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.
