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 new double-effect solar collector system with integrated solar system was proposed. The system has two working modes: passive heating mode and hot water collecting mode. The experimental results of the system working in the passive heating mode can be obtained: the temperature of the air in the system room is stratified, the maximum temperature difference between the upper and lower positions during the test is 4.2 ℃ and the average temperature difference is about 2.7 ℃; the system works under the passive heating mode When the temperature of the room to enhance the role of obvious, experimental test results show that during the experiment the average room temperature reached 24.7 ℃, the relative increase in ambient temperature reached an average of 19.9 ℃. Through the experimental results of the system working in natural circulation mode in hot water collection mode, the thermal efficiency of the system under the hot water collection operation mode during the experiment is 52.8%, the solar thermal gain per unit area of the collector is 4.16MJ / m ~ 2.
