Résumé

P?Tx (pressure-density-temperature-composition) properties for the HFO-1234yf + HFC-32 mixtures were measured by the isochoric method. Pressure vessel containing sample mixtures was connected to the pressure sensor directly in the silicon-oil bath. Pressure was measured by the digital quartz-pressure transducer and pressure indicator. Temperature was measured with the 25 O standard platinum resistance thermometer with an aid of AC thermometer bridge. P?Tx measurements were carried out in the temperature range from 310 to 395 K, and pressures up to 7 MPa along the five isochores. The pressure and temperature at the vapor-liquid equilibrium state were determined from the experimental isochore graphically.
