.IBPSA.Fluid.HeatPumps.Compressors.BaseClasses.PartialCompressor

Information

This is the base class for the compressor model.

The model evaluates the evaporating pressure of the refrigerant p_eva, the specific enthalpy of the evaporating saturated refrigerant vapor h_eva, the condensing pressure of the refrigerant p_con and the specific enthalpy of the condensing saturated liquid refrigerant h_cond at the evaporating temperature T_eva = port_a.T and condensing temperature T_con = port_b.T.

Thermodynamic properties are evaluated from functions contained in the specified refrigerant package.

Assumptions and limitations

The model assumes isothermal condensation and evaporation, therefore refrigerant mass flow is not accounted for and heat ports are used instead of fluid ports.

• May 30, 2017, by Filip Jorissen:
  Removed pressure_error as this is replaced by IBPSA.Fluid.HeatPumps.Compressors.BaseClasses.TemperatureProtection. See #769.
• May 26, 2017, by Michael Wetter and Thierry Nouidui:
  Reformulated isOn to use the same construct as the hysteresis block, and to work around a JModelica limitation.
  This is for #774.
• April 25, 2017, by Michael Wetter:
  Reformulated when conditions and moved common assignments to this base class.
  This is for #739.
• November 11, 2016, by Massimo Cimmino:
  First implementation of this base class.
