The invention discloses a construction ventilation system in a film type LNG (Liquefied Natural Gas) cabin, which comprises a dehumidification unit, an air supply system, an air return system, a smoke ventilator, a first fireproof valve, a second fireproof valve, a smoke sensor, an automatic water spraying fire extinguishing device, an automatic control shutter, a silencer, super glass wool and a central controller, the air supply system comprises a tenth-layer air supply branch pipe, a ninth-layer air supply branch pipe and a plurality of air supply branch pipes vertically extending to the fourth layer of the cabin, wherein the tenth-layer air supply branch pipe and the ninth-layer air supply branch pipe are arranged at the top of the cabin. The air return system comprises a third-layer air return pipeline which is connected into the cabin along the elevator shaft and extends to the lower portion of the cabin. According to the ventilation system, middle-upper-portion air supply and lower-portion air exhaust are achieved, and the problem of ventilation dead angles is solved; and the central controller is used for controlling, so that an automatic fire control effect is achieved.
