A cooling tower is a heat removal device that uses water to transfer process, waste heat into the atmosphere. Likewise, an industrial cooling tower operates on the principle of removing heat from water by evaporating a small portion of water that is recirculated through the unit. The mixing of warm water and cooler air releases latent heat of vaporization, causing the water to cool. If you are ever looking down from a high-rise building, you might notice square units with fans on top of them on the buildings below. Those are water cooling towers. No one wants to stay in a building with bad air conditioning—at least not for too long. On the other hand, buildings with excellent cooling make you want to return, even if it’s just to enjoy the air. That’s thanks, in large part, to the continued modernization and innovation of the commercial cooling tower system. What Is The Purpose Of A Cooling Tower? A water cooling tower is used to cool water and is a huge heat exchanger, expelling building heat into the atmosphere and returning colder water to the chiller. A water cooling tower receives warm water from a chiller. This warm water is known as condenser water because it gets heat in the condenser of the chiller. The chiller is typically at a lower level, like in a basement. The cooling tower’s role is to cool down the water, so it can return to the chiller to pick up more heat. Types Of Cooling Towers what is an industrial cooling tower?Cooling towers systems are often vital to industrial processes. These tall, open-topped, cylindrical structures are responsible for cooling water generated from industrial or HVAC comfort cooling airflow. They are classified by the type of draft (natural or mechanical) and by the direction of airflow (counter or cross). Natural Draft Cooling Tower Systems are usually used for large power plants and industries with infinite cooling water flow. The tower operates by removing waste heat by way of rising hot air that is then released into the atmosphere. These towers are tall and have a hyperbolic shape to induce proper airflow. Mechanical Draft Cooling Tower Systems have air forced through the structure by a fan that circulates air through the tower. Common fans used in these towers include propeller fans and centrifugal fans. While Mechanical draft towers are more effective than natural draft towers, they consume more power and cost more to operate as a result. Crossflow Cooling Tower Systems have a design that allows the air to flow horizontally through the fill and the tower’s structure into an open plenum area. Hot water flows downward from distribution basins. However, fans and motor drive require weather-proofing against moisture which can lead to freezing making it less efficient. Counterflow Cooling Tower Systems have a design where the air moves upwards and the counter-current, with hot water, falls downward to cool the air. This allows for maximum performance out of each plan area and helps minimize pump head requirements. Also, a counterflow cooling tower system is less likely to ice up in cold weather conditions and can save energy in the long run. All Delta Cooling Towers are counterflow with these advantages. Induced Draft Cooling Tower Systems of DAMATAJHIZ are typically mounted with a fan at the top of the cooling tower, which allows hot air out and pulls air throughout. The high exiting air velocities reduce the chance of re-circulation. To avoid the entrapment of water droplets in the leaving stream air, drift eliminators are used. Induced draft towers are more efficient as they use 30% to up to 75% less energy compared to forced draft designs. Forced Draft Cooling Tower Systems This cooling tower system is similar to induced draft, but the basic difference is that the air moving fan is placed at the base of the cooling tower, which allows the air to blow through from the bottom. Their use is limited due to water distribution challenges, high horsepower fans, and the possibility of re-circulation.
