    Effect to the performance of different type absorber plates on the solar air collectors
    (2008) Gedik, E.; Keçebas, A.; Öz, E.S.
    In this study, two different types of solar air collectors, zigzagged absorber surface type and flat absorber surface type called Model I and Model II respectively, have been constructed and examined experimentally. Experiments were made between 10.00-17.00 hours of August and September under Karabük conditions and tests were carried out for five days. Energy and exergy performances have been computed using the experimental data. At the end of the study, it showed that energy and exergy performances of the Model II solar air collector were better than Model I solar air collector. While energy and exergy performances of the Model II solar air collector was %46,5 and %1,35, Model I solar air collector performance was %32,72 and %1,35.

    Experimental investigation of collector efficiencies on separated and connected heat pipes
    (2008) Acar, B.; Öz, E.S.; Gedik, E.
    The aim of study is to determine the effect of heat pipe systems to collector efficiency at solar collectors used in supplying hot water. For this purpose, two different collectors as the connected heat pipe and separated heat pipe have been produced. The experimental studies with the collectors have been conducted in Karabük city environment. The experiments have been completed in six days. The collector efficiencies have been calculated by measuring temperature of water tanks, ambient temperature and solar radiation in both collectors. As a result, while average efficiency of the connected heat pipe collector is 57.6%, average efficiency of the separated heat pipe collector is 48.5%.
