| Abstract: | 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 temperaturel6℃ in three conditions.Both the thickness of capillary structure layer and the laying mode have an directly influence on the indoor thermal comfort. |
