摘　　要：利用计算流体动力学方法,通过PHOENICS分别对辐射地板与置换通风(DV),层式通风(SV)和混合通风(MV)相结合的复合系统进行模拟分析。得出不同地板温度,送风方式以及送风参数的室内速度和温度分布。结果表明在不考虑室内污染物的情况下,通过改变送风温度,速度以及地板温度时,置换通风中由垂直温差引起的竖直不满意率略高于其他通风方式。地辐射与不同通风方式相结合的复合系统均可以达到较好的热舒适。Using the computational fluid dynamics method, the composite system of radiant floor and displacement ventilation(DV), stratum ventilation(SV) and mixed ventilation(MV) was simulated and analyzed by PHOENICS,respectively. The indoor velocity and temperature distributions under different floor temperature, ventilation method and supply air parameters are obtained. Results show that in the absence of indoor pollutants, the vertical dissatisfaction rate caused by vertical air temperature differences in DV system is slightly higher than that of other ventilation methods.Radiant floor cooling combined with different ventilation systems can achieve a good performance of thermal comfort.
