It doesn't matter whether there is a static pressure box or not. Generally speaking, it is an empty box to facilitate the connection of the machine room. According to the regulations, the cross-section flow rate is less than 2. In fact, it has no other function except the connection. If it is necessary to press the muffler. The air supply determines the wind speed and the size of the air supply outlet according to the air supply volume and installation position. The area of the return air outlet is determined according to the return air volume. The return air generally has a small wind speed of 2, and the length and width are determined according to the installation position. According to the above, select the type, and then calculate the wind resistance of the long pipe, as long as the static pressure outside the unit is small.

暖通工程是整個建筑工程的收尾工作，所以尾期工程一定要做到細致。無論是施工單位采購材料還是甲方供應材料，技術(shù)人員都要對其規(guī)格、型號、質(zhì)量進行全面嚴格檢查，對質(zhì)量檢查合格單、合格證件檢查不合格的不予進場，要求必須各項測驗報告符合國家技術(shù)標準和設計要求。防腐、保溫工程的質(zhì)量控制。要求保溫材料粘貼牢固、接口嚴密，隔氣防潮層要嚴密。水管、風管在穿墻、穿樓層處和技術(shù)縫處保溫層連續(xù)緊密，管道和作墊用的木條防腐要合格。
