The position of the reserved holes in the building structure shall be correct, and the holes shall be more than 100mm outside the air duct. The connection interface between the building structure air duct and the air duct shall be inserted along the air flow direction, and sealing measures shall be taken. The flexible short pipe with a length of 150~300 mm shall be set at the place where the air duct connects with the fan, fan housing, air processor and other equipment, or set according to the design regulations. Flexible stub pipes shall not be used as alignment and leveling pressure reducing connecting pipes. The length of the flexible short pipe at the structural deformation joint shall be more than 100mm wider than the width of the deformation joint, and the installation slope of the air duct conveying condensate or water vapor shall meet the design requirements. Longitudinal joints shall not be set at the bottom of the air duct, and the air duct joints shall be sealed.

2、管道法蘭的連接

2. Connection of pipe flange

對于襯墊材料，不得使用厚紙、紙板、石棉繩、鉛麻和油氈紙。墊圈材料應(yīng)盡量減少接頭。墊片材料的接頭應(yīng)采用梯形或榫頭連接，并應(yīng)粘接牢固。法蘭被均勻壓縮后，墊片材料的寬度應(yīng)與風(fēng)道內(nèi)壁齊平。風(fēng)管與潔凈室天花板、隔墻和其他圍護結(jié)構(gòu)之間的接縫應(yīng)緊密。

For gasket materials, thick paper, cardboard, asbestos rope, lead hemp and linoleum paper shall not be used. Gasket material shall minimize joints. The joints of gasket materials shall be connected by trapezoid or tenon, and shall be firmly bonded. After the flange is uniformly compressed, the width of the gasket material shall be flush with the inner wall of the air duct. Joints between air ducts and clean room ceilings, partitions and other enclosures should be tight.

3、風(fēng)管系統(tǒng)應(yīng)有良好的接地措施

3. The air duct system shall have good grounding measures

穿過輔助生產(chǎn)室要嚴密，不得設(shè)置接口。輸送空氣溫度高于80℃時，風(fēng)管應(yīng)按設(shè)計規(guī)定采取保護措施。風(fēng)管測量孔應(yīng)設(shè)置在便于測量和觀察的位置；天花板風(fēng)管上的測量孔應(yīng)留出相應(yīng)位置的活動天花板或檢查門。當(dāng)隔熱風(fēng)管采用金屬法蘭和金屬加強件時，外露部分應(yīng)采取措施防止冷橋冷凝。

Passing through the auxiliary production room shall be tight and no interface shall be set. When the conveying air temperature is higher than 80 ℃, protective measures shall be taken for the air duct according to the design provisions. The air duct measuring hole shall be set at the position convenient for measurement and observation; The measuring hole on the ceiling duct shall be reserved with a movable ceiling or inspection door at the corresponding position. When metal flanges and metal reinforcements are used for heat insulation air duct, measures shall be taken for exposed parts to prevent cold bridge condensation.

4、風(fēng)管系統(tǒng)應(yīng)檢查是否漏氣

4. The air duct system shall be checked for air leakage

這是安裝空調(diào)的環(huán)節(jié)，但也是一個重要的環(huán)節(jié)，所以業(yè)主在接受空調(diào)時一定不能忽視這一環(huán)節(jié)，在風(fēng)管安裝完成后，應(yīng)仔細檢查，防止漏風(fēng)。

This is the link of installing the air conditioner, but it is also an important link, so the owner must not ignore this link when accepting the air conditioner. After the installation of the air duct, it should be carefully checked to prevent air leakage.

5、風(fēng)管維護常識

5. Common sense of air duct maintenance

風(fēng)管安裝后，暫時未安裝的風(fēng)管開口、過濾器開口等開口部位應(yīng)及時用塑料布妥善包裹，防止現(xiàn)場灰塵進入清潔后的風(fēng)管，造成風(fēng)管二次污染。

After the installation of air duct, the openings of air duct and filter that are not installed temporarily shall be properly wrapped with plastic cloth in time to prevent dust from entering the cleaned air duct and causing secondary pollution of the air duct.
