| description | Simple and effective calculation models to determine thermodynamic properties of refrigerant are very necessary for simulation of refrigeration system. Correlations of saturated vapor pressure and liquid density for HFC-32 refrigerant were presented. On basis of GMA state equation of liquid for HFC-32, Helmholtz bias function and Maxwell relationship of the thermal physical parameters, the calculation models of enthalpy, entropy and specific heat capacity were deduced. The calculation models mentioned above with no iteration can achieve high precision and stability. Comparisons between calculation models and REFPROP7 , covering saturation liquid line（275~335 ，0.862~4.095 ）, have been made. The results show that, the average relative error and maximum relative error for all calculation models are less than 0.776% and 4.464%, respectively. |
