Cooling towers have become an integral part of today’s cooling systems. Nearly all commercial and industrial buildings use a cooling tower for their HVAC systems. If you plan on starting a business, getting cooling tower for the facility will be an important step in many cases.
How Cooling Towers Work
Cooling tower systems are used to remove heat from a building using a cooled stream of water through the process of evaporation. They are used in many different industries such as power plants, manufacturing plants, and petroleum refineries, and are available in many different sizes, large to small, depending on their installation location.
They are most often used inside buildings for HVAC systems. The size and design of these towers will depend on the building’s cooling load. The larger the building and the more space that requires cooling, the larger the cooling tower will be. Humidity will also be a determining factor, but this is only affected by location. Areas with a warmer climate will likely be more humid.
Different Cooling Tower Types
Typically, cooling towers are classified by heat transfer methods, cooling tower build, and methods of airflow generation.
Builds include package type and field erection type. Package type units are pre-manufactured and are ready for implementation in any environment, while field erection type towers are often used in refineries or processing plants, and are larger than package type structures. Field erection type structures are customizable based on application.
Heat Transfer Methods
Heat transfer methods include both dry and wet cooling towers. Dry cooling towers will transfer heat while separating the cooling fluid from the surrounding air and don’t take in any water because they operate using an electric motor. Wet cooling towers, on the other hand, are the most affordable and renewable. They use water to keep the building cool.
Methods of Airflow Generation
There are four main types of airflow generation. Natural draft cooling towers use both the shape and overall design of the tower to move air upward through the use of fans and are normally located outside of a facility. Mechanical draft cooling towers contain a fan to move air, circulating it inside the tower, and they are smaller than natural draft units. Cross-flow cooling towers allow for horizontal air flow, with water traveling vertically, but are unfortunately difficult to maintain. Counter-flow towers make use of hot water that first enters through the top while air enters through the bottom and travels in the opposite direction.
These are the basics of cooling towers, and based on your facility, you’ll be able to benefit from the installation of the right type of tower. The best way to make sure that you get the most from your HVAC systems is to work with experts in the industry who have the experience and expertise to get the job done right. Professionals will be able to assist with tower selection and installation, along with all required maintenance.
