Abstract (en)

[origin: EP0003970A1] 1. Process for ventilating rooms, in which the air flow is conveyed through a duct provided with opening cross-sections of varying sizes at both ends and having an expansion chamber in the area between its ends, characterized by the fact that the pressure level of the air flow is suddenly lowered (3, 7 or 7, 5) when it flows into the expansion chamber (5) and is then suddendly raised again (5, 7 or 5, 3) before emerging from this expansion chamber (5), and that the air flow is diverted or rerouted between the lowering of the pressure (3, 5 or 7, 5) and the rise in pressure (5, 7 or 5, 3).
