Typical chilled water cooling temperature ranges between 39-45 F. For proper heat transfer between the circulated water to be cooled and the refrigerant, it is important to maintain sufficient chiller water flow. The commonly recommended range of chilled water flow velocity is between 3 and 12 feet per second.
