AbstractUsing the power of the sun is becoming more and more popular to generate the heat besides needing electricity. Solar air heating systems which are used for supplemental heating are extremely effective and most economical way of the building heating. In addition, solar air heating systems are important in view of CO2 reduction strategies since these systems decreases the greenhouse gas emissions as a result of reducing the using of fossil-based sources. The performances of these systems are depending on their designs and operating parameters. In the presented paper, three different types of solar air heaters were designed and analyzed in the thermally by using computational fluid dynamics (CFD). The solar radiation values were given by the Solar Load module in the ANSYS Fluent programme. Mesh independence was taken into account in numerical solutions. The results of three different designs were thermally interpreted and the yield values of the designs were compared.
