The invention provides a flow distribution control method for a central flue system of a high-rise building. According to the flow distribution control method, the central flue system comprises indoorunits mounted on different floors; air outlets of all the indoor units communicate with a public flue through respective smoke tubes; flow velocity detecting modules or pressure detecting modules aremounted on the smoke tubes; and the target flow QL is preset within the target range of [Qx, Qd]. The flow distribution control method comprises a slave control method and a host control method. Theflow distribution control method has the advantages that the actual flow or outlet pressure situation of an existing range hood can be detected by utilizing the flow or pressure detecting module mounted at the outlet end of the range hood, and then whether the motor rotating speed or gear position of the existing range hood needs to be increased or decreased so as to achieve the control of flow can be determined; by the adoption of the entire control method, the basic guarantee of effective air volume can be achieved, and the difference among the smoke discharging effects of different floors can be eliminated; furthermore, the control can be achieved through the frequency conversion or gear shift function of the indoor range hood; and the control process is relatively efficient, energy-saving and relatively low in loss.
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档位实现流量控制，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。
