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).

Abstract: The present invention relates to a hot-air supply system for an aircraft equipped with at least one engine (2) with a fan (3) and compressors (4). According to the invention, the regulating devices (14, 15, 16) intended to regulate the flows of hot air and of cold air sent by the pipes (10 and 11) to the heat exchanger (12) are pneumatic, controlled electrically, and are controlled by a centralized management device (24).
