Title (EN) AIR CONDITIONER
(FR) CLIMATISEUR
(JA) 空気調和機
Abstract:
(EN) Provided is a very quiet air conditioner in which noise in a range from 2NZ sound to 3NZ sound is reduced. The air conditioner (10) is equipped with a heat exchanger (30) and a crossflow fan (40). The cylindrical crossflow fan (40) is provided with multiple impellers (41) in which multiple blades (42) are arranged in the circumferential direction. The heat exchanger (30) is arranged upstream from the crossflow fan (40) in the airflow direction, with a gap (In) having a size of no greater than 20% of the diameter of the impellers (41) therebetween. The multiple impellers (41) are arranged such that one or more of the multiple blades of adjacent impellers (41) are offset from each other. Between 14 and 30 impellers (41) are arranged along the rotational axis in the crossflow fan (40).
(FR) Climatiseur très silencieux dans lequel le bruit dans une plage allant d'un son de 2NZ à un son de 3NZ est réduit. Le climatiseur (10) est équipé d'un échangeur de chaleur (30) et d'un ventilateur à flux transversal (40). Le ventilateur à flux transversal cylindrique (40) est pourvu de multiples roues (41) dans lesquelles de multiples pales (42) sont agencées dans la direction circonférentielle. L'échangeur de chaleur (30) est agencé en amont du ventilateur à flux transversal (40) dans la direction d'écoulement d'air, avec un espace (In) d'une taille de pas plus de 20 % du diamètre des roues (41) entre celles-ci. Les multiples roues (41) sont agencées de telle sorte qu'une ou plusieurs des multiples pales de roues adjacentes (41) sont décalées les unes des autres. Entre 14 et 30 roues (41) sont agencées le long de l'axe de rotation dans le ventilateur à flux transversal (40).
(JA) 2NZ音から3NZ音までの騒音が低減された静粛性の高い空気調和機を提供する。気調和機(10)は、熱交換器(30)とクロスフローファン(40)とを備えている。円筒状のクロスフローファン(40)は、複数の翼(42)を周方向に配列した羽根車(41)を複数設けたものである。熱交換器(30)は、羽根車(41)の直径の20%以下の寸法の隙間(In)をあけてクロスフローファン(40)の空気流れ上流側に配置されている。複数の羽根車(41)は、互いに隣接する羽根車(41)の複数の翼のうちの少なくとも1つが位置ずれして配列されている。クロスフローファン(40)においては、14個以上30個以下の羽根車(41)が回転軸に沿って並べられている。
