Radiant systems provide better thermal comfort conditions than traditional heating and cooling systems, as well as low energy consumption. The performance of radiant panel systems in terms of energy and exergy have attracted the attention of the academicians around the world. In this study, the effect of the wall mounted radiant cooling system on thermal comfort was investigated numerically. For this purpose, the coolant temperature inside the radiant panels was defined as 18 degrees C, 20 degrees C and 22 degrees C respectively and the results were compared according to the PMV-PPD parameters. It has been found that all cases fulfilled the thermal comfort conditions specified in ASHRAE 55 standard and the best conditions were obtained at 20 degrees C water temperature.
