WebbThe working condition with high heat loss was selected to simulate aged pipes (Table 6). Fig. 15 shows the heat loss of the repaired pipe with different liner thicknesses and thermal conductivities. Within the parameter range, using CIPP liner only reduced the heat loss by 9.1% at δ l = 5 mm and k l = 0.2 W m −1 K −1 . Webb15 mars 2024 · A common way to reduce heat losses is by reducing the network operating temperature, as proposed by Pirouti et al. [ 8 ]. In their work, optimisation has been performed by adjusting the flowrate and supply temperature of the heat carrier to achieve minimisation of the overall energy losses and DHS cost.
