Abstract

L'invention porte sur un climatiseur (10), qui comprend : un boîtier de climatisation (21) ; un filtre (40), qui est renfermé à l'intérieur du boîtier de climatisation et qui filtre de l'air ; des échangeurs de chaleur (42, 44), qui échangent de la chaleur avec l'air qui a traversé le filtre ; des portes de climatisation (84a, 84b, 46a, 46b) qui se déplacent de telle sorte que l'état d'écoulement de l'air qui a traversée le filtre est amené à varier ; des actionneurs (50a, 50b, 90a, 90b) qui entraînent les portes de climatisation de façon à déplacer ces dernières ; et des mécanismes de transmission de puissance (51a, 51b, 91a, 91b), qui transmettent la sortie d'entraînement des actionneurs aux portes de climatisation pour entraîner les portes de climatisation. A l'intérieur du boîtier de climatisation, les actionneurs et les mécanismes de transmission de puissance sont positionnés en aval du filtre dans la direction d'écoulement de l'air.
