Vorteks Tüpü Destekli Soğutmanın PV Panellerin Elektriksel Performansı Üzerindeki Etkisi

Öz

Bu çalışmada, fotovoltaik (PV) panellerde sıcaklık artışına bağlı elektriksel performans kayıplarını azaltmak amacıyla Ranque-Hilsch vorteks tüpü destekli aktif hava soğutma yöntemi deneysel olarak incelenmiştir. Geleneksel fan veya blower destekli hava soğutma sistemlerinden farklı olarak, vorteks tüpü tarafından üretilen düşük sıcaklıklı hava panelin arka yüzeyine yerleştirilen alüminyum soğutma bloklarına yönlendirilmiştir. Aynı dış ortam koşullarında iki özdeş PV panel test edilmiş; panellerden biri vorteks tüpü ile soğutulurken diğeri referans panel olarak kullanılmıştır. Ayrıca, atık basınçlı havanın kullanımı önerilen sistemin uygulama potansiyelini gösteren alternatif bir senaryo olarak değerlendirilmiştir. Vorteks tüpün etkili çalışma aralıklarında maksimum sıcaklık düşüşü 8,22 °C, en yüksek ölçülen güç artışı ise %6,81 olarak elde edilmiştir. Sonuçlar, vorteks tüpü destekli soğutmanın PV panel elektriksel performansını iyileştirebildiğini göstermektedir.

Effect of Vortex Tube-Assisted Cooling on the Electrical Performance of PV Panels

Öz

In this study, an active air cooling method assisted by a Ranque-Hilsch vortex tube was experimentally investigated to reduce temperature-induced electrical performance losses in photovoltaic (PV) panels. Unlike conventional fan or blower-assisted air cooling systems, low-temperature air produced by the vortex tube was directed to aluminum cooling blocks mounted on the rear surface of the panel. Two identical PV panels were tested under the same outdoor conditions; one was cooled using the vortex tube, while the other was used as the reference panel. In addition, the use of waste compressed air was evaluated as an alternative application scenario, indicating the practical potential of the proposed system. During the effective operating intervals, the maximum temperature reduction reached 8.22 °C, while the highest measured power increase was 6.81%. The results show that vortex tube-assisted cooling can improve PV panel electrical performance.
