Cooling Tower - CED Engineering
A Cooling Tower is a heat rejection device that extracts waste heat to the atmosphere by cooling a stream of hot water in the tower. This type of heat rejection is termed "evaporative" because it allows a small portion of the water being cooled

beeindia.gov.incooling tower performance. Other factors, which we will see, must be stated along with flow rate m3/hr. For example, a cooling tower sized to cool 4540 m 3/hr through a 13.9°C range might be larger than a cooling tower to cool 4540 m3/hr through 19.5°C range. Range Range is determined not by the cooling tower, but by the process it is serving.
