How do you inspect a chiller?
Fresh air dampers for an air-cooled chiller system should be inspected in the same way as return air dampers.
- Preventive Maintenance for Industrial Chillers.
- Maintain your Daily Logs.
- Keep the Chiller Tubing Clean.
- Reduce the Temperature of the Condenser Water.
- Inspect the Condenser Water Loops.
- Monitor for Refrigerant Leaks.
How do you operate a chiller?
The high-pressure gas enters the condenser where ambient air or condenser water removes heat to cool it to a high-pressure liquid. The high-pressure liquid travels to the expansion valve, which controls how much liquid refrigerant enters the evaporator, thereby beginning the refrigeration cycle again.
What are the maintenance required for chiller?
Chillers should be tested for leaks, control operation and water quality weekly as well. Items such as load balances and limits can be inspected twice a year. A thorough cleaning, electrical system inspection, and other maintenance tune-ups should be performed annually.
What do you check in a chiller?
CHILLER MAINTENANCE CHECKLIST AND DAILY LOGS
- Note refrigerant and oil levels.
- Inspect fan control system.
- Check evaporator water temperature differential.
- Measure condenser fan motor volts/amps, where applicable.
- Check water flow through evaporator.
- Measure condenser and evaporator pressures.
- Check operation of controls.
How the chiller system is working?
How Does a Chiller Work? A chiller works on the principle of vapor compression or vapor absorption. Chillers provide a continuous flow of coolant to the cold side of a process water system at a desired temperature of about 50°F (10°C).
How do you start a water cooled chiller?
5.1 FOR STARTING CHILLERS
- Ensure inlet and outlet valves of condenser cooling water pump; primary and secondary chilled water pumps are open.
- Ensure inlet and outlet valves of condenser and evaporator pipeline at chiller are open.
- Ensure water is available in balancing tank and cooling tower.
How do you maintain a chiller efficiency?
3 Ways To Increase Chiller Efficiency
- Consider variable speed retrofits. Most components within a chilled water system will benefit from variable speed drives.
- More is less: Running multiple parallel devices optimizes savings.
- Increase supply temperatures.
