Abstract

La présente invention concerne un climatiseur vertical et son dispositif (1) d'alimentation en air. Le dispositif (1) d'alimentation en air du climatiseur vertical comprend trois corps (11, 12, 13) de guidage d'air annulaires qui sont pénétrés dans le milieu et pourvus d'ouvertures avant et arrière, chacun des corps (11, 12, 13) de guidage d'air annulaires consistant en un élément unique, les trois corps (11, 12, 13) de guidage d'air annulaires étant agencés en séquence de l'avant vers l'arrière, un conduit d'air pénétrant qui est pénétré de l'avant vers l'arrière est formé dans le milieu, une entrée (122) d'air d'un corps (12) de guidage d'air annulaire d'extrémité arrière agencé au niveau de l'extrémité arrière forme une entrée d'air de non-échange de chaleur du dispositif d'alimentation en air, une sortie (111) d'air d'un corps (11) de guidage d'air annulaire d'extrémité avant agencé au niveau de l'extrémité avant forme une sortie d'air mélangé, des conduits (14, 15) d'air d'échange de chaleur annulaires sont formés entre deux corps (11, 12, 13) de guidage d'air annulaires adjacents, et un ensemble d'attribution (16) d'écoulement d'air permettant d'attribuer de manière circonférentielle l'air d'échange de chaleur est agencé dans au moins un conduit (14, 15) d'air d'échange de chaleur annulaire. Le climatiseur vertical adoptant ledit dispositif (1) d'alimentation en air est uniforme en termes d'alimentation en air, présente un volume d'alimentation en air important et une température d'alimentation en air appropriée.
