Computationally efficient tabular interpolation · Highest accuracy psychrometric routines · User-friendly interface around the full capabilities of NIST REFPROP 

Hi Mr. Walter, I would like to thank for your reply in matlab homepage. I really appreciate that. I would like to confirm the following procedures and questions below to confirm whether there is a missing step or not: 1.

The later needs to be present in 1.Try to upload the Matlab and Refprop to latest version, I used 10.0 NIST and R2018b MTABLAB. The NIST REFPROP database provides the most accurate thermophysical property models for a variety of industrially important fluids and fluid mixtures, including accepted standards. It has proven to be an extremely useful tool used by industry, government, and academia, and it is a primary method for the dissemination of work done by the Thermophysical Properties of Fluids Group. 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. A liquid substructure contains the data for the Liquid Properties tab and a vapor substructure contains that for the Vapor Properties tab.

之前找了好久，尝试了几次，终于成功调用了。现在大多数使用的都是64位的matlab，现将64位调用方法给出： 1、将NIST REFPROP9.0将其安装在C:\Program Files\REFPROP（64位系统会强制安装在C:\Program Files（x86）\REFPROP里，只需将C:\Program Files（x86）里的REFPROP文件夹复制到C:\Program Files即可）。

NIST REFPROP contains 33 pure fluids and can calculate. Before using this function for the first time, you must download additional MATLAB ® support files from the website and save them in your REFPROP installation folder. Use the NIST search engine to find the files by name. The 32-bit MATLAB version requires one support file.

The NIST REFPROP program is designed to provide the most accurate thermophysical properties currently available for pure fluids and their mixtures. The present version is limited to vapor-liquid equilibrium (VLE) only and does not address liquid-liquid equilibrium (LLE), vapor-liquid-liquid equilibrium (VLLE) or other complex forms of phase equilibrium.
