L'invention concerne un procédé de rafraîchissement de l'air ambiant par atomisation permanente et horizontale d'eau, assistée d'une ventilation d'air pulsé pour couvrir une zone sectorielle programmable assuré par l'entraînement d'un moteur pas à pas. The invention relates to a method of cooling the ambient air by permanent and horizontal atomization of water, assisted by forced air ventilation to cover a programmable sectoral area provided by the drive of a stepping motor.
Les procédés de rafraîchissement d'air ambiant traditionnels utilisent l'atomisation d'eau dans la plupart des cas. Ces atomisations, bien connues, se font avec des buses hydrauliques utilisant de l'eau sous pression ; ou des buses hydrau-pneumatiques utilisant un mélange d'eau sous pression et d'air comprimé. Traditional ambient air cooling processes use water atomization in most cases. These well-known atomizations are carried out with hydraulic nozzles using pressurized water; or hydro-pneumatic nozzles using a mixture of pressurized water and compressed air.
Une buse atomise l'eau sur une surface circulaire de 1 à 2 mètres de diamètre, en moyenne. Généralement un quadrillage de la zone à rafraîchir est fait au dessus de celle-ci, à 3 ou 4 mètres de hauteur environ, et un nombre de buse est défini en fonction de la zone couverte par chacune d'elle, puisqu'elles atomisent l'eau de haut en bas. Quand le système est utilisé au dessus d'une terrasse de café, par exemple, des gouttes, très gênantes pour la clientèle tombent de chaque buse hydraulique aux interruptions de cycle nécessairement intermittent par leur concept. D'autres procédés d'atomisation d'eau avec des buses hydraupneumatiques, accompagnées ou non d'une ventilation assistée sont utilisés de façon horizontale fixe et unidirectionnelle. A nozzle atomizes water on a circular surface of 1 to 2 meters in diameter, on average. Generally a grid of the area to be refreshed is made above it, at 3 or 4 meters in height, and a number of nozzles is defined according to the area covered by each of them, since they atomize l from top to bottom. When the system is used above a coffee terrace, for example, drops, very annoying for customers fall from each hydraulic nozzle to cycle interruptions necessarily intermittent by their concept. Other water atomization processes with hydraupneumatic nozzles, with or without assisted ventilation, are used in a fixed and unidirectional horizontal manner.
L'objet de l'invention est de concilier, dans un appareil fixe ou mobile, les avantages des techniques existantes : atomiser en permanence l'eau sous pression avec une buse hydraulique, assisté d'une ventilation d'air pulsé pour en augmenter la portée à l'horizontale, avec un balayage sectoriel réglable pour augmenter l'étendue de couverture de la zone à rafraîchir de façon significative. The object of the invention is to reconcile, in a fixed or mobile device, the advantages of existing techniques: permanently atomizing water under pressure with a hydraulic nozzle, assisted by forced air ventilation to increase the carried horizontally, with an adjustable sector sweep to significantly increase the extent of coverage of the area to be refreshed.
La portée de la buse, assistée d'air pulsé, devient un rayon d'action pour couvrir une zone secteurisée circulaire réglable, assurée par l'entraînement d'un moteur pas à pas programmable. The range of the nozzle, assisted by forced air, becomes a range of action to cover an adjustable circular sectored area, ensured by the drive of a programmable stepper motor.
L'utilisation d'une buse traditionnelle, à action verticale de haut en bas, dans la plus part des cas, couvre 3,14 m2 pour un diamètre d'action de 2 mètres. The use of a traditional nozzle, with vertical action from top to bottom, in most cases, covers 3.14 m2 for an action diameter of 2 meters.
Cette même buse, utilisée à l'horizontal, assistée d'air puisé, pour la démonstration porte l'eau atomisée à 4 mètres de distance, par exemple, pour la démonstration. Selon l'invention, sans l'assistance du vent naturel extérieur, ces 4 mètres deviennent le rayon d'action avec une atomisation d'eau sur un secteur angulaire de 300 naturel d'atomisation de l'eau, et, avec un balayage motorisé on peut obtenir une couverture sur 360 , soit 50,24 m2 minimum. On constate donc un coefficient multiplicateur de 12. This same nozzle, used horizontally, assisted by pulsed air, for the demonstration carries the atomized water 4 meters away, for example, for the demonstration. According to the invention, without the assistance of the natural outside wind, these 4 meters become the radius of action with a water atomization over an angular sector of 300 natural water atomization, and, with a motorized sweep you can get 360 coverage, or 50.24 m2 minimum There is therefore a multiplying coefficient of 12.

