摘要
针对冷却通道位于光伏板上侧的空气冷却型太阳能光伏光热(PV/T)系统,采用验证后的数值模型模拟研究冷却通道长度、高度及空气入口流速等设计参数对系统性能的影响.结果表明:在寒冷地区夏季典型日工况下,随着气象参数的变化,最佳空气入口流速范围为0.8~3.2 m·s^-1,对应的系统效率变化范围为14.61%~15.24%.
For the air-cooled photovoltaic/thermal(PV/T)system with the cooling channel located on the upper side of the photovoltaic panel,the influence of the designed parameters including the length and height of the air-cooled channel and the air inlet velocity on the system performance were simulated and studied by the validated numerical model.The results indicate that with the meteorological conditions changing under the typical daily working conditions in summer in cold region,the optimal air inlet velocity range is 0.8-3.2 m·s^-1,and the corresponding system exergy efficiency change range is 14.61%-15.24%.
