We will learn about evaporation towers and the simple physical principles they apply to maintain high performance. We will also look at how they are built and the criteria for determining their size. Finally, we will explain in detail how cooling towers work and how they work in principle, using examples, texts, images and diagrams.

A cooling tower is a heat separator that uses water to transfer and process waste heat from the atmosphere. This is a special type of heat exchanger which allows water and air to come into contact with each other thereby lowering the temperature of hot water. Cooling towers work on the principle of extracting heat from the water by evaporating a small part of the water, which is then fed back through the tower.

A cooling tower is a structure that uses water evaporation and air flow to remove excess heat from industrial plants and HVAC systems. The mixing of warm water with cooler air releases latent heat through evaporation, which cools the water. Cooling towers use the cooled water in huge heat exchangers to dissipate the heat accumulated in the atmosphere and return the cold water back to the cooling system.

Cooling towers are essential for power plants, factories, refineries, processing plants, hotels and other facilities rely on water circulation to keep heat away from buildings and machinery.

The primary use of large industrial cooling towers is to eliminate the heat absorbed by circulating cooling water systems used in power plants, oil refineries, petrochemical plants, natural gas processing plants, food processing plants, semiconductor plants and other industrial facilities such as condensers distillation columns for cooling liquid crystallization. Industrial cooling towers are also used to extract heat from various sources such as machines and heated process materials. They are an effective way to remove unwanted heat from a location and use water as a transport medium for applications that require reliable cooling water in the temperature range of 70 to 100 degrees all year round.

Cooling towers are used to cool products and machinery in a variety of applications, including injection molding, punching, food and beverage chemicals, laser tools, semiconductors and more. Cooling towers require special maintenance to ensure safe, efficient and reliable operation, including effective water treatment programs. Plant owners and operators can work and maintain their plants more efficiently by understanding how cooling tower systems work.

Cooling towers rely on fans, sprays and pumps to allow water to evaporate and, in some cases, on natural traction (air movement) to dissipate and process heat. Hot water from the ducts of industrial machinery and HVAC systems is sprayed and spilled into the area where it evaporates and the rest accumulates in a basin lowering the total temperature of water in the cooling tower.

The air in the cooling system is an active ingredient of the water in the cooling system, as the water expels heat from the tower at the wet bulb temperature. The counter-current tower absorbs the water injected to warm the air and flows it to the top of the tower.

HVAC towers (heating, ventilation, air conditioning and cooling) are used to dispose of unwanted heat from refrigeration systems. Traditional HVAC heating and cooling systems are used in schools, large office buildings and hospitals. HVac uses one cooling tower or two cooling towers: a water-cooled cooling system and a water-cooled condenser.

After a cycle of central air conditioning, the heat from a room in the building is converted into cold water, which is then converted into cooling water. Wet cooling towers or open cooling towers are used in water-cooled systems in which heat transfer is measured by decreasing the process temperature and thus increasing the moisture content (Wet bulb temperature) of the air flowing through the cooling tower.
