1. Compressor System Review
- Inspect compressor vibration levels and identify unusual patterns.
- Perform oil analysis for contamination, moisture, and acid levels.
- Check the alignment of compressor drive components.
2. Refrigerant System Analysis
- Test refrigerant pressure and adjust if necessary to ensure optimal charge.
- Inspect for refrigerant leaks using electronic detection tools.
- Review refrigerant circuit isolation valves and sensors for proper operation.
3. Electrical System Diagnostics
- Check electrical terminals and tighten as necessary.
- Test safety interlocks and overload protections for correct functionality.
- Inspect wiring insulation for signs of deterioration or damage.
4. Heat Exchanger & Water Circuit Inspection
- Clean evaporator and condenser tubes as needed for heat transfer efficiency.
- Measure water flow rates and pressure differentials across heat exchangers.
- Check performance of flow switches, temperature sensors, and related valves.
5. System Performance Audit
- Conduct performance testing under full and part-load conditions.
- Log and compare energy efficiency ratios (EER) with previous records.
- Submit a comprehensive monthly maintenance report to the facility manager.
