Abstract

In this study, a numerical model was developed to analyze the thermal behavior of a panel type (PKP) aluminum radiator used for space heating. The developed model was applied to a slice of the radiator and, convection and radiation effects were included in the calculations. Model accuracy tests were performed in the test room located in the Thermal Sciences Laboratory of the Mechanical Engineering Department of the Faculty of Engineering at Gazi University, using the experimental results performed according to the TS EN 442 standard on the market equivalent of the analyzed radiator. The test room was equipped according to the ANSI/ASHRAE-138 standard and made suitable with the EN 442 radiator test. The numerical analysis results showed that; 600-800-1100-1400 W thermal power can be obtained for 30-40-50-60oC temperature differences using the radiator under study and the heat transfer coefficient of the radiator is an average of 50 W/m2K.
