A space cleaning system includes: a detection unit configured to detect generation and a generation position of an infectious substance in a space; an airflow control unit configured to generate an airflow towards the generation position detected in response to detection of the generation of the infectious substance; and a cleaning control unit configured to clean the space at least after the generation of the infectious substance is detected.

A structure for providing an indoor space includes an air-sterilizing apparatus configured to suction in air existing in the indoor space and to sterilize the suctioned air, a droplet blocking table configured to discharge the sterilized air in a direction toward a table top so as to allow the discharged air to be suctioned in along a central axis of the droplet blocking table, an air-conditioning apparatus configured to move the air suctioned in by the droplet blocking table, and an ordering apparatus configured to perform an order for a menu according to information input from a user.

A blower including a blowing unit that suctions and blows air, and at least one of a first venting member that has a first venting hole through which air blown from the blowing unit passes and that includes a coating film including a manganese oxide-based catalyst, activated carbon, a polyacrylate-based dispersant, and a resin, provided on a wall surface of the first venting hole, or a second venting member that has a second venting hole through which air suctioned into the blowing unit passes and that includes such a coating film provided on a wall surface of the second venting hole.

Body-worn air-treatment devices comprise a body that is configured to be selectively coupled proximate to a respiratory tract inlet of a living individual, and a pathogen-deactivating mechanism that is supported by the body. Methods comprise deactivating pathogens proximate to a respiratory tract inlet of a living individual.

An air decontamination apparatus for a common HVAC system includes a plurality of venturi holes. The plurality of venturi holes are configured to be positioned in the common HVAC system for forcing airflow in the common HVAC system through the plurality of venturi holes. Each of the plurality of venturi holes including an antimicrobial coating. Wherein, the air decontamination apparatus is configured to kill bacteria and viruses in the airflow in the common HVAC system via the antimicrobial coating on each of the plurality of venturi holes.

A system includes one or more occupancy sensors, one or more environmental sensors and one or more controllable building components. A controller is configured to receive occupancy signals from the one or more occupancy sensors over a building network and to receive indoor air quality parameter signals from the one or more environmental sensors over the building network and to process the received signals to determine whether action is needed to improve one or more environmental conditions within at least some of the plurality of building spaces to reduce the likelihood of disease transmission among occupants of the building. Responsive to determining that action is needed, the controller is configured to provide control signals to one or more of the controllable building components over the building network to improve one or more environmental conditions within at least some of the plurality of building spaces.

The present disclosure relates to a smart tunnel having a tunnel structure having a quarantine section and a disinfection section, which is capable of regularly performing a quarantine function for determining whether an infectious disease is introduced and a disinfection function for preventing spread of an infectious disease.

An air conditioner is disclosed. The air conditioner comprises a storage, and a processor for identifying a target space on the basis of first gas sensing data, moving the air conditioner to the target space, acquiring information about a gas type on the basis of second gas sensing data sensed within the target space and reference data stored in the storage, and performing an air conditioning operation on the basis of the information about the gas type, wherein the gas sensing data is sensed by a sensor comprising a plurality of sensing modules that react to different gases.
