Cooling tower efficiency is limited by the ambient wet bulb temperature. The calculation of cooling tower efficiency involves the Range and approach of the cooling Tower. Range = Hot Water Temperature – Cold Water Temperature The difference between the Hot Water Temperature (Cooling Tower Inlet) Temperature and Cold water (Cooling Tower Outlet) temperature is called Cooling Tower Range. The difference between the Cold Water Temperature (Cooling Tower Outlet)Īnd ambient Wet Bulb Temperature is called as Cooling Tower Approach.Īpproach = Cold Water Temperature – Wet Bulb TemperatureĬooling Tower approach is the better indicator of the performance. We shall see those terminologies in Detail. The performance of the cooling tower depends on various parameters like Range & Approach. They reject process heat from the cooling water to atmosphere and keep the water cool. Cooling Tower plays a major role in Chemical Process Industry.
