La présente invention est liée à la conception du ballon électrosolaire ainsi qu'à la commande des résistances électriques d'appoint, dans l'objectif de réduire les capacités de stockage, tout en maintenant des conditions de confort dans le respect du label Promotelec. The present invention is related to the design of the electrosolar balloon and the control of the auxiliary electrical resistances, with the aim of reducing the storage capacity, while maintaining comfort conditions in compliance with the Promotelec label.
Description de la commande de la charge de nos ballons électrosolaires: Partant du constat que: É La résistance électrique ne doit pas être placée en dessous du milieu de la hauteur du ballon électro-solaire sous peine d'altérer de façon 10 importante la production d'énergie solaire, É Que le volume du ballon doit être minimisé pour limiter l'encombrement (mise en place dans un placard 600 x 600 mm2 notamment) et les déperditions thermiques, É Que la résistance électrique doit être alimentée uniquement en 15 heures creuses, sauf cas exceptionnels, où elle est autorisée à fonctionner deux heures par jour en heures pleines, É Qu'il convient de privilégier au maximum l'utilisation de l'énergie solaire et de ne recourir à l'appoint que lorsque l'énergie solaire est insuffisante, Notre commande de charge innovante consiste à : É Limiter la capacité du ballon, en la réduisant de 100 litres au moins dans le cas des maisons individuelles, É Intégrer deux résistances électriques dont l'une est placée approximativement au milieu de la hauteur et l'autre approximativement 25 au 3/4 de la hauteur, en partant du bas du ballon, É Intégrer un système de commande qui assure le fonctionnement des deux résistances électriques en fonction de la température du ballon aux différents moments de la journée, mais aussi en fonction du signal tarifaire délivré par le réseau, et de températures de consigne qui peuvent être différentes en fonction de la résistance considérée et de la présence ou non du signal tarifaire. Description of the charge control of our electrosolar balloons: Based on the observation that: • The electrical resistance must not be placed below the middle of the height of the electro-solar balloon, otherwise the output of the balloon will be significantly altered. solar energy, É That the volume of the balloon must be minimized to limit the bulk (placing in a closet 600 x 600 mm2 in particular) and the heat losses, é That the electrical resistance must be powered only in 15 hours, except in exceptional cases, where it is allowed to operate for two hours a day during peak hours, E That the use of solar energy should be maximized, and that backup should be used only when solar energy is Insufficient, Our innovative load control is to: E Limit the capacity of the balloon, reducing it by at least 100 liters for single-family homes, É Incorporate two resis one of which is placed approximately at the middle of the height and the other approximately 3/4 of the height, starting from the bottom of the balloon, E Integrating a control system which ensures the operation of the two electrical resistances in depending on the temperature of the balloon at different times of the day, but also according to the tariff signal delivered by the network, and setpoint temperatures that may be different depending on the resistance considered and the presence or absence of the tariff signal.

Exemple:Example:
Dans cet exemple, nous utilisons le référentiel Promotelec pour un logement de 5 pièces et plus. In this example, we use the Promotelec repository for a dwelling of 5 rooms or more.
Pour obtenir le label Promotelec, le volume d'eau à 40 C à partir 5 d'une eau froide à 15 C, doit être de 450 litres/jour en catégorie A et de 540litres/jour en catégorie B. Volume Volume Temp de Q40 Ballon Appoint Consigne 500 250 60 450 400 200 71.25 450 600 300 60 540 400 200 82.5 540 Comme on le voit dans le tableau ci-dessus, l'utilisation d'un ballon de 400 litres est difficile à envisager car les niveaux de température de stockage sont très élevés entraînant des déperditions thermiques importantes ainsi que des risques d'entartrage important. To obtain the Promotelec label, the volume of water at 40 C from cold water at 15 C must be 450 liters / day in category A and 540 liters / day in category B. Volume Volume Temp of Q40 Booster Ball Setpoint 500 250 60 450 400 200 71.25 450 600 300 60 540 400 200 82.5 540 As can be seen in the table above, the use of a 400 liter flask is difficult to envisage because the temperature levels of storage are very high resulting in significant heat losses and significant risk of scaling.
En contrepartie, l'utilisation de ballon de 500 ou 600 litres est largement pénalisante en termes d'encombrement. In return, the use of 500 or 600 liter balloon is largely penalizing in terms of size.
