High Efficiency Chilled Water Systems
Introduction to High Efficiency Chilled Water Systems
Chilled water systems are used to cool large commercial buildings. Making these systems more efficient is important because cooling may account for 15% of a large commercial building’s electric consumption. Chilled water systems include a chiller (air or water cooled), chilled/condenser water pumps and a cooling tower. Chilled water systems can offer a 30-50% greater operating efficiency than standard packaged air-cooled systems.
How High Efficiency Chilled Water Systems Work
High efficiency chilled water systems feature variable speed or multiple stage compressors, variable speed pumps and cooling tower fans that can adjust speed. They feature advanced BMS controls to adjust water temperatures and flow of the system based on the need of the building, improving system efficiency, and reducing electricity consumption. Each component of the chilled water system offers opportunities to improve efficiency and reduce operating costs.
