调湿型涂料对建筑室内热湿环境影响的实验研究

Experimental Study on the Effects of Humidity-Adjusting Paint on Indoor Thermal Environment of Buildings

为研究调湿型涂料对建筑室内空气温度和相对湿度的调节性能,对涂装了调湿型涂料的房间(实验房)内的空气温湿度进行全天候的动态测量,并与未涂装调湿型涂料的房间(对比房)进行对比.研究发现:当室外环境温度与相对湿度的日变化区间分别为26~33℃和35%~85%时,开启门窗条件下实验房内空气温湿度变化范围分别为28.3~30.2℃和49.3%~63.5%、关闭门窗条件下实验房内空气温湿度变化范围分别为28.9~29.6℃和57%~61%.与对比房比较,实验房内的空气温湿度变化范围更窄.此外,实验房内的温湿度变化与对比房内和室外空气的温湿度保持相似的趋势,但是变化幅度更平缓.研究表明:调湿型涂料可以比较有效地调节建筑室内的空气温度和相对湿度、改善室内热湿环境,是一种节能环保的被动式建筑环境控制材料.

In order to study the effects of the humidity-adjusting paint on the indoor air temperature and relative humidity,the dynamic measurements were conducted in a room with its inside coated by humidity-adjusting paint （ Test room） and another room without the paint （ Control room） .The experiment was carried out when the outdoor air temperature and relative humidity ranged from 26 -33℃ and 3 5 % -8 5 %, respectively. The results showed that the air temperature and relative humidity in the test room ranged from 28.3 - 30.2℃ and 49.3% -6 3 . 5 %, respectively,when the doors and windows were opened.And the air temperature and relative humidity in the control room ranged from 28.9 -29.6℃ and 57%-61%, respectively,when the doors and windows were closed.And the narrowed ranges of air temperature and humidity were observed. Furthermore, the air temperature and relative humidity variations in the test room were found to be similar with the changes of the outdoor air and that of the control room, and more gentle changes in the indoor air tem-perature and relative humidity were also observed.The results indicated that the humidity-adjusting paint could adjust the indoor air temperature and relative humidity, and improve the indoor thermal environment effectively.
