摘　　要：在分析地板辐射供冷系统地面温度传热规律的基础上,建立了地板辐射供冷系统的二维稳态传热数学模型;进而利用有限单元法数值计算了地板供冷系统的地面温度,根据地面温度随供回水平均温度和室内温度的变化规律,给出了地板供冷系统适宜的供回水平均温度,最后提出了地板辐射供冷系统防止地板结露的措施,这对于地板辐射供冷系统优化系统设计,推广应用提供参考依据。On the basis of analyzing the heat transferring rule of the floor radiant cooling system,the mathematic model of two-dimensional steady heat transferring is set up.Moreover,by using FEM,the ground temperature is worked out.According to the law of the ground temperature changes with the mean temperature of the supplied water and returned and indoor temperature,the mean temperature of the supplied and returned water is obtained.Finally,specific measures are suggested on condensation-prevention,which can be used as reference for the optimizing design and application of the floor radiant cooling system.
