置换通风气流组织的特性研究

Characteristic research of air distribution of displacement ventilation

采用数值模拟方法,对应用置换通风方式的办公房间气流组织的速度场、温度场进行计算并作图形化处理,分析置换通风气流组织的特性,通过改变围护结构的传热系数,简要分析其对气流组织的影响,并提供评价这种通风方式舒适性的参考数据。

Adopts numerical simulation, calculates the air distribution of an office which apply displacement ventilation, uses figure show its velocity field and temperature field,analyzes its characters, through the change of heat transfer coeffcient, briefly analyzes its infection, offers reference to evaluate the comfort characteristic of this kind of ventilation system.
