摘　　要：文章运用Fluent软件,研究了不同送风速度下办公室内细颗粒物的流动特点。通过建立颗粒流动模型计算得出不同送风速度下室内PM_(2.5)颗粒浓度分布的特征,分析了员工工作区域的最佳送风参数,以减少颗粒物对人员身体健康的影响。计算四种不同工况及不同送风速度下室内空气流场和颗粒浓度的分布,对比分析表明,最佳工作条件为送风速度3.25 m/s,送风温度295 k。计算结果为今后空调工程施工中的供气参数设置提供一定的理论参考。This paper uses Fluent software to study the flow characteristics of fine particles in the office under different air supply speeds.Through the establishment of particle flow model,the characteristics of indoor PM_(2.5) particle concentration distribution under different air supply speeds are calculated,and the optimal air supply parameters of employees’ working areas are analyzed to reduce the impact of particles on personnel’s health.The distribution of indoor air flow field and particle concentration under four different working conditions and different air supply speeds are calculated.The comparative analysis shows that the best working conditions are air supply speed of 3.25 m/s and air supply temperature of 295 K.The calculation results provide a certain theoretical reference for the setting of gas supply parameters in the construction of air conditioning projects in the future.
