roottorilämmönvaihtimet
Root-and-rotor heat exchangers, known in Finnish as roottorilämmönvaihtimet, are a type of rotary heat exchanger used in applications such as heat recovery in ventilation systems. They consist of a rotor that rotates slowly within a housing. The rotor is typically made of a material with high thermal conductivity, such as aluminum or a ceramic.
As warm exhaust air passes through one half of the rotating rotor, it heats up the rotor
The primary advantage of roottorilämmönvaihtimet is their high efficiency in recovering heat, often exceeding 80%. They
