A chiller can generally be classified as being a refrigeration system whose role is to chill a liquid. When water is cooled, it can be used for a variety of applications, including enhancing user comfort and optimizing industrial processes.


There are different ways to improve a chiller’s efficiency and therefore reduce its operating costs:

  • Reduce the condenser water temperature
  • Maintain adequate water flow to the condenser
  • Increase the temperature of the cooled water
  • Reduce auxiliary equipment energy requirements
  • Use outside air to cool (“free cooling”)
  • Combine different types of chillers for maximum efficiency
  • Put heat recovery systems in place
  • Use a motor frequency converter
  • Use ice bank technology
  • Keep tubes unclogged
  • And many others
