Did you know that switching from a valve-based system to distributed pumps can save energy significantly?
Most chilled water systems use large centralised pumps and chillers controlled by valves. These valves waste loads of energy and make it difficult and time-consuming to balance the system correctly. Distributed Pumping systems for commercial buildings is a paradigm shift towards decentralised pumps that can save energy significantly and create a more consistent, comfortable climate throughout the building.
54% energy savings
Grundfos Distributed Pumping helped Ngee Ann, a large university building in Singapore, increase Delta T by 28% and reduce total pump energy by 54% – all while providing optimal comfort for building users.

How decentralised pumping saves energy
Distributed Pumping solutions replace centralised pumps and energy-consuming balancing and control valves with intelligent pumps placed on each floor of the building. This means the new system is equipped with components that generate pressure only when and where needed. The result is substantial energy savings and a more comfortable indoor climate.
How to increase comfort and improve Delta T
Inadequate commissioning leads to poorly balanced systems and excessive energy use. Replacing valves with pumps ensures optimal pressure and flow to each terminal unit at all times. So, you can increase comfort and improve Delta T. Get a great introduction to how Grundfos Distributed Pumping works in this video.

Distributed pumping in practice
Distributed pumping can be applied to existing chilled water systems that need retrofitting or to new commercial buildings planned with chilled water air conditioning. It can also be applied in decentralised chilled water systems. Dig into the technical details of these specific applications and more in our distributed pumping white paper.

采用分布式水泵节省作业成本

分布式泵送解决方案是否需要液压平衡？
不需要。 因为我们使用小型循环泵作为盘管泵，向每个终端单元（即 空气处理机组），您整栋建筑将在任何负荷下达到完美的平衡。
这也简化了设计阶段，因为在进行HVAC设计时不再需要确定关键压力点/索引回路。 有了Distributed Pumping，您的整个系统将解耦，而且每台泵的大小都必须能够提供合适的流量。
相比传统的带阀门系统，资本投入如何？
由于格兰富分布式泵系统正在用盘管泵代替阀门，并降低了初级泵的kW功率，因此其资本投入将与传统系统相同，或者大约高出20％，具体取决于传统阀门的选择设计。
由于不需要水力平衡或无需对设定点进行设定，分布式泵系统调试工作大幅减少（例如： 恒定旁路压差设定值）
藉由节能，且易于试运转的分布式泵系统解决方案，将投资回本时间维持在6个月以下。
相比传统系统，分布式泵系统的要求如何？
自1959年以来，罐头转子型循环泵一直由格兰富生产，1991年推出集成速度驱动器，因此该设计非常可靠且经过良好测试。 当前版本的MAGNA3于2012年问世，全球混合应用的销量超过100万台。
MAGNA3泵的预期寿命为10年，但该泵的使用寿命可以更长，并能满足任何类型控制阀的需求。 此外，若连接至楼宇管理系统（BMS），系统将能够侦测任何泵浦的警告或警报，确保设施管理人员可根据需要作出回应。
