论文摘要
建筑物的合理热管理对于减少总体初级能源消耗至关重要。智能窗口是有希望的系统，可以节省大部分能源。在这里，我们介绍了一个双层玻璃系统，由热质金属 - 金属绝缘体过渡材料和一个被气隙隔开的玻璃层，该玻璃层能够从隔离阶段切换到其导电阶段，这要归功于分离间隙中的温室效应。我们还表明，与传统的双层玻璃相比，这种被动系统可以将传入的热通量减少30％，同时在75％的可见光谱中保持透射率约为0.35。
The rational thermal management of buildings is of major importance for the reduction of the overall primary energy consumption. Smart windows are promising systems which could save a significant part of this energy. Here we introduce a double glazing system made with a thermochromic metal-insulator transition material and a glass layer separated by an air gap which is able to switch from its insulating to its conducting phase thanks to the greenhouse effect occuring in the separation gap. We also show that this passive system can reduce the incoming heat flux by 30% in comparison with a traditional double glazing while maintaining the transmittance around 0.35 over 75% of visible spectrum.
