【摘要】 对于夏热冬暖地区,其气候特征主要是炎热潮湿,所以建筑隔热是夏热冬暖地区建筑节能的关键。本文通过理论计算,以广州地区为例,分析了隔热层在围护结构内的不同位置时对室内热稳定性的影响,得出用同样的隔热材料采用外隔热比内隔热好,且更有利于提高房间的热稳定性的结论。通过墙体的反应系数(BER)作计算比较得出加隔热层可以提高围护结构的热稳定性,同时有利于降低围护结构因传热引起的空调负荷,且外隔热的效果较内隔热更好。更多还原

【Abstract】 In hot summer and warm winter zone, its weather characteristic is primarily sultry and damp, so heat insulation is the key to energy efficiency.This text calculate through theory, take area of Guangzhou as an example, heat insulate layers effect on hot stability in the room while exterior- protected construction different positions.Draw that adopting outside heat insulation better than inside heat insulation with the same thermal insulator, and furthermore help to improve the conclusion of the room hot stability. Through calculate response coefficient ( BER) of wall can protect and improve hot stability of exterior- protected structure, to reduce air- conditioning load conducting from exterior- protected construction at the same time, and the result is that outside heat insulation is better than inside heat insulation.更多还原
