Select the mixture constituents from the list on the left by clicking on the fluid name, and then on the Add button (or simply double click). That fluid then moves from the list on the left to the list on the right. The fluids in the right list become part of the selected fluid system. To remove a fluid from the right list, click on the fluid name and then click the Remove button (or simply double click).
REFPROP is based on the most accurate pure fluid and mixture models currently available. It implements three models for the thermodynamic properties of pure fluids: equations of state explicit in Helmholtz energy, the modified Benedict-Webb-Rubin equation of state, and an extended corresponding states (ECS) model.

From Matlab command line you can call the methods in Prode Properties by typing the names, for example to calculate cp/cv at specified conditions >> EstrGCp(1,300,500000)/EstrGCv(1,300,500000) >> ans = 1.3211 or, to calculate the speed of sound for vapor phase at same conditions >> EstrGSS(1,300,500000) >> ans = 374.1625 It contains a limited number of pure fluids (water, CO2, R134a, nitrogen, oxygen, methane, propane, helium, hydrogen, and dodecane), along with air as a pseudo-pure fluid. It also allows mixture calculations of a 50/50 molar mix of nitrogen and methane or of a 79/21 molar mix of nitrogen and oxygen for teaching vapor-liquid equilibrium (VLE). The ammonia-water mixture flowing into the absorber is assumed to be a mixture of the dilute solution flowing out of the absorber (saturated liquid, x sol = 0.3, P sol = 500 kPa, and m ˙ sol = 3 g s-1) and refrigerant vapor from the evaporator (saturated vapor, y ref = 0.999, P ref = 500 kPa, refrigerant flow rates vary with time in the simulation, so m ˙ ref ≈ 1 g s-1). As the two-phase ammonia-water mixture flowing through the absorber has substantial variations in density, the exact 1 C3H8Tables = twoPhaseFluidTables([-195,800],[0.00001,10],50,50,150, 'R401A', 'C:\Program Files (x86)\REFPROP') fails to find the mixture file R401A.MIX There is a file int eh REFPROP/MIXTURE folder labled R401A.MIX 2019-03-22 Define New Mixture¶.

For example, defining a mixture of R32, R125, R134a, and Propane is quickest by typing the following sequence: ‘r3.r125.r134.pr.’ If a wrong letter or number is entered, use the backspace, thus if ‘r124’ is entered in this example, press the backspace and then a ‘5’, and the program will jump to R125.

The database can be REFPROP, an industry standard developed by NIST, or the open-source CoolProp. The tables are stored in fluidTables as a structure array. t5 = 6+273; %in kelvin.

m using Matlab, set path to refprop directory and tried the load library command REFPROP Mini pode ser instalado nas versões 32-bit do Windows XP/Vista/7/8/ 10.
3. REFPROP needs to be able to find the fluid and mixture files at runtime, at a location specified on your computer. CoolProp allows you to avoid the pains of decoding REFPROP’s internal logic for finding these files by explicitly specifying the path that it should tell REFPROP to look for the fluid files.