Selon une première caractéristique: Notre régulateur de charge permet de n'utiliser qu'un ballon de 400 litres, tout en palliant les niveaux de température trop élevés décrits ci-dessus: le schéma de l'équipement de notre ballon électro-solaire est indiqué Fig. 1: É La résistance Rh permet de réchauffer le '/4 du volume supérieur, É La résistance Rb permet de réchauffer ladu volume supérieur, É Les deux résistances sont mises en service en fonction du signal tarifaire, de la température située à proximité de la résistance concernée (Th et Tb), de la température de consigne affectée à ces deux températures (Thconsn, Thconsj, Tbconsn, Tbconsj) qui peuvent être différentes selon le signal tarifaire, et de la température en bas du ballon électro-solaire. 15 25 According to a first characteristic: Our charge regulator makes it possible to use only one balloon of 400 liters, while palliating the too high temperature levels described above: the diagram of the equipment of our electro-solar balloon is indicated Fig. 1: É The resistor Rh allows to heat up the '/ 4 of the higher volume, É The resistor Rb allows to warm up the higher volume, É The two resistors are put into service according to the tariff signal, the temperature located near the concerned resistance (Th and Tb), the set temperature assigned to these two temperatures (Thconsn, Thconsj, Tbconsn, Tbconsj) that may be different depending on the tariff signal, and the temperature at the bottom of the electro-solar balloon. 15 25
2891352 -3- Scénario 1 Dans l'hypothèse de la catégorie A, on pourra envisager le scénario suivant: Rh = 1500 W (résistance électrique haute) Rb = 1500 W (résistance électrique basse) Thconsn = 65 C (thermostat haut réglé en consigne nuit) Thconsj = 40 C (thermostat haut réglé en consigne jour) Tbconsn = 55 C (thermostat haut réglé en consigne nuit) Tbconsj: non utilisée. (thermostat bas réglé en consigne jour) En partant de l'hypothèse que la totalité du ballon est à 15 C, lors de la relance diurne de 2 heures, Rh va être mis en service de 17h à 19h fournissant ainsi: 1500 W x 2h = 3000 Wh = Q40d x 1.16 x (40-15) _> Q40d = 100 litres En période d'heures creuses (de 22h à 6h par exemple), la résistance 15 Rb va être mis en service pour réchauffer les 200 litres situé en partie supérieure de 15 à 55 C, soit: x 1.16 x (55-15) = 9280 Wh soit 6,18 h de fonctionnement. 2891352 -3- Scenario 1 In the hypothesis of category A, we can consider the following scenario: Rh = 1500 W (high electrical resistance) Rb = 1500 W (low electrical resistance) Thconsn = 65 C (high thermostat set in setpoint) night) Thconsj = 40 C (high thermostat set in day setpoint) Tbconsn = 55 C (high thermostat set in night setpoint) Tbconsj: not used. (Low thermostat set to day setpoint) Assuming that the entire balloon is 15 C, during the 2-hour revival, Rh will be put into service from 17h to 19h providing: 1500 W x 2h = 3000 Wh = Q40d x 1.16 x (40-15) _> Q40d = 100 liters In periods of off-peak hours (from 22h to 6h for example), the 15 Rb resistor will be put into operation to warm up the 200 liters located in upper part of 15 to 55 C, ie: x 1.16 x (55-15) = 9280 Wh or 6.18 hours of operation.
Lors de l'arrêt de Rb, Rh va être mis en service pour chauffer les 100 litres de la partie haute de 55 à 65 C, soit: 100 x 1.16 x (65-55) = 1160 Wh soit 0,77 h de fonctionnement. When Rb is shut down, Rh will be commissioned to heat the 100 liters of the upper part of 55 to 65 C, ie: 100 x 1.16 x (65-55) = 1160 Wh or 0.77 hours of operation .
Lors des puisages ultérieurs, la capacité produite à 40 C sera de: Q40n x 1.16 x (40-15) = 100 x 1.16 x (55-15) + 100 x 1.16 x (65-15) _> Q40n = 360 litres En totalité, on aura pu puiser les 450 litres: jour à 40 C demandés pour obtenir la catégorie A. Selon une seconde caractéristique: l'intérêt de ce fonctionnement de notre Commande de charge est que la puissance d'une seule résistance est appelée à la fois. Ce qui permet de limiter la souscription de puissance abonnée (prime fixe). On subsequent drawing, the capacity produced at 40 C will be: Q40n x 1.16 x (40-15) = 100 x 1.16 x (55-15) + 100 x 1.16 x (65-15) _> Q40n = 360 liters all, we will have been able to draw the 450 liters: day to 40 C requested to obtain the category A. According to a second characteristic: the interest of this operation of our load control is that the power of a single resistance is called to the times. This makes it possible to limit subscriber power subscription (fixed premium).
2891352 -4- Scénario 2 Pour la catégorie B, on pourra par exemple ajuster les paramètres comme indiqués ci-dessous. 2891352 -4- Scenario 2 For Category B, you can, for example, adjust the parameters as shown below.
