Abstract

The system has a reversible electric pump (13) circulating water or fluid internally in a direction (17) by passing hot water/fluid till an internal point (26) close to a user, without leaving the water to an environment, when thermostatic valves (9, 10) are closed. The pump circulates the water/fluid internally in a direction (18) for reintroducing the water/fluid contained in tubes (7, 8) into a tank (5) when the valves are closed in a reversible condition. An electronic system (14) has sensors (12, 19, 24) to detect temperature of water.

Description

OBJET DE L'INVENTIONOBJECT OF THE INVENTION

Le présent mémoire descriptif se réfère à une demande de Brevet d'Invention relatif a un seul système qui détient les deux particularités différentes :

  • Economie totale de l'eau qui, normalement se rejette à l'égout quand on ouvre le robinet d'eau chaude, et on attend l'arrivée de l'eau à la température désirée.
  • Economie de la plus grande partie de l'énergie calorique consommée pour chauffer l'eau qu'on laisse dans le tuyau qui apporte le fluide, depuis le chauffe-eau jusqu'à l'utilisateur, lorsque ce dernier a fini l'utilisation.
This specification refers to a Single Invention patent application which holds the two different features:
  • Total economy of the water which normally discharges to the sewer when the hot water tap is opened, and the arrival of the water at the desired temperature is awaited.
  • Saving most of the caloric energy consumed to heat the water that is left in the pipe that brings the fluid from the water heater to the user when the user has finished using it.

SECTEUR DE L'INVENTIONSECTOR OF THE INVENTION

L'invention se situe dans le secteur technique de plomberie, ou installation hydraulique dans les lieux d'habitation, appartements, maisons, industries, locaux sociaux, locaux publics et administrations.The invention is in the technical plumbing sector, or hydraulic installation in residential areas, apartments, houses, industries, social premises, public premises and administrations.

ETAT DE LA TECHNIQUESTATE OF THE ART

Les métiers de l'installation de tuyaux de distribution d'eau ne tiennent généralement pas en compte la perte d'eau et d'énergie que le client consent dans les premiers moments de chaque service, pendant l'usage de l'eau chaude. Il s'agit de deux gaspillages différents qui peuvent être contrôlés en grande partie, grâce à l'application du système décrit dans cette demande.

  • Au moment de faire usage de l'eau chaude, l'utilisateur ouvre le robinet d'eau chaude, et se dispose à attendre que l'eau servie soit à la température désirée. Pendant cette attente, un volume d'eau supérieur au volume contenu dans le tuyau qui va du chauffe-eau jusqu'au robinet, est rejeté à l'égout.
  • Quand l'utilisateur a fini sa consommation d'eau désirée, le tuyau qui va du chauffe-eau jusqu'au robinet se trouve plein d'eau à température maximale. Si persone ne fait plus usage de l'eau chaude pendant un long moment, l'eau refroidit naturellement, et par conséquent, l'énergie nécessaire au chauffage de cette eau, est perdue.
The jobs of the installation of pipes of water distribution do not generally take into account the loss of water and energy that the customer consents in the first moments of each service, during the use of hot water. These are two different wastes that can be largely controlled through the application of the system described in this application.
  • When using hot water, the user opens the hot water faucet, and is prepared to wait until the water served is at the desired temperature. During this wait, a volume of water greater than the volume contained in the pipe that goes from the water heater to the tap, is rejected in the sewer.
  • When the user has finished their desired water consumption, the pipe that goes from the water heater to the tap is full of water at maximum temperature. If persone no longer uses hot water for a long time, the water naturally cools, and as a result, the energy needed to heat this water is lost.

Ce gaspillage n'a pas été considéré jusqu'à aujourd'hui. Il peut représenter quelques dizaines de litres par jour, surtout dans les lieux d'habitation grands, où le système de chauffage de l'eau est très loin du point de consommation.This waste has not been considered until today. It can represent a few tens of liters a day, especially in large living places, where the water heating system is very far from the point of consumption.

ANTECEDENTS DE L'INVENTIONANTECEDENTS OF THE INVENTION

Le sollicitant n'a aucune information sur des systèmes usés pour l'économie de l'eau qui se rejette initialement en attendant que l'eau arrive à la température souhaitée après ouverture du robinet.The applicant has no information on used systems for saving water that is rejected initially until the water reaches the desired temperature after opening the tap.

