Optimization of Control Parameters Affecting Panel Surface Temperature in Air-Cooled PVT Panels

Abstract

Panel surface temperature has a significant effect on panel performance parameters. The tremendous increase in panel surface temperature, especially seen in the summer months, leads to significant reductions in panel efficiency. In this study, fins to the air-cooled PVT system was added. The effect of the design parameters (surface temperature of back of the panel, airflow velocity, depth of duct, fin configuration, fins materials) on the panel surface temperature, fin temperature and outlet temperature was investigated using the Taguchi Method, and the optimal design combination was determined. In addition, the images obtained by ANSYS FLUENT analysis were analyzed. In our study, monocrystalline panels were used. Experiments were conducted for the frequent and sparse configurations of the fins made of copper, aluminum and brass materials. It was observed that while most effective parameters for panel surface temperature, fin temperature and outlet temperature were the fin configuration, fan speed and duct depth. The optimal design combination was found to be A2-B3-C2-D3-E2 for panel surface temperature, A1-B1-C3-D2-E2 for fin temperature, A1-B1-C3-D2-E3 for outlet temperature.

Hava Soğutmalı PVT Panellerde Panel Yüzey Sıcaklığını Etkileyen Kontrol Parametrelerinin Optimizasyonu

Abstract

Panel yüzey sıcaklığı PV panelin performans parametreleri üzerinde çok önemli etkiye sahiptir. Özellikle yaz aylarında görülen panel yüzey sıcaklığındaki aşırı yükselme panel veriminde ciddi düşüşlere neden olur. Bu olumsuz durum panel yüzeyi soğutularak minimize edilebilir. Bu çalışmada, hava soğutmalı PVT sistemine kanatçıklar eklendi. Kontrol parametrelerinin (panelin arka yüzey sıcaklığı, fan hızı, kanal derinliği, kanatçık konfigürasyonu, kanatçık malzemesi) panel yüzey sıcaklığına, kanatçık sıcaklığına ve çıkış sıcaklığına etkisi Taguchi Yöntemi kullanılarak incelendi ve en uygun tasarım kombinasyonu belirlendi. Ayrıca ANSYS FLUENT analizi ile elde edilen görüntüler analiz edildi. Çalışmamızda monokristal panel kullanıldı. Bakır, alüminyum ve pirinç malzemelerden yapılmış kanatçıkların sık ve seyrek konfigürasyonları için deneyler yapıldı. Panel yüzey sıcaklığı, kanatçık sıcaklığı ve çıkış sıcaklığı için en etkili parametrelerin kanatçık konfigürasyonu, fan hızı ve kanal derinliği olduğu görüldü. Optimal tasarım kombinasyonu, panel yüzey sıcaklığı için A2-B3-C2-D3-E2 olduğu, kanatçık sıcaklığı için A1-B1-C3-D2-E2 olduğu, çıkış sıcaklığı için A1-B1-C3-D2-E3 olduğu bulundu.
