| Abstract: | The research work on thermophysical properties of difluoromethane (HFC-32) is summarized. Experimental data of critical parameters, vapor pressure, PVT, speed of sound, ideal-gas heat capacity, surface tension, viscosity, thermal conductivity are given and corresponding correlations are developed. The cross equation of state, the correlations of saturated liquid density and second virial coefficient for HFC-32 are also developed. |
