How to Maintain Chiller Efficiency in Easy Steps?
For many commercial buildings, chillers are the largest single energy users or we can say the heart of HVAC system and assuring that they’re running efficiently should be a top worry.Due to advances in controls,refrigerants and equipment design,chillers now have tighter operational strength.Maintenance and engineering managers should consider these steps for ensuring that the chiller is reliable and energy efficient.
- Daily Log to Maintain
It's important for operators/engineers to keep the record of chiller performance daily with an accurate data. This is the best way to compare data in order to detect problems or ineffective control set points.Maintaining a record allows the operator to assemble a history of operating conditions,which can be considered to determine flow.
- Maintain Cleanliness
This sounds like a simple one,but that doesn't undercut its importance.Chiller efficiency lowers as tubes become dirty over time with mud,algae,sludge or contaminants.The rate of deterioration depends on the system type as well as on water quality,cleanliness and temperature.
- Test for Leaks
Moisture in a chiller can create acids that corrode motor windings,causing rust to form inside of the shell.These small rust particles are called "fines" and become trapped inside the heat-exchanger tubes.Fines decrease the unit's heat-transfer effectiveness and overall efficiency.If proper maintenance isn't performed,this could lead to costly tube repairs.
The best way to monitor leaks in a low-pressure chiller is to track purge-unit runtime and the amount of moisture quantity at the purge unit.If the figures test as too high,then the unit could have leaks.
- Analyze Oil & Refrigerant
An annual chemical analysis of oil and refrigerant can detect chiller contamination problems before they become a serious issue. A qualified chemical technician that specializes in HVAC equipment must perform the analysis to ensure proper safety measures are being practiced.
