avdunstningen

Avdunstningen is a Swedish term describing the process of removing or reducing mist, haze, or condensation from a surface or space. The word is composed of av- (off, away) and dunst (mist, fog) and is used in both everyday language and technical discourse to denote demisting or defogging.

In everyday use, avdunstningen often refers to clearing moisture from windows, windshields, or mirrors, enabling better visibility. In technical and industrial contexts, the term covers a range of technologies and methods designed to prevent or reverse condensation on surfaces. This includes anti-fog coatings, lens heaters, and ventilation strategies that keep surfaces dry and transparent.

In automotive applications, avdunstningen typically involves systems that blow warm or dry air onto the interior surface of the windshield to prevent or remove fog. In buildings and laboratories, it relates to dehumidification and controlled ventilation that reduce humidity and suppress condensation on glass walls, mirrors, or equipment.

In meteorology, avdunstningen can describe the atmospheric process by which fog or mist dissipates, often as a consequence of rising air temperatures, solar heating, increased wind, or turbulent mixing that lowers relative humidity near the surface.

Common methods to achieve avdunstningen include heating, targeted airflow, dehumidification, and surface treatments such as anti-fog or hydrophilic coatings. See also demisting, defogging, and dehumidification.
