The invention relates to the technical field of air conditioners, in particular to a control method of an air conditioning system and the air conditioning system. The control method and the air conditioning system aim to solve the problems that the heat exchange efficiency of a refrigerant and chilled water in an existing air conditioner refrigeration system is low and the chilled water is likelyto be frozen. The invention provides the control method of the air conditioning system and the air conditioning system for solving the problem. The obtained actual evaporation temperature of a whole machine evaporator of the air conditioning system is compared with a preset temperature, and the evaporation temperature of the whole machine evaporator is adjusted based on the comparison result, so that when the evaporation temperature of the whole machine evaporator is maintained within a certain preset temperature scope, the evaporation efficiency of the whole machine evaporator is maintained at a high level, and the p
