Title
(EN) REHEAT DEHUMIDIFICATION SYSTEM IN VARIABLE SPEED APPLICATIONS
(FR) SYSTEME RECHAUFFEUR DESHUMIDIFICATEUR A APPLICATIONS DE VITESSE VARIABLES
Abstract
(EN) A refrigerant system is provided with a reheat function selectively utilizing the heat rejected by the variable speed drive controller and electronics that are often employed in known refrigerant cycles. By placing at least one of these variable speed drives in the path of air being delivered to an environment to be conditioned, the air is reheated to a desired temperature, after it has been overcooled in the evaporator to provide a desired humidity level. In the manner, the variable speed drive is cooled, and the reheat function is provided, without the requirement of any flow structure.
(FR) L'invention concerne un système de réfrigération à fonction de réchauffeur permettant d'exploiter sélectivement la chaleur rejetée par le contrôleur d'unité d'entraînement à vitesse variable, et une électronique, fréquemment utilisés pour des cycles de réfrigération existants. En plaçant au moins l'une des unités d'entraînement à vitesse variable sur le trajet de l'air fourni à l'environnement climatisé, on réchauffe l'air à la température souhaitée, après super-refroidissement dans l'évaporateur, pour fournir tel ou tel niveau d'humidité. Cela permet de refroidir l'unité d'entraînement à vitesse variable et d'assurer la fonction de réchauffeur, sans structure de flux supplémentaire.
