COURSE OVERVIEW

 This practical and highly-interactive course includes various practical sessions and exercises. Theory learnt will be applied using our state-of-the-art simulators. 

 

This course is designed to provide participants with a detailed and up-to-date overview of O&M, Troubleshooting for Chiller 19XR Chiller. It covers the emergency handling and incident response; the compressor operation and configuration, evaporator and condenser design; the electrical system and control panel including safety devices and protection features; the pre-startup checks and procedures, startup and shutdown sequences and normal operation monitoring; the operating modes and load control, user interface and system parameters and operational best practices; the routine maintenance schedule, lubrication and oil management and refrigerant circuit maintenance; and the routine maintenance schedule, lubrication and oil management and refrigerant circuit maintenance. 

 

Further, the course will also discuss the tube cleaning and heat exchanger efficiency, electrical and control system maintenance and vibration and noise analysis; the root cause analysis process, symptom-to-problem mapping, troubleshooting flowcharts and documentation and reporting; and troubleshooting startup issues when chiller fails to start, interlock and safety trip conditions, phase imbalance and voltage drop and communication loss with controller. 

 

During this interactive course, participants will learn the surge detection and prevention, high discharge pressure, unusual noise or vibration and compressor motor trip; the evaporator and condenser problems covering insufficient cooling capacity, high approach temperature, chilled water flow issues and air or non-condensables in system, the electrical and control faults comprising of sensor failures and erratic readings, faulty relays or contactors, communication bus errors and controller reset or freeze; the carrier alarm codes, accessing alarm history, clearing and resetting alarms and trends leading to frequent alarms; and the energy efficiency and optimization, commissioning and system balancing, emergency handling and incident response.
