热质墙体在我国的热适应性研究

室外大气综合温度通过热质墙体传入室内,波动大大衰减,波峰延迟,在节能降耗中具有重要意义。本文首先建立了热质墙体的一维非稳态传热模型,对应用在一栋零能耗建筑中的热质墙体传热性能进行了模拟,模拟结果与实际检测的墙体温度和热流率吻和良好。而后进一步利用该模型分析了热质墙体在我国5类典型气候区域代表城市的适应性,结果表明在昼夜温差大、室内外平均温差大的地区较适宜采用厚重围护结构,而在冬暖夏凉地区现象相对不明显。

Research on Thermal Adaptability of Thermal Mass Wall in China

Through thermal mass wall,the time-dependent fluctuation of the outside integrated air temperature can be delayed and weakened,which is of great importance for building energy conservation and consumption reduction.In this paper,one-dimension unsteady-state heat transfer model for thermal mass wall was firstly established,and the heat transfer property of thermal mass wall of a zero-energy consumption building was simulated,the calculation results of wall surface temperature and heat flux were in accordance...
