PROBLEM TO BE SOLVED: To suppress deviation of temperature distribution in an air-conditioned room.SOLUTION: Horizontal blades (41a, 41b, 41c, 41d) of an indoor unit (10) perform a first swing operation for rotating from an upper angle (P0) to a lower angle (P5), and then, for rotating from the lower angle (P5) to the upper angle (P0). Also, the horizontal blades (41a, 41b, 41c, 41d) perform a second swing operation at least once for rotating upward temporarily and then for rotating downward, during the time until the rotation angle reaches the lower angle (P5) from the upper angle (P0) out of the first swing operation. In the second swing operation, the horizontal blades (41a, 41b, 41c, 41d) rotate up to a horizontal blowing angle (Pc) above the upper angle (P0).SELECTED DRAWING: Figure 7 |
