The invention discloses a flow distribution control method of a central flue system of a high-rise building. The central flue system comprises indoor units installed on different floors, an air outletof each indoor unit communicates with a common flue through a respective smoke pipe, and a target flow QL is preset to be within a target range [Qx, Qd]. The flow distribution control method of the central flue system of the high-rise building has the advantages that ensors such as power, current, pressure, flow speed and the like are not needed, only the current gear and the current rotating speed need to be fed back, the current gear and rotating speed detection or back electromotive force is utilized for calculating the rotating speed, then the one-to-one correspondence relationship between the rotating speed and the flow under the same gear is utilized for calculating the current actual flow, the difference between the current actual flow and the target flow is calculated, at least one gear is selected to be adjusted, and whether the flow can be controlled in a flow range is calculated. The whole control method can realize the basic guarantee of effective air quantity, eliminate the difference of smoke exhaust effects of different floors, and through the frequency conversion or gear shift control of an indoor range hood, the control process is efficient and saves energy, and loss is low.
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，预先设定目标流量QL在目标范围[Qx,Qd]内，本发明的优点在于：该高层楼宇的流量分配控制方法不需要功率或者电流及压力、流速等传感器，只需要能反馈当前档位和转速，利用当前档位转速检测或者反电动势计算转速，然后利用同档位下转速与流量的一一对应关系，计算出当前实际流量，计算与目标流量的差异，选择调整至少一个档位，计算能否控制到流量范围内，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。
