AIR CONDITIONING SYSTEM OF RAILROAD CARS (VERSIONS) Russian patent published in 2017 - IPC B60H3/00 B61D27/00 

FIELD: ventilation.

SUBSTANCE: air conditioning system contains the input return air duct (1), the inlet duct (2) for the outside air, connected to the chamber (3), mixing outside and return air. Over the mixing chamber (3) there are consequently arranged the main duct (4), which includes the fixed evaporation unit (5) and the supply air fan (6). Supply air fan is installed after the evaporation unit and the output discharge duct (7), feeding the treated air into the cabin. The system is provided with a block (8) of the ultraviolet air treatment (UAT), in which the UV light source - amalgamate lamps (13), which is preferably U-shaped. The block (8) is mounted in one or several of the following locations: before the mixing chamber in the inlet return air duct, and / or in the mixing chamber, and / or after mixing chamber before evaporation unit, and / or after the evaporation unit before the supply fan, and / or after the supply fan in the outlet discharge duct, wherein in the air duct body of the window unit for the air input and / or output can be covered with a protective grating, which is coated with titanium dioxide, absorbs UV radiation. The inner surface of the block (8) can be coated with absorbing ultraviolet radiation substance, or a coating reflecting ultraviolet light.

EFFECT: increase of the air disinfection efficiency, while extending the shelf life and service life of the system, people protection from UV radiation, reduce of the system sizes and simplification of its installation and maintenance.
