Abstract

L'invention porte sur une unité extérieure, qui élimine une diminution de température d'air humidifié, et qui empêche une condensation à l'intérieur d'un trajet pour de l'air humidifié. Dans l'unité extérieure (30), à l'aide d'un second conduit d'humidification (180) qui est disposé au voisinage d'une unité de composant électrique (55), une diminution de température du second conduit d'humidification lui-même est éliminée, et, en résultat, une diminution de température de l'air à haute température et à humidité élevée passant à l'intérieur de celui-ci est éliminée, empêchant une condensation à l'intérieur du second conduit d'humidification (180). Egalement, une chambre de machine (42), au niveau de laquelle quasiment la totalité du second conduit d'humidification (180) est disposée, et une chambre de soufflante (41), au niveau de laquelle un échangeur de chaleur extérieur (33) est disposé, sont séparées, et, par conséquent, de l'air qui a traversé l'échangeur de chaleur extérieur (33) est, pour la plus grande partie, empêché de s'écouler à l'intérieur de la chambre de machine (42), et, pendant une opération de chauffage, le refroidissement du second conduit d'humidification (180) à l'aide d'un air à basse température qui a traversé l'échangeur de chaleur extérieur (33) est évité.
