Wind speed control method, device and equipment, medium and air conditioner thereof

The invention provides an air speed control method, device and equipment, a medium and an air conditioner thereof. The method comprises the steps that the air speed of the air conditioner is adjusted to a first air inlet speed according to the exhaust speed; under the condition that the indoor oxygen concentration is larger than or equal to the expected oxygen concentration, the actual standard reaching time is determined; according to the oxygen generation speed, the expected standard reaching time and the actual standard reaching time, the oxygen consumption speed is calculated; the air conditioner air speed is adjusted to the second air inlet speed; the expected standard reaching time is the time when the expected oxygen concentration is reached under the condition that no person is in the room, and the actual standard reaching time is the time when the expected oxygen concentration is actually reached under the condition that the person is in the room. The indoor oxygen consumption speed is determined acc
