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). The regulating unit ascertains, through a non-use indicator fuse, whether or not the container is new or previously used and prohibits start of operation should a used container be installed.
