室内外气压平衡装置过风管施工技术

Construction Technology of Air Duct for Indoor and Outdoor Pressure Balancing Device

以某办公楼为例,对室内外气压平衡装置过风管施工技术进行研究,综述了通过在门顶设置室内外气压平衡装置(过风管道、孔口百叶、管道内隔音装置),消除门启闭时所产生空气正负压,使室内外气压保持平衡,并通过管内粘贴玻纤毡复合玻璃棉板和设置橡皮阀,以消除风管运行产生的噪音,减少风管壁的冷能量损失,并起到隔音效果。

Taking an office building as an example,the construction technology of the air duct of the indoor and outdoor air pressure balancing device is studied,and the paper summarizes that by setting the indoor and outdoor air pressure balancing device(air duct,orifice louvage and sound insulation device in the pipeline)on the top of the door,the positive and negative air pressure generated when the door is opened and closed can be eliminated,so that the indoor and outdoor air pressure can be balanced,and the glass fiber felt composite glass wool board and rubber valve are pasted in the pipe.To eliminate the noise generated by the operation of the air duct,reduce the loss of cold energy on the wall of the air duct,and play a sound insulation effect.
