What is a Cooling Tower?

2008 358

Simply put, a cooling tower is an equipment used to cool water via means of evaporation. Water is one of the most abundant fluids in the world, covering over 70% of the earth surface. A key characteristic of water is its ability to easily and effectively absorb and dispel heat into the atmosphere. Cooling Towers take advantage of this, and through decades of development remains one of the most efficient and cost effective cooling systems in the world.


How is cooling achieved in a Cooling Tower?

Matrix---Basic-Cooling-Tower-DiagramIn a cooling water system, heat is transferred from a heat source (usually factories, industrial plants or air conditioning systems) via heat exchangers to circulating water. This hot water is channeled to the cooling tower to be cooled.

In the cooling tower, the hot water is cooled down via evaporative cooling. Cooling Towers are designed to maximize evaporation of the water by increasing the surface area of the water through a water distribution system (usually sprayers) and a heat exchange surface (called infills). Cold air from the atmosphere is drawn into the cooling tower to pick up the heat and releasing it into the atmosphere.

It is most cost effective and thermally efficient cooling methods available.


What type of Cooling Towers are there?

Generally, cooling towers fall under one of two categories:

  • Counterflow Cooling Towers
  • Crossflow Cooling Towers

Counterflow Cooling Towers

Counter Flow Cooling TowersIn counterflow cooling towers, air enters through the open area below the exchange surface and is drawn up vertically. Air travels vertically across the infill, opposite to the downward motion of the water. Hot Water is sprayed through the water distribution nozzles and flows downward through the infill, opposite to the air flow.

 

Crossflow Cooling Towers

Cross Flow Cooling TowersIn counterflow cooling towers, air enters through one or more vertical faces of the cooling tower, and it moves horizontally through the infill sheets. Hot water distributed over the tower by means of orifices in the hot water basin floor. The hot water flow down to the heat exchange surfaces by gravity and the air pass through the water flow into an open plenum chamber.


What are Cooling Towers made of?

Depending on its application, modern cooling towers can be built from different kinds of structural material.
