Collection of models that validate the compressor models
Information
This package contains validation models for the classes in
Buildings.Fluid.HeatPumps.Compressors.
Note that most validation models contain simple input data
which may not be realistic, but for which the correct
output can be obtained through an analytic solution.
The examples plot various outputs, which have been verified against these
solutions. These model outputs are stored as reference data and
used for continuous validation whenever models in the library change.
