It is also known from practice that with portable cleaning devices, objects or people can be decontaminated in one place which contamination occurs or on which temporary decontamination is to be carried out.
  • Standardized clean room classes are known, the air purity classification being subdivided for individual particle size ranges on the basis of the particle concentrations. Since in many cases a clean room is mainly contaminated by people entering the room and staying in the room, many clean rooms are designed so that the number of people staying in them is kept as low as possible and, in particular, the frequency is minimized as much as possible , with which individual persons enter or leave the clean room.
  • decontamination measures developed and designed accordingly for such clean rooms are not necessarily suitable for rooms with changing public traffic. Nevertheless, it can be advantageous to continuously carry out decontamination measures in a room within a building that is used by several or many people in order to keep the risk of contamination of individual persons who are in the room as low as possible.
  • this object is achieved in that, in a planning acquisition step, several usage areas within the room are based on a predetermined usage concept and an expected intensity of use is determined for each area of use on the basis of previously determined parameters, and in a subsequent planning implementation step for each area of use, based on the intensity of use, a suction device assigned to this area of use with an assigned suction volume flow is specified.
  • An essential aspect of the method according to the invention is the division of the room into different usage areas, which is individually adapted to a usage concept of the room. The correspondingly divided space then has several usage areas and one or, if necessary, several non-usage areas that are separate from one another.
  • an intensity of use that is likely to occur when the room is used as intended is determined by people who are in the area of use in question.

While the larger droplets from the exhaled air flow sink rapidly downwards and are deposited on surfaces located there, small droplets in particular remain in the exhaled air flow for a long time and can be distributed as suspended particles in the environment.
  • the suction power can be determined for each area of use, based on the assigned intensity of use, which is required to suck the aerosols exhaled by the people in the area of use as comprehensively as possible from the area of use and thereby prevent them, that exhaled aerosols can spread to neighboring areas of use.
  • a single suction device may be assigned to several separate usage areas within the room. In this case, it is not considered necessary, but advantageous if the suction device has at least one suction opening for each area of use, through which a portion of the suction volume flow generated by the suction device can be sucked in.
  • the assignment of a single suction device to several areas of use is particularly advantageous when the areas of use are of a comparable intensity of use.

  • Non-usage area is required.
  • the extraction of air from the usage areas forces air to circulate within the room, so that air from the non-usage area can also flow into a usage area and is extracted there.
  • a suction device is additionally provided at a suitable point within the room, which, in addition to the individual suction devices in the areas of use, removes air from the room Vacuuming the non-use area.
  • the extraction of room air from the non-use area is operated with a lower suction power or with a lower suction volume flow than with the extraction from the usage areas in order not to impair the targeted extraction of air from the usage areas.
  • an air supply device assigned to this use area with an assigned supply air volume flow is specified for each usage area based on the expected usage intensity.
