Network Design
Pipe dimensioning, loss calculation, network temperatures and heat density
Network design fixes pipe diameters, temperatures and route layout, and with them the investment costs and heat losses over the network's lifetime. The goal is a hydraulically capable network with low pressure and heat losses at an economic heat line density. This topic area covers pipe dimensioning, pressure-loss and heat-loss calculation, and the choice of network temperatures.
