Abstract
The set of equations of state, that allow to obtain the refrigerant thermodynamic parameters by known temperature and pressure, are discussed. The technique of obtaining the coefficients of the equations based on reference data. Data on refrigerant R134a are used as an example. A computer algebra system Mathcad used to solve this problem.
