FRIG module
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
(-) i-Pentane
