Chiller Commissioning Checklist

A chiller commissioning checklist is used to thoroughly record observations before and after the start-up of chiller systems. Accurately capture suction, discharge, oil, and brine temperatures using Lumiform temperature sensors. Automate temperature monitoring of chiller systems, easily manage risks through proactive alerts to the right people when something goes wrong, and stay in control of your day-to-day operations.

Chiller Commissioning Checklist
Before Start-up
Read and understand all manuals (chiller, controls, etc.)
Read and understand manuals for third party components (electric motors, valves, etc.)
Check unit installation and vibration damper adjustment
Carry out functional testing of safety equipment
Read the opening pressures on all safety valves, and check that they are correct
Carry out vacuum test
Check Unisab set-up (see list of settings), and check VSD set-up, as applicable
Check oil level
Check that the heating element in the oil has been on for 6-8 hours before start
Take a sample of the primary refrigerant (must be free from water, air, etc.)
Check that the motor rotation direction is correct
Check that the coupling is aligned
Check that compressor cooling is connected correctly
Check that the plant is not leaking
Check that the valves are in the correct position for operation
After Start-up
Check that the capacity regulation system is working correctly
Check the refrigerant charge (at full load)
Check the unit for vibrations
Check the unit for vibrations using variable speed
Make a start-up log at full load
Take out a representative lubricating oil sample after about 1 hour of operation, and save it for minimum 1 year from commissioning date

A Comprehensive guide to ensuring proper chiller commissioning

A Chiller Commissioning Checklist is a valuable tool for a facility manager when commissioning a new chiller. It ensures that the chiller is properly installed and functioning correctly. The checklist can help a facility manager identify any potential issues before they become bigger problems and ensure that the chiller is operating at peak efficiency.

The checklist should include items such as checking the coolant, drain valves, and condenser coils. It should also cover items such as verifying the operating pressure, temperatures, electrical connections, and controls.

The checklist should be tailored to the specific chiller being installed and should be reviewed with the installation team before the chiller is commissioned. This allows the team to make sure that all components are functioning properly and that the chiller is ready for operation.

Using a Chiller Commissioning Checklist can help a facility manager save time and money by avoiding potential problems and ensuring that the chiller is running at the best possible efficiency. It also allows a facility manager to keep better records of the installation, which can help in the event of future maintenance.

Please note that this checklist template is a hypothetical appuses-hero example and provides only standard information. The template does not aim to replace, among other things, workplace, health and safety advice, medical advice, diagnosis or treatment, or any other applicable law. You should seek your professional advice to determine whether the use of such a checklist is appropriate in your workplace or jurisdiction.
