利用实验数据验证了内嵌于建筑能量与环境综合模拟软件ESP-r的光伏窗传热、采光、太阳能发电的数学模型,自然采光即室内照度的数学模型采用了daylight coefficient模型,利用验证过的数学模型模拟了位于香港地区的典型办公建筑装配单层吸收窗、单层光伏窗、双层通风光伏窗时的能量性能。结果表明:双层通风光伏窗的综合能量性能最好,窗体的太阳能发电量和综合能量性能受窗体朝向的影响很大;在香港地区,西向光伏窗的能量性能最好、发电量最大。
The mathematical model of heat transfer, lighting and solar power generation in photovoltaic windows embedded in ESP-r of building energy and environment was validated by experimental data. The daylight coefficient model was adopted in the mathematical model of natural light illumination, that is indoor illumination. The mathematical model simulates the energy performance of a typical office building in Hong Kong equipped with single-layer absorber windows, single-layer photovoltaic windows and double-deck photovoltaic windows. The results show that the overall energy performance of the double-decked photovoltaic window is the best, and the solar energy yield and overall energy performance of the form are greatly affected by the orientation of the window. In Hong Kong, the west-facing photovoltaic window has the best energy performance and the largest power generation .
