Abstract

The water heater is semi spherical (1) allowing continuous solar exposure whatever the time of day and has a black coil (2) in copper wound to match the inside surface of the heater. The exterior coil (2) is connected to an interior coil (4) that acts as the heat exchanger for the sanitary water in the balloon. An electric resistance heater (14) operates when there is little sunshine, and two probes (11,12) start or stop the pump (5) to prevent water circulation in the outer coil when the exterior temperature falls to a value that would cool the already heated water in the hemisphere.

Description

DE SCRI?T ION
La Présente invention concerne les instruments du type" chauffe eau solaire"destinés à la production d'eau chaude.OF SCRIPT ION
The present invention relates to instruments of the "solar water heater" type intended for the production of hot water.

Les dispositifs connus de ce genre ne nermettent pas une exposition maximum et continue aux rayons solaires,sinon par 1' utilisation de commandes motorisées.De même,aucun ne permet ltéchange des calories et l'accumulation dans le même appareil, le stokage se fait indépendamment du capteur. Known devices of this kind do not allow maximum and continuous exposure to the sun's rays, except through the use of motorized controls. Similarly, none allows the exchange of calories and accumulation in the same device, storage is done independently of the sensor.

La "Demi-sphère solaire", selon l'invention permet d'évit -er ces inconvénients.ta forme demi-sphérique de l'appareil permet une exposition maximum et continue aux rayons solaires quelle que soit l'heure de la ajourne, I1 est caractérisé par un serpentin noir épousant la forme demi-sphérique du ballon éliminant ainsi les problèmes de dilatation et permettant une grande surface de chauffe. The "solar half-sphere" according to the invention makes it possible to avoid these drawbacks. Your semi-spherical shape of the device allows maximum and continuous exposure to the sun's rays whatever the time of the day, I1 is characterized by a black coil conforming to the semi-spherical shape of the balloon thus eliminating the problems of expansion and allowing a large heating surface.

Ce serpentin extérieur est relié à un serpentin intéri -eur servant d'échangeur A l'eau sanitaire accumulée dans le ballon permettant l'association du capteur et de lgaccumulateur dans le mdme appareil. This external coil is connected to an internal coil serving as an exchanger for the sanitary water accumulated in the tank allowing the association of the sensor and the accumulator in the same device.

Celui-ci peut être réalisé à des dimentions plus import -antes suivants les besoins.Il est intéressant de noter que le volume de stokage est double si l'on augmente le rayon de la @@ sphère d'une dizaine de centimètres seulement. This can be done in more important dimensions depending on the needs. It is interesting to note that the storage volume is double if the radius of the @@ sphere is increased by only about ten centimeters.

En cas de journée peu ensoleillée,l'appoint de calories peut être fait par la résistance placée dans l'appareil. In case of a bad day, the calories can be added by the resistance placed in the device.

le dessin de la planche 1/3 est une vue en éclaté du schéma de fonctionnement,celui de la planche 2/3 est une vue en éclaté du dispositif à échelle indiquée,et celui de la planche 3/3 représente la vue de dessous du dispositif et montre les différents raccordements. the drawing of sheet 1/3 is an exploded view of the operating diagram, that of sheet 2/3 is an exploded view of the device on a scale indicated, and that of sheet 3/3 represents the bottom view of the device and shows the different connections.

Tel qu'il est représenté,le dispositif comporte une demisphère(1)sur laquelle est enroulé un sernentin(2)recouvert lui meme d'une demi-sphbre en plexiglas(3).e serpentin extérieur est relié à un serpentin intérieur échangeur(4).Une pompe(5) fait circuler l'eau de lléchangeur,au serpentin extérieur en passant par un clapet de retenue(6) ,une pompe de sécurité(7) et un Té de règlage(8).Une vanne(9)permet le remnlissage du circuit du capteur solaire.Un vase d'expansion(lO)compense la dilatation de l'eau.teux sondes(ll)et(l2)reliées au coffret de régulation(13)mettent en route ou arrêtent la pompe suivant les températures intérieures et extérieures au ballon. As shown, the device comprises a hemisphere (1) on which is wound a sernentin (2) itself covered with a plexiglass half-sphere (3). The external coil is connected to an internal exchanger coil ( A pump (5) circulates the water from the exchanger to the external coil, passing through a check valve (6), a safety pump (7) and an adjusting tee (8). ) allows re-smoothing of the solar collector circuit. An expansion tank (10) compensates for the expansion of the water. two probes (ll) and (12) connected to the control box (13) start or stop the pump depending on the inside and outside temperatures of the tank.

Un chauffage d'appoint constitué d'une résistance éleo- -trique(l4)oommandée par un aquastat(15)permet de compenser éventuellement la faiblesse du rayonnement solaire.Un manomè- -tre(16)indique en continu,la pression du capteur.Un purgeur(17)placé au point le plus haut du serpentin permet de purger l'air au remplissage. A backup heater made up of an electric-resistance (14) controlled by an aquastat (15) can possibly compensate for the weak solar radiation. A pressure gauge (16) continuously indicates the pressure of the sensor .A trap (17) placed at the highest point of the coil allows the air to be purged during filling.

Entre la demi-sphbre métallique et le serpentin,un isolant(18)permet de conserver les calories.Une trappe de visi- -te boulonnée(19) donne accès i l'intérieur pour le montage et le démontage de l'échangeur interne.Un groupe de sécurité(21) protège le circuit sanitaire et un robinet de vidange(23) permet de vidanger le circuit solaire.Trois pseds(24)suppor- -ten.t la demi-sphère.  Between the metal half-sphere and the coil, an insulator (18) makes it possible to conserve calories. A bolt-on visor door (19) gives access to the interior for mounting and dismounting the internal exchanger. A safety group (21) protects the sanitary circuit and a drain valve (23) allows the solar circuit to be drained. Three pseds (24) support the half-sphere.

L'sppareil,obJet de l'invention,peut Stre implanté sur une terrasse,une pelouse,un jardin,une cour,à un endroit pré -sentant les meilleures conditions d'exposition aux rayons solaires;il peut outre réalisé à des dimensions beaucoup plus importantes suivant les besoins sanitaires ou de chauffagecentral.  The apparatus, object of the invention, can be installed on a terrace, a lawn, a garden, a courtyard, in a place presenting the best conditions of exposure to the solar rays; it can besides realized to dimensions much more important according to sanitary or central heating needs.
