Water cooling towers are a few varieties that are used in industrial areas and social areas.
With the fan deck located at the top of the water cooling tower, the air is forced out from the louvres first, then forced out through the cooling tower padding.
These types of towers, which are generally preferred in small capacities and small areas, have a very wide use area. With modular construction, shipments and assemblies are very easy.
The sound effects can be reduced by changing fan structures, revolutions, diameters and chimney structures. 85 dB is the standard sound levels at a distance of 3 meters. it can be reduced to 65 dB with adders.
Another structure similar to the cooling towers is the evaporative condenser. In these structures, the outside air and operating water do not come into direct contact with each other. In some cases fountain water is used to increase the effect of outdoor cooling.
In this system, where the fan is located at the bottom of the tower, counterflow towers, the water coming down to the water to be cooled, the water cooling tower is brought into contact with the water at the filling surface and this counterflow increases as the amount of incoming water decreases. These towers, which require higher horsepower than the axial traction towers with axial fans, have higher energy use.
Naturally pulling towers are the ones where natural air flow is used without using any gravity traction. Such towers, where no radial or axial fan is used and require very high air flow and water passages, are used in installations such as power generation plants. These towers, which are very high in structure, are generally made of concrete and shaped like a vase and work according to the principle of surface evaporation.
