摘要
利用有限元仿真技术,对三类保温墙体稳态条件下的热力学行为进行研究,研究表明外墙外保温既能保护墙体,又有很好的热稳定性,同时建立模型描述保温层的厚度和导热系数对外墙外保温系统的保温性能的影响,进而从机理上研究其对复合墙体保温性能的影响,探索最佳的保温措施。
The paper studies the thermodynamics of three kinds of insulating walls under stable conditions by using finite element simulation technology. The research results show that： external wall insulating can not only protects the wall but also has great heat stability. Meanwhile, it describes the impact of thermal insulating layer thickness and thermal conductivity coefficient upon external wall insulating system by establishing models, discusses its impact upon compound wall insulating performance from the aspect of mechanism, and explores its optimal thermal insulating measures.
