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。
The outdoor atmospheric temperature passes through the thermal wall into the room, greatly reducing the fluctuation and crest delay, which is of great significance in saving energy and reducing consumption. In this paper, a one-dimensional unsteady heat transfer model of thermal wall was established. The heat transfer performance of the thermal wall used in a zero-energy building was simulated. The simulation results were compared with the actual measured wall temperature and Heat flow rate kiss and good. Then, the model was further used to analyze the adaptability of thermal wall on behalf of cities in five typical climatic regions in China. The results show that thick enveloping structure is suitable for large temperature difference between day and night and large average temperature difference between indoor and outdoor, The phenomenon in summer and cool area is relatively insignificant.
