本文提出了一种对传统四轮升压式高压除水制冷系统的改进方案,由原来的四轮系统同轴,即F-C-T1-T2同轴变成F-T2同轴与C-T1同轴。通过分析两种系统的设计点,进行优劣比较。本文分别从系统性能和可靠性进行比较,其中包含了系统在地面工作状态和高空工作状态的性能比较。通过详细阐述改进方案的优越性。为大型客机空气管理技术方案的选择提供参考。 In this paper, an improved scheme of the traditional four-wheel booster high-pressure water removal refrigeration system is proposed, which is changed from the coaxial of the original four-wheel system, that is, the FC-T1-T2 coaxial becomes the F-T2 coaxial and the C-T1 axis. By analyzing the design of the two systems, the pros and cons of comparison. This article compares the system performance and reliability, respectively, which includes the performance of the system in the ground working conditions and working conditions at high altitude. By elaborating the superiority of improving the scheme. It provides a reference for the selection of technical solutions for air passenger plane management.
