Aircraft cabin temperature control system and method

Abstract

The invention relates to an aircraft cabin temperature control system and method. The aircraft cabin temperature control system comprises cabin bottom temperature sensors, cabin side wall temperature sensors, an outer environment temperature sensor, bottom temperature adjusting devices, side wall temperature adjusting devices and a controller, wherein the bottom temperature adjusting devices are mounted at the bottom area of a cabin and used for adjusting the temperature of the bottom area of the cabin, the side wall temperature adjusting devices are mounted at the side wall areas of the cabin and used for adjusting the temperature of the side wall areas of the cabin, and the controller is used for controlling heat required to be dissipated or absorbed by the bottom temperature adjusting devices and the side wall temperature adjusting devices according to the measured temperature of the bottom area of the cabin, the measured temperature of the side wall areas of the cabin, the measured aircraft outer environment temperature, a preset comfortableness value of the temperature of the bottom area of the cabin and a preset comfortableness value of the temperature of the side wall areas of the cabin. The aircraft cabin temperature control system and method have the following beneficial technical effect that the heat comfortableness requirements of different flight crews and different passengers under different conditions can be met.

Description

technical field [0001] The invention relates to an aircraft cabin temperature control system and method. Background technique [0002] Due to the wide range of commercial aircraft operations and the special operating environment, they will encounter all kinds of extreme weather, and different passengers have different requirements for cabin comfort. [0003] In summer, in some areas, the temperature is higher and the humidity is also higher. When the aircraft is on the ground, the skin temperature sometimes reaches above 50°C, and the air temperature in the cockpit of the aircraft will also reach above 40°C without the air conditioner turned on. However, when the aircraft is in the cruising state, the temperature of the outside atmosphere will gradually drop below -10°C. [0004] In winter, in some cold regions, the climate is cold, with low temperature and low humidity. When the aircraft is on the ground and in extremely cold weather, when the air conditioner is not turn...

AI Technical Summary

Problems solved by technology

[0009] It is difficult for the current commercial aircraft air conditioning air supply system to meet the comfort requirements of the human body in terms of temperature.

[0010] At present, the main cabin ventilation method used by most commercial aircraft is the top (cabin ceiling and luggage rack area) air supply mode, and the air supply volume and direction cannot be adjusted according to individual needs, and some technicians are based on this. The air supply method has been improved

[0011] In the patent 200480039503.4, a method and device for air conditioning of the aircraft cabin are mentioned, but this device is mainly a device for adjusting the direction and flow rate of the air supply in the ceiling area according to the air supply temperature in the ceiling area, and it is difficult to improve the air quality of the passengers. The comfort of the lower part can only change the temperature comfort of the upper body of the human body, the effect is very limited, and it cannot effectively improve the temperature stratification phenomenon from top to bottom of the cabin

Also does not improve temperature and thermal comfort at the bottom of the cabin and in areas near the side walls
