Control method of heat exchange system, heat exchange system and computer readable storage medium

The invention discloses a control method of a heat exchange system, the heat exchange system and a computer readable storage medium. The control method comprises the steps that the preset refrigerating capacity range of an outdoor unit is obtained, and the preset heat extraction rate of each indoor unit is obtained; when any indoor unit meets the set shutdown condition, whether the set shutdown condition is not met and whether the sum of the preset heat extraction rates of the indoor units in operation exceeds the preset refrigerating capacity range of the outdoor unit or not is judged, if yes, the operation mode of the indoor units meeting the set shutdown condition is maintained, and if not, the operation mode of the indoor units meeting the set shutdown condition is maintained. And the indoor unit meeting the shutdown set condition is controlled to enter a shutdown mode. A user can be prompted whether the indoor unit and the outdoor unit are matched in type selection or not, meanwhile, the refrigeration ef
