How can I change the reference state in Modelica.Media.Water?
问题
Modelica.Media.Water中提供的水介质模型是基于273.15K和1bar的参考状态定义的。据我所知，似乎没有改变参考状态的方法，例如更改为298.15K和1bar。另一方面，对于气体模型，我们可以设置excludeEnthalpyOfFormation=false和referenceChoice=Modelica.Media.Interfaces.Choices.ReferenceEnthalpy.ZeroAt25C来进行更改。我不得不编辑Modelica.Media.Water的源代码来解决这个问题，但这是一个混乱的解决方案，应该有更好的解决方案。我认为Modelica.Media.Water介质模型也应该具有更改参考状态的可能性。有何想法？
英文:
Water media models given in Modelica.Media.Water are defined based on the reference at 273.15K and 1bar. As far as I can see there is no way of changing the reference state, for example, to 298.15K and 1bar. On the other hand this is possible for gas models; for gas media models we can set to excludeEnthalpyOfFormation=false and referenceChoice=Modelica.Media.Interfaces.Choices.ReferenceEnthalpy.ZeroAt25C. I had to edit the source code of Modelica.Media.Water to fix this issue and this is a messy solution, there are must be better solution. I think Modelica.Media.Water media models should also have the possibility of changing the reference state. Any thoughts?
