The Compressor_EN12900 model represents the compression of a fluid in a scroll compressor according to standard EN12900. It is a lumped model. It is characterized by two flow connector for the fluid inlet and outlet and by a mechanical connector for the connection with the electric driver.
The assumptions for this model are:
- No dynamics ( it is considered negligible when compared to the one characterizing the heat exchanger).
- No thermal energy losses to the environment
- Mass flow and consumed power are calculated with a polynoms as a function of the saturation temperature of the corresponding inlet and outlet temperature
In the General tab the following option is availabe:
- CPmodel: it allows to select one of the different available scroll compressor characteristics.
In the EN12900 standard, the compressor consumption and the mass flow rate are expressed as a function of the evaporation and condensation temperatures with the following equations:
