摘要:
建筑材料含湿对其导热系数的影响较大，且该影响在热湿气候区尤为明显。目前，在建筑节能工程计算中，仍无法准确计算含湿建筑材料的导热系数，对其依然采用规范给出的参考值，这必然造成围护结构热工性能及建筑节能计算的不准确性。本文以含湿建筑材料导热系数为研究对象，对业界在模型预测、实验测试等方面取得的进展进行了深入的研究分析，总结了国内外在含湿材料导热系数研究中所取得的主要成果。针对存在的问题，指出了其应用的局限性，同时展望了该领域的发展趋势。
Abstract:
The moisture content of building materials has great influence on the thermal conductivity, especially in the hot humid climate zone. At present, in the calculation of building energy saving, we are unable to accurately calculate the thermal conductivity of moist building materials, which is still adopted the reference value. That will inevitably lead to the uncertainty of thermal performance of building envelope and the inaccuracy of calculation of building energy-saving. In this paper, taking the thermal conductivity of moist building materials as the research object, the progress of the model prediction and experimental testing were deeply studied and analyzed. In addition, the main achievements at home and abroad about studying the thermal conductivity of moist building material were also summarized. In view of the existing problems, the limitations of its application were pointed out, and the development trend of this field was prospected