Dans les grands ensembles comme les hôtels ou grands immeubles à distribution collective, est utilisé un système de rapprochement de l'eau chaude distribuée, du point d'usage. Il s'agit d'un conduit en circuit fermé, isolé thermiquement, dans lequel on établit un courant d'eau qui passe par la chaudière. Tout le tuyau se trouve donc en permanence à haute température, et celui-ci passe près des points de consommation. Quand on fait usage de l'eau chaude le gaspillage d'eau n'est pas important.In large complexes such as hotels or large buildings with collective distribution, is used a system of approximation of distributed hot water, the point of use. It is a thermally insulated, closed circuit conduit in which a stream of water passes through the boiler. All the pipe is thus permanently at high temperature, and this passes near the points of consumption. When using hot water the waste of water is not important.

A fin de situer l'invention, nous décrirons le système de chauffage et usage de l'eau chaude dans une installation unifamiliale.In order to situate the invention, we will describe the heating system and use of hot water in a single-family installation.

En figure 1 nous pouvons voir un système traditionnel de chauffage et utilisation au moyen d'un accumulateur électrique (cumulus). En (1) l'entrée d'eau servie par le fournisseur se divise en (2), en deux voies : la première est constituée par le système de chauffage (4), accumulation (5) et utilisation (7), et la deuxième constituée par le tuyau d'utilisation d'eau froide (8).In figure 1 we can see a traditional system of heating and use by means of an electric accumulator (cumulus). In (1) the water supply supplied by the supplier is divided into (2), in two ways: the first consists of the heating system (4), accumulation (5) and use (7), and the second constituted by the cold water use pipe (8).

Le réservoir (5) est plein d'eau chaude, ou en cours de chauffage. La valve anti retour (3) empêchera l'eau chaude contenue dans le réservoir, de reculer et revenir vers le fournisseur, ou bien de sortir par le tuyau d'eau froide, dans certains cas d'anomalies de fonctionnement.The tank (5) is full of hot water, or during heating. The anti-return valve (3) will prevent the hot water contained in the tank, back and return to the supplier, or out through the cold water pipe, in some cases of malfunctions.

En ouvrant le robinet (10), l'eau froide servie par le fournisseur pénètre dans le réservoir (5), pendant que la même quantité d'eau chaude sort par (6). L'utilisateur doit attendre en (25), que l'eau qui coule soit chaude. En ouvrant le robinet (9), on n'utilise pas le circuit de chauffage, et on obtient de l'eau froide en (25), par le conduit (8).By opening the valve (10), the cold water supplied by the supplier enters the tank (5), while the same quantity of hot water leaves (6). The user must wait in (25), that the flowing water is hot. By opening the valve (9), the heating circuit is not used, and cold water is obtained (25) through the conduit (8).

Dans le cas de chauffage de l'eau par un combustible, avec réserve d'eau chaude, le système figure 2 , est très semblable, et l'explication est la même.In the case of heating water with fuel, with hot water reserve, the system figure 2 , is very similar, and the explanation is the same.

Dans le cas d'utilisation d'un système de chauffage sans accumulation d'eau chaude, on considère que l'eau est chauffée instantanément, et une fois l'écoulement s'arrête, il reste très peu d'eau chaude dans le chauffe-eau. Le système de fonctionnement est presque identique :

  • En figure 3 nous pouvons voir un système traditionnel de chauffage d'eau et utilisation au moyen d'une chaudière à combustion, sans accumulateur d'eau chaude. Le fonctionnement est le même que dans la figure 2 , sans l'accumulateur (5).
In the case of using a heating system without accumulation of hot water, it is considered that the water is heated instantly, and once the flow stops, there is very little hot water in the heater -water. The operating system is almost identical:
  • In figure 3 we can see a traditional system of water heating and use by means of a combustion boiler, without accumulator of hot water. The operation is the same as in the figure 2 , without the accumulator (5).

DESCRIPTION DE L'INVENTIONDESCRIPTION OF THE INVENTION

En figure 4 nous expliquons le système avec chauffage de l'eau avec résistance électrique, et en figure 5 avec chauffage à combustion. Les deux systèmes possèdent une réserve ou accumulation d'eau chaude. En figure 6 nous expliquons le système avec chauffage à combustion et sans réserve d'eau chaude.In figure 4 we explain the system with water heating with electrical resistance, and in figure 5 with combustion heater. Both systems have a reserve or accumulation of hot water. In figure 6 we explain the system with combustion heating and no reserve of hot water.

La présente invention propose d'installer une pompe électrique réversible (13), un réservoir additionnel isolé thermiquement (11) et un système électronique (14) comprenant plusieurs capteurs (12) (19) (24) qui permettront de connaitre la température de l'eau en divers points, et le capteur (20) qui permettra de savoir s'il existe un mouvement d'eau dans le tuyau.The present invention proposes to install a reversible electric pump (13), an additional thermally insulated tank (11) and an electronic system (14) comprising several sensors (12) (19) (24) which will make it possible to know the temperature of the tank. water at various points, and the sensor (20) which will make it possible to know if there is a movement of water in the pipe.

