Variable refrigerant flow air conditioning system, control method thereof, and computer-readable storage medium

A method for controlling a variable refrigerant flow (VRF) air conditioning system, comprising:

• obtaining indoor units in an operating state in response to that the VRF air conditioning system is cooling;
• obtaining indoor units with humidity demand and indoor units without humidity demand among the indoor units in the operating state;
• determining a ratio of humidity demand according to an output nominal value of each indoor unit in the operating state, wherein the ratio of the humidity demand comprises a ratio of a total output nominal value of the indoor units with humidity demand to a total output nominal value of the indoor units without humidity demand, or the ratio of the humidity demand comprises a ratio of the total output nominal value of the indoor units with humidity demand to the total output nominal value of the indoor units with humidity demand and the indoor units without humidity demand;
• and
• in response to that the ratio of the humidity demand is greater than a preset ratio, adjusting a rotation speed of an outdoor fan according to an outdoor environment temperature and/or adjusting a frequency of a compressor according to a preset humidity corresponding to the indoor unit in the operating state.
