How to Reduce Chilled Water Pump Energy Costs
Discover how differential pressure control and VSD tuning can cut chilled water pump power use by up to 30% in Australian HVAC plants.
Chilled water systems are among the biggest consumers of electricity in large facilities.
By fine-tuning differential pressure (DP) setpoints and verifying sensor calibration, operators can ensure pumps only work as hard as needed.
Adding VSD logic control through your BMS (e.g., 180 kPa setpoint with floating adjustments) can dramatically lower consumption.
Regular testing of DP sensors, valve operation, and auto staging logic prevents energy spikes and stabilises flow rates across the building.
