高湿或低湿环境不仅与许多健康问题密切相关，而且对建筑的耐久性和能耗也有很大影响。为了获得健康舒适的室内环境，控制湿度是非常重要的。然而，居住住宅的各种空气湿度问题在中国身上还没有得到认真的考虑。此外，几乎没有关于中国住宅实际湿度环境的信息。为此，很难选择合适的适度湿度策略来维持和谐的室内湿度水平。目前，作者对中国9个城市的室内热环境进行了现场测量。在此基础上，本研究旨在建立室内湿度适中设计的数据库，以识别和澄清中国住宅室内湿度环境的特征。结果表明，一些城市冬季安装集中供暖系统的住宅，室内湿度水平过低，相对湿度低于20%。另一方面，冬季一些住宅供暖不足、室外湿度较大的城市，室内湿度很高，相对湿度超过80%。严峻的室内湿度环境表明，中国居民楼的湿度水平必须得到缓解和控制，才能实现可持续健康的室内环境。(C)2010爱思唯尔有限公司。保留所有权利。
A high or low humidity environment is related closely to not only many health problems, but also has great influence on the construction durability and energy consumption. It is very important to control humidity level, in order to achieve a healthy and comfortable indoor environment. However, various problems of the air humidity in inhabited dwellings are not yet taken serious consideration in China. Moreover, there is hardly any information available regarding the actual humidity environment in Chinese residential houses. For this reason, it is difficult to select appropriate moderate moisture strategies to maintain a harmonious indoor humidity level.The current authors carried out a field measurement survey on indoor thermal environment in nine Chinese cities. Based on this investigation, the purpose of this present study is to develop a database of actual indoor humidity conditions for moisture moderate design, through which the characteristics of indoor humidity environment in Chinese residential houses can be identified and clarified.The results demonstrated that the indoor humidity level is too low with the relative humidity falls below 20% in some cities where residences equipped with central heating system in winter. On the other hand, indoor humidity is very high with the relative humidity beyond 80% in some cities where residences have inadequate heating and high outside humidity ratio in winter. The severe indoor humidity environment indicated that the moisture level in the residential houses of China should be mitigated and controlled in order to achieve a sustainable and healthy indoor environment.
