Embodiment Construction

[0015] Describe the use of the present invention on the aircraft in detail below in conjunction with accompanying drawing.

[0016] Such as figure 1 As shown, the air is supplied by double air ducts, and a sound insulation layer is provided between the two air ducts for sound insulation and reducing heat exchange between the two air ducts. The outer air duct is connected with the air conditioning component through the air supply duct, and the inner air duct is connected with the return air duct. Therefore, what flows in the outer air duct is fresh dry air, and what flows in the inner air duct is circulating air. The pipeline switcher arranged along the outer air duct is automatically controlled by the sensor. When the fresh dry air drops to close to the temperature of the cabin air supply, the pipeline switcher here is switched, and the air flow no longer goes upward along the outer air duct, but Pass through the sound insulation layer through the branch pipe and enter the i...

Abstract

The invention relates to a double air channel wall for an airplane. The double air channel wall is characterized in that a double-layer air channel is arranged on a whole body of the airplane, and a sound-insulating thermal-insulating layer is arranged between an inner air channel and an outer air channel. Dry air flows in the outer air channel, so that water absorption quantity of an airplane body and the sound-insulating thermal-insulating layer can be reduced. In-cabin circulating air flows in the inner air channel. A plurality of pipe switchers are arranged along the outer air channel. When an air flow temperature of the outer air channel is lowered to approach a cabin air supply air temperature, air flow is sent to a cabin after entering the inner air channel through the pipe switchers to be mixed with the circulating air. A supply air duct is connected with the outer air channel and sends dry air sent by an air conditioning assembly into the outer air channel, and a return air duct is connected with the inner air channel and sends cabin return air into the inner air channel to circulate. Due to arrangement of double air channels, condensation and accumulation of moisture on the airplane body can be avoided, the airplane body is also fully utilized to serve as a heat exchanger, self weight of the airplane is reduced, and energy efficiency is improved.

Description

technical field [0001] The invention belongs to the fields of environmental control inside aircraft and aircraft manufacturing, and relates to a double-air-duct wall used for reducing water absorption and dead weight of an aircraft and reducing energy consumption. Background technique [0002] The environment in which modern commercial aircraft operate is extremely complex. The external air pressure ranges from 10.1kPa to 101kPa, and the ambient temperature ranges from -55°C to 50°C. When the aircraft is cruising, the surrounding air has almost no moisture content. While on the ground, the moisture content of the air can reach saturation. In such an extreme working environment, the presence of moisture can cause all kinds of problems. A commercial airliner absorbs a considerable amount of water during operation, especially one that frequently stops in areas of high humidity. Because there are many hygroscopic materials on the plane, including sound insulation and insulatio...
