Unified fundamental equation of state for R1234yf has been developed that satisfies the scaling critical point theory. It has been demonstrated that the proposed equation of state truly represents the peculiarities of the thermodynamic surface from the qualitative and quantitative point of view: first, in the regular part of the thermodynamic surface, secondly, in the region of strongly developed density fluctuations. The operating range of the equation of state has been determined on the basis of the benchmarking analysis with experimental and estimated data: for temperature 230 ≤ T ≤ 420 K; for pressure 0.001 < p < 20 MPa.
