Abstract

A variable water volume is established to maintain the water at constant temperature, and prevent the admission of cold water if the stored water temp. is not sufficiently high. The upper surface of the tank (2) has for its upper surface (1) a piston or membrane. A solenoid valve (4) is used to control water entry into the tank, and is controlled (3) by the temp. of the water. When the water is hot the solenoid valve admits more cold water, this process continuing while heating energy is available or until the maximum tank capacity is attained. When energy is no longer available there is no more cold water admitted when hot water is drawn off. A tap (9) can be used to bypass the solenoid valve to get the system started from cold.

Description

La présente invention concerne les ballons d'eau chaude (chauffe eau, chauffe bain selon leur dénomination). Elle est intéressante principalement avec l'utilisation des énergies discontinués tel que le solaire qui sera pris comme exemple. The present invention relates to hot water tanks (water heaters, bath heaters according to their name). It is interesting mainly with the use of discontinuous energies such as solar which will be taken as an example.

Dans l'état actuel de la technique (fig. 1) un ballon d'eau (2) est chauffé grtce à un circuit primaire. Ce circuit primaire est composé d'un capteur solaire (6) et d'un échangeur de chaleur (7). Le liquide contenu dans le circuit primaire se réchauffe dans le capteur grâce au rayonnement solaire puis va se refroidir dans l'échangeur en cédant ses calories à contenue dans le ballon. In the current state of the art (fig. 1) a water tank (2) is heated by a primary circuit. This primary circuit is composed of a solar collector (6) and a heat exchanger (7). The liquid contained in the primary circuit heats up in the collector thanks to solar radiation then will cool in the exchanger by yielding its calories to contained in the balloon.

Pendant les périodes oU'l'énergie reçue par les capteurs est faible (hiver, printemps, automne) le contenu du ballon est chauffé entierement mais la température à l'intérieur du ballon ne s'élève que de quelques degrés. During periods when the energy received by the collectors is low (winter, spring, autumn) the contents of the tank are fully heated but the temperature inside the tank rises only a few degrees.

Prenons par exemple un ballon de deux cents litres dont l'eau est à 80 celoius au début d'une journée peu ensoleillée, le soir la température des deux cents litres d'eau s'élèvera par exemple à 280. Â cette température l'eau est inutilisable pour l'usage domestique ou industriel escompté. I1 serait dans ce ca" bien plus intéressant pendant cette meme journée d'obtenir oient litres d'eau à 480 ou oinquante litres à 880 (les déperditions n'étant pas prises en compte).Let us take for example a balloon of two hundred liters whose water is at 80 celoius at the start of a day with little sunshine, in the evening the temperature of the two hundred liters of water will rise for example to 280. At this temperature the water cannot be used for the intended domestic or industrial use. I1 would be in this ca "much more interesting during this same day to obtain oient liters of water at 480 or einquante liters at 880 (the losses not being taken into account).

En somme, il serait intéressant d'utiliser l'énergie reçue pour chauffer de l'eau à une température prédéterminée quitte à en obtenir une quantité limitée. D'où le procédé de ballon à volume variable. In short, it would be interesting to use the energy received to heat water to a predetermined temperature even if it means obtaining a limited quantity. Hence the variable volume balloon process.

Ce ballon devra comporter une partie mobile permettant d'augmenter ou de diminuer le volume d'eau à chauffer. This tank must have a movable part to increase or decrease the volume of water to be heated.

De nombreux procédés peuvent titre mis en oeuvre pour satisfaire cette exigence. Deux exemples seront exposés. Many methods can be used to meet this requirement. Two examples will be presented.

-A- LE BALLON A VOLU}IE VARIABLE GRACE A UNE MEBrsBRllE ELASTIQUE (fig. 2)
Le ballon est divisé par une membrane (1) qui peut se déformer sous la pression soit vers le haut et donc augmenter le volume soit vers le bas et réduire le volume jusqu'à expulsion complète de l'eau si nécessaire. Pour que cette amélioration soit viable quelques petites transformations sont nécessaire par rapport au ballon classique
a) fixer la membrane dans le ballon de manière étanche
b) réguler l'entrée d'eau en fonction de la température intérieure du ballon.Pour ce faire un aquastat, un thermostat ou un tableau de régulation(3) donne le signal à l'électrowanne (4) de s'ouvrir et de laisser entrer l'eau lorsque la température de l'eau contenue dans le ballon est supérieure à la température choisie. Dès que la température de l'eau contenue dans le ballon revient par l'apport d'eau franche inférieure a la température choisie l'électrovanne se referme et ainsi de suite. S il n'y a plus d'eau dans le ballon, la chaleur de l'eau de l'échangeur (7) déclenchera l'ouverture de l'électrovanne (4) des que la température du circuit primaire sera adéquate.-A- THE VOLUME BALLOON} VARIABLE THANKS TO AN ELASTIC MEBrsBRllE (fig. 2)
The balloon is divided by a membrane (1) which can deform under pressure either upwards and therefore increase the volume or downwards and reduce the volume until complete expulsion of the water if necessary. For this improvement to be viable some small transformations are necessary compared to the classic balloon
a) fix the membrane in the balloon tightly
b) regulate the water inlet as a function of the internal temperature of the tank. To do this, an aquastat, a thermostat or a control panel (3) gives the signal to the electro valve (4) to open and let the water enter when the temperature of the water in the tank is higher than the chosen temperature. As soon as the temperature of the water contained in the tank returns by adding fresh water below the selected temperature, the solenoid valve closes and so on. If there is no more water in the tank, the heat of the water in the exchanger (7) will trigger the opening of the solenoid valve (4) as soon as the temperature of the primary circuit is adequate.

