Chiller System Design Focus: Chilled Water Pumping System
The chilled water pumping system is the circulatory backbone of a chiller plant, responsible for delivering cooling from the chiller evaporator to air handling units (AHUs) and fan coil units (FCUs).
Key Design Components
Chilled Water Pump (Primary / Secondary)
Supply & Return Headers
Balancing Valves & Isolation Valves
Strainer (Pump Protection)
Differential Pressure Sensor
Expansion Tank
Variable Frequency Drive (VFD)
Operating Principle
Chilled water exits the evaporator at ~6-7°C
Pumps circulate water through the distribution network
Heat is absorbed at AHUS/FCUs
Warmer water (~12°C) returns to the chiller for re-cooling
Energy Efficiency Strategy
Use VFD-controlled pumps
Maintain constant differential pressure
Enable variable primary flow (VPF) where applicable
Correct balancing to maintain system AT and avoid low AT syndrome
Maintenance & Reliability Considerations
Regular strainer cleaning
Seal and bearing inspections
Verify DP sensor calibration
Monitor vibration and motor current
Why This Matters
A well-designed chilled water pumping system:
Improves chiller efficiency
