摘　　要：对间歇用能模式下外保温及内保温墙体的热特性进行了实验研究,持续测量了实验环境舱围护结构各表面温度及室内外空气温度,进而计算得到了外保温、内保温房间的升(降)温反应系数和蓄热负荷,并比较了2种保温方式的节能效果。结果表明,外墙内保温房间空气升(降)温速度显著高于外保温房间,蓄热负荷低于外保温房间,节能效果明显。Experimentally studies the thermal characteristics of exterior-wall with internal or external thermal insulation under intermittent energy-using mode. Continually measures the outdoor, indoor air temperatures and the all wall surface temperatures,then calculates the air temperature rising （declining）reaction rate and heat storage loads of the rooms with internal or external thermal insulation,and compares the energy saving effects of this two thermal insulation methods.The results show that the internal insulation room has a higher heat reaction rate and lower heat storage load,and the energy saving effect is obvious.
