摘　　要：墙体外保温材料厚度对外墙采暖与空调能耗有很大的影响,其最佳厚度的确定对于外墙经济节能具有重要意义。选取3种典型的外保温材料——石墨改性膨胀聚苯板、改性聚氨基甲酸酯、普通EPS,通过软件模拟和计算分析,分别考察其用于北方严寒地区和寒冷地区的节能性能和经济性能。模拟结果显示:(1)不同气候区下,同种保温材料保温性能的发挥效果存在差异,保温材料在寒冷地区的节能量不及在严寒地区;(2)同种气候下、不同保温材料中改性聚氨酯的节能效果最好;(3)保温材料的厚度将影响墙体节能效果,石墨改性膨胀聚苯板材料、改性聚氨酯材料以及普通ESP材料等3种保温材料在寒冷地区用于建造的最佳厚度值分别为40 mm、26 mm、65 mm,在严寒地区的最佳厚度值分别为62 mm、44 mm、76 mm。希望能为建筑节能设计提供参考。The thickness of external thermal insulation material has a great influence on the energy consumption of heating and air conditioning of external wall, and the determination of the optimal thickness is of great significance for the economic and energy saving of external wall. Three kinds of typical external thermal insulation materials, including graphite modified expanded polystyrene board, modified polyurethane and ordinary EPS were selected. Through software simulation and calculation analysis, the energy-saving performance and economic performance of three typical external thermal insulation materials used in northern cold regions and cold regions of China were investigated respectively. The simulation results show that:(1) under different climate zones, the energy saving effect of the same kind of thermal insulation material is different, and the energy saving effect of thermal insulation material in cold area is not as good as that in severe cold area;(2) in the same climate, among different thermal insulation materials, modified polyurethane has the best energy-saving effect;(3) the thickness of thermal insulation material will affect the energy-saving effect of the wall. The optimal thickness of graphite modified expanded polystyrene board material, modified polyurethane material and ordinary ESP material for construction in cold area is 40 mm, 26 mm and 65 mm, and 62 mm, 44 mm and 76 mm in severe cold area. It is hoped that this study can provide reference for building energy saving design.
