The invention relates to a method for calculating fresh air volume of a single-channel multi-partition variable-air-volume air conditioner. The fresh air volume calculation idea of the system comprises: (1) the per capita fresh air volume and the unit area fresh air volume of each partition are determined; calculating the fresh air demand of the system; (2) calculating regional fresh air volume according to concepts of a respiratory region, regional air distribution efficiency and the like; and (3) calculating the fresh air volume of the multi-partition system according to the concepts of regional ventilation efficiency, critical ventilation partition, system ventilation efficiency and the like. Two methods for calculating the fresh air volume exist all the time: one method is to take thehighest fresh air ratio in each subarea as the system fresh air ratio, so that the fresh air volume of the ventilation subarea is large, and the fresh air energy consumption is increased; In another method, the fresh air dema
