送风口时,拆除出风口。取样应收集一定区域内风管表面积聚的所有灰尘,并将其完好地带出风管。通风管道污染度检查中风管积灰的检查设备、检查和分析方法与通风管道清洗后的清洁度检查相同。集中空调通风系统中通风管道内表面微生物和风管内表面细菌总数的检测方法
When the air supply outlet is opened, the air outlet shall be removed. The sampling shall collect all dust accumulated on the surface of the duct in a certain area and take it out of the duct in good condition. The inspection equipment, inspection and analysis method of dust accumulation in ventilation duct are the same as those after cleaning. Detection method of total number of microorganisms on the inner surface of ventilation duct and bacteria on the inner surface of air duct in central air conditioning ventilation system
