Konik yoğunlaştırmalı bir güneş enerjili hava ısıtıcının verimine farklı absorber yüzey kullanımının etkisi

Bu çalışmada, çift geçişli hava akış kanalında dolgu malzemesi bulunan yeni dizayn edilmiş bir konik yoğunlaştırıcılı hava ısıtıcının termal performansına farklı absorber yüzey kullanımının etkisi incelendi. Bu amaçla, standart siyah boyalı bakır boru, seçici yüzey ve yapay olarak pürüzlendirilmiş absorber yüzeyleri ayrı ayrı kullanıldı. En yüksek termal verim seçici yüzey kullanımı ile elde edildi.

Effect of various absorber surfaces on the efficiency of solar air heater with conical concentrator

In this study, the effects of various absorber surfaces on the thermal performance of a newly designed solar air heater with conical concentrator, including packings inside two-pass airflow channel of the absorber were investigated. For this purpose, in addition to standart black-painted copper tube, absorber with selective surface or artificially roughened surface was used separately as absorber surfaces. The highest thermal efficiency was obtained by using the absorber with selective surface.
