前言 笔者从工程学角度讨论了商业航空机舱内空气质量和人为因素的控制系统(ECS)。自使用活塞发动机和3人为一机组的时代以来,商业班机的环境控制系统已经发展为高度集成化、自动化的系统。它在给旅客提供舒适服务的同时,还兼顾到人的生理、经济因素、热效率、可靠性、易维修性以及购置成本等因素。方法 乘客呼吸的空气是从发动机的压气机抽取的,由空气循环冷却装置冷却,并与等量的、经过过滤的重 Preface The author discusses the air quality and human factors control system (ECS) in commercial aircraft cabin from the engineering point of view. Since the days of using piston engines and a three-person crew, the environmental control system for commercial airlines has evolved into a highly integrated and automated system. It provides passengers with comfortable service, but also take into account the physical, economic factors, thermal efficiency, reliability, ease of maintenance and acquisition costs and other factors. Method The air breathed by a passenger is extracted from the compressor of the engine, cooled by an air-circulation cooling device, and compared with an equal amount of filtered,
