 4. De telles cloisons définissent des canaux thermiques dans les compartiments 4 permettant d'augmenter la conductivité thermique dans le matériau inertiel. According to an embodiment not shown, each compartment 4 is partitioned so as to form a plurality of chambers inside each compartment 4. Such partitions define thermal channels in the compartments 4 to increase the thermal conductivity in the inertial material.
De manière avantageuse, la coque 3 est réalisée en tout matériau présentant de bonnes caractéristiques de conduction thermique et une faible émissivité. Selon un mode de réalisation avantageux, ladite coque 3 est réalisée dans un matériau présentant une émissivité comprise entre 0 et 0,5. Préférentiellement, ladite coque est constituée par un profilé en aluminium. Advantageously, the shell 3 is made of any material having good thermal conduction characteristics and low emissivity. According to an advantageous embodiment, said shell 3 is made of a material having an emissivity of between 0 and 0.5. Preferably, said shell is constituted by an aluminum profile.
De plus, pour augmenter la surface d'échange thermique de l'élément de chauffage à inertie, au moins une portion de ladite coque 3 présente une surface rugueuse définissant des vaguelettes ou ailettes, améliorant ainsi le transfert thermique entre l'élément chauffant et son environnement. Avantageusement, l'élément de chauffage à inertie est positionné dans l'appareil de chauffage selon l'invention de sorte que cette surface rugueuse soit disposée en regard de la façade 13. Dans un mode de réalisation, le matériau à inertie 5 contenu dans les compartiments 4 est un solide tel que de la céramique ou de la fonte. Dans un autre mode de réalisation, le matériau à inertie est un liquide tel qu'un fluide caloporteur (par exemple une huile végétale ou minérale). Dans encore un autre mode de réalisation, les compartiments 4 reçoivent une combinaison d'un matériau à inertie solide et d'un matériau à inertie liquide ou d'un matériau à changement de phase. Dans un mode de réalisation préféré, le matériau inertiel 5 est de la roche de silice pure, calcinée et broyée à granulométrie variable. En effet, la roche de silice pure est un matériau présentant de bonnes qualités inertielles. De plus, la granulométrie variable permet d'optimiser le remplissage des compartiments 4. In addition, to increase the heat exchange surface of the inertia heating element, at least a portion of said shell 3 has a rough surface defining wavelets or fins, thus improving the transfer between the heating element and its environment. Advantageously, the inertia heating element is positioned in the heating apparatus according to the invention so that this rough surface is disposed facing the facade 13. In one embodiment, the inertia material 5 contained in the compartments 4 is a solid such as ceramic or cast iron. In another embodiment, the inertia material is a liquid such as a coolant (for example a vegetable or mineral oil). In yet another embodiment, the compartments 4 receive a combination of a solid inertia material and a liquid inertia material or a phase change material. In a preferred embodiment, the inertial material is pure silica rock, calcined and milled to a variable size. Indeed, pure silica rock is a material with good inertial qualities. In addition, the variable particle size makes it possible to optimize the filling of the compartments 4.
L'élément de chauffage à inertie ainsi réalisé est tel que la source de chaleur 2 n'est pas en contact avec le matériau à inertie 5. De la sorte, la source de chaleur 2 chauffe dans un premier temps la coque 3, puis la chaleur est stockée dans le matériau inertiel, ce qui procure une meilleure réactivité de l'élément de chauffage à inertie. The inertia heating element thus produced is such that the heat source 2 is not in contact with the inertia material 5. In this way, the heat source 2 initially heats the shell 3, then the heat is stored in the inertial material, which provides a better reactivity of the inertia heating element.
Avantageusement, les compartiments 4 sont ouverts à au moins l'une de leurs extrémités pour permettre le remplissage du matériau à inertie et coopèrent avec un dispositif de fermeture, encore appelé bouchon dans le présent exposé. Ces bouchons sont réalisés dans un matériau dont le coefficient de dilatation est inférieur à celui du matériau dans lequel est réalisée la coque 3, de sorte à améliorer la fermeture des compartiments 4 par la réaction de dilatation des matériaux constituant l'élément de chauffage à inertie 1 lors de sa montée en température. Advantageously, the compartments 4 are open at at least one of their ends to allow the filling of the inertia material and cooperate with a closure device, also called plug in the present disclosure. These plugs are made of a material whose coefficient of expansion is less than that of the material in which the shell 3 is made, so as to improve the closure of the compartments 4 by the expansion reaction of the materials constituting the inertia heating element. 1 when it rises in temperature.
De préférence, les bouchons destinés à fermer les compartiments 4 à au moins l'une de leurs extrémités sont réalisés en acier. En effet, la coque étant réalisée en aluminium, elle présente un coefficient de dilatation supérieur à celui des bouchons exécutés en acier. Ainsi, lorsque l'élément de chauffage à inertie 1 chauffe, l'aluminium constituant la coque chauffe et se dilate de manière plus importante que l'acier constituant les bouchons, ce qui a pour effet d'améliorer la fermeture des compartiments 4. Cette configuration permet d'assurer une bonne étanchéité des compartiments 4. Toutefois, pour améliorer cette étanchéité, les compartiments sont munis de joints d'étanchéité. Preferably, the plugs intended to close the compartments 4 at at least one of their ends are made of steel. Indeed, the hull being made of aluminum, it has a coefficient of expansion greater than that plugs made of steel. Thus, when the inertia heating element 1 heats up, the aluminum constituting the shell heats and expands more significantly than the steel constituting the plugs, which has the effect of improving the closure of the compartments 4. configuration ensures a good seal compartments 4. However, to improve this seal, the compartments are provided with gaskets.
