Air conditioner and air speed control method thereof

The invention discloses an air conditioner and a air speed control method thereof. Air scattering plates are arranged at the air outlet of an indoor unit so that the air outlet speed of the indoor unit can be decreased. Air guide plates are arranged so that the air outlet direction of the indoor unit can be regulated. The method includes the following steps that when the air conditioner runs in a refrigeration mode, if a non-air-feeling control instruction is received, the air conditioner is controlled to enter a non-air-feeling running mode; T0 is judged by detecting the human body surface temperature T0; if T0 is larger than the first preset temperature Tth, the air scattering plates are controlled to swing, or the air guide plates are controlled to move upwards, and the rotating speed of an indoor draught fan is controlled to be smaller than or equal to the first preset rotating speed; and if T0 is smaller than or equal to the Tth, the air scattering plates are controlled to be closed, the air guide plates are controlled to be opened to the preset air outlet angle, and the rotating speed of the indoor draught fan is controlled to be smaller than or equal to the second preset rotating speed. By means of the air conditioner and the air speed control method of the air conditioner, the comfortable temperature environment can be provided, and meanwhile the comfortable indoor air speed environment can be provided and comfort is improved.
