When compiling a model in WinDali the following problems can occur:

Problem	Solution
Problems compiling a model and	When you open a model be sure to use File|Open Model.
thereafter running it	Models are always saved as projects (not in single files).

Problem compiling a model (can’t create model file)

Remember to close the Simulation program before compiling the model currently loaded in the Simulation program. If you always run the Simulation program from the Model Editor this problem should not occur…

8 Using refrigerant equations

With WinDali comes a package with equations for the thermodynamic and thermophysical properties of 45 refrigerants. These equations can be directly used in your models.

To include one of the refrigerants do the following:

1.Include CRefrigWrapper in your uses clause

2.Create a TRefrigerantWrapper object

3.Use the equations

4.Free the object.

All these things will automatically be included if you select File|New|New Refrigeration Model when you create your model.

You can inspect CRefrigWrapper.pp in the \lib directory to see which functions you can call with a TRefrigerantWrapper object, browse the documentation installed with WinDali, or just use the Procedures tab in the Model Manager in Model Editor.
