Description

RADIATEUR A DOUBLE CIRCUIT DE CIRCULATION D'EAU DUAL WATER CIRCUIT RADIATOR
La présente invention concerne un radiateur de chauffage à circulation d'eau, de type chauffage central. Elle concerne plus particulièrement un radiateur de chauffage permettant de réaliser des économies d'énergie substantielles pendant les périodes dites d'intersaison, c'est-à-dire les périodes de printemps et d'automne.The present invention relates to a water circulation heating radiator, of the central heating type. It relates more particularly to a heating radiator making it possible to achieve substantial energy savings during the so-called off-season periods, that is to say the spring and autumn periods.
On sait que, depuis les années 1970, divers règlements ont conduit à minimiser les diverses déperditions qui entrent en compte dans les systèmes de distribution d'énergie. On a ainsi été amené à améliorer les isolations existant dans les logements. Cette amélioration de l'isolation a permis de diminuer la surface d'échange globale des radiateurs, essentiellement par réduction de leur épaisseur tout en maintenant, voire en augmentant, leur surface frontale. On favorise ainsi 1 ' émission par rayonnement plus confortable à l'utilisateur que le chauffage par convection. Parallèlement, des systèmes de régulation ont été mis en place, qui visent à contrôler de façon plus rigoureuse la puissance délivrée par les émetteurs.We know that, since the 1970s, various regulations have led to minimize the various losses that are taken into account in energy distribution systems. We were thus led to improve the existing insulation in the dwellings. This improvement in insulation has made it possible to reduce the overall exchange surface of the radiators, essentially by reducing their thickness while maintaining, or even increasing, their front surface. The radiation emission is thus more comfortable for the user than convection heating. At the same time, regulation systems have been put in place, which aim to more rigorously control the power delivered by the transmitters.
Les installations de chauffage central comportent ainsi des « régulateurs » abaissant progressivement la température de 1 ' eau fournie aux radiateurs lorsque la température externe s'élève jusqu'à une température dite « température de non chauffage » (TNC) . Ainsi dans le cas du chauffage d'un local à une température souhaitée, par exemple de 20°C, le régulateur abaisse la température de l'eau chaude fournie jusqu'à la valeur de 20°C et coupe le chauffage lorsque la température extérieure atteint la valeur de 20°C c'est-à-dire la TNC dans le présent exemple .Central heating installations thus include "regulators" progressively lowering the temperature of the water supplied to the radiators when the external temperature rises to a temperature known as "non-heating temperature" (TNC). Thus in the case of heating a room to a desired temperature, for example 20 ° C, the regulator lowers the temperature of the hot water supplied up to the value of 20 ° C and cuts the heating when the outside temperature reaches the value of 20 ° C, i.e. the TNC in this example.
Cependant on sait que, lorsque la température de la surface externe d'un radiateur descend à une valeur de 30°C, les occupants du local ont la sensation que ce radiateur est à l'arrêt, bien que celui-ci fournisse néanmoins de la chaleur. Il en résulte que la sensation de non chauffage sera perçue par l'occupant bien avant que la TNC de 20°C ne soit atteinte, c'est-à-dire dans le cas mentionné précédemment, aux environs d'une température extérieure de l'ordre de 15°C ainsi que montré par 1 ' expérience .However, it is known that, when the temperature of the external surface of a radiator drops to a value of 30 ° C., the occupants of the premises have the feeling that this radiator is off, although it nevertheless provides heat. It follows that the feeling of non-heating will be perceived by the occupant well before the TNC of 20 ° C is reached, that is to say in the case mentioned above, around an outside temperature of l 'around 15 ° C as shown by experience.
