A chiller is a device that provides cooling in centralized systems. They work in tandem with HVAC systems to cool spaces in a facility. They also help cool equipment, which is especially critical in data centers to ensure consistent operation. They are extremely versatile and flexible.

The mechanism of chillers relies on ideal gas laws and thermodynamic principles to remove heat from the targeted space. A liquid called coolant circulating in the chiller cools the space by absorbing the heat and discharging it into water or air.

Most buildings use chillers as a central cooling system to keep the entire building comfortable throughout the summer. However, a chiller plant can only operate efficiently if all components are working properly. Chillers often account for a facility’s largest peak load and can consume nearly half of a building’s total energy consumption. Fortunately, managers can take several steps to optimize chiller operations and energy efficiency without compromising safety or occupant comfort.

The most important step in optimizing chiller operation is making sure all components are properly sized to meet cooling needs. It is also crucial to pay attention to part-load efficiency and look for opportunities to save energy in the overall system. To do this, it is essential to have a well-designed and documented maintenance program that includes regular inspections of coils, tubes, pumps, and controls. In addition, it is essential to purge air from the refrigerant loops and to track run time on a daily basis. These simple changes can greatly reduce the energy costs associated with a chiller plant, while improving chiller performance. chiller
