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.
