AIR-CONDITIONING UNIT AND METHOD FOR DRYING AND MAINTAINING TEMPERATURE MODE IN BALLAST LAYER Russian patent published in 2015 - IPC E01B1/00 E01B27/00 

FIELD: construction.

SUBSTANCE: invention relates to railway engineering, in particular to the air-conditioning unit and method for drying and / or maintaining the temperature mode of the ballast layer. Railway track (10) has sleepers (14) lying on the ballast layer (12) and rails (16) lying on sleepers (14). Air-conditioning unit has chassis (30) to move the air-conditioning unit (24). Outlet nozzle (36) for air injecting, supporting the temperature mode in ballast layer (12) is connected to chassis (30), through at least one discharge region (26) disposed between two sleepers (14). Al least one protective plate (42) is oriented substantially opposite to the direction of action of gravitational forces of the upper side of the lateral strip (20) of the ballast layer. The upper side of the ballast layer (12), and / or at least one sleeper (14), and / or at least one rail (16) are air tightly isolated from outside of the discharge region (26), before the air supporting the temperature mode is injected to the ballast layer (12) through the discharge region (26).

EFFECT: maintenance of temperature mode of the ballast layer is achieved, by means of which the specified conditions of reaction can be created inside the ballast layer, in particular with respect to the moisture content.
