摘要
本文主要探讨的是约占我国能源总能耗3.78%~4.41%的北方城镇墙体热损失,以及如何减少材料使用量并增大墙体热阻。笔者对目前市场上应用的墙体保温材料做了优缺点分析,并根据现今市场价格低且可大规模应用的材料,提出了3个理论上可行的方案。通过比较得出:外墙外保温与墙体自保温结合使用及外墙内保温与墙体自保温结合使用相对于普通方案可提高热阻,减少使用材料,更有经济性。
This paper mainly discusses the heat loss of walls in northern cities and towns, which accounts for 3.78%~4.41% of the total energy consumption in China,and how to reduce the use of materials and improve the thermal resistance of walls. In this paper,the advantages and disadvantages of wall thermal insulation materials used in the market are analyzed,and three feasible schemes are put forward for wall thermal insulation materials which are cheap and widely used in the market.Through comparison, it can be seen that the combination of external thermal insulation and wall self-insulation,and the combination of external thermal insulation and wall selfinsulation can improve thermal resistance and reduce the use of materials,which is more economical than the general scheme.
