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.

A self-disinfecting antiviral filter material 10 includes an air-permeable carrier 11 and a composite coating 12 including at least one color pigment 13 with antiviral activity and an inorganic matrix material 14 bonded to the carrier 11. The at least one color pigment 13 preferably includes at least one compound from the group of phthalocyanines. The matrix material is preferably selected from the group including metal oxides. An air filter device including the self-disinfecting antiviral filter material, a method of manufacturing the filter material, and a method of inactivating viruses are also described.

Vent apparatuses comprise a filter comprising a pleasant scent such that when forced air passes therethrough, the scent on the filter is distributed into the room. Alternatively, a tank and/or reservoir may be disposed adjacent the vent, whereby upon activation a spray of a scent may be introduced into the airstream of the forced air and thereby distributed around the room, or the spray may be forced onto the filter, which may act as a substrate holding the scent thereon such that when forced air passes therethrough. In an alternative embodiment, the vent comprises fan blades that generate electricity from the forced air flowing therethrough for powering electronic devices and/or for charging batteries.

An air treatment device having a flexible air hose, duct or gooseneck member. The air hose, duct or gooseneck member permits an inlet end thereof to be positioned in proximity to a patient so that a negative pressure can be created around the patient so that air can sucked or vacuumed into the system whereupon it is treated as the air flows through the system.

The present invention relates to an air conditioning device. The air conditioning device sucks air through a suction portion and sending the sucked air to a blowing portion to perform air conditioning, wherein the suction portion includes a virus killing portion formed of a fiber to which copper ions are bonded and killing a virus, the virus killing portion includes a caz fabric configured to contain 5 to 50 wt % of an antiviral alginic acid conjugate fiber configured so that the copper ions are contained in an amount of 6,000 to 100,000 ppm in a fiber, and the virus killing portion has a differential pressure exceeding 0 Pa and less than 10 Pa.

An air purifier and conditioner (and concomitant method of simultaneously purifying and conditioning air) comprising a housing receiving source air and an aqueous solution, a drop charger receiving the source air and providing a spray of electrically charged drops of the aqueous solution to produce treated air, a mist eliminator eliminating liquid in the treated air and producing conditioned air, a heat exchanger receiving the conditioned air and producing supply air, and a fan moving the supply air to a facility employing the supply air.

An air cleaning apparatus includes: a collection filter for collecting dust; a first ultraviolet light emitter for irradiating the collection filter with ultraviolet light having a first wavelength; and a photocatalyst supporting filter which supports a photocatalyst exhibiting photocatalytic activity by the ultraviolet light having the first wavelength and collects the dust. The collection filter transmits the ultraviolet light having the first wavelength, and the ultraviolet light having the first wavelength passing through the collection filter is irradiated to the photocatalyst supporting filter.

System and method to reduce risk of patient infections (HAI), using operating rooms (chambers) equipped with suitable automatic airborne sterilizing agent generators, sensors, mechanisms, automatic air control devices, and laminar flow devices. After suitable safety checks, the system isolates the interior air from external air, and activates an air phase anti-microbial agent generator, filling the room with an air-phase anti-microbial agent. After sterilization, the invention deactivates the generator then restores the connection to outside sterilized air. The chamber also comprises an intelligent platform comprising video cameras, and computer vision systems configured to identify humans and medical supplies, read optical tags, and correlate recognized objects with RFID tag data. The intelligent platform can be configured to automatically detect and warn on conditions associated with a high risk of HAI, optimize the sterility of the chamber, automatically detect other operating room issues, and interface with outside computerized medical databases and facilities networks.

A HVAC air treatment (HAT) system/method for use in heating, ventilation, and air conditioning (HVAC) systems that incorporates an air flow sensor (AFS), timer control unit (TCU), ultraviolet lamp(s) (UVL), lamp feedback indicator (LFI), liquid distribution atomizer (LDA), leak exhaust fan (LEF), and digital control processor (DCP) is disclosed. The AFS indicates detection of air flow within the HVAC ducts (HVD) to the DCP and may wirelessly communicate with the DCP. The DCP interrogates the TCU to determine when HAT is to occur if HVD air flow is detected and activates the UVL to disinfect air within the HVD. The LFI provides feedback to the DCP to verify that the UVL is operational. The UVL may be positioned at the fresh air intake (FAI), air intake plenum (AIP), evaporator/heat exchanger (HEX), and/or air exhaust plenum (AEP) and may incorporate an adjustable magnetic frame (AMF) allowing UVL retrofit installation.
