The structure of the aircraft is precise, and the aircraft air-conditioning system is an important system module that supports the safe and stable flight of the aircraft, and plays a role in tracking and adjusting the environmental parameters of the aircraft cabin and equipment cabin.

Aircraft air conditioner is an environmental control device in the aircraft, which plays the same role of air conditioning as household air conditioners. So why can't you just put your home air conditioner on the plane? This is because aircraft flight is a dynamic process, and processes such as climbing, descending, and cruising face severe tests of vibration, air pressure, and drastic changes in temperature.

Almost all of the air circulating in the aircraft comes from the aircraft air conditioning system, which is a major part of the aircraft cabin environmental control system. The cabin environmental control system provides the following three functions: cabin pressurization, temperature regulation, and equipment cooling.
