摘要 基于所建的污染物散发模型,分析了室内温度、传质系数、换气次数对多孔材料污染物散发的影响。结果显示,室内温度对材料内污染物散发的影响非常明显,温度越高,污染物散发时间越短;提高传质系数不能显著加速污染物散发,而降低该值却可以抑制污染物的释放;换气次数对污染物散发影响很小,但可以通过改变换气次数来控制室内污染物浓度。 Based on a contamination emission model, analyses the influences of indoor temperature, mass transfer coefficient and air changes on contamination emission from porous materials. The results show that the influence of indoor temperature is very obvious and the higher temperature is, the shorter emission time is; increasing mass transfer coefficient can not apparently accelerate contamination emission but reducing the coefficient can restrain contamination emission; the influence of air changes is obscure but indoor contamination concentration can be controlled by changing air changes.