Il serait opportun que sur l'arrivée l'eau froide dans le ballon soit fixé un système simple qui grâce à la pression permettrait de mélanger l'eau contenue dans le ballon en vue d'une homogénéisation thermique procurant une plus grande précision du système de régulation. Ce système pourrait être une sortie en pomme d'arrosoir, une sortie à ailettes, impliquant un mouvement de rotation à l'eau froide. It would be appropriate for the cold water in the tank to be fitted with a simple system which, thanks to the pressure, would make it possible to mix the water contained in the tank with a view to thermal homogenization providing greater accuracy of the regulation. This system could be a sprinkler head outlet, a fin outlet, involving a rotational movement in cold water.

c) la pression de sortie d'eau chaude peut être provoquée par
- la chute d'eau Si le ballon est situé en hauteur
- l'introduction au dessus de la membrane d'un gaz (5) par exemple de l'azote si le ballon ne peut etre situé en hauteur ou si la pression de chute est insuffisante. Le réglage de la pression de ce gaz se fera en fonction de l'installation.c) the hot water outlet pressure can be caused by
- the waterfall If the balloon is located high
- The introduction above the membrane of a gas (5), for example nitrogen if the balloon cannot be located high or if the falling pressure is insufficient. The pressure of this gas will be adjusted according to the installation.

- d) l'eau chaude sortira par le bas du ballon pour permettre d'utiliser toute l'eau. Si l'on pense nécessaire de garder une quantité d'eau en permsnence dans leballon (par exemple pour laisser l'aquastat en contact aqueux) il sera possible d'introduire en bas du ballon une grille interdisant à la membrane de se déformer complètement vers le bas et d'augmenter la hauteur de la tubulure de sortie eau chaude
e) l'échangeur de chaleur t73 sera dissimulé sur les parois du ballon pour permettre à la membrane (1) de se déformer vers le bas sans rencontrer d'obstacle.- d) hot water will come out from the bottom of the tank to allow all the water to be used. If it is deemed necessary to keep a permanent quantity of water in the balloon (for example to leave the aquastat in aqueous contact), it will be possible to introduce a grid at the bottom of the balloon preventing the membrane from deforming completely towards the bottom and increase the height of the hot water outlet tubing
e) the heat exchanger t73 will be concealed on the walls of the tank to allow the membrane (1) to deform downwards without encountering any obstacle.

-B- BALLON À VOLUKE VARIABLE GXhCE A UN PISTON OU FLOTTEUR (fig. 3 & )
Le ballon est formé de deux parties : un corps (2) et un élément mobile flotteur ou piston (1) qui sous la pression ou la dépression montera ou descendra dans le corps augmentant ou diminuant le volume du ballon. Pour que ce ballon Boit fonctionnel quelques améliorations sont nécessaires
a) l'étanchéité entre le flotteur et le corps devra titre parfaite, la technique actuelle nous donne de nombreux procédés tel que joint, segment...-B- BALLOON WITH VARIABLE VOLUKE GXhCE HAS A PISTON OR FLOAT (fig. 3 &)
The balloon is made up of two parts: a body (2) and a movable float or piston element (1) which under pressure or depression will rise or fall in the body increasing or decreasing the volume of the balloon. For this ball to drink functional some improvements are necessary
a) the seal between the float and the body will have perfect title, the current technique gives us many processes such as joint, segment ...

b) régaler l'entrée d'eau en fonction de la température intérieure du ballon. Pour ce faire un aquastat, un thermostat ou un tableau de régulation(3) donne le signal à l'électrovanne (4) de s'ouvrir lorsque la température de l'eau contenue dans le balcon est supérieure à la température choisie. Dès que la température devient, par l'apport d'eau franche, inférieure à la température choisie l'électrovanne se referme et ainsi de suite. b) adjust the water inlet according to the internal temperature of the tank. To do this, an aquastat, a thermostat or a control panel (3) gives the signal to the solenoid valve (4) to open when the temperature of the water contained in the balcony is higher than the chosen temperature. As soon as the temperature becomes, by the supply of clean water, lower than the selected temperature the solenoid valve closes and so on.

