Abstract

The present invention relates to a water heater in which the water is heated with solar hot air. The exchange of heat between the air and the water can take place: via hot-air ducts, either directly - the hot-air ducts being "embedded" in hydrated salts whose storage capacity will be used; or via networks of tubes or coils, either directly - the tubes being in the air, or indirectly - the tubes being embedded in hydrated salts; or directly, the hot air being admitted into a network of appropriate tubes which are connected together at each end by distribution chambers, the unit being placed inside the water tank to be heated. The air circuit formed by the collectors, casings, fan and heat exchanger is closed. Varying the speed of the fan as a function of the temperature allows the latter to be modulated as required.

Description

La présente invention concerne un chauffe-eau dans lequel l'énergie provient d'air réchauffé dans des capteurs solaire à air.The present invention relates to a water heater in which the energy comes from air heated in solar air collectors.

Dans les chauffe-eau solaires connus, l'eau est réchauffée directement par rayonnement. I1 en résulte, soit des risques de gel si on chauffe directement 11 eau d'utilisation, soit l'emploi d'un double circuit, le circuit primaire avec échan- geur contenant un liquide antigel.In known solar water heaters, the water is heated directly by radiation. This results in either the risk of freezing if the water for use is heated directly, or the use of a double circuit, the primary circuit with exchanger containing an antifreeze liquid.

De plus, il n'est pas possible de moduler la température en fonction de 11 ensoleillement. In addition, it is not possible to modulate the temperature as a function of the sunshine.

Dans la présente invention, il n'y a pas de risque de gel 11 échangeur étant placé à l'interieur des bâtiments - et la température de l'air est modulée en fonction de l'ensoleillement par variation du débit de l'air.In the present invention, there is no risk of frost 11 exchanger being placed inside the buildings - and the air temperature is modulated according to the sunshine by variation of the air flow.

Selon la température d'eau désirée, on fait varier le débit de l'air pour obtenir la température correspondant à celle donnant à l'eau la température voulue
Selon qu'il s'agira du chauffage d'eau destinée à des usages sanitaires ou au chauffage, plusieurs systèmes - tous basés sur le principe : air chaud à température modulée, échangeur air/ eau - sont possibles.Depending on the desired water temperature, the air flow is varied to obtain the temperature corresponding to that giving the water the desired temperature
Depending on whether it is the heating of water intended for sanitary uses or for heating, several systems - all based on the principle: hot air at modulated temperature, air / water exchanger - are possible.

L'air réchauffé par le rayonnement solaire a sa température modulée par variation du débit grâce à un ventilateur (V) dont la vitesse varie en fonction de l'ensoleillement (fig. 1).The air heated by solar radiation has its temperature modulated by variation of the flow rate thanks to a fan (V) whose speed varies according to the sunshine (fig. 1).

Cet air est soufflé dans un caisson (C) contenant l'ensemble échangeur.This air is blown into a box (C) containing the exchanger assembly.

L'air est repris à la sortie du caisson, est rewsoufflé dans les capteurs.The air is taken out of the box, is blown back into the sensors.

Il s'agit dtun circuit fermé. Une sonde sécurité empochera tOL excès de chaleur, soit à l'eau, soit au capteur. It is a closed circuit. A safety probe will pocket any excess heat, either with water or with the sensor.

1 - Le caisson peut contenir : les absorbeurs (A) de caloducs munis d'ailettes appropriées pour permettre le meilleur échange air/caloducs ; les condenseurs (C) - également munis d'ailettes permettant un bon échange avec l'eau - plongent dircctement dans le ballon d'eau sanitaire. 1 - The box can contain: the heat absorbers (A) provided with suitable fins to allow the best air / heat exchange; the condensers (C) - also fitted with fins allowing good exchange with the water - dive directly into the domestic water tank.

@ - Le caisson peut contenir : @ la place des absorbeurs de caloducs, des serpentins, de piéféronce en cuivre, munis d'ailettes calculées pour permet-- tre un b@n échange. @ - The box can contain: @ instead of the heat pipe absorbers, coils, copper piezoelectric, fitted with fins calculated to allow a good exchange.

