If the target air supply quantity in the current state is smaller than the maximum air supply quantity of the main air inlet, judging the relation between the current air supply quantity of the main air inlet and the target air supply quantity, if the current air supply quantity of the main air inlet is smaller than the target air supply quantity, sending an opening-reducing instruction to the main air inlet to reduce the opening of the main air inlet, and if the current air supply quantity of the main air inlet is larger than the target air supply quantity, sending an opening-increasing instruction to the main air inlet to increase the opening of the main air inlet. Therefore, the air supply adjusting method provided by the invention can adjust the opening quantity and opening size of the air supply outlets according to the target air supply quantity, so that the air speed of the air outlets can be kept constant when the air supply quantity is changed, when a plurality of air supply outlets are arranged, the air supply quantity matching and adjusting among the air outlets are realized, the air outlet speed of each air supply outlet is approximately constant on the premise of ensuring the proper air supply quantity, the distribution requirements of indoor airflow organization, airflow field and temperature field are met, and the use comfort of the air conditioner is improved.