Cependant, dans la pratique, ces données se compliquent dans la mesure où l'on sait également qu'il existe des apports gratuits qui doivent être pris en compte dans le bilan thermique. Ces apports gratuits sont constitués d'une part par les apports thermiques du soleil mais également par les apports internes au local, c'est-à- dire ceux dus au chauffage des différents appareils électriques et électroniques des lampes d'éclairage etc... De tels apports gratuits auront un effet d'autant plus efficace que l'isolation du local sera de qualité, et que ce local sera bien orienté . On admet ainsi que pour un local dont l'isolation est faible (construction ancienne) les apports gratuits seront au minimum de l'ordre de 2°C ce qui permettrait le réglage d'une TNC à 18°C pour un chauffage à 20°C. Dans le cas d'une bonne isolation et d'une bonne orientation ces apports gratuits pourront atteindre 8°C permettant, en théorie, le réglage d'une TNC à 12°C pour un chauffage à 20°C. En pratique, le réglage d'une TNC aussi basse est tout à fait impossible, les occupants ne supportant pas que leurs radiateurs soient ou semblent froids pour d'aussi faibles températures extérieures.However, in practice, these data are complicated to the extent that we also know that there are free contributions which must be taken into account in the heat balance. These free contributions are made up on the one hand by the thermal contributions of the sun but also by the internal contributions to the room, that is to say those due to the heating of the various electric and electronic devices of the lighting lamps etc ... Such free contributions will have an effect all the more effective as the insulation of the room will be of quality, and that this room will be well oriented. It is thus accepted that for a room whose insulation is weak (old construction) the free contributions will be at least of the order of 2 ° C which would allow the setting of a TNC at 18 ° C for a heating at 20 ° vs. In the case of good insulation and good orientation, these free contributions may reach 8 ° C, allowing theory, setting a TNC at 12 ° C for heating at 20 ° C. In practice, the setting of such a low TNC is quite impossible, the occupants not supporting that their radiators are or seem cold for such low outside temperatures.
Il en résulte que, dans les périodes d'intersaison, on est non seulement contraint d'apporter aux différents locaux de la chaleur, à une période où cela n'est pas nécessaire, mais de porter la température externe des radiateurs à une température supérieure à 30°C afin que l'utilisateur prenne véritablement conscience que son local est chauffé. Il en résulte que dans ces périodes d'intersaison la température des différents locaux est souvent supérieure à ce qu'elle est pendant la période d'hiver, ce qui d'une part représente des pertes d'énergie importantes et d'autre part cause une gêne à l'utilisateur par surchauffe de son local .As a result, in off-season periods, one is not only forced to supply the different rooms with heat, at a period when this is not necessary, but to bring the external temperature of the radiators to a higher temperature. at 30 ° C so that the user realizes that his room is heated. It follows that in these off-season periods the temperature of the various premises is often higher than it is during the winter period, which on the one hand represents significant energy losses and on the other hand causes discomfort to the user due to overheating of his premises.
La présente invention a pour but de remédier à ces inconvénients en proposant un radiateur qui, d'une part, améliore le confort de l'utilisateur en fin et en début de saison de chauffe, en augmentant la quantité de chaleur fournie par rayonnement et qui, d'autre part, permet de contenter l'utilisateur en lui fournissant une sensation de chauffage de son local tout en minimisant les pertes d ' énergie .The object of the present invention is to remedy these drawbacks by proposing a radiator which, on the one hand, improves the comfort of the user at the end and at the start of the heating season, by increasing the quantity of heat supplied by radiation and which , on the other hand, allows the user to be satisfied by providing him with a feeling of heating of his room while minimizing energy losses.
La présente invention a ainsi pour objet un radiateur de chauffage à circulation d'eau chaude, comprenant une conduite d'arrivée et une conduite de sortie caractérisé en ce qu'il comporte : - au moins deux circuits distincts de circulation d'eau reliés à la même conduite d'arrivée et à la même conduite de sortie,The present invention thus relates to a heating radiator with circulation of hot water, comprising an inlet pipe and an outlet pipe characterized in that it comprises: - at least two separate circulation circuits water connected to the same inlet pipe and the same outlet pipe,
- des moyens de commutation permettant de commander l'alimentation d'une partie seulement des circuits lorsque la température de l'eau d'alimentation des circuits et/ou celle de 1 ' air du local atteint une valeur donnée de seuil.- Switching means for controlling the supply of only part of the circuits when the temperature of the supply water to the circuits and / or that of the room air reaches a given threshold value.
Dans un mode de mise en oeuvre de 1 ' invention le radiateur comprend au moins un circuit de circulation d'eau antérieur et au moins un circuit d'alimentation d'eau postérieur. Les moyens de commutation seront aptes à couper au moins l'alimentation d'un circuit de chauffage postérieur. Ces moyens de commutation pourront être de type manuel ou au contraire de type automatique et seront alors constitués de moyens thermostatiques commandés notamment par la température de l'eau d'alimentation du radiateur et qui agiront sur une soupape contrôlant 1 ' arrivée de 1 ' eau dans le circuit .In one embodiment of the invention, the radiator comprises at least one anterior water circulation circuit and at least one posterior water supply circuit. The switching means will be able to cut at least the supply of a posterior heating circuit. These switching means may be of the manual type or on the contrary of the automatic type and will then consist of thermostatic means controlled in particular by the temperature of the supply water to the radiator and which will act on a valve controlling the arrival of the water. in the circuit.
