Abstract

The direct heating circuit uses 50 mm diameter tubes in the hearth, on the back wall of the fire leading down to the fresh air inlet. Fresh air enters the pipework via a plastics tube which has a ventilator at its outside end, the ventilator accelerating the circulation of the air in the heated flow. A void regulates the flow which leads to a large diameter horizontal tube which in turn distributes the heated air through the house and the horizontal tube has shutters at either end, to allow the warm air flow to be switched on or off.

Description

La présente invention concerne un type de chauffage, permettant de récupérer environ 90 % de la chaleur d'un foyer de cheminée. The present invention relates to a type of heating, making it possible to recover approximately 90% of the heat of a fireplace hearth.

Dans les dispositifs connus de ce genre, il est per-is de récupérer la chaleur qui part dans les fumées, en passant dans un appareil qui élimine ces dernières, mais ne donne qu'lit résultat médiocre. D'autres consistent à transformer le foyer en chauffage central, ce qui nécessite une grosse transformation de l'installation et des connaissances approfondies. In known devices of this kind, it is per-is to recover the heat which leaves in the fumes, passing through an apparatus which eliminates the latter, but gives only a mediocre result. Others consist in transforming the hearth into central heating, which requires a major transformation of the installation and in-depth knowledge.

L'invention que je propose permet à la fois de récupérer un maximum de chaleur prise au coeur du foyer et de l'envoyer dans la maison avec un minimum de travaux qui peuvent être réalisés par une personne n'ayant pas de connaissances spéciales en chauffage central. The invention that I propose allows both to recover a maximum of heat taken from the heart of the home and to send it into the house with a minimum of work that can be done by a person with no special knowledge of heating central.

Pour la réalisation, il faut se procurer du tube d'acier étiré, c'est à dire sans soudure, de # 50 mm ou approchant, couper suivant la figure 1 à 450 (2) : le tube 1 formant le fond du foyer, le tube 3 formant le foyer proprement dit, et le tube 4, retour qui va chercher l'air frais soit dans le sous-sol, soit dans le vide sanitaire. For the realization, it is necessary to obtain drawn steel tube, ie without welding, of # 50 mm or approaching, cut according to figure 1 to 450 (2): the tube 1 forming the bottom of the hearth, the tube 3 forming the hearth proper, and the tube 4, return which will seek fresh air either in the basement, or in the crawl space.

Quand ces tubes sont assemblés, par exemple à la soudure à l'arc, en faire 12 sur le même modèle et les assembler comme sur la figure 2, ce qui donne un foyer de 0,60 m de large, la longueur des tuyaux étant en rapport avec la dimension de la cheminée. Une fois que tous les tubes sont soudés les uns aux autres, mettre dessus comme indiqué en figure 2 un tuyau d'acier de 8 100 mm 5, soudé sur les tubes 1, destiné à récupérer la chaleur. Ce tuyau venant de chaque côté de la cheminée avec un petit volet que l'on ferme à volonté suivant les besoins de chaleur. On peut si c'est nécessaire, ajouter un tuyau 6 de # 50 mm sur le tuyau de récupération 5 pour chauffer un étage supérieur, avec également un volet pour fermeture éventuelle. When these tubes are assembled, for example with arc welding, make 12 on the same model and assemble them as in Figure 2, which gives a hearth of 0.60 m wide, the length of the pipes being related to the size of the chimney. Once all the tubes are welded to each other, put on them as shown in Figure 2 a steel pipe of 8 100 mm 5, welded on the tubes 1, intended to recover the heat. This pipe coming from each side of the chimney with a small shutter which one closes at will according to the needs of heat. If necessary, you can add a hose 6 of # 50 mm to the recovery hose 5 to heat an upper stage, with also a shutter for possible closure.

Suivant la figure 3, l'appareil étant posé et vu en coupe, les tubes 4 plongent dans un vide 8 qui a été fait dans le sol 10 (ou le plafond si vous êtes au premier étage), ce vide étant alimenté en air frais venant du dehors par un tuyau en plnsti- que 9 de # 100 mm minimum, au bout duquel nous mettrons une grille très fine qui évitera les poussières. Nous pouvons éga liement mettre un petit ventilateur qui alimentera en air frais en début de chauffage. Il pourra être par la suite arrêté, l'air surchauffé dans les tubes fera un appel d'air suffisant. According to Figure 3, the device being placed and seen in section, the tubes 4 plunge into a vacuum 8 which has been made in the ground 10 (or the ceiling if you are on the first floor), this vacuum being supplied with fresh air coming from outside by a plastic pipe 9 of minimum # 100 mm, at the end of which we will put a very fine grid which will avoid dust. We can also put a small fan which will supply fresh air at the start of heating. It can then be stopped, the superheated air in the tubes will draw sufficient air.

D'autre part, le tube 5 est noyé dans un bloc de maçonnerie appelé contre-coeur 7, destiné à empêcher l'air frais 12 descendant dans la cheminée de refouler la fumée montante et à le faire remonter avec celle-ci entre l'avaloir 13 et le mur 11 qui constitue le fond de la cheminée.  On the other hand, the tube 5 is embedded in a block of masonry called counter-heart 7, intended to prevent the fresh air 12 descending in the chimney from repelling the rising smoke and to make it rise with it between the outlet 13 and wall 11 which constitutes the bottom of the chimney.