De manière générale l'invention consiste a atomiser en permanence de l'eau (1) par l'action d'au moins une buse hydraulique d'atomisation à jet plat (2), de préférence dans cette démonstration, par exemple, située, par exemple, à l'intérieur d'une goulotte (3) dont la section réduite (4) accélère sa vitesse et modifie la section circulaire du jet d'air (5) en jet plat, produit par un ventilateur centrifuge (6), par exemple, et destiné à prolonger l'action de l'eau atomisée (17) en sortie de la buse (2). L'eau (1) est injectée dans une buse (2), ou dans des buses (2 ; 2bis ; 2ter), par exemple, qui peut ou peuvent être soit à t'intérieur soit à l'extérieur de la goulotte (3), en dessous par exemple selon la figure 5. L'eau est mise sous une pression suffisante pour assurer une bonne atomisation, par exemple 70 bar, ou plus, avec une pompe hydraulique électrique (7) dans cet l'exemple, équipé de préférence d'un variateur de vitesse électronique, ou mécanique (7bis) qui permet d'atomiser exactement la quantité d'eau nécessaire tout en conservant la pression d'eau désirée et de réduire ainsi le bruit, bien connu, de la pompe hydraulique (7) jusqu'à la rendre pratiquement silencieuse. A chaque aspiration de la pompe hydraulique (7), l'eau (1) en provenance du réseau urbain (8) passe à travers un robinet d'arrêt de sécurité (9) et un filtre (10) qui enlève les particules d'impureté dans l'eau et la purifie de ces bactéries par l'adjonction d'un traitement, bien connu, d'ionisation par exemple, puis un clapet anti-retour (11). Par refoulement de la pompe hydraulique (7), l'eau (1) circule au travers un second clapet anti-retour (12), le clapet anti-retour (11) assurant sa fonction de fermeture, puis une électrovanne (13) qui s'ouvre pour que l'eau (1) arrive dans la buse d'atomisation (2) quand la pompe hydraulique (7) refoule l'eau sous pression. Une tuyauterie souple (14), par exemple, suffisamment long, assure l'alimentation de l'eau (1) pendant qu'un plateau de balayage (15) est mis en mouvement par un moteur pas à pas (16) qui permet un balayage de l'eau atomisée (17) sur un secteur angulaire (18) par exemple, réglable de 0"à 360" (en Fig : 2 et 6). Dans la démonstration la buse d'atomisation (2) est judicieusement positionnée (en Fig : 4) pour que le jet d'eau atomisée (17), dans sa partie supérieur (19) soit emmenée au loin (20) par un air propulsé (5) In general, the invention consists in permanently atomizing water (1) by the action of at least one hydraulic atomizing nozzle with flat jet (2), preferably in this demonstration, for example, located, for example, inside a chute (3) whose reduced section (4) accelerates its speed and modifies the circular section of the air jet (5) into a flat jet, produced by a centrifugal fan (6), for example, and intended to prolong the action of atomized water (17) at the outlet of the nozzle (2). Water (1) is injected into a nozzle (2), or into nozzles (2; 2bis; 2ter), for example, which can or can be either inside or outside the chute (3 ), below for example according to FIG. 5. The water is put under sufficient pressure to ensure good atomization, for example 70 bar, or more, with an electric hydraulic pump (7) in this example, equipped with preferably an electronic or mechanical speed controller (7bis) which makes it possible to atomize exactly the quantity of water required while maintaining the desired water pressure and thus reduce the well-known noise of the hydraulic pump ( 7) until making it practically silent. Each time the hydraulic pump (7) is drawn in, the water (1) from the urban network (8) passes through a safety shut-off valve (9) and a filter (10) which removes particles of impurity in water and purifies it from these bacteria by adding a well-known treatment, for example ionization, then a check valve (11). By discharge of the hydraulic pump (7), the water (1) circulates through a second non-return valve (12), the non-return valve (11) ensuring its closing function, then a solenoid valve (13) which opens so that the water (1) arrives in the atomization nozzle (2) when the hydraulic pump (7) delivers the water under pressure. A flexible pipe (14), for example, long enough, ensures the supply of water (1) while a sweeping plate (15) is set in motion by a stepping motor (16) which allows a scanning of atomized water (17) on an angular sector (18) for example, adjustable from 0 "to 360" (in Figs: 2 and 6). In the demonstration, the atomizing nozzle (2) is judiciously positioned (in Fig: 4) so that the atomized water jet (17), in its upper part (19) is carried away (20) by a propelled air (5)

Le positionnement de la buse d'atomisation (2) peut changer en fonction de l'effet souhaité dans la configuration de la zone à rafraîchir. accelerated out of a narrowed mouth (4) of a chute (3). The positioning of the atomizing nozzle (2) can change depending on the desired effect in the configuration of the area to be cooled.
