PROBLEM TO BE SOLVED: To provide an air conditioning device securing reaching of warm air to a floor surface to improve comfort in a heating operation. SOLUTION: This air conditioning device is equipped with an indoor unit 1 having: a heat exchanger 5; a fan 7; and an upper blade 10 and a lower blade 11 for vertically changing the direction of supplied wind by rotating the fan 7. When the heating operation is stable, an angle of at least one of the upper blade 10 and the lower blade 11 is changed according to an air volume to increase a flow velocity of the wind. A temperature of a floor surface is increased by preventing floating of warm air by increasing the flow velocity of the warm air, thus comfort is improved. COPYRIGHT: (C)2011,JPO&INPIT |
