Open Circuit Cooling Towers

Introduction:

In Open Circuit Cooling Towers, there is a direct contact between the water to cool down and the air.It is a heat exchanger that in order to cool down water makes use of the direct contact with the air. The heat transfer occurs partially thanks to a heat exchange between air and water, but mainly thanks to the evaporation of a small quantity of the water that needs to be cooled. This will allow to cool down to a temperature lower than the ambient temperature.

Operation of Open Circuit Cooling Towers:

Process

Open circuit cooling tower is an enclosed structure that distributes warm water over a labyrinth-like packing, or fill, which provides an expanded air-water interface for heating of the air and evaporation to take place. The water is cooled as it falls through the fill, and is then collected in a cold water basin below. The heated moisture-laden air leaving the fill is discharged into the atmosphere.

It discharge heat from water-cooled systems into the atmosphere. The hot process water is distributed over a fill pack (heat transfer media) to interface with air blown by a fan through the cooling tower. During this evaporative cooling, a small part of the water evaporates while cooling the remaining process water.

Benefits

Configurations

There are two main configurations of factory assembled open cooling towers: crossflow and counterflow. In crossflow cooling towers, the water flows vertically down the wet deck as the air flows horizontally across it. In counterflow cooling towers, the water flows vertically down the wet deck as the air flows vertically up it.