Pendant l'installation, la valve anti retour (3)(figures 1-2-3) qui est installée par certains fabricants à l'entrée du réservoir d'eau chaude sera déplacé en (3)(figures 4-5-6), afin d'intéresser toute l'installation de l'habitation, permettant ainsi que le liquide puisse circuler dans les deux directions dans le réservoir (5).During installation, the anti-return valve (3) ( Figures 1-2-3 ) that is installed by some manufacturers at the entrance to the hot water tank will be moved to (3) ( Figures 4-5-6 ), to interest the entire installation of the house, allowing the liquid to flow in both directions in the tank (5).

• Phase 1: début de l'utilisation de l'eau chaude • Phase 1: start of hot water use

Le futur utilisateur de l'eau chaude, n'ouvre pas le robinet directement mais il effectue la commande électronique (15) située dans le système électronique (14). Le système électronique (14) met en mouvement la pompe (13) de manière à établir une circulation interne d'eau dans la direction (17), sans aucune sortie d'eau à l'extérieur, et par conséquent sans gaspillage d'eau. L'eau à température ambiante, contenue dans les conduits, entrera dans le réservoir (5). L'eau chaude sortira par la sortie (6) du réservoir (5) et avancera progressivement par le conduit (7) jusqu'au détecteur (19). Ce détecteur (19) permettra au système électronique (14) de connaitre l'arrivée de l'eau chaude et d'arrêter le fonctionnement de la pompe (13), arrêtant ainsi la circulation interne de l'eau. Le système électronique (14) avertira l'utilisateur moyennant des signaux lumineux ou acoustiques, que l'eau chaude se trouve à sa disposition.The future user of the hot water, does not open the tap directly but it makes the electronic control (15) located in the electronic system (14). The electronic system (14) sets the pump (13) in motion so as to establish an internal circulation of water in the direction (17), without any outflow of water, and therefore without wasting water . The water at room temperature, contained in the ducts, will enter the tank (5). The hot water will exit through the outlet (6) of the tank (5) and progressively advance through the conduit (7) to the detector (19). This detector (19) will allow the electronic system (14) to know the arrival of hot water and stop the operation of the pump (13), thereby stopping the internal circulation of water. The electronic system (14) will warn the user by means of light or acoustic signals, that the hot water is at his disposal.

• Phase 2: usage continu• Phase 2: continuous use

L'utilisateur fera usage de l'eau normalement, en ouvrant à volonté les robinets (9)(10), en obtenant en (25) l'eau à la température désirée, sans aucune différence par rapport à l'usage avec une installation sans ce système d'économie. Une fois terminé l'usage de l'eau, l'utilisateur fermera les robinets (9)(10), de l'eau chaude et froide.The user will make use of the water normally, by opening at will the taps (9) (10), obtaining in (25) the water at the desired temperature, without any difference compared to the use with an installation without this system of economy. Once the use of water is finished, the user will turn off the faucets (9) (10), hot and cold water.

• Phase 3: après utilisation avec deux possibiltés• Phase 3: after use with two possibilties Possibilité première:First opportunity:

L'utilisateur active la commande (16) du système électronique (14) grâce à laquelle le système électronique met en marche la pompe à eau (13) dans le sens inverse à l'initial, établissant ainsi une circulation d'eau dans la direction (18), qui retirera l'eau chaude du tuyau, pour la stocker dans le réservoir, sans aucune perte d'eau, et avec la finalité de ne pas perdre l'énergie calorique qui restera dans le réservoir accumulateur (5). La réserve d'eau (11), qui peut être constituée par un morceau de tube isolé thermiquement (21), de section supérieure au conduit normal de l'installation, a pour fonction d'accumuler l'eau légèrement chaude qui sortira du réservoir (5) pendant cette phase. L'eau qui sort par la partie basse de ce réservoir est en phase de chauffage, ce qui fait que l'énergie calorique qui se transfère au réservoir additionnel (11) est petite, et ne se perdra pas si l'isolement de ce réservoir est soigné. Le réservoir (5) peut être fabriqué pour que le volume d'eau qui ressort du réservoir dans la direction (18), n'ait pas été chauffé pendant le procès d'utilisation normale, et par conséquent le réservoir additionnel (11) ne sera pas nécessaire. De toute façon la perte d'énergie calorique pendant cette opération de recul est minimale.The user activates the control (16) of the electronic system (14) by which the electronic system switches on the water pump (13) in the reverse direction to the initial, thus establishing a flow of water in the direction (18), which will remove hot water from the pipe, to store it in the tank, without any loss of water, and with the purpose of not not lose the caloric energy that will remain in the accumulator tank (5). The water reserve (11), which may be constituted by a thermally insulated tube piece (21) of upper section to the normal conduit of the installation, has the function of accumulating the slightly hot water that will come out of the tank (5) during this phase. The water that comes out of the lower part of the tank is in the heating phase, so that the heat energy that is transferred to the additional tank (11) is small, and will not be lost if the isolation of this tank is neat. The reservoir (5) can be made so that the volume of water that escapes from the reservoir in the direction (18) has not been heated during the normal use process, and therefore the additional reservoir (11) will not be necessary. In any case the loss of caloric energy during this recoil operation is minimal.

