%X 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.
