Method and device for disinfecting and cleaning enclosed spaces in particular, such as a passenger compartment on a means of transport

A method for disinfecting and purifying to prevent contamination of transport vehicle including an engine, a compressor, and a passenger reception area equipped with a ventilation air circuit, contamination by aerosols, microdroplets, bacteria or viruses, the method comprising:

• installing, in the ventilation circuit of the passenger reception area, at least one capacitor filter with porous armatures and dielectric, impregnated or not with bactericidal or virucidal substances that cannot be released into the ventilation air circuit of the passenger reception area, the at least one capacitor filter being connected to the positive and negative poles of an electricity generator;
• creating a swirling vortex of aerosols and microdroplets of a disinfectant liquid or aerosols or microdroplets of a disinfectant liquid by a driving gas;
• bringing the aerosols or the microdroplets of disinfectant liquid into contact with aerosols and microdroplets likely to contain bacteria and viruses by spraying the created swirling vortex mixture on clothing and luggage of passengers before the passengers enter the passenger reception area;
• bringing the aerosols or microdroplets of disinfectant liquid into contact with the aerosols and microdroplets likely to contain bacteria and viruses by spraying the created swirling vortex mixture one or more of:
• (i) on solid surfaces and (ii) in the air of the passenger reception area to be disinfected;
• and
• spraying the created mixture on the engine of the aircraft and on the compressor to wash the aircraft.
