Cooling Tower

<p>A cooling tower uses evaporative cooling to reject heat from the condenser water loop of a chiller plant. Warm water from the chiller condenser is distributed over fill media inside the tower; ambient air drawn through by fans causes a fraction of the water to evaporate, removing latent heat and cooling the remaining water before it returns to the chiller condenser.</p><p>Cooling towers are highly effective in hot climates but consume significant quantities of water — a major consideration for WUE. Drift eliminators limit water loss to atmosphere. Legionella risk management (dosing, blowdown, regular testing) is a legal requirement in the UK under the HSE Approved Code of Practice L8. In humid climates, dry coolers or adiabatic coolers are sometimes preferred to reduce water consumption.</p>
