%X 对重庆地区毛细管网辐射供暖系统进行测试，分析在35℃供水工况下毛细管网顶棚、墙面、地面3种敷设方式的室内空气温度、围护结构壁面温度等参数。结果表明：在重庆地区35℃供水工况下，毛细管网顶棚、墙面、地面3种敷设方式供暖稳定时，室内人员活动区平均温度分别为16.53、16.4、16.94℃、辐射表面平均温度分别为29.21、28.17、22.98℃，纵向最大温差分别为1.76、3.16、0.3℃，水平最大温差分别为-0.26、0.59、-0.34℃，在实验条件下，该地区3种敷设方式供暖时室内温度均 ≥ 16℃，毛细管网构造层厚度与敷设位置直接影响室内舒适度。<br>Tests of capillary radiant heating system in Chongqing district were carried out and indoor temperature, surface temperature of envelope in condition of three different capillary laying modes (ceiling, wall and floor) with 35℃ supply water temperature were analyzed. The experimental data indicates that in the three different conditions, when the temperature of the supply water is 35℃, the average temperature of indoor air is 16.53℃, 16.40℃ and 16.94℃ respectively and that of radiation surface is 29.21℃, 28.17℃ and 22.98℃ respectively. The largest vertical temperature difference tested is 1.76℃, 3.16℃ and 0.3℃ while the largest horizontal difference tested in the direction fall is -0.26℃, 0.59℃, -0.34℃ respectively. It is shown that the system meets the requirements of indoor temperature 16℃ in three conditions. Both the thickness of capillary structure layer and the laying mode have an directly influence on the indoor thermal comfort.
