| 摘 要： | 现代轻质建筑热容较小,窗墙比较大,冬季在利用透射太阳辐射采暖的同时易造成室内温度波动过大。本文提出将定形相变蓄能板安装在建筑内隔墙表面,以增加建筑热容,减小室温波动。采用经实验验证程序,模拟分析了相变板热物性、表面换热系数和用量对冬季室内温度波动的影响,给出了北京地区相变内隔墙房间的设计原则。

| Abstract: | Lightweight envelopes are more and more frequently used in modern buildings,but they lack sufficient thermal inertia for solar energy utilization in winter.To increase the thermal capacity of the lightweight house,a kind of shape-stabilized phase change material(SSPCM) panel is employed on the surface of partition walls to lower the fluctuation of indoor temperature.The effects of the thermal properties,surface heat transfer coefficients and amount of the PCM panel on the indoor temperature are analyzed usi... |
