Description

La présente invention concerne des perfectionnements et améliora­tions à des installations de chauffage central telles que celle qui est décrite et revendiquée dans le brevet français n° 86 05748 déposée le 18 avril 1986 au nom du présent demandeur.The present invention relates to improvements and improvements to central heating installations such as that which is described and claimed in French patent n ° 86 05748 filed on April 18, 1986 in the name of the present applicant.

L'installation décrite dans ce brevet comporte une chaudière, une vanne d'aiguillage à deux voies à l'extrémité de la conduite de départ d'eau de la chaudière, une première boucle alimentant un premier dispositif de chauffage à température modérée et forte inertie et une seconde boucle alimentant un second dispositif de chauffage à température plus élevée et faible inertie. Elle comporte de plus un organe de commande piloté par des moyens sensibles à la température ambiante des zones où sont installés ces dispositifs de chauffage et par des aquastats prévus sur la boucle à forte inertie et sur la conduite de sortie de la chaudière.The installation described in this patent comprises a boiler, a two-way switch valve at the end of the water supply pipe from the boiler, a first loop supplying a first heating device at moderate temperature and high inertia. and a second loop supplying a second heating device with higher temperature and low inertia. It further comprises a control member controlled by means sensitive to the ambient temperature of the areas where these heating devices are installed and by aquastats provided on the high inertia loop and on the outlet pipe of the boiler.

Au repos, la vanne d'aiguillage établit la circulation de l'eau chaude provenant de la chaudière dans la boucle à forte inertie et, lorsqu'il y a demande de la part de la boucle à faible inertie, elle commute la circulation d'eau chaude vers cette boucle, interrompant la circulation dans la boucle à forte inertie. Cette dernière n'est donc plus alimentée en eau chaude, mais, du fait de sa forte inertie, reste à une température suffisante. Cependant, si cette demande est prolongée, la boucle à forte inertie étant constituée de plusieurs éléments chauffants, il peut résulter des accumulations de chaleur dans certains de ces éléments, ce qui peut constituer un inconvénient au regard du confort de chauffe de l'installation.At rest, the switch valve establishes the circulation of hot water from the boiler in the high inertia loop and, when there is a request from the low inertia loop, it switches the circulation of hot water to this loop, interrupting circulation in the high inertia loop. The latter is therefore no longer supplied with hot water, but, because of its high inertia, remains at a sufficient temperature. However, if this request is extended, the high inertia loop being made up of several heating elements, it can result from heat accumulations in some of these elements, which can be a disadvantage with regard to the heating comfort of the installation.

Le but de la présente invention est de remédier à cet inconvénient en assurant une circulation continue dans la boucle à forte inertie indépendante de la circulation de l'eau chaude de la chaudière.The object of the present invention is to remedy this drawback by ensuring continuous circulation in the high inertia loop independent of the circulation of hot water from the boiler.

L'invention concerne donc un perfectionnement à l'installation de chauffage centrale selon l'une des revendications 1 à 4 du brevet n° 86 05748.The invention therefore relates to an improvement to the central heating installation according to one of claims 1 to 4 of patent n ° 86 05748.

Selon une autre caractéristique, une bouteille casse-pression est prévue entre la chaudière et la première boucle, cette bouteille comportant, côté chaudière, une entrée reliée à la première sortie de la vanne d'aiguillage et une sortie reliée à la conduite de retour de la chaudière et, côté boucle, une sortie reliée au collecteur d'arrivée du premier dispositif de chauffage et une entrée reliée au collecteur de retour dudit dispositif.According to another characteristic, a pressure-breaker bottle is provided between the boiler and the first loop, this bottle comprising, on the boiler side, an inlet connected to the first outlet of the switch valve and an outlet connected to the return line from the boiler and, on the loop side, an outlet connected to the inlet manifold of the first heating device and an inlet connected to the return manifold of said device.

