Thermodynamic properties of HFC-32 (difluoromethane).
Author(s) : PIAO C. C., NOGUCHI M.
Type of article: Article, IJR article
Summary
An 18-coefficient modified Benedict-Webb-Rubin equation of state of HFC-32 (difluoromethane) has been developed, based on the updated available PVT measurements, heat capacity measurements and speed of sound measurements. Correlations of vapour pressure and saturated liquid density are also presented. This equation of state is effective both in the superheated gaseous phase and compressed liquid phase at pressures up to 70 MPa, densities to 1450 kg/m3, and temperatures from 150 to 475 K, respectively.
