Key Findings
- ● 17.3% of operating hours classified as inefficient (plant kW/ton > 4.0)
- ● Inefficient hours cluster at low wet-bulb (median 11.9°C) and low load (median 96 tons)
- ● Power floor estimated at ~142 kW with incremental cost of 2.87 kW/ton
Systematic investigation of low-delta-T syndrome: configurable threshold analysis, quantile-based fault flagging, efficiency classification, power floor detection, and identification of the worst-performing operating hours.
