Cooling towers are a crucial part of any building’s heat and water management system. In this article, we’ll talk about what they are, where they’re used, and how they work. Read on!
Cooling towers are special heat exchangers that let water and air come in contact with each other to lower the temperature of hot water.
In this process, small volumes of water evaporate, lowering the temperature of the water circulating throughout the tower. The resulting colder water goes back to the equipment that absorbs heat or the condenser. This process happens over and over again to cool down heated equipment or condensers.
Cooling towers vary in size and design, but they mostly contain the following parts. Note that cooling tower upgrades are available for these parts.
Classifying cooling towers can be a bit complicated since one tower may have multiple classifications depending on its functionality. However, they can be classified according to the following:
With these factors in mind, the following are the most common classifications of cooling towers you may find in the market:
No matter what type of cooling tower you use, this piece of equipment is a vital part of a heat and water management system. If a single component stops working properly, it can significantly reduce the efficiency of your overall cooling system.
Cooling towers are used to remove heat from buildings. You can usually find large towers in places like power plants, petroleum refineries, and other manufacturing facilities.
Smaller ones often sit on the rooftops of universities, hospitals, and shopping centers. The most common application of cooling towers, however, is inside an HVAC (heating, ventilating, and air conditioning) system, disposing of unwanted heat from chillers.
Because of their various applications and the range of industries that use them, cooling towers vary in size and design. Their overall structure depends on the cooling load of the building. The relative humidity of the air also determines the size and type of cooling tower a building needs.
