我尝试通过 python 访问 NIST refprop 数据库。为此，我从http://www.boulder.nist.gov/div838/theory/refprop/Frequently_asked_questions.htm下载了 refprop python 模块

尝试导入模块时，我收到以下错误：

>>> import REFPROP
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "C:\Python33\lib\REFPROP.py", line 6525, in <module>
   setpath()
File "C:\Python33\lib\REFPROP.py", line 381, in setpath
   _setpath(path)
File "C:\Python33\lib\REFPROP.py", line 421, in _setpath
   _rp.SETPATHdll(ctypes.byref(_hpth), ctypes.c_long(255))
File "C:\Python33\lib\ctypes\__init__.py", line 366, in __getattr__
   func = self.__getitem__(name)
File "C:\Python33\lib\ctypes\__init__.py", line 371, in __getitem__
   func = self._FuncPtr((name_or_ordinal, self))
AttributeError: function 'SETPATHdll' not found 
>>>

我发现这个 SETPATHdll 函数不包含在 refprop.dll 文件中。尽管如此，模块是为这个文件编写的。有人可以帮忙吗？谢谢你 。

将 CoolProp 与 REFPROP 包装器一起使用：

安装： https ://pypi.python.org/pypi/CoolProp/4.2.5

示例： http ://coolprop.sourceforge.net/FluidInformation.html#refprop-fluids-and-mixtures
