Application Description
Secondary pumps in a primary/secondary chilled water pumping system are used to distribute the chilled water from the primary production loop to the loads. A primary/secondary pumping system allows constant flow to be maintained in the primary loop, while meeting the variable flow requirements of the secondary loop. Because the flow is variable in the secondary loop, the minimum effective pressure difference can be maintained to reduce system noise and improve efficiency. The secondary (distribution) pumping loop is described as "de-couple" from the primary (production) pumping loop.More....