L'eau froide (10) sous pression entrant dans le ballon soulèvera le piston (1) jusqu'à la fermeture de l'électrovanne. Lorsque le piston est au plus bas de sa course il reste une garde d'eau inutilisable dans cet exemple (effet de vide), il va de soit qu'en donnant une forme concave au piston on peut diminuer cette garde d'eau dans ce cas il faudra déplacer l'échangeur ou opter pour un ballon sans circuit primaire 11 eau du ballon étant directement chauffée dans le capteur. The cold water (10) under pressure entering the balloon will raise the piston (1) until the solenoid valve closes. When the piston is at the bottom of its stroke there remains an unusable water guard in this example (vacuum effect), it goes without saying that by giving a concave shape to the piston we can reduce this water guard in this in this case, it will be necessary to move the exchanger or opt for a tank without a primary circuit 11 water from the tank being directly heated in the collector.

c) la pression de sortie d'eau chaude est effectuée par le poids du piston surmonté d'une tare (8). Cette tare permet de régler la pression en fonction de l'installation. Le poids du piston et de la tare ne devant pas être trop important pour ne pas empêcher la montée du piston sous la pression d'eau froide. c) the hot water outlet pressure is carried out by the weight of the piston surmounted by a tare (8). This tare allows the pressure to be adjusted according to the installation. The weight of the piston and the tare should not be too great to avoid preventing the piston from rising under cold water pressure.

d) prévoir un système permettant la charge de l'appareil en eau lors de sa mise en service tel que robinet de charge (9) en by-pass sur ltelectro- vanne (4) ou un aquastat réglable sur basse température,
e) à remarquer qu'un détartrage, périodique chimique ou mécanique est nécessaire pour une bonne étanchéité entre le piston et le corps.d) provide a system allowing the device to be charged with water when it is put into service, such as a charging tap (9) by bypass on the electro-valve (4) or an aquastat adjustable at low temperature,
e) note that a chemical or mechanical periodic descaling is necessary for a good seal between the piston and the body.

Au regard de ces deux exemples de ballon à volume variable, il est à remarquer les caractéristiques et les avantages de tous les ballons de ce type. With regard to these two examples of variable volume balloons, it is worth noting the characteristics and advantages of all the balloons of this type.

Ces ballons permettent d'utiliser l'énergie reçue pour chauffer une quantité d'eau certes variable mais utilisable grtGe à sa température élevée plut8t que de chauffer une grande quantité d'eau inutilisable à cause de sa basse température. These balloons allow the energy received to be used to heat a quantity of water that is certainly variable but usable grtGe at its high temperature rather than heating a large quantity of water unusable because of its low temperature.

Ils permettent d'utiliser des sources d'énergies discontinues tel que le solaire, les pompes à chaleur, le méthane par fermentation anaérobie etc... They allow the use of discontinuous energy sources such as solar, heat pumps, methane by anaerobic fermentation, etc.

pendant une période plus étendue sur l'année que dans les ballons classiques.for a longer period of the year than in classic balloons.

Dans les ballons à volume variable c'est la quantité d'eau à chauffer qui oscille en fonction de l'énergie reçue et non la température. In variable volume tanks it is the quantity of water to be heated which oscillates according to the energy received and not the temperature.

Ils permettent de ne pas refroidir l'eau chaude non utilisée par une arrivée intempestive d'eau froide comme dans le ballon classique rendant ainsi possible le stockage de cette eau chaude. They make it possible not to cool the hot water which is not used by an untimely arrival of cold water as in the conventional tank thus making possible the storage of this hot water.

Ils permettent de prendre des ballons de plus grande capacité pouvant dépasser les besoins moyens en eau chaude n'étant plus limité par le risque de ne pouvoir chauffer toute l'eau à une température convenable. They make it possible to take larger capacity tanks that can exceed the average hot water requirements, no longer being limited by the risk of not being able to heat all the water to a suitable temperature.

Ils permettent lorsque la source d'énergie est abondante un fonctionnement identique aux ballons classiques : électrovanne ouverte en permanence, élément mobileen position haute. When the energy source is abundant, they allow operation identical to conventional balloons: solenoid valve permanently open, element movable in the high position.

Ils permettent, comme dans les ballons classiques de brancher tous les appareillages et dispositifs déjà connus tels que groupe de sécurité réducteur de pression, jauge, installation en cascade ou couplée avec une énergie continue etc ... They allow, as in conventional balloons to connect all the equipment and devices already known such as pressure reducing safety group, gauge, installation in cascade or coupled with continuous energy etc ...

Ils permettent mtme avec une énergie continue tels que l'électricité, le gaz, le mazout de chauffer rapidement une petite quantité d'eau (dans l'attente d'une plus importante) à la température choisie et donc de pouvoir rapidement utiliser de l'eau chaude sans attendre le chauffage complet de toute la capacité du ballon.  They allow even with continuous energy such as electricity, gas, fuel oil to quickly heat a small amount of water (pending a larger one) to the chosen temperature and therefore to be able to quickly use l hot water without waiting for full heating of the entire capacity of the tank.
