摘　　要：通过对辐射吊顶+地板送风系统夏季运行情况的试验研究,得出了室内温湿度沿高度方向的变化情况以及贴附层露点温度的分布情况。结果表明,室内空气温度沿高度方向先升高后降低,而相对湿度则先下降后上升,送风参数对房间湿度的影响较大,辐射板表面温度可根据贴附层的露点温度进行控制,而贴附层的露点温度可以采用工作区露点温度减去1.7℃来表示。By experimental study of radiant air-conditioning and underfloor air distribution system in summer, it is concluded that the indoor air vertical distribution of temperature and humidity and the distribution of the the attached layer dew point temperature. The results show that, indoor air temperature increases at first then reduces, and the relative humidity increases after the reducing, supply air parameters have a big effect on the room moisture, we can calculate the indoor temperature dew point minus 1.7℃ instead of the dew point temperature of the attached layer to control the radiant plant temperature.

关 键 词：温湿度分布 贴服层 露点温度
