packageSpecifiedEfficiencies
Package that engine efficiencies that are specifiied
Extends from Modelica.Icons.VariantsPackage (Icon for package containing variants).
Information
This package contains volumetrtic efficiencies that are already specified. This means that the calculation approaches of the volumetrtic efficiency presented before are adapted for a specific compressor type and a specific refrigerant.
Naming and abbreviations
In the following, a guideline of naming efficiency models is summarised:
Approach of calculating efficiency _ Valid refrigerants _ Displacement volume _ Type of compressor
Moreover, the modeles are saved in a specific order. First, generic models are saved and then models based on the similitude theory are saved. Last, models of specific compressors are saved.
