Abstract

L'invention concerne un appareil de conditionnement d'air océanique, lequel sert à l'humidification d'air ambiant à l'aide d'eau minéralisée, en particulier d'eau contenant du sel marin. Cet appareil comporte une entrée d'air, un ventilateur disposé à l'entrée d'air et servant à générer un flux d'air, un récipient d'eau ouvert vers le haut et un dispositif d'humidification qui peut être traversé par le flux d'air et est disposé dans la direction d'écoulement. Le dispositif d'humidification est réalisé en tant que bloc d'évaporation à action capillaire et pourvu d'orifices d'écoulement, lequel bloc d'évaporation plonge dans le récipient d'eau. On peut ainsi obtenir une capacité d'évaporation considérablement plus élevée que dans les appareils traditionnels. Le flux d'air généré par le ventilateur peut être orienté ou guidé à l'intérieur de l'appareil de telle sorte qu'au moins une partie du flux d'air vient en contact avec la surface de l'eau contenue dans le récipient d'eau et met cette eau en mouvement. Ainsi, une recirculation continuelle de la réserve d'eau se trouvant dans le récipient d'eau est obtenue sans nécessiter de pompe à eau.
