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.

The following outlines the procedure for using REFPROP within any spreadsheet in Office 2007 or 2010: 1. Open REFPROP.xls and save it as an add-in, REFPROP.xla or REFPROP.xlam, in the main REFPROP folder, C:\Program Files\REFPROP. 2. Go to File/Options/Trust Center/Trust Center Settings (button at bottom right). 3. 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 not working matlab instruction in case of 4.2.6 wrapper is: I just downloaded the R513A.MIX file for REFPROP and placed it in the mixtures folder. The mixture can be used from within REFPROP itself without problems, but when i try to use it through CoolProp, from Matlab it fails: How can I fix running a code that requires air Learn more about matlab, refprop Welcome to REFPROP CAPE-OPEN.

I have built a Matlab program in version 2015a. The program is combined with Refprop interface. It runs perfectly when I use Matlab 2015a, but when I try to run my program with Matlab 2015b I get this error:

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 Matlab Refprop installed in my windows computer works well for pure working fluids.

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¶.

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.

The tables are stored in fluidTables as a structure array. For a mixture, it contains the names of the constituents in the mixture separated by semicolons or asterisks. Once the routine has been called with hFld set to the desired fluids, a space can be sent for all other calls that use the same fluid(s).

For a predefined mixture, the extension “.mix” must be included. 2019-06-12 I encountered a problem when calling Refprop software using Matlab.

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.

2021年3月15日 Moreover, zeotropic mixtures have been employed due to their lower irreversibility compared to single working fluid. Simulation code is developed in MATLAB software linked with the REFPROP software to extract the

Once the routine has been called with hFld set to the desired fluids, a space can be sent for all other calls that use the same fluid(s). For a predefined mixture, the extension “.mix” must be included. REFPROP is based on the most accurate pure ﬂuid and mixture models currently available.
