A first recirculation air supply line (14) is adapted to supply recirculation air to the mixing device (10).

The recycle-to-air vent ratio is controlled by a processor (78) which adjusts the recycle flow (52) based on the ambient temperature and the power level of the fuel cell (12).

A demister (39) removes moisture from recycled air entering the air pump (18).

What’s known as the “bleed air” system combines recirculated and fresh breathable air.

The process involves fresh air supply as well as purification of recycled air.

An air mixer (10), with a water collector (46), is disclosed for supplying recirculated cabin air in aircraft.

A device (D) is intended to control the position of a supply shutter (V1) controlling the supply of outside and/or recycled air of a heating/air conditioning installation (IC) intended to supply an enclosure with treated air.

It’s not recycled air riddled with the germs of everyone on board.

When outside air or recycled air is found to be polluted, the recommended control measures consist of filtering it and cleaning it.

New aircraft use recirculated cabin air to a much greater degree than do older models.

The device is provided with an additional intake channel (4), for the transfer of the recycled air and a chamber (14) for mixing the recycled air with the outside air.

Separation must thus be physical and, if the air-conditioning system uses recycled air, the air from smoking areas should not be mixed with that from non-smoking areas.

Astronauts spend months in the same quarters, breathe recycled air and drink recycled water; conditions that create a bacterial breeding ground.

The C5H8 Collection messenger bag, made of recycled inner tubes and recycled black vegetal leather, is truly unique.
