Understating Different Types of Cooling Towers

The heat that Industrial processes and machines generate is immense. As such, continuous dissipation is vital for efficient operation. Typically, cooling towers remove excess heat from the water and dissipate it to the environment.

Though cooling towers have been around since the 20th century, there is little knowledge about them.

How a Cooling Tower Works

Warm/hot water from industrials processes enters the cooling tower and spread to the top evenly. As the water trickles down through the tower, the tower fill spreads it over a large area. This increases contact between air and water. As a result, the heat evaporates from the water, causing cooling.

The cooling tower has large fans that ensure that air continuously flows along with the fill. This air is water cause evaporation, and thus, water loses heat. The cool water enters the tower sump at the bottom, where it goes to heat the primary heat source.

The system allows for dilution. Therefore, some water leaves for the drain via the bleed-off valve. Cooling tower manufacturers in Bangladesh adds a make line. This line feeds freshwater to the system.

Types of cooling towers

There lots of cooling towers in Bangladesh. But most people three types. They differ based on how the water of air passes through them. Take a look:

Counterflow cooling towers

Here air flowing into the system follows a vertical route over the splash fill. But the water flows downwards from the above reservoir.

These cooling towers are smaller than the crossflow but more expensive. Air moves upwards against down flowing water. This process requires more energy, which makes it expensive.

Crossflow cooling towers

This cooling system utilizes a splash fill. The splash fill allows inflowing air to move over horizontally over a stream of water.

Though expensive, these systems are easier to maintains but more vulnerable to frost.

Hyperbolic cooling towers

Hyperbolic Cooling towers are an excellent option for large scale tasks. They are efficient in huge chemical and power plants.

These cooling towers have nice designs and need a minimal amount of resources to run them. Typically, they use a chimney stacking technique to dissipate heat.

In the system, cooler air on the outside pushes the warm damp air inside the tower. The splash fill is at the bottom. Still, the system has upward flowing air, which cools water that sprays on the splash fill.

For industrial cool, cooling towers are very effective. However, you need to find a cooling tower in Bangladesh that suits your application. Besides, it vital to monitor efficiency. An efficient system saves energy, reduces operating costs, and reduces water consumption.
