制冷剂物性计算可视化的实现

Visualization of refrigerant physical properties computation

借助制冷剂物性数据图表计算制冷剂物性,繁琐、费时、误差大,为此本文给出了程序解决的方法,为制冷剂的热力计算及制冷循环分析提供的图形化计算工具。首先给出了制冷剂物性计算方程,作为程序计算的基础,然后简要介绍了VC++调用Fortran与Matlab混合编程的基本原理,最后以R22为例做了演示。采用的混合编程的方法,比较简单、快捷的实现了该功能,对解决其它类似问题有借鉴作用。

It is tedious, time-consuming, and error-large to compute physical properties with refrigerant physical properties data graph. A graphical tool for the thermodynamics computation and analysis of refrigeration cycle is supplied by program in this paper. Firstly, the refrigerant physical properties function are offered; secondly, the basic principle of calling Fortran and Matlab by VC ＋ ＋ is briefly introduced; fmally, the physical properties computation is visualized, and a demonstration is illustrated by R22 . The mixed programming method is relatively simple and fast to realize the function, and offers a reference for similar problems.
