The invention discloses a flow distribution control method of a high-rise building central flue system. According to the flow distribution control method, the central flue system comprises indoor units installed on different floors, an air outlet of each indoor unit communicates with a public flue through a corresponding smoke pipe, a flow speed detection module or a pressure detection module is installed on each smoke pipe, and target flow QL is preset within a target range [Qx, Qd]; and the flow distribution control method comprises a slave control method and a host control method. The flowdistribution control method has the advantages that the flow speed detection modules or the pressure detection modules at the outlet ends of extractor hoods are used for detecting current actual flowor outlet pressure condition of the extractor hoods, and whether the current rotating speed or gear of motors of the extractor hoods is increased or decreased or not is determined to achieve flow control; and according to the whole control method, basic guarantee of effective air volume can be achieved, the smoke exhaust effect difference of different floors is eliminated, and meanwhile through frequency conversion or gear shifting control over the indoor extractor hoods, the control process becomes efficient, and energy saving and low loss can be achieved.
一种高层楼宇中央烟道系统的流量分配控制方法，中央烟道系统包括安装在不同楼层的室内机，每台室内机的出风口均通过各自的烟管与公用烟道相连通，在烟管上安装有流速检测模块或者压力检测模块，预先设定目标流量QL在目标范围[Qx,Qd]以内，流量分配控制方法包括从机控制方法和主机控制方法。本发明的优点在于：该高层楼宇的流量分配控制方法利用吸油烟机出口端带的流速或者压力检测模块，探测当前吸油烟机实际流量或者出口压力情况，决定是否提高或者降低当前吸油烟机电机转速或者挡位实现流量控制，整个控制方法能实现有效风量的基本保障、消除不同楼层排烟效果差异，且通过室内吸油烟机的变频或者换挡控制，控制过程较为高效、节能，损耗较少。
