| 摘 要： | 采用Airpak软件模拟研究在通风速率、源项强度和源项面积多因素作用下的室内甲醛扩散规律。结果表明,在室内甲醛初始为零时,源项散发甲醛后,在2000 s内室内甲醛浓度升高较快,之后处于平衡状态。在通风速率加倍时甲醛最高浓度降低56%,源项强度减半时甲醛最高浓度降低16%,源项散发面积减少37%时甲醛最高浓度降低24%。说明通风速率对室内甲醛浓度的影响最大,其次依次为源项散发面积和源项强度。

| Abstract: | The influences of ventilation velocity,source intensity and emission area on indoor formaldehyde diffusion law were researched by Airpak software simulation.Results showed that in 2000 seconds,formaldehyde concentration increased quickly from initial concentration of 0 mg/m 3,then reached to balance.When the ventilation velocity doubled,the maximum concentration of formaldehyde decreased by 56%,as the source intensity decreased by half,the maximum concentration decreased by 16%,while the source emission area decreased by 37%,the maximum concentration reduced by 24%.It concluded that the ventilation velocity had the greatest impact on formaldehyde concentration,the next was emission areas,and the source intensity had the least influence. |
