De tels récepteurs sont en particulier :

  • les primaires d'échangeurs thermiques propres à chauffer des ballons d'eau chaude destinés au puisage domestique, notamment pour la toilette, la cuisine...,
  • les primaires d'échangeurs thermiques eau-air destinés à un chauffage à air chaud,
  • ou encore les radiateurs d'une installation de chauffage central à eau chaude.
Such receivers are in particular:
  • the primary heat exchangers suitable for heating hot water tanks intended for domestic drawing, in particular for the toilet, the kitchen ...,
  • the primers of water-air heat exchangers intended for hot air heating,
  • or the radiators of a hot water central heating installation.

Dans les modes de réalisation actuellement connus des circuits du genre en question, ceux-ci sont fabriqués et montés individuellement à la demande, en fonction des caractéristiques des installations à établir, ce qui est long et coûteux.In the currently known embodiments of circuits of the kind in question, these are manufactured and mounted individually on demand, depending on the characteristics of the installations to be set up, which is long and costly.

L'invention a pour but de simplifier la fabrication et le montage des circuits du genre en question en regroupant certains de leurs éléments constitutifs sous la forme de modules se prêtant à des fabrications en grandes séries et à des montages extrêmement simples.The invention aims to simplify the manufacture and assembly of circuits of the kind in question by grouping some of their constituent elements in the form of modules suitable for mass production and extremely simple assemblies.

A cet effet, les circuits du genre en question, destinés à être adaptés sur les faces terminales coplanaires de deux brides raccordées respectivement à la sortie d'eau chaude d'un générateur de calories et au retour d'eau relativement froide vers ce générateur, sont essentiellement caractérisés selon l'invention en ce qu'ils comprennent :

  • d'une part, au moins un module comportant deux tronçons de tube rectilignes identiques de relativement gros diamètre terminés par des brides, une structure rigide d'entretoisement reliant entre eux ces deux tronçons de façon qu'ils soient disposés parallèlement entre eux avec les plans terminaux de leurs brides coplanaires deux à deux, une conduite s'étendant entre les deux tronçons et de diamètre plus petit que ceux-ci, et un équipement hydraulique comprenant au moins une pompe de circulation montée sur ladite conduite,
  • et, d'autre part, un raccord tubulaire en U présentant un diamètre égal à celui de chacun des tronçons ci-dessus et terminé par deux brides adaptables sur les deux brides situées d'un même côté d'un module tel que défini ci-dessus.
To this end, the circuits of the type in question, intended to be adapted on the coplanar end faces of two flanges connected respectively to the hot water outlet of a calorie generator and to the return of relatively cold water to this generator, are essentially characterized according to the invention in that they comprise:
  • on the one hand, at least one module comprising two identical rectilinear tube sections of relatively large diameter terminated by flanges, a rigid bracing structure connecting these two sections together so that they are arranged parallel to each other with the end planes of their coplanar flanges two by two, a pipe extending between the two sections and of smaller diameter than these, and hydraulic equipment comprising at least one circulation pump mounted on said pipe,
  • and, on the other hand, a U-shaped tubular connection having a diameter equal to that of each of the above sections and terminated by two flanges adaptable to the two flanges located on the same side of a module as defined above. above.

Dans le cas le plus général, chaque circuit comprend une pluralité de modules tels que définis ci-dessus dont les tronçons tubulaires respectifs sont raccordés en série au niveau de leurs brides de façon à former ensemble deux tubes rectilignes parallèles rigides s'étendant entre le générateur de calories et le raccord en U.In the most general case, each circuit comprises a plurality of modules as defined above, the respective tubular sections of which are connected in series at their flanges so as to form together two rigid parallel rectilinear tubes extending between the generator. of calories and the U-shaped connection.