Possibilité deuxième:Second possibility:

L'utilisateur ne désire pas ou bien ne se souvient pas d'effectuer la commande (16), ce qui provoquerait la perte de l'énergie calorique dans le tube (7). Le système électronique (14), de manière automatique, temporisée, provoquera la mise en marche de la pompe (13) après un temps ajustable, ou quand il a détecté que la température de l'eau est en train de diminuer, ou bien quand il a détecté grâce au capteur de flux (20), que l'eau n'est pas utilisée depuis un temps ajustable.
Cette mise en marche automatique établira un flux dans la direction (18), comme il est décrit dans la possibilité première.The user does not wish or does not remember to perform the command (16), which would cause the loss of heat energy in the tube (7). The electronic system (14), automatically timed, will cause the pump (13) to turn on after an adjustable time, or when it has detected that the water temperature is decreasing, or when it has detected thanks to the flow sensor (20) that the water has not been used for an adjustable time.
This automatic start will establish a flow in the direction (18), as described in the first possibility.

Ce flux d'eau destiné à l'économie thermique s'arrêtera automatiquement grâce au système électronique (14), s'arrêtera automatiquement quand il détectera que la température au détecteur (12) se trouve proche de la température au détecteur (19), ou bien moyennant un temporisateur qui peut être inclus dans le même système électronique. Ce temporisateur peut être à temps ajustable ou intelligent. Il peut mesurer et retenir le temps utilisé pour faire arriver l'eau chaude dans la phase 1 , et faire fonctionner la pompe en sens inverse pendant le même temps.This flow of water intended for thermal economy will stop automatically thanks to the electronic system (14), will stop automatically when it detects that the temperature at the detector (12) is close to the temperature at the detector (19), or with a timer that can be included in the same electronic system. This timer can be adjustable or smart. It can measure and retain the time used to bring warm water into phase 1 , and run the pump in reverse for the same time.

With the cold water valve closed, and with the operating modulation of the pump (13) controlled by the electronic system (14), a desired and stable water temperature is obtained in the hot water outlet (10). The temperature can be adjusted by means of a potentiometer located in the electronic system (14), available to the user. Système selon la revendication 1, caractérisé par l'utilisation de vannes électriques au lieu des robinets (9) et (10), ou en plus de ceux-ci, commandés par le système électronique (14), pour ne pas permettre l'utilisation d'eau avant qu'elle n'arrive à la température correcte à son point final. La finalité est l'économie dans les lieux de fréquentation publique ou dans les cas de mauvais usage systématique, comme par exemple ouvrir souvent le robinet d'eau chaude pour une petite utilisation, et ne pas attendre l'arrivée de l'eau chaude. Dans ces cas l'eau est chauffée et elle n'arrive pas aux mains de l'utilisateur.System according to claim 1, characterized by the use of electric valves instead of or in addition to valves (9) and (10), controlled by the electronic system (14), to prevent the use of of water before it reaches the correct temperature at its end point. The purpose is economy in public places or in cases of systematic misuse, such as often open the hot water faucet for a small use, and not wait for the arrival of hot water. In these cases the water is heated and it does not reach the user's hands. Système selon la revendication 1, caractérisé par l'utilisation du système électronique (14), et le détecteur (20) pour mesurer le temps nécessaire depuis que la pompe se met en marche dans la direction (17), jusqu'à ce que l'eau chaude arrive au point (26) ; une fois finalisée l'utilisation de l'eau chaude, la pompe (13) sera mise en marche en sens contraire, dans la direction (18) pendant le temps mesuré, de façon à retourner l'eau chaude contenue dans le tube (7) au réservoir (5). Dans ce cas on n'a besoin que d'un détecteur de température, ce qui simplifie l'installation.System according to claim 1, characterized by the use of the electronic system (14), and the detector (20) for measuring the time required since the pump starts in the direction (17), until the hot water arrives at point (26); once the use of hot water has been completed, the pump (13) will be turned on in the opposite direction, in the direction (18) during the measured time, so as to return the hot water contained in the tube (7). ) to the tank (5). In this case only a temperature sensor is needed, which simplifies the installation.
