摘要
文章提出了一种新型热管式太阳能光伏光热(PV/T)一体化系统,并提出了能够表征主动式PV/T系统能量收益的参数—实际能量收益率。在同一工况下,对热管式PV/T系统和PV系统进行测试研究,分析不同影响因素对热管式PV/T系统光电转化效率、光热转化效率及实际能量收益率的影响规律。研究结果表明:当热管式PV/T系统的循环流量为320 L/h时,该系统的实际能量收益率最大;同一工质流量下,光热转化效率对热管式PV/T系统实际能量收益率的影响远大于光电转化效率;热管式PV/T系统的实际能量收益率比PV系统高29.09%。
This paper proposes a new type of heat-pipe solar hybrid photovoltaic-thermal（PV/T）system, and proposes a parameter that can characterize the energy gain of the active PV/T systemthe actual energy yield efficiency. Under the same working conditions, the efficiency PV/T system and PV system were tested and analyzed. The influences of different influencing factors on the photoelectric conversion efficiency, thermal conversion efficiency and actual energy yield efficiency of the heat pipe PV/T system were analyzed. The results show that the working fluid flow rate of the heat pipe PV/T system is 320 L/h and get the maximum actual energy yield efficiency. Under the same working medium flow, the effect thermal conversion efficiency on the actual energy yield rate of heat pipe PV/T system is much greater than that of photoelectric conversion efficiency. The actual energy yield efficiency of heat pipe PV/T system is 29.09% higher than PV system.
