Step 4: Sustain proper water treatment - A water treatment program can help maintain efficiencies between cleanings.Refrigerant levels can be tracked by using an air-purge time, checking the refrigerant sight-glass for bubbles, and using a gas analyzer to assess all the joints and connections. Keep refrigerant levels within the manufacturers’ recommendations. It also means that hazardous refrigerants are released into the air. Step 3: Ensure a leak-free unit - In addition to scale, leaks can also be detrimental to the efficiency and operation of the system.Goodway has a selection of chemical descaling solutions, mechanical tube cleaning solutions, and expert consulting services to find the proper cleaning approach. Pressure loss can also indicate tube corrosion. It is recommended to clean chiller tubes at least once a year, but regular monitoring can help identify when cleaning should take place. Even the smallest amount of scale can add thousands of dollars in additional energy expenses.
Step 2: Keep tubes clean - The presence of scale and fouling can greatly impact efficiency.This data will help raise any red flags in the case something needs to be addressed. If four times a day is unfeasible, a minimum of once a day is suggested. Step 1: Maintain a daily operating log - The Federal Energy Management Program (FEMP) recommends updating the log four times a day to monitor key operating parameters that will help indicate if any problems are developing.Goodway Technologies is sharing the following best practices to help improve chiller performance: What steps can you take to improve your chiller maintenance?Ī chiller maintenance plan or checklist is an ideal way to proactively stay on track and ensure your equipment is operating efficiently. If your chiller has to work harder to reach the desired output, it will require more power and increase energy costs. Chiller tubes are susceptible to the buildup of scale and other sediments and residue. This means any inefficiencies can have a big impact on the bottom line. Department of Energy, 35% of a building’s total energy use comes from its heating, ventilation and air-conditioning (HVAC) system. While it can be easy to defer maintenance for a variety of reasons, whether it be labor, budget or other priorities, there are costs associated with skipping maintenance, reminds Goodway.Īccording to the U.S. Why is chiller maintenance important?Ĭhiller tubes are susceptible to the buildup of scale and other sediments and residue. The practice is even more important this year, as some facilities may have seen periodic shutdowns or closures over the past year and a half, notes Goodway. By Brianna Crandall - FebruIn these cooler months, maintenance solutions provider Goodway Technologies is reminding facilities managers (FMs) of the importance of properly cleaning and maintaining chiller systems.
