PURPOSE:To suppress the splashing of condensed water scraped up from a water receiver and to efficiently spray the condensed water to an outdoor side heat exchanger. CONSTITUTION:Blades 8 for scraping up condensed water are disposed at separate positions at the front side of a propeller fan 6 to be rotated coaxially with the fan 6. The blades 8 are so formed in shape as to scrape up condensed water W with respect to a rotating direction thereby to suppress splashing of the water W by its centrifugal force to efficiently spray it to an outdoor air side heat exchanger. In order to prevent the blades 8 from being deformed in the shape by its centrifugal force, the blades 8 are so set in shape at an angle as to anticipate a deformation due to the force that the angle of the blade 8 to the condensed water surface becomes the optimum when the blade 8 is deformed by the force generated at the time of rotating the blade 8. |
