摘要
利用 NORDTEST 实验方法对中国长江中下游地区（以南京为例）多孔调湿材料的湿缓冲值（Moisture Buffer Value）进行测定，同时，研究湿缓冲值对建筑能耗及室内湿度的影响。实验结果显示，高湿度区间内材料的湿缓冲测定值较大，且不同材料的湿缓冲值存在较大差异。分析表明在长江中下游地区，使用具有吸放湿特性的建筑内表面材料可有效降低建筑能耗10％以上，同时，室内环境湿度也会得到一定程度的调节。
Abstract
A series of experimental tests using NORDTEST method for evaluating the moisture buffering capacity of different porous hygroscopic materials have been carried out in the Yangtse River downstream area (Nanjing for example),.The impact of MBV on building energy consumption and indoor humidity has also been investigated.The test results show that the MBV of porous hygroscopic materials is larger under higher humidity range,and there was obvious difference when using diverse materials.Research indicates that it may be possible to reduce up to 10% cooling energy consumption in the Yangtse River downstream area(hot and humid climate)in China,when applying hygroscopic materials with well-controlled HVAC systems.Meanwhile the indoor humidity can also be modulated to a certain extent.
