The warm draft that floats from the window has an unfavorable influence on the indoor thermal comfort condition, which heated the indoor air temperature. Therefore, an integrated cooling system combined novel free-suspended ceiling radiant cooling panel (CRCP) with a wall Attached Ventilation (WAV) system is proposed and investigated by using a three-dimensional conjugated computational fluid dynamic (CFD). Two different WAV systems (ceiling inlet/ceiling outlet; ceiling inlet/floor outlet) are examined under various operating conditions. Moreover, the surface response, sensitivity analysis, and optimization of the system's operating condition are carried out via the ANSYS Design Explorer tool. In conclusion, adding the ventilation system with a ceiling inlet and ceiling outlet is more effective than installing a ceiling inlet and a floor outlet. Moreover, the operating conditions with the inlet air velocity of 0.164 m/s, inlet air temperature of 25 °C, and panel surface temperature of 23 °C are selected as the optimum design. Under this condition, the system can prevent warm draft effectively and achieve better thermal comfort using a lower ventilation flow rate, higher ventilation temperature, and higher panel surface temperatures. Thus, it also shows a significant potential of energy-saving accordingly.

从窗户上飘来的温暖的气流对室内的热舒适条件产生了不利的影响，室内的热舒适条件加热了室内空气的温度。因此，提出了一种集成式冷却系统，该系统结合了新型的自由悬挂式天花板辐射冷却面板（CRCP）和壁挂式通风（WAV）系统，并使用三维共轭计算流体动力学（CFD）进行了研究。两种不同的WAV在各种操作条件下检查系统（天花板入口/天花板出口；天花板入口/地板出口）。此外，可通过ANSYS Design Explorer工具执行表面响应，灵敏度分析和系统运行条件的优化。总之，增加通风系统以及天花板入口和天花板出口比安装天花板入口和地板出口更有效。此外，最佳的设计是选择进气速度为0.164 m / s，进气温度为25°C，面板表面温度为23°C的工作条件。在这种情况下，该系统可以通过较低的通风量，较高的通风温度和较高的面板表面温度有效地防止温暖的气流并获得更好的热舒适性。因此，
