Nist refprop program license#
REFPROP CAPE-OPEN requires a separate installation and license of REFPROP. The REFPROP CAPE-OPEN application has been written by Jasper van Baten, AmsterCHEM (C) 2021. Of the CAPE-OPEN standard is advised if supported by the hosting simulation application. Performance, a wider definition of properties, availability of two-phase composition derivatives and more flash types, use of version 1.1 It is therefore compatible with newerĪpplications that implement the version 1.1 standard, as well as with older applications that implement the version 1.0 standard. REFPROP CAPE-OPEN implements the CAPE-OPEN versions 1.0 and 1.1 thermodynamic standard implementation. One could for example use CAPE-OPEN to import thermodynamic calculations into Matlab (see Matlab CAPE-OPEN Thermo Import). Such programs can be flowsheet simulation applications (for example COCO), or any other type of application that requires thermodynamic and physical property calculations or thermodynamic phase equilibrium calculations.
Nist refprop program software#
The CAPE-OPEN standards are freely available from the CAPE-OPEN Laboratory Networks.ĬAPE-OPEN defines standards for interaction of many types of process engineering software components this implementation uses the Thermodynamic and Physical Property standard description versions 1.0 and 1.1 to allow CAPE-OPEN compliant applications to use REFPROP for their thermodynamic calculations. CAPE is an acronym for Computer Aided Process Engineering.
For more information about REFPROP, see the NIST web site.ĬAPE-OPEN is an open standard for interoperability of chemical process engineering applications.
For this program to work, a separate installation of NIST's REFPROP version 8 or later must be present on your system. This program provides a CAPE-OPEN versions 1.0 and 1.1 interface to NIST's REFPROP application. Certainly I can get labview to call in properties for a single fluid very easily, but I can't work it for a mixture.Welcome to REFPROP CAPE-OPEN. If I could just get these calls right, I think everything else would be OK. I also don't know where you specify which mixture (the name, eg. However, the control is a string control, not an array, so I can't figure out how you enter in several fluid names, to make up a mixture. In the DLL descriptions that come with Refprop (for theSETUP subroutine) it names one of the inputs as "hfiles" and refers to this as an "array of file names specifying fluid/mixture components for each of the nc components". When I try to enter a mixture name into this string control, nothing is returned. The "refrigerant file" input in your VI is a single string which can take a single refrigerant (pure fluid) name.
Nist refprop program how to#
However, I still seem to have the same problem, namely how to get properties of a mixture back from the Refprop DLL.
