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。
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.
