【英文篇名】 Load decrease rate of the same building with the same energy saving measures under different climatic conditions 【作者中文名】 龙恩深; 付祥钊; 王亮; 崔天; 【作者英文名】 By Long Enshen★; Fu Xiangzhao; Wang Liang and Cui Tian Chongqing University; Chongqing; China; 【作者单位】 重庆大学; 【文献出处】 暖通空调, Hv 住宅建筑; 负荷减小率; 特征温度法; 空调; 供暖; 节能率; 【英文关键词】 climatic condition; residential building; load decrease rate; characteristic temperature method （CTM）; air conditioning; heating; energy saving rate; 【摘要】 以广州、重庆、北京等12个城市为对象,分别以DOE2中的TMY2,DeST-h中的TRY及修改的TMY2辐射数据,构建了36组完全不同的8760h气象数据库,利用特征温度法模拟计算相同建筑在围护结构改进前后单位建筑面积的全年空调和供暖耗能量。研究发现,对所涉及的城市,尽管因三种气象数据库(36组)显著不同,导致计算出的围护结构改进前后(72组)建筑全年空调供暖负荷、负荷减小量存在很大的差异,但是在不同气象条件下对模型建筑采取相同的节能措施,各城市全年空调负荷减小率(节能率)是相近的;各个城市全年供暖负荷减小率(节能率)也是相近的。从而证明了现行各国标准均规定围护结构K限值的通常做法是完全正确的。 【英文摘要】 Taking twelve cites including Guangzhou, Chongqing, Beijing as objects, builds up 36 groups of utterly different 8 760 h weather database on the basis of TMY2 in DOE2, TRY in DeST-h and modified radiation data of TMY2. Simulates annual cooling and heating energy consumption per building area of the same building before and after the improvement of building envelope by way of characteristic temperature method (CTM). Finds out that three kinds of different weather database, 36 groups, results in great differe...
