架空通风地板传热系数研究

Study of heat transfer coefficient of ventilated raised floor

采用稳态传热方法和等量传热原则得出了以架空层通风量为主要影响参数的地板传热系数计算公式,应用CFD软件模拟了通风口面积比与通风量的关系,给出了常用通风口设置情况下地板传热系数建议值。

Based on steady heat transfer method and equivalent heat transfer principle,proposes a formula of heat transfer coefficient of ventilated raised floor,in which ventilation quantity under the floor is the main influencing factor.Simulates the relation between area ratio of ventilation opening and ventilation quantity with software CFD.Provides the recommended heat transfer coefficient value for commonly encountered ventilation opening conditions.
