DEVICE AND METHOD FOR HEATING OF AIRCRAFT CABIN Russian patent published in 2009 - IPC B64D13/08 

FIELD: transportation.

SUBSTANCE: device (10) comprises the first manifold (12) of hot air supply, which leads to air conditioning unit (14), supply control valve (16) installed in the first manifold (12) upstream relative to air conditioning unit (14), and the second manifold (18) of hot air supply, which branches off from the first manifold (12) between supply control valve (16) and air conditioning unit (14), and bypasses conditioning unit (14). In order to provide for air conditioning in aircraft cabin in case of conditioning unit failure (14), from the first manifold (12) upstream relative to supply control valve (16) the third manifold (20) branches off for hot air supply, which connects the first manifold (12) to the second manifold (18). The second manifold (18) downstream relative to the point of its connection with the third manifold (20) extends in direction of aircraft cabin. In the second manifold (18) upstream relative to the point of its connection to the third manifold (20), the first isolating mechanism (24) is installed, which in closed condition prevents flow passage from the second manifold (18) to the first manifold (12). In the third manifold (20) upstream relative to the point of its connection to the second manifold (18), the second isolating mechanism is installed (22).

EFFECT: provides for possibility to control temperature in airplane cabin in case of failure of all air conditioning units available on board.
