Primary vs secondary controls
WebUsing the COSO Framework - Weaver WebJul 22, 2024 · The primary circuit has low head primary pumps which typically maintain a constant flow rate through chillers. The secondary circuit has high head secondary pumps which maintain flow through loads (AHUs, FCUs, etc). Secondary pumps are usually fitted with VFDs so that they may vary flow through the secondary circuit as per load conditions.
