北方村镇住宅外围护结构的节能设计

A energy saving design method for outer walls of norther rural dwellings

本文根据热工理论分析及科研实验提出，靠火炕采暖的村镇住宅外墙的节能设计，必须以延迟时间ζI＞0.6ｈ为设计参数，墙体构造应放弃传统单一材料外墙，采用内保温复合墙体。实践表明，按本文提供的方法，能使住宅有效节能，外墙内表面结露、结冰霜问题得以解决，居住环境大为改善。

Based on thermodynamic analysis and experiment results, a energy saving design method for outer walls of northern rural dwellings is suggested in this paper. As the main design parameter, delay time mustn't be less than 0.6h. Single traditional material for outer walls must be given up. Composite wall structure with thermal isola- tion material inside should be adopted. It is proved in practice, dwellings designed accord- ing to the method can save energy effectively, inner sur- face of outer walls can be prevented from dewing and frosting, and the residential circumstance can be im- proved substantially.Some schemes for outer wall design are given also in the paper.
