摘　　要：以沈阳地区某房间(采用地板辐射供暖系统)作为研究对象,建立房间物理模型、传热模型及PMV(预期平均评价)、PPD(预期不满意百分率)数学模型。将人体中间截面作为分析面,在地板表面温度为24、26、28℃条件下,采用CFD模拟软件对分析面的温度场、PMV值、PPD值分布进行模拟。设定条件下,最佳地板表面温度为26℃,人员高度范围内温度适中,PMV值理想,PPD值较低。Taking a room using fluor radiant heating system in Shenyang region as the research ob- ject,the physical model of the room, the heat transfer model and Predicted Mean Vote （PMV）, Predicted Percentage of Dissatisfied （PPD） mathematical models are built. The midsection of the human body is taken as the analytical surfahce, and the temperature field, PMV value and PPD value of the analytical surface are simulated by CFD simulation software at the floor sur face temperatures of 24 ℃ ,26 ℃ and 28℃. Ureter the given conditions, the optimal floor surface tempera- ture is 26 ℃, the temperature in the personnel height range is moderate, the PMV value is ideal, and the PPD value is lower.
