What is Primary and Secondary Pump? Explained | Animation |

Primary Pumps
Location: Directly connected to the chillers themselves.
Purpose: Circulate chilled water through the chiller's evaporator, where heat from the building is absorbed, and then back to the chillers.
Flow Rate: Often designed with a constant flow rate to ensure the chillers operate at their optimal efficiency.
Types: Can be dedicated (one pump per chiller) or headered (multiple pumps serving multiple chillers).
Secondary Pumps
Location: Part of the separate chilled water distribution loop to the building.
Purpose: Distribute the chilled water from the primary loop out to the various air handling units, fan coil units, or other cooling equipment throughout the building.
Flow Rate: Designed with variable speed drives (VFDs) to precisely adjust flow as cooling demand in the building changes.
Control: Operate based on a differential pressure setpoint within the distribution loop, ensuring that there's a consistent supply of chilled water at the needed locations.

00:02 Two types of pumps used in chiller plant: primary and secondary
00:29 Primary chilled water system uses only a primary pump.
01:10 Primary pump in HVAC system circulates chilled water from chiller to AHU.
01:45 Primary chilled water system less efficient than primary secondary system
02:16 Primary secondary chilled water system uses two pumps
02:49 Primary pump sends water to chiller for consistent flow
03:22 Primary and secondary pumps prevent water mixing in HVAC systems.
