PART 1 –
Provides a comprehensive overview, including general discussion of centrifugal water chillers and includes the following topics:

  • Introduction to Chilled Water Systems and Centrifugal Water Chillers.
  • Components – compressor, motor, condenser, evaporator, purge and controls. Refrigeration cycle covering system operation.
  • Compressor Capacity Control – inlet vanes, impeller dynamics, compressor unloading, surge and adjustable frequency drives.
  • Maintenance Considerations – general maintenance requirements of a centrifugal water chiller including importance of maintaining related pumps and cooling towers.
  • Mechanical Considerations – reviewing operating logs and trends, observing oil pressure drop, monitoring evaporator and condenser approach temps, observing and recording the oil level, monitoring purge pump-out operation.
  • Application Considerations – Condensing temperature control, cooling tower bypass, constant or variable flow, heat recovery and ARI Standards.

PART 2 –
A continuation of the Trane CenTraVac Operator – Part 1 course covering the area of troubleshooting including:

  • Understanding of chiller logs and the identification of problems
  • Preventative maintenance
  • Inspections required to monitor and maintain system efficiency and safety
  • Water treatment
  • Refrigerant
  • How to troubleshoot:
  • Air in the machine
  • Low condenser water flow
  • Fouled evaporator tubes
  • Condenser water bypassing condenser tubes
  • Bypassing chilled water tubes
  • Low chilled water flow
  • Fouled condenser tubes
