摘　　要：提出了一种新型的与建筑一体化太阳能双效集热器系统,该系统有两种工作模式:被动采暖工作模式和集热水工作模式。由系统工作在被动采暖工作模式下的实验结果可以得到:系统房间内空气存在温度分层现象,测试期间上下位置最大温差为4.2℃,平均温差约为2.7℃;系统在被动采暖工作模式下工作时对房间温度的提高作用明显,实验测试结果显示,实验期间系统房间平均温度达到24.7℃,相对环境温度升高平均达到19.9℃。通过系统以自然循环方式工作在集热水工作模式下的实验测试结果,可以得到实验期间在集热水工作模式下系统的热效率为52.8%,集热器单位面积太阳得热为4.16MJ/m^2。A novel building integrated solar collector named dual-functional solar collector was proposed and designed, which was installed on the south-facing exterior wall of buildings to run in two independent operating modes： passive space heating in cold days, and solar water heating in hot days. Experiment study of the dual-function solar collector integrated with building was carried out in a hotbox. The experiment study on the novel system in space heating mode show that the air was stratified in the room and the indoor temperature was evidently enhanced. The experimental data show that during the period of measure from 9：00 to 17：00, the temperature difference between the top and bottom position was up to the maximum value of 4.2℃ and its mean value was about 2.7℃, and the mean indoor temperature was up to 24.7℃, while the mean ambient temperature was only 4.8℃. The experimental results on the novel system in water heating mode show that the thermal efficiency of collector achieved 52.8% and the solar heat gain was about 4.16MJ/m^2 by collector.
