摘要
本文根据《洁净厂房设计规范》GBJ-73-84中不同级别乱流洁净室推荐的换气次数,计算了推荐换气次数下室内允许的单位容积发尘量。针对实际工程设计中换气次数计算和查图比较复杂这一问题,提出了一个简化的换气次数计算公式。
The paper quotes the recommended air-change rates for different grade turbulent flow clean rooms by《Design Regulation for Glean Room Facilities》OBJ-73-84, makes out the room allowed dust generation volume per-unit space under recommended air-change rates. Taking for the problem that air-change rate calculation and chart-using are complex in real engineering designings, the paper issues simplified formulas for airchange rate calculation.
