Evaluation of Thermal Environment Around the Blind on Non-Uniform Radiant Fields A CFD Simulation of Heat Transfer Distribution Near the Blinds

The purpose of this research is to evaluate the indoor thermal environment under the solar shading environment. In this report, it experimented in the room to which the blind was shut to confirm the indoor thermal environment. Afterwards, the CFD analysis based on the experiment was done. And, the accuracy of the analysis was confirmed by compared with measurement results. In the experiment, it was confirmed that heat had collected in the hollow layer between the window and the blind. And, the heat leaked indoors. There was a difference in top and bottom indoor temperature distribution for the leakage of heat. Moreover, it was confirmed that the indoor temperature changed according to the slat angle of the blind. In the analysis, the temperature of the air in the room was roughly corresponding to experimental measurements. However, when the wall temperature was analyzed, the problem that had to examined in the future was discovered.
