摘　　要：提出建立了在现有Trombe墙的空气夹层中悬挂百叶窗帘的百叶型太阳能集热墙,搭建了带有百叶型集热墙的可对比热箱实验平台,对百叶型集热墙的集热效率进行了测试和分析,实验结果显示,在冬季时,百叶型集热墙的瞬时集热效率最高能达41%,平均集热效率在30%左右,该研究表明新型百叶型集热墙能显著的提高室内环境温度,改善室内热环境,降低室内制热负荷。A novel version Trombe wall with venetian structure was proposed. Building the comparable hot--boxes constructed with Trombe wall with venetian structure. Experiments and analysis was done about the thermal efficiency of Trombe wall with venetian structure, the results showed that the maximum instantaneous thermal efficiency is 41%, average thermal efficiency is about 25%, means that the Trombe wall with venetian structure can raise room temperature, improve thermal environ- ment and reduce the space heating load.