Selon une autre caractéristique de l'invention, entre la phase et le neutre, le contact du second moyen de régulation est monté en série avec un relais à un contact de travail et deux contacts de repos, le contact de travail est monté en série avec la commande du brûleur de la chaudière et un aquastat prévu sur la seconde boucle, le premier contact de repos est monté en série avec le premier moyen de régulation, l'aquastat de la première boucle et le brûleur de la chaudière, le second contact de repos étant relié, d'une part, à la première entrée du circuit de commande de la vanne et, d'autre part, au fil de phase par l'intermédiaire du premier moyen de régulation et de l'aquastat de la première boucle, la seconde entrée étant elle-même reliée à la phase par l'intermédiaire de premier moyen de régulation et de l'aquastat de la première boucle, la troisième entrée étant reliée au neutre.According to another characteristic of the invention, between the phase and the neutral, the contact of the second regulating means is mounted in series with a relay with one working contact and two break contacts, the working contact is mounted in series with control of the boiler burner and an aquastat provided on the second loop, the first rest contact is mounted in series with the first regulating means, the aquastat of the first loop and the boiler burner, the second contact rest being connected, on the one hand, to the first input of the valve control circuit and, on the other hand, to the phase wire via the first regulating means and the aquastat of the first loop, the second input being itself connected to the phase via the first regulating means and the aquastat of the first loop, the third input being connected to the neutral.

Les caractéristiques de l'invention mentionnées ci-dessus, ainsi que d'autres, apparaîtront plus clairement à la lecture de la description suivante d'un exemple de réalisation, ladite description étant faite en relation avec les dessins joints, parmi lesquels:

De la chaudière 1, Fig. 1, sort une conduite de départ d'eau 2 munie d'un limiteur de température 3. A l'extrémité de la conduite 2, se trouve une vanne d'aiguillage 4. D'autre part, à la chaudière 1, arrive une conduite de retour d'eau 5 comportant un accélérateur 6.From boiler 1, Fig. 1, a water outlet pipe 2 with a temperature limiter 3 comes out. At the end of the pipe 2 there is a switching valve 4. On the other hand, a boiler arrives water return line 5 comprising an accelerator 6.

A une voie 4′ de la vanne 4, est reliée une première entrée 20 d'une bouteille casse-pression 21 dont une première sortie 22 est reliée à la conduite 5 de retour à la chaudière 1. A partir d'une seconde sortie 23 de la bouteille 21, est formée une première boucle 7 comportant un aquastat 8, un accélérateur 14, un collecteur 9 et, entre le collecteur 9 et un collecteur de retour 5′ relié à une seconde entrée 24 de la bouteille 21, une pluralité d'organes de chauffage tels que des planchers chauffants PC1, PC2, ..., PCn. A la Fig. 1, on n'a représenté que trois organes de chauffage PC1, PC2 et PC3. De préférence les organes PC1 à PCn sont montés en parallèle. L'ensemble des organes de chauffage PC1 à PCn comporte un moyen REG1 sensible à la température ambiante de la zone où il est installé.A channel 4 ′ of the valve 4 is connected to a first inlet 20 of a pressure relief bottle 21, a first outlet 22 of which is connected to the line 5 returning to the boiler 1. From a second outlet 23 of the bottle 21, is formed a first loop 7 comprising an aquastat 8, an accelerator 14, a collector 9 and, between the collector 9 and a return collector 5 ′ connected to a second inlet 24 of the bottle 21, a plurality of '' organs heating such as heated floors PC1, PC2, ..., PCn. In Fig. 1, only three heating elements PC1, PC2 and PC3 have been shown. Preferably the members PC1 to PCn are mounted in parallel. The set of heating elements PC1 to PCn includes a means REG1 sensitive to the ambient temperature of the zone where it is installed.

