METHOD FOR DISINFECTING A VENTILATION NETWORK AND DEVICE FOR SAME

摘要

The invention relates to a method for disinfecting the inner walls of a ventilation network (104) without using any chemical other than ozone. The invention is characterised in that the method comprises: the step of generating a biocidal ionised gas essentially comprising ozone; the step of injecting the biocidal ionised gas into said network; and the step of condensing the biocidal ionised gas on the inner walls of the network; the device includes a generator (65, 102) for generating a biocidal ionised gas substantially comprising ozone, characterised in that the device further comprises a means (106) for injecting the biocidal ionised gas into the ventilation network.