L'obturation d'au moins un circuit postérieur du radiateur pourra être effectuée par des moyens d'obturation en tout ou rien ou au contraire par des moyens d'obturation progressifs.The closure of at least one posterior circuit of the radiator may be carried out by all-or-nothing shutter means or, on the contrary, by progressive shutter means.
Le circuit de chauffage postérieur pourra être pourvu d'ailettes, ailettes qui ne seront pas reliées au circuit de chauffage antérieur.The rear heating circuit may be provided with fins, which fins will not be connected to the previous heating circuit.
On décrira ci-après, à titre d'exemples non limitatifs diverses formes d'exécution de la présente invention, en référence aux dessins annexés sur lesquels :Various embodiments of the present invention will be described below, by way of non-limiting examples, with reference to the appended drawings in which:
La figure 1 représente deux courbes significatives de la loi de chauffe d'un radiateur d'un local, à savoir la variation .de la température de l'eau de chauffage de ce radiateur en fonction de la température extérieure, respectivement sans apport de chauffage gratuit (courbe a) et avec apport de chauffage gratuit (courbe b) . Les figures 2 à 6 sont des figures schématiques partielles en coupe horizontale de différents modes de mise en oeuvre d'un radiateur suivant l'invention.FIG. 1 represents two significant curves of the heating law of a space radiator, namely the variation of the heating water temperature of this radiator as a function of the outside temperature, respectively without free heating supply (curve a) and with free heating supply (curve b). Figures 2 to 6 are partial schematic figures in horizontal section of different embodiments of a radiator according to the invention.
On a représenté sur la figure 1 la courbe représentative de la loi de chauffe d'un radiateur disposé dans un local, c'est-à-dire de la variation de la température T de 1 ' eau fournie à ce radiateur en fonction de la température t existant à l'extérieur de ce local. Le radiateur utilisé est un radiateur à circulation d'eau destiné à maintenir une température de 20°C dans le local. II est du type 75-65, c'est-à-dire que l'eau chaude arrive dans le radiateur à une température de 75°C et ressort de celui-ci à une température de 65°C, ceci en cours de fonctionnement à puissance nominale.FIG. 1 shows the curve representing the heating law of a radiator arranged in a room, that is to say of the variation of the temperature T of the water supplied to this radiator as a function of the temperature t existing outside this room. The radiator used is a water circulation radiator intended to maintain a temperature of 20 ° C in the room. It is of the 75-65 type, that is to say that the hot water arrives in the radiator at a temperature of 75 ° C. and leaves it at a temperature of 65 ° C., this during operation. at nominal power.
La courbe a représente la loi de chauffe sans apport extérieur alors que la courbe b représente la loi de chauffe nécessaire avec apport gratuit . L ' eau chaude est ainsi admise à une température maximale de 75°C (point A) et sa température est réduite progressivement par un régulateur jusqu'à une valeur minimale de 20°C, température correspondant à celle de régulation du local (point B) qui est atteint lorsque la température extérieure est de 20°C.Curve a represents the heating law without external input while curve b represents the necessary heating law with free input. Hot water is thus admitted at a maximum temperature of 75 ° C (point A) and its temperature is gradually reduced by a regulator to a minimum value of 20 ° C, temperature corresponding to that of regulation of the room (point B ) which is reached when the outside temperature is 20 ° C.
Cependant, si l'on prend totalement en considération les apports de chauffage gratuits, notamment dans le cas d'un local dont l'isolation est bonne, et en admettant que ces apports gratuits soient de 5°C, le point de non chauffage B se retrouve alors en C.However, if we take fully into account the free heating contributions, especially in the case of a room with good insulation, and admitting that these free intakes are 5 ° C, the point of no heating B is then found in C.
Si, comme on le fait en pratique on ne commence à prendre en compte les apports gratuits qu'à partir d'une température extérieure t de 5°C, la courbe b représentative de la variation de température de l'eau chaude en fonction de la température extérieure diverge alors de la courbe a au point D.If, as is done in practice, we only begin to take into account the free supplies from an outside temperature t of 5 ° C, curve b representative of the variation in hot water temperature as a function of the outside temperature then diverges from curve a at point D.