Entre l'autre voie 4˝ de la vanne 4 et un collecteur de retour 5˝ communiquant également avec la conduite 5 de retour à la chaudière 1, est prévue une seconde boucle 10 comprenant un collecteur de départ 11 et une pluralité d'organes de chauffage tels que des radiateurs R1, ..., Rn. A la Fig. 1, ces organes de chauffage sont au nombre de trois. De préférence, les radiateurs R1 à Rn sont montés en parallèle entre le collecteur 11 et le collecteur de retour 5˝. La boucle 10 comporte aussi un moyen REG2 sensible à la température ambiante de la zone où elle est installée. Entre la vanne 4 et le collecteur 11 est montée un aquastat 3′.Between the other channel 4˝ of the valve 4 and a return manifold 5˝ also communicating with the pipe 5 for return to the boiler 1, a second loop 10 is provided, comprising a flow collector 11 and a plurality of heating such as radiators R1, ..., Rn. In Fig. 1, these heating members are three in number. Preferably, the radiators R1 to Rn are mounted in parallel between the collector 11 and the return collector 5˝. The loop 10 also includes a means REG2 sensitive to the ambient temperature of the area where it is installed. Between the valve 4 and the manifold 11 is mounted an aquastat 3 ′.

La vanne 4 est, de préférence, une vanne à deux voies et à trois positions. Dans une première position, l'eau circule uniquement de la conduite 2 vers la voie 4′, dans une seconde position, uniquement vers la voie 4˝ et, dans une troisième position, vers les deux voies 4′ et 4˝ en même temps. La commande de la vanne 4 dans l'une de ces trois positions est effectuée au moyen d'un circuit 12.The valve 4 is preferably a two-way, three-position valve. In a first position, the water circulates only from line 2 to track 4 ′, in a second position, only to track 4˝ and, in a third position, to both tracks 4 ′ and 4˝ at the same time . The valve 4 is controlled in one of these three positions by means of a circuit 12.

La Fig. 2 représente le circuit qui effectue, d'une part, la commande du brûleur de la chaudière 1 et, d'autre part, la commande de la vanne 4. Le contact du moyen REG2 est monté en série avec un relais K entre le fil de neutre N et le fil de phase P. Le relais K a un contact de travail K1 et deux contacts de repos K2 et K3. Avec le contact K1, sont montés en série entre les fils N et P le contact de l'aquastat 3′ de la boucle 10 et la commande du brûleur 13. Avec la commande 13, sont également montés en série entre les fils P et N, d'une part, un ensemble constitué du contact du moyen REG1 et celui de l'aquastat 8 montés en série et, d'autre part, le contact de repos K2. Au point commun entre le contact K2 et l'ensemble des contacts 8, REG1, est relié une première entrée 12′ du circuit 12 de commande de la vanne 4 et, par l'intermédiaire du contact de repos K3, une seconde entrée 12˝ du circuit 12. Ce dernier comporte une troisième entrée 12‴ reliée au fil neutre N pour son alimentation.Fig. 2 represents the circuit which performs, on the one hand, the control of the burner of the boiler 1 and, on the other hand, the control of the valve 4. The contact of the means REG2 is mounted in series with a relay K between the wire neutral N and the phase wire P. Relay K has a working contact K1 and two break contacts K2 and K3. With the contact K1, are mounted in series between the wires N and P the contact of the aquastat 3 ′ of the loop 10 and the burner control 13. With the control 13, are also mounted in series between the wires P and N , on the one hand, an assembly consisting of the contact of the means REG1 and that of the aquastat 8 connected in series and, on the other hand, the rest contact K2.

The latter has a third input 12 ‴ connected to the neutral wire N for its supply.

