Abstract: This invention concerns a steam generator (100) intended to humidify the air in an enclosed space or the air treated in an air conditioning system, particularly an air conditioning system aboard an aircraft, said steam generator (100) comprising at least one tank (110) intended to contain a water-based fluid (E), said or each tank (110) being connected to a heat exchanger (210) intended to convert the fluid (E) into steam. The steam generator (100) is remarkable in that the heat source connected to the heat exchanger (210) is a thermochemical reactor (230).

Abstract: A fabric sheath (1) for the close protection of the conveyance of sensitive products by sterilized air stream diffusion, in particular in a substantially vertical direction is formed by a sealed wall (2) and a porous wall (3) extending longitudinally and axially along the sheath, the sheath defining a sterilized air supply duct (9). It comprises means (4) extending longitudinally along the sheath that ensure median sterilized air diffusion at a higher speed. The invention also features a washable or disposable laminar-flow hood, comprising a fabric sheath bounded at each end by a plane perpendicular to the axis of the fabric sheath.

Abstract: The invention relates to a steam generator for humidifying an airplane air conditioning system. The steam is generated in a container (21). A support (50) enables a translational movement of a tubular part (49) connectable to a duct of a humidifier along the main axis of the container (21) in order to connect it with the outlet opening (24) of the container (21). Inside container (21), there are at least two electrodes (31, 32, 33) that are partially immersed in water and which are energized under a constant voltage up to a certain level of current in electrodes (31, 32, 33). Also, container (21) includes a fuse 38 with one end connected to a first of the terminals, the other end of the fuse being of the connected to one of the electrodes (31, 32, 33). A regulating unit (60) measures and maintains the intensity that current passing through electrodes (31, 32, 33). At the time of the installation of a new container, the regulating unit (60) determines whether the fuse (38) is or is not conductive.

Abstract: A steam generator for the humidifier of an air conditioning system, especially an aircraft air conditioner system, is connected by a duct to a dilution cone located inside an air flow duct (4) of the humidifier. A container (21) has an opening (22) for enabling an exiting of the steam developed inside said container (21). The opening (22) is connected to the humidifier duct (4). An opening (23) for the filling with water, is connected to the outlet of a feed valve (48), the intake opening of which may be connected to a source for the supply of water. Inside the container (21), an electric resistor (30) is completely immersed in the water. A regulating unit (60) receives signals delivered by a hygrometer (9) and that governs the intensity of current passing through the resistor (30). The regulating unit (60) causing the intensity of the current in resistance (30) to be dependent on the value of the signals delivered by the hygrometer (9).

Abstract: An aircraft air conditioning system circulates hot air to a humidifier having an atomized or vaporized water generator (2, 35). The exit of the water generator is located at the apex of a conical surface (20, 27, 42) which diverges in the direction of air circulation. The conical surface is pierced by holes (21) through which the hot air passes while encountering and mixing with the water particles or the water vapor mixes them there and carries them along. The conical surface is a surface of revolution (27) opening downstream. The apex of the conical surface is practically in the form of a spherical cap. The center of the apex is pierced by an outlet passage of the generator (2, 35).
