SEMI-OPEN DEVICE FOR AIR DISINFECTION IN AN AIR-CONDITIONED ROOM Russian patent published in 2021 - IPC A61L9/00 

FIELD: ventilation systems and air disinfection.

SUBSTANCE: invention relates to the field of ventilation systems and air disinfection. A semi-open device for air disinfection in an air-conditioned room for joint operation with a split-room system contains a section that emits ultraviolet radiation by means of at least one built-in source of ultraviolet radiation. The section, which emits ultraviolet radiation, contains an inlet air flow sensor to determine the speed of the incoming air flow when the split system is turned on. The section also includes a device for controlling UV sources connected with UV radiation sources.The section, which emits ultraviolet radiation, is made of material that blocks ultraviolet radiation and is made open along the axis of movement of the inlet air flow into the split-system of the conditioned room. A screen is attached to the section emitting ultraviolet radiation which directs the output air flow to the upper part of the room and in which additional sources of ultraviolet radiation and an output air flow sensor are installed to determine the speed of the incoming air flow when the split system is turned on. A control device for additional sources of ultraviolet radiation is also a part of the screen. The screen is made of material that blocks ultraviolet radiation. The section, which emits ultraviolet radiation, and the screen have design capabilities that allow you to change their dimensions in accordance with the dimensions of the split system of the air-conditioned room installed between them.

EFFECT: invention makes it possible to safely use room-type air conditioners in confined spaces from the point of view of sanitary and epidemiological requirements on the basis of technical means that have low complexity, small size and disinfecting performance consistent with the performance of the room-type air conditioners used.
