Cooling tower water use
From the course: Cert Prep: LEED Green Associate
Cooling tower water use
- In addition to indoor and outdoor water consumption, the LEED rating system addresses water used by condenser water systems. A cooling tower uses water to remove heat by evaporation. As the water absorbs heat it evaporates, and the salt solids become more concentrated in the remaining water. To prevent this build up that may result in significant damage to equipment, such as corrosion or scaling, cooling towers deposit the remaining water which is called a blow down process. Then, they take in plenty of fresh water to makeup for the losses and repeat this process many times. As a result, cooling towers can be responsible for large portions of a building's total water consumption. Cooling tower water use credit encourages conservation of water used for cooling tower makeup while controlling microbes, corrosion, and scale in the condenser water system. The first step in reducing cooling tower water use is engaging a water treatment specialist to perform a potable water analysis. Then…
