摘要(Abstract):

会议室内环境质量的优劣直接影响开会人员的工作效率。为分析布风器形式对会议室室内气流环境的影响。以某船舶会议室作为研究对象,以计算流体力学方法和传热学为基础,应用AIRPAK商用软件对会议室采用方形平板、圆形平板等4种布风器送风时的室内气流分布进行模拟。通过温度场、速度场、通风效率等的比较分析说明,孔板形布风器送风的温度场、速度场分布较均匀,热舒适性较好,平板形布风器送风的能量利用率高且除污效果较好。
The environment quality of conference rooms will directly affect the persons work efficiency.In order to analyze the effect of several air distributor forms on indoor air environment conference rooms,conference room of a ship as the research object,based on the computational fluid dynamics and numerical heat transfer theory,numerical simulation was taken for four different air distributor forms with the software AIRPAK,which are square plate、circular plate、square orifice and circular orifice.Through the comparative analysis of temperature field、velocity field and ventilation efficiency,etc,we have come to airflow temperature field and velocity field distribution of orifice-shaped air distributor are more even,and better thermal comfort;energy efficiency and decontamination effect of tablet-shaped air distributor are better.
