Özet:

 The proposed study aims to examine the performance of a combined solar power generation system. The system comprises photovoltaicthermal PVT panels, a pump, a capacitor, and a turbine. R744, R170, and R41 were used as working fluids. The Engineering Equation Solver EES program is used to perform the performance evaluation of the system. Comparative thermodynamic analyzes and parametric studies are conducted to determine the best fluid. The results demonstrate that the highest power production rate of 0.4669 kW is calculated for the cycle using R41, followed by R744. Additionally, the highest energy efficiency and efficiency of exergy are calculated when R41 fluid is used, while the lowest energy and efficiency of exergy are calculated when R170 fluid is used. R170 is determined to have the highest irreversibility, with a destruction rate of exergy of 20.57 kW. According to the results of this analysis, the best working fluid was determined as R41. Parametric analyzes were performed to determine the effects of P1P2 and solar irradiation on the performance of the system, like power production, efficiency of energy, destruction of exergy, and efficiency of exergy. It has been shown that power generation, energy efficiency, and efficiency of exergy increase with P1P2 and solar irradiation for all fluids. While the destruction of exergy decreases with increasing pressure ratio, exergy destruction increases with increasing solar irradiation.

 Bu çalışmanın amacı, birleşik bir güneş enerjisi üretim sisteminin performansını incelemektir. Sistem, FotovoltaikTermal PVT paneller, bir pompa, bir kondansatör ve bir türbinden oluşmaktadır. Çalışma akışkanı olarak R744, R170 ve R41 kullanılmıştır. Sistemin performans değerlendirmesini gerçekleştirmek için Engineering Equation Solver EES yazılım programı kullanılmaktadır. En iyi çalışan akışkanı belirlemek için karşılaştırmalı termodinamik analizler ve parametrik çalışmalar yapılır. Sonuçlar, en yüksek güç üretim oranının 0.4669 kW ile R41 ve ardından R744 kullanılan çevrim için hesaplandığını göstermektedir. Ayrıca, en yüksek enerji ve ekserji verimi R41 akışkanı kullanıldığında, en düşük enerji ve ekserji verimi ise R170 akışkanı kullanıldığında hesaplanmıştır. R170in, 20.57 kW ekserji yok etme oranı ile en yüksek tersinmezliğe sahip olduğu bulunmuştur. Bu analiz sonuçlarına göre en iyi çalışma akışkanı R41 olarak belirlenmiştir. P1P2 ve güneş ışınımının sistem performansı üzerindeki güç üretimi, enerji verimliliği, ekserjinin yok edilmesi ve ekserji verimliliği gibi etkilerini belirlemek için parametrik analizler yapılmıştır. Tüm akışkanlar için P1P2 ve güneş ışınımı ile güç üretim hızı, enerji verimliliği ve ekserji veriminin arttığı gösterilmiştir. Artan basınç oranı ile ekserji yıkımı azalırken, artan güneş ışınımı ile ekserji yıkımı artmaktadır.
