PURPOSE: An air-conditioner is provided to improve energy efficiency and to prevent the decreasing of heating and cooling efficiency by controlling air blast direction. CONSTITUTION: An air-conditioner which can control air blow using a turbulence stimulator comprises a guide plate(130), first and second guide bars(140,150), first and second pinion, first and second drive motors, and first and second flaps. The turbulence stimulator has first and second guide grooves in a longitudinal direction. The first and second guide bars are inserted into the first and second guide grooves to slide up and down and comprises first and second racks on the one lower end. The first and second pinions are meshed with the first and second racks. The first and second drive motors drives first and second pinions, respectively. First and second flaps of three angles plate shape are linked with the first and second guide bars. The first and second flaps are hinged with the guide plate.
