Primary/Secondary Pumping[LINK]
As mentioned in sections Primary Cooling System Supply Side Loop Construction and Secondary Chilled Water Loop Supply Side Loop Construction, the CW primary Circ Pump and the CW Sec Circ Pump function as the primary/secondary (respectively) pumping system. The primary pump is a constant speed pump that circulates chilled water at a constant flow rate through one side the plate heat exchanger in the primary chilled water loop. The secondary pump is a variable speed pump that circulates chilled water at a variable flow rate through the other side of the plate heat exchanger depending on the demand load.
