The heating and cooling industry is big business with a global market size of $240.8 billion in 2019. An industrial-grade commercial chiller costs a pretty penny, so the longer you can go without needing a replacement the better.
Keeping commercial equipment in good working order takes more knowledge and skill than most people realize. That is why we put together this quick guide covering maintenance tips for your company's commercial chiller. Keep reading to keep your chiller chilling for many years to come.
Five Best Maintenance Tips
When the chiller is brand new or recently installed the tendency is to not worry about maintenance, sometimes for years. This is a common mistake.
Industrial chillers protect temperature-sensitive goods which are often quite valuable so a breakdown and any subsequent downtime is a major expense. Keep your chiller up and running at peak performance with the following tips.
1. Clean Tubes Often
When the tubes get dirty it affects heat transfer efficiency. Tubes should be cleaned out often to remove unwanted minerals, scales, mud, and algae. Look out for increases in high approach temperatures as this indicates your heating efficiency may decrease due to dirty tubes.
2. Only Use Treated Water
Some HVAC maintenance can be avoided by using treated water in the condenser. When untreated water is used in the condenser water loops fouling happens.
Bacteria will grow and compromise the effectiveness of the tubes. Inspect and clean chilled water loops at least once a year.
3. Protect and Silence
Consider taking steps to protect the outside of your equipment as well. Chillers are huge and tend to run rather loud. Fitted acoustic blankets are perfect for reducing chiller noise as well as keeping your equipment free of grime and dust buildup.
4. Keep Good Refrigerate Charge
The ideal refrigerant charge is enough charge to keep the desired environment while running the condenser at optimal efficiency. Inspect your equipment for leaks and make sure air and moisture aren't being introduced into the system.
Low pressure refrigerate charge forces the compressor to work harder while cooling less. Too much charge and you are only wasting energy. Find and keep the ideal amount of refrigerant moving throw the main compressor to most efficiently cool the space.
5. Monitor and Log Performance Readings
Recording the daily operations of the chiller allows you to find that sweet spot where the chiller performs at its best. By monitoring temperature, pressure, fluid levels, and flow rate it is possible to detect potential maintenance issues early before they cause a breakdown.
Maintenance Tips Worth Knowing
Being in charge of keeping a chiller running efficiently is a more complicated job than you might think. Yet, if you follow the above maintenance tips and keep a close eye out for any potential problems, industrial chillers tend to go strong year after year.
