The invention relates to the technical field of anti-freezing of air conditioners, and particularly provides an anti-freezing control method of an air conditioning system. The problem that the heat exchange effect is affected due to the fact that an existing water-cooling air conditioning system is difficult to accurately judge the entering time and the exiting time of an anti-freezing mode is solved. Therefore, the air conditioning system comprises a refrigerant circulation loop and a heat exchange water way, a heat exchanger is arranged on the refrigerant circulation loop, and the refrigerant circulation loop and the heat exchange water way can exchange heat through the heat exchanger; according to the anti-freezing control method, the air conditioning system can be selectively controlled to enter the anti-freezing mode through the temperature before the refrigerant enters the heat exchanger and the temperature after the refrigerant flows out of the heat exchanger; and further selectively controlling the ai
