基于个性化送风的“凸”字形送风口气流组织研究

Simulation and experimental research of air distribution for a new convex-shaped outlet based on personalized ventilation

为提高特定工作区域的气流组织效果,研发了一种基于个性化送风的"凸"字形送风口。该送风模式的特点为:根据不同操作者的体型,通过改变风口位置、送风速度,实现低速送风,保障人体处于较为舒适的环境。详细介绍了实验系统和数值模拟方法,并对结果进行了深入分析。结果表明,该送风方式可以实现按需送风,较好地解决了不同人员舒适性要求存在的差异性问题。

In order to improve the air distribution effect of certain working area, develops a new air outlet based on personalized ventilation. The characteristic of this mode is providing air at low velocity to ensure occupancy always in the comfortable environment by changing air outlet position and air velocity. Elaborates the experiment system and mathematical simulation method, and analyses the results in detail. As a result, the air supply mode can supply air on demand and solve the problem of occupants＇ different thermal comfort requirements.
