The radiant ceiling cooling panel (RCCP) system has been proved thermally efficient and economically but it cannot prevent hot air stream from window individually. Therefore, this study integrated a forced ventilation system with a new RCCP with a segmented and concave surface. In this study, a three-dimensional CFD model is developed and validated with the experimental results. Whereas, the indoor thermal comfort and cooling performance of the proposed coupling are numerically investigated, analyzed, and compared with the RCCP system with ventilation. The results show that the ventilation system is effective to prevent the hot air stream, and it also enhanced the cooling performance of the RCCP. Furthermore, the parametric study and sensitivity analysis are carried out to optimize the operating condition of these two systems to maximize the cooling capacity of the RCCP system and increases the panel surface temperature to mitigate the possible condensation.
