Abstract:
According to the present invention, a suction port (14) and a blowout port (15) are formed in a casing (11). A fan (12) is provided inside the casing (11). Under test conditions in which a blower is provided so that a reference position (Q) of the blowout port (15) is a position 2,000 mm separated upward from a floor surface, an air flow adjustment mechanism (20) adjusts the flow of air blown out from the blowout port (15) so that in a wide mode, the average air speed in a first range (R11) and the average air speed in a second range (R12) are approximately equal to each other, and the magnification ratio of the average air speed in a third region (R13) to the average air speed in the first range (R11) is less than 1.5 times.
