Condenser
Created Monday 04 August 2014
Stationary model of a condenser computing the values for outlet enthalpy and mass flow rate from given values for inlet enthalpy and mass flow rate and the prescribed condenser pressure at the inlet. The outlet pressure is calculated considering the filling level and the fluid density.
1. Purpose of Model
The model is supposed to be used for the simplified simulation of static cases. Its main purpose is to provide appropriate start or nominal values for similar dynamic model versions.
2. Level of Detail, Physical Effects Considered and Physical Insight
2.1 Level of Detail
Referring to Brunnemann et al. [1], this model refers to the level of detail L1 because the model only computes a set of parameters under specific conditions i.e. stationary.
2.2 Physical Effects Considered
- Condensation of fluid at constant pressure
- Gravimetric pressure considering filling level and fluid density
3. Limits of Validity
The model is only able to calculate stationary situations.
4. Interfaces
4.1 Steam Signals
For details see SteamSignal_blue, SteamSignal_red and SteamSignal_green.
Inlet: Blue connector
Outlet: Green connector
4.2 Medium Models
VLE medium model
5. Nomenclature
6. Governing Equations
6.1 General Model Equations
Energy
The specific outlet enthalpy is set to the bubble enthalpy considering the medium properties and condenser pressure
Mass
The mass balance is stationary with no change of mass.
Pressure
The inlet pressure is set to the condenser pressure.
The outlet pressure is computed taking into account the geodetic pressure of the containing fluid mass.

7. Remarks for Usage
The model can only be connected with components with matching connector colour (see Example of Usage in StaticCycles).
