Embodiment Construction
[0024] In order to describe the present invention more specifically, the technical solution of the present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments, and the described specific embodiments are only for explaining the present invention, and are not intended to limit the present invention.
[0025] figure 1 It is a diagram of a typical aircraft environmental control system, including main air handling components (primary heat exchanger, compressor, secondary heat exchanger, turbine, air mixing box, fan, air supply duct) and temperature PID controller, the system's After the outlet air temperature parameter is processed by the air processing unit, it is adjusted by the flow control valve regulated by the PID controller. The PID controller compares the temperature value of the feedback point in the cabin, and adjusts the opening of the flow control valve to control the outlet air temperature value. . ...
