Information

1. Purpose of model

This model illustrates possible applications of the library to model district heating grids. It shows a heat producing unit and the supply and return lines for distribution. The pump located at the heat production site is controlled based on pressure values as well as on mass-flow values. The pumps at the return line are pressure controlled.

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

The model uses mainly components with level of detail of L2 and L4.
