1、 Slight damage

如果通風管道在實際應用中出現破損，但是并不嚴重，則可以使用膠帶等密封材料展開修護，如果位置在管道表面，則可以使用修補膠展開處理，如果破損部位在鋁箔層，則可以使用鋁箔層對其展開處理。以上處理方式只能對通風管道的輕微破損有用。

If the ventilation pipe is damaged in practical application, but it is not serious, it can be repaired with sealing materials such as adhesive tape. If it is located on the pipe surface, it can be repaired with repair adhesive. If the damaged part is in the aluminum foil layer, it can be expanded with aluminum foil layer. The above treatment method can only be used for slight damage of ventilation pipe.

二、板材更換

2、 Plate replacement

如果通風管道中的保溫纖維出現破損，則需要在管道破損部位預留出一定的搭接口，根據實際通風管道板材的類型，對位置展開切割以及密封修 復等。

If the insulation fiber in the ventilation pipe is damaged, a certain lap joint should be reserved at the damaged part of the pipe. According to the type of the actual ventilation pipe plate, the position should be cut and sealed for repair.

三、管道更換

3、 Pipe replacement

這種修 復方式適合應用在通風管道破損較為嚴重的情況，需要對管道在破損的地方展開管道更換。

This kind of repair method is suitable for the situation that the ventilation pipeline is seriously damaged, and the pipeline needs to be replaced in the damaged place.

四、通風管道性能檢測

4、 Performance test of ventilation duct

為了保證通風管道的實際應用質量，需要對其展開性能檢測，在此過程中，需要對通風管道的影響因素、工藝流程以及需要的設備展開控制，保證通風管道施工中的每個環節都能夠符合相應的質量要求，達到提升通風管道在暖通空調工程應用質量的目的，促進我國暖通空調工程的發展。

In order to ensure the practical application quality of the ventilation pipeline, it is necessary to carry out the performance test. In this process, it is necessary to control the influencing factors, process flow and required equipment of the ventilation pipeline, so as to ensure that each link in the construction of the ventilation pipeline can meet the corresponding quality requirements, and achieve the purpose of improving the application quality of the ventilation pipeline in the HVAC engineering, Promote the development of HVAC engineering in China.
