The invention discloses an air conditioning system and an air purification control method for an air conditioner. The air conditioning system comprises an air supply duct, a sterilization module, an air return duct, an air detection module, an exhaust duct, a fresh air duct, an environment quality detection module, a first air valve, a second air valve and a third air valve. The method comprises the steps that when the environment quality detection module detects that a CO2 concentration and a PM2.5 concentration in the fresh air duct are smaller than a CO2 concentration and a PM2.5 concentration, detected by the air detection module, in the air return duct, and smaller than a CO2 value and a PM2.5 value preset in an air treatment space, the first air valve is controlled to be opened; and when the environment quality detection module detects that the CO2 concentration and the PM2.5 concentration in the fresh air duct are larger than the CO2 concentration and the PM2.5 concentration, detected by the air detect
