夏热冬冷地区住宅供暖气候分区研究

STUDY ON THE CLIMATE DIVISION OF RESIDENTIAL HEATING IN HOT SUMMER AND COLD WINTER REGIONS

针对夏热冬冷地区分布范围广、气候差异大的特点及冬季供暖问题,从冬季室内热环境和居民需求等方面分析了供暖分区的必要性;并基于64个代表城市的典型气象年数据,对该地区内部气候特征差异性进行分析,确定累年最冷月平均温度、采暖度日数(HDD18)和1月份太阳总辐射为分区指标,采用系统聚类分析的方法,将夏热冬冷地区划分为北部高供暖Ⅰ区、中部供暖过渡Ⅱ区、南部低供暖Ⅲ区,并分别针对各供暖分区提出各区适宜的供暖模式。

In the light of the hot summer and cold winter zone wide distribution,large difference of climate characteristics and winter heating problems,from the indoor thermal environment in winter and residents＇ demand the necessity of heating partitions were analyzed. Based on the 64 representatives of the city＇s typical meteorological year data,by analyzing the internal climate characteristic of the region, the determined coldest month average temperature,heating degree days（ HDD18） and January total solar radiation were used as zoning index,and then the method of cluster analysis was used to divide hot summer and cold winter regions into the northern region of high heating zoneⅠ,central heating transition zone II,the southern low heating zone III,and finally the suitable heating mode was proposed respectively for each partition,which could provide a reference for the design of the winter heating in hot summer and cold winter regions.
