The installation of various air duct components and operating mechanisms should be able to ensure their normal use functions and be easy to operate.
The air source of the air-conditioning system can be divided into two categories, one is the hot air flow drawn from the aircraft system, which enters the cabin under the action of the air-conditioning components; the other is the ram air from the outside, which is mainly used to cool the air from the aircraft system. The gas introduced to the air conditioning unit is discharged directly after use.
Aircraft air conditioners come from the bleed air of the air source system. The bleed air temperature of the air source system is very high and cannot be directly applied. The air conditioner must be cooled by the cooling component. The cooling component is cooled by the bleed air of the air source system and the external punch. The heat exchange of air is realized.
