摘要
为说明地板辐射采暖在大空间候车站的应用可行性,简要介绍了地板辐射采暖的原理及特点,采用CFD技术对低温地板辐射采暖的铁路车站候车厅温度场和速度场进行数值模拟研究,通过分析室内空气温度梯度、地板表面温度、候车区的热舒适性(PMV)及不满意率(PPD),对候车厅等高大空间采用低温地板辐射采暖的设计方案进行验证,计算结果表明PMV-PPD满足国际标准ISO7730推荐值,说明地板辐射采暖在大空间建筑应用是一种较舒适的采暖方式。
In order to testify the feasibility of the radiant floor heating applied in the station hall with large space, the theory and characteristic of radiant floor is introduced and the CFD technique is employed to simulate the temperature and velocity distribution in a station hall with large space. The temperature gradient of indoor air, floor surface temperature, PMV and PPD are used to evaluate the effect of the design scheme. The simulation results show that the PMV-PPD can meet the recommended value of the international standard, ISO7730 and the radiant floor heating is suitable for the large space.
