【摘要】 设置集热蓄热墙是一种有效降低采暖能耗的被动式太阳能利用方式,不同形状、面积及墙地比的集热蓄热墙对建筑采暖的影响很大。文章以西宁市多层住宅为例,在南向卧室增设集热蓄热墙,实验结果表明:集热蓄热墙的面积越大,墙地比越高;形状尺寸越近似于正方形时,集热蓄热墙的节能效率越明显,同时室内温度越高。更多还原

【Abstract】 Installing Trombe Wall considered to be an effective utilization of passive solar energy, which could reducing energy consumption. The trombe wall of different shapes, areas, and wall-to-ground ratios have a great influence on building heating. In this paper, we installed Trombe Wall to south-facing bedrooms in multistoried buildings to study the heating effects. The experimental results showed that the wall was more energy-saving with higher indoor temperature when the Trombe Wall was larger, more closer to square with higher wall-to-ground ratio.更多还原
