Abstract

In this study, the thermal performance of evacuated tube solar collector (ETSC) with reflective surface and availability of system was investigated for steam generation. For this purpose, the compound parabolic solar collector has been designed and manufactured. In order to observe system performance, experiments were carried out in different outdoor conditions. During the experiments, the feed water and steam outlet temperatures, the ambient temperature, the inner tube surface temperature, solar radiation and amount of steam generation were measured using thermocuples and pyranometer. In order to determine the heat loss from absorber surface to the enviroment, mathematical model was created with the help of experimental data and heat loss coefficient were calculated. Comparing of the experiental and analytical datas, the suitability of the ETSC with inner tube for steam genration and thermal efficeny was evaluated.

Özet

Bu çalışmada, yansıtıcı yüzey kullanılan iç borulu vakum tüplü güneş toplayıcısınınısıl performansı incelenerek, buhar üretiminde kullanılabilirliği araştırılmıştır. Buamaçla bütünleşik parabolik bir güneş toplayıcısının tasarım ve imalatı gerçekleştirilmiştir. Sistem performansını gözlemlemek için, farklı dış ortam koşullarındadeneyler yapılmıştır. Deneyler sırasında besleme suyu ve buhar çıkış sıcaklıkları,çevre sıcaklığı, vakum tüp dış yüzey sıcaklığı, iç boru yüzey sıcaklığı, güneş ışınımdeğeri ve üretilen buhar miktarı, ısıl çiftler ve piranometre kullanılarak ölçülmüştür. Yutucu yüzeyden çevreye olan ısı kaybını belirlemek için deneysel veriler yardımıyla matematiksel model oluşturulmuş ve ısı kayıp katsayıları hesaplanmıştır. Bumodel sonucunda elde edilen sayısal sonuçlar deneysel verilerle karşılaştırılarak,yansıtıcılı iç borulu güneş toplayıcısının ısıl verimi ve buhar üretimine uygunluğudeğerlendirilmiştir.
