摘要： 在Martin-Hou方程的基础上，提出了R410a制冷剂在过热区（压力4~4 355 kPa，过热度0~100 K）的热力学性能参数和传输特性参数的计算模型，以REFPROP 7的数据源作为原始数据，在过热区范围内对R410a制冷剂的热力学性能参数进行拟合，并将该模型的计算结果与REFPROP 7数据源进行对比.结果表明，所提出的显式计算模型的平均误差小于1.24%，最大误差小于14.30%，计算速度比REFPROP 7提高了2~4个数量级.

Abstract: Based on the Martin-Hou equation of state, a fast calculation model for R410a thermodynamic and transport properties, covering superheat region(pressure:4—4 355 kPa, superheating of 0—100 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, and it is also convenient in cases of simulation of refrigeration system. 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 1.24% and 14.30%, 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.
