Abstract:
The last mile for any project is always the most difficult and expensive. This certainly holds true for designing and building commercial buildings and their mechanical systems. For a chilled water system the last mile is balancing. Grundfos Distributed Pumping is the next generation of chilled water system design: Variable Primary / Distributed Secondary. This revolutionary, yet simple system design consists of a chiller and pumps in a variable primary configuration, connected to a distributed secondary via a 4-temperature bypass. Intelligent pumps are installed at each load in the system and not only provide precise flow and pressure directly to each load, they are auto-balanced upon installation and throughout the chilled water system’s life cycle. Simplifying installation, maximizing occupant comfort, saving pump energy and significantly impacting the chiller plant’s Delta T.
Learning Objectives:
● Evaluate the evolution of chilled water piping layouts
● Define a distributed Pumping concept
● Recognize designing and sizing a distributed pumping system
● Develop a pressure profile of comparison to a conventional system
Grundfos is one of the world’s leading water technology companies. We are committed to pioneering solutions to the world’s water and climate challenges and improving the quality of life for people.
