Ventilation pipeline engineering refers to a series of projects carried out to ensure indoor air quality and comfort, conveying fresh air indoors or expelling polluted air outdoors. Ventilation pipeline engineering usually includes knowledge in the following aspects:

通風系統設計：通風系統設計需要根據建筑物的使用功能、人員密度、空氣污染程度等因素進行評估和計算。設計過程中需要確定通風系統的空氣流量、送風溫度、換氣次數等參數，并選擇合適的通風設備和管道布局。

Ventilation system design: Ventilation system design needs to be evaluated and calculated based on factors such as building functionality, personnel density, and air pollution level. During the design process, it is necessary to determine the air flow, supply air temperature, Air changes per hour and other parameters of the ventilation system, and select appropriate ventilation equipment and pipeline layout.

通風設備：通風設備包括送風機、排風機、空調設備等。這些設備選型需要考慮空氣流量、靜壓損失、噪音控制等因素，并符合相關的規范和標準。

Ventilation equipment: Ventilation equipment includes supply fans, exhaust fans, air conditioning equipment, etc. The selection of these equipment needs to consider factors such as air flow rate, static pressure loss, noise control, and comply with relevant specifications and standards.

通管道材料：通風管道通常采用金屬材料如鍍鋅鋼板、不銹鋼板等，也可以使用塑料材料如氯乙烯（PVC）管道。材料的選擇需考慮氣流速度、防腐性能、節能效果等因素。

Material of ventilation pipes: Ventilation pipes are usually made of metal materials such as galvanized steel plate, stainless steel plate, etc., and plastic materials such as vinyl chloride (PVC) pipes can also be used. The selection of materials needs to consider factors such as airflow speed, anti-corrosion performance, and energy-saving effects.

4.道布局與連接：通風管道的布局應合理并盡減小阻力，以提高通風效果。在布局中需注意避開障礙物，合理設置彎頭、分支管道等，并證管道的連接緊密、無滲漏。

4. Layout and connection of ventilation ducts: The layout of ventilation ducts should be reasonable and minimize resistance to improve ventilation efficiency. In the layout, attention should be paid to avoiding obstacles, reasonably setting elbows, branch pipes, etc., and ensuring that the pipes are tightly connected and leak free.

通風系統試與運行：通風系統安裝完畢后需要進行調試和檢測，確保各項參數與設計要求一致。運行過程需要定期維護和清潔通風設備和管道，及時排除故障并保持系統的正常運行。

Ventilation system trial and operation: After the installation of the ventilation system, it is necessary to conduct debugging and testing to ensure that all parameters are consistent with the design requirements. The operation process requires regular maintenance and cleaning of ventilation equipment and pipelines, timely troubleshooting, and maintaining the normal operation of the system.

以上是通風管工程相關的一些知識點，具體實施中還需根據不同建筑物的特點和要求進行具體設計和施工

The above are some knowledge points related to ventilation pipe engineering, and specific design and construction should be carried out according to the characteristics and requirements of different buildings during the implementation
