In most cases, cooling towers are used in areas where standard HVAC systems are not a viable solution, including power plants, oil refineries, petrochemical plants, natural gas processing plants, food processing plants and other large-scale industrial plants. Generally, a cooling tower contains a wet deck with air intakes, air outlets, connectors, intake pipes, cooling water basins, filling rooms, mechanical instrumentation, fans, propellant separators and shells. Oil refineries and chemical cleaning plants, steel mills, food and drink production plants, nuclear power plants and petrochemical plants produce high temperatures for a certain amount of waste heat that requires large or small cooling towers.
Evaporative heat recovery devices such as cooling towers provide a lower water temperature than air-cooled or dry heat recovery devices to achieve a cost-effective and energy-efficient cooling system. Clean evaporative cooling towers mean that evaporative cooling towers are highly efficient and can provide maximum efficiency and minimum power consumption by evaporating and flushing the water. The category of Evaporative Heat Rejection equipment includes cooling towers used in various applications such as power plants and HVAC production, which are a cost-effective and energy-efficient means of generating heat from various industrial processes and cooling large buildings and plants.
As part of the cooling tower water process a water treatment plant is required that removes the hardness of silica and stabilizes the pH and adjusts the value. In this way, liquid and solid waste concentrates can be removed and the treated water returned to the tower for reuse. As part of the cooling process, the correct treatment optimizes the evaporation cycle of the towers, minimizes the water ventilation rate and drains without chemicals.
The open circulation cooling system saves an enormous amount of fresh water compared to alternative cooling methods. The amount of water discharged as waste is greatly reduced, while alternative methods of cooling and chemical treatment are less economical.
An example of a customised solution for industrial cooling towers is that of a chemical program which is used to reduce problems with industrial cooling and water systems. The cooling tower unit is built with state-of-the-art technology and is housed in a robust frame that allows quick access to the central components, enabling maintenance and routine maintenance.
Free cooling systems allow towers to meet the cooling needs of buildings without having to work as coolers in cold weather. The most visible feature of the open circulation cooling system is a large outdoor cooling tower, which releases heat and cool water through evaporation.
For example, if your system works well with evaporative cooling, ASME and CTI recommend measuring the effectiveness of your towers using wet bulb temperatures. This information makes it possible to determine the exact parameters of the wet bulb temperature. This, as we have seen, defines how bad the environmental conditions are during the installation and what minimum temperature is likely to reach a water-cooled evaporation tower. There are certain types of free cooling systems and certain elements that need to be in place for a free cooling system to be considered.
