Information
This is a model of a simple rotary compressor that is used, for example, in close-loop systems like heat pumps or chillers. It inherits from PartialCompressor which inherits from PartialCompression. Therefore, please checkout these sub-models for further information of underlying modeling approaches and parameterisation:
- AixLib.Fluid.Movers.Compressors.BaseClasses.PartialCompressor.
- AixLib.Fluid.Movers.Compressors.BaseClasses.PartialCompression.
For this model, pressure and heat losses are assumed at inlet and outlet of the compressor. These pressure losses may occur due to reduction or enlargement of the cross-section and these heat losses may occure due to heat exchange with a fictitious wall that describes the shell of the compressor.
