　　通风管道工作原理

Working principle of ventilation ducts

　　通风管道的工作原理主要基于空气流动的原理，通过合理设置进风口和排风口，实现室内外空气的有效交换，进而改善室内空气质量，维持舒适的环境。具体来说，通风管道系统可以分为自然通风和强制通风两种。自然通风的原理是利用气流的重力差和气压差，使空气在进风口和排风口之间循环流动，实现室内空气的新鲜和污浊空气的排除。强制通风则是通过机械设备如风机、风量调节器等设备的协助，增加气流的速度和流量，强制性地将污浊空气排出，同时补充新鲜空气。

The working principle of ventilation ducts is mainly based on the principle of air flow. By reasonably setting the inlet and outlet, effective exchange of indoor and outdoor air is achieved, thereby improving indoor air quality and maintaining a comfortable environment. Specifically, ventilation duct systems can be divided into two types: natural ventilation and forced ventilation. The principle of natural ventilation is to use the difference in gravity and pressure of the airflow to circulate air between the inlet and outlet, achieving the elimination of fresh and polluted indoor air. Forced ventilation is achieved through the assistance of mechanical equipment such as fans, air volume regulators, etc., to increase the speed and flow of airflow, forcibly expel polluted air, and supplement fresh air.

　　管道风机的工作原理主要是基于离心式风机的工作原理。当电机旋转时，它带动叶轮一起旋转。由于叶轮的形状和旋转速度，叶片将空气从进口吸入，并沿着叶片的曲线将其加速，形成高速气流。这个高速气流被抛出叶轮，产生一个负压区域，使得周围的空气被吸入风机中。当电动机启动时，叶轮开始旋转，产生低压区和高压区。气流由高压区向低压区流动，通过管道传输到目标位置。

The working principle of pipeline fans is mainly based on the working principle of centrifugal fans. When the motor rotates, it drives the impeller to rotate together. Due to the shape and rotational speed of the impeller, the blades draw air in from the inlet and accelerate it along the curve of the blades, forming a high-speed airflow. This high-speed airflow is thrown out of the impeller, creating a negative pressure area, causing the surrounding air to be sucked into the fan. When the motor starts, the impeller begins to rotate, creating a low-pressure and high-pressure zone. The airflow flows from the high-pressure zone to the low-pressure zone and is transmitted to the target location through pipelines.

　　消防排烟管道的工作原理是通过排烟风机将污浊空气从室内吸入管道，然后将其排放建筑物外部。在火灾发生时，由于高温和浓烟的存在，烟道的一端会打开，烟雾开始从通风管道外部排出，并将室内的空气排放室外。

The working principle of the fire smoke exhaust duct is to draw polluted air from the indoor area into the duct through the smoke exhaust fan, and then discharge it to the outside of the building. When a fire occurs, due to the presence of high temperature and thick smoke, one end of the flue will open, and smoke will start to be discharged from the outside of the ventilation duct, releasing indoor air to the outside.
