| 摘 要： | 选取重庆某住宅卧室进行实测分析,在供水温度为20、18、16℃,室外天气为晴天、多云、阴天(雨)工况下,研究毛细管地板供冷房间温度、地板供冷量、地板结露特征。供水温度为20、18、16℃时,室内最高温度27.6℃,最大供冷量分别为23、33、32 W/m2。开始结露时间为10:30—14:50之间,其中80%区域开始结露的时段为11:00—13:00之间,室内气流涡旋区最早出现结露。供水温度为18℃时,除湿能明显改变地板结露现象;供水温度为16℃时,除湿能改变大部分地板结露现象,室内气流涡旋区仍为结露区,但结露时间延后1h以上。地板结露区域与室内气流组织有关,毛细管铺设位置应避开房间气流漩涡区。

| Abstract: | Indoor temperature,cooling capacity and condensation characteristic of capillary tubes for floor cooling were specially investigated with 20 ℃,18 ℃,16 ℃inlet water temperature.Experiment was carried out in a bedroom in Chongqing in sunny,cloudy and overcast weather condition.The results showed that the highest indoor temperature was 27.6 ℃,the maximum cooling capacity were 23 W/m2 ,33 W/m2 ,32 W/m2 respectively.Adverse condition of condensation was happened between 10:30 to 14:50,among which 80%area started condense from 11:00 to 13:00.Indoor air eddy area was very easy to be condensed. The dehumidifier could reduce condensation dramatically with 18 ℃ inlet water,but eddy area was still condensed with 16 ℃inlet water,The condensation area was related to indoor air distribution,the capillary tubes should be installed avoid air eddy area. |
