摘要

The current status of a new fundamental equation of state for trans-1-chloro-3,3,3-trifluoro-1-propene [R-1233zd(E)] is given. Due to its non-flammability and preferable thermophysical properties,this refrigerant is considered as one possible alternative for 1,1,1,3,3-pentafluoropropane (R-245fa). The new equation is valid for temperatures from 215 K to 444 K and pressures up to 35MPa. Expected uncertainties in calculated properties in this range are 0.01 % in liquid densities,0.03 % in vapor densities, 0.05 % in vapor pressures, and 0.1 % in vapor- and liquid-phase soundspeeds. Improvements from the currently available equation are that the upper limit of pressureis extended to 35 MPa and that liquid-phase sound speeds are represented more accurately. Theequation shows quite reasonable extrapolation behavior at extremely low and high temperatures,and at high pressures. The ISO/TC86/SC8 committee will recommend the final form of this equationas an international standard formulation for R-1233zd(E).
