Adiabatic coolers are a modern, low risk to hybrid and traditional cooling towers, involving significantly lower maintenance and OPEX.
An adiabatic cooler applies the principle that when the pressure applied on a parcel of air is reduced, the air in the parcel is allowed to expand; as the volume increases, the temperature falls as its internal energy decreases. In an adiabatic air cooler air is drawn across the coil by the fan. As the warm air encounters the wetted pad or water spray, the air temperature is reduced adiabatically thus allowing sensible cooling of the coil below the ambient dry bulb temperature.
When the ambient temperature is below the set-point for the fluid being cooled, the cooler operates in dry mode, with the fans drawing ambient air across the coil to cool it. As the ambient temperature rises, it can no longer achieve the desired cooling and the cooler switches to adiabatic mode to reduce the temperature of the incoming air.
With intelligent control it is possible to balance the use of the fans and water delivery to achieve either reductions in water consumption or energy.