Lorsque les entrées 12′ et 12˝ du circuit 12 sont isolées, la vanne est au repos dans la seconde position. L'eau de la chaudière est uniquement dirigée vers la boucle 10. Lorsqu'entre l'entrée 12′ et l'entrée 12‴ est présent une tension égale à celle entre le fil P et le fil N, l'entrée 12˝ étant isolée, le circuit 12 effectue la commande de la vanne 4 pour ouvrir la voie 4′ et l'eau de la chaudière 1 circule dans les deux boucles 7 et 10. Lorsque seule l'entrée 12˝ reçoit un potentiel égal à celui du fil P, le circuit 12 effectue la commande de la vanne pour fermer la voie 4˝ et l'eau ne peut circuler dans aucune des deux boucles 7 et 10. Dans la pratique, comme on le comprend à la lecture de la fig. 2, ce cas ne peut avoir lieu. Enfin, lorsque les deux entrées 12′ et 12˝ sont au potentiel du fil P, la voie 4′ est ouverte et la voie 4˝ est fermée. L'eau de la chaudière circule alors dans la seule boucle 7.When the inputs 12 ′ and 12˝ of circuit 12 are isolated, the valve is at rest in the second position. The water from the boiler is only directed towards the loop 10. When there is a voltage between input 12 ′ and input 12 ‴ equal to that between wire P and wire N, input 12˝ being isolated, the circuit 12 performs the control of the valve 4 to open the channel 4 ′ and the water from the boiler 1 circulates in the two loops 7 and 10. When only the input 12˝ receives a potential equal to that of the wire P, the circuit 12 performs the control of the valve to close the channel 4˝ and the water cannot circulate in either of the two loops 7 and 10. In practice, as can be understood on reading fig. 2, this case cannot take place. Finally, when the two inputs 12 ′ and 12˝ are at the potential of the wire P, the channel 4 ′ is open and the channel 4˝ is closed. The boiler water then circulates in the only loop 7.

L'installation selon l'invention fonctionne comme suit. Quand il n'y a pas de demande de la part de la boucle 10, le contact du moyen de régulation REG2 est ouvert. Le relais n'est donc pas alimenté. Le contact K1 est ouvert et les contacts K2 et K3 sont fermés. S'il n'y a pas non plus de demande de la part de la boucle 7, le contact du moyen REG1 est ouvert. La commande 13 et le circuit 12 ne sont pas activés. Ainsi, la vanne 4 est au repos et l'eau circule uniquement dans la boucle 10 et les éléments de chauffage R1 à Rn.The installation according to the invention operates as follows. When there is no request from loop 10, the contact of the regulating means REG2 is open. The relay is therefore not supplied. Contact K1 is open and contacts K2 and K3 are closed. If there is also no request from the loop 7, the contact of the means REG1 is open. The control 13 and the circuit 12 are not activated. Thus, the valve 4 is at rest and the water circulates only in the loop 10 and the heating elements R1 to Rn.

Si la température ambiante dans la zone où sont installés les organes de chauffage PC1 à PCn et celle de l'eau dans ces organes sont inférieures à des températures de consigne données, les contacts du moyen REG1 et de l'aquastat 8 sont fermés. Les contacts K2 et K3 étant fermés, la commande du brûleur 13 est activée. Les entrées 12′ et 12˝ sont au potentiel du fil P et la vanne 4 est dans la première position, c'est-à-dire ouverte sur la voie 4′ et fermée sur la voie 4˝. L'eau de la chaudière circule donc dans la bouteille 21 où elle échange sa chaleur avec l'eau qui, elle, circule, au moyen de l'accélérateur 14, dans la boucle 7. La température de l'eau dans la boucle 7 est limitée à une température de consigne donnée par l'aquastat 8 qui commande le brûleur 13.If the ambient temperature in the zone where the heating elements PC1 to PCn are installed and that of the water in these elements are lower than given set temperatures, the contacts of the means REG1 and of the aquastat 8 are closed. The contacts K2 and K3 being closed, the control of the burner 13 is activated. The inputs 12 ′ and 12˝ are at the potential of the wire P and the valve 4 is in the first position, that is to say open on channel 4 ′ and closed on channel 4˝. The water from the boiler therefore circulates in the bottle 21 where it exchanges its heat with the water which itself circulates, by means of the accelerator 14, in the loop 7. The temperature of the water in the loop 7 is limited to a set temperature given by the aquastat 8 which controls the burner 13.

