【摘要】 提出在现有的被动式太阳能集热墙的空气夹层中悬挂涂有选择性吸收涂层的百叶窗帘,组成新型结构的百叶型集热墙。利用可对比热箱实验平台,测试研究百叶型集热墙的集热性能,分析对比不同角度叶片对室内温度的影响。实验结果显示,在室内无热源情况下,叶片角度设置在45°时的集热效果最好,装有百叶型集热墙的房间的平均温度最高比普通房间高出12.6℃,能显著提高室内环境温度,改善室内热环境,降低室内热负荷。更多还原

【Abstract】 A novel version Trombe wall was proposed,which was installed a venetian blind in air gap that coveredselectively absorptive covering,forming venetian-type solar collector wall. Experiments and analysis were done about thethermal efficiency of Trombe wall with venetian structure,and the influence on indoor temperature in different bladeangle in the comparable hot-boxes experimental platform. The results showed that thermal performance was best when theblade was set at 45°,the average temperature of room with venetian-type solar collector wall was 12.6 ℃ higher than thatof normal room at maximum,the Trombe wall with venetian structure can raise room temperature,improve thermalenvironment and reduce the space heating load.更多还原
