Description
La présente invention concerne un dispositif pour climatiser l'ambiance d'une pièce en abaissant la température et diminuant le poids d'eau contenu dans l'air. Il est fixé au mur, positionné en partie supérieure.The present invention relates to a device for air conditioning the ambience of a room by lowering the temperature and decreasing the weight of water contained in the air. It is fixed to the wall, positioned in the upper part.
Traditionnellement, les appareils de climatisation sont équipés d'un ventilateur. Ce qui entraîne une nuisance sonore et un effet de courant d'air nuisible à la santé et au confort intérieur. Ces appareils nécessitent une installation électrique et entraîne donc une consommation électrique.Traditionally, air conditioning units are equipped with a fan. This leads to a noise and a draft effect harmful to health and comfort. These devices require an electrical installation and therefore leads to an electrical consumption.
Certains modèles sont dépourvus de ventilateur mais nécessitent :
- un faux plafond pour leur installation, ce qui complique l'installation et pénalise les coûts
- une alimentation en air déjà climatisé, générée par une ventilation mécanique centralisée (VMC)
- pour créer l'effet d'induction indispensable au brassage de l'air ambiant à traiter
- pour baisser le poids d'eau de l'air ambiant afin d'éviter le phénomène de condensation sur l'échangeur lui-même - phénomène que l'on redoute dans ce cas, puisqu'aucune solution ne permet de collecter et d'évacuer l'eau de condensation du traitement de la chaleur latente, qui le cas échéant inonderait les plafonds et fuirait dans la pièce.
- a false ceiling for their installation, which complicates the installation and penalizes the costs
- an already air-conditioned air supply, generated by a centralized mechanical ventilation (VMC)
- to create the inductive effect essential to the mixing of the ambient air to be treated
- to reduce the water weight of the ambient air in order to avoid the condensation phenomenon on the exchanger itself - a phenomenon that is feared in this case, since no solution can collect and evacuate the condensation water from the latent heat treatment, which, if any, would flood the ceilings and leak into the room.
Le dispositif selon l'invention permet de remédier à ces inconvénients. Il comporte un échangeur thermique incliné (1), d'un angle notamment de 45°, alimenté en eau froide ou chaude par un refroidisseur de liquide réversible. La conduite de l'eau de condensation vers un collecteur est assurée grâce à l'inclinaison de l'échangeur maintenu par les supports muraux inclinés(3). Le panneau de façade (2) constituant l'habillage prévu pour le confort visuel inclut, à sa partie basse et sur toute la longueur, un collecteur d'eau de condensation (5) à raccorder sur un système d'évacuation gravitaire.The device according to the invention overcomes these disadvantages. It comprises an inclined heat exchanger (1), in particular an angle of 45 °, supplied with cold or hot water by a reversible liquid cooler. Condensation water is fed to a collector by the inclination of the exchanger held by the inclined wall supports (3). The front panel (2) constituting the covering provided for visual comfort includes, at its lower part and over the entire length, a condensing water collector (5) to be connected to a gravity evacuation system.
Le dispositif fonctionne par convection naturelle, l'air est mis en circulation par différence de température entre l'ambiance et l'échangeur. Cette circulation d'air naturelle ainsi obtenue constitue le débit d'air nécessaire pour climatiser l'ambiance de la pièce. Le dispositif fonctionne sans ventilateur et donc sans aucune émission sonore ni consommation électrique. Le fonctionnement par convection naturelle rend le dispositif autorégulant, un fort écart de température génère un fort échange et à l'inverse un faible écart ne génère qu'un faible échange. II peut néanmoins, selon les principes traditionnels être équipés en option d'une vanne à eau glacée qui régule le débit d'eau glacée en fonction des besoins de l'occupant géré par un thermostat mural ou une commande quelle qu'elle soit.The device operates by natural convection, the air is circulated by temperature difference between the atmosphere and the exchanger. This natural air circulation thus obtained is the air flow needed to cool the atmosphere of the room. The device operates without fan and therefore without any noise emission or power consumption. The operation by natural convection makes the self-regulating device, a large temperature difference generates a strong exchange and conversely a small gap generates only a small exchange. It may nevertheless, according to traditional principles be optionally equipped with a chilled water valve that regulates the flow of chilled water according to the needs of the occupant managed by a wall thermostat or any order.
L'échangeur thermique comprend un arrangement d'ailettes à géométrie de l'angle d'inclinaison de l'échangeur notamment 45°.
L'échangeur est caractérisé par une grande surface d'échange permettant de remonter le régime de température d'eau glacée à une valeur beaucoup moins consommatrice d'énergie électrique par le refroidisseur de liquide, notamment 15°C. Le dimensionnement de la surface de passage d'air assure une vitesse de circulation d'air imperceptible aux occupants.The heat exchanger comprises a fin arrangement with geometry of the angle of inclination of the exchanger in particular 45 °.
The exchanger is characterized by a large exchange surface making it possible to raise the chilled-water temperature regime to a value much less consuming electrical energy by the liquid cooler, in particular 15 ° C. The dimensioning of the air passage surface ensures an air circulation speed imperceptible to the occupants.
Le dispositif comporte un déflecteur (4) au dessous de l'échangeur, fixé aux supports muraux, permettant de dévier une partie d'air refroidi en partie haute dans l'ambiance. Il est incliné vers l'avant et comporte un rebord sur toute sa longueur permettant le captage des gouttes rebelles de condensation qui pourraient tomber avant l'arrivée dans le collecteur. Il comporte un profilé central (9) faisant appui sur le collecteur, lui donnant un profil bombé dans sa longueur permettant l'écoulement de l'eau captée vers les profilés d'extrémités (10) intégrés au déflecteur. Ces deux profilés d'extrémités reposant sur le collecteur d'eau du panneau d'habillage conduisent l'eau captée vers celui-ci.The device comprises a baffle (4) below the exchanger, fixed to the wall supports, for deflecting a portion of air cooled in the upper part in the environment. It is inclined forwards and has a rim along its entire length allowing the capture of rebellious drops of condensation that could fall before arrival in the collector. It comprises a central section (9) bearing on the collector, giving it a curved profile in its length allowing the flow of water collected to the end profiles (10) integrated in the deflector. These two end profiles resting on the water collector of the trim panel conduct the water collected thereto.
Selon des modes particuliers de réalisation,
- un filtre à air peut être placé en amont de l'échangeur
- le système peut être réversible et fonctionner en chauffage s'il est alimenté en eau chaude.
- Pour les cas de fonctionnement à régime de condensation élevée, l'échangeur du dispositif comportera des ailettes avec une surépaisseur d'extrémité à profil ovoïde sur la longueur (
fig. 4 ) assurant la conduite des gouttes de condensation vers le collecteur.
- an air filter can be placed upstream of the exchanger
- the system can be reversible and operate in heating if it is supplied with hot water.
- For high condensing operation cases, the exchanger of the device will comprise fins with an ovoid profile end allowance over the length (
Fig. 4 ) driving the drops of condensation to the collector.
