Thermal transients arise due to the propagation of heat fronts within the pipe network. These are caused by heat plant start-ups and shutdowns or a change in the thermal load or the supply temperature. Management of this phenomenon is important for the reliable supply of adequate heat amounts to consumers in an energy efficient manner.

Optimizing pipe network design and central plant positioning of district heating …

A sub-optimal pipe network layout would lead to a longer total system pipe length and a larger pipe diameter, which causes a higher capital investment and a higher system pressure drop. Similarly, a sub-optimal central plant positioning will also increase the total pipe network length, capital investment, and operational energy use.

Heat Distribution Network

Typical heat loss in whole networks is 5–10% of heat generated in plants, but up to 20–30% can occur in areas with low linear heat densities. Also, the distribution cost depends on the linear heat density. The cost is low beyond 20–30 GJ/m but increases very quickly below 6–8 GJ/m.
