Abstract

La présente invention concerne un dispositif hybride de refroidissement dont la petite taille est appropriée à un usage domestique et qui produit de l'eau froide tout en conservant de l'énergie en utilisant l'eau chaude obtenue à partir d'une chaleur résiduaire provenant de la cogénération ou de la chaleur solaire, ce qui empêche la condensation sur un plancher ou un plafond si de la rosée se forme sur une surface lors d'un refroidissement par rayonnement nocturne, et qui peut sélectivement refroidir ou chauffer le plancher au moyen d'un équipement existant chauffant l'eau. Le dispositif hybride de refroidissement comprend : un appareil de déshumidification-refroidissement constitué d'un corps de déshumidification-refroidissement qui est divisé en un passage de déshumidification-refroidissement et un passage de régénération, un rotor de déshumidification monté rotatif dans le passage de déshumidification-refroidissement et le passage de régénération afin d'éliminer l'humidité dans l'air qui est introduit dans le passage de déshumidification-refroidissement, un échangeur de chaleur pour chauffer l'air qui traverse le passage de régénération pour régénérer le rotor de déshumidification, un refroidisseur pour produire l'eau froide par pénétration de l'air, duquel est éliminée l'humidité lorsqu'il traverse le rotor de déshumidification, dans l'eau qui est pulvérisée par un dispositif de diffusion et au moyen de la chaleur latente provenant de l'évaporation de l'eau; un ventilateur qui propulse l'air à l'intérieur du passage de déshumidification-refroidissement et du passage de régénération; et un dispositif d'alimentation d'eau froide servant à récupérer l'eau froide qui est produite dans le refroidisseur et à acheminer celle-ci de manière à ce qu'elle circule dans un espace climatisé.
