摘要

随着世界向更可持续的未来转变,太阳能已成为传统能源的卓越且经济可行的替代品,并得到广泛采用。本研究提出了一种反向圆流射流冲击(RCFJI),旨在改善双面PVT收集器的性能。使用太阳能模拟器进行室内实验,以评估RCFJI双面PVT收集器的能量、火用和经济效率。该研究使用500-900W/m2的太阳辐照度和0.01-0.14kg/s的质量流速进行。就能量性能而言,在500W/m2的太阳辐照度下,实现的最高光伏效率为11.38%,而在900W/m2下,实现了61.4%的最高热效率,两者都是在0.14kg/s的质量流量下获得的。关于火用性能,在0.14kg/s的900W/m2下获得的最高光伏火用为47.27W,而在0.01kg/s的900 W/m2下得到的最高热火用为9.67W。总的来说,更高的太阳辐照度对于能量和火用性能来说是更可取的。同时,从经济角度来看,较低的太阳辐照度是可取的。根据研究结果,最佳质量流量为0.06kg/s。

Performance and economic analysis of a reversed circular flow jet impingement bifacial PVT solar collector
As the world shifts towards a more sustainable future, solar energy has emerged as a preeminent and economically feasible alternative to traditional energy sources, gaining widespread adoption. This study presents a reversed circular flow jet impingement (RCFJI) which aims to improve the performance of a bifacial PVT collector. An indoor experiment using a solar simulator to assess the energy, exergy, and economic efficiency of a RCFJI bifacial PVT collector. The study was carried out using a solar irradiance ranging from 500-900W/m2 and a mass flow rate between 0.01-0.14 kg/s. Energy performance-wise, the highest photovoltaic efficiency achieved was 11.38% at solar irradiance of 500 W/m2, while the highest thermal efficiency achieved was 61.4% under 900 W/m2, both obtained at 0.14 kg/s mass flow rate. Regarding exergy performance, the highest photovoltaic exergy obtained was 47.27 W under 900 W/m2 at 0.14 kg/s, while the highest thermal exergy was 9.67 W at 900 W/m2 at 0.01 kg/s. Overall, higher solar irradiance is more desirable for energy and exergy performance. Meanwhile, economic point of view, lower solar irradiance is preferable. Based on the findings, the optimal mass flow rate was 0.06 kg/s.
