Chilled water plant room with large insulated pipework

Key findings

  • VFDs, chillers T/P, cooling tower pumps and fans are controlled manually (not PLC-controlled)
  • Overall system COP ≤ 3.1
  • 30% of temperature sensors defective (inconsistent readings)
  • BTU meters reading only the main supply line
  • Inconsistent BMS connections to the chillers
  • Existing control system (Siemens S7 Industrial PLC) partially out of service
  • Critical power quality parameters (low PF, high harmonics, failing capacitors)
Recommended improvement workplan
  1. Starting point: COP ≤ 3.1
  2. Maintenance of assets
  3. Power quality correction9% savings
  4. Flow control (pumps)45% savings
  5. SCADA optimization46% savings
  6. Result: COP ≥ 3.813–18% savings
