| 摘 要： | 对三级生物安全实验室上、下两种排风方式的特点进行了研究。将实验与数值模拟相结合,根据实验数据修正数学模型,利用Fluent软件进行计算,重点对空气龄、换气效率、自净时间等评价指标进行了提取和处理,对两种气流组织方式的实验数据及计算结果进行了分析比较。结论是:相同情况下,上排风方式的室内平均空气龄和换气效率高于下排方式;二者自净时间相差不大。

| Abstract: | The article discourses upon the research on the air performance of the two exhaust mode in Level-3 Biosafety Laboratory. Combine the Experiment and numerical simulation, the researcher sets up and optimizes the mathematical model in the help of the experimental data. The computation is done with Fluent soft and the evaluation index data that contains age of air, air exchange efficiency and recovery time etc are picked up and processed. Based on the data, the article gives analyses and comparisons on the two air distribution modes and educes the conclusion: on the same conditions, the age of air and air exchange efficiency is better when using a ceiling exhaust; the self cleaning time is sameness of the two exhaust modes. |
