The invention provides an intelligent air-conditioner control method based on person information in an air-conditioning area. The intelligent air-conditioner control method comprises the following steps: S1, according to the minimum fresh air volume Moamini of VAVboxi connected with an AHU, calculating the total fresh air volume Moa of the AHU according to Moamini, wherein Moa=sigma Moamini; S2, according to Trai and Trseti, implementing dual PID control so as to obtain Dseti; S3, calculating the total air supply volume Msa of the HAU, and according to Dseti, performing static pressure PID control so as to obtain the total air supply volume Msa; S4, according to the ratio of Moa to Msa, adjusting the opening of a fresh air valve Voa. As dual PID control is performed according to Trai and Trset so as to obtain the opening Dseti of a tail end air valve, the comfort degree of the air-conditioning area under the VAVboxi control is increased; meanwhile the opening degree Voa of the fresh air valve is adjusted according to the ratio of Moa to Msa, the accuracy of fresh air control of the air-conditioning area under the VAVboxi control is improved.
