The invention provides a wind speed frequency limiting control method for a direct current variable frequency air conditioner indoor unit. The wind speed frequency limiting control method comprises the step that according to the current operation mode of an air conditioner, a compressor is controlled to be operated on the basis of a frequency limiting protection scheme of the corresponding relation of the indoor unit preset wind speed and the maximum operational frequency. When the air conditioner is started, the maximum operational frequency, corresponding to the indoor unit preset wind speed, of the compressor is limited, so that the situation that the pressure of an air conditioner system is too high, the back pressure of the compressor is too high, and hiss noise and buzz noise occur in a room due to the fact that a user sets the preset wind speed of the indoor unit to be low, and the compressor of the air conditioner system operates at a high frequency is avoided, and the user experience is improved.
