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 a block ultraviolet air treatment inserted between the camera 3 mixing and evaporation unit 5 and formed from the body-air duct 9, wherein the ultraviolet air processing unit installed UV source as is used amalgam lamp 13, preferably, U -shaped. The inner surface of the unit 8 may also be coated with absorbing ultraviolet radiation. By introducing a block structure of an apparatus UOV proposed design in conjunction with amalgam lamps and applying to the block UOV coating 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
