摘　　要：利用[火用]分析的方法，对辐射末端和普通风机盘管的[火用]效率进行比较，分析了辐射末端的节能率。结果表明设计工况下辐射末端[火用]效率为普通风机盘管的1．6～1．9倍，相对[火用]效率随着参考温度的升高而降低，随着辐射末端承担显热负荷比例的增加而增加。从能和质的节约角度出发，应尽量提高辐射末端承担的冷负荷比例。Using the method of exergy analysis, the exergy efficiency comparison between the radiant terminal device and the ordinary fan-coil is given, and the energy-saving potential of the radiant terminal device is analyzed. The results show that the exergy efficiency of the radiant terminal device is 1.6 - 1.9 times of the ordinary fan-coil. Ralative exergy efficiency reduces with the reference temperature rises, and increases with the sharing rate of sensible heat load of radiant terminal device increases. From the view of the saving of energy and quality, the sharing rate of sensible heat load of radiant terminal device should increase.
