AIR VENTILATION
Conditioned air is blown into the cabin by outlet ramps located under the hot racks
through two electrical isolating valves (CAB VENT).
It is then evacuated through guides along the cabin side walls at floor level. A part of
it is recirculated by the fans, the other part being evacuated overboard through the
outflow valves installed in the rear under floor.
The toilet is ventilated by differential pressure through a vent line.
