Abstract
Description
La présente invention a pour l'objet un procédé de réfrigération et de chauffage de liquides consommables, tels que eau, boissons et autres, et plus particulièrement la production et la distribution d'eau réfrigérée et d'eau chaude à volonté au moyen d'une fontaine, l'eau tempérée étant généralement livrée dans des bonbonnes placées à l'envers sur le distributeur.The subject of the present invention is a method of refrigeration and heating of consumable liquids, such as water, beverages and others, and in particular the production and distribution of chilled water and hot water at will by means of a fountain, with temperate water usually delivered in bottles placed upside down on the dispenser.
Une telle fontaine de capacité de l'ordre de 5 litres destinée à être placée, p.ex. dans les offices et les commerces, doit être d'un encombrement compatible sur le lieu de son installation elle doit, de ce fait, avoir des dimensions réduites.Such a fountain of capacity of the order of 5 liters intended to be placed, eg in offices and shops, must be a compatible space on the place of its installation must, therefore, have reduced dimensions.
On connaít déjà des fontaines fournissant de l'eau réfrigérée et de l'eau chaude, comme par exemple celle décrite dans le brevet russe n° RU 2 121 635. Selon ce brevet, la distribution se fait au moyen de deux réservoirs, dont celui destiné à fournir de l'eau réfrigérée est en contact avec la face froide d'une cellule à effet Peltier, tandis que l'eau destinée au réservoir d'eau chaude, est préchauffée par échange indirect de chaleur avec celle fournie par la face chaude de la cellule ci-mentionnée.We already know fountains providing water refrigerated and hot water, as described for example in the Russian patent No. RU 2 121 635. According to this patent, the distribution is by means of two tanks, one of which intended to provide chilled water is in contact with the face cold of a Peltier cell, while the water intended for hot water tank, is preheated by indirect exchange of heat with that provided by the hot face of the cell mentioned above.
Ainsi, les calories dissipées par la cellule du bac d'eau froide ne sont disponibles que lors du processus de réfrigération s'opérant dans le bac d'eau froide. On ne peut donc obtenir de préchauffage au moyen d'une cellule unique, que lorsqu'on produit en même temps de l'eau fraíche.Thus, the calories dissipated by the cell of the water tank cold are only available during the refrigeration process operating in the cold water tank. We can not get preheating by means of a single cell, only when produces at the same time fresh water.
En outre, le chauffage substantiel de l'eau du réservoir d'eau chaude s'effectue au moyen d'une résistance électrique plongée directement dans le réservoir d'où le danger de contamination.In addition, the substantial heating of the water tank Hot water is supplied by means of an electric heater diving directly into the reservoir from where the danger of contamination.
La demande de brevet japonais n° 10038431 décrit une installation volumineuse de purificateur d'eau pour usages domestiques et professionnels qui dispose des moyens pour la production d'eau fraíche et d'eau chaude à l'aide de deux générateurs contenant chacun une cellule à effet Peltier. L'eau purifiée accomplissant son rôle dans l'émission et dans l'absorption calorifique dans les éléments Peltier, retourne dans le réservoir de purification et de stockage et remplit dans ce circuit fermé le rôle indispensable de caloporteur.Japanese Patent Application No. 10038431 discloses a voluminous installation of water purifier for uses domestic workers and professionals who have the means to production of fresh water and hot water using two generators each containing a Peltier cell. The water purified performing its role in the broadcast and in heat absorption in the Peltier elements, returns to the purification and storage tank and fills in this circuit closed the indispensable role of coolant.
Un tel encombrement de l'espace accordé à la fontaine est tout à fait incompatible avec la nécessité de conserver un espace qui reste dans les limites de place attribuée à des fontaines à l'usage actuellement.Such a clutter of space granted to the fountain is completely incompatible with the need to conserve space which remains within the space limits attributed to fountains at the use currently.
La présente invention porte tout particulièrement sur la réalisation d'une fontaine permettant une économie importante d'espace tout en conservant des performances techniques et économiques en progrès.The present invention is particularly concerned with the realization of a fountain allowing a significant saving space while maintaining technical performance and economic progress.
Elle a pour l'objet un procédé de production d'eau réfrigérée et d'eau chaude au moyen d'une fontaine à usage domestique disposant de deux réservoirs séparés, dont chacun coopère avec une cellule à effet Peltier et qui sont munis de robinets de débit individuel ou simultané d'eau réfrigérée et d'eau chaude, chaque réservoir communiquant respectivement avec une face froide ou une face chaude de sa cellule.It is for the purpose a process for producing water refrigerated and hot water by means of a fountain for use house with two separate tanks, each of which cooperates with a Peltier cell and is equipped with single or simultaneous flow valves of chilled water and water each tank communicating respectively with a cold face or a hot face of his cell.
