摘　　要： 对U型毛细管房间建立三维流固耦合模型,运用fluent软件模拟了室内存在热源的情况下房间内的温度场及速度场,模拟结果表明在自然对流情况下,毛细管辐射供冷能满足室内人员的热舒适性。分析了不同工况下毛细管内水流速及送回水温度对毛细管制冷能力的影响,得出了毛细管的最佳运行参数。分析了抹灰层对毛细管制冷能力的影响,从而为实际工程中抹灰层材料、厚度的参数选择提供了一定的依据。 Model 3-dimentional room with U-tube capillary mats and simulate with fluent velocity distribution and temperature distribution of the room with heat resources which is cooled by U-tube capillary mats, the simulated results prove that under nature convection effects the tube capillary mats radiant system could reach thermal comfort of occupants . Analyze the influent factors of the cooling capability of tube capillary mats such as supply water velocity and temperature, and the best performance factors is presented. Analysis of tube capillary mats floated concrete effects on cooling capacity is important references of how to choose floated concrete material and material thickness in projects.
