在太原地区建立光伏窗热电性能实验平台,以此来研究混合送风系统与分层空调系统运行时,室内气流温度和送风速度对非晶硅光伏窗热电性能的影响.研究结果表明:对于混合送风系统与分层空调系统而言,随着室内气流温度的逐渐降低,光伏窗发电性能逐渐提高,但光伏窗得热量也逐渐增加;空调送风速度的增大会使光伏窗的发电性能得到提升,但送风速度对光伏窗发电性能的影响要小于室内气流温度;当室内气流温度和送风速度相同时,分层空调系统的制冷效果远优于混合送风系统,并使光伏窗的发电性能相对提高10.5%,得热量相对减少37.4%.%In this paper, the influence of different indoor air distributions, named mixing ventilation system (MV) and displacement ventilation system (DV), on the thermal and power generation performance of photovoltaic (PV) window are experimentally studied, in terms of space air-conditioning temperature and supply air velocity. The results indicate that as the space air-conditioning temperature decreased in both typical indoor air distributions, the power generation of the PV window is gradually increased, but the heat gain of PV window is also increased. Increasing the air supply velocity is beneficial to increase the power generation of PV windows, however, the effect is not as strong as that caused by space air-conditioning temperature. Compared with the MV system, the DV system is much better in the cooling of PV window. As a result of that, in the DV system the power generation of PV window is 10.5%higher and the heat gain of PV window is 37.4%less than that of in the MV system.
