An indoor air-conditioning unitwhich can effectively deactivate allergens includes an intake grillfor drawing in indoor air. Indoor heat exchangers, andexchange heat between air drawn in from the intake grilland a refrigerant to thereby cool or heat the air. A diffuserreturns the air which has been heat-exchanged with the indoor heat exchangers, back into the room. A cross-flow fanblows air which has been drawn in from the inlet and heat exchanged from the diffuserinto the room. An allergen deactivation filteris arranged in an internal spacethrough which the air flows and supports an allergen deactivation enzyme. An enzyme activation device maintains the internal space S in an atmosphere for activating the allergen deactivation enzyme.

An air conditioner is provided and includes a louver which is provided at a blowing opening. The 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 .theta..sub.1 is set to a speed .omega..sub.1 within a vortices generation area relative to a wind velocity of blowing air flow. Also, a louver rotational speed while the louver is moved rotationally over the blowing angle .theta..sub.1 is set to a speed .omega..sub.1 within a vortices non-generation area relative to the wind velocity of blowing air flow. Thereby, at the time of heating, downward reach of warm air 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.
