Abstract

The swimming pool heating method uses solar energy, a cover (9) of material absorbing the radiation being placed partly or completely over it, and in contact with the water. A pump is used to generate movement in the water, exchanging the surface water with that at the bottom. The pump can be of the immersed and turbine or propeller type (1) with axial flow, driven by a submerged electric motor (2), and enclosed by a housing (3) which directs the water towards the bottom and round the motor to cool the latter. There can be a main float (4) keeping constant pumping at the surface, and an auxiliary floating cover (5) to regulate the degree of immersion and protect the intake.

Description

La présente invention concerne un procédé permettant l'utilisation de l'énergie solaire pour le réchauffage de piscines ou bassins extérieurs,ou couverts de matériaux transparents. La surface des piscines est fréquemment recouverte,pendant les périodes de non utilisation,par une couverture flottante de plastique noir destinée à limiter les pertes de chaleur. Cette couverture absorbe également pendant le jour le rayonnement solaire,et réchauffe liteau du bassin immédiatement à son contact.Elle joue donc le roule d'un absorbeur solaire classique sans vitrage. Maîs l'eau ainsi réchauffée,se trouvant à la pDxtie la plus haute du bassin,ne peut pas circuler par convection naturelle,et reste au contact de lsabsorbeur flottant. L'échan- ge de chaleur entre l'absorbeur et l'eau est ainsi trés rapidement arrenté. Pour obtenir un véritable effet de captation de l'énergie solaire,il est necessaire de créer un courant permettant le renouvellement de l'eau chauffée par l'absorbeur. C'est le but de la présente invention,qui peut donc remplacer les systèmes classiques de réchauffage solaire par capteurs extérieurs,pourvu que le bassin puisse être couvert totalement ou en partie,durant au moins une partie de la journée.Le cout d'installation de la présente invention sera alors bien inférieur à celui des systèmes classiques. The present invention relates to a method allowing the use of solar energy for heating swimming pools or outdoor pools, or covered with transparent materials. The swimming pool surface is frequently covered, during periods of non-use, by a floating cover of black plastic intended to limit heat loss. This cover also absorbs solar radiation during the day, and heats the pelvis strip immediately on contact, so it plays the roll of a conventional solar absorber without glazing. However, the water thus heated, being at the highest point of the basin, cannot circulate by natural convection, and remains in contact with the floating absorber. The heat exchange between the absorber and the water is thus very quickly settled. To obtain a real effect of capturing solar energy, it is necessary to create a current allowing the renewal of the water heated by the absorber. This is the purpose of the present invention, which can therefore replace conventional solar heating systems with external collectors, provided that the pool can be covered in whole or in part, for at least part of the day. of the present invention will then be much lower than that of conventional systems.

te procédé selon l'invention consiste: - à installez à la surface du bassin une ou plusieurs pompes flottan-tes maintenues en position fixe par des cables arrimés au bord du bassin. te method according to the invention consists: - to install on the surface of the basin one or more floating pumps-your maintained in a fixed position by cables stowed at the edge of the basin.

- à recouvrir sa surface d'une couverture absorbante en contact avec liteau. - to cover its surface with an absorbent cover in contact with battens.

Dés que le rayonnement solaire chauffe l'eau superficielle par l'intermédiaire de la couverture absorbante,la ou les pompes flottantes se mettent automatiquement en marche et créent un courant convectif inversé,échangeant l'eau superficielle réchauffée,avec l'eau plus froide du fond du bassin. L'énergie solaire recueillie par la couverture est donc transférée à tout le volume du bassin. As soon as the solar radiation heats the surface water via the absorbent cover, the floating pump or pumps automatically start and create an inverted convective current, exchanging the heated surface water, with the colder water of the bottom of the basin. The solar energy collected by the cover is therefore transferred to the entire volume of the basin.

Un mode de réalisation d'un appareil pour la mise en oeuvre du procédé selon l'invention est illustré par la figure I (vue en coupe). I1 consiste en une pompe immergée à écoulement axial maintenue en surface par des flotteurs. La turbine ou lthélice(I),mue par le moteur électrique immergé(2),aspire l'eau de surface réchauffée aucontact de la couverture absorbante(9),et la refoule vers le fond du bassin à l'intérieur du carter(3) 4ui la dirige et permet,par son écoulement autour du moteur,le refroidissement de celui-ci et la récupération sous forme de chaleur utile de-l1énergie électrique consommée. Le flotteur(4) ainsi que le eapot-flotteur(5) maintiennent l'appareil juste en surface.Le capot-flotteur(5) a deux fonctions: il empêche la couverture absorbante d'obstruer ltentree de l'eau dans l'appareil,et il sert de flotteur auxiliaire réglant l'immersion afin que le sommet de l'appareil émerge tout juste. n doit être sufisamment lourd pour empêcher le flotteur principal (4) d'émerger. Son épaisseur doit entre faible pour que la prise d'eau reste bien en surface. La ligne de flottaison de l'appareil doit se situer à peu prés en son milieu.Le relais thermostatique(6) commande automatiquement la mise en marche ou L'arrêt de la pompe lorsque la température de l'eau superficielle dépasse ou devient inférieure à des valeurs préréglables. le cable(7) supportant un cable électrique permet d'amener l'énergie électrique à l'appareil et,avec le cable(8),il le maintient en position fixe dans le bassin. An embodiment of an apparatus for implementing the method according to the invention is illustrated in Figure I (sectional view). I1 consists of a submerged axial flow pump maintained on the surface by floats. The turbine or propeller (I), driven by the submerged electric motor (2), sucks the heated surface water on contact with the absorbent cover (9), and discharges it towards the bottom of the basin inside the casing (3 ) 4ui directs it and allows, by its flow around the motor, the cooling of the latter and the recovery in the form of useful heat of the electrical energy consumed. The float (4) and the eapot-float (5) hold the device just above the surface.The float cover (5) has two functions: it prevents the absorbent cover from obstructing the entry of water into the device , and it serves as an auxiliary float regulating the immersion so that the top of the device just emerges. It must be heavy enough to prevent the main float (4) from emerging. Its thickness must be between small so that the water intake remains well on the surface. The water line of the device must be located approximately in the middle. The thermostatic relay (6) automatically controls the starting or stopping of the pump when the surface water temperature exceeds or falls below preset values. the cable (7) supporting an electric cable makes it possible to bring the electrical energy to the device and, with the cable (8), it maintains it in a fixed position in the basin.

L'invention s'applique à l'utilisation de l'énergie solaire au réchauffage des piscines non utilisées en permanence,ou de tous autres bassins pouvant être couverts totalement ou partiellement par une couverture absorbante: bassins à usages industriels,bassins d'aquaeulture,de pisciculture. The invention applies to the use of solar energy for heating swimming pools which are not used permanently, or of any other basins which can be completely or partially covered by an absorbent cover: basins for industrial uses, aquaure basins, of fish farming.

Bien entendu,l'invention n'est nullement limitée au mode de réalisation décrit et représenté qui n'a-été donné qu'à titre d'exemple. Elle comprend tous les moyens constituant des équivalents techniques du procédé décrit,ainsi pue leurs combinaisons suivant l'esprit de l'invention.  Of course, the invention is in no way limited to the embodiment described and shown which has been given only by way of example. It includes all of the means constituting technical equivalents of the process described, and thus their combinations according to the spirit of the invention.
