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:
The paper takes an office of concentrated heat source as an example. Under the same condition of supply air rate and temperature, the research compares characteristics of air distribution formed by two kinds of supply air directly to the breathing zone (air curtain ventilation with deflector and stratum ventilation), analyzes the two kinds of the temperature field and velocity field, variation of temperature and speed with the change of room height are also studied. The results show that fresh air can both directly reach the breathing zone in two air supply modes, where high air quality forms. But air curtain ventilation with deflector can form an air lake in which air velocity and temperature are uniform, so we may feel more comfortable.
