- Configure and calibrate control panels, sensors, and safety devices.
- Conduct system performance checks including delta‑T measurement, flow rate verification, and pressure testing.
2. Chiller Maintenance & Repair
- Perform routine and preventive maintenance on chiller plant components such as:
- Compressors
- Heat exchangers (evaporator & condenser)
- Cooling towers
- Pumps, motors & VFDs
- Expansion valves & refrigerant circuits
- Handle refrigerant charging, leak detection, and recovery per EPA/ASHRAE standards.
- Conduct chemical cleaning, descaling, and tube brushing of condenser & evaporator tubes.
3. Diagnostics & Troubleshooting
- Diagnose faults using advanced tools like:
- Manifold gauges
- Vibration analyzers
- IR thermography
- BMS/PLC control systems
- Resolve major issues such as chiller trips, high/low-pressure faults, oil circuit problems, and refrigerant imbalance.
- Interpret wiring diagrams, control schematics, and OEM manuals.
4. Chiller Plant Operations
- Monitor and optimize chiller plant parameters:
- COP / kW‑TR
- Water flow balance
- Chilled water and condenser water temperatures
- Energy efficiency
- Ensure integrated operation with AHUs, FCUs, and ventilation systems.
5. Documentation & Reporting
- Prepare detailed service reports, maintenance logs, and breakdown analysis.
- Maintain records of refrigerant usage, spares, and critical consumables.
- Provide recommendations for system upgrades and energy efficiency improvements.
6. Client Interaction
- Explain technical findings to clients and provide preventive maintenance guidance.
- Ensure professional behavior and maintain strong customer relationships.
- Train client teams on basic chiller system care and safe operation.
