摘要
设计师可利用CFD软件对建筑通风系统设计进行调整优化,这对节能减排、提高建筑的室内环境品质起到至关重要的作用。基于Airpak软件,选用室内零方程湍流模型对夏季空调训练馆内热环境进行数值模拟,可得到室内气流组织下的流场、温度场分布、PMV、PPD舒适度等指标。模拟结果表明对于小型体育训练场馆,上送上回形式相比侧送上回的气流组织形式,可以获得更为舒适的室内环境。室内零方程湍流模型能准确快速模拟空调通风房间气流组织分布,对空调系统的室内环境设计具有重要的指导意义。
Designers use CFD software to adjust and optimize the building ventilation system design,which plays an important role in energy saving and emission reduction and indoor air quality improvement.Based on Airpak software, indoor zero - equation turbulence model is selected to simulate the thermalenvironment of air - conditioned training hall in summer, and it can get velocity vector distribution,temperature field distribution, PMV, PPD comfort and other indicators under indoor airflow organization.The simulation results show that compared to the supplying from side, supplying from topcan obtain morecomfortable indoor environment for small sports training hall. The indoor zero - equation turbulence modelcan accurately and quickly simulate the distribution of air flow in the air - conditioned ventilation room,which has an important guiding significance for the indoor environment design of the air - conditioningsystem.
