近零能耗居住建筑供冷年耗冷量指標分析研究
Analysis and study of annual cooling consumption indicator of nearly zero energy residential buildings
摘要：
選取我國2部典型年氣象數據集，利用聚類算法分析了全國區域內供冷年耗冷量的分布情況，探討了典型年氣象數據更新條件對不同地區供冷年耗冷量的影響。針對《近零能耗建筑技術標準》中供冷年耗冷量未給出具體指標限值及控制性參數WDH20和DDH28在工程設計中不易獲取、計算不便等情況，參照該標準中相關能效指標的限定，結合建筑熱工設計分區，對供冷年耗冷量進行了分析比對，進一步給出了建筑熱工設計二級區劃下供冷年耗冷量的指標參考范圍。
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.
