Description

La présente invention concerne une chaudière pour la production simultanée d'eau chaude de chauffage et d'eau chaude sanitaire avec des circuits séparés hydrauliquement. Plus particulièrement, l'invention concerne une chaudière munie d'un échangeur ayant des tubes d'eau coaxiaux à géométrie spiroidale, qui est prévue en particulier pour être utilisée en-associa- tion avec des bruleurs de gaz à aspiration d'air. The present invention relates to a boiler for the simultaneous production of hot water for heating and domestic hot water with hydraulically separated circuits. More particularly, the invention relates to a boiler provided with an exchanger having coaxial water tubes of spiral geometry, which is intended in particular to be used in association with gas burners with air intake.

Le but de la présente invention est de réaliser un dispositif du type général indiqué ci-dessus qui se distingue des dispositifs connus par des caractéristiques d'efficacité, de robustesse, de simplicité de construction et par un prix modique. The object of the present invention is to provide a device of the general type indicated above which differs from known devices by characteristics of efficiency, robustness, simplicity of construction and by a low price.

Selon la présente invention, il s'agit d'un dispositif comprenant en combinaison un tube d'eau de retour provenant de l'installation de chauffage, enroulé en spire au-dessus de la source de chaleur, et un tube de plus grand diamètre prolongeant le premier tube et formant un serpentin situé en dessous desdites spires et qui contient à l'intérieur une paire de tubes qui constituent l'aller et le retour du dispositif d'eau chaude sanitaire. According to the present invention, it is a device comprising in combination a return water tube coming from the heating installation, wound in a coil above the heat source, and a tube of larger diameter. extending the first tube and forming a coil located below said turns and which contains inside a pair of tubes which constitute the outward and return flow of the domestic hot water device.

D'autres caractéristiques et avantages de la présente invention résulteront de la description détaillée qui va suivre d'une forme préférée de réalisation de la présente invention, donnée à titre d'exemple et non limitativement, en référence aux dessins, sur lesquels
- la figure 1 est un schéma de la constitution et du fonctionnement de la chaudière selon la présente invention
- la figure 2 est une vue schématique de face d'une chaudière selon la présente invention, certaines parties ayant été sectionnées
- la figure 3 est une vue du haut de la même chaudière ; et
- la figure 4 est une vue de face d'un coté.Other characteristics and advantages of the present invention will result from the detailed description which follows of a preferred embodiment of the present invention, given by way of example and not limitatively, with reference to the drawings, in which
- Figure 1 is a diagram of the constitution and operation of the boiler according to the present invention
- Figure 2 is a schematic front view of a boiler according to the present invention, some parts having been sectioned
- Figure 3 is a top view of the same boiler; and
- Figure 4 is a front view from one side.

En référence à la figure 1, le chiffre 1 désigne l'enveloppe de la chaudière, à l'intérieur de laquelle se trouve un serpentin 2 renfermant l'eau provenant de l'installation de chauffage. Le serpentin 2 est exposé à la source de chaleur 3 constituée de préférence par un brûleur à gaz du type à aspiration d'air.  With reference to FIG. 1, the number 1 designates the envelope of the boiler, inside which is a coil 2 containing the water coming from the heating installation. The coil 2 is exposed to the heat source 3 preferably constituted by a gas burner of the air suction type.

A l'intérieur du serpentin 2, est introduite la grille 15 qui a pour but de donner une turbulence aux gaz brûlés qui la traversent, afin dvaméliorer le rendement d'échange de la partie supérieure du serpentin proprement dit. Inside the coil 2, is introduced the grid 15 which aims to give turbulence to the burnt gases passing through it, in order to improve the exchange efficiency of the upper part of the coil itself.

A la fin du serpentin 2, et en prolongement de celui-ci, est disposé un second serpentin 4 de plus grand diamètre contenant une paire de tubes 5 et 6 reliés à l'installation d'eau chaude sanitaire. Le serpentin 4 est également exposé à la source de chaleur puisqu'il se trouve en dessous du serpentin 2. At the end of the coil 2, and in extension thereof, is disposed a second coil 4 of larger diameter containing a pair of tubes 5 and 6 connected to the domestic hot water installation. The coil 4 is also exposed to the heat source since it is located below the coil 2.

Une pompe de circulation 7 fait circuler l'eau de l'installation de chauffage de manière que l'eau elle-meme retourne par le passage 8 et arrive à lwinstallae tion en sortant par le passage 9. Le sens de circulation des deux tubes 5 et 6 de l'eau chaude sanitaire est celui indiqué par les flèches de la figure 1. A circulation pump 7 circulates the water from the heating installation so that the water itself returns through the passage 8 and arrives at the installation leaving it through the passage 9. The direction of circulation of the two tubes 5 and 6 of domestic hot water is that indicated by the arrows in Figure 1.

