Essay

The dissertation is dedicated to the development of reliable unified equations of state (UES) for refrigerants R32 and R125 and to the calculation of tables of thermodynamic properties of these substances for a wide range of parameters. The equations were compiled by means of the step-wise regression method, to which improvements have been added. They allow obtaining equations of high quality with moderate quantity of terms. The wide-spread forms of EUS were investigated. It is shown that the use of exponential terms significantly increases the accuracy of equations. The obtained equations of state and tables have been introduced in the industry, scientific and educational establishments.
