为改善太阳能光伏光热(PV/T)系统的效率
在空冷型PV/T系统的冷却通道内加入折流板和旋流装置以强化换热
通过建立数值模型
综合考虑空气流动阻力的影响
分析了质量流量、折流板数量、旋流强度等对PV/T系统实际电效率及综合效率的影响。结果表明:随着冷却空气质量流量的增加
电效率和热效率均逐渐增大
但增幅减少;当质量流量从0.01 kg/s增加到0.05 kg/s时
电效率上升约0.65百分点;PV/T系统的实际电效率和实际综合效率随空气质量流量增加先增加后减少
当空气质量流量分别为0.02 kg/s和0.04 kg/s时
实际电效率和实际综合效率分别达到最大值;在通道腔室加装旋流风扇
可有效提升系统的综合效率
当旋流强度等于3时
PV/T系统的综合效率可达79.09%;在相同旋流强度下
旋流作用对低入口质量流量系统的提升作用相较于高质量流量下更明显。
In order to improve the efficiency of solar PV/T systems
baffle plates and swirl devices were added to the cooling channels of an air-cooled PV/T system to enhance heat transfer. A numerical model was established
and the influence of air flow resistance was comprehensively considered. The effects of such factors as mass flow rate
number of baffle plates
swirl intensity on the actual electrical efficiency and comprehensive efficiency of PV/T systems were analyzed. Results show that with the increase of the mass flow rate of the cooling air
both electrical efficiency and thermal efficiency gradually increase
but the increase rate decreases. When the mass flow rate increases from 0.01 kg/s to 0.05 kg/s
the electrical efficiency rises by approximately 0.65 percentage rates.The actual electrical efficiency and the actual comprehensive efficiency of the PV/T system first increase and then decrease with the increase of the air mass flow rate. When the air mass flow rate is 0.02 kg/s and 0.04 kg/s
the actual electrical efficiency and the actual comprehensive efficiency reach the maximum values respectively. Adding a swirl fan to the channel chamber can effectively improve the comprehensive efficiency of the system. When the swirl intensity is 3
the overall efficiency of the PV/T system can reach 79.09%. Under the same swirl intensity
the lifting effect of swirl on low inlet mass flow systems is more obvious compared with that under a high mass flow.
