Abstract: An in-room air conditioner adjustment method is provided and includes: obtaining a return air temperature detected by a temperature sensor corresponding to each air conditioner; adjusting, according to a difference between the obtained return air temperature and a temperature threshold, a fan rotational speed of each air conditioner until it is determined that an absolute value of the difference between the obtained return air temperature detected by the temperature sensor and the temperature threshold is less than a first specified value; determining that the absolute value of the difference between the return air temperature detected by the temperature sensor; and when an absolute value of a difference between fan rotational speeds of any two adjacent air conditioners is greater than a second specified value, adjusting a fan rotational speed of an air conditioner whose fan rotational speed is lower in the two adjacent air conditioners.
