A Maintenance Guide to Prolong Your Commercial Chiller’s Service Life08 November 2022
The operations of commercial buildings can only become successful if they invest in the right equipment pieces and tools. Chillers, for instance, are maximised to negate the thermal energy generated by other equipment pieces and so on.
Commercial chillers often work by moving heat from one area to another. The heat these things remove often comes from either the process equipment or the product itself. Once the heat is obtained, the chillers would then transfer it to a place outside of the facility. Most chillers can be found on the roof part of commercial buildings. And as these things operate, they can provide significant savings in energy bills while retaining optimal air conditioning.
If you are currently maximising this equipment in your commercial building, you must maintain it properly to prolong its service life and obtain its benefits. Here are some things you need to do to effectively maintain your commercial chiller.
Keep the Condenser Water Clean
One of the things you must do to prolong the service life of your chiller is to keep its condenser water clean. The condenser water often features minerals and other elements that can be damaging to your chiller. If left untreated, it can gradually cause corrosion and scaling inside your chiller. Treating the condenser water can prevent damaging elements from building up on your equipment and generating higher condenser pressures. Doing this can also avoid inconsistent water temperature and water flow.
Clean the Tubes Once a Year
Tubes are essential in chillers since they serve as the main route for heat transfers. Without cleaning them regularly, they might be quickly filled with contaminants and impurities that can often increase thermal resistance. To clean the tubes of your chiller, you must brush them at least once a year. You may also have to maximise a monitoring system so you can check the condition of your chiller tubes and other vital components. Once the system detects tube issues, you can easily clean them before more problems arise.
Regulate Water Flow and Temperature
Increasing the temperature of the condenser water has been proven to make chillers more efficient. If your chiller is equipped with variable speed drives, you can expect it to perform 10 to 15% better when utilised with warmer condenser water. A chiller that runs at constant speed can, alternatively, gain about 5% efficiency when using the same water quality. As for its flow, the water should move above 3 feet per second and below 12 feet per second. These values can prevent vibration and noise from coming out of your chiller.
Conduct an Oil and Filter Change
To keep your chiller optimised throughout its operation, you must conduct an oil and filter change after the first year of its use. You must also analyse the oil to pinpoint the frequency required in changing the oil in the future. If the oil tends to get dirty, you must change it more frequently. Spectrometric chemical analysis is also advised when studying your oil condition.
Inspecting and checking your fan control system, evaporator water temperature differential, condenser and evaporator pressures, safety control settings, and operating control settings are some more things you can do to maintain your chiller.
