摘要
严寒地区在未来气候变暖条件下节能建筑的设计方法对于我国建筑节能技术发展具有重要意义.以稳态传热理论为基础,提出了严寒地区节能建筑围护结构传热系数限值与气温升高的关系模型.使用该模型分析:随着气候变暖采暖能耗降低,严寒地区围护结构传热系数的要求可降低.以哈尔滨为例,结合气候模拟与动态能耗模拟技术,验证了2021-2050期间严寒地区节能建筑传热系数变化规律.依据等能耗原则,研究了外墙与窗户传热系数趋同的自保温构造体系在变暖的严寒地区的适用性.
The design method of building energy efficiency in severe cold zone in future warming climate conditions has great significance for the development of building energy efficiency technology in China. The formula that the heat transfer coefficient change with temperature rise was given. The effects of changes in heat transfer coefficient on building energy consumption in severe cold zone after climate warming was analyzed in Harbin combining climate simulation with dynamic energy simulation techniques. Studies have shown that as the climate warms, the heat transfer coefficient can reduce in severe cold zone between 2021-2050. Based on the principle of equal energy consumption that the heat transfer coefficient of exterior walls and windows in self- thermal insulation system is equal its suitability was demonstrated.
