Information

Purpose of model

A model of a district heating network consumer. It contains a P-Controller, a pump, a heat exchanger, a thermal capacity and a heat conductance. The P-Controller sets the mass flow rate through the pump so that the temperature of the thermal capacity is kept constant. The thermal capacity represents the thermal capacity of the building. Heat losses are calculated with the thermal resistance and the temperature difference between the thermal capacity and the ambient temperature. The ambient temperature is set with a RealInput.

The difference to the consumer and Consumer_SLP model is that the supply and the return temperature of the building are calculated from the heat caracteristics of the building.

Level of detail, physical effects considered, and physical insight

• P-controler
• heat losses from the building to the environemnt
• a thermal capacity of the buildings
