The opening of the flow control valve (FCV) is electro-pneumatic, and the valve is equipped with a stepper motor and a shut-off solenoid valve.
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.
The aircraft air conditioning air supply pipe is a pipe used to connect the ground air conditioning and the air conditioning air supply outlet of the aircraft. When the traditional air-conditioning air supply pipe is transported from the warehouse to the airport, it is very inconvenient to fold and store the air supply pipe, and it takes up a lot of space.