Pour ce qui est des équipements hydrauliques compris par les modules du genre en question, on les agence avantageusement selon l'une ou l'autre des deux façons suivantes, selon que le module considéré est destiné à des puisages d'eau chaude ou à un chauffage central :

  • dans le premier cas, l'équipement monté sur la conduite comprend en série une pompe de circulation, un clapet anti-retour et le circuit primaire d'un échangeur de chaleur,
  • dans le second cas, l'équipement monté sur la conduite comprend une vanne à trois voies dont ladite conduite constitue deux des trois voies, savoir une première voie reliée au tronçon tubulaire d'eau chaude et une seconde voie reliée au tronçon tubulaire d'eau refroidie, une première dérivation équipée d'une pompe de circulation, dont une extrémité constitue la troisième voie de la vanne et dont l'autre extrémité constitue un plot de départ d'eau chaude propre à être raccordé à l'extrémité amont d'une canalisation de chauffage central comprenant au moins un radiateur, et une deuxième dérivation dont une extrémité est raccordée à un point de la portion, de la conduite ci-dessus, constituant la seconde voie de la vanne et dont l'autre extrémité constitue un plot de retour d'eau refroidie propre à être raccordé à l'extrémité aval de la susdite canalisation de chauffage central.
As regards the hydraulic equipment included by the modules of the kind in question, they are advantageously arranged according to one or the other of the following two ways, depending on whether the module considered is intended for hot water draw-offs or for a central heating :
  • in the first case, the equipment mounted on the pipe comprises in series a circulation pump, a non-return valve and the primary circuit of a heat exchanger,
  • in the second case, the equipment mounted on the pipe comprises a three-way valve, the said pipe constituting two of the three ways, namely a first way connected to the tubular section of hot water and a second way connected to the tubular section of water cooled, a first bypass fitted with a circulation pump, one end of which constitutes the third channel of the valve and the other end of which constitutes a hot water starting block suitable for being connected to the upstream end of a central heating pipe comprising at least one radiator, and a second branch, one end of which is connected to a point in the portion, of the above pipe, constituting the second channel of the valve and the other end of which constitutes a stud return of cooled water suitable for connection to the downstream end of the above central heating pipe.

L'invention vise également chacun des modules ci-dessus définis.The invention also relates to each of the modules defined above.

Elle comprend, mises à part ces dispositions principales, certaines autres dispositions qui s'utilisent de préférence en même temps et dont il sera plus explicitement question ci-après.It includes, apart from these main provisions, certain other provisions which are preferably used at the same time and which will be more explicitly discussed below.

Dans ce qui suit, l'on va décrire quelques modes de réalisation préférés de l'invention en se référant au dessin ci-annexé d'une manière bien entendu non limitative.In what follows, some preferred embodiments of the invention will be described with reference to the accompanying drawing in a manner which is of course not limiting.

La figure 1, de ce dessin, montre très schématiquement un module constitutif d'un circuit de chauffage ou analogue à eau chaude conforme à l'invention.Figure 1 of this drawing shows very schematically a module constituting a heating circuit or the like with hot water according to the invention.

La figure 2 est le schéma d'un tel circuit comprenant plusieurs tels modules.Figure 2 is the diagram of such a circuit comprising several such modules.

D'une façon générale, on se propose de construire un circuit destiné à distribuer les calories d'une source d'eau chaude à des fins de puisage et/ou de chauffage à l'aide de modules faciles à fabriquer en série et à monter sur place.In general, it is proposed to build a circuit intended to distribute the calories from a hot water source for drawing and / or heating purposes using modules easy to mass produce and to assemble. on the spot.

