Abstract

In this study, thermal efficiency of solar air collectors with trapezoidal and flat plate absorberis experimentally investigated. In the experiments, outside air temperature, global radiation, temperatures of the two different points on the absorber plate, air velocity and temperature at the collector outlet are measured. The thermal efficiency is calculated based on the measurements. Average thermal efficiency of solar air collector with trapezoidal absorber plate is 28.5 % while avarage thermal efficiency of solar air collector with flat absorber plate is 23.1 %. As a result, thermal efficiency of solar air collector with trapezoidal absorber plate is higher than that of solar air collector with flat absorber plate.

Özet

Bu çalışmada, trapez ve düz tip yutucu plakalı güneş enerjili hava kollektörlerin ısıl verimi deneysel olarak incelenmiştir. Deneylerde dış hava sıcaklığı, global ışınım, yutucu plaka üzerinde iki noktadan yüzey sıcaklığı, kollektör çıkış hava hızı ve sıcaklığı ölçülmüştür. Yapılan ölçümlere dayalı olarak ısıl verimleri hesaplanmıştır. Trapez yutucu plakalı kollektörün ortalama ısıl verimi % 28.5 iken düz yutucu plakalı kollektörün ısıl verimi ise % 23.1 olarak elde edilmiştir. Sonuç olarak trapez yutucu plakalı kollektörün, düz yutucu plakalı kollektöre göre ısıl veriminin daha yüksek olduğu belirlenmiştir.
