Welcome to REFPROP CAPE-OPEN. Welcome to REFPROP CAPE-OPEN. This program provides a CAPE-OPEN versions 1.0 and 1.1 interface to NIST's REFPROP application. For this program to work, a separate installation of NIST's REFPROP version 8 or later must be present on your system. For more information about REFPROP, see the NIST web site. What CAPE-OPEN?

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. Mixture calculations 2014-12-11 The substance can be a pure fluid such as R-134a or a predefined mixture such as R-404a, a ternary mixture of R-125, R-143a, and R-134a. 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. 2019-02-24 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. Mixture calculations 2017-08-04 For a mixture, it contains the names of the constituents in the mixture separated by semicolons or asterisks.

Mixture calculations You need few files. which you can download from Refprop files -Link : https://trc.nist.gov/refprop/LINKING/Linking.htm#MatLabApplications.Refprop Google driv t5 = 6+273; %in kelvin. p5 = refpropm ('P','T',t5,'Q',1,'r407c.mix'); h5 = refpropm ('H','T',t5,'P',p5,'r407c.mix'); s5 = refpropm ('S','T',t5,'P',p5,'r407c.mix'); but i got some error, said that; Error using refpropm (line 267) [SETUP error 101] error in opening file for component #-22; filename = (C:\Program Files.

matlab -r MATLABBuilder.m. So I downloaded coolprop-code from https://github.com/ibell/coolprop and compile the matlab wrapper present on that distribution. By doing that, I did compile the old 4.2.6 coolprop version. I understand that mixture syntax is not available in such an old version. The not working matlab instruction in case of 4.2.6 wrapper is:

REFPROP, and therefore the REFPROPFlowStation, runs fast if the composition is set to a pure fluid or a pseudo-pure fluid. However, execution speed slows when composition comprises multiple fluids, whether set via a predefined mixture file (".mix" extension) or defined manually via the FlowStation comp attribute. how to use refprop with mixtures.

All the pure fluids in REFPROP are used just like the CoolProp fluids except that “REFPROP-” is added at the beginning of the fluid name.

The initial versions of REFPROP provided (sometimes preliminary) data to allow screening studies of possible replacements for the CFC and HCFC refrigerants. As more and better data on the “new” refrigerants have become available, we have continually updated the program to implement the most accurate pure fluid and mixture models available.
