The purpose of this study is to examine the feasibility of radiant heating & cooling system by means of field measurements and computational fluid dynamics (CFD) simulations coupled with convection and radiation. Radiant panels can be operated below the dewpoint temperature and can remove humidity from the air by condensation. It is necessary to model the radiant panel in the shape of actual use to understand the thermal characteristics of the radiant panel. In the first step of this study, the indoor thermal environment of the real scale space, which is air-conditioned by radiant heating system, is analyzed by field measurement and CFD. With comparing the both results, the validity of the CFD method is examined from the practical point of view. In case of the multi panel model, the influence of convection is greater. The radiant panel of actual use is not real “Radiant Panel” because ASHRAE named it which radiant heat transfer rate of the overall heat transfer rate is more than 50%.
