摘要
采用墙体模型的建立、热湿耦合数值计算、对比分析总结的研究方法,着重从墙体组构顺序方面,系统深入地研究了寒冷地区建筑墙体构造界面结露特性的影响机制。为优选出符合地域特点、满足节能要求、防结露效果最好的外墙防结露构造体系提供参考依据。并对极具发展前景的几种预制混凝土夹芯保温墙体进行结露计算和可行性分析,为装配式建筑外墙选择提供一定程度上的参考。
The establishment of the wall model the numerical calculation of heat and moisture coupling and the comparison and analysis of the research methods was used focusing on the sequence from the wall structure the system in-depth study of the cold wall building structure interface dew characteristics of the mechanism. Providing guidance for optimizing the best exterior wall that meet geographical features and meet the requirements of energy-saving effective anti-condensation of the best exterior wall anti-condensation system. The characteristics calculation of dew condensation and feasibility analysis of several precast concrete sandwich-thermal insulation walls with great development prospects are worked which to some extent provide effective guidance for the selection of exterior wall of assembled buildings.
