Energy Conservation Analysis of Single-Pipe and Multi-heat Sources with Multi-pumps of Direct Connected System in Central Heating

This paper respectively calculates a actual project, using the traditional design method(single pump single heat source indirectly connected branched system) and the novel design method (single-pipe multi-heat sources with mixing-pumps of direct connected system), gets a series of important data of hydraulic working condition, then demonstrates the superiority of the new heating system in the aspects of reducing system pressure and reducing the invalid electricity consumption by the methods of contrast and analysis.
