Air supply and exhaust system for passenger cabin of passenger airplane

Abstract

The invention discloses an air supply and exhaust system for a passenger cabin of a passenger airplane, which comprises three parts, namely a ceiling air supply port, an individual ventilation opening and an exhaust port, wherein the ceiling air supply port is arranged on the ceiling above a seat, and for an integral row of seat, a ceiling air supply port is respectively arranged above an aisle close to two sides of the seat; the individual ventilation opening is arranged on a luggage rack above each seat, namely a separate individual ventilation opening is arranged above each seat to bring convenience to passengers for freely adjusting air quantity and air direction; and the exhaust port is positioned on the side wall of the passenger cabin close to the floor. The system provided by the invention avoids uncomfortable feeling caused by strong air flow of a scatter flowing type ceiling air supply port, adopts the grille type ceiling air supply port to facilitate forming even airflow, and is provided with the individual ventilation opening for the individual requirements of passengers; and the exhaust port is arranged on the side wall of a fuselage above the floor so as to prevent influencing the riding quality of the passenger cabin because the airflow picks up dust.

Description

technical field [0001] The invention belongs to the field of passenger aircraft environment control airflow organization, and in particular relates to a design suitable for ventilation and exhaust in passenger cabins and improving passenger comfort. Background technique [0002] Passenger comfort is primarily determined by cabin air temperature, airflow distribution and air quality. The air treated by the environmental control system is sent into the cockpit through the air supply port, exchanges heat and mass with the air in the cockpit, and then exits the cockpit. The continuous inflow and outflow of air will affect the flow field and temperature field in the cockpit, which will directly affect the comfort. The removal of pollutants in the air in the cockpit is closely related to the airflow organization. Therefore, in engineering design, attention must be paid to the airflow organization in the cockpit to better meet the comfort requirements of the passengers. [0003] ...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the problem of uneven distribution of airflow in passenger aircraft and strong wind in the aisle, which causes discomfort to passengers, the present invention provides a cabin air supply and exhaust system, which makes the airflow in the cabin uniform and the airflow velocity within the comfortable range of the human body, and Able to meet passenger's personal ventilation requirements
