办公建筑中木制品材料散发VOC的研究

Numerical approach of VOC emissions from wood products in office buildings

现代办公建筑中的房间内大都使用木地板进行装修并配有办公桌等木制品家具,这些材料在使用中长期散发低浓度挥发性有机物(VOC),从而影响室内空气质量。用三维紊流数值模拟的方法,对有VOC散发源房间采用不同的送风方式下的室内VOC浓度分布情况进行了分析。结果发现,不同的通风方案造成的VOC浓度分布是不一样的。推荐较好的通风方案,可供设计人员参考。

Some dry materials such as wood products are widely used in office buildings. These materials of low emission source emit a variety of volatile organic compounds （VOC） in long-term emission process so as to influence indoor air quality. The author analyzes and reckons several concentration distribution on VOC emission that correspond with different air current arrangements by numerical simulation in three dimensions, and finds out that different ventilated conditions will make different concentration distributions. Moreover a better design for the designer is recommended in the end.
