摘要:
针对被动太阳能窗白天太阳得热要求的太阳总透射比大和夜间防止失热希望的传热系数小的矛盾问题,开发了一种热工参数可变的被动太阳能窗,实现了窗户传热系数U和太阳得热系数SHGC阶跃可变.采用WINDOW和THERM软件对窗户的热工性能进行了模拟与优化,给出了不同玻璃组合形式、窗框型材及窗框比下的热工性能参数,并通过第三方检测对模拟结果进行了验证.结果表明:模拟相对误差约为4%,可满足工程应用精度要求; 对于热工参数可变的被动太阳能窗(G3玻璃系统),白天内窗扇开启时,SHGC升高至0.69,进入室内的太阳辐射得热增加82%,可有效提高太阳辐射得热量; 夜晚内窗扇关闭时,窗户U值降低至1.66 W/(m2·K),可有效减少窗户夜晚的散热量.
Abstract:
Aiming at the contradiction between the high total solar transmittance required by the passive solar window for solar heat gain during the day and the small heat transfer coefficient required to prevent heat loss at night, a passive solar window with variable thermal parameters was developed to achieve a step change in the heat transfer coefficient U and the solar heat gain coefficient SHGC of the window. WINDOW and THERM software were used to simulate and optimize the thermal performance of the window, and the thermal performance parameters under different glass combination forms, window frame profiles and window frame ratios were given. The simulation results were verified by third-party testing. The results show that the relative error of simulation is about 4%, which can meet the accuracy requirements of engineering applications. For passive solar window with variable thermal parameters(G3 glass system), when the window sashes are opened during the day, the SHGC increases to 0.69, and the solar radiation entering the room increases by 82%, which means that the solar heat gain is effectively increased. When the window sashes are closed at night, the U is reduced to 1.66 W/(m2·K), which can effectively reduce the heat dissipation of the window at night.
