AI summary

The present disclosure provides a method and device for position determination, an air conditioning system, and a readable storage medium. The method for position determination includes: acquiring return air temperature information of each indoor unit; determining a first correlation coefficient between every two indoor units based on the return air temperature information; classifying indoor units based on the first correlation coefficient to obtain a number of classified groups; and generating relative position information in each classified group based on the first correlation coefficient by taking any one of the indoor units as a locating point. Maintenance personnel are not required to manually maintain a relative position relation of indoor units. Therefore, the maintenance difficulty of the relative position relation of indoor units is reduced, and a time cost and a labor cost required for maintenance are reduced accordingly.