A cet effet, on fait comprendre à chaque module du genre en question :

  • deux tronçons tubulaires identiques 1 et 2 rectilignes et de relativement gros diamètre, terminés par des brides, respectivement 3,4 pour le tronçon 1 et 5,6 pour le tronçon 2,
  • une structure rigide d'entretoisement 7 interposée entre les deux tronçons 1 et 2 de manière à les assembler l'un sur l'autre avec leurs axes parallèles entre eux et les faces terminales planes de leurs brides coplanaires deux à deux comme visible sur la figure 1,
  • une conduite 8 de plus petit diamètre que les tronçons 1 et 2 propre à faire communiquer entre eux ces deux tronçons,
  • et un équipement 9 monté sur ladite conduite 8.
To this end, each module of the genre in question is made to understand:
  • two identical tubular sections 1 and 2 straight and of relatively large diameter, terminated by flanges, respectively 3.4 for section 1 and 5.6 for section 2,
  • a rigid bracing structure 7 interposed between the two sections 1 and 2 so as to assemble them one on the other with their axes parallel to each other and the flat end faces of their coplanar flanges two by two as shown in the figure 1,
  • a pipe 8 of smaller diameter than the sections 1 and 2 capable of making these two sections communicate with each other,
  • and equipment 9 mounted on said pipe 8.

Les modules M ainsi définis sont destinés à être assemblés les uns sur les autres de proche en proche, avec leurs tronçons 1 juxtaposés axialement et leurs tronçons 2 également juxtaposés axialement, les tronçons ainsi juxtaposés formant deux tubes parallèles, ainsi que visible sur la figure 2, qui s'étendent entre une source de calories 10 et un raccord terminal 11 en U.The modules M thus defined are intended to be assembled one on the other step by step, with their sections 1 juxtaposed axially and their sections 2 also juxtaposed axially, the sections thus juxtaposed forming two parallel tubes, as can be seen in FIG. 2 , which extend between a source of calories 10 and a terminal connection 11 in U.

Le "relativement gros" diamètre des tronçons 1 et 2 est avantageusement de l'ordre de 100 mm (ou 4 pouces), mais peut être très inférieur, et par exemple de l'ordre de 75,50 ou même 25 mm, en particulier pour les modules, de la boucle formée, les plus éloignés de la source de calories, les brides d'assemblage devant être bien entendu harmonisées dans tous les cas.The "relatively large" diameter of the sections 1 and 2 is advantageously of the order of 100 mm (or 4 inches), but can be much smaller, and for example of the order of 75.50 or even 25 mm, in particular for the modules, from the loop formed, the furthest from the source of calories, the assembly flanges must of course be harmonized in all cases.

La structure d'entretoisement 7 peut être constituée par des profilés, plaques, tubes, etc. Elle comprend avantageusement des moyens de réglage permettant de faire varier très légèrement la distance entre les axes des deux tronçons 1 et 2 de façon à rattraper les jeux de tolérances.The bracing structure 7 can be formed by profiles, plates, tubes, etc. It advantageously comprises adjustment means making it possible to vary the distance between the axes of the two sections 1 and 2 very slightly so as to make up for the play of tolerances.

La source de calories 10 comprend elle-même une tubulure 12 de diamètre identique à celui des tronçons 1 et 2, desservant une chaudière 13 et une pompe de circulation 14, les deux extrémités de la tubulure 12 se terminant par deux brides D et R correspondant respectivement au départ de l'eau chaude et au retour de l'eau refroidie.The heat source 10 itself comprises a tube 12 of diameter identical to that of the sections 1 and 2, serving a boiler 13 and a circulation pump 14, the two ends of the tube 12 ending by two flanges D and R corresponding respectively to the flow of hot water and the return of cooled water.

La chaudière 13 peut elle-même être constituée par un groupe d'éléments générateurs dont les différent éléments peuvent être mis en fonctionnement automatiquement en fonction des besoins, ces éléments pouvant eux-mêmes être fabriqués à la façon de modules (non représentés) mutuellement assemblables, notamment, au niveau de brides analogues à celles décrites ci-dessus.The boiler 13 can itself consist of a group of generator elements, the different elements of which can be put into operation automatically as required, these elements themselves being able to be produced in the manner of mutually assemblable modules (not shown). , in particular, at the level of flanges similar to those described above.

