Information

This components, refleting the first principe of thermodynamic (energy conservation), computes the variation of the temperature (the potential variable) from a heat flow balance and its thermal inertia.

The basic constitutive equation for convection is :

Where :

• port.Q_flow: The Heat flow balance at the heat port
• m: The Mass of the inertial component
• cp: The specific heat capacity at constant pressure

If energyDynamics parameter is SteadyStateInitial, the modelica solver will determine which value of the temperature ,at the initilisation, that satisfies a zero time derivative and will ignore the Tstart parameter.

If energyDynamics parameter is FixedInitial, the initial temperature is equal to the value of the T_start parameter.

If energyDynamics parameter is SteadyState, the heat capacitor becomes non inertial and behaves like a temperature sensor. The heat flow through the port port.Q_flow is set to 0.
