Abstract

L'invention porte sur un procédé d'alimentation en air d'un climatiseur vertical. Dans le procédé, un dispositif d'alimentation en air de climatiseur est disposé dans un canal d'air interne d'un corps de climatiseur, le climatiseur vertical envoie de l'air d'échange de chaleur dans le canal d'air interne après qu'il a été échangé à travers un échangeur de chaleur vers un canal d'air traversant à partir d'un canal d'air d'échange de chaleur, et aspire de l'air ne servant pas à l'échange de chaleur à l'extérieur du climatiseur vertical dans le canal d'air traversant à partir d'une entrée d'air ne servant pas à l'échange de chaleur, l'air d'échange de chaleur et l'air ne servant pas à l'échange de chaleur formant un air mélangé et étant ensuite envoyés à partir d'une sortie d'air mélangé à travers le canal d'air traversant, et l'écoulement de l'air ne servant pas à l'échange de chaleur étant de 0,05 à 0,5 fois celui de l'air d'échange de chaleur. L'air d'échange de chaleur dans le climatiseur et l'air ne servant pas à l'échange de chaleur à l'extérieur du climatiseur sont mélangés selon une certaine proportion et envoyés simultanément, de telle sorte que le volume d'entrée d'air du climatiseur est accru, que l'écoulement d'air intérieur est accéléré, que la douceur de sortie d'air à partir du climatiseur peut être améliorée, et que l'expérience de confort d'un utilisateur est améliorée.