Chacune des deux brides D et R présente des faces terminales coplanaires et un entraxe E identique à celui qui sépare les tronçons 1 et 2 de chaque module de façon telle que les deux brides D et R puissent très facilement être raccordées sur deux brides 3 et 5 situées d'un même côté d'un quelconque module M.Each of the two flanges D and R has coplanar end faces and a center distance E identical to that which separates the sections 1 and 2 of each module so that the two flanges D and R can very easily be connected to two flanges 3 and 5 located on the same side of any module M.

Pour ce qui est du raccord 11 en U, il se termine également par deux brides 15 et 16 très facilement adaptables sur deux brides 4 et 6, d'un quelconque module M, situés du côté opposé à celui où se trouvent les deux brides 3 et 5.As for the connector 11 in U, it also ends with two flanges 15 and 16 very easily adaptable on two flanges 4 and 6, of any module M, located on the side opposite to that where the two flanges are 3 and 5.

L'ensemble des modules M forme ainsi avec le raccord 11 et la tubulure 12 une première boucle fermée de relativement gros diamètre dans laquelle le tube formé par les tronçons 1 est parcouru par l'eau chauffée par la source de calories 10 et provenant du départ D alors que le tube formé par les raccords 2 correspond au retour de l'eau refroidie vers l'extrémité amont R de ce générateur.All the modules M thus form, with the connector 11 and the tubing 12, a first closed loop of relatively large diameter in which the tube formed by the sections 1 is traversed by the water heated by the source of calories 10 and coming from the start. D while the tube formed by the fittings 2 corresponds to the return of the cooled water to the upstream end R of this generator.

Bien entendu, pour rendre possibles les mises en service ou hors service des différents modules, il convient de monter des vannes d'isolement aux extrémités amont et aval de la conduite 8. De telles vannes ont été schématisées en traits mixtes en V sur la figure 1 et non représentées sur la figure 2 dans le seul but de simplifier le dessin.Of course, to make it possible to put the different modules into service or out of service, it is advisable to mount isolation valves at the upstream and downstream ends of the pipe 8. Such valves have been shown diagrammatically in phantom in V in the figure. 1 and not shown in Figure 2 for the sole purpose of simplifying the drawing.

Pour ce qui est de l'équipement 9 monté sur la conduite 8 de chaque module M, sa constitution dépend de la destination affectée au module concerné.As for the equipment 9 mounted on the line 8 of each module M, its constitution depends on the destination assigned to the module concerned.

Dans un premier cas, illustré sur la portion de gauche de la figure 2, on suppose que le module considéré est destiné à des puisages d'eau chaude, par exemple pour la toilette et la cuisine.In a first case, illustrated on the left-hand portion of FIG. 2, it is assumed that the module considered is intended for drawing hot water, for example for the toilet and the kitchen.

Dans ce cas, l'équipement 9 comprend, montés en série sur la conduite 8, une pompe de circulation 17, un clapet anti-retour 18 orienté de façon à ne permettre ta circulation de l'eau qu'en direction du tronçon 2, et le primaire 19 d'un échangeur thermique 20.In this case, the equipment 9 comprises, mounted in series on the pipe 8, a circulation pump 17, a non-return valve 18 oriented so as to allow the circulation of water only in the direction of the section 2, and the primary 19 of a heat exchanger 20.

Le secondaire 21 de cet échangeur est agencé de façon à chauffer l'eau contenue dans un ballon 22 et destinée à des puisages d'eau chaude à l'aide de robinets 23.The secondary 21 of this exchanger is arranged so as to heat the water contained in a tank 22 and intended for drawing hot water using taps 23.

Le fonctionnement d'un tel module de "puisage" est le suivant.The operation of such a "drawing" module is as follows.