Si, en outre, la température ambiante de la zone où sont installés les organes de chauffage R1 à Rn est inférieure à une température donnée de consigne, le contact du moyen REG2 est fermé et le relais K est alimenté. Les contacts K2 et K3 sont ouverts et le contact K1 est fermé. L'entrée 12′ est toujours alimentée, mais plus l'entrée 12˝. La vanne 4 se trouve donc dans sa troisième position dans laquelle elle est ouverte à la fois sur la voie 4′ et le voie 4˝. L'eau circule à la fois dans la boucle 7 et la bouteille 21 et la boucle 7. La commande du brûleur 13 est coupée, à moins que la température de l'eau dans la boucle 10 soit inférieure à une température de consigne donnée. Dans ce cas, le contact de l'aquastat 3′ est fermé, ce qui active la commande 13.If, in addition, the ambient temperature of the area where the heating elements R1 to Rn are installed is lower than one given set temperature, the contact of the means REG2 is closed and the relay K is energized. Contacts K2 and K3 are open and contact K1 is closed. Input 12 ′ is always supplied, but more input 12˝. The valve 4 is therefore in its third position in which it is open both on track 4 ′ and track 4˝. The water circulates at the same time in the loop 7 and the bottle 21 and the loop 7. The control of the burner 13 is cut off, unless the temperature of the water in the loop 10 is lower than a given set temperature. In this case, the contact of the aquastat 3 ′ is closed, which activates the command 13.

S'il n'y a demande que de la part de la zone où sont installés les organes chauffants R1 à Rn, le contact du moyen REG2 est fermé et le relais K est alimenté. Le contact K1 est fermé et les contacts K2 et K3 sont ouverts. Les entrées 12′ et 12˝ ne sont donc pas alimentées et la vanne 4 est au repos dans la seconde position. La voie 4′ est fermée alors que la voie 4˝ est ouverte. L'eau circule donc dans la seule boucle 10. Au cas où la température de l'eau dans la boucle 10 est inférieure à une température de consigne donnée, le contact de l'aquastat 3′ se ferme et la commande 13 est activée. Sinon, le contact de l'aquastat 3′ est ouvert et la commande du brûleur 13 n'est pas activée.If there is a request only from the zone where the heating elements R1 to Rn are installed, the contact of the means REG2 is closed and the relay K is energized. Contact K1 is closed and contacts K2 and K3 are open. The inputs 12 ′ and 12˝ are therefore not supplied and the valve 4 is at rest in the second position. Track 4 ′ is closed while track 4˝ is open. The water therefore circulates in the only loop 10. In the event that the water temperature in the loop 10 is lower than a given set temperature, the contact of the aquastat 3 ′ closes and the control 13 is activated. Otherwise, the contact of the aquastat 3 ′ is open and the control of the burner 13 is not activated.

On remarquera que, du fait de la présence du circulateur 14, l'eau dans la boucle 10 circule toujours. La bouteille 21 sert à casser la pression de circulation dans cette boucle, aussi bien lorsque l'eau circule que losqu'elle ne circule pas de la vanne 4 à la conduite de retour 5. La bouteille sert également d'échangeur entre l'eau de la chaudière et celle de la boucle 7.It will be noted that, due to the presence of the circulator 14, the water in the loop 10 still circulates. The bottle 21 serves to break the circulation pressure in this loop, both when the water circulates and when it does not circulate from the valve 4 to the return line 5. The bottle also serves as an exchanger between the water of the boiler and that of the loop 7.

L'utilisation d'une vanne à trois positions permet de résoudre les conflits qui résultent de demandes simultanées de la part des deux boucles 7 et 10. Dans ce cas, en effet, l'eau circule dans les deux boucles et le brûleur de la chaudière est en route, sauf, lorsque la température de l'eau dans la boucle 10 est déjà supérieure à sa température de consigne.The use of a three-position valve makes it possible to resolve conflicts which result from simultaneous requests from the two loops 7 and 10. In this case, in fact, water circulates in the two loops and the burner of the boiler is on, except when the water temperature in loop 10 is already higher than its set temperature.

Selon une forme de réalisation de l'invention, le circuit de commande représenté à la Fig. 2 est piloté par un microprocesseur qui reçoit les signaux des contacts des moyens de régulation REG1, REG2 et des aquastat 3′, 8 et qui pilote la commande du brûleur 13 et celle de la vanne à trois positions 4.According to one embodiment of the invention, the control circuit shown in FIG. 2 is controlled by a microprocessor which receives the signals from the contacts of the regulating means REG1, REG2 and the aquastats 3 ′, 8 and which controls the control of the burner 13 and that of the three-position valve 4.