Pour utiliser la chaudière seulement pour l'eau chaude sanitaire, on prévoit une conduite de dériw vation ou bypass 10 qui, par l'intermédiaire de la soupape il, met en court circuit les deux serpentins 2 et 4 en bloquant la conduite 9. Aux figures 2, 3 et 4, on montre une chaudière réalisée selon la présente invention. To use the boiler only for domestic hot water, a bypass line or bypass 10 is provided which, by means of the valve 11, short-circuits the two coils 2 and 4 by blocking the line 9. Aux Figures 2, 3 and 4, there is shown a boiler produced according to the present invention.

L'eau provenant de lginstallation de chauffage parcourt le tube de retour 8 et arrive dans la partie haute de la chaudière où commence le serpentin 2 qui est constitué par des spires ayant des axes horizontaux disposés au-dessus du brûleur 3 de manière à intercepter le parcours qui s'étend du brûleur 3 au conduit de fumée 12. Après la structure des spires qui constituent le serpentin-2, la conduite d'eau de chauffage présente une augmentation de diamètre indiquée par le numéro de référence 13 et forme un second serpentin inférieur 4 qui contient la paire de tubes 5 t 6 destinés à l'eau chaude sanitaire.Le serpentin inférieur A présente une extrémité fermée au point 14 de lDranchement des conduites 5 et 6 de l'eau sanitaire, et à la dernière spire, peu avant ledit point extrême, on trouve la sortie du tube d'alimentation 9 de l'eau de chauffage. The water coming from the heating installation travels through the return tube 8 and arrives in the upper part of the boiler where the coil 2 begins which is constituted by turns having horizontal axes arranged above the burner 3 so as to intercept the course which extends from the burner 3 to the smoke duct 12. After the structure of the turns which constitute the coil-2, the heating water pipe has an increase in diameter indicated by the reference number 13 and forms a second coil lower 4 which contains the pair of 5 t 6 tubes intended for domestic hot water. The lower coil A has a closed end at point 14 of the connection of domestic water pipes 5 and 6, and at the last turn, little before said end point, there is the outlet of the supply tube 9 for the heating water.

Le fonctionnement du dispositif selon la présente invention est facile à comprendre ; le serpentin 2 est exposé directement à la source de chaleur et il est chauffé par cette dernière. L'eau chaude qui provient du serpentin 2 passe dans le serpentin 4 qui lui-même est exposé au brûleur 3 et réalise l'échange thermique avec les deux tubes coaxiaux 5 et 6 qu'il continent.  The operation of the device according to the present invention is easy to understand; the coil 2 is exposed directly to the heat source and it is heated by the latter. The hot water which comes from the coil 2 passes into the coil 4 which itself is exposed to the burner 3 and performs the heat exchange with the two coaxial tubes 5 and 6 which it contains.

La spirale inférieure 4 constitue le corps principal et coopère avec le serpentin 2 pour effectuer l'échange thermique entre les gaz brûlés et l'eau, et accomplit l'échange eau-eau. En outre, le serpentin 4 est dimensionné de manière à obtenir la quantité désirée d'eau chaude pour le chauffageb
La spirale supérieure 2 a la double fonction de fournir l'échange thermique requis entre la source de chaleur et l'eau et de constituer la résistance aérodynamique appropriée aux gaz brûlés, avant que ceuxci ne débouchent dans le conduit de fumée 12. La grille 15 coopère également pour atteindre ce but.The lower spiral 4 constitutes the main body and cooperates with the coil 2 to effect the heat exchange between the burnt gases and the water, and accomplishes the water-water exchange. In addition, the coil 4 is dimensioned so as to obtain the desired quantity of hot water for heatingb
The upper spiral 2 has the dual function of providing the required heat exchange between the heat source and the water and of constituting the appropriate aerodynamic resistance to the burnt gases, before they open into the smoke duct 12. The grid 15 also cooperates to achieve this goal.

Il est évident qu'on prévoit tous les contrôles et les automatismes coopérant. pour assurer la sécurité de fonctionnement et les manoeuvres dans l'installation. It is obvious that all the cooperating controls and automatisms are provided for. to ensure operational safety and maneuvers in the installation.

Ces dispositifs ne sont pas décrits étant donné qu'ils sont connus.These devices are not described since they are known.

Bien que la présente invention ait été décrite selon sa forme préférée de réalisation, il est évident que diverses variantes d'exécution peuvent être apportées en pratique par l'homme de l'art sans sortir du cadre de protection de l'invention.  Although the present invention has been described according to its preferred embodiment, it is obvious that various variant embodiments can be made in practice by those skilled in the art without departing from the protective framework of the invention.
