摘要

由于进入通风腔的热通量较低，高度隔热的预制木质屋顶结构的湿热性能可能会下降。本文评估了在北欧气候条件下，通过采用不同的屋顶通风率控制方法和在屋顶覆面板上方使用隔热材料来提高此类屋顶防潮安全性的可能性。研究结果支持使用自适应屋顶通风，因为它可以降低屋顶霉菌生长的概率。在屋顶覆面板上使用隔热材料只能略微降低内置湿度较高的屋顶中霉菌生长的几率。

A Numerical Study of Methods to Improve Moisture Safety of Ventilated Wooden Roofs

The hygrothermal performance of highly insulated, prefabricated wooden roof structures is likely to deteriorate due to the low heat flux to the ventilation cavity. This article evaluates the possibility to improve the moisture safety of such roofs in a Nordic climate by using different control methods for the ventilation rate of the roof and by using thermal insulation above the roof sheathing. The results support the use of adaptive roof ventilation as it decreases the probability of mould growth in the roof. The use of thermal insulation above roof sheathing decreases the probability of mould growth only slightly in a roof with elevated amount of built-in moisture.
