A new equation of state (EOS) for 1,1-difluoroethane (R152a) is developed in the form of the Helmholtz free energy. The EOS is valid for temperatures between 213 and 433 K (0β’55(ΒΉ P (1β’12) and pressures up to 20 MPa (P P (4β’4). It covers the compressed liquid, gas and two-phase regions. R152a, which