Cependant, comme on sait, ainsi qu'exposé précédemment, que l'occupant d'un local éprouve une sensation de « non chauffage » lorsque la température T de son radiateur descend à 30°C, on constate sur la courbe b que cette sensation de non chauffage lui apparaîtra lorsque la température extérieure atteindra 11°C, ce qui correspond au point E de la courbe b. On comprend dès lors qu'il sera difficile à celui-ci d'admettre qu'à une telle température son radiateur ne produise pas (apparemment) de chaleur.However, as we know, as explained above, that the occupant of a room experiences a feeling of "not heating" when the temperature T of his radiator drops to 30 ° C, we see on curve b that this feeling no heating will appear when the outside temperature reaches 11 ° C, which corresponds to point E of curve b. It is therefore understandable that it will be difficult for the latter to admit that at such a temperature his radiator does not (apparently) produce heat.
Un radiateur suivant 1 ' invention comportera plusieurs circuits distincts, et preferablement deux, à savoir un circuit alimentant sa surface antérieure et un circuit alimentant sa surface postérieure. Dans le cadre d'un fonctionnement nominal du radiateur, c'est-à-dire d'un fonctionnement à pleine puissance de celui-ci, les deux circuits sont alimentés en eau chaude et le radiateur fonctionne ainsi qu'un radiateur à eau chaude de type classique. Par contre, aux intersaisons, c'est-à-dire aux périodes précédemment mentionnées, où il n'est pas nécessaire de faire appel à la puissance thermique totale du radiateur, on alimente en eau chaude simplement la face antérieure- de celui-ci., ce qui permet pour une puissance calorifique fournie réduite, d'avoir une face antérieure à une température supérieure à celle d'un radiateur de type classique. On augmente ainsi en intersaison d'une part la proportion de chauffage produite par rayonnement et d'autre part on améliore la détection par l'utilisateur du chauffage de son radiateur.A radiator according to the invention will comprise several separate circuits, and preferably two, namely a circuit supplying its front surface and a circuit supplying its rear surface. Within the framework of a nominal operation of the radiator, that is to say an operation at full power thereof, the two circuits are supplied with hot water and the radiator operates as well as a hot water radiator of the classic type. On the other hand, at interseasons, that is to say at the periods mentioned above, where it is not necessary to call on the total thermal power of the radiator, hot water is simply supplied to the face. anterior- thereof, which allows for a reduced calorific power supplied, to have an anterior face at a temperature higher than that of a conventional radiator. In this way, the proportion of heating produced by radiation is increased in the off-season and, on the other hand, the detection by the user of the heating of his radiator is improved.
La commutation entre le fonctionnement à pleine puissance du radiateur et le fonctionnement en mode intersaison pourra être effectuée automatiquement par un dispositif de type thermostatique ou électronique, ou manuellement par l'utilisateur par 1 ' actionnement d'une simple vanne assurant l'obturation du circuit postérieur.The switching between the operation at full power of the radiator and the operation in off-season mode can be carried out automatically by a device of the thermostatic or electronic type, or manually by the user by actuation of a simple valve ensuring the obturation of the circuit. posterior.
On a représenté sur la figure 2 un radiateur 1 suivant l'invention. Celui-ci est essentiellement constitué d'une boîte à eau chaude parallélépipédique antérieure 3 et d'une boîte à eau chaude postérieure 5 de mêmes forme et dimensions. Les deux boîtes à eau chaude 3 et 5 sont réunies par des ailettes 7, qui sont respectivement soudées sur la face arrière de la boîte antérieure 3 et sur la face avant de la boîte postérieure 5. L'admission de l'eau chaude dans les boîtes 3 et 5 se fait par une canalisation 9 qui est reliée à des moyens d'alimentation en eau chaude, non représentés sur le dessin, et qui est en communication par un orifice 11 avec la boîte antérieure 3. La canalisation 9 est également en communication avec la boîte postérieure 5 par un orifice 13 qui est pourvu de moyens d'obturation. Ces moyens d'obturation sont essentiellement constitués d'un siège de clapet 14 qui entoure l'orifice 13 et d'un clapet 15 dont la base est solidaire d'une tige 17 qui est montée à coulissement dans deux supports 19 solidaires de la masse du radiateur 1. La tige 17 traverse la paroi frontale de la boîte 3 au travers de moyens d'étanchéité 21 et se termine par un bouton de commande 23.FIG. 2 shows a radiator 1 according to the invention. This essentially consists of an anterior parallelepipedal hot water box 3 and a rear hot water box 5 of the same shape and dimensions. The two hot water boxes 3 and 5 are joined by fins 7, which are respectively welded on the rear face of the front box 3 and on the front face of the rear box 5. The admission of hot water into the boxes 3 and 5 is made by a pipe 9 which is connected to hot water supply means, not shown in the drawing, and which is in communication by an orifice 11 with the front box 3. The pipe 9 is also in communication with the rear box 5 through an orifice 13 which is provided with sealing means. These shutter means essentially consist of a valve seat 14 which surrounds the orifice 13 and a valve 15 of which the base is integral with a rod 17 which is slidably mounted in two supports 19 integral with the mass of the radiator 1. The rod 17 passes through the front wall of the box 3 through sealing means 21 and ends in a control button 23.