Dans un mode de réalisation, les bouchons sont fixés, à demeure ou de manière amovible à la coque 3, par exemple par sertissage ou par vissage. De manière avantageuse, le dispositif de fermeture comporte des moyens de fixation (non représentés) permettant la fixation de l'élément de chauffage à inertie à l'intérieur de l'appareil de chauffage rayonnant selon l'invention. In one embodiment, the plugs are fixed, permanently or removably to the shell 3, for example by crimping or screwing. Advantageously, the closure device comprises fastening means (not shown) for fixing the inertia heating element inside the radiant heating apparatus according to the invention.
Ces moyens de fixation sont configurés pour supporter le poids de l'élément de chauffage à inertie. Ces moyens de fixation présentent la flexibilité nécessaire pour absorber la dilatation thermique lors du chauffage dudit élément. Ces moyens de fixation sont positionnés perpendiculairement à la direction de la dilatation de la coque de l'élément chauffant à inerte permettant ainsi de supprimer les effets de glissement de l'élément de chauffage à inertie dus à la dilatation pouvant générer des bruits indésirables. L'élément chauffant sans inertie 14, par exemple constitué par un profilé en aluminium 15 classique traversé par une résistance électrique 16, est configuré, d'une part, pour chauffer l'élément rayonnant 13 et par conséquent, chauffer par rayonnement la pièce dans lequel l'appareil est installé et les personnes à proximité, et, d'autre part, pour chauffer, par convection naturelle, le second élément de chauffage à inertie 1 . These fixing means are configured to support the weight of the inertia heating element. These fixing means have the flexibility necessary to absorb the thermal expansion during heating of said element. These fixing means are positioned perpendicularly to the direction of the expansion of the shell of the inert heating element thus eliminating the sliding effects of the inertia heating element due to expansion that can generate unwanted noise. The non-inertia heating element 14, for example constituted by a conventional aluminum section through which an electrical resistor 16 passes, is configured, on the one hand, to heat the radiating element 13 and consequently to radially heat the room in which the apparatus is installed and persons nearby, and, secondly, to heat, by natural convection, the second inertia heating element 1.
Lors de la mise en marche de l'appareil de chauffage 10, l'élément chauffant sans inertie 14 monte très rapidement en température et chauffe ainsi rapidement la pièce par rayonnement de sorte à fournir un certain confort de chauffage à l'utilisateur. En effet, le chauffage par rayonnement chauffe directement les objets et les personnes qui reçoivent ledit rayonnement, en général infrarouge. Le chauffage par rayonnement donne donc rapidement à l'utilisateur une sensation de chaleur sans même que l'air qui l'entoure ne soit chaud. When the heater 10 is turned on, the non-inertia heating element 14 rises very rapidly in temperature and thus rapidly heats the room by radiation so as to provide the user with a certain heating comfort. Indeed, the radiant heating directly heats the objects and the people who receive said radiation, in general infrared. Radiant heating therefore quickly gives the user a feeling of warmth without the surrounding air being hot.
De plus, l'élément chauffant sans inertie étant disposé en dessous de l'élément de chauffage à inertie 1 , ce dernier est chauffé par convection naturelle de l'air circulant à l'intérieur de l'appareil de chauffage 10. L'air chauffé par l'élément chauffant sans inertie 14 situé en partie basse de l'appareil de chauffage, monte et cède ses calories à l'élément de chauffage à inertie 1 situé en partie haute de l'appareil de chauffage 10. Ainsi, la montée en température de l'élément de chuaffage à inertie 1 est accélérée. In addition, the heating element without inertia being disposed below the inertia heating element 1, the latter is heated by natural convection of the air flowing inside the heater 10. The air heated by the heating element without inertia 14 located in the lower part of the heater, rises and gives up its calories to the inertia heating element 1 located in the upper part of the heater 10. Thus, the rise the temperature of the inertial choke element 1 is accelerated.
Sous l'action du chauffage par conduction de la coque 3 chauffée à la fois par la résistance électrique 2 et la convection thermique susmentionnée, le matériau à inertie 5 contenu dans les compartiments 4 emmagasine de l'énergie thermique de sorte que lorsque l'appareil de chauffage atteint une température une température de consigne de fonctionnement et entame son fonctionnement par cycles, par exemple commandé par des thyristors connus en soi, ledit matériau à inertie 5 restitue lentement l'énergie thermique stockée, ce qui a pour effet de lisser la température radiative ressentie par l'utilisateur. Under the action of conductive heating of the shell 3 heated by both the electrical resistance 2 and the aforementioned thermal convection, the inertial material 5 contained in the compartments 4 stores thermal energy so that when the device The heating element reaches a temperature at a set operating temperature and starts its operation in cycles, for example controlled by thyristors known per se, said inertial material 5 slowly restores the stored thermal energy, which has the effect of smoothing the temperature. radiative felt by the user.
