摘　　要：在Martin-Hou方程的基础上,提出了R410a制冷剂在饱和线的热力学性能参数和传输特性参数的显式快速计算模型.该模型不存在迭代,在保证较高计算精度的同时,可以保证模型的计算速度和稳定性.以热力学性能参数计算软件REFPROP 7的数据源作为原始数据,在饱和线（139.00~343.32 K）范围内,对R410a制冷剂的性能参数进行拟合,并将该模型的计算结果与REFPROP 7数据源进行对比.结果表明：所有快速计算模型的总平均误差均小于1.174%,最大误差小于13.218%;其计算速度比REFPROP 7提高了2~4个数量级.Based on the Martin-Hou equation of state,a fast calculation model for R410a thermodynamic and transport properties,covering saturation curve（139.00—343.32 K）,was presented due to no need of iteration.This method can not only achieve the accuracy,but guarantee the calculation stability and high calculation speed of thermophysical and transport properties of R410a.The source data was calculated from REFPROP 7.The total mean relative error and maximum relative error for all fast calculation models are less than 1.174% and 13.218%,respectively.The comparison result shows that the calculation speed of the fast calculation model is two to four orders faster than those of REFPROP 7.
