Ventilation ducts are an important component of indoor environmental control, mainly used for conveying air, controlling indoor air quality, and maintaining temperature and humidity inside buildings. With the increasing demand for indoor environmental control, the application range of ventilation ducts is also expanding.

通風管道的材質一般有金屬、非金屬、塑料等。其中，金屬通風管道的主要特點是耐高溫、防腐、易清洗，通風效果好。但是，由于金屬通風管道的制造工藝復雜，成本較高，因此在一些低檔建筑中較少使用。非金屬通風管道一般采用玻璃纖維或其他合成材料制成，其特點是重量輕、抗腐蝕性好，但是不適用于高溫環境。塑料通風管道輕便、易安裝，但是其不耐高溫、易老化等缺點限制了其適用范圍。通風管道的安裝應注意以下幾點：通風管道在安裝前應進行清潔消毒處理，以保證管道內部無菌污染。

The materials of ventilation ducts generally include metal, non-metal, plastic, etc. Among them, the main characteristics of metal ventilation pipes are high-temperature resistance, anti-corrosion, easy cleaning, and good ventilation effect. However, due to the complex manufacturing process and high cost of metal ventilation ducts, they are less commonly used in some low-end buildings. Non metallic ventilation ducts are generally made of glass fiber or other synthetic materials, which are characterized by light weight and good corrosion resistance, but are not suitable for high-temperature environments. Plastic ventilation pipes are lightweight and easy to install, but their shortcomings such as low temperature resistance and easy aging limit their applicability. The installation of ventilation ducts should pay attention to the following points: Before installation, ventilation ducts should be cleaned and disinfected to ensure sterile contamination inside the ducts.

其次，安裝時應根據建筑物的結構和通風要求進行設計，盡量避免彎曲和拐角，以確保空氣流通暢通。安裝后應進行檢測和維護，定期清洗管道內部，保持其清潔衛生，以保證通風效果。總之，通風管道是室內環境控制不可缺少的組成部分，其合理的選擇和安裝對于室內環境的控制至關重要。隨著科技的發展，通風管道材質和安裝技術也在不斷升級，相信未來通風管道將會發揮更為重要的作用。

Secondly, the installation should be designed according to the structure and ventilation requirements of the building, avoiding bends and corners as much as possible to ensure smooth air circulation. After installation, inspection and maintenance should be carried out, and the interior of the pipeline should be cleaned regularly to maintain its cleanliness and hygiene to ensure ventilation effectiveness. In short, ventilation ducts are an indispensable component of indoor environmental control, and their reasonable selection and installation are crucial for controlling the indoor environment. With the development of technology, the material and installation technology of ventilation ducts are also constantly upgrading. It is believed that ventilation ducts will play a more important role in the future.
