Design and Analysis of Distributed Pump-System in District Heating Network

Abstract:

This paper presents a new scheme of distributed pump-system for district heating network. As no circulating pumps for the heat sources and no throttle valves for the users, much energy is saved. And the control of hydraulic parameters can be adjusted without interfering with that of the thermodynamic parameters. The novel scheme is available for both looped pipeline networks (LPNs) with multiple heat sources and dendritic pipeline networks (DPNs) with single heat source. Moreover, for users located at the hydraulic intersection points of the looped pipe network with multi-heat sources, their water temperature can be less affected by their own water consumption. A case study was presented and about 22% power saved when the new scheme was employed.
