Abstract

De manière classique, il n'existait pas de climatiseurs extérieurs aptes à refroidir et à chauffer une grande zone extérieure. A cet effet, l'invention concerne un climatiseur extérieur (100), lequel climatiseur renferme, à l'intérieur d'un boîtier (10), un compresseur (1), un échangeur de chaleur côté source de chaleur (6), un premier ventilateur (7), un échangeur de chaleur côté utilisation (3), et un second ventilateur (4). Le boîtier (10) a, formé à l'intérieur de celui-ci : un premier orifice de sortie (29) qui décharge vers le haut de l'air qui a traversé l'échangeur de chaleur côté source de chaleur (6) ; et des seconds orifices de sortie (31a – 31d) qui sont positionnés plus bas que le premier orifice de sortie (29), et qui déchargent, dans la direction horizontale, de l'air qui a traversé l'échangeur de chaleur côté utilisation (3).
