What is a Cooling Tower and How Does it Work?

What is a Cooling Tower and How Does It Work?Cooling Towers are used in industrial operations varying from HVAC systems to nuclear power plant facilities and petroleum refineries. Accordingly, their sizes range from small factory-assembled pieces to large field-erected towers capable of rejecting thousands of BTU of heat.

While the applications, sizes, and shapes of Cooling Towers will vary, the purpose and principle of operation remains the same.

What is the Purpose of a Cooling Tower?

A Cooling Tower is used with industrial applications that produce waste heat as a byproduct of their operations. These applications may include air-conditioning, manufacturing, and power generation. Cooling Towers provide an energy efficient and environmentally-friendly means of rejecting that waste heat, saving our natural bodies of water from receiving vast quantities of warm water that would threaten marine life and ecology. They work instead to dissipate evaporated water into the atmosphere, allowing wind and air circulation to diffuse the heat.

How Does a Cooling Tower Work?

Warm water from the heat source is pumped to the water distribution system at the top of the cooling tower. The water is distributed over the wet deck fill by means of nozzles. Simultaneously, air is drawn through air inlet louvers and through the wet deck surface causing a small portion of the water to evaporate. The evaporative process removes heat from the water. The warm moist air is drawn out of the top of the tower through a natural draft or mechanical cooling tower fans controlled by gearboxes. The resulting cold water is then recirculated back through the heat source in a continuous cycle.

Maintaining Efficiency of a Cooling Tower

The internal components of the cooling tower, including the fans, gearboxes, fill, and nozzles represent the core of the heat transfer efficiency. Due to the harsh and humid environment within a cooling tower, the internal components can wear out or even become outdated if the process has been altered or expanded. Each component has its own purpose and principle of operation specifically suited to operating conditions.