Dans ces tubes en serpentins ou en nappes, reliés par collecteurs, circule - par I l'intermédiaire de deux colonnes montantes et de deux colonnes descendantes l'eau à réchauffer provenant du ballon et l'eau réchaullée y retournant.In these serpentine or sheet tubes, connected by collectors, circulates - by means of two rising columns and two descending columns the water to be heated coming from the balloon and the reheated water returning to it.

Cette circulation est possible par l'intermédiaire dun circulateur. This circulation is possible via a circulator.

3 - Le caisson peut contenir des réservoirs plus ou moins plats (R) contenant des sels hydratés dont la température de fusion correspond à celle désirée pour l'eau ; Dans ces sels, sont placés les absorbeurs (A) des caloducs. Sur ces calodues peut être soudée de part et d'autre, sur deux génératrices médiales horizontales, mie ailette plane pour augmenter l'échange et uniformiser la température du sel assurant le stockage et le transfert de chaleur au tube du caloduc.3 - The box can contain more or less flat tanks (R) containing hydrated salts whose melting temperature corresponds to that desired for water; In these salts, the absorbers (A) of the heat pipes are placed. On these heat pipes can be welded on either side, on two horizontal medial generators, a flat fin to increase the exchange and standardize the temperature of the salt ensuring storage and transfer of heat to the heat pipe.

On augmente ainsi la capacité de stockage et on régularise mieux la température.This increases the storage capacity and regulates the temperature better.

Bacs ou réservoirs à sels et caisson constituent un échangeur.Salt tanks or tanks and caissons constitute an exchanger.

les bacs sont disposées dans le caisson afin de permettre le meilleur échange possible, les deux Races et un ceté du réser- voir étant léchés par l'air circulant en chicane - les recipients étant placés les uns au-dessus des autres en chicane de façon a assurer un tel circuit. the tanks are arranged in the box to allow the best possible exchange, the two Races and a tank block being licked by the air circulating in baffle - the containers being placed one above the other in baffle so to ensure such a circuit.

I,es condenseurs des caloducs plongent directement dans l'eau du ballon.I, the heat pipe condensers plunge directly into the balloon water.

' - Le caisson peu contenir à la place des caloducs, de simples tubes en matériau conducteur résistant à la corrosion des sels. '- The box can contain, instead of heat pipes, simple tubes of conductive material resistant to salt corrosion.

Ces tubes ailetés ou non , selon les caractéristiques de l'échangeur fonction des besoins, assurent la circulatioll - dans le bain echangeur stocker - du liquide à réchauffer par l'intermédiaire de deux colonnes montantes et de deux colonnes descendantes sur lesquelles sont branchés, par l'intermédiaire d'un circulateur, l'arrivée dteau à réchauffer et le retour de l'eau réchauffée, prise et retournant directement dans le ballon.These finned tubes or not, depending on the characteristics of the exchanger according to needs, ensure the circulation - in the exchanger bath to store - of the liquid to be heated by means of two risers and two descenders to which are connected, by through a circulator, the arrival of water to be heated and the return of the heated water, taken and returned directly to the tank.

5 - Le caisson échangeur: peut être simplement constitué par un réseau tubùlaire (R) bon conducteur, aileté ou non selon les besoins, placé directement dans le ballon (B) contenant l'eau à réchauffer.5 - The exchanger box: can simply be constituted by a tubular network (R) good conductor, finned or not as required, placed directly in the tank (B) containing the water to be heated.

Les tubes constituant le réseau sont soudés de part et d'autre des deux caissons de répartition recevant d'un côté l'air chaud venant des capteurs, reprenant de l'autre côté l'air refroidi qui est re-soufflé dans les capteurs selon le principe déjà exposé.The tubes constituting the network are welded on either side of the two distribution boxes receiving on one side the hot air coming from the sensors, taking on the other side the cooled air which is re-blown into the sensors according to the principle already stated.

Il est évident que, selon la surface des capteurs installés, les caractéristiques de l'échangeur prévues en fonction de la modulation de la température de l'air et la capacité du stocka- ge, le même principe peut ttr-e retenu tout autant pour le ohauf- fage de l'eau sanitaire que pour celui de l'eau d'un chauffage central ou par plancher chauffant. It is obvious that, depending on the surface area of the sensors installed, the characteristics of the exchanger provided as a function of the modulation of the air temperature and the storage capacity, the same principle can be adopted just as much for the heating of domestic water only for that of central heating water or underfloor heating.
