Abstract

The invention relates to a solar water heater with vacuum tubes operating under atmospheric pressure. It uses a heat exchanger in the form of a corrugated tube placed at the top of the tank. The tank is filled with still water which stores the heat from the solar radiation captured by the vacuum tubes. The water for use is heated by heat exchange from the still water through the corrugated tube. The water heater also supplies a central heating circuit.

Description

Capteur à tubes sous-vide fonctionnant à pression atmosphérique  Vacuum tube sensor operating at atmospheric pressure

Description  Description

La présente invention se rapporte aux capteurs solaires à usage de chauffage de l'eau.  The present invention relates to solar collectors for use in heating water.

Un chauffe-eau solaire, ce n'est pas un bloc unique qui produit de l'eau chaude, mais un ensemble d'éléments qui, raccordés, vont permettre au soleil de libérer l'énergie contenue dans sa lumière, et de chauffer l'eau sanitaire. Les éléments les plus communs sont : Un ou plusieurs capteurs absorbeurs ; un réservoir de stockage (intégré ou séparé) ; un vase d'expansion et un circuit de plomberie de transfert de la chaleur. Dans le cas d'une circulation forcée nous retrouvons également une pompe de circulation et un régulateur électronique. A solar water heater is not a single block that produces hot water, but a set of elements that, connected, will allow the sun to release the energy contained in its light, and heat the heat. sanitary water. The most common elements are: One or more absorber sensors; a storage tank (integrated or separate); an expansion vessel and a plumbing circuit for transferring heat. In the case of forced circulation we also find a circulation pump and an electronic regulator.

Deux types de capteurs majeurs existent : les capteurs plans et les capteurs à tubes sous vide. Nous nous intéressons dans le cadre de notre invention aux capteurs à tube sous vide car elle appartient à cette catégorie. Two types of major sensors exist: flat collectors and vacuum tube collectors. We are interested in our invention vacuum tube collectors because it belongs to this category.

Un capteur à tubes sous vide est constitué d'une série de tubes transparents sous vide qui isolent l'absorbeur. On fait le vide dans ces tubes, comme dans les bouteilles isothermes afin de réduire les déperditions de chaleur par convection et par conduction thermique. A vacuum tube sensor consists of a series of transparent vacuum tubes that isolate the absorber. These tubes are evacuated, as in insulated bottles, in order to reduce heat losses by convection and thermal conduction.

Ce type de capteurs réagit avec moins d'inertie que les capteurs conventionnels ; Ils s'échauffent plus rapidement, ils permettent de mieux tirer parti des petites périodes d'ensoleillement, ils permettent de mieux profiter de l'éclairement du soleil du matin et du soir.  This type of sensor reacts with less inertia than conventional sensors; They warm up faster, they allow better take advantage of small periods of sunshine, they can better enjoy the sunlight in the morning and evening.

Comme les capteurs à tubes sous vide peuvent atteindre des températures extrêmes de plus de 150° C, le fluide caloporteur est spécialement développé pour ce genre d'installation. La tuyauterie du circuit voyant passer le fluide à plus de 150° C, les tubes en cuivre ne sont soudés à l'étain. As evacuated tube collectors can reach extreme temperatures of more than 150 ° C, the heat transfer fluid is specially developed for this type of installation. Since the piping of the circuit lights the fluid at more than 150 ° C, the copper tubes are not soldered with tin.

Les déperditions étant réduites par rapport à celles d'un capteur plan vitré, le rendement est nettement supérieur.  The losses are reduced compared to those of a flat glazed sensor, the yield is significantly higher.

Plusieurs types de capteurs à tubes sous vide existent. Les tubes sous vide à flux direct utilisent un fluide caloporteur qui passe directement par l'absorbeur dans les tubes sous vide. Un rendement élevé est obtenu par ce transfert thermique direct. On peut par ailleurs orienter l'absorbeur par rapport au soleil au moment de l'installation, ce qui en fait un très bon capteur pour les implantations en façade par exemple. Les tubes sous vide à caloduc quant à eux, contiennent une petite quantité d'eau (ou un liquide antigel selon les consignes de température). Ce liquide est vaporisé sous vide partiel et cette vapeur s'élève dans le conduit de l'absorbeur, se condense dans le condenseur et retourne sous forme liquide dans l'absorbeur. Le condenseur transfère la chaleur au fluide de transfert thermique. Several types of vacuum tube collectors exist. Direct flow vacuum tubes use a coolant that passes directly through the absorber into the vacuum tubes. High efficiency is achieved by this direct heat transfer. We can also orient the absorber in relation to the sun at the time of installation, which makes it a very good sensor for implantations frontage for example. The heat pipe vacuum tubes meanwhile, contain a small amount of water (or antifreeze liquid according to the temperature setpoints). This liquid is vaporized under partial vacuum and this vapor rises in the duct of the absorber, condenses in the condenser and returns in liquid form in the absorber. The condenser transfers the heat to the heat transfer fluid.

