The invention relates to a low-energy-consumption zone-control deicing
system and a low-energy-consumption zone-control deicing method. Comprising a left / right wing compound distribution valve, an empennage compound distribution valve, a wing
front edge deicing sleeve, an empennage
front edge deicing sleeve and a controller, a plurality of sections of wing
leading edge deicing sleeves are arranged on the
leading edge of the left / right wing along the
wingspan direction in a partitioned manner, and a plurality of sections of empennage
leading edge deicing sleeves are arranged on two sides of the leading edge of the empennage along the
wingspan direction in a partitioned manner; the air inlet ends of the left / right wing compound distribution valves are connected with engine air sources on the corresponding sides through deicing pipelines, and the one or more wing leading edge deicing sleeves are connected with the outlet ends of the compound distribution valves on the corresponding sides through the deicing pipelines; the air inlet end of the empennage compound distribution valve is connected with a left / right engine air source through a deicing pipeline, and one or more sections of empennage
front edge deicing sleeves are connected with outlet ends of the empennage compound distribution valve through deicing pipelines; and the controller is in communication connection with the left / right wing compound distribution valve and the empennage compound distribution valve, opening and closing of outlet ends of the compound distribution valves are controlled according to a certain
time sequence, segmented deicing is achieved, and the consumption demand caused by an engine is reduced. The air bag is driven to act mechanically in a form of extremely low
power consumption, and'on-demand, accurate and instantaneous' release of deicing energy is realized.
