This is where water efficiency is truly won or lost. As water evaporates, it leaves behind minerals like calcium, magnesium, and silica. If these minerals are allowed to concentrate, they will scale the heat exchangers and destroy the system.
The efficiency of this process is often measured by the . This is the ratio of the concentration of dissolved solids in the tower water compared to the fresh makeup water. Low Cycles (2-3): High water waste. cooling tower water consumption
This is the pump flow rate (GPM - Gallons Per Minute). This is where water efficiency is truly won or lost
Increasing CoC is the low-hanging fruit of water conservation. The efficiency of this process is often measured by the
In the world of industrial processing and HVAC systems, cooling towers are the unsung heroes of thermal management. They are incredibly efficient at removing waste heat, but that efficiency comes at a price:
Several opportunities exist for reducing cooling tower water consumption, including:
As water cascades through the tower, a small portion evaporates, removing latent heat. This is the intended heat rejection mechanism. Typically, 1.8–2.0 gallons of water evaporate per ton-hour of cooling (or ~1.0–1.2 L per kWh of heat rejected). Evaporation accounts for 70–90% of total water consumption.
