Since chilled water systems are quite complex, you need to carry out certain maintenance operations regularly to make sure they are always working efficiently and providing sufficient cooling to your large commercial spaces.Do you want to learn more? Check This Out
Tubes and refrigerant lines in chilled water system are likely to experience a buildup of scale and residue such as slime, mud, and algae over time. This can have a huge impact on the overall efficiency of the system. According to the U.S. Department of Energy, some chiller maintenance procedures should be performed at least once every year for smooth operation.
In this article, we’ll take a look at some tips you need to keep in mind when drawing up a chiller maintenance schedule.
Check for Leaks
The best way to find leaks in the refrigerant lines is through a refrigerant management program that assesses refrigerant use. Newer and more advanced chillers come with specially designed seals and pressure vessels that reduce refrigerant loss by 0.1 percent every year.
To enhance efficiency, you need to hire a technician to track refrigerant use or use hand-held detectors in order to find any leaks in the system. This will ensure that your chiller will operate at the highest possible efficiency throughout the year.
Make Sure the Tubes are Clean for Efficient Heat Transfer
Clean heat transfer is instrumental in maintaining high efficiency in your chilled-water systems. Contaminants like algae, minerals, mud, and other such impurities can build up inside the tubes and reduce overall performance. Higher approach temperatures indicators that your chiller’s efficiency is decreasing.
To prevent this, you need to clean the condenser tubes with a brush at least once a year or per your chiller maintenance schedule to make sure they’re free of contaminants that can affect indoor air quality.
Inspect Starters, Motors, and Electrical Connections
To ensure that the starters and motors are working efficiently, hire a technician to inspect the safety and sensor calibrations on the microprocessor controls. Moreover, you need to get the wiring, electrical connections, and switchgear checked for hot spots. It’s advisable to consult manufacturer’s guidelines to figure out what’s best for system maintenance.
