摘要
青藏高原地区冬季寒冷且极端干燥,建筑冬季室内增温、加湿需求已同等迫切。本文在西藏拉萨市冬季条件下,对建筑室内湿源扩散特性进行大量实验测试分析,初步得到了加湿量、湿组分相态、湿组分温度和湿源位置等因素影响下室内湿度场的基本分布规律,为高原特殊气候条件下室内湿环境营造奠定了基础。
The Qinghai-Tibet Plateau is cold and extremely dry in winter,which makes the demand for indoor heating and humidification in winter is equally urgent.This paper conducted an experimental study on the diffusion of indoor moisture sources in Lhasa,Tibet,in winter,and initially identified the basic distribution law of the indoor humidity field under the influence of multiple factors,such as the humidification amount,the phase state and temperature of the wet component and the location of the source,providing a foundation for the construction of an indoor humidity environment under extreme climatic conditions on the plateau.
