通常使用鍍鋅風(fēng)管，不銹鋼管用于腐蝕性和特別潮濕的地方。當環(huán)境空氣濕度較高時，風(fēng)道外壁應(yīng)進行防腐防銹處理。輸送高溫高濕的風(fēng)道內(nèi)壁應(yīng)噴涂磷化底漆或其他防腐涂料。當風(fēng)道輸送高溫氣體或低溫空氣時，風(fēng)道外壁應(yīng)進行保溫（冷保）處理。

Galvanized air ducts are usually used, while stainless steel pipes are used in corrosive and particularly humid areas. When the ambient air humidity is high, the outer wall of the air duct should be treated with anti-corrosion and rust prevention. The inner wall of the air duct conveying high temperature and high humidity should be sprayed with phosphating primer or other anti-corrosion coatings. When the air duct transports high-temperature gas or low-temperature air, the outer wall of the air duct should be insulated (cold preserved).

輸送高溫氣體的風(fēng)道的隔熱目的是防止管道中空氣的熱量損失（冬季出現(xiàn)在集中式空調(diào)系統(tǒng)中）。在輸送廢熱蒸汽或高溫氣體時，為了防止熱量傳遞到室內(nèi)并使室溫升高，可以防止人再次接觸風(fēng)管并燙傷。在夏季，當輸送氣體的溫度低于周圍環(huán)境的空氣露點溫度時，通風(fēng)管道外壁會產(chǎn)生冷凝現(xiàn)象?？照{(diào)系統(tǒng)的空氣管道會增加冷卻損失，冷凝水滴會污染天花板和墻壁地板。因此，還應(yīng)進行冷卻和隔熱處理。

The insulation purpose of the air duct transporting high-temperature gas is to prevent heat loss of the air in the pipeline (which occurs in centralized air conditioning systems in winter). When transporting waste heat steam or high-temperature gas, in order to prevent heat from being transferred indoors and raise the room temperature, it is possible to prevent people from coming into contact with the air duct again and getting burned. In summer, when the temperature of the transported gas is lower than the dew point temperature of the surrounding air, condensation will occur on the outer wall of the ventilation duct. The air ducts of the central air conditioning system will increase cooling losses, and condensation droplets will contaminate the ceiling and walls and floors. Therefore, cooling and insulation treatment should also be carried out.

以上是通風(fēng)管道防腐保溫的原因。只有防腐才能減少后期使用中的腐蝕，所以我們應(yīng)該注意這些方面，并盡量保證在以后使用時更光滑，效果更好。

The above are the reasons for the anti-corrosion and insulation of ventilation ducts. Only anti-corrosion can reduce corrosion in later use, so we should pay attention to these aspects and try to ensure smoother and better results in future use.
