分布式水泵系统保持临界零压差状态的调节

Critical zero pressure difference state control in distributed pump systems

分布式水泵系统采用小流量大温差运行,且在全年供暖期内保持临界零压差运行,是一种节能方案。以保持临界零压差运行状态为目标,提出了变流量分布式水泵系统的自动调节系统,介绍了全供暖季的调节策略及实例分析。

States that it is an energy efficient mode to adopt variable flow operation with large temperature difference and small water rate and the zero pressure difference point control throughout heating period.Aiming at keeping critical zero pressure difference state operating,proposes the structure of the automatic control system and regulation strategy in the whole heating season,and demonstrates a case study.
