摘　　要：基于1971年至2003年的大量实测气象数据,通过对夏热冬冷地区20个典型城市的气候条件分析,揭示了各城市在最冷(热)月平均温度及日较差、日均温度≤5℃(≥25℃)的天数和采暖、空调度日数等方面存在巨大差异.探讨现有标准规定的3套计算期的合理性,基于实测气象数据和离散性分析,提出新的计算期确定方法.采用Design Builder软件对居住建筑的能耗模拟结果表明,不同计算期不仅影响采暖、空调能耗的总量,而且改变了两者之间的比例关系.Large amounts of actual measured meteorological data of 20 typical cities in hot summer and cold winter zone in China between 1971 and 2003 were analyzed.There exist wide differences in climatic conditions among cities in this climate region,as reflected in many aspects like the average temperature and diurnal range in coldest（hottest）month,the number of days in which the daily average temperature was less than or equal to 5 ℃（higher than or equal to 25 ℃）,the heating and cooling degree day,etc.The reasonability of calculation periods set by three existing relevant standards in China was investigated,and a new defining method of calculation period was proposed based on actual measured meteorological data and discreteness analysis.The results of energy consumption simulation for residential buildings with the Design Builder software indicate that different calculation periods not only affect the total heating and cooling consumption simulation result,but also change the ratio of them.
