摘要:
严寒地区分布范围广、气候条件复杂,现行标准规范以基准温度18℃的采暖度日数(HDD18)作为分区指标,将严寒地区划分为3个二级气候区。为分析该指标的适用性,通过EnergyPlus软件模拟并地较典型建筑在严寒地区61个城市的年累计热负荷差异,对比部分城市之间的气候特征,分析城市的HDD18与建筑年累计热负荷的关系,探讨HDD18分区指标的适用地区。结果表明:在HDD18相近的条件下,西部高海拔地区城市的建筑年累计热负荷显著低于东部城市;HDD18与建筑年累计热负荷仅在太阳辐射量及夏季温度差异较小的地区呈线性关系;HDD18作为分区指标,适用于太阳辐射及夏季温度差异小的地区,严寒地区宜结合太阳辐射等因素划分二级分区。

Abstract:
The severe cold climate zone in China has a wide distribution range with complex climate conditions, which was divided into 3 subzones according to heating degree days based on 18℃ (HDD18). In order to investigate the rationality of the current second level index for dividing climate region for building thermal design, the annual cumulative heating loads of typical buildings in 61 cities in severe cold climate zone were simulated by EnergyPlus software. The climatic characteristics of several cities were compared and the relationship between HDD18 and annual cumulative building heating load were explored. The results show that the annual cumulative building heating load in low-altitude region is much higher than that in high-altitude region with similar HDD18. The annual cumulative building heating load is linearly correlated with HDD18 only in the regions with small differences in solar radiation intensity and summer temperature. Therefore, HDD18 is suitable for zoning in areas with small differences in solar radiation and summer temperature, which should be combined with the solar radiation to divide climate region in severe cold climate zone.
Key words:  dividing climate region for building thermal design  severe cold climate zone  building load  solar radiation  degree days
