Average result across the alternating operating window.
Reported average energy reduction during compared operation.
Aggregate savings for the evaluated operating window.
Plant profile
Two-chiller office plant with variable-speed pumps
The plant normally operated one magnetic-bearing chiller, one variable-speed chilled-water pump, one variable-speed condenser-water pump, and two fixed-speed cooling towers.
Equipment
Operating equipment
The active equipment set was small enough for direct supervisory setpoint optimization.
| Equipment | Quantity | Specification | Status |
|---|---|---|---|
| Magnetic-bearing chiller | - | 1010 kW cooling capacity / Rated efficiency 0.57 kW/ton | Running |
| Chilled-water pump | - | 22 kW / 32 m head / 160 m³/h flow | Running |
| Condenser-water pump | - | 18.5 kW / 20 m head / 200 m³/h flow | Running |
| Cooling towers | 2 | 7.5 kW each / 350 m³/h flow | Normally open |