Une feuille de tableur, représentée Figure 2, permet de calculer les différentes conditions de fonctionnement en fonction de: É La puissance des résistances électriques Rh et Rb É Du volume à 40 C souhaité, *Des capacités Appoint total et Appoint jour disponible. A spreadsheet, shown in Figure 2, can be used to calculate the various operating conditions as a function of: É The power of the electrical resistances Rh and Rb É Of the desired volume at 40 C, * of the capacity of the total supply and the additional available day.
Scénario 3 Par ailleurs, si les trois sondes en partie basse, médiane et supérieure est supérieure à 40 C lors de l'arrivée du signal tarifaire heures creuses de la nuit, on pourra ajuster la température de consigne de la partie supérieure pour avoir juste 450 litres à 40 C disponible: On aura alors: x 1.16 x (Tsolaire 15 C) + 200 x 1.16 x (Tbconsn 15 C) = 450 x 1.16 x (40 15), dont il suffit d'extraire Tbconsn. Scenario 3 On the other hand, if the three probes at the bottom, median and upper probes are greater than 40 C during the arrival of the night-time tariff signal, we can adjust the set temperature of the upper part to have just 450 liters at 40 C available: We will then have: x 1.16 x (Tsolar 15 C) + 200 x 1.16 x (Tbconsn 15 C) = 450 x 1.16 x (40 15), from which it is sufficient to extract Tbconsn.
Pour optimiser la stratification, on pourra fixer une température différente pour Tbconsn et Thconsn, comme dans le scénario 1. To optimize the stratification, we can set a different temperature for Tbconsn and Thconsn, as in scenario 1.
La logique de fonctionnement est la suivante: Si la température du ballon solaire est suffisante c'est à dire apte à fournir l'eau chaude à température suffisante pour l'usager (en règle générale de l'ordre de 50 à 55 C), on ne met pas en route les résistances électriques; - Si ce n'est pas le cas, on met en route en heures creuses la résistance du haut: Rh, jusqu'à sa température de consigne, puis la résistance basse: Rb, jusqu'à sa température de consigne - A 17h (l'heure est obtenue à partir du signal Heures Creuses/Heures Pleines de EDF qui sert à caler une horloge interne au système), la résistance haute peut être remise en route si la réserve d'eau chaude est insuffisante, et jusqu'à une certaine température de consigne. The operating logic is as follows: If the temperature of the solar flask is sufficient, that is, capable of supplying hot water at a temperature sufficient for the user (generally of the order of 50 to 55 ° C), electrical resistances are not started; - If this is not the case, we start up in off-peak resistance: Rh, to its set temperature, then the low resistance: Rb, to its set temperature - At 17h ( the time is obtained from the EDF Hollow Hours / Full Hours signal used to calibrate an internal clock in the system), the high resistance can be restarted if the hot water supply is insufficient, and up to one hour. certain set temperature.
2891352 -5- Mise en oeuvre de l'invention: Pour mettre en oeuvre cette invention, il convient de disposer d'une carte électronique de commande disposant d'au moins: É 3 sondes de températures, É 2 signaux de commande des résistances Rh et Rb, É et 1 entrée permettant de connaître les heures creuses EDF. Implementation of the invention: To implement this invention, it is necessary to have an electronic control card having at least: É 3 temperature probes, É 2 control signals of the Rh resistors and Rb, É and 1 input allowing to know the EDF off-peak hours.
La détection de l'heure, pour la relance possible de 17h00 à 19h00, est détectée à partir des heures creuses EDF. The detection of the time, for the possible restart from 17:00 to 19:00, is detected from EDF off-peak hours.
Le dessin annexé illustre l'invention: La Figure 1 représente la réalisation de la cuve du chauffe-eau de 400 litres seulement, comportant: trois sondes de température (1), (2) et (3) ; - deux résistances chauffantes électriques immergées (4) et (5) un serpentin chauffant (6), disposé en partie basse Le tableau ci-dessous représente le schéma logique de commande, calculée sur tableur. The attached drawing illustrates the invention: FIG. 1 represents the embodiment of the tank of the water heater of only 400 liters, comprising: three temperature probes (1), (2) and (3); - two submerged electric heating elements (4) and (5) a heating coil (6), arranged at the bottom The table below represents the control logic diagram, calculated on a spreadsheet.
Le volume du ballon de 400 litres n'est qu'un cas d'exemple, et le fonctionnement de notre invention est valable pour tous autres types de capacités. The volume of the 400 liter flask is just one example, and the operation of our invention is valid for all other types of capacity.
