Abstract: Described is an anti-condensation method for an aircraft (13), wherein part of a stream of cold air is withdrawn, the part of a stream of cold air is heated, and the part of the stream of hot air is introduced into the crown (19) of the aircraft (13) through an air introduction duct (8). Also described is an anti-condensation device called “Air Dryer System”.

Abstract: A process and apparatus for humidification of air in a cabin (4) of an aircraft, wherein a secondary flow of warm air is taken from a primary warm air flow that originates in a turbomachine of the aircraft. This secondary warm air flow is introduced into a boiler (6) enclosing an air/water heat exchanger (17) and at least partially filled with water, so as to form in said boiler a flow of water vapor as a function of the secondary warm air flow. At the outlet of the boiler (6) the flow of water vapor and the flow of secondary warm air are in mixed together and injected into the heating/air conditioning circuit for the air in the cabin (4).
