【摘要】：本文以有集中热源的办公室建筑为例,在相同送风量和相同送风温度条件下,研究比较了两种直接向呼吸区送风(竖壁贴附射流加导流板送风和层式送风)的气流组织特性,分析比较了两种送风方式的温度场和速度场及温度和速度随房间高度的变化.研究结果表明,两种送风方式下,新风都可以直接达到呼吸区内,呼吸区内空气品质良好,但竖壁贴附射流加导流板形成的竖壁贴附呼吸区送风可以在工作区内形成一个速度和温度都更加均匀的空气湖环境,且能够获得较好的舒适度.该研究为竖壁贴附呼吸区送风的新型气流组织设计提供了参考依据.
[Abstract]:Taking an office building with concentrated heat source as an example, under the same air supply rate and the same air supply temperature, this paper studies and compares the airflow structure characteristics of two kinds of direct air supply to the respiratory area (vertical wall attached jet plus guide plate supply air and layer type air supply). The temperature field and velocity field and the variation of temperature and velocity with room height were analyzed and compared. The results show that the fresh air can reach the respiratory zone directly and the air quality in the breathing area is good. But the vertical wall attached to the jet and the baffle formed by the vertical wall attached to the breathing area can form a more uniform air lake environment with more uniform velocity and temperature in the working area, and better comfort can be obtained. This study provides a reference for the design of new airflow organization in the vertical wall attached to the breathing area.
