作为一种新型的太阳能光热建筑一体化系统，与建筑一体化太阳能双效集热器系统具有2种工作模式：在冬季的被动采暖工作模式和在其他无需供暖的时期的集热水工作模式。针对系统以自然循环方式工作的集热水工作模式，进一步建立了系统房间带窗结构时的理论计算模型。以设计的虚拟房间为对象，通过理论分析，研究了在夏季季节运行时，系统的工作水量和背板保温层设计对系统集热水性能和对建筑的热影响的不同情况。结果显示：对于系统设计来说，背板保温层的适宜设计厚度约在0.05 m，工作水量在夏季运行时的适宜量约是40～50 kg/m2；系统在夏季工作时可以在一定程度上降低房间的冷负荷，不会造成传统被动采暖系统常遇到的夏季建筑过热问题。

In this study,a validated dynamic numerical model was used to make a parametric study on the no-vel system for the warm period operation under the water heating mode with natural circulation. For thermal insula-tion of backboard and operating water weight were two great important factors of the novel system,their influence on the water heating performance and the thermal effect on the building environment were calculated and analyzed. The case results showed that for the novel system at the water heating mode with natural circulation under the climate condition ,the operating water weight within 40-50 kg/m2 was appropriate in summer and the appropriate thickness of the thermal insulation of backboard was around 0. 05 m. By comparing with the thermal loads of rooms with and without the collector,it can be seen that the thermal effect is evitable in summer.
