Abstract

Un dispositif à deux blocs pour refroidir et déshumidifier l'air dans un espace conditionné intérieur comprend des première et seconde voies séparées, créées à partir d'un courant d'air entrant. La première voie passe par un dispositif dessiccant pour retirer l'humidité de l'air, l'air sortant du dispositif dessiccant passant par un premier serpentin de refroidissement pour refroidir l'air et l'air sortant du premier serpentin de refroidissement entrant dans un plenum d'air d'alimentation. La seconde voie traverse un premier côté d'un échangeur de chaleur, l'air sortant de l'échangeur de chaleur étant chauffé par un élément chauffant avant d'absorber l'humidité du dispositif dessiccant. L'air sortant du dispositif dessiccant passe par un second côté de l'échangeur de chaleur, et passe ensuite par un second serpentin de refroidissement pour refroidir ou déshumidifier l'air dans la seconde voie. L'air sortant est mélangé avec l'air de la première voie et ramené dans l'espace conditionné dans lequel l'écoulement d'air de traitement est maximisé par rapport à l'écoulement d'air de régénération tout en permettant encore le refroidissement latent effectif.A two-block device for cooling and dehumidifying air in an indoor conditioned space comprises first and second separate channels created from an incoming air stream. The first lane passes through a desiccant device to remove moisture from the air, the air exiting the desiccant device passing through a first cooling coil to cool the air and the air exiting the first cooling coil entering a plenum of supply air. The second path passes through a first side of a heat exchanger, the air exiting the heat exchanger being heated by a heating element before absorbing moisture from the desiccant device. The air leaving the desiccant passes through a second side of the heat exchanger, and then passes through a second cooling coil to cool or dehumidify the air in the second lane. The outgoing air is mixed with the air from the first channel and returned to the conditioned space in which the process airflow is maximized relative to the regeneration air flow while still allowing cooling. latent effective.
