摘要
本文建立了一个典型的地下空间模型,在三种不同的送回风方式下进行了室内氡浓度场的模拟。结果表明,回风口的位置对室内的氡浓度场有很大的影响,应当将其放置于氡气散发较为集中的位置,避免高浓度氡气与人员呼吸区的空气混合。
With a typical underground space model, the concentration field of radon under three different modes of air supply and return had been simulated. The result shows that the location of return air intake has a great effect on the indoor radon concentration field, and it should be laid at the radon emission source, which the mixing of the radon in high concentration and the air in breathe area can be avoided.
