Knowledge of the properties of refrigerants is required in numerous process engineering processes, e.g. in air conditioning and refrigeration technology.
The FRIG program calculates the physical properties of refrigerants as a function of pressure and temperature, both in the single-phase area and at the phase boundary.
The following refrigerants are available:
R 22 – Chlorodifluoromethane
R 23 – Trifluoromethane
R 32 – Difluoromethane
R 134A – 1,2,2,2,-Tetrafluoroethane
R 142B – 1-chloro-1,1-difluoroethane
R 152A – 1,1-Difluoroethane
R 290 – Propane
R 404A – Near-azeotropic mixture of R 125, R 134A and R 143A
Mixture of R 125, R 134A and R 143A. The mixture has a very narrow boiling range (< 1 K) and is therefore assumed to be azeotropic.
R 410A – Near-azeotropic mixture of R 32 and R 125
Mixture of R 32 and R 152. The mixture has a very narrow boiling range (< 0,2 K) and is therefore assumed to be azeotropic.
R 507 – azeotropic mixture of R 125 and R 143A
R 600 – n-Butane
R 600A – i-Butane
