节能建筑复合墙体的非稳态热工性能

为节约土地资源和降低建筑主体结构工程造价，采用有限差分法、谐波法和反应系数法对节能建筑复合墙体的非稳态热工性能进行全面分析．复合墙体的传热反应系数、衰减倍数、延迟时间、热惰性指标和逐时壁温的计算结果表明，复合墙体对冬季供暖和夏季空调都具有良好的节能效果，其热稳定性和室内舒适性较传统非节能墙体有所提高；尽管外保温复合墙体的热惰性指标有所降低，但其夏季隔热性能却有所提高；外保温墙体的热工性能在冬夏两季均优于内保温墙体。

Unsteady Thermal Characteristics of Wall Insulation in Low Energy Consumption Building

In order to save soil resources and reduce building principal part structure engineering cost, finite difference method, harmonic wave method and response coefficient method have been utilized to analyze the unsteady thermal characteristics of wall insulation in low energy consumption building.The calculating result, including heat transfer-method of reaction coefficient, attenuation multiple, delay time, index of heat inertia, hour-to-hour wall temperature, shows that the composite insulator wall has favorable energy saving effect on winter heating and summer air conditioning, and can also improve the comfortability of indoor thermal environment.Although the index of heat inertia decreases, the thermal insulation capability of exterior insulator wall in no air-conditioning room in summer precedes that of the traditional wall.The unsteady heat transfer thermal characteristics of exterior insulator wall are better than that of interior insulator wall in winter and summer.
