摘要/Abstract

摘要： 为了提高飞机座舱环境控制系统性能，同时降低设计和制造难度，提出了分体四轮式空气循环制冷系统。所提系统采用2个独立的两轮式涡轮冷却器代替一体化四轮式涡轮冷却器。基于焓参数法分析了分体四轮式及四轮式空气循环制冷系统的热力性能，结果显示2个系统热力性能一致。基于实验室现有部件搭建了分体四轮式空气循环制冷系统原理样机，摸底测试表明，系统最大制冷量可达12.0 kW，制冷量理论值与试验值的误差分布在±15%以内，验证了焓参数法的有效性。原理样机的性能系数分布在0.21~1.15之间。所提系统可为国产大飞机环境控制系统的研制提供良好的技术储备。

Abstract: In order to improve the performance of cabin environmental control system and reduce the difficulty of design and manufacture, the split four-wheel air cycle refrigeration system was proposed. Two split two-wheel turbine coolers were used instead of integral four-wheel cooler. Based on the enthalpy parameter method, the thermal performance of split four-wheel and four-wheel air cycle refrigeration system was analyzed. Results showed that the two systems have the same thermal performance. A prototype of split four-wheel air cycle refrigeration system was built and tested, and the maximum refrigeration capacity was 12.0 kW. The error between theoretical value and test value of refrigeration capacity was within ±15%, which verified the correctness of enthalpy parameter method. The coefficient of performance of the prototype was between 0.21 and 1.15. The spilt four-wheel air cycle system can provide research ideas for the development of domestic airliner environmental control system.

Key words: environmental control system, air cycle refrigeration system, four-wheel, enthalpy parameter method, prototype
