The Journal of Engineering, Volume 2024, Issue 4, April 2024.A lumped‐element circuit model of district heating (DH) pipe considering heat loss, transfer delay and enthalpy transfer is proposed. The proposed model has a high level of accuracy and is computationally more efficient than the existing distributed‐element circuit model of pipe. The lumped‐element circuit representing the DH pipe has only two nodes by
