| 摘 要： | 对空心墙体的静态热阻计算考虑了对流和辐射对热阻的影响,并用非稳态传热理论和计算机模拟分析的方法,利用传递函数法求解新型节能空心墙体的传热过程,计算某建筑物的围护结构(传统实心墙体和新型空心墙体)的全年逐时能耗和总能耗,并根据计算结果进行节能分析和经济性分析,得出:建筑物采用节能空心墙体与传统实心墙体相比,夏季节能27 19%,冬季节能23 92%,其投资可在10a内回收。

| Abstract: | In consideration of the effect of convection and radiation on steady thermal resistance, the steady thermal resistance is calculated. With method of unsteady-heat transfer theory and computer simulating analysis, heat transfer of new type energy-saving hollow wall is calculated in this paper. By calculating, the year-round and total energy consumption of building (both conventional wall and new hollow wall) has been gained, and on the basis of the results of calculations, saving energy and economic results are analyzed. In this paper such a conclusion is reached that compared with conventional wall, new hollow wall can save 27.19% energy in summer and 23.92% energy in winter. Its cost can be returned within 10 years using energy-saving hollow wall in building, |
