通风管道主要作用包括：

　　The main functions of ventilation ducts include:

　　空气流通 ：通风管道帮助室内空气流通，确保人们可以呼吸到新鲜空气，同时排出污浊空气。

　　Air circulation: Ventilation ducts help circulate indoor air, ensuring that people can breathe fresh air while expelling polluted air.

　　降低有害物质浓度 ：通过通风，可以降低室内空气中有害物质的浓度，如工厂中的有害物质经过处理后排出室外，再引入新鲜空气。

　　Reduce the concentration of harmful substances: By ventilation, the concentration of harmful substances in indoor air can be reduced. For example, harmful substances in factories can be treated and discharged outside before introducing fresh air.

　　维持氧气供应 ：通风管道确保室内有足够的氧气供应，维持人的生命活动。

　　Maintain oxygen supply: Ventilation ducts ensure sufficient oxygen supply indoors to sustain human life activities.

　　控制气流速度 ：通风管道可以调节气流速度，缓解因空气不流通造成的窒息感。

　　Control airflow speed: Ventilation ducts can adjust airflow speed to alleviate suffocation caused by poor air circulation.

　　节能环保 ：通风管道可以通过调节通风口的大小和位置，合理利用自然风力或机械通风设备，达到节能效果。

　　Energy saving and environmental protection: Ventilation ducts can achieve energy-saving effects by adjusting the size and position of ventilation openings, making reasonable use of natural wind or mechanical ventilation equipment.

　　防火安全 ：在设计和制造过程中，通风管道考虑了防火性能，有助于防止火灾蔓延。

　　Fire safety: In the design and manufacturing process, ventilation ducts consider fire resistance, which helps prevent the spread of fire.

　　适应不同需求 ：通风管道可以根据建筑结构和需求进行设计和布置，满足不同场所的通风需求。

　　Adapt to different needs: Ventilation ducts can be designed and arranged according to building structure and requirements to meet the ventilation needs of different places.

　　结构稳固可靠 ：通风管道通常由耐腐蚀、耐高温材料制成，结构稳固，连接紧密，安全可靠。

　　Stable and reliable structure: Ventilation ducts are usually made of corrosion-resistant and high-temperature resistant materials, with a stable structure, tight connections, and safety and reliability.

　　应用广泛 ：通风管道在楼房建筑、工厂、商业空间等多个领域都有广泛应用。

　　Widely used: Ventilation ducts are widely used in various fields such as building construction, factories, and commercial spaces.

　　其他作用 ：除了基本的通风功能，通风管道还可以用于排烟、排湿、排热等，改善室内空气质量。

　　Other functions: In addition to its basic ventilation function, ventilation ducts can also be used for smoke exhaust, moisture removal, heat dissipation, etc., improving indoor air quality.
