10. Technical information

10.1 Operating principle

The operating principle of air-air heat ex-
changers is based on the transfer of heat
between two air flows with different temper-
atures through a surface featuring a high
heat transfer coefficient (figure F.06) which
separates the two environments to avoid
the transfer of dirt and contaminants from
the exterior to the interior environment.
