Air conditioner

摘要

Object: To provide an air conditioner in which, at the time of heating, a downward reachability in a room while a louver is moved rotationally below a predetermined blowing angle and a temperature diffusibility while the louver is moved rotationally above the predetermined blowing angle are improved. Solving means: In an air conditioner in which a louver is provided at a blowing opening and said louver is moved rotationally from above to below or from below to above by a variable speed mechanism, at the time of heating, a louver rotational speed while the louver is moved rotationally in a range of a blowing angle &thetas;1 is set to a speed omega 1 within a vortices generation area relative to a wind velocity of blowing air flow and a louver rotational speed while the louver is moved rotationally over the blowing angle &thetas;1 is set to a speed omega 2 within a vortices non-generation area relative to the wind velocity of blowing air flow. Thereby, at the time of heating, a downward reachability in a room while the louver is moved rotationally below the predetermined blowing angle and a temperature diffusibility while the louver is moved rotationally above the predetermined blowing angle are improved. Further, an air conditioner in which, at the time of cooling, a uniformity of temperature distribution is improved is also provided.
