摘要:选取我国2部典型年气象数据集,利用聚类算法分析了全国区域内供冷年耗冷量的分布情况,探讨了典型年气象数据更新条件对不同地区供冷年耗冷量的影响。针对《近零能耗建筑技术标准》中供冷年耗冷量未给出具体指标限值及控制性参数WDH20和DDH28在工程设计中不易获取、计算不便等情况,参照该标准中相关能效指标的限定,结合建筑热工设计分区,对供冷年耗冷量进行了分析比对,进一步给出了建筑热工设计二级区划下供冷年耗冷量的指标参考范围。

Abstract: This paper selects two typical year meteorological data sets in China, uses the clustering algorithm to analyse the distribution of annual cooling consumption in the national region, and explores the influence of the updated conditions of typical annual meteorological data on the annual cooling consumption of different regions. In view of the fact that the specific index limits of the annual cooling consumption are not given in the Technical standard for nearly zero energy buildings and the control parameter WDH20 and DDH28 are not easy to obtain and inconvenient to calculate in engineering design, with reference to the limitation of the relevant energy efficiency indexes in the standard, combined with the building thermal design zoning, the annual cooling consumption is analysed and compared. The index reference range of annual cooling consumption under the secondary zoning of building thermal design is given.
Keywords: nearly zero energy building; annual cooling consumption; building energy efficiency; energy efficiency index; meteorological data update;
