# Dynamic condenser  

In the condenser, the cooling water flows inside the tube bundle, while the steam and condensate flow inside the cavity.  
This model completes the [simple dynamic condenser](modelica://ThermoSysPro.WaterSteam.HeatExchangers.SimpleDynamicCondenser) for it features the thermal exchanges between the fluid in the cavity and the cooling fluid flowing through the tube bundle.  


## Modelica component model  

The equations mentioned below are implemented in the component *DynamicCondenser*, located in the *WaterSteam.HeatExchangers* sub-library.  
This component has 6 connectors:  
- C1vap: high-pressure vapor inlet,  
- C2vap: low-pressure vapor inlet,  
- C1: extra water inlet,  
- Ce1: cooling water inlet,  
- Ce2: cooling water outlet,  
- C2ex: condensed water extraction outlet.  

The component is an assembly of a [(monophasic) tube bundle](modelica://ThermoSysPro.WaterSteam.HeatExchangers.DynamicTwoPhaseFlowPipe), a [heat exchanger wall](modelica://ThermoSysPro.Thermal.HeatTransfer.HeatExchangerWall), and a [two-phase cavity](modelica://ThermoSysPro.WaterSteam.Volumes.TwoPhaseCavity) sub-components.