D'autres technologies amliorent les tubes sous vides en utilisant par exemple l'effet thermos ou les tubes schott/sydney qui diminuent les déperditions de chaleur.  Other technologies improve vacuum tubes by using for example the thermos effect or schott / sydney tubes which reduce heat loss.

Notre invention est également un capteur solaire thermique de chauffage de l'eau utilisant les tubes sous vide avec la particularité de garder la pression à l'intérieur des tubes sous vide et du réservoir de stockage à pression atmosphérique. Ceci est possible grâce à un flotteur installé à l'entrée d'eau du réseau. Une électrovanne et un capteur de niveau reliés à un régulateur électronique remplacent le flotteur dans certains modèles. Le liquide caloporteur utilisé à l'intérieur du tube et du réservoir est une eau avec ou sans antigel selon le besoin. Our invention is also a solar thermal water heating sensor using vacuum tubes with the particularity of keeping the pressure inside the vacuum tubes and the storage tank at atmospheric pressure. This is possible thanks to a float installed at the water inlet of the network. A solenoid valve and a level sensor connected to an electronic controller replace the float in some models. The coolant used inside the tube and tank is water with or without antifreeze as needed.

Le capteur est composé de plusieurs absorbeurs à tubes sous vide ( 1 ) installés sous un réservoir (2) et contenant de l'eau stagnante. Le chauffage est effectué directement par effet thermospyhon. Un échangeur thermique (7) sous forme de tube ondulé en inox est installé à l'intérieur du réservoir, immergé dans la partie supérieure et chaude. Ses extrémités (6) sont l' entrée et la sortie de l' eau d'utilisation. Le réservoir est alimenté également depuis le réseau d'eau courante. L'échangeur thermique pour eau (7) est courbé afin d'épouser la forme cylindrique du réservoir en haut et maximiser ainsi la température en contact avec l'échangeur étant donné que l'eau chauffée remonte en haut du réservoir.  The sensor is composed of several vacuum tube absorbers (1) installed under a tank (2) and containing stagnant water. The heating is carried out directly by thermospyhon effect. A heat exchanger (7) in the form of corrugated stainless steel tube is installed inside the tank, immersed in the upper part and hot. Its ends (6) are the inlet and the outlet of the water of use. The tank is also fed from the running water network. The water heat exchanger (7) is curved to fit the cylindrical shape of the tank at the top and thus maximize the temperature in contact with the exchanger since the heated water rises to the top of the tank.

Dans le cas d'utilisation d'électrovanne au lieu de flotteur, dès que le capteur de niveau indique le remplissage du réservoir, l'électrovanne arrête le flux, et l'eau stagnante ainsi récupérée est utilisée pour emmagasiner l'énergie thermique captée par les tubes sous vide. Un régulateur électronique assure ce fonctionnement. Lorsque le détecteur de niveau indique une baisse due à l'échappement par la soupape, l'électovanne est réouverte pour laisser entrer l'eau dans le réservoir. In the case of use of solenoid valve instead of float, as soon as the level sensor indicates the filling of the tank, the solenoid valve stops the flow, and the stagnant water thus recovered is used to store the thermal energy captured by the vacuum tubes. An electronic regulator ensures this function. When the level sensor indicates a drop due to the exhaust valve, the solenoid valve is reopened to let water into the tank.

Une soupape (8) permet l'évacuation de l'eau évaporée depuis le réservoir pour garder la pression atmosphérique à l'intérieur du réservoir et des tubes sous vide.  A valve (8) allows evacuation of evaporated water from the tank to maintain atmospheric pressure inside the tank and vacuum tubes.

Le réservoir extérieur (3) est en acier galvanisé revêtu d'une peinture époxy électrostatique. Il contient une isolation (4) en laine de verre pour limiter les déperditions de chaleur. Le réservoir intérieur (5) est en acier inox 304 2B. The outer tank (3) is made of galvanized steel coated with an electrostatic epoxy paint. It contains a glass wool insulation (4) to limit heat loss. The inner tank (5) is made of 304 2B stainless steel.

Le chauffe-eau chauffe également l'air de chauffage central qui traverse le réservoir dans un échangeur (9) relié avec le circuit de chauffage.  The water heater also heats the central heating air which passes through the tank in an exchanger (9) connected with the heating circuit.