Tant que la pompe 17 est à l'arrêt, on n'observe aucun débit d'eau dans la conduite 8 et donc dans le primaire 19 de l'échangeur 20. Lorsque la température qui règne dans le ballon 22 devient insuffisante, notamment à la suite d'un puisage au niveau d'un robinet 23, la pompe 17 est mise automatiquement en fonctionnement, ce qui fait circuler l'eau chaude provenant du tronçon 1 dans le primaire 19 de l'échangeur et, de là, vers le tronçon 2 et vers l'extrémité de retour R disposée en amont de la tubulure 12 faisant partie de la source de calories.As long as the pump 17 is stopped, no water flow is observed in the pipe 8 and therefore in the primary 19 of the exchanger 20. When the temperature prevailing in the tank 22 becomes insufficient, in particular at following a drawing at a tap 23, the pump 17 is automatically put into operation, which circulates the hot water coming from the section 1 in the primary 19 of the exchanger and, from there, towards the section 2 and towards the return end R disposed upstream of the tube 12 forming part of the source of calories.

Lorsque la température de l'eau dans le ballon 22 a de nouveau dépassé un seuil considéré comme suffisant, la pompe 17 est à nouveau arrêtée.When the temperature of the water in the tank 22 has again exceeded a threshold considered to be sufficient, the pump 17 is again stopped.

Dans le second cas d'application envisagé, illustré dans la partie centrale de la figure 2, on suppose que le module est affecté à l'alimentation en calories d'une canalisation de chauffage central 24 desservant des radiateurs 25.In the second envisaged application case, illustrated in the central part of FIG. 2, it is assumed that the module is assigned to supplying calories to a central heating pipe 24 serving radiators 25.

Dans ce cas, la conduite 8 est composée de trois brins, savoir :

  • un premier brin 26 dont l'extrémié amont est branchée en 27 sur le tronçon 1 et dont l'extrémité aval définit la borne de départ d'eau chaude d destinée à être raccordée à l'extrémité amont de la canalisation 24, ledit brin étant équipé d'une vanne à trois voies 28 dont il constitue lui-même deux voies a et b et d'une pompe de circulation 29 montée de façon à entraîner l'eau vers la borne d,
  • un second brin 30 reliant une borne de retour r destinée à être raccordée à l'extrémité aval de la canalisation 24 à un point 31 de branchement sur le tronçon 2,
  • et un troisième brin de dérivation 31 dont une extrémité est raccordée en 32 au brin 30 et dont l'autre extrémité forme la troisième voie c de la vanne à trois voies 28.
In this case, line 8 is made up of three strands, know:
  • a first strand 26 whose upstream end is connected at 27 to the section 1 and whose downstream end defines the hot water start terminal d intended to be connected to the upstream end of the pipe 24, said strand being equipped with a three-way valve 28 of which it itself constitutes two ways a and b and a circulation pump 29 mounted so as to drive the water towards the terminal d,
  • a second strand 30 connecting a return terminal r intended to be connected to the downstream end of the pipe 24 at a point 31 of connection on the section 2,
  • and a third branch strand 31, one end of which is connected at 32 to strand 30 and the other end of which forms the third path c of the three-way valve 28.

Cette vanne 28 est associée à des moyens de commande permettant de relier à la voie b soit la voie a seule, soit la voie c seule, soit partiellement les deux voies a et b dans des proportions réglables, de préférence automatiquement et par exemple en fonction de la température ambiante qui règne dans les locaux à chauffer.This valve 28 is associated with control means making it possible to connect to track b either the track a alone, or the track c alone, or partially the two tracks a and b in adjustable proportions, preferably automatically and for example depending the ambient temperature prevailing in the premises to be heated.

Le fonctionnement de ce module de "chauffage" est le suivant.The operation of this "heating" module is as follows.

