How Cooling Towers Help Businesses Run Smoothly



As concentration increases; various minerals, including calcium carbonate, tend to form crystals on the heat transfer surface, ultimately reducing the efficiency of the equipment. This means that the accumulation of minerals in the water can create layers that reduce efficiency. These deposits can become so abundant in cooling systems that they impede the free flow of water and air, weigh down the structural elements of the cooling towers and can potentially cause them to collapse. Corrosion, white rust and even pool failure can occur if impurity deposits are not maintained and the pool water is allowed to sludge. 

Water treatment, along with chiller and cooling tower maintenance, which includes cleaning all heat transfer surfaces, is a way to keep your commercial HVAC system running smoothly. An appropriate cooling tower water treatment program can maximize system efficiency as well as extend equipment life through the use of cooling water. Water treatment options such as simulated water, environmentally friendly chemicals, filtration and softening ensure that your cooling tower is performing optimally and meeting the required cooling requirements. These procedures can prevent loss of efficiency in the heat transfer section by maintaining adequate water and air flow and preventing corrosion in the cooling tower. 

The frequency of maintenance depends on the type of tower, its size and external factors such as the geographic location of the building. Regular preventive maintenance can also help conserve water, extend the life of your cooling equipment, and reduce energy and equipment costs. With the rise in energy prices and the focus on the environment, it is important to design, build, install and maintain cooling towers so that they use less energy. 

Water-cooled and open-loop systems consume less energy than air-cooled systems. Liquid-cooled chillers are generally more energy-efficient than air-cooled chillers because they dissipate heat in the cooling tower water at or close to the wet bulb temperature. 

Cooling towers can use the evaporation of water to remove process heat and cool the process fluid to air wet bulb temperature, or in the case of closed-circuit cooling towers or cooling towers, only rely on air to cool the process fluid to air dry bulb temperature. Use a radiator. The main application of large industrial cooling towers is to remove power plants, oil refineries, petrochemical plants, natural gas processing plants, food processing plants, semiconductor plants and other structures such as condensers, distillation towers, and coolant used in the crystallization process. Cooling towers, especially HVAC cooling towers, are a water circulation system that reduces water consumption, saves energy, and reduces operating and operating costs. In the final analysis, it is a heat sink that uses evaporative cooling to transfer waste heat from the atmosphere. Failure to maintain the cooling tower can cause leaks and water accumulation, which can attract mosquitoes. 

Due to the temperature of the hot water, if the cooling tower water is not properly maintained through chemical treatment, it may contain harmful bacteria, such as Legionella. If the water supply is not properly maintained, it may cause Legionnaires’ disease. When air, sodium, and other chemicals in our water system pass through the cooling tower system without testing, they can absorb metal and cause leakage. Fouling is the clogging of cooling surfaces or pipes with debris, dirt and dust. When water cannot enter and pass through the filling as expected, the air is not properly cooled.

Taking all these factors into account in the operation of the on-site cooling towers can help businesses operate smoothly.
