中文摘要: |
对某公共建筑在自然通风情况下的室内环境进行数值模拟。根据 k-ε 湍流模型的控制方程及当地最多
风向、基本风速等因素对该建筑在自然通风情况下的夏季和过渡季室内环境进行数值模拟。得出:夏季及过
渡季时,室内空气分布比较均匀,空气流动死角区域小,换气次数大于 16 次 /h 的房间面积占比达到 95%,风
速变化较小,且新风量较大,室内空气品质较好;在过渡季,由于自然通风充分,室内主要功能区域温度基
本在 22℃左右。该建筑室内环境达到了绿色建筑的评价标准,可以为绿色建筑的规划和设计提供参考。

英文摘要: |
The indoor environment of a public building under natural ventilation is simulated numerically. According to the control
equation of the k-ε turbulence model,the most local wind direction, basic wind speed and other factors, numerical simulation of
the indoor environment of the building in summer and transition season under natural ventilation. It is concluded that in summer and
transition seasons, the indoor air distribution is relatively uniform, the dead area of air flow is small, room area with more than 16
air changes/h accounted for 95%, wind speed change is small, and fresh air volume is large, indoor air quality is better; In the
transition season, since sufficient natural ventilation, the indoor temperature substantially major functional areas about 22 ℃ . The
indoor environment of the building has reached the evaluation standard of green building, which can provide reference for the planning
and design of green building. |
