Ventilation system for delivering air along aisle of aircraft cabin

Abstract

The invention discloses a ventilation system for delivering air along an aisle of an aircraft cabin. The ventilation system comprises air supply inlets and air exhaust outlets. The air supply inlets are formed in the top plate of the cabin aisle and the lower portions of seats on the two sides of the aisle, and the top air supply inlet is a pore plate or shutter air opening connected with the tailend of a top air supply pipe longitudinally arranged along a fuselage; the seat lower portion air supply inlet is in a long strip shape, is connected with a seat lower portion air supply branch pipeand is arranged on a seat structural part adjacent to the aisle in the direction of the fuselage, and a shutter is embedded in the air supply inlet; and the exhaust outlets are formed in the top plateclose to the cabin walls on the two sides and the top plate (suitable for a double-channel cabin) of the symmetry axis of the passenger cabin. The ventilation system comprises three independent air supply modes of high-speed air supply of the top plate, low-speed downward air supply of the top plate and downward air supply of the seat, which can be combined for use, a comfortable thermal environment can be provided for passengers and crew members according to different stages of getting on, getting off and flying, the air blowing discomfort caused by an existing replacement ventilation designto the feet of the passengers is reduced, and the air quality of the cabin is improved.

Description

technical field [0001] The invention belongs to the technical field of ventilation of passenger aircraft, and relates to a ventilation system for projecting wind along an aisle of an aircraft cockpit. Background technique [0002] With the process of globalization, airplanes are gradually becoming the mainstream means of transportation. Aircraft rely on the airflow patterns created by the cabin environmental control system (ECS) to provide a comfortable and healthy cabin environment. Reasonable airflow organization can make the pollutants in the cabin be discharged out of the cabin in the shortest way and in the fastest time, reduce the cross-mixing of the air in the cabin, and ensure that passengers can inhale relatively clean air. [0003] According to the mixing of supply air and cabin air, the airflow organization modes currently designed for the cabin can be divided into two categories: one is the mixed ventilation based on the dilution principle, which mixes the suppl...

AI Technical Summary

Problems solved by technology

The air supply outlets of the cabin replacement ventilation currently designed are located at the bottom of the cabin’s two side walls. When cooling the cabin, the cold air sent from the bulkhead directly blows at the ankles of the passengers, causing strong discomfort to the passengers.

In addition, the passengers next to the bulkhead are also affected by the cold radiation from the bulkhead, together with the cold wind blowing from the ankles, the discomfort is further aggravated
