Sekoitusilmaa

Sekoitusilmaa, a Finnish term, translates to "mixed air" or "mixture air." It commonly refers to a blend of air that is not solely fresh outdoor air. This mixture can consist of recirculated indoor air and a certain proportion of fresh outdoor air. The primary purpose of using sekoitusilmaa in building ventilation systems is to control and optimize indoor air quality and thermal comfort while potentially reducing energy consumption.

In many HVAC (Heating, Ventilation, and Air Conditioning) systems, sekoitusilmaa is created by mixing air that has been returned from within the building with incoming outdoor air before it is conditioned (heated or cooled) and redistributed. The ratio of recirculated air to fresh air is a critical parameter that is often automatically controlled by the ventilation system based on factors such as the occupancy of the space, the detected levels of carbon dioxide or other pollutants, and the desired temperature.

Using sekoitusilmaa can offer several benefits. By recirculating indoor air, the system doesn't need to condition as much outdoor air, which can lead to significant energy savings, especially during extreme weather conditions. Recirculation also helps in maintaining a stable indoor temperature and humidity. However, it is crucial to ensure that the recirculated air is adequately filtered to remove dust, allergens, and other contaminants to maintain healthy indoor air quality. The balance between fresh air intake and recirculation is a key aspect of modern building design to achieve both energy efficiency and a healthy environment for occupants.
