6. Operational Efficiency
- Use calibrated thermometers for accurate readings.
- Record temperatures at regular intervals.
- Compare readings against operational benchmarks.
- Investigate any significant temperature variations.
- Use a flow meter to measure the water flow.
- Compare flow rates to manufacturer specifications.
- Adjust valves if necessary to achieve optimal flow.
- Document flow rate readings for future reference.
- Create a log to document anomalies.
- Include date, time, and specific observations.
- Prioritize issues based on severity.
- Communicate findings to the maintenance team.
- Observe the bleed-off rate during operation.
- Adjust the cycles to minimize water loss.
- Verify that the cycles match the cooling load.
- Monitor for signs of over-cycling.
- Calculate the temperature differential accurately.
- Ensure the differential aligns with design parameters.
- Investigate large differentials for potential issues.
- Document findings for trend analysis.
- Visually inspect fill media for dirt, algae, or scale.
- Perform a clean if fouling is detected.
- Check for uniform water distribution over the fill.
- Replace fill media if severely degraded.
- Listen for unusual sounds indicating malfunction.
- Measure fan speed with a tachometer.
- Inspect fan blades for damage or obstructions.
- Lubricate bearings as per manufacturer recommendations.
- Inspect drift eliminators for wear and tear.
- Ensure they are properly aligned and sealed.
- Clean if fouling is evident.
- Replace damaged eliminators promptly.
- Use hygrometers and thermometers for readings.
- Record ambient conditions regularly.
- Analyze how changes affect cooling efficiency.
- Adjust operations based on ambient data.
- Conduct a visual inspection of ductwork and seals.
- Use smoke tests to identify leaks.
- Seal any identified leaks promptly.
- Regularly review the system for integrity.
- Check water supply valves for proper operation.
- Measure the temperature of the make-up water.
- Ensure water quality meets operational standards.
- Document any issues with the supply.
- Use sound level meters to measure noise levels.
- Listen for irregular sounds from mechanical components.
- Investigate sources of excessive noise.
- Record findings for future assessments.
- Inspect insulation on pipes and equipment.
- Replace any damaged or missing insulation.
- Check for heat loss in key areas.
- Ensure insulation is appropriate for the system.
- Visually inspect surrounding areas for debris.
- Clear any obstructions from intake and exhaust areas.
- Ensure no vegetation is encroaching on the tower.
- Document any obstructions and corrective actions.
