夏热冬冷地区外墙内保温热湿耦合特性研究

Heat and Moisture Coupling Characteristics of Exterior Wall in Hot Summer and Cold Winter Zone

墙体保温技术能够经济有效地实现建筑节能。其中,墙体内保温技术虽然因存在结露风险而受到质疑,但是对于建筑的改造而言,内保温技术是最经济实用的。要推广内保温技术的使用,就要准确认识内保温墙体的结露情况,而这与墙体内部热湿传递有关。使用软件Delphin研究了在夏热冬冷地区冬季工况下,离心玻璃棉内保温墙体的热湿传递特性。

The wall insulation technology is a very effective and economical way to realize building energy conservation.In the technologies of insulation,the internal insulation is questioned because of the risk of condensation.But for the reconstruction of existing building,the internal insulation technology is the most economical and convenient.To promote the use of internal insulation technology,we should have an accurate understanding of the condensation of the internal thermal insulation wall,and the condensation of the internal insulation wall is related to the heat and moisture transfer inside the wall.The paper uses the Delphin to simulate the heat and moisture transfer property of centrifugal glass wool insulation wall in winterin hot summer and cold winter area.
