chilled water system

Pre-Operational Checks

Inspect the chilled water system for any visible leaks or damages.

Verify that all valves are in the correct positions (open/closed) as per system requirements.

Ensure that the chilled water pump(s) are properly lubricated and functioning.

Check the power supply to the system and ensure it's stable.

Confirm that all safety devices are in place and operational.

Here are some additional steps that can be included in the Pre-Operational Checks section

Inspect the condition of insulation on piping to ensure there are no gaps or damage

Verify that the temperature and pressure gauges are calibrated and functioning correctly

Check the operation of the chilled water expansion tank and ensure it is properly pressurized

Ensure that the control panel is functional and that all indicators and alarms are operational

Inspect the strainers and filters for cleanliness and proper installation

Confirm that the refrigerant levels in the system are within specified limits

Check for proper flow through the system by ensuring that flow meters are operational

Ensure that all electrical connections are secure and free from corrosion

Test the operation of any automated control systems or building management systems (BMS)

Review system logs for any previous issues or anomalies before startup

Operational Monitoring

Monitor the chilled water temperature at the supply and return points.

Check the pressure readings on the system gauges.

Listen for unusual noises from the pumps and chillers.

Verify the operation of the cooling tower (if applicable).

Observe the flow rates and ensure they are within design specifications.

Here are some additional steps that could be included in the Operational Monitoring section of a New Chilled Water System Checklist

Monitor the power consumption of the chillers and pumps to ensure they are operating efficiently

Check the status and operation of any variable frequency drives (VFDs) associated with pumps or fans

Inspect the condition of insulation on chilled water pipes to ensure it is intact and effective

Verify that all valves in the chilled water system are operating correctly and are in the proper position

Monitor the ambient conditions and ensure that the system is responding appropriately to temperature changes

Assess the performance of any heat exchangers in the system for signs of fouling or inefficiency

Review the operation of the system control panels for any alarms or alerts

Track the overall system flow and return temperatures to evaluate system performance over time

Check for any leaks in the system, especially at joints and connections

Inspect the water quality in the chilled water system, including pH levels and conductivity, to prevent corrosion and scale buildup

Maintenance Procedures

Schedule regular cleaning of filters and strainers in the system.

Inspect and clean the evaporator and condenser coils as needed.

Test and calibrate temperature and pressure sensors periodically.

Check refrigerant levels and verify there are no leaks in the refrigeration circuit.

Review and update maintenance logs for any performed tasks.

Emergency Procedures

Ensure that emergency shut-off valves are accessible and operational.

Review the emergency response plan for the system.

Train personnel on emergency procedures and safety protocols.

Keep emergency contact information readily available.

Conduct regular drills to ensure preparedness in case of a system failure.

Documentation and Reporting

Maintain accurate records of inspections, maintenance, and repairs.

Document any issues or irregularities and the actions taken.

Review system performance reports regularly.

Ensure that all documentation is easily accessible for audits and inspections.

Update system diagrams and schematics as changes are made.
