FRIG module
Knowledge of the properties of refrigerants is required in many industrial engineering processes, e. g. for air conditioning and cryogenic applications.
The FRIG program generates the properties of refrigerants for a given pressure and temperature.

R 404 a This mixture of R125, R134a and R143a has a very narrow boiling range (< 1 K). Therefore it is assumed as being azeotropic.[1] Reid R. C., Prausnitz J. M., Poling B. E. "The Properties of Gases & Liquids", McGraw Hill, 4th edition 1987
