摘要
通过试验和MQMC软件模拟,研究了光伏玻璃、电控调光玻璃的透光率、相对位置对产能智能外窗玻璃光学与热工性能的影响,进而确定其优化配置方案及性能水平。结果表明,使用光伏玻璃和电控调光玻璃可以阻挡太阳热量和防止眩光,相比于超白玻璃,光伏基板玻璃的太阳能总透射比降低40%以上、可见光透射比降低54%以上,调光膜的太阳能总透射比降低12%以上、可见光透射比降低14%以上;光伏玻璃置于室外侧、调光膜置于3面或4面时,产能智能外窗玻璃的光学与热工性能相对较优;与普通三玻两腔外窗玻璃和Low-E玻璃相比,采用光伏玻璃加调光玻璃时,外窗玻璃的紫外线透射比、可见光透射比、太阳能总透射比、遮阳系数大幅减小。
The optical and thermal properties of power-generating intelligent exterior window glass were studied by testing and simulation with the MQMC software,and configuration and performance level of the power-generating intelligent exterior window glass were determined.The results show that the use of photovoltaic glass and electrically controlled dim glass can block solar heat and prevent glare.Compared with ultra-white glass,the total solar transmittance of photovoltaic substrate glass decreases by more than 40%,and the visible light transmittance decreases by more than 54%.The total solar transmittance of the dimming film decreases by more than 12%,and the visible light transmittance decreases by more than 14%.When the photovoltaic glass is placed on the outdoor side and electrochromic film is placed on surface 3 or 4,the optical and thermal properties of the power-generating intelligent exterior window glass are relatively better.Compared with triple-glazed double-cavity exterior window glass and Low-E glass,the use of photovoltaic glass and dimming glass significantly reduces the ultraviolet transmittance,visible light transmittance,total solar transmittance,and shading coefficient of the exterior window glass.
