Korvausilmayksikkö

Korvausilmayksikkö, meaning "replacement air unit" in Finnish, is a ventilation component commonly found in buildings. Its primary function is to supply fresh, outdoor air into interior spaces, thereby compensating for the air that is extracted by exhaust systems or lost through infiltration. This process is crucial for maintaining good indoor air quality and preventing issues such as humidity buildup, stale air, and the accumulation of pollutants.

These units can take various forms, from simple passive vents to more complex mechanical systems. Passive korvausilmayksikkö typically rely on natural pressure differences to draw in outside air, often through grilles or openings in walls or windows. Mechanical units, on the other hand, employ fans to actively draw in and distribute fresh air. Some advanced systems may also incorporate filters to remove dust and other particles from the incoming air, and even heating or cooling elements to temper the air before it enters the building, contributing to both comfort and energy efficiency. The presence and type of korvausilmayksikkö are determined by building design, local climate, and specific ventilation requirements.
