摘要
本文对间歇用能模式下的自保温、外保温及内保温的热性能进行实验研究。研究结果表明,比起外墙自保温和外保温这两种保温方式,外墙内保温的房间空气升(降)温速度更高,墙体蓄热负荷更小,节能效果更明显,从热性能的角度而言,间歇用能模式下外墙内保温具有更强的适宜性。
The intermittent energy-using mode is represent asthe intermittent of time and space, which is different from the continually energy-using mode in extremely cold area, therefore a suitable type of thermal insulation systemneed to be selected.In this research, thermal characteristics of self-thermal insulation, exterior thermal insulation and internal thermal insulationunder the intermittent energy-using modewere analyzed through experiment. The results showed thatinternal insulation has ahigher heat reaction rate and lower heat storage under air-conditioning or heating environments,and more energy-saving. The thermal characteristics implied that internal thermal insulationshas was more suitable in intermittent energy-using area.
