ilmanvaihtolämmitys
Ilmanvaihtolämmitys is a Finnish term referring to a heating system that utilizes ventilation air. In this system, the fresh air brought into a building for ventilation purposes is also used as a medium for heating. This means that the incoming outdoor air is preheated before being distributed throughout the building. The primary purpose is to provide both ventilation and heating simultaneously using the same air stream.
The concept relies on recovering heat from exhaust air or using a separate heat source to warm
Ilmanvaihtolämmitys systems are often integrated into mechanical ventilation units, commonly found in modern residential and commercial