Lorsque, arrivant à l'intersaison, l'utilisateur souhaite pouvoir réduire le chauffage de son radiateur 1, il déplace le bouton 23 dans le sens de la flèche F, ce qui a pour effet d'appliquer le clapet 15 contre le siège de clapet 14 empêchant ainsi toute arrivée d'eau chaude dans la boîte postérieure 5. Dans ces conditions le radiateur 1 ne fournit des calories qu'à partir de la boîte antérieure 3.When, arriving in the off-season, the user wishes to be able to reduce the heating of his radiator 1, he moves the button 23 in the direction of the arrow F, which has the effect of applying the valve 15 against the valve seat 14 thus preventing any arrival of hot water in the rear box 5. Under these conditions the radiator 1 supplies calories only from the front box 3.
Un tel dispositif d'obturation peut également fonctionner de façon automatique, c'est-à-dire dès que la température de l'eau admise dans le radiateur par la canalisation 9 descend au-dessous d'un seuil déterminé de température .Such a shutter device can also operate automatically, that is to say as soon as the temperature of the water admitted into the radiator through the pipe 9 drops below a determined temperature threshold.
On a représenté un tel dispositif sur la figure 3, dans lequel la tige de clapet 17 prend appui sur un élément de dilatation 18, c'est-à-dire un élément dont la nature et la longueur sont telles que, lorsque la température descend au-dessous du seuil précédemment mentionné, en raison de la rétraction de cet élément 18, le clapet 15 vient prendre appui sur le siège de clapet 14 obturant ainsi l'orifice 13 et empêchant tout passage d'eau dans la boîte postérieure 5.Such a device is shown in FIG. 3, in which the valve stem 17 is supported on an expansion element 18, that is to say an element the nature and length of which are such that, when the temperature drops below the previously mentioned threshold, due to the retraction of this element 18, the valve 15 comes to bear on the valve seat 14 thus closing the orifice 13 and preventing any passage of water in the rear box 5.
Dans les deux modes de mise en oeuvre de l'invention décrits précédemment l'obturation de l'orifice 13 assurant le passage de la canalisation 9 vers la boîte postérieure 5 s'effectue en tout ou rien. On pourrait également bien entendu suivant 1 ' invention prévoir des moyens d'obturation proportionnels qui se fermeraient progressivement au fur et à mesure que la température de l'eau admise par la canalisation 9 baisse.In the two embodiments of the invention described above, the closure of the orifice 13 ensuring the passage of the pipe 9 towards the rear box 5 is all or nothing. One could of course also according to the invention provide proportional sealing means which would gradually close as the temperature of the water admitted by the line 9 drops.
On a représenté un tel dispositif de façon schématique sur la figure 4. Sur celle-ci l'orifice 13 comporte un siège de clapet 14 ' en forme de tronc de cône et le clapet 15 ' possède quant à lui une forme tronconique complémentaire de celle du siège de clapet 14 ' . La tige de clapet 17 est reliée à des moyens d'asservissement 25 qui sont commandés par des moyens électroniques d'analyse qui prennent leur information quant à la température T de l'eau admise au moyen d'un capteur 27 qui est disposé dans le circuit d'admission de la canalisation 9. Un tel dispositif d'asservissement en température est tel qu'il permet une fermeture progressive du clapet 15 ' lorsque la température de l'eau admise par la canalisation 9 décroît. On diminue ainsi progressivement la section de passage de 1 ' orifice 13 , ce qui a pour effet de diminuer progressivement la quantité de chaleur fournie par la boîte arrière 5.Such a device is represented schematically in FIG. 4. On this one the orifice 13 comprises a valve seat 14 ′ in the form of a truncated cone and the valve 15 ′ has a frustoconical shape complementary to that of the valve seat 14 '. The valve stem 17 is connected to servo means 25 which are controlled by electronic analysis means which take their information as to the temperature T of the water admitted by means of a sensor 27 which is arranged in the pipe intake circuit 9. Such a temperature control device is such that it allows progressive closing of the valve 15 ′ when the temperature of the water admitted by the pipe 9 decreases. The passage section of the orifice 13 is thus progressively reduced, which has the effect of gradually decreasing the amount of heat supplied by the rear box 5.
