.TransiEnt.Consumer.Heat.ThermalHeatConsumer

Information

1. Purpose of model

Model of a thermal heat consumer supplied by hot water that controls the water mass flow in order to hold the consumer temperature steady.

2. Level of detail, physical effects considered, and physical insight

1. The model consists of a thermal capacity whose temperature is the target value.
2. The incoming heat flow is dependent on the parameter kc_nom (heat transfer coefficient of radiator).
3. The loss heat flow / heat demand is calculated by conduction loss to the ambient defined by the thermal conducticity (G) and the ambient temperature defined by a modelica table.
4. The target temperature is controlled with a PI Controller by changing the valve opening, parameterized by delta_p_nom, rho_nom and m_flow_nom (and the pressure loss model)

3. Limits of validity

- No heat loss due to radiation

- No heat transfer inside consumer, transfered heat is directly connected to the consumer capacity

- Lumped Capacity

4. Interfaces

- FluidPortIn and FluidPort out for heating water flow