Elle est caractérisée en ce que la chaleur produite à la face chaude de la cellule appartenant au réservoir d'eau réfrigérée est transférée au moyen d'un échangeur de chaleur à la cellule appartenant au réservoir d'eau chaude.It is characterized in that the heat produced in the face hot cell belonging to the chilled water tank is transferred by means of a heat exchanger to the cell belonging to the hot water tank.
L'échangeur est de préférence une pièce en matériau présentant une bonne conductivité thermique, par exemple en aluminium ou en alliage d'aluminium, en forme de pont thermique conduisant la chaleur accumulée à la face chaude de la cellule du réservoir d'eau réfrigérée vers la face froide de la cellule du réservoir d'eau chaude. Il peut être muni des ailettes de refroidissement.The exchanger is preferably a piece of material having good thermal conductivity, for example in aluminum or aluminum alloy, shaped thermal bridge leading accumulated heat to the hot face of the cell's refrigerated water tank to the cold side of the cell of the hot water tank. It can be equipped with the fins of cooling.
L'eau tempérée en provenance de la bonbonne remplit le réservoir d'eau froide. A sa partie supérieure, à l'endroit où cette eau n'a pas encore subi le refroidissement programmé, débouche une conduite par laquelle l'eau en dérivation s'écoule vers le réservoir d'eau chaude et le remplit. Temperate water from the cylinder fills the cold water tank. At its upper part, where this water has not yet undergone the programmed cooling, opens a pipe through which the bypass water flows to the hot water tank and fills it.
De préférence, l'échangeur coopère avec un ventilateur, dont le fonctionnement asservi à un thermocouple inséré dans l'échangeur permet de réguler la température obtenue après échange.Preferably, the exchanger cooperates with a fan, whose operation is governed by a thermocouple inserted in the exchanger makes it possible to regulate the temperature obtained after exchange.
Selon une forme préférée de réalisation, la température de l'eau chaude disponible dans le réservoir est réglée par la tension électrique que l'on applique aux bornes de la cellule.According to a preferred embodiment, the temperature of hot water available in the tank is set by the voltage that is applied across the terminals of the cell.
Selon une autre forme préférentielle de réalisation, la température d'eau réfrigérée disponible dans le réservoir est pilotée au moyen d'une sonde de température placée au contact avec la paroi extérieure du réservoir d'eau froide, l'alimentation de la cellule étant asservie au fonctionnement de ladite sonde de température.According to another preferred embodiment, the refrigerated water temperature available in the tank is controlled by means of a temperature sensor placed in contact with the outer wall of the cold water tank, feeding of the cell being slaved to the operation of said probe of temperature.
L'invention a également pour l'objet une fontaine d'eau réfrigérée et d'eau chaude disposant de deux réservoirs séparés dont chacun coopère avec une cellule à effet Peltier et qui est caractérisée en ce qu'un échangeur en forme de barre, de pont ou d'entretoise conduisant la chaleur relie une face chaude de la cellule d'un réservoir à une face froide de la cellule de l'autre réservoir.The invention also for the object a water fountain refrigerated and hot water with two separate tanks each of which cooperates with a Peltier cell and which is characterized in that an exchanger in the form of a bar, bridge or spacer leading heat connects a hot face of the cell from one tank to a cold side of the cell from the other tank.
L'invention a également pour l'objet une installation pour la production selon les procédés sus-nommés de liquides consommables, en particulier tels que du thé, du café ou autres boissons pouvant être servis à volonté chauds, frais ou réfrigérées.The invention also has for the object an installation for production by the above-mentioned processes of liquids consumables, especially such as tea, coffee or other drinks that can be served at will hot, fresh or refrigerated.
D'autres caractéristiques apparaítront à la lumière de la description qui suit d'un mode de réalisation du procédé et qui est illustré par la figure décrivant l'installation et son mode de fonctionnement.Other characteristics will appear in the light of the following description of an embodiment of the method and which is illustrated by the figure describing the installation and its mode of operation.
Celle-ci comprend un réservoir 1 servant de cuve d'eau
réfrigérée et un réservoir 2 d'eau chaude. Sur le réservoir 1 est
placée une bonbonne 8 d'environ 5 litres d'eau et dont le col
inversé pénètre dans le réservoir après perçage d'un bouchon non
représenté.
