haihdutusjäähdytin

haihdutusjäähdytin is a Finnish term that translates to evaporative cooler in English. It is a device that cools air through the evaporation of water. Unlike air conditioners which use refrigerants and a compressor, evaporative coolers rely on a natural process.

The basic principle of operation involves drawing warm, dry air through a wet pad or cooling medium. As the water evaporates from the pad, it absorbs heat from the air, thereby lowering the air's temperature. The now cooler, more humid air is then blown into the space. This process is most effective in dry climates where the humidity is low, as high humidity reduces the rate of evaporation and thus the cooling potential.

Evaporative coolers are generally more energy-efficient than traditional air conditioners and do not release harmful refrigerants into the atmosphere. They also add moisture to the air, which can be beneficial in arid environments. However, their cooling capacity is limited, and they are not suitable for very humid conditions. They are commonly used in homes, workshops, and outdoor spaces where a more natural and less energy-intensive cooling solution is desired. The water is typically supplied from a reservoir that needs to be refilled periodically.
