Summary

An equation of state for a non-ozone-depleting mixture and nature refrigerants R125/R290 is developed by the linear combination of free Helmholtz energies of the mixture's components with adding of interacting function of the components. Coefficients of equation are determined on the basis of experimental and calculated data on the mixture's density, taking into account the requirement of phase equilibrium. The equation describes the thermodynamic properties of vapour at temperatures from 253 to 423 K and at pressures up to 6.7 MPa and properties of saturated vapour and liquid.
