波音737NG飞机的空调系统通过对机舱内的温度和压力进行控制,为旅客提供舒适安全的乘坐环境。737NG飞机主要通过调节冷热空气的混合比例来调节客舱温度。来自发动机的高温高压引气不能直接使用,需要经过空调制冷系统的降温,因此,空调制冷系统的性能直接影响空调温度的控制功能。空调系统作为飞机的重要系统之一,它的好坏不仅影响着旅客的舒适感,而且飞机结构和飞行安全也有重要的影响。
The air-conditioning system of the Boeing 737NG aircraft provides passengers with a comfortable and safe ride environment by controlling the temperature and pressure in the cabin. The 737NG aircraft adjusts cabin temperature mainly by adjusting the mix of hot and cold air. High temperature and high pressure bleed air from the engine can not be used directly and needs to be cooled by the air conditioning and refrigeration system. Therefore, the performance of the air conditioning and refrigeration system directly affects the control function of the air conditioning temperature. Air-conditioning system as one of the important systems of the aircraft, its quality not only affects the passenger comfort, but also the aircraft structure and flight safety also have a significant impact.
