Air conditioning apparatus for a railway wagon intended for ventilation and air-conditioning of passenger compartments and for disinfection of the air entering the passenger cabin by the bactericidal ultraviolet (UV) radiation. The apparatus comprises an input 1 the recirculation duct, the inlet duct 2 to the outside air, connected to the mixing chamber 3 and recirculation air. During the mixing chamber 3 are successively arranged main duct 4, wherein the evaporator unit 5 are fixed and the supply air fan 6 and the discharge outlet duct 7 feeding processed air into the cabin. Furthermore, the device is provided with air treatment unit ultraviolet built after evaporation unit before supply fan housing and formed from air pipe 9, within which is mounted a source of ultraviolet radiation, namely, amalgam lamps 13, preferably, U-shaped. The inner surface of the unit 8 may also be coated with absorbing ultraviolet radiation. By introducing into the structure of the apparatus UOV proposed design unit in conjunction with amalgam lamps and applying to the part UOV coating unit absorbing UV radiation achieved technical result consists in increasing the air disinfection efficiency while extending the shelf life and service life of the device, as well as protecting people from UV radiation, moreover, the size reduction is achieved. 5 ZP f-ly, 3 Fig.Устройство кондиционирования воздуха для железнодорожного вагона предназначено для вентиляции и кондиционирования воздуха пассажирских салонов и для обеззараживания поступающего в пассажирский салон воздуха посредством бактерицидного ультрафиолетового (УФ) излучения. Устройство содержит входной рециркуляционный воздуховод 1, входной воздуховод 2 для наружного воздуха, подсоединенные к камере 3 смешивания наружного и рециркуляционного воздуха. За камерой 3 смешивания последовательно расположены главный воздуховод 4, в котором закреплены испарительный блок 5 и приточный вентилятор 6, и выходной нагнетательный воздуховод 7, подающий об
