摘要: 介绍了波音公司和空中客车公司环境控制系统的发展现状,提出了一种使用R134a工质的变频蒸发式制冷的环境控制系统,应用起飞总质量法进行了代偿损失分析,对给定飞行剖面上的能量消耗进行了计算及定性分析,并以燃油消耗为指标对新系统的能耗特性与采用空气制冷的环境控制系统进行了比较.新系统有效降低了燃油消耗(仅21.93kg/min,约是传统系统的40%),提高了飞行的经济性。系统的低噪音、灵活调节和无污染供气,能够提高座舱的健康、舒适度.Abstract: The advanced technology of environmental control system(ECS) from Boeing and Airbus was introduced. A new concept for ECS was raised, which applied vapor cycle refrigeration with frequency scroll compressor using refrigerant R134a. ECS penalty was calculated with the method of take-off gross weight. And the calculation and qualitative analysis were done for the new ECS energy consumption in the whole flight profile. Then the performance of the new ECS was compared with current ECS in fuel consumption. The results show that new system consumes less fuel(only 21.93kg/min, about 40% of traditional system), which could increase aircraft economic performance. And the health and comfort in cabin could be improved with the low noise, flexible regulation and clean air-supplying.
