What is the normal fluid temperature drop through a chiller?

The normal fluid temperature drop through a chiller is commonly around 10°F. This is a typical design specification for many chillers to ensure effective cooling while maintaining system efficiency. The temperature drop indicates the ability of the chiller to absorb heat from the fluid being circulated through it, allowing the fluid to exit at a lower temperature than when it entered.

When designing or evaluating chiller performance, a 10°F drop is seen as a balance between optimizing energy use and achieving the desired cooling load. This value allows for sufficient cooling without placing excessive strain on the chiller, which can happen with larger drops. A consistent drop of about 10°F supports predictable system performance and efficiency, making it a widely accepted standard in the industry.
