非单向流洁净室需供给足够的通风量,以维持洁净室所要求的洁净度,因此通风量的合理确定是设计工作的重要环节。目前国内常见的理论计算式中虽然包括了一些相关制约因素,可以作为定性分析的参考,但在实际工程中往往难于运用,特别是以国内常见的理论计算式为依据来否定早期国外学者所推导的较为简约的理论式,更有欠妥当。通过一些例题分析试对相关问题进行了讨论。
Non-unidirectional flow clean room to provide adequate ventilation to maintain the cleanliness required by the clean room, so a reasonable determination of ventilation is an important part of the design work. At present, although the common theoretical calculation formulas in our country include some related constraints, which can be used as a reference for qualitative analysis, they are often difficult to be applied in practical projects. In particular, based on common domestic theoretical formulas, The more simple theoretical formula, more inappropriate. Through some examples of analysis of the relevant issues were discussed.
