Abstract

La présente invention concerne un climatiseur (10), dans lequel au moins un module de compresseur (40a) et au moins un module d'échangeur de chaleur côté source de chaleur (50) sont mutuellement espacés et reliés par l'intermédiaire d'une canalisation, les au moins un module de compresseur (40a) et au moins un module d'échangeur de chaleur côté source de chaleur (50) étant combinés avec un module d'échangeur de chaleur côté utilisation (21) pour constituer une partie d'un cycle de fluide frigorigène. Le module d'échangeur de chaleur côté source de chaleur (50) est choisi parmi l'un ou une combinaison quelconque d'un module d'échangeur de chaleur de premier type (50a) depuis lequel de l'air est soufflé vers le haut, d'un module d'échangeur de chaleur de deuxième type (50b) depuis lequel de l'air est soufflé latéralement, et d'un module d'échangeur de chaleur de troisième type (50c) depuis lequel de l'air est soufflé dans une direction oblique. Une telle configuration permet de mettre en œuvre un climatiseur (10) ayant une configuration optimale conforme aux spécifications de conception d'un bâtiment.
