The two airflows (internal/external) are totally separated. The external air is only used to
cool down the internal air via the counter flow recuperator. The air flows are never
mixed.
The warm internal air is sucked from the base station into the internal fan at the top of
the HEX 6 A and let through the recuperator, where it is cooled down.
After the cooling in the recuperator the air is let back into the base station.
The cold external air is sucked into the external fan at the bottom of the HEX 6 A and
let through the recuperator, where it is cooling down the internal air.
After having passed through the recuperator the air is let back to the external
environment at the top of the unit.
