Märgjahutuskolonni

Märgjahutuskolonn, also known as a wet cooling tower, is a device used to reduce the temperature of water through direct contact with air. This process, called evaporative cooling, relies on the principle that as water evaporates, it absorbs heat from the remaining liquid, thereby lowering its temperature. In a typical märgjahutuskolonn, hot water is pumped to the top and then distributed over a material designed to increase surface area, often referred to as fill. As the water flows down through the fill, ambient air is drawn or forced through the structure. This airflow facilitates evaporation, and the cooled water is collected at the bottom of the tower.

The primary function of a märgjahutuskolonn is to dissipate waste heat from industrial processes or HVAC systems into the atmosphere. They are widely employed in power plants, chemical processing facilities, and large buildings. The efficiency of a märgjahutuskolonn is influenced by factors such as air humidity, temperature, and airflow rate. While effective, these towers can lead to water loss through evaporation, drift, and blowdown, necessitating a continuous supply of makeup water. Maintenance is also crucial to prevent issues like scale formation, biological growth, and corrosion, which can impede performance and longevity.