Dans une forme d'évolution, l'appareil peut être équipé de fonctions complémentaires, pour une meilleure prestation et pour plus de souplesse d'utilisation (Fig : 3) : d'une cuve rechargeable ou d'une cartouche interchangeable d'eau (21), de source par exemple, dans laquelle une sonde de pompage (22) alimentant la pompe hydraulique (7), est plongée pour y pomper de l'eau (23). Un robinet d'arrêt (24), comme le robinet d'arrêt (9), permet de sélectionner la source d'alimentation de l'eau (1) ou (23). Un groupe froid, ou une pile Thermochimique (25), bien connus et disponibles sur le marché, permet de refroidir l'eau sélectionnée (1) ou (23). La pile Thermochimique permet, quant à elle de refroidir ou la réchauffer l'eau à une température que l'on peut sélectionner, dans ces extrêmes, entre moins 500 Centigrade et plus 800 Centigrade, ce qui peut ouvrir d'autres débouchés d'utilisation à l'appareil comme dans des serres de culture ou des saunas qui demandent de l'humidité chaude, exemples non limitatif. Refroidir l'eau sélectionnée aux alentours de 1 à 2 Centigrade augmente l'efficacité de l'appareil en provoquant un plus grand écart de température entre l'eau atomisée (17) et l'air ambiant extérieur. L'eau atomisée (17) commence à refroidir l'air avant de se réchauffer pour s'évaporer et donner la sensation de fraîcheur recherchée tout en diminuant la consommation d'eau nécessaire dû à cette double action. Un distributeur (26) : de parfum ; d'insecticide ; de désinfectant ou d'engrais, exemples non limitatifs, modifie l'eau avant qu'elle soit atomisée. In a form of evolution, the device can be equipped with additional functions, for better performance and more flexibility of use (Fig: 3): a refillable tank or an interchangeable water cartridge ( 21), from a source for example, in which a pumping probe (22) supplying the hydraulic pump (7) is immersed in order to pump water (23) there. A stopcock (24), like the stopcock (9), allows to select the water supply source (1) or (23). A cold group, or a thermochemical stack (25), well known and available on the market, makes it possible to cool the selected water (1) or (23). The thermochemical stack allows to cool or heat the water to a temperature that can be selected, in these extremes, between minus 500 Centigrade and plus 800 Centigrade, which can open up other outlets for use with the apparatus as in greenhouses of culture or saunas which require hot humidity, nonlimiting examples. Cooling the selected water to around 1 to 2 Centigrade increases the efficiency of the device by causing a greater temperature difference between the atomized water (17) and the outside ambient air. The atomized water (17) begins to cool the air before heating to evaporate and give the desired feeling of freshness while reducing the water consumption required due to this double action. A distributor (26): of perfume; insecticide; disinfectant or fertilizer, nonlimiting examples, modifies the water before it is atomized.
La Fig 6 démontre t'efficacité du balayage sectoriel. La buse (2), sur un plateau de balayage (15) en position de repos, couvre une zone sectorielle (27) de 30 avec une portée de 4 mètres soit 4,19 M2 sans vent naturel additionnel extérieur. La surface couverte de 4,19 M2 est déjà supérieur aux 3,14 M2 couvert par une buse d'atomisation utilisée seule et à la vertical avec un diamètre maximal d'action de 2 mètres. Quand l'atomisation de l'eau est faite pendant un balayage sectoriel (18) à 360 , la surface couverte par un angle sectoriel de 300 se trouve multipliée par 12, soit une surface totale couverte de 50,24 M2. Fig 6 demonstrates the efficiency of sector scanning. The nozzle (2), on a sweeping plate (15) in the rest position, covers a sectoral area (27) of 30 with a range of 4 meters, ie 4.19 M2 without additional external natural wind. The covered area of 4.19 M2 is already greater than the 3.14 M2 covered by an atomization nozzle used alone and vertically with a maximum action diameter of 2 meters. When water atomization is done during a sectoral sweep (18) at 360, the surface covered by a sectoral angle of 300 is multiplied by 12, that is to say a total covered surface of 50.24 M2.
Le procédé selon l'invention est particulièrement destiné au rafraîchissement de l'air ambiant par atomisation permanente horizontale d'eau, assistée d'une ventilation d'air pulsé pour couvrir une zone sectorielle plus étendue programmable assuré par l'entraînement d'un moteur pas à pas. The method according to the invention is particularly intended for cooling the ambient air by permanent horizontal atomization of water, assisted by a forced air ventilation to cover a larger sectoral area programmable provided by the drive of a motor. step by step.
