PURPOSE:To improve a performance of an outdoor heat exchanger by a method wherein an inclined part is formed at a side surface extending up to the lowermost end or the uppermost end in respect to the rotational direction of the propeller fan in an air guiding unit of a propeller fan with water dispersion ring. CONSTITUTION:An inclined part 15 is formed at a side surface of a propeller fan 10 with water dispersion rig. With this arrangement, the condensed water 14 dispersed in a circumferential direction by the water dispersion ring 12 is struck against the inclined part 15, dispersed to an outdoor heat exchanger 9 to improve a performance of the heat exchanger and at the same time no obstacles are found in the closed air passage, a disturbance of air flow is prevented and a noise of the device is reduced. |
