A method for purifying air within a space is provided. The method includes a controller determining whether an ON signal is received. Upon determining that the ON signal is received, the controller instructs an air sanitizer of an air sanitization system to turn ON to purify an airflow passing through the air sanitization system, and instructs an air movement fan/blower to operate in order to direct the airflow into the space. Upon determining that the ON signal is not received, the controller instructs the air movement fan/blower and the air sanitizer to be OFF.

To provide a method for disinfecting air and surfaces which provides a continuous protection of people and/or animals from pathogens a given volume, in particular for essentially 24 hours a day, and which can be conducted with people and animals present, a method for disinfecting air and surfaces is proposed, wherein a disinfectant is dispersed into a volume to be disinfected, wherein the disinfectant comprises electrolyzed and/or sterilized water containing hypochlorous acid, and wherein a dispersion rate of the disinfectant is adjusted such, that a concentration of the hypochlorous acid in the volume is continuously between 0.05 mg/m.sup.3 and 10.0 mg/m.sup.3.

An improved high-efficiency electrostatic air filter device implements a dust collection function and incorporates a material that captures and that is toxic to viruses/bacteria and causes viruses and bacteria to be rendered harmless by contact with this material. The device is composed of a charging section having a conductive antiviral media to charge any particles in the gas with a high electric voltage and a collecting section which contains or is composed of conductive material which has antiviral/antibacterial properties and a surface of opposite polarity or lower potential that will cause the aforementioned charged particles to adhere to the toxic material as the gas flows through or around the media. The collection section is formed with or coated by an inactivating material that inactivated pathogens when physically contacted.

An air conditioning apparatus includes an air vacuum pump that sucks in air from a prescribed space to place the space under negative pressure, a first hot and cool air tank that contains the sucked air, first valves that adjust the flow rate of air supplied to or discharged from the first hot and cool air tank, a second hot and cool air tank that contains the sucked air while an air flow from the air vacuum pump to the first hot and cool air tank is restricted, second valves that adjust the flow rate of air supplied to or discharged from the second hot and cool air tank, and a heating and cooling device that manages the temperature of at least one of the first and second hot and cool air tanks to which an air flow from the air vacuum pump is restricted.

A hygiene management device for an entrance hall includes a fan assembly which generates an air blowing force, a function module which provides a storage space, an air discharger which discharges air toward a person, and an opening/closing unit which selectively stops an air flow. Particularly, the opening/closing unit is configured such that air is supplied into at least one of the function module and a duct unit or simultaneously into both the function module and the duct unit.

The invention relates in particular to an apparatus (100) for disinfecting at least one room, in particular for one or more persons, preferably a dwelling space or treatment room, for example a treatment room in a building, in particular a sickroom, a patient room and/or an operating theatre, by means of an atomiser. Specifically, the apparatus (100) is characterised in that the atomiser includes a rotatable bell cup (1) for atomising a disinfectant into the room. The invention relates to an associated method and furthermore to the use of a bell cup (1) for atomising a disinfectant in a room for, in particular, one or more persons.

An indoor air quality (IAQ) control system for a heating, ventilation, air conditioning, and Refrigeration (HVACR) system including an IAQ monitor that collects air quality data from an air quality sensor of an air quality-controlled space; a controller that manages a remediation device of the air quality-controlled space; and an IAQ management server that generates a biological pollutant estimate based on the air quality data using an algorithm that correlates the air quality data to the biological pollutant estimate, and generates a remediation recommendation. Additionally, a control method includes collecting air quality data from an air quality sensor of an air quality-controlled space using an IAQ monitor; managing a remediation device of the air quality-controlled space using a controller; generating a biological pollutant estimate based on the air quality data using an algorithm that correlates the air quality data to the biological pollutant estimate; and generating a remediation recommendation.

This invention relates to a combination of machinery, electronics and building space design using specialized disinfection systems, air filtration, audio-visual communication, electronic controllers and isolation booths in a manner that mitigates the risk of disease transmission among simultaneous and serial users of the shared space.
