摘　　要：为提高太阳房中的太阳能利用率,针对在冬季反射更多阳光至室内的太阳能百叶窗和主被动结合式太阳房展开研究。借助太阳能百叶窗得热模型,确定最佳的百叶角度。建立耦合太阳能百叶窗的主被动结合式太阳房FLUENT模型,分析太阳能百叶窗贴膜材料和室外太阳辐射环境改变对太阳房内温度影响的变化规律。研究得出在鄂尔多斯地区,当进入室内的得热量最大时,对应的百叶倾角约为10°。在室外温度为3.8℃,太阳辐射强度为910 W/m^(2)的工况下,叶片贴膜材料的反射率增加0.1,对应的室内温度提高约0.11℃。室外温度降低2℃,辐射强度降低102 W/m^(2)时,太阳房内温度均值降低约1.15℃。研究成果为太阳能百叶窗在主被动结合式太阳房中的应用提供了理论指导。Aiming at improving the utilization rate of solar energy in the solar house,this paper studies the solar shutter which reflect more sunlight indoors in winter and active-passive solar house.With the help of the solar energy shutter heat gain model,determine the best shutter angle.The active-passive combined solar house coupled with solar shutter is established in FLUENT.The effects of solar shutter venetian materials and outdoor solar radiation environment on the indoor temperature are analyzed.The research shows that in Ordos area,when the heat gain into the room is the largest,the corresponding shutter angle is about 10°.When the outdoor temperature is 3.8℃and the solar radiation intensity is 910 W/m^(2),the reflectivity of shutter venetian increases by 0.1,and the indoor temperature increases by about 0.11℃.When the outdoor temperature decreases by 2℃and the radiation intensity decreases by 102 W/m^(2),the average temperature in the solar room decreases by about 1.15℃.The research results of this paper provide theoretical guidance for the application of solar louvers in active-passive combined solar houses.
