märgjahutuskolonn

Märgjahutuskolonn, also known as a wet cooling tower, is a heat exchange device used to dissipate waste heat into the atmosphere. It functions by bringing water into direct contact with air, causing a portion of the water to evaporate. This evaporation process absorbs a significant amount of heat from the remaining water, thereby cooling it. The cooled water can then be recirculated to absorb more heat from a process or system.

The primary components of a typical märgjahutuskolonn include a basin to collect the cooled water, a fill material to increase the surface area between water and air, a fan to induce airflow, and spray nozzles to distribute the hot water. As hot water is pumped to the top and sprayed downwards over the fill, air is drawn or forced through the fill. The contact between the water and air facilitates evaporation, which is the main cooling mechanism. The cooled water collects in the basin at the bottom, while the warmed, humidified air is discharged at the top.

Märgjahutuskolonns are widely used in industrial applications such as power plants, chemical processing plants, and refrigeration systems, as well as in large commercial buildings for air conditioning. Their efficiency is dependent on factors like ambient air temperature, humidity, and airflow rate. While effective, they do require a supply of make-up water to compensate for evaporation, drift, and blowdown losses, and may also require water treatment to prevent scaling and biological growth.
