摘要
对在定出口水温工况下运行的低倍聚光光伏/光热(LCPV/T)系统进行理论与实验研究,通过理论结果与实验结果的对比,对此系统进行性能分析,并讨论其影响因素。实验结果表明,理论值与实验值存在一定的差异,在定出口水温(323.15 K)的条件下,该文所研究的LCPV/T系统最大热效率为59.65%,电效率为19.48%,热功率为2144 W,电功率为574 W。
Low concentration photovoltaic/thermal technology(LCPV/T)can supply both heat and power. Meanwhile,it has the advantage of low cost and less land occupation,therefore,the LCPV/T technology is suitable for integrating with building. In this study,The performance of a LC-PV/T system under fix outlet temperature was carried out,numerically and experimentally. Comparing the simulated results with the experimental results,the performance of the system is analyzed,and the influencing factors are discussed. The results show that some differences between the simulated results and experimental results. When the outlet temperature is 323.15 K consistently,the maximum thermal efficiency of the system is 59.65%,the electric efficiency is 19.48%,the thermal power is 2144 W,and the electric power is 574 W.
