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.
