摘要
在自然通风条件下,针对推拉半开窗,推拉落地窗,内开平开窗,内开上悬窗和内开下悬窗五种不同开启方式的窗户,对衡阳市典型住宅内的甲醛散发特性进行数值模拟。对比不同窗户开启方式下室内甲醛浓度的排放速率和浓度分布,分析得到采用内开平开窗方式的甲醛排放效果最为理想,且窗户的开启角度与室内甲醛排放速率呈正相关。住宅装修时选用开启面积较大的平开窗,定期将门窗最大角度开启,保证室内空气质量与人员健康。
Numerical simulation been taken to the formaldehyde emission characteristic in Hengyang city within typical residence under the condition of natural ventilation with half-sliding window,French sliding window,in-swinging casement window,top-hinged in-swinging window and bottom hung window.Compared to concentration of indoor formaldehyde emission rate and concentration distribution under different windows,the results show that in-swinging casement window has ideal discharge effect with formaldehyde emission,and the opening angle is positively correlated with indoor formaldehyde emission rate.It be helpful for the formaldehyde emission and assure indoor air quality and staff health when the residence is decorated to choose windows with larger area,and open the maximum angle of door and window regularly.
