# **Variable Primary versus Primary/Variable Secondary Chilled Water Pumping**

  

What You Will Learn  
Within the broader context of design decisions, the choice between Variable primary flow and Primary/Variable secondary seems almost inconsequential. But the differences in operating practices and efficiencies between the two types of systems matter. Those aspects, combined with the short and long-term cost implications, make this an important design choice for any building. For a careful comparison, plus the latest info on the merits of each configuration, and an explanation of industry-leading variable speed technology.
