摘要:
在18℃供水温度下,对重庆地区毛细管网辐射供冷系统进行实验测试,分析了毛细管网顶棚、墙面、地面3种敷设方式的室内热工参数。结果表明:毛细管网顶棚、墙面、地面3种敷设方式供冷稳定时,人员活动区的平均温度依次为26.27、27.22、26.57℃,辐射表面平均温度依次为20.96、21.14、22.76℃,PMV依次为-0.27、0.32、-0.2,PPD依次为7.06%、7.47%、6.34%。在实验条件下,3种敷设方式供冷时室内温度均能满足≤ 28℃的要求,PMV、PPD均能满足《民用建筑室内热湿环境评价标准》(GB/T50785-2012)Ⅰ级热舒适评价指标。

Abstract:
Tests of capillary radiant cooling system in Chongqing were carried out and thermal parameter were analyzed in conditions of three different capillary laying modes (ceiling, wall and floor) with 18℃ supply water temperature. It concluded that when capillaries were laid on the ceiling, wall and floor respectively, the average temperature of working area was 26.27, 27.22 and 26.57℃ respectively and the radiation surface temperature was 20.96, 21.14 and 22.76℃ in turn. By calculation, the PMV of three conditions was -0.27, 0.32 and -0.2 PPD results were 7.06%, 7.47% and 6.34% respectively. It illustrated that all three laying ways at this experimental conditions could meet the air temperature requirements (no more than 28℃) and PMV, PPD attain thermal environment category I.
Key words:  capillary  radiant cooling  laying way  indoor environment