Lors d'une période de chauffage, la pompe 29 est mise en fonctionnement en permanence et c'est la position de la vanne à trois voies 28 qui est asservie avantageusement à la température ambiante du local chauffé par le radiateur 25, ladite vanne 28 assurant une liaison exclusive entre les deux voies a et b lorsque la température de l'eau circulant dans le radiateur 25 est insuffisante et, au contraire, une liaison exclusive entre les deux voies c et b tant que ladite température dépasse un seuil prédéterminé, toute solution intermédiaire avec envoi vers la voie b de mélanges des débits d'eau provenant des deux voies a et c pouvant être envisagée pour les températures intermédiaires.During a heating period, the pump 29 is put into continuous operation and it is the position of the three-way valve 28 which is advantageously controlled at ambient temperature of the room heated by the radiator 25, said valve 28 ensuring an exclusive connection between the two channels a and b when the temperature of the water circulating in the radiator 25 is insufficient and, on the contrary, an exclusive connection between the two channels c and b as long as said temperature exceeds a predetermined threshold, any solution intermediate with sending to channel b mixtures of water flows from of the two channels a and c which can be envisaged for the intermediate temperatures.

En suite de quoi, et quel que soit le mode de réalisation adopté, on dispose finalement de circuits de chauffage ou analogues à eau chaude dont la constitution et le fonctionnement résultent suffisamment de ce qui précède.As a result of this, and whatever the embodiment adopted, there are finally heating circuits or the like with hot water, the constitution and operation of which result sufficiently from the above.

Ces circuits présentent de nombreux avantages par rapport à ceux antérieurement connus, notamment en ce que leur conception en modules rend possibles, d'une part, une fabrication en grande série et, d'autre part, des montages sur place extrêmement simples, puisque ces montages font intervenir tout simplement l'établissement de raccords étanches au niveau des brides mutuellement juxtaposées des tronçons 1 et 2 contre les brides adjacentes comprises soit par d'autres modules, soit (D,R) par la source de calories 10, soit (15,16) par le raccord 11 en U, la boucle (1,11,2,12) ainsi formée étant ensuite complétée,

  • soit, pour chaque module de puisage, par adaptation, sur le circuit primaire (19) de ce module, du circuit secondaire (21) de l'échangeur (20) concerné,
  • soit, pour chaque module de chauffage, par branchement, sur les plots en attente (d et r) de ce module, de la canalisation de chauffage (24) concernée.
These circuits have numerous advantages compared to those previously known, in particular in that their design in modules makes possible, on the one hand, mass production and, on the other hand, extremely simple on-site assemblies, since these assemblies quite simply involve the establishment of tight connections at the level of the mutually juxtaposed flanges of the sections 1 and 2 against the adjacent flanges included either by other modules, or (D, R) by the heat source 10, or (15 , 16) by the U-shaped connector 11, the loop (1,11,2,12) thus formed then being completed,
  • either, for each drawing module, by adaptation, on the primary circuit (19) of this module, of the secondary circuit (21) of the exchanger (20) concerned,
  • or, for each heating module, by connection, on the pending pads (d and r) of this module, of the heating pipe (24) concerned.

Comme il va de soi, et comme il résulte d'ailleurs déjà de ce qui précède, l'invention ne se limite nullement à ceux de ses modes d'application et de réalisation qui ont été plus spécialement envisagés ; elle en embrasse, au contraire, toutes les variantes, notamment celles où les deux brides (D,R) du générateur de calories seraient non pas disposées à proximité d'une chaudière, comme sur le schéma de la figure 1, mais reliées aux bornes d'une telle chaudière par des conduites calorifugées pouvant s'étendre sur plusieurs étages, comme c'est le cas pour l'alimention en eau chaude (de puisage et de chauffage) d'un immeuble de plusieurs étages à partir d'un groupe générateur de calories unique.As goes without saying, and as it already follows from the above, the invention is in no way limited to those of its modes of application and embodiments which have been more especially envisaged; on the contrary, it embraces all variants, in particular those where the two flanges (D, R) of the calorie generator are not placed near a boiler, as in the diagram in FIG. 1, but connected to the terminals of such a boiler by thermally insulated pipes which can extend over several floors, as is the case for supplying hot water (drawing and heating) to a building of several floors from a group unique calorie generator.
