摘　　要：利用Fluent软件对贴附射流与辐射板复合空调系统进行模拟计算,分析其舒适性,并根据壁面温度计算其辐射不对称性。结合模型设置和模拟结果提出3种改善其辐射不对称性的方案并进行模拟计算。结果表明,侧壁辐射板布置于正对送风口方向以及与送风口所在壁面相邻壁面的下部空间,辐射不对称性可降低1.5~2.0℃,且不会有结露的风险,温度均匀性优于原方案。The composite air-conditioning system with wall-attached jet and radiant panel is simulated using Fluent software,so as to analyze the comfort and calculate the radiant asymmetry according to the wall temperature.Three improvement schemes for radiant asymmetry based on the model settings and simulated results,are proposed and simulated.The results reveal that the radiant asymmetry can be decreased by 1.5-2.0℃ when the side radiant panel locates in the opposite wall of air inlet or in the lower half adjacent wall of air inlet.Furthermore,there is no dew condensation risk,and the temperature uniform behaves better than that of the original scheme.
