摘要
通过理论计算,提出针对不同控制粒径,在换气次数、过滤器选择等方面应采取不同的合理措施。并分析了现行规范中推荐的换气次数适用条件,纠正了实际工程中几个常见的错误认识。
Reasonable measures were taken regarding air change rate and filter selection to control different particle sizes based on theoretical calculations. The applicable conditions of air change rate recommended in current standards were analysed. The misunderstandings usual in actual projects were corrected.