Dans un mode de mise en oeuvre représenté sur la figure 5, on diminue la quantité de chaleur fournie par la boîte postérieure 5 en isolant les ailettes 7 de la boîte antérieure 3. On comprend que, dans ces conditions, lorsque l'on obture l'orifice d'admission 13 on diminue de façon plus importante la quantité de chaleur fournie par cette dernière. Dès lors, pour une puissance calorifique constante fournie par le radiateur 1, il est ainsi possible -d'admettre de.l'eau à une température plus élevée dans la boîte antérieure 3.In an embodiment shown in FIG. 5, the quantity of heat supplied by the rear box 5 is reduced by isolating the fins 7 from the front box 3. It is understood that, under these conditions, when the l 'inlet 13 is reduced more significantly the amount of heat supplied by the latter. Therefore, for a constant calorific power supplied by the radiator 1, it is thus possible -to admit water at a higher temperature in the front box 3.
On pourrait également, dans un mode de mise en oeuvre non représenté sur le dessin, prévoir un ventilateur qui serait disposé de façon à collecter la chaleur dispensée par la boîte postérieure 5 et ceci à puissance égale du radiateur, de façon à augmenter encore le pourcentage de chaleur fournie par ladite partie postérieure.One could also, in an embodiment not shown in the drawing, provide a fan which would be arranged so as to collect the heat supplied by the rear box 5 and this at equal power from the radiator, so as to further increase the percentage heat supplied by said rear part.
Suivant l'invention, la température à partir de laquelle on « bascule » l'alimentation en eau chaude sera fonction du rapport de puissance qui existe entre les faces avant et arrière du radiateur, et de l'importance des apports gratuits dans le local concerné.According to the invention, the temperature from which the hot water supply is “switched on” will depend on the power ratio which exists between the front and rear faces of the radiator, and on the importance of the free supplies in the room concerned. .
Dans un mode de mise en oeuvre de 1 ' invention représentée sur la figure 6, la température de basculement sera réglable à partir de l'extérieur du radiateur.In an embodiment of the invention shown in FIG. 6, the tilting temperature will be adjustable from the outside of the radiator.
Ainsi, on a représenté sur la figure 6 une telle variante de mise en oeuvre .Thus, there is shown in Figure 6 such an implementation variant.
Sur cette dernière le radiateur comprend comme précédemment une boîte à eau chaude antérieure 3 , et une boîte à eau chaude postérieure 5 qui sont respectivement alimentées par une canalisation d'alimentation externe 9. Le circuit d'alimentation postérieur est alimenté à partir d'un orifice 13 fermé par un clapet 15 supporté par une tige de clapet 17. Celle-ci vient se visser dans des écrous 20 solidaires du boîtier du radiateur par des montants 19. La tige se termine à l'extérieur par un bouton de commande 23'. La tige de clapet 17 est pourvue, entre les deux écrous support d'un élément thermostatique 18 permettant d'assurer l'obturation du circuit postérieur 3 lorsque -la température de l'eau arrivant par le canal 9 descend au-delà d'un certain seuil. Le déplacement réglable du clapet 15 permet ainsi de modifier la température à partir de laquelle cette obturation sera réalisée.On the latter, the radiator comprises as before an anterior hot water box 3, and a posterior hot water box 5 which are respectively supplied by an external supply pipe 9. The rear supply circuit is supplied from a orifice 13 closed by a valve 15 supported by a valve rod 17. The latter is screwed into nuts 20 secured to the radiator housing by uprights 19. The rod ends on the outside by a control button 23 ' . The valve stem 17 is provided, between the two support nuts, with a thermostatic element 18 enabling the posterior circuit to be closed. 3 when the temperature of the water arriving through the channel 9 drops beyond a certain threshold. The adjustable movement of the valve 15 thus makes it possible to modify the temperature from which this shutter will be produced.
Bien entendu les moyens de commutation peuvent également être en relation avec des moyens capteurs sensibles à la température de 1 ' air du local . Of course the switching means can also be in relation to sensor means sensitive to the temperature of the room air.
