摘　　要：本文分析了空气载能辐射空调系统末端的传热特性,并运用热阻分析法建立了辐射孔板的平均温度以及夏季最低温度和冬季最高温度的集总参数模型,通过CFD模拟与实验对该模型进行验证,并基于该模型分析辐射孔板表面温度的均匀性。结果表明,本文提出的模型准确性较高,且空气载能辐射孔板与传统的金属辐射板相比,表面温度分布较均匀,供冷/热效果更好。The heat transfer property for the terminal of the air carry energy radiant air conditioning system is explored in this paper, and three lumped-parameter models based on thermal resistance analysis for the average temperature of radiant orifice plate, lowest temperature under summer condition and highest temperature under winter condition are established, which are verified by CFD simulation and experiments. Moreover, the temperature distribution uniformity of radiant orifice plate is analyzed based on the proposed models. Results show that the accuracy of proposed lumped-parameter models are relatively high. And the temperature distribution uniformity is better compared to traditional metal radiant plate, which leads to preferable cooling or heating effect.
