Control method of air conditioner, control system of air conditioner, and air conditioner

The invention provides a control method of an air conditioner, a control system of the air conditioner, and the air conditioner. The control method of the air conditioner comprises the following steps: after a fan of the air conditioner operates at a default rotational speed for preset time, judging whether the working mode of the air conditioner is a refrigeration mode or a heating mode; if the working mode of the air conditioner is judged to be the refrigeration mode, judging whether a difference value between an environment temperature sensing and measuring value of an environment temperature measuring device and a preset environment temperature value is smaller than a first temperature difference value or not; when the difference value of the environment temperature sensing and measuring value and the preset environment temperature value is smaller the first temperature difference value, controlling the fan of the air conditioner to operate according to the first rotational speed, wherein a first rotational speed is greater than or equal to the default rotational speed. Through the adoption of the technical scheme, temperatures of different positions in a room are more uniform through the air conditioner in the refrigeration mode or the heating mode, so that the comfort degree of a user during using the air conditioner is improved, and the user experience is further improved.