La capsule 13 est munie d'un évent 9 pour la rentrée d'air.This comprises a tank 1 serving as a chilled water tank and a tank 2 of hot water. On the tank 1 is placed a cylinder 8 of about 5 liters of water and whose inverted neck enters the tank after drilling a plug not shown.
The capsule 13 is provided with a
L'eau tempérée en provenance de la bonbonne remplit le
réservoir d'eau froide 1. A la partie supérieure du réservoir
débouche une conduite 10 par laquelle de l'eau fraíche, c'est-à-dire
de l'eau n'ayant pas encore subi l'effet de refroidissement,
s'écoule pour se déverser et remplir le réservoir 2 d'eau chaude.
Près de l'endroit où débouche le courant d'eau fraíche de la
bonbonne est placé un déflecteur 11 conduisant ledit courant vers
la conduite 10.Temperate water from the cylinder fills the
cold water tank 1. At the top of the tank
opens a
Les robinets 3 et 4 débitent l'eau réfrigérée et l'eau chaude
à volonté, simultanément ou individuellement.
Les cellules 5 et 6 à effet Peltier sont placées au contact
direct des parois extérieures de cuves métalliques 1 et 2.Valves 3 and 4 dispense chilled water and hot water at will, simultaneously or individually.
Elles sont placées à effets inversés, c'est-à-dire avec la
face froide 5a au contact de la cuve 1 et avec la face chaude 6a au
contact de la cuve 2.They are placed in reverse effects, that is to say with the
cold face 5a in contact with the tank 1 and with the
Les faces de modules 5 et 6, opposées à celles au contact
de parois extérieures de cuves, c'est-à-dire la face chaude 5b de la
cellule 5 et la face froide 6b de la cellule 6 sont reliées entre elles
par un échangeur 7 qui est un corps solide, par exemple une barre
ou un pont thermique en aluminium ou en alliage d'aluminium,
présentant une bonne conductivité thermique, de façon à
transférer au moyen de l'échangeur 7 les calories rejetées par la
cellule 5 à la cellule 6 afin d'accroítre le rendement thermique de
l'opération.

Une sonde de température T1insérée dans l'échangeur 7
permet de réguler la température de l'échangeur pour éviter sa
surchauffe, grâce au ventilateur dont le fonctionnement est asservi
à la sonde de température T1. Ainsi, la sonde de température T1
sert à maintenir la température de l'échangeur à une température
optimum permettant à la cellule à effet Peltier (6) du réservoir (2)
d'eau chaude de fonctionner avec le meilleur rendement
calorifique.A temperature probe T1inserted in the
La température de l'eau chaude est régulée par la tension électrique appliquée aux bornes de la cellule (6).The temperature of the hot water is regulated by the voltage electric applied to the terminals of the cell (6).
Ainsi, cette cellule permet, par sa fonction de barrière thermique, d'élever la température de l'eau du réservoir 2 à la valeur désirée.Thus, this cell allows, by its barrier function thermal, to raise the temperature of the water from tank 2 to the desired value.
L'alimentation de la cellule 5 est asservie à la sonde de température T2 placée au contact de paroi du réservoir 1 d'eau réfrigérée. La température ainsi relevée peut par exemple piloter la durée de fonctionnement de la cellule 5 à effet Peltier, afin de couper le courant, lorsqu'il y a danger de la formation de cristaux de glace.The supply of the cell 5 is slaved to the probe of temperature T2 placed in contact with the wall of the tank 1 of water refrigerated. The temperature thus measured can for example drive the operating time of the Peltier effect cell 5, in order to switch off the power when there is danger of crystal formation of ice.
L'invention n'est pas limitée au mode de réalisation décrit à titre d'exemple mais elle s'applique à toutes les formes de réalisation à la portée de l'homme de l'art.The invention is not limited to the embodiment described by way of example but applies to all forms of realization within the reach of those skilled in the art.
Elle garde toute son utilité, car elle permet par le caractère compact de sa forme de réaliser les distributions d'eau réfrigérée et d'eau chaude, simultanément ou individuellement, dans un lieu d'utilisation de dimensions à peine supérieures à celles servant soit de l'eau réfrigérée soit de l'eau chaude.It keeps all its usefulness because it allows by the character compact of its form to achieve the chilled water distributions and hot water, simultaneously or individually, in a place use dimensions barely greater than those serving either chilled water or hot water.
