ABSTRACT:
The invention relates to a device and a method for the generation of respirational air. The device according to the invention makes it possible to dehumidify air optimally. The dehumidification problem is achieved with a tapering passage, in particular with a nozzle. The nozzle is contained in a tube in which the mixture of air and water flows. A pressure which is higher on one side and which leads to a local increase in the flow rate in the nozzle and to a lower temperature prevails in the nozzle. These circumstances result in the water further condensing out of the air in the nozzle. The water which is condensed out is entrained by the air stream and can be separated off in a water separator connected directly after the nozzle, even before the gas or the air (after the nozzle) can become saturated again.
